EDWARD TUCKERMAN-A BRIEF SUMMARY OF HIS WORK.

Bruce Fink.

In a paper entitled “Two Centuries of North American Lichenology,” the present writer has called the time from 1847 to 1888 “ The Tuckermanian Period.” During this time everything in American lichenology was colored by the views of Tuckerman. Indeed Tuckerman stands out so pre-emin- ently as an American lichenist that something of his history is a proper part of the history of American lichenology. Born in 1817, he obtained his bache- lor’s degree in 1837, and two years later finished the law course at Harvard. In 1841 and 1842 he traveled in Europe and met the great lichenist, Elias Fries, at Upsala. Returning to this country, he accompanied Asa Gray to the White Mountains and began the difficult exploration which has rarely been excelled for completeness. That he began his botanical studies in early life and devoted himself chiefly to lichens from the first appears from the fact that his first “ Enumeration of Some Lichenes of New England” was published when he was not more than twenty-two years old, and appears to have been read the year before. Excepting Halsey’s “ Synoptic View ” this was the first work by an American, entirely devoted to lichens.

Tuckerman’ s writings, even from the first, contained careful notes which •show that he was possessed of a genuine love of botany and a marked adaptability for the work. Thus his meeting with Fries was not merely an incident of his first European trip, and his visits and excursions with this greatest lichenist of his time must have been a great inspiration in those days when botanists were few in number. Indeed, we can hardly estimate the value of this visit to American lichenology. In 1847, nearly ten years after Tuckerman began his work on lichens, appeared his “Synopsis of the Lichenes of New England, and other Northern States and British America.” This work was the first to give descriptions and a classification of our lichens, and though it contained but two hundred and ninety-five species, with twenty new, it was of great importance as it formed a basis from which others could work. At the same time Tuckerman began to issue his “Lich- enes Americae Septentrionalis Exsiccatae,” the first issue of American speci- mens giving authentic plants with which collectors could compare their' lichens.

Tuckerman was more than a lichenist as his knowledge of the general botany of his day was quite comprehensive, while he was a widely read and scholarly man. His professorship in botany at Amherst began in 1858 and continued till his death, twenty-eight years later. But we must confine our attention to his work upon the lichens. In this field his activity continued to the time of his death, and collections were determined by him, not only from all portions of the Western Hemisphere, but also from the Eastern Hemisphere and from the islands of the sea. How much labor and self-

The November Bryologist was issued November 1st, 1905.

sacrifice is involved in such a task will be appreciated by those who have attempted a similar one even though upon a smaller scale, in some field of taxonomic study. This work brought Tuckerman a knowledge of lichen species possessed by very few even of the European lichenists, and cul- minated in his two great contributions to North American lichenology, the “ Genera Lichenum ” in 1872 and the “Synopsis,” the first volume of which appeared in 1882 and the second in 1888. Of these two great works, we may venture a few words. The author was conservative in his view of genera and species and seemed to have followed Fries very largely in his classifica- tion of the American lichens. His views as to system of classification and as to generic and specific limitations can scarcely be expected to endure in all particulars. Yet his conservatism was by no means a fault, and has no doubt greatly aided in the study of lichens.

Tuckerman was to lichenology what Asa Gray was to the study of our seed-plants, and we cannot pay too high a tribute to the labors of these two men. Tuckerman's contributions to North American lichenology consist of forty-eight titles, but the number by no means measures the amount of work involved, for he aided others continually and much of his labor received no public recognition. Conservative as he was, his new species and varieties numbered some three hundred and sixty-five, about two hundred and fifty of these being found on the North American continent, some sixty of the remainder on the island of Cuba, and nearly an equal number from various parts of the world and not to be regarded as North American. Including the Cuban lichens named by Tuckerman, the number of species and varieties described in the two volumes of the “Synopsis” for North America, is approximately one thousand and fifty, and this number is no doubt consid- erably below the whole number of North American lichens known by Tuck- erman.

Tuckerman was pre-eminently a systematist, but some words are in order regarding his views on some other questions of lichenology. In regard to the theory of Schwendener as to the dual nature of lichens, he was more guarded in his statements than many of the other systematic lichenists of his day. While he readily admitted that there were some arguments in favor of the theory, he seems finally to have adopted the views of Minks, and like Muller and some others of his day, thought that he had himself demonstrated the existence of the “ microgonidia.” This he regarded as establishing a boundary line between lichens and fungi. It is pleasant to note, however, that during the years of sharp debate, Tuckerman was always careful and •considerate in his treatment of the question. It is also quite as pleasant a task to record that in a short paper entitled, “ Can Lichens be Identified by Chemical Tests,” Tuckerman remarks that his own observations have led him to believe that such tests are scarcely reliable, a view which doubtless meets the approval of later lichenists generally, since we have reached more definite knowledge regarding the anatomy of these plants.

Excellent memoirs of Tuckerman by Willey, Gray and Farlow give much more detail than can be incorporated here. Grinnell, Iowa.

LICHEN NOTES No. 2.

G. K. Merrill.

It is no unusual event for the collector to observe lichen species growing in situations utterly discordant with their natural habitat, but the recent finding by the writer of Umbilicaria pustulata, Hoffm., b. papulosa. Tuck., attached to one of the lower limbs of a young spruce seems worthy of a few words

Itis to be noted that the genus Umbilicaria is typically saxicoline, and the occurrence of an individual on any other substratum is distinctly a departure from habit. The plant was normal in appearance, well fruited, perhaps 60 mm. in major diameter, firmly attached to the branch, and apparently in no wise physiologically affected by its untoward surroundings. The branch was four feet from the earth, living and thrifty, and the tree was one of numbers growing in the vicinity. The locality was ledgy and numerous outcroppings supported myriad Umbilicariae of similar and diverse species. Speculating on how the plant received its start in an uncongenial habitat, it is inconceivable that it should have been a nomad. While well known that fragments of lichen thallus, wind blown or moved by other agencies, may and do become attached to new supports, it is equally a fact that the anchor- age of the Umbilicariae is very secure whether in their younger stages or as matured. Then again we have no observations to prove that a new attach- ment may be formed once the old is broken, either through the same umbili- cus or by growth of a new one. It seems a safe conclusion that our plant originated precisely as others of its kind do, and in situ. It has been men- tioned that the spruce was a young tree, and the consideration suggests itself that a fairly accurate idea of the lichen’s age might be deduced should that of the tree be ascertained. This was found to be slightly less than thirty years, but the information in establishing one limit fails to furnish a mimi- mum. While reasonable to infer that from the branch being one of the largest, it was also one of the oldest, assumption can scarcely go further, and certainly not to that limit of fixing a time for the meeting of the proto- thal- line film with its algal affinity. We can be sure that the tree had passed its juvenile stage, that the branch had acquired some size and a developed cor- tex. All this may have acquired ten years ; if so, how extraordinarily moder- ate are the functional activities of a lichen only attaining to a diameter of 60 mm. in twenty years. That lichens derive their inorganic components from the substrata has long been asserted, the rhizoids supposedly furnishing the deus ex machina . If this be true of Umbilicaria (it seems incredible) our plant evidently found the assimilated products of the host branch entirely to its liking, and if so,' why should it have been unattended? Why not more individuals on the same branch, other branches of the same tree, or other trees of the same species and locality? Indeed the same interrogations might be made if it were a known fact that lichens derive their nutrition solely from meteoric sources.

A very curious lichen received during the summer of 1904 from Mrs. L. A. Carter, of Laconia, N. H., finds a name, the result of a recent examina-

— 4—

tion of the Cetrariae in the Tuckerman herbarium. The plant was collected in Central Point, Oregon, by Mrs. Agnes Ashworth, and as we are informed by Mrs. Carter, grew inmixtwith Everniavulpina . While the thalline char- acters were obviously those of Cetraria. patient search on our part failed to find a specific name. A portion of the specimen sent to Prof. Fink drew a statement that it was new to him, “ that it seemed nearest to Cetraria Rich- ardsonii ,” although he was not sure. In May, 1905, through the kindness of Prof. John Macoun, we received a suite of the lichens collected by him during the summer of 1904 in the Rocky Mountains. No. 7 of the set from Glacier, British Columbia, found on bushes, proved to be like the Oregon plant above mentioned, except a better specimen. Prof. Macoun had marked the packet Cetraria scepincola , but admitted a doubt of the correctness. More search and study on our part still failed in satisfactory reference, and our final word in the interchange of opinion with Prof. Macoun was, that if Cetraria Islandica was known ever to grow on trees or shrubs, our plant might be that form. At a later date, gathering from Th, Fries, Lich. Scan. Pt. I. p. 98, that small forms of the species were sometimes to be found on wood, we were quite prepared to find that Tuckerman knew the form, although this habitat was not mentioned in the Synopsis. The specimens appearing in Tuckerman’s collection all come from West America, and in addition to being marked C. Islandica have a qualifying sub-label “ aboricolaC It is not believed that the word is used to designate a particular variety or form of C. Islandica but merely as descriptive of its habitat. This opinion is borne out by Tuckerman’s frequent use of “ aboricola ” throughout his herbarium to designate corticoline forms. Unlike the Umbilicaria of our first topic, which presented no divergence from normal appearance, this plant varies not a little, as may be seen by comparison of the appended description with Tuckerman’s a.

Cetraria Islandica (L.) Ach.

*M. arborialis (conditional nomination).

Thallus cartilagineous, foliaceous, sub-erect or now appressed ; lacinae plane, variously and irregularly divided, the apices commonly obtuse, from narrowed to sometimes four mm. in breadth, very smooth and shining or sub-opaque : greenish-olivaceous or olivaceous-fucescent, the margins of the lacinae either spinulose or not, in the later case sometimes white- sorediate. Apothecia not observed.

The lacinae seem to be held to the twigs not by rhizinae, but by an obscure adglutinated intergrowth. No trace of the sanguineous color char- acteristic of the basal portion of the type plant is observed. The resemblance of the plant to some forms of C. ciliaris is sufficiently marked to suggest the thought of its being factorial in the phylogeny of that species. It is rather re- markable that Tuckerman gave no space to the form, and it might be taken that he considered it of no importance. However this may be, the plant varied sufficiently in habit to be extremely puzzling to the writer, and on present evidence diverges enough from the normal presentments of C. Island- ica to be regarded as a distinct form. Rockland, Maine.

CEPHALOZIA FRANCISCI (HOOK.) DUMORT.

Cephalozia Francisci being an American as well as European species [see Torreya, 3:40. Mr. 1903, in which I recorded the fact of having detected it in a collection made by Mrs. Alice R. Northrop, near Prospect Harbor, Maine], I have thought I would publish some drawings of it as it has never been figured in our books. In its habit this Cephalozia shows the same charac- teristics as the genus Odontoschisma, except in its regularly bifid leaves and a few minor details : the obtuse lobing of the leaves, however, is unusual among the Cephalozia. Even this exception loses some of its importance when it is remembered that both O. Sphagni and O. prostratum show, in very rare cases, bifid leaves obtusely lobed. Its upright flagella-like gem- miparous branches recall those of O. denudatum, in miniature. Dr. Evans has given the above facts in the Botanical Gazette (36:337, N. 1903) and shown it to be one of the connecting links between the two genera ; he also mentions that it was principally on account of this species that Spruce included Odontoschisma among the sub-genera of Cephalozia. The speci- mens found in Maine grew on a shady path in company with C. bicuspidata (L.) Dumort, and formed little compact tufts, showing perianths with imma- ture sporogonia and immature androecia. I am in hopes of soon hearing of its occurrence at other stations and add a short description of it.

The pallid-green plant is sometimes tinged a clear wine-color ; leaves oval to orbicular, alternate, strongly imbricate at apex, spreading at base, obliquely attached, concave, sinus acute, lobing very obtuse : erect stems bear-

— 6 —

ing many crowded, imbricate leaves, prostrate stems with leaves scattered, all bifid one-fourth their length ; leaf cells large and pellucid, 30-49// with small trigones, cell walls otherwise slightly thickened : underleaves delicate, bifid, appressed or spreading. Dioicous. Androecium suberect, bracts large, four to five pairs, bifid, imbricate and each bract complicate, lobes wide- spreading, apices rounded, obtuse to apiculate, these bracts all having rhizoids, excepting apical pair ; antheridia small, oval, short-stalked. Perianth 10-12 mm. long by 5 mm. wide, almost three-carinate from base, mouth six-plicate, rep and. Spruce says that the perianth at base is three cells, in middle two cells thick : in the Maine plant I found it to possess a thinner wall, two cells thick one-third its length; bracts in about three pairs, large, bifid, recurved : capsule dark reddish-brown, oval-cylindrical : gemmae green, triangular, in globose mass at apex of flagellate branch, with scattered spreading leaves. Spruce mentions rose-colored gemmae, Hooker, green.

Bryum distantifolium Card. & Ther.

Tufts soft, brownish, about 5 cm. high. Stems erect, sparingly radicu- lose, simple or sending out 5-5 slender innovations above. Leaves dimor- phous, all entire, narrowly but distinctly decurrent; margins plane or subrevolute at base only, the lower leaves distant, small, short acuminate often obtuse or subobtuse, 0.9 mm. long, 0.5 mm. broad, border wanting or indistinct, costa not excurrent, the middle and upper leaves less remote, larger, 2-2.4 mm. long, 0.9 mm. broad, lanceolate, long acuminate, costa 70// thick at the base, short excurrent in a reddish cusp; median cells rectangular, 60-80// long, 15 /i broad, marginal cells narrow, linear, forming a border of two or three rows.

Assiniboia: Wood Mountains (Macoun, 1895. Sent as B. erythrophyl-

loides Lindb.)

Somewhat recalling the slender forms of B . pallens Sw. , but differing by its dimorphous leaves, which are plane on the margins or nearly so. The leaves decurrent at base, the upper distinctly limbate, at once distinguish this moss from Kindberg’s B. erythrophyllum and B. erythropylloides .

Bryum dimorphophyllum Card. & Ther.

Apparently dioicous, rather robust. Tufts compact, cohering, yellowish- green above, densely rufus-tomentose within. Stems erect, 4-5 cm., fre- quently branching. Leaves erect when dry on twisted branches, erecto-patent when wet, dimorphous, the lower very concave long-ovate or oblong from a long decurrent base, costa vanishing below the apex, upper leaves larger and

— 7-

narrower, 2.2 mm. long, 0.8 mm. broad, lanceolate, a'cuminate, acute, less decurrent, costa percurrent or shortly excurrent; margins all entire and revo- lute from the base to near the apex ; cells quadrate, short-rectangular or rhomboidal, 30/^ long, 14/4 broad, slightly chlorophyllose, with thick walls, marginal cells narrower and linear. Perichaetial leaves smaller, narrower* acute ; costa shortly excurrent. Capsule nodding or pendulous, narrowly sub- pyriform, 3 mm. long, 0.9 mm. thick, slightly constricted under the mouth both when wet and when dry; operculum concave-conic. Seta dark reddish-brown about 2 cm. long. Annumus broad, triple. Membrane of the inner peristome high, cilia 2-3 appendiculate. Spores smooth, unequal, some frequently ii/i in diameter, others more rarely 18 /j. in diameter. Male plants unknown. Plate XIX.

N. W. Montana: Mt. Lottie Stanton and Mt. Trilby, in the vicinity of

Lake MacDonald, Flathead Co., 1100-1800 alt. (J. M. Holzinger and J. B. Blake, 1898).

Belongs to the group of B . pseudotriquetrum Schw. , but is at first sight distinguished from all the other species of this group by its dimorphous leaves.

Aulacomnium palustre Schw. var. dimorphum Card. & Ther.

Stems densely branched above. Leaves dimorphous, stem leaves elongated acutely acuminate, apex sinuate, subdenticulate, strongly papil- lose ; branch leaves much shorter, obtuse, entire, less papillose, sometimes smooth.

Colorado: Near Breckenridge, 175 km. from Denver, alt. 3000 m. (J. M.

Holzinger, 1896).

A similar form is recorded by Mr. Dixon in his admirable Handbook of British Mosses, p. 282.

Aulacomnium palustre Sch. var. lingulatum Card. & Ther.

Slender, in the larger forms similar to A. androgynum. Leaves lingu- late, all obtuse, entire or faintly sinuate at the apex.

Colorado: Bog near Chamber’s Lake (C S. Crandall, 1894; herb, J. M.

Holzinger).

Distinguished from the var. imbricatum Br. Eur. by its smaller size and its longer not imbricated leaves.

Fontinalis subcarinata Card.

Soft, yellowish or dirty green. Stems 1 5-20 cm. long, denudate in the lower part ; branches elongated, erect, attenuate, subcuspidate. Leaves soft four- ranked, erect, 4-5 mm. long, 1-2 mm. broad, narrowly lanceolate, long acumi- nate, , entire or subdenticulate at the apex, nearly all distinctly sulcate in the middle, the lateral leaves subconduplicate; cells very long and narrow, the alar cells few, small, hardly distinct, often nearly wanting. Other charac- ters unknown. Plate XXIII.

Assinoboia: Cypress Hills, Battle Creek (Macoun, 1895. Sent as F.

Lescurii).

This species belongs to the Sect. Malacophyllae , and is closely allied to

— 8—

F. seriata Lindb., but differs from it by its plicate leaves, with less distinct alar cells.

Climacium Americanum Brid. var. pseudo-Kindbergii Card. & Ther.

Habit in all respects of C. Kindbergii but the areolation agrees exactly with C. Americanum.

Missouri: Paw Paw Junction, on old log; Pleasant Grove, on wet bank

(C. F. Bush, 1897 and 1899).

Contrary to the opinion of Dr. A. J. Grout, we think that C. Kindbergii cannot be distinguished specifically from C. Americanum. We have speci- mens on which the distinctive characters become attenuated. The plant of which we make the variety psuedo-Kindbergii is just one of these forms. Brachythecium subasparrimum Card. & Ther.

Loosely intricate-caespitose, yellowish-green, rather glossy. Stem slen- der, 3-6 cm. long, prostrate, radiculose; branches unequal, attenuate, ascend- ing, pinnate. Stem leaves erecto-patent, deltoid from a decurrent base, gradually longly and narrowly acuminate scarcely plicate, nearly smooth, 1.8-2 mm. long, 0.75 mm. broad, margin slightly reflexed at base: subentire or slighly serrulate at base; costa narrow, 36/* thick at base; median cells linear, narrow, 60-85/* long, 6/* broad, basal cells laxer, hyaline, rectangular or subhexagonal ; branch leaves oblong, long and narrow- acuminate, neither deltoid nor decurrent, more distinctly plicate, 1.6 mm. long, 0.5 mm. broad, margins revolute for a greater or less distance, minutely denticulate above. Perichaetial leaves ecostate, ovate from a clasping base, abruptly narrowed into a long slender, entire, spreading or reflexed acumen. Capsule inclined or subhorizontal: ovate- gibbous, slightly constricted under the mouth when dry, 1.7 mm. long, 0.8 mm. broad; operculum unknown. Seta dark red, 1.5 cm. long, very rough, densely covered with high papillea. Peristome perfect, cilia appendiculate. Spores 15 /* thick. Apparently dioicous (male flowers unknown). Plate XXIV.

British Columbia: New Westminster (A. J. Hill, 1902: herb, C. F.

Baker).

By the habit, dioicous inflorescence and very rough pedicel this moss stands near B . asperrimum (Mitt.) Kindb. and A*. Was king tonianum Eaton, differing from both in having 'the leaves scarcely plicate, almost smooth with the acumen much longer and narrower, and the borders very slightly denticulate or subentire and partly revolute.

Plagiothoecium sulcatum Card. & Ther.

Monoicous in rather lax, depressed tufts, glossy. Stems slender, creep- ing; branches ascending, subarcuate, about 1 cm. long, rather flattened. Branch leaves loosely subdistichous-homomallous, 1.2-1.5 mm. long, 0.4-0. 5 mm. broad, not at all decurrent, lanceolate, gradually long-acuminate, mar- gins plane, serrulate from the middle, sometimes from the base ; costa double, short or sometimes longer with one fork reaching almost to the middle ; cells narrowly linear, 70-90/* long, 6/* broad, the lower cells shorter, laxer, not porose, 20-40/* long, 12-15/* broad. Male flowers growing near the female.

— 9 -

Perichaetial leaves erect, appressed, ecostate, short-ovate, apex rounded, abruptly short-opiculate. Capsule sub-horizontal or inclined, 2 mm. long, 0.7 mm. thick, subcylindric, arcuate constricted below the orifice when empty, deeply sulcate in both young and mature stages ; operculum obtuse conical. Seta pale-red, delicate, flexuous, 2 cm. long. Annulus double, Peristome perfect, 0.42 mm. long, cilia nodose, minutely papillose. Spores smooth, 12 ju in diameter. Plate XXIV.

North Minnesota: On Fall Lake, near the foot of Kawasatchong Falls,

11 km. north of Ely (J. M. Holzinger, 1897. Sent as P. Muehlenbeckii Br. Eur.).

This moss seems somewhat intermediate between P. striate llum Lindb. (P . Muehlenbeckii Br. Eur.) and P. silesiacum Br. Eur., differing from the former by its non-decurrent leaves, narrower at base, with a more distinct costa, its much longer cells, the basilar ones not porose, its more arcuate cap- sule, and the form of its perichaetial bracts ; and from the latter by its cap- sule being deeply sulcate, even when young, and its more compressed branches. According to the description, P . pseudo silesiacum Sch. differs from our species by its much shorter pedicel (1 cm.), and its costate leaves. Plagiothecium Groutii Card. & Ther.

Monoicous, delicate, glossy, in rather dense depressed tufts. Stems slender, prostrate with numerous short complanate branches. Leaves minute flattened distichous, erecto-patent, 0.7-0. 8 mm. long, 0.3-0.35 mm. broad, not decurrent ; oblong lanceolate, the lateral subcultriform, with a shorter and broader acumen : margins plane, ecostate, stem leaves subentire or obso- letely denticulate, branch leaves in the upper third or from near the middle, minutely but distinctly serrulate; median cells linear, very narrow, 60-90 ju long, 6 ju broad, the upper cells shorter, the lower rectangular, the lowest larger and subdilated. Perichaetial leaves oblong, abruptly short-cuspidate, subentire or the lowest with sinnolate tip. Capsule horizontal inclined or sub- erect, ovate, minute, hardly 1 mm. long, o. 5-0.7 mm. thick, smooth, not con- tracted under the orifice when dry ; collumn short ; operculum rostrate. Seta slender, erect, reddish, 1-1.5 mm. long. Spores irregular, 8-29 /j, in diameter. Plate XXIV.

Hempstead, Nassau Co., N. Y. : Depression in base of a chestnut tree (A. J. Grout, i899t

Allied to P. elegans Sch. , but easily distinguished from it by its short leaves, more abruptly and broadly acuminate, the rameal rather strongly denticulate in the upper third, the perichaetial bracts subentire with a shorter acumen, the capsule smaller, the beak of the lid thinner and the monoicous inflorescence.

Amblystegium laxirete Card. & Ther.

Belonging to the group of A. riparium , quite robust, floating, dull- green, as much as 10 cm. in length, remotely pinnate, branches unequal, slightly spreading, attenuate, laxly foliose. Leaves flattened, distichous, spreading, ovate-lanceolate a little more shortly acuminate, about 3 mm.

— IO —

long, i mm. broad, margins plain, entire; costa strong, ioo ju thick at base, vanishing far above the middle, areolation lax, cells 60-80/* long, 12/* broad, walls thin and soft. Other characters unknown. Plate XXV.

Missouri. Monteer, in spring (B. F. Bush, 1899).

The leaves shorter acuminate, the longer and thicker costa and chiefly the loose areolation, at first sight distingnishes this moss from A. riparium. The last character also separates it from A. vacillans Sulliv. From A. Kochii Br. Eur. it differs by its larger leaves and its much stronger and longer nerve.

Hypnum malacocladum Card. & Ther.

Monoicous, fine, soft, rather lax, yellowish-green. Stems filiform, pros- trate, denuded/; branches ascending, about 1 cm. long. Leaves quite dis- tant, soft, concave, spreading, 0.8-1. 1 mm. long, 0.4-0.5 mm. broad, strongly narrowed from an ovate base or oblong, very broadly or shortly acuminate, apex rounded or subacute, margins plane, entire, costa thin, simple, extend- ing to the middle or beyond, sometimes subfurcate above, 35-40/* thick at base ; alar cells rectangular or subhexagonal hyaline, but not forming dis- tinct auricles ; median cells shorter rhomboidal, with thicker walls. Per- ichaetial leaves erect, longer acuminate, costate; capsule horizontal or obliquely erect, short, gibbous, 1-1.5 mm. long, 0.7 mm. thick: opercu- lum convex-apiculate, Seta short, rather thick, reddish, 8-10 mm. long. Annulus simple, distinct. Peristome 0.4 mm. long, segments of the inner peristome narrowly gaping at the keel, slightly papillose above; cilia 1-2. Spores 12 ju in diameter. Plate XXV.

BOOK REVIEWS.

Organography of Plants, especially of the Archegoniatae and Spermo- phyta, by Dr. K. Goebel, Professor in the University of Munich. Authorized English Edition by Isaac Bayley Balfour, Professor of Botany in the University of Edinburgh. Published at The Clarendon Press, Oxford.

The first volume of the English translation appeared in 1900. Part II was issued last summer. A brief synopsis of the references to the Bryophyta, in both volumes, may be of interest and stimulate to further study of the liv- ing plants.

New Formation of Organs in Regeneration: “In mosses the propaga-

tive capacity is uncommonly great; one may almost say that nearly every cell of the vegetative body in mosses and liverworts, and in fact also the

— II —

cells of the sporogonium which is generally still capable of development, can give rise to a new plant. In the regeneration of the mosses a new plant is not produced directly, but & protonema is first formed from which the plant arises, in the same way as the juvenile stage of the plant is developed from the germination of the spore.” This is contrasted with the liverworts and suggestions are made for further experiment. A few instances of phenom- ena of propagation in Bryophyta are cited, such as Marchantia. Dorsiventral organs are described and orthotropous and plagiotropous positions are illus- trated by Hylocotnium splendens and Mnium undulatum . Anisophylly, or the differences in size between upper and lower leaves is illustrated by Cycithophorum pennatum and reference is made to Rhacopilum and Hypopterygium. Several hepatics are also cited.

Juvenile froms and stages of development are illustrated in Lejeunia Metzgeriopsis, Ephemerum serratum and Funaria hygrometrica, and a cushion of protonema of a species of Bryum in Fig. 90 is a remarkable instance of an unusually large development of this stage of growth.

Investigations on the directive influence of light in the polar differentia- tion of the spores of many Bryophyta and its influence in the formation of roots are still wanting. The question of the influence of light on the position of the capsules in mosses still requires experimental investigation. Differ, ences are cited between Sphagnum , Orthotrichum and Grimmia and Bux- baumia and Diphyscium, Barbula , Catharinea and Bryum .

The first section of the second volume deals with the sexual organs of the Bryophyta with illustrations from Marchantia polymorpha, Phascum cuspidatum , Funaria hygrometrica , Catharinea undulata , Monoclea dila- tata , Sphaerocarpus, Blyttia. Jungermannia, and Mniuin undulatum.

The vegetative organs of the Hepaticae, the asexual propagation, the phenomena of adaptation in order to retain water and resist drought are described and figured in detail as well as the protection of their sexual organs and the types of sporogonia and their development, and the germination of the spores.

The life history of various mosses is described from the germination of the spore, the development of the protonema, the formation of roots, stems and leaves, their special forms and functions, their arrangements for retain- ing water, and resisting drought ; their relation to light, the development of the sexual organs ; the structure of the sporogonium and its various types and adaptations for shedding the spores.

A few quotations will suffice to show how suggestive of further study and experiment these chapters on the Bryophyta are: “ There is wanting in the musci the wealth of adaptation in the form of the leaf in relation to the retention of water that is so manifest in the Hepaticae : the complex auricles are absent. Outgrowths of their surface, such as mamillae or papillae, occur in species growing in dry sunny places, such as Hedwigia ciliata , but not on hygrophilous species, and would probably disappear if cultivated in moisture and shade. The method of sponge construction by means of empty cells with perforated walls, is well shown in Sphagnum and Leucobryum ; one is fitted to evaporate water rapidly, the other to retain it.”

— 12 —

A list of the illustrations would be too lengthy as there are ninety-seveu of the Hepaticae and thirty-three of the mosses.

The connection between the Bryophyta and the Pteridophyta is dis- cussed, although positive results have not been reached.

This book promises to be very stimulating to the student of mosses and hepatics as living organisms, and will encourage further study along the lines so clearly indicated. Elizabeth G. Britton,

The Fern Allies of North America, north of Mexico, by Willard N. Clute. With more than one hundred and fifty illustrations and eight colored plates, by Ida M. Clute. Published by Frederick A. Stokes Co., New York City, at $2.00.

This is a companion volume to the author’s “ Our Ferns in Their Haunts,” and describes in technical language the scouring-rushes, horsetails, running-pines, club-mosses, water-ferns, pillworts, water-peppers, quillworts and the various other plants included among the Fern Allies. The illustra- tions are most helpful, especially the black and white cuts. The claim is made that here all our species are illustrated and many for the first time. The book also contains a check-list of the North American species with syn- onomy, a complete glossary, and seven keys to the genera and species based on the most noticeable characters. In the matter of nomenclature our author claims to have adapted a somewhat conservative treatment, using for the most part the names common in other works of this class. This notice is intended merely to call the attention of our readers to a good book to add to their equipment for next season’s outdoor work and not as a critical analysis. The book is well made up, though the printing as to type is not all one could desire. The black and white drawings are clear and characteristic of the species treated. The colored plates in our opinion add nothing to the value of the illustrations. A. M. S.

CHAPTER NOTE.

In connection with the admission to membership in the Sullivant Moss Chapter of persons who are not resident in the United States or Canada, the question has arisen as to how they may participate most easily in the offerings published in each issue of the Bryologist. In view of the fact that foreign letter postage is more than double that of domestic, it seems unfair to impose upon our foreign friends the added cost of transportation. Hence the following scheme is put forward:

—13-

Members offering specimens are requested to send to me at the address below a quantity of their offerings sufficient to meet the demands of the foreign members. Then if those members who are not residents of the United States or of Canada, will send me a list of such specimens as they wish to have, accompanied by stamps, even of their own countries, I will for- ward to them the specimens desired. If the foreign members wish to offer specimens, they may, if they wish, send me their entire offering and I will gladly undertake the distribution of the same. In each case, those speci- mens which are not distributed will be returned to the owners if they so desire.

This scheme is, of course, not obligatory, it being proposed merely as a means to facilitate the exchange of specimens.

REPORT OF THE PRESIDENT.

To the Members of the Sullivant Moss Chapter:

During the year just ended the affairs of the Sullivant Moss Chapter have progressed most satisfactorily. The increase in membership has been constant, the quality of the work done has steadily improved, and the mem- bers have shown a rapidly increasing ability to determine their own collec- tions.

The most noteworthy happening is the welcome decision to admit to membership persons not residents of the United States or Canada. At the present writing eight foreign members are on the Chapter roll. This fact to me seems most hopeful, inasmuch as it marks a decisive step towards broad- ening the usefulness of the Chapter and facilitates keeping in touch with bryological and lichenological activity elsewhere. For the present at least, the main efforts of the Society must be directed towards the stimulation of a

-14-

broad and active interest in the study of North American lichens, hepatics and mosses, yet it is equally important never to lose sight of the fact that only through intimate relationship with workers in other fields can any prob- lem be solved.

Another pleasant indication is the interest shown by many members in the careful exploration of their local floras. It is difficult to overestimate the importance of such work. Miss Haynes’ note upon Telaranea in the Novem- ber Bryologist well illustrates the ignorance of distribution which exists in the study of the hepatics ; among the students of mosses and lichens similar conditions obtain. It is not so much the knowledge of new species that is needed, as a clearer understanding of the variability and distribution of those species which have already been described. Hence I suggest, as a most profitable field for work, the intensive study by the members of those species which occur in their own regions, the notes made being supplemented by specimens in each case.

One other point needs a word of emphasis. It is the importance of pre- paring neat, representative specimens of common species. Almost anyone will take pains with a rare specimen: few use the same care when preparing plants from their own dooryard. Many workers have been greatly annoyed at the receipt of specimens of the larger mosses, such as Poly trie hum com- mune, with the setae broken and the stems so bent and curled that “wad” seemed the only word applicable.

In closing I wish to extend my hearty thanks to the members for their many kindnesses during the past year. To all members, new and old, I extend my best wishes for the new year. Edward B. Chamberlain,

President.

REPORT OF THE SECRETARY.

During 1905 the Chapter has gained twenty-three new members and has lost but three, making the present membership one hundred and fifty-six. No deaths have been reported.* We have representatives in twenty-five States, the District of Columbia, British America, England, France, Japan, and Australia.

The Chapter Herbarium has also increased in size and value, and con- sists of one thousand, six hundred and thirty specimens — four hundred and eighty-one species and varieties, and one hundred and twelve genera. Three hundred and thirty specimens have been added this year, one hun- dred species being new to the Herbarium. Beginners have been supplied with authentic specimens, and they in turn have sent in many interesting species for determination. Dr. Grout, Mr. Cresson, Mr. Hill, Miss Wheeler, and many others have contributed largely to the Chapter Herbarium.

Ninety-one specimens — sixty-seven mosses, twelve hepatics, and twelve lichens— have been offered in the Bryologist during the year. It has been suggested that each member of the Chapter should try to offer “ at least one specimen a year,” as uncommon as possible, and if this suggestion were acted upon, it would greatly facilitate the work of the Secretary, who would

— 15—

by these voluntary offerings be spared the necessity of sometimes making personal application for them. During the past year twenty-eight members have distributed specimens, a little over one-sixth of the entire membership. It seems hardly fair that this willing sixth should be allowed to do all of this kind of work, and I have ventured to bring the matter to the attention of the members, some of whom are probably unaware that such offerings would be acceptable. I would also urged them to remember the Chapter Herbarium more frequently. Possibly some who would gladly distribute specimens are deterred by thinking they have not enough of any one species: and perhaps it would be as well to state that a package of moss or lichens or hepatics, collected as suggested by Mr. Chamberlain in the Bryologist for November, 1905, that will make from twenty-five to thirty fair-sized speci- mens will generally be sufficient for an offering.

In retiring from office, I wish to express to the officers and to the other members my grateful appreciation of their unfailing kindness and courtesy: I shall always recall with pleasure my official connection with the Moss Chapter, and thank my many correspondents for their expressions of appre- ciation and good will.

I know that all join me in extending a hearty welcome to our new officers, Mr. Merrill and Dr. Bailey, both far too well known to the members of the Chapter to need any further introduction.

Respectfully submitted,

Mary F. Miller.

REPORT OF THE HEPATIC DEPARTMENT.

It is my pleasant duty to report the steady interest in the Hepaticae, ■evinced by the members. The several large collections sent in from Wash- ington, Maryland, New York, New Hampshire, Maine, Canada, and Nova Scotia have, with the smaller ones, made up into five hundred pockets. Of these two hundred and thirty-two are duplicates, which are ready for exchange. Some of these collections I shall hope to dwell upon later, for they have added many interesting and several rare species to the Herbar- ium. I would like also to mention our obligations to Dr. A. W. Evans for his courteous and kindly assistance in verifying and determining a number of the specimens. Repectfully submitted,

Caroline Coventry Haynes.

REPORT OF THE LICHEN DEPARTMENT.

Interest in the Lichens is sustained, and much material has been sent in for determination. Many of the members have accumulated really com- mendable collections of their local flora. More could be accomplished if a good elementary manual was accessible. In this connection it is strongly urged that those interested workout their known species by aid of Mr. Sar- gent’s “Key” in the November Bryologist. No glossary will be required other than a good dictionary. The exercise will be found entertaining and helpful. The series of papers by Mrs. Harris should not be neglected, they are valuable guides when used intelligently. The remarks of Mr. Chamber- lain in the Bryologist, 8:6, 1905, are as Joshua Redearth says, “pintedly good medicin’ but hard to s waller.” It will be well for those contemplating an offering to send in their material for verification, or if such a course is inadvisable, state on the label that the specimen is determined by compari- son (and by yourself) with one submitted to the authority. All interested in the Lichens are assured of our hearty co-operation in furthering their knowl- edge of species or any other factor of the study. G. K. Merrill.

FURTHER NOTES ON CLADONIAS. VI.

Cladonia cariosa.

Bruce Fink.

As promised in the last paper of this series (Bryologist, 8: 3, 1905,) we will consider Cladonia cariosa in the present one. And in so doing we shall depart somewhat from the views of Wainio regarding species. The method of making a specific description stand for a compound conception, such as a genus or a subgenus, is manifestly bad and allowable only when our studies will not enable us to make a closer analysis. Dr. Wainio has employed the method of deliberately recognizing compound species and then adding vari- eties which are supposed to cover all known forms, designating the varieties by various names prefixed by alpha, beta, etc. After so doing, he fre- quently has determined species for the present writer without referring to any one of his varieties. This is the case in the present species, the large majority of the specimens sent Dr. Wainio being simply returned as Cla- donia cariosa. Thus it appears that after devising a uniform and cumber- some system, Dr. Wainio has by no means always found it best to follow it in the determination of specimens. The present writer has thus far followed the plan of the “ Monographia Cladoniarum ' Universalis ” in part, without reference to its objectionable features, but working on the supposition all the time that there is a real species, often with true varieties.

Oftentimes the study of our American forms has involved no difficulty, since species and vafieties stand out distinctly enough, in other instances no varieties being recognized in our area. So no difficulty will arise in the use of this series of papers, except perhaps in Cladonia fimbriata and Cladonia gracilis , our most difficult species, of which an adequate exposition has not yet appeared. Regarding the last species, further study of specimens indi- cates that our paper left too much under the specific description. Indeed, it now appears plainly enough that Wainio’s so-called variety dilatata is the prevailing form, standing at the centre of variation, and that it should stand for the species under the name Cladonia gracilis simply. Cladonia fim- briata is beyond us for the present, and we can offer no remedy. As to Cladonia furcata, it is not so certain whether the first variety, alpha, of Wainio’s system, should stand for the species or not, but this seems proba- ble. Regarding Cladonia verticillata , the variety evoluta would seem to be the species according to its position as assigned by Wainio, and the geographical distribution that he gives it as well. But so far as specimens seen from our territory are concerned, this is not the case, the plant plainly standing as a variety, and the form, with one or two exceptions, ranks as the species, as was given in our paper.

The January Bryologist was issued January 2d, 1906.

Concerning the present species, the variety alpha, cribosa of Wainio, is plainly the species, including nearly all specimens within our territory, and being the most common by far according to the distribution given it by Wainio. Also after looking through the species yet to be considered in this series of papers, it is apparent that there will be no difficulty in following the method inaugurated in the present paper, while the explanations given above regarding the species disposed of in previous papers of this series will clear up any difficulties, and enable workers to use this portion of the series in the same manner as the papers to follow.

The feeling that a change must be made has been growing as studies of the Cladonias have progressed, and defense for the procedure is ample. We may not be able often to ascertain elementary species by taxonomic methods, but we should at least make our systematic species conform as nearly as possible to the biological species. In so doing we must employ the parallel- istic method of considering both form and function in the selection of our spectific marks, when two morphological characters are equally prominent, giving more prominence to the one that is more useful. Then, too, if we are ever to approximate to true species, we must use some definite criterion and come to some agreement as to chief differentials. The statistical method proposed by Davenport and Blankinship, in a recent joint paper, seems to the writer to contain much of suggestion. We must not be content to base our views on a few herbarium specimens, but modes or centres of variation must be established in the field, by examining a multitude of specimens., then we must determine ranges of variation and degree of isolation for vari- ous forms encountered before deciding upon the limits of species and vari- eties. And nowhere is this sort of study more necessary than in the variable and plastic Cladonias , By this method, a worker may established species and varieties in the areas studied with some degree of mathematical cer- tainty. Then, by comparing results of such work in various regions, we may hope to establish world-wide conceptions of species of much greater value than those of the present time, discarding many of the “ historical types,” which are doubtless in many instances not true species, but varieties instead, and establishing true or “specific types.” De Vries has given instances in which systemists have found the elementary species, or at least true biologi- cal species, as opposed to compound conceptions, and we may hope by proper methods to approximate and often realize such results.

While the results to follow in this series of papers must rest upon the study of herbarium material very largely, no pains will be spared to make the species and varieties recognized conform as nearly to true biological species as can be done.

Cladonia cariosa (Ach.) Spreng. Linn Syst. Veg. 4: 272. 1827. Primary thallus persistent or replaced by new squamules, composed of irregularly laciniate, incised or crenate, concave, flat, involute or revolute, ascending or suberect, clustered or rarely scattered squamules, which are small or medium sized 1-6 mm. long and 1-5 mm. wide, pale sea-green above, varying toward olivaceous, whitish below or brownish toward the base, the cortex continuous

—23—

or more or less sorediate above and along the margin. Podetia arising from the surface or margin of the squamules, 5-30 mm. long and 1-4 mm. in diameter, subcyl- indrical or thickened toward the top, cupless and always termin- ated by apothecia, usually freely branching and sometimes even from the base, the branches spread- ing or more usually suberect, the sides commonly more or less fiss- ued or grooved, clustered or sub- solitary, usually suberect, the cor- tex areolate and the areoles scat- tered, rarely squamulose toward the base, pale sea-green or whitish, the decorticate portions betweeu the areoles whitish. Apothecia usually medium ^ized, 1-2 or even 4 mm. in diameter, clustered-conglomerate, frequently perforate, borne at the apices of the podetia, flat or becoming convex and immarginate, lighter or darker brown or possibly rarely reddish-brown. Hypothecium pale. Hymenium brownish above and pale or brownish below. -Paraphyses simple or rarely branched, thickened and brownish toward the apex. Asci clavate or cylin- drico-clavate,

On various soils and rarely on old woqd; in open or more or less shaded places. Distributed throughout North America, but much more com- mon toward the north, apparently being largely replaced toward the south by Cladonia mitrula, which will be considered in the next paper of this series. Examined by the writer from Massachusetts and Maine (Clara E. Cummings), South Carolina (H. A. Green, whose specimen was received under the name, C. caespiticia ), Tennessee (W. A. Calkins, and determined as C. subolescens Nyl.), Iowa (Bohumil Shimek and Bruce Fink), Minnesota (Bruce Fink), Colorado (Baker, Earle and Tracy, originally determined as C. symphycarpa, but changed by Wainio), California (H. E. Hasse), Wyom- ing (Avon Nelson), and several localities in British America (John Macoun). J. W. Eckfeldt lists from Greenland, T. A. Williams from the Black Hills, Mrs. Carolyn W. Harris from ’Montana, and Henry Willey from Illinois. Following Tuckerman’s Synopsis, Dr. Wainio’s distribution would add Oregon, New Mexico, and two or three arctic or subarctic stations.

A number of specimens have come to the writer’s herbarium from American localities, under the name Cladonia syinphycarpa Fr. , which was recognized as a distinct species by Tuckerman. Few of these specimens seen are in condition for determination, usually being without podetia, and though the squamules are frequently rather large, it seems probable that •Wainio is right in assigning such material to the present species.

—24 —

Cladonia cariosa corticata Wainio, Mon. Clad. Univ. 2: 53. 1894. The cortex subcontinuous or partly areolate with the areoles contiguous.

Examined from Indiana (L. M. Underwood) and from Tacoma Park, D. C. (T. A. Williams). Also a peculiar form from Maine (G. K. Merrill) doubt- less belongs here, though squamules are present at the tops of the podetia. The specimens seen are less branched than the usual forms of the species. Miss Clara E. Cummings also lists this variety from Alaska, and Dr. Wainio thinks that most of the forms given by Tuckerman under C. symphycarpa probably belongs here. Known also in Europe.

Cladonia cariosa squamulosa (Mull.) Wainio Mon. Clad. Univ. 2: 57. 1894. Squamules of the primary thallus somewhat elongated, and squam- ules present on the podetia. Cortex of podetia sometimes subcontinuous. Podetia sometimes simple.

A specimen sent by Prof. John Macoun, collected on the lower St. Law- rence, in Ontario, is this at least in part, squamules being quite numerous on some of the podetia, even to the top. Collected on humus over rocks. Known elsewhere only in Europe. Grinnell, Iowa.

MOSSES AT THE CONGRESS OF NEW ENGLAND NATURAL HISTORY SOCIETIES.

Cora H. Clarke.

In the middle of October, 1905, there was held in Boston a Congress of Natural History Societies, it being thought that it would benefit isolated societies in the different New England States to come together and learn what others are doing. There was an exhibition of specimens, contributed by the different organizations, open for three days, and on the last day, October 14th, was held a meeting at which there was a roll call of all the societies represented, and a delegate from each gave statistics as to its meetings, membership, and work. Many of the organizations studied but one section of Natural History, (Geology, Entomology, Ornithology or Botany). In all there were twenty-nine societies represented, with thirty-one exhibits by members of fourteen societies.

That the Congress was felt to be a success we may infer from the fact that a committee was appointed to arrange for a Federation of the Societies and for the holding of future meetings.

In the exhibition room were to be seen minerals, crystals, fossils, land snails, insects, bird skins, birds preserved in glass tubes, spiderwebs preserved between glass plates, inexpensive apparatus for collecting and preserving plants and insects, a book of photographs of tracks on sand, one of photo- praphs of wild flowers, ecological specimens of Phenogams, two sets of water- colors of fungi (hung on a net draped over one wall), also fungi fresh, fungi pressed, and fungi in bottles, pressed algae in books and on separate sheets, and finally, three exhibits of mosses and one of lichens. The lichens and the companion box of mosses was the work of our Sullivant Chapter member, Mrs. Dunham (who also showed a book of water-colored sketches of mosses). Her mosses are dried in tufts just as they grow, and the green foliage, golden setae, and brown capsules make a very pleasing color-combination. Each species stood in a small tray, and the trays were fitted into a large, flat box, with a lid. Mosses too tall for the box were laid on their sides. Her lichens were arranged in the same way, and of course these two boxes were but a sample of her whole Herbarium.

The next set of mosses to attract attention bore the name of Miss M. Edna Cherrington, though she disclaimed merit for them, and said they were the work of the whole Botany Class of the Teachers’ School of Science, and represented about a year’s study and excursions; many of them were naihed in the field. We noted that there were about one hundred species, nearly all from Eastern Massachusetts, some from Maine and New Hampshire: that the dates ran from April to November, 1904, including a few gathered in August, September, and October, 1905. These mosses were put up so as to occupy but little space, to be handled with perfect safety, examined with a magnifier on each side ; and could be taken out in an instant, to put under a high power, and return to the same envelope. These envelopes or slides are made of a

—26—

transparent, flexible material,* which in this case were 65 mm. X 75 mm., some larger sizes being used for the larger mosses; a pressed specimen of the moss, with a narrow label, being laid into the envelope, the front flap is slipped under a ridge, or fold, and everything is secure. A white card alternated with each transparent envelope, to form a background, and groups or families were tied together with cords passed through perforations at the base, so that the whole could be turned back and forth like the leaves of a book.

In the third set of mosses, the species were gummed on full-size herb arium sheets, this being the beginning of a Collection of Mosses to go to the Herbarium of the Massachusetts Horticultural Society, where it is no object to save space. A fruiting spray of Fontinalis Dale car lie a covered a whole sheet, but with the small, common species, like Dicranella hetero- malla , or Georgia pellucida, there were six or eight gatherings, from as many different months, to show seasonal change. Only about sixty species were as yet in this set. On many of the sheets a packet or envelope con- tained moss sprigs that could be taken out and examined.

We do not know how it was with the other exhibits, but we know that several pleasant introductions took place over the moss tables, followed by a correspondence which has been of advantage to all the parties concerned.

ADDITIONS TO THE BRYOPHYTE FLORA OF LONG ISLAND.

A. J. Grout.

Since the publication of Dr. Jelliffe’s “Flora of Long Island” in 1899, the following additions to the mosses and hepatics have been made by vari- ous collectors. Some of these were published in Torreya, April, 1902, and July, 1904. Unless otherwise credited the additions were made by the author.

This popular guide to the hepatics of France is very fully illustrated with figures showing the vegetative organs, stem and leaves, of the leafy hepatics, and the thallus and reproductive organs and spores of the thalloid forms, with magnifications of from one to fifty diameters; in the case of spores, three hundred diameters. The student with a leafy hepatic, unknown to him, starts with the first table of the Key and determines whether the specimen possesses succubous or incubous, entire, lobed or divided, etc. leaves, and places it in its family. The second part of the Key leads him to see if it possesses lobules or underleaves : to observe the shape and placing of the perianth, the root-hairs, etc., until the genus to which it

—29

belongs becomes apparent. Turning then to the third part of the Key, he observes the general aspects of the plant, color, texture, relations of the plant to substratum, cellular structure, habitat, etc., and with the accom- panying illustrations to aid finds its specific name. The thalloid liverworts are first examined with regard to the shape of the thallus, whether the dorsal side possesses stomata or gemmae, and whether there are scales on the ventral side: the shape and placing of the involucre, whether immersed, sessile or stipitate ; the shape of the opened capsule. The species of the family Ricciaceae are illustrated with outline drawings of the whole plant and with cross-sections of the thallus : while the species of the genus Fossombronia are determined by the characteristic markings and shape of the spores. There are two hundred and fourteen species given. So many of the French species are also inhabitants of America that this quarto should prove service- able to our own students of the Hepaticae.

GRIMMIA GLAUCA.— A NEW SPECIES OR A HYBRID.

John M. Holzinger.

Under this title Mr. Jules Cardot, in Rev. Bryol. 1905, p. 17, discusses and describes a sterile Grimmia found by him and Mr. Longuet near Charle- ville, in the Ardennes, north- ern France. On Aug. 23, 1905, the writer collected a sterile Grimmia on a ledge of lime rock left exposed by the gen- eral glacial mantle, and strewn with detached boulders of the same material, standing above the general level of the prairie, three miles due south of Lewis- ton, Winona County, Minn., about twenty miles from Win- ona, on the C. & N. W. Ry. The plants occurred quite abundantly, in loose cushions one to three inches in diame- ter. Their appearance sug- gested G. leucophaea, which was collected by the writer at Taylor’s Falls, on the eastern border of Minnesota, and in the valley of the Upper Min- nesota River, both at Montevideo and at Ortonville, on the western border o£ the State. But it was recognized, even in the field, that these plants were

From Cardot' s illustration in Revue Bryologique.

smaller than the known species. Microscopic examination proved them quite different, nor could they be referred to any described species, so far as there was time for comparison.

Under the circumstances it was deemed advisable to submit some of this material for critical study to Mr. H. N. Dixon, who on previous occasions had kindly taken the trouble to examine other Grimmias. Being recognized as an able and conservative bryologist, his judgment deserves to be put on record. He says of this plant:

“The leaf base and general appearance are precisely those of- G. leuco- phaea, from which I think it differs only, but very markedly, in the tapering points of the leaves. In fact it is almost identical with G. glauca Card., only differing in the larger, very rough hair points. It constitutes in fact^an intermediate stage between that plant and G. leucophaea . And some of your plants have the leaves slightly less tapering, and therefore still more like the latter plant. I would suggest that you send a specimen to M. Car- dot : I think he will be interested to see it. I am inclined to think that it somewhat confirms his suggestion that G. glauca may be a hybrid resulting from a crossing of which G. leucopheae is one parent.”

The writer accordingly sent both the letter, from which -the above ex- tract is taken, and some of the Grimmia in question to Mr. Cardot, who writes: “Your Grimmia is clearly my G. glauca, as Mr. Dixon thought.

It differs from the type from Charleville only by its longer, stouter, rougher hair point, and also by its less glaucous color. But there is no doubt about its being this plant. Is this a hybrid, or a species ? This question will prob- ably remain unanswered so long as the fruit is not found.”

Sterile Grimmias are at best difficult to determine, usually requiring the examination of leaf sections, both near the base and apex. In the case of the moss in question, it has, therefore, seemed advisable to make accessible to all interested bryologists the independent judgment of the two students above quoted, both well known for their ability and achievements.

It appears that neither in Mr. Dixon’s nor Mr. Cardot’s judgment there is so far decisive evidence that this is either a good species or a hybrid, unless the recognized variation, in the Minnesota plant, of the stouter and frequently longer hair point may be held to lead to the view that it really is a hybrid. In the face of this uncertainty the writer ventures to suggest that the geographical distribution of the plant — its occurrence in two isolated areas, one in Northern France, the other in the Upper Mississippi basin, on a knoll in Southeastern Minnesota— tends to argue for its value as a good species. It should be recalled, in this connection, that Winona County lies in the northwest portion of the Driftless Area. This Area, as the writer has shown in a former note, harbors Grimmia teretinervis Limpr., not known again till one reaches the Austrian Alps, Claytonia Chamissoi Ledeb., a thousand miles to the east, and 4000-5000 feet below its normal home in the Rocky Mountains, and other plants of similar remarkable distribution. The addition of Grimmia glauca Card, to this list of plants marooned, as it were in the Driftless Area, in the penumbra of which lies Winona County, is thus

—3i —

a matter of interest both geographical and botanical. It also constitutes an' argument for the specific value of Mr. Cardot’s plant, unless it be admitted that a hybrid may exist, and persist, for several thousand, even several times ten thousand years, in such widely separated areas. And further, the sub- stratum for G. leucophaea, so far as the writer’s observations go, is trap and granitic rocks ; G. glauca occurs here on the sedimentary dolomitic lime- stone of Lower Silurian age. Nor yet could hybridization have taken place, at least so far as the American station goes to show: the knoll near Lewis- ton, E. Minn., is over a hundred miles from either of the Minnesota stations known to the writer. Whether the degree of isolation and substratum, of this plant of the French station, agrees with the above data, it will be inter- esting to learn from Mr. Cardot.

Following is Mr. Cardot’s description translated from Rev. Bryol, 1905, pp. 17-18:

“Plants forming dense tufts or cushions, not cohering, of a glaucous- green color when dry. of a lively green when moist. Stems simple or divided from the base, 5-10 mm. long. Leaves straight, closely imbricated when dry, lanceolate, long, and gradually tapering-acuminate nearly from the base, quite concave, channelled above, terminating in a short-toothed hair ; about 2 mm, long, .6-75 mm. wide : borders plane, quite entire ; blade in all the upper portion, except on the borders, formed of two layers of small very chlorophyllose cells rounded or subhexagonal seen in a face view, but higher than wide seen in cross section ; cells of the basilar portion in a single layer: at the angles are found numerous transversely enlarged cells, disposed in regular rows, becoming then square and passing gradually into the small cells of the upper leaf part; costa depressed, formed at the base in a cross section of two layers of the epidermal element analogous to the cells of the blade, between which is observed a layer, more or less developed, of smaller cells with thicker walls; the costa becomes indistinct towards the apex, where it is ordinarily reduced to a single cell lying between the two halves of the blade.

“ By its leaves with plane margin, by its tissue, and by the structure of the costa, this moss evidently leans strongly toward G. leucophaea. But it is easy to distinguish the plant by the shape of the leaves; while in G. leucophaea they remain quite broad to near the apex, where they are abruptly narrowed into a very long hair, in G. glauca they are narrowed gradually and end in an elongated apex overtopped by a short hair. This last character, it is true, is not of great value, for forms of G. leucophaea with short hair points are quite frequently met with ; but the form of the upper part of the leaf is quite distinctive, and does not permit of confusing G. glauca with G. leucophaea .” Winona, Minn.

To aid in the clearer understanding of the distribution of this species, it may be of interest to note its occurrence at Middletown, Rhode Island. Dur- ing September, 1905, 1 collected several specimens, and in November received, through the kindness of Mr. Edward Sturtevant, several more. It grows commonly on the Red Cedar ( funiperus Virginiana), the tree which mainly comprises the Paradise Woods, which back the Second Beach sand dunes.

My determination of the species was corroberated by Dr. W. G. Farlow, .after careful comparison with specimens in the Cryptogamic Herbarium of Harvard University, where, at his request, a specimen was placed, as the Herbarium contained no Rhode Island specimens. % m

Willey recorded in 1892 the presence of Ramalina rigida Pers. in the region of New Bedford, which is some twenty miles to the northeast.

ENCALYPTA PROCERA.— A CORRECTION.

The punctuation or better perhaps the lack of it in my copy of Die Natiirlischen Pflanzenfamilien led me in the article on Encalypta procera Bruch, in the November, 1905, Bryologist, to ascribe to Brotherusan opinion that he evidently does not hold, namely, that E. Selwini Aust. is identical with E. procera Bruch. In a paragraph in which both are mentioned the final sentence on E. procera is not separated from the one beginning with “ E. Selwini ” by any mark of punctuation, which led me rather hastily to infer that they were one species. A closer attention to the custom of placing a synonym in a parenthesis after the name of the species with which it is identified would have prevented the mistake, even with the faulty reading. I am indebted to Prof. Holzinger for calling my attention to the error.

AUSTRALIAN MOSSES.

Some Locality Pictures.

Rev. W. Walter Watts.

The Editor has suggested to me that brief “pen pictures” of Australian Moss localities might interest readers of the Bryologist; and with that object in view, and with the added purpose of assisting the cause of Australian bryology, I shall be glad to send an occasional paper to a publication that has interest, not only in America and Europe, but even in these far-off Southern lands. «

I begin with the district in which I am at present located, the district of Young, in New South Wales, — not my first, but my latest, bryological love.

The town of Young lies a few miles northwest of the main Southern line from Sydney to Melbourne. “As the crow flies” it is about 150 miles from the coast, 200 miles from Sidney, and stands 1400-1500 feet above sea-level. It was formerly an important gold field, and the vincinity of old watercourses has been honey-combed by the alluvial miner. The district is diversified with hill and hollow. Our chief products are wool and wheat, — and rabbits. The climate is healthy. Such rains as we get fall mainly in the Winter; the Summer is usually hot and dry. The temperature ranges from a few degrees >o£ frost in Winter, bringing us very rarely a touch of snow, up to as much as 1 15-120 degrees in the middle of Summer. Our mosses are mostly denizens •of rock and ground, and must be looked for during the Winter and the early Spring, say July to October.

Outcrops of granite occur in all parts of the district. In some directions they develop into high rocky hills: humbler outcrops, with the grass growing to their base, are a distinguishing feature on every hand. Where the land has not been cleared, the characteristic “gum” tree lends picturesqueness to the view.

I propose a visit to one of these granite outcrops, choosing a spot where the rocks, worn with the weather of unknown centuries, are flanked by open country that stretches down to rich alluvial flats. It is the month of August, when the moss-fruits are rapidly hastening to maturity, some of them already displaying their open capsules, while others still retain the veil.

Examining first the rocks themselves, we find that the most obtrusive species are Taylor’s Grimmia cygnicollis , and G. leiocarpa. ‘ The* first of these, Mitten identified with G. pulvinata, var. obtusa (Brid.), and Brotherus, in Bryales, follows him. Wilson regarded G. leiocarpa, Tayl., as a var. of G. leucophaea, Grev. Brotherus agrees, but merges G. leucophaeain G. campes- tris, Burch. I cannot yet throw off the familiar names. We shall also find, perhaps in large quantities, Hedwigia albicans (Web.) Lindb. (H. ciliata, Ehrh.). C. Mueller regarded the Australian moss as a new species, H. microcyathea, C. M. Hedwigidium imberbe , Sm., is also here, but without .any trace of fruit: Pseudoleskea calochlora , C. M.. and Tor tula princeps , DeNot. If we follow Brotherus in his conclusions regarding the two Grim- mias, we shall be struck with the remarkably northern character of this rock

-35-

flora. T.. princeps, though sometimes growing on the bare rock, prefers hollows or crevices where a little soil has collected.

Still keeping to the rocks, we may find in obscure corners, sheltered and half-hidden by some overhanging projection, the unique and beautiful Fab- ronia Tayloriana , Hamp., perhaps in the form foliis integris , Broth. Fab- ronia Scottiae , C. M., may also be found, a species wide-spread in N. S. W., and which was first collected by Miss Scott, now Mrs. Forde, a lady who in her earlier years spent much time and showed much skill in making drawings of many of our Australian mosses. In the crevices of the rocks we shall find a few species of Bryum , but, in the absence of fruit, for they are mostly sterile, some of them are not yet determinable. We may note, however, Bm subatropiirpureum, C. M., B. peraristatum , C. M., ( a beautiful species ), B. erythropyxis , C. M., and perhaps B. pachytheca, C, M., which last is exceedingly plentiful throughout the district, growing mostly upon the ground, where, mixed with Funaria hygrometrica, it forms a perfect picture, with its thick, dark-red, hanging capsules, a typical Doliolidium.

Turning now to the ground at the base of the rocks, generally damp and shaded, we shall find probably specimens of Breutelia affinis ( Hook. ) Mitt. ;

B . commutata ( Hamp.) Par. : Bartramia papillata, H. f. W. ; B. gymno- stoma, Broth,, sp. nov. , in appearance very much like B. papillata, but dis- tinguished, as the name implies, by its want of a peristome: Bryum calodic- tyon, Broth., sp. nov., a most distinctive and dainty species of the Argyro- bryum group: Triquetrella papillata ( H. f. W. ): perhaps also Tr. albicus- pes . Broth., sp. nov,: Weisia flavipes , H. f. W. : Hymenostomum Sullivani,

C. M. (rarely): Encalypta tasmanica, Hamp. etC. M.; Funaria hygromet- rica (L)Sibbth., var. sphaerocarpa (M;assp. ): F. tasmanica , Hamp., a fine species with very distinctive characters: F. ( Entosthodon ) apophysata (Tayl.): F ( Entosth.) aristata , Broth., very similar to the preceding, but differing in its percurrent nerve: Fissidens elamellosus , Hamp. et C. M.: F. macrodus , Hamp.: the inevitable Ceratodon purpureus\ possibly Campy l- opus Woollsii, C. M., Ditrichum affine , C.M., and two or three species of Pottiaceae which anticipate those ,growing on the open ground that slopes down to the richer flat country.

Leaving then the rocks, we turn our attention to the hard ground, where the grass grows scantily and bare spaces of water-washed soil provide treas- ure spots for the bryologist. If one has been previously accustomed to the luxuriating coastal mosses, especially the fine, tree-loving, sub-tropical forms of the Northern Rivers, he will simply revel in the rarities here displayed. Dignity he will throw to the winds; he will not even go down upon his hands and knees: he will lie flat upon the ground, and, lens in hand, forget the world and its cares in the delighted contemplation of the rich garden of Nature spread out before him. The Pottiaceae are particularly in evidence, as they are throughout the district. Probably Tor tula atrovirens (Sm.), will be the first thing to greet our eye; then Barbula calycina Schwgr., and per- haps B. torquata , Tayl. Before turning to the minuter mosses that consti- tute the special attraction of the spot, we take note of Bryum pachytheca

—36—

and the Entosthodons already mentioned. Then the tiny capsules of Pottia brachyodus , Hamp., or P. brevicaulis ( Tayl. ), or even both of them. We shall not have far to look for Acaulon Sullivani, C. M.: while, growing with it or in separate clusters, we may see Acaulon robustum , Broth., sp. nov., easily distinguished by its larger and stronger form. Aslomum cy lindricum, Tayl., and P leuridium nervosum (Hook.), are almost sure to be there, and, more rarely, P leuridium gracilentum, Mitt, and Eccre?nidium pulchellum, H. f. W. But, most attractive of all, we shall see the lovely Gig a sp* rm u m repens (Hook), with its large white transparent perichaetial leaves, and Goniomitrium enerve , Hook, et Wils.. with its distinctive calyptra; possibly G. acuminatum. Hook, et Wils., may also be there, as it occurs (rarely) in the district. Then, if we are fortunate in our choice of a spot, we may see a rarity indeed: Tr achy car pidium Novae Valesiae, Broth., sp. nov. At first glance we may mistake it for a Goniomitrium: but we shall readily notice the ab- sence of the angles in the veil, and the long Archidium-like leaves that sur- round the fruit. This species is the second of the new genus that Brotherus, in Bryales, founded upon a New Caledonian moss. It has proved to be wide- spread in the district. I collected it only last week in the Cowra district, nearly fifty miles from here. You may be fortunate enough to find in this spot, though they are rare and have only been found by me occasionally, Barbula acrophylla , C. M., B. australasiae (Hook, et Grev. ), B. chlorotricha (Broth, et Geh. Par., B. austro-unguiculata , C. M., and Torticla evanes-

cens, Broth., sp. nov.

Coming down to the fiat country, if we take a fallow paddock, we shall find over again many of the ground mosses already discovered, but probably in finer condition than on the hill- slopes, especially the Acaulons and the Pleuridiums. PI. gracilentum seems to prefer the lower, damper habitat. We may find too, probably by accident if we are not looking specially for it, the minutest of all the species of this district; Ephemerum cristatum (H. f. W.) a truly beautiful moss, of which I have collected good material in fruit. Bry- um argenteum, var. niveum, will be found plentifully, and possibly the rare Funaria pilifera , Broth.

Cutting its way through this flat country we may find a creek so-called; and among the grass of its banks we may find, in addition to many of the foregoing, Hypnum patulum, Hamp., and H. tenuifolium, H. f. W., often in association with Breutelia commutata. Close by we may find some old, partially filled mining shafts, and on their damp shady banks we shall dis- cover such species as Bryum calodictyon , Broth, the Firidentes, Fungriae, Bartramiae, etc. already mentioned, as well as Brachythecium rutabulum, Stereodon cupressiformis and a Philonotis not yet determined.

NOTES ON NOMENCLATURE VI.

Elizabeth G. Britton.

The most notable advance made at the Botanical Congress in Vienna (1905) was the unanimous adoption of the priority of the oldest specific name, and the total extinction of the varietal name as a factor in priority. The oldest generic name and the determination of the type species for every genus has not yet been adopted, but we hope that at the next Congress, five years hence, the committee on the Nomenclature of Cryptogams will not only see the importance of this rule, but also that the subgeneric name as a factor in priority will also become extinct.

M. Cardot, Prof. Brotherus and myself are members of the commission to decide on questions of nomenclature for the mosses at the next Botanical Congress at Brussels, and it is hoped that some logical agreement will be reached. M. Cardot is still following the Paris Code of 1867, Section 58, and is giving the oldest subgeneric name priority over a later generic name, but he is not doing this consistently for, if he adopts Cryphceadelphus (C. M.) he should also adopt Aptychus of the same author. In Engler & Prantl, Pflanzenfamilien, Prof. Brotherus has also adopted two changes of sub- generic to generic names, and he has called my attention to a duplication of names which has occurred, each of us coming to the same conclusion indivi- dually and separating, almost simultaneously, the genus Alsia into two genera.

In the following notes, all changes affecting North American mosses are listed and illustrations of two genera, new to the United States, are repro- duced, from parts 222 and 223 of Engler and Prantl Pflanzenfamilien, which were delayed in reaching us.

Erpodium (Brid. ) C. M. Bot. Zeit. I: 774. 1843.

In the Bulletin of the Torrey Botanical Club for May, 1905, I have called attention to the error in citing Bridel as the author of this generic name. He printed it as a subgenus of Anoectanginm, and it was Carl Muller who raised it to generic rank. E. Doming ense (Brid.) C. M., is the type species from Santo Domingo, and it has also been collected in Jamaica and Porto Rico. E. Cubense , E. G. Britt, from Cuba, E. Pringlei , E. G. Britt, from Mexico, and E. biseriatum (Aust.) Aust. from Georgia, have been described by me. (Bull. T. B. C. 3 2:266, 1905, and Bryologist 8:71, 1905). Dr. Max Fleischer has examined the type of E. diver sifo limn, C. M., at Berlin, and thinks it is referable to E. Domingense. E. Paraguense Besch. has been described. (Mem. Soc. Nat. de Cherbourg 21 1265, 1877.)

— 39 —

from recent investigations it becomes evident that they are only aquatic forms of C. Americanum and should have been given the name that they were distributed under by Austin in his Musci Appalachiani No. 289, C. Americanum var. fiuitans (p. 49. 1876).

This is another instance of the replacing of a generic by a subgeneric name. P. ruthenicwn (Weinm.) Kindb. is our West Coast species found also in Asia and Japan.

Cryphzea Ravenellii Aust. has been referred by Kindberg (Br. Eu. & N. A. 1:7. 1897) to Forsstroemia and Brotherus has accepted this opinion. I have already stated (Bull. T. B. C. 3 2:263.1905) that Austin was quite right in placing it in Cryphcea.

Dendropogonella E. G. Britton, new name.

Dendropogon Sch. Bot. Zeit. 1:377.1843. not Raf. Neogenyt. 3:1825.

As Rafinesque’s genus has been taken up recently by Dr. Small for Tillandsia usneoides L. (Flora S. E. United States 244.1903.) Schimper’s name succumbs to the fate which seems to await a homonymn, hence I have added a syllable in order to distinguish the genus of the true mosses from our common “ Florida Moss.” Only one species is known from Mexico and the Island of St. Thomas, Dendropogonella rufescens (Sch.) E. G. B.

Leucodon doming ensis Mitt. Journ. Linn. Soc. 12:409.1869.

It is interesting to note that on page 751, Brotherus says that this is un- doubtedly a distinct genus, but he failed to name it, or to adopt its oldest specific name. It has been collected at five stations in Florida, and is found in the West Indies and in the northern part of South America.

This species has also been collected by Mr. R. S. Williams in Bolivia, and was referred to Acrocryphcea , from which it differs in the elongated cells of the upper part of the leaves and the much more prominent basal differentia- tion of the cells.

Antitrichia Brid. Sect. I. Macouniella Kindb. p. 756.

This is the way that Brotherus disposes of Macouniella. Cardot has called my attention to the fact that A. Calif ornica var. flagellifera. E. G. Britt. Bull. T. B. C. 32:266.1905, is unknown to him. It is evidently a mis- take for Alsia Calif ornica flagellifera R. & C.

A. Calif ornica, and the variety flagellifera R. & C., are listed. Alsia longipes Sull is said to be a Thamnium. This species has recently been included in the following genus by me. (Bull. T. B. C. 3 2:265.1905.)

D. abietina (Hook.) E. G. Britt, and D. circinnata (Sull.) E. G. Britt, have been included in Alsia Sull. & Groutia Broth ; they seem to me to be sufficiently distinct and to include Alsia Macounii Kindb.

These specimens from Lake Pond d’Oreille, Idaho, collected by J. B. Leiberg, are the finest that have ever been collected of this species. The accompanying photograph (Plate II) shows the size on the herbarium sheet on which they are mounted.

AUSTRALIAN MOSSES— SOME LOCALITY PICTURES

Rev. W. Walter Watts,

(Concluded)

This may be allowed to end our trip. But, to complete my records for the district, I must add one or two notes.

Some parts of the district produce native pine trees ; and, so far, these are the only bush trees on which I have found any trace of mosses. The species are Tortula vesiculosa , C. M., a species so-named on account of the vesiculose character of the green brood-bodies that abound on the nerve of the leaf; and Tortula Baileyi , Broth., which produces elongated brood bodies, very beautiful to see, at the tip of the stem. These two mosses occur on the poplars planted in the town of Young T. vesiculosa most plentifully.

At one spot 12 miles from Young, I collected Bryum tasmanicum, f. seta breviore, Broth. From Weedallion Mountain, 30 m. from Young, comes Bryum sublaevigatum, Broth., sp. nov. Poly trichum juniperinum , Willd. > is not uncommon. At Grenfell, 32 m. away, on the sides of an excavation of rock, I collected Dawsonia longiseta, Hamp. ; on the Wedden Mountain, a locality which I intend to explore later, Pohlia nutans (Schreb.) Lindb.

Finally, at KOorawatha, some 25 m. from Young, in a deep valley among the mountains, I collected Stereodon cupressiformis (L); Mielichhoferia Forsythi , Broth.; Mielichhoferia turgens , Broth., sp. nov.: Grimmia apo- carpa; Racopilum convolutaceum , C. M.: and the interesting Pilonotis remotif olia, H. f. W. , a moss which has so much the appearance of a Thuid- ium that, when first found, it was named Hyf7ium (Taman's cella ) scabri- folium. Sullivant, who first received the fruit, named it Bartramia exigua, and that name is retained by C. M. in his Genera Muscorum. At one time H. et W. called it P hilonotis appressa; but the name was subsequently abandoned as inappropriate to the female plant. Brotherus, in Bryales, gives precedence to Ph. Scabrifolia (H. f. W.).

Other species, especially of Bottiaceae and Bryaceae, are certain to be found in this district; but this paper will give a good general view, I trust, of the Moss Flora of this part of N. S. Wales. I may add that for many determinations I am indebted to S. Brotherus.

“WHEN DOCTORS DISAGREE.”

(Before reading this note, please turn to the Bryologist 7:78. Sept. 1894, and read carefully the article under this caption, noting dates mentioned. )

In my herbarium are two packets of mosses labeled as follows :

Thelia Lescurii Sulliv., Sandy soil, Rockville, L. I., Dec. 1, 1899. Coll. A. J. G., type of P. Groutii, No. 196, N. Am. Musci Pleurocarpi. De- pression in base of chestnut tree. Hempstead, L. Id., Dec. 1, 1899.

In my collection of letters from Mrs. Britton, I find one from which the following is an extract.

“Bedford Park, Dec. 4, 1899.

“Your packet of mosses is received. Thelia Lescurii occurs on West Rock, at New Haven, where Prof. Eaton collected it, and I think it has been found at other places in New England, but I should have to look this up at the herbarium. The Plagiothecium you send is a pretty little species, con- spicuous for its resemblance to the laxer forms of H. recurvans , which it resembles in its small capsules, which are horizontal, and its recurved leaves. I think it will go under one of the varieties of H. denticulatum, either laetum or aptychus. Send it to Dixon for an opinion. It answers pretty well to No. 361, Aust. Musci App., which was distributed as P. dent. var. pusillum , which he says grows on the roots of trees in dry woods - - - - - .

“I shall be writing to Dixon soon about another matter, and will send this to him, as I should like his opinion on them.”

The italics are mine.' I may add that at this date, the Dec. 1899 col- lection of Thelia Lescurii was the first and only collection of the species I had ever made.

I will draw no inferences, for I feel that my readers will be amply able to do that for themselves. A. J. Grout.

BRYOLOGICAL NOTES

A. J. Grout.

Pogonatum brachyphyllum Michx. None of the available descriptions of this species allude to the great difference between the capsules of this species and those of P. brevicaule. The capsules of the latter are erect and almost or quite symmetric, while those of P. brachyphyllum when fresh are inclined about as much as those of P. alpinum, and are oblong-ovoid and strongly unsymmetric. This difference is much less apparent in herbarium speci- mens.

Tetraplodon australis Sulliv. & Lesq. Some specimens of this species sent me from Thomasville, Ga., by Mrs. A. P. Taylor, were so unlike any of the descriptions, that I at first thought they must belong to a different species and perhaps a different genus. The leaves were entire and as long, and slenderly acuminate as in T. angustatus ; the columella was distinctly exserted, the teeth reflexed, and the hypophysis so reduced as to make only a moderate sized neck. An examination of Sullivant & Lesq. Musci Boreali- Americani, Edition i, No. 15 1, in the Columbia University Herbarium revealed at least one capsule with an exserted columella and at least one capsule in which the hypophysis is as reduced as in the Thomasville specimens. No. 227 of the Second Edition has many exserted columellae and many capsules with small hypophyses, but has leaves as strongly serrate as those figured in the leones. An examination of the other specimens in the combined collections of Columbia University and the New York Botanical Gardens showed that the small hypophysis and exserted columella are common variations found in- termingled with plants like those figured by Sullivant. The presence of nearly entire leaves in rare cases is noted in the Manual. The teeth seem to be normally reflexed in perfectly ripened capsules. These observations indi- cate that the speices is an exceedingly variable one, intermediate between Tetraplodon and Tayloria, and suggest that it may perhaps be better referred to the latter. More exhaustive knowledge of the two genera than I at present possess is needed to decide this.

Anacamptodon splachnoides (Frol.) Brid. Specimens of Anacamptodon sent by Mrs. A. P. Taylor, from Thomasville, Ga., have the costa somewhat thinner and almost percurrent ; the seta longer and the capsule slightly larger than in the ordinary run of specimens : the operculum is scarcely more than conic in most of the specimens. Dr. Best suggests that it may be a ;trans- ition form between A. splachnoides and A . Cubensis Sulliv. which is based on Wright’s No. 66. A. Cubensis is said to be closely related to A. splach- noides, but smaller with a percurrent costa and a conic-acute operculum. (See Jour. Linn. Soc. 12:540). I should not be surprised to find that the Georgia moss is identical with A. Cubensis. Until this can be definitely settled, I propose that this form be known as Anacamptodon splachnoides Tylorsae.

Brachythecium Noveboracense Grout. A continued study of this species in the field has shown that this species is a derivative of B. rivulare, and is common in Long Island swamps. The gametophyte characters given in the original description (Bryologist 3: 36. 1900) are generally characteristic of the species but the capsules figured there were abnormally straight, and the seta is less papillose than in most specimens.

Burnettia fabrofolia n. sp.

Closely resembling B. subcapillata, but with branch leaves broadly lanceolate to ovate-lanceolate, much more gradually narrowed to a longer and more slender acumination: median leaf cells about 1/5 larger, 60-80 x Sju, quadrate alar cells fewer and larger, about 16 ju wide; capsule less gibbous and less plainly narrowed at the mouth.

On bark at roots of trees, near Thomasville, Ga. Coll, by Mrs. A. P. Taylor, Oct. 20, 1905. Type in the herbarium of the author. Co-type in the Herbarium of Columbia University.

The fruiting plants were few and closely intermingled with Raphidos- tegium adnatum. In order that perfect capsules might be left with the type as few peristomes as possible were studied. One of these seemed to have the teeth united at base in pairs. I am greatly indebted to Dr. G. N. Best for assistance in the study of this plant, although he is in no way responsible for this publication. He says that this plant has the capsules of Homalothe- ciella , and the leaves of Fabronia. No calyptra were found.

As most of the available descriptions of B. subcapillata are inadequate, a fairly complete account of that species is appended to enable students to distinguish between the two.

SOME LICHENS OF MT. WATATIC, MASSACHUSETTS.

Reginald Heber Howe, Jr.

No one thing has further advanced the knowledge of the distribution of birds than a very general publication of local lists during the past decade. Less than a dozen titles would, I think, complete the bibliography of such New England lists of Lichens. It is for this reason that the present list appears, and it is hoped that it will be but the first of many to follow. The words “southern,” “eastern,” as applied to North America, now answer for the distribution of many species, and these terms might be made more specific if authentic local lists from many points were accessible.

May I be permitted, though a comparatively recent and yet ignorant, student of Lichens, to speak humbly of Lichenology. I entered its field from that of Ornithology, and examined its state with a somewhat trained scientific mind, and nullius addictus jur are in verba magistri. At once I felt, as a very sane lichenist put it to me recently, that unfortunately the study of Lichens has a peculiar magnetism for the posing scientific “crank.’’ Secondly that no manual existed for the army of field students, often “unscientific,” as the expression is, but nevertheless often the ones, from their very numbers, to contribute much of real value, on question of distribu- tion, habitat, etc., not to say as collectors. Thirdly, the marked tendency toward verbosity and overdone scientific descriptions found throughout Lichenological literature, and lastly the unprecedented use of tri-nomials and quadri-nomials for mere contingent phases.

These statements will, I know, be considered by some to reflect upon my ignorance as a Lichenist, yet I feel somewhat strengthened to withstand comment, from the fact that my views are those also of one of the recognized and truly scientific Lichenologists of New England.

Mt. Watatic is one of the highest of the group of foothills, known as the Peterboro Hills. It occupies a position in the northwestern-most corner of Middlesex County, a little over a mile from the New Hampshire line, in the township of Ashby. Its altitude is about 1875 feet. Spruce covers its north-

-47-

west slopes to nearly the summit, while its southwest side is comprised of rough pastures and stump-lands. The double summit is bare and rocky for a few square rods. The Lichens enumerated below were collected on one ascent to its summit, December 28, 1905.

BOOK NOTICES AND REVIEWS

Dr. Albert Schneider has published two books on Lichens, one a “Text- Book of Lichenology,” published by Willard N. Clute & Co., Binghamton, N. Y., is the standard work, and contains 76 full page plates. The more elementary work, “A Guide to the Study of Lichens,” is published by Knight & Millet, Boston, Mass.

Reginald Heber Howe and Marion Appleton Howe, have begun the publication of “Common and Conspicuous Lichens of New England.” The work is to appear in parts, and part second has just been received. The authors intend that the work shall be “A Field Book For Beginners,” and the two parts already published give assurance that it will serve its purpose well. However, we must warn the beginner against supposing that he can ever get a comprehensive knowledge of the Lichenes , without the aid of a microscope, as many of the plants can not be determined by the best lichenist, without careful microscoptic study. The marginal illustrations are good, and will, with the aid of the short, but well worded diagnoses, prove very helpful to the beginner. The half tones are by no means all that could be desired, but we will hope for better ones in the future issues. The work will surely help teachers and others beginning to study lichens, and aid them in becoming acquainted with the more conspicuous species.

“Lichenology for Beginners” by Prof. Sargent, which was printed in The Bryologist during 1905, has been issued as a pamphlet and may be obtained by sending fifty cents to the Publishers, The Harvard Co-operative Society, Cambridge, Mass.

MEETING OF THE SULLIVANT MOSS CHAPTER.

A meeting of the Sullivant Moss Chapter will be held in New York, this coming December, in connection with the annual meeting of the American Association for the Advancement of Science.

In addition to a programme of papers on subjects of interest to the chapter, it is desired to have as complete a representation as is possible of the works of the chapter members. To this end all members are urged to contribute material for exhibition purposes. Drawings, paintings, collections of mosses, lichens or hepatics from various localties, methods of mounting specimens, rare or interesting species, anything, in fact, pertaining to the chapter work will be very acceptable. It is especially urged that members prepare lists of the mosses, lichens and hepatics growing in their respective localties, in order to furnish a basis for a more accurate knowledge of the distribution of these plants. If in addition to these lists, actual specimens for verification can be contributed, the value of the work will be greatly increased.

.-This notice is published early in order that all may have due notice, and that all may be watching during the coming summer for useful material for the exhibit. The officers of the society will be very glad to answer questions relative to the meeting. Further information will be given later in the Bryoi.ogist. Edward B. Chamberlain, President.

In sending for the “ Offerings,” judgment should be exercised as to whether to send stamps or an addressed envelope. As a general rule, the mosses and many of the hepatics would carry as well in a good sized envel- ope, but the lichens require a box or straw boards in order not to be broken. It has been suggested by one careful member to moisten the lichen slightly before mailing. A postal card acknowledging receipt is no more than com- mon courtesy.

The Curator for the cryptogamic section of the Herbarium Boissier at Chambesy, near Geneva, Switzerland, desires to exchange mosses and hepatics with American and Canadian Bryologists. The Herbarium Boissier has a large collection of duplicates, mostly European with some exotics. For further particulars address Monsieur G. Colomb-Duplan, Les Tordils, Ouchy-Lausanne, Switzerland.

RAMAL1NA RIGID A IIN MASSACHUSETTS.

Since I published my note on this species (Bryologist, Vol. IX., No. 2, Mar. 1906. p. 32.) I have had some ample and more typical6 specimens sent me from the Island of Martha’s Vineyard where it grows with Usnea b. ceratinaon Juniperus. In Decades of North American Lichens, Cummings, Williams and Seymour, No. 199, I find specimens from Brewster, Massa- chusetts, collected on November 10, 1904, by L. A. Crocker. Ramalina rigida Pers. seems to have a New England range almost identical with the Seaside Sparrow (Ammodramus maritimns ), an Upper Austral species, and the plant may evidently be looked for over the entire Cape and south shore region of Massachusetts, as well as along the coasts of Rhode Island and Connecticut.

NOTES ON THE LIFE HISTORY OF THE MNIUMS.

Phebe M. Towle.

The study of the life history of some of the mosses which was begun in the spring of 1905, has been continued during the past year. The observa- tions for 1903 upon the Hair-caps gave for Polytrichmn commune and P. juniperinum the time of maturing of antheridia and archegonia and their contents in April, and the time of the maturing of the sporophytes in August of the following year, a period of about sixteen 'months. The observations of 1904 upon Catherinea undulata gave the time of maturity of the- anther- idia and archegonia and their contents in May, and the time of the maturity of the sporophytes in the following March and April, a period of about eleven months.

The observations for 1905 have been chiefly upon the Mniums and upon these we have made only a good beginning. There are only three Mniums on this list and the work on one of these is unsatisfactory. It is hoped that careful observation in 1906 may make this clear and complete the list.

Mnium sylvaticum grows in shady places, in the woods near the brooks, and in damp, rocky places. It is a beautiful bright green moss in early spring. On April 13th, the sporophytes were shedding their spores. On June 20th, M. sylvaticum heads which are bisexual were examined. Neither antheridia nor archegonia when undisturbed were open, but disturbed an- theridia discharged sperm mother cells. About three weeks later, July 14th, in one head, two archegonia had grown to twice the height of the others.

— 55

A second head had one archegonia twice the height of the others. The bases of these taller ones were light green, evidently owing to the development of the new sporophyte within. On August 9th, the sporophytes showed with a hand-lens, and on Sept. 22d they could be plainly seen with the unaided eye, being about % inch high. On Nov. 5th, the sporophytes were a little taller, averaging about inches high. The stems were reddish brown. The calyptra came off easily and the part underneath the calyptra was bright green. By Nov. 28th, they had grown to yz inches high, but had not other- wise changed in appearance.

While the observations for the season were not sufficiently full to justifiy final conclusions on all points, it was found that the matering of the sperm and egg cells is between June 20th and July 14th or better, during the latter part of June, for the sporophytes had begun to grow by July 14th, and that the sporophytes were discharging spores during the latter half of April. So we may conclnde'that in Mnium sylvaticum the time from the maturity of the antheridia and archegonia and their contents to the maturity of the sporophytes is about ten months.

Mnium affine ciliare grows in nearly the same places as M. sylvaticum. The shedding of the spores from the sporophytes of Mnium affine ciliare was recorded for May 16th. On May 23d antheridia were open and dis- charging sperm mother cells. The motile sperm cells were very active. This is a dioicous moss. On June 5th, four archegonia of one tuft were open, and on June 20th in one archegonial head eight archegonia were dark, dead, five were open and two were not open but bright. On July 14th, in one archegonial head all but two were dark. In another all but one were dark. These living ones were about three times as tall as the dead ones. They were bright green nearly to the tip. These were the new sporophyte plants. On September 22d the new sporophytes could be plainly seen. Nov. 5th they were % inches high. The stems were reddish brown to the calpytra underneath which they were bright green. During November the moss plants put forth a vigorous growth of stem and leaf.

From the season’s observations Mniuin affine ciliarZ appears to begin to mature its sperm and egg cells in the latter part of May, continuing the work through most of June, and the sporophyte maturity comes during the following May. So for M. affi,ne ciliare the time from the maturity of the antheridia and archegonia and their contents to the maturity of the sporo- phytes is about eleven months.

Mnium Drummondii. — Closely associated with M. affine in locality, and closely resembling it in appearance was a bisexual moss which I took to be M. Drummondii. This moss was shedding spores on May 16th, as was M. affine. On May 30th in one head, showing both archegonia and anther- idia two archegonia were open. No antheridia were open. On June 1st, another head was examined, a few archegonia were open but more were closed. All the antheridia were closed. On August 9th, four little sporo phytes were seen with the aid of a hand-lens in one head of M. Drummondii.

I have no later observations on this moss. But these observations indi-

-56-

cate the fruiting seasons to be the same as in M. affine ciliare, with a period of eleven months from the maturity of the antheridia and archegonia and their contents in June, to the maturity of the sporophotes in the following May. This similarity of location, appearance and fruiting time between M. ajjine ciliare and M. Drummondii suggest the question of relationship between them, and if there is a relationship how close is it?

The question will lend an added interest to the observations of the coming season.

FURTHER NOTES ON CLADONIAS. VIE

Cladonia subcariosa, Cladonia mitrula and Cladonia leptophylla.

Bruce Fink.

Perhaps the first of our three species to be considered in this paper might better have been disposed of in the last paper of this series with Cladonia cariosa, to which species it it closely related. It certainly would seem that Cladonia mitrula , a very characteristic and common American species, should have first place in the considerations of the present paper ; and this species must be regarded as the central and important feature, the other two species as yet being very rare North American forms. However, in spite of its relative unimportance to the student of our Cladonias, Cladonia sub- cariosa, because of its closer relation to the species considered in the last paper, is entitled to first place in the caption, and in the considerations to follow.

Cladonia subcariosa (Nyl) Wainio Mon. Clad. Univ. 2:38. 1904. Prim- ary thallus persistent or rarely disappearing, composed of subdichotomously divided, irregularly laciniate or crenate sinuate, flat, ascending or suberect, aggregated squamules, which are large or medium sized, 3-17 mm. long and nearly as wide, sea-green above or varying toward ashy or olivaceous, below whitish or finally dirty-brownish especially toward the base, the cortex con- tinuous and no soredia present. Podetia arising from the margin, or rarely from :4the upper surface of the squamules, about 5-15 mm. long (rarely 30 mm.) and. 5-4 mm. in diameter, subcylindrical or thickened toward the top, cupless and always terminated by apothecia, simple or rarely furcate and often very shortly digitate, sides entire, finally fissured or rarely conspicu- ously rimose, the axils likewise usually closed or at length fissured, clustered or scattered, suberector rarely ascending, cortex subcontinuous orareolate, the areoles when present subcontinuous or quite close and scarcely elevated or elevated wart-like, without squamules or soredia or rarely sparsely squam- ulose, dull sea-green varying toward olivaceous or greenish, or the decorti- cate portions pale or whitish. Apothecia usually medium sized, .5-4 mm- in diameter, clustered-conglomerate, often somewhat lobed at the apex of the podetia or on their short branches, soon becoming convex and immarginate, brown or perhaps rarely varying toward reddish. Hypothecium pale. Hymenium brownish above and pale or brownish below. Paraphyses simple or rarely branched toward the thickened and brownish apex. Asci clavate or cylindrico-clavate.

This species may best be known from Cladonia cariosa by the larger squam - ules and by their shorter, unbranched or slightly branched podetia, which show a less marked carious appearance and less commonly and conspicuously

fissured sides and axils. The present species also bears a strong resemblance to the next below, from which it may be distinguished by the larger squamules and by the stouter, more nearly continuously corticate and sometimes more loosely apically branched, lighter colored podetia. Reference was made in the last paper to specimens called Cladonia symphycarpia Fr. , by American workers, and referred to Cladonia cariosa by Dr. Wainio, to whom the mate- rial was submitted by the present writer. However, some of these speci- mens with large or very large and much cut squamules, Dr. Wainio referred to Cladonia subcariosa, and this, in one or two instances, with few podetia, thus depending mainly upon the squamules, which in these specimens, at least, are very markedly different from those of Cladonia cariosa. By way of illustration of the squamules of the present species we give a few of these squamules from the plant noted below and collected in the Lookout Moun- tains byW. W. Calkins (his No. 85 of “ North American Lichens”) and dis- tributed by him as Cladonia sy77iphycarpia Fr. For the podetia we give illustration from a few separated from cespitose clusters as exhibited in a specimen in the writer’s herbarium, collected in Germany by Dr. F. Arnold, in 1897, which illustrates the podetia much better than any American mate- rial at hand (Plate IV. fig. 1, b).

On earth, especially on sand in open places. Determined by Dr. Wainio- from the writer’s herbarium as follows: Tacoma Park, D. C. (collected

Mabel E. Williams), and distributed in “ Lichenes Boreali-Americani ” (No. 178) as Cladonia sy77iphycarpia, and Lookout Mountains, collected by W. W. Calkins, who distributed it in his “ North American Lichens (Nos. 85 and 94) as Cladonia sy7nphycarpia. As for further North American distribution. Dr. Wainio adds Massachusetts, Texas and some adjacent islands. Known in all grand divisions.

Cladonia mitrula Tuck, in Dari. FI. Cestr. 444. 1853. Primary thallus commonly persistent, composed of subdichotomous, irregularly or subdigi- tately laciniate or crenate, flatish, ascending or suberect, clustered, small or middling sized squamules, which are 1.5-4 mm. in length and nearly or quite as wide, ashy to sea-green above and whitish below. Podetia arising from the margin or from the surface of the squamules, 3-12 mm. long and .4-1.6 mm. in diameter, cylindrical and cupless, always terminated by apothecia, simple or branched toward the apex, the branches erect or spreading, sometimes fissured longitudinally, the axils sometimes open, clustered or subsolitary, erect, contex continuous or composed of contiguous; or sub- contiguous areoles, or rarely partly decorticate and somewhat sorediate, sometimes sparingly squamulose, ashy to sea-green or the decorticate por- tions whitish. Apothecia small or middling sized, 1-2 mm. in diameter, soli- tary or clustered, sometimes perforate, at first flat and marginatebut usually becoming convex and immarginate, brown varying toward paler or reddish- brown. Hypothecium pale or brownish. Hymenium pale or brownish be- low, and brownish above. Paraphyses usually simple, commonly thickened and brownish toward the apex. Asi clavate (Plate IV. Fig. 2, a. b.).

On naked earth, frequently sandy soil, or rarely on old tree trunks in

— 59 -

more shaded places. Distributed throughout the United States, especially southward, being replaced largely northward by Cladonia cariosa (see la,st paper), but reported as far north as Alaska (“ Lichens of Alaska,” by Clara E. Cummings). Examined by the writer from Massachusetts (Clara E. Cum- mings and Henry Willey). Maryland (T. A. Williams,) North Carolina (C. / Russell), South Carolina (H. A. Greene), Lookout Mountains in Tennessee (W. W. Calkins, who distributed it as Cladonia cariosa ), Florida (W. W. Calkins), Louisiana (A. B. Langlois), Ohio (E. E. Bogue), Illinois (G. P. Clinton, W. W. Calkins and Bruce Fink), Iowa and Minnesota (Bruce Fink), Missouri (C. Russell and B. F. Bush), Nebraska (T. A. Williams), and British America (J. Macoun). Dr. Wainio’s Monograph would add Texas, New Jer- sey, New England, Pennsylvania and Mexico. Known also in South America.

Dr. Wainio calls the typical form on earth Cladoiiia mitrula imbricata (Nyl) Wainio, and says the form on trees in somewhat open places is Cladonia mitrula abbreviata Wainio Mon. Clad. Univ. 2:i6. 1894. The last he cites from Brazil, and distinguishes it by smaller podetia, which are only .5-5 mm. long and .3-. 5 mm. in diameter. We may well look for this diminutive form .in our territory.

H. A. Green’s specimen from South Carolina, referred to Cladonia cariosa , is perhaps nearer the present species.

Cladonia leptophylla (Ach.) Flk. Clad. Comm. 19. 1828. Primary thallus commonly persistent, composed of subrotund, entire, crenate or rarely incised, flat or more or less convex, appressed or ascending, clustered squamules, which are. 5-2 mm. in length and width, whitish or pale sea- green above and pale below. Podetia arising from the surface of the primary thallus, 2-9 mm. long and 1-2 mm. in diameter, subcylindrical, cupless, always terminated by apothecia, simple or rarely fastigiately branched and the branches suberect, the sides commonly more or less open, the axils some- times fissured, clustered or scattered, erect, commonly decorticate and more « or less finely sorediate, rarely more or less squamulose, whitish or pale sea- green. Apothecia small or middling sized, 1-3 mm. in diameter, subsolitary at the apices of the podetia or on the branches, commonly convex and immar- ginate, brown or pale reddish brown. Hypothecium pale or pale-brownish. Plymenium pale or pale-brownish below and brownish above. Raraphyses commonly simple and frequently thickened and brownish toward the apex. Asci clavate or cylindrico-clavate.

This species is by no means easily distinguished from the last from any description. But the squamules are only about half as large, are not so ir- regular in form and are never suberect, being flat or ascending. The podetia are on the whole shorter and thicker, and more inclined to ecorticate and sorediate conditions. The first material sent to Europe by the present writer was sent to L. Scriba, who sent part of it to Dr. Wainio. It was sent as Cladonia mitrula, to which Scriba agreed, Wainio calling it Cladonia lepto- phylla. The writer afterward submitted again to Dr. Wainio material from a packet, which Mr. Scriba had returned to him with some European cladonias, the packet being part of the material originally sent to Scriba, collected all in

— 6o —

one cluster on a clay bank. Dr. Wainio this time called the material Cla- donia mitrula. This statement is submitted primarily to show that the species is difficult to distinguish and that the Iowa material is not certain, and in no sense to cast reproach on the work of any other lichenist. It is only those of very limited experience in taxonomic work, or who have very poor powers of observation, who suppose that a really good worker may not sometimes make different diagnosis of material that is intermediate between two species, the difference being due rarely to incomplete consideration of every diagnostic character, and no doubt more often to the fact that material from the same Cladonia cluster may often .show a considerable amount of variation.

Material from Battle Lake and Leaf Hills, in Minnesota, collected by the present writer, is like the Iowa material, which is in turn doubtful. Henry Willey reported the species in his “ New Bedford Lichens,” but Dr. Wainio seems not to have known of this material. Dr. Wainio cites a single Ameri- can specimen in his Monograph. This is cited doubtfully from Carolina. Thus there is room for doubt as to whether this species has really been found in America. The plant occurs on soil, especially clay, and is known in Europe and Asia. Grinnell, Iowa.

MOUNTING MOSSES— SOME HINTS.

J. Franklin Collins.

In the September, 1903, issue of this journal Mr. Chamberlain described the method which was employed a few years ago to fasten moss envelopes to herbarium sheets in the Brown University Herbarium. It may be of interest to readers of The Bryolo.gist to learn of the method which has superseded it. The latter method has been used more than two years in the University Herbarium, as well as in*my own private one. Gummed wafers are utilized instead of pins. The particular wafers which we use are made of a half-inch circle of white paper, well gummed on both sides. They may be obtained for a few cents a thousand from almost any stationer. To use them to the best advantage a single wafer is graped by the edge, with slender pointed forceps, and moistened on both sides. It is then thrust between the envelope and mounting paper, the former having been placed in the proper position on the latter before the wafer is moistened. A firm finger-pressure for one or two seconds over the wafer is sufficient to cause it to adhere securely. The forceps points are withdrawn as soon as the pressure with the finger is ap- plied. Unless the envelope is a large one a single wafer is generally suffi- cient.

In case the envelope has to be transferred to another sheet it is instantly removed by one sweep of a paper knife, or other blunt-edged instrument, be- neath the envelope. The wafer usually splits, leaving part on the sheet and part on the envelope. This slight disfigurement of the sheet, which is often soon covered by another envelope, may be regarded by some as an objection to the use of the wafers. This disfigurement only occurs, however, when

— 6i —

an envelope has been removed, and even then is not much greater than that caused by several pin holes and the accompanying wrinkles in the paper. To the writer the only real argument against the use of the wafer lies in the fact that when an attached envelope is grasped by the edges and lifted away from the paper (a condition which never ought to occur, perhaps, in a care- fully handled herbarium) the watered envelope is — as is shown by tests — much more easily detached than the pinned one : the ratio of energy required to detach it being 16. To offset this, when an attempt is made to detach an envelope by pulling it along the surface of -the sheet without lifting it, the watered one necessitates more than twice the energy required by the pinned one (7:3). The advantage is also most decidedly with the watered envelope (10-15:1) when a twisting strain is applied.

Some of the obvious advantages in using wafers— when compared with pins — are as follows: The envelope does not have to be opened when it is

being fastened to the sheet, nor during its removal ; the watered envelope is more quickly and easily fastened, and its removal is even more quickly accomplished : the wafers cost considerably less than the pins : neither paper nor envelope is perforated : the back of the sheet is smooth, with no pin shanks to rub specimens beneath. Although the pin shanks rarely harm specimens beneath, the danger of their doing so exists nevertheless.

In a moss herbarium which is to be constantly consulted there are obvi- ous advantages in having a portion of each specimen mounted on the herbar- ium sheet, outside the envelope. Much time, which would otherwise be utilized in opening and closing envelopes, is thus saved. This is really quite an item when one’s time is all' too limited, and a hand-lens examination of several or many specimens becomes necessary or desirable. The writer’s method of mounting such specimens is not essentially different from that in common use for mounting seed-plants in most of the large herbaria. Liquid glue is brushed in a thin layer over a plate of glass. For mosses this glass need not necessarily be larger than 6 x 8 or 8 x 10 inches. Into this film of glue the specimen is pressed until the glue touches the essential portions of the under surface of the specimen. The latter is now lifted with forceps and laid on the mounting sheet in the position desired, and finally a suitable light pressure applied until the glue sets. A few words of caution to those who have never used this method for mounting mosses may be helpful. The commercial liquid glue should be diluted more or less, as experience dictates, with either water or vinegar — about -equal parts of glue and vinegar is the proportion commonly used by the writer. It must be borne in mind that water and vinegar moisten the moss and often cause more or less of a change from the typical dry state in such parts as come in contact with either fluid. Con- sequently, care should be taken to allow only the lower surface of the speci- men to touch the glue-covered plate. It is almost equally important not to allow the specimen to remain in contact with the glue longer than required to touch the desired parts, as otherwise there is danger that the glue will creep or filter through to the upper surface of the specimen — not only moisten- ing that surface but often leaving unsightly films or spots. This is a simple

— 62 —

and efficient method of mounting most mosses, especially such as have been somewhat flattened while drying under slight pressure. At certain other times it may be more advantageous to apply the glue directly to the back of the specimen.

Many bryologists have been exceedingly annoyed by the disfiguring par- ticles of sand or soil which rattle or rub out from the matted stems and rhizoids of certain mosses, when mounted on paper. This annoyance is espe- cially pronounced in plants which grew on sandy or clayey soil, or in such plants as Bruchia, and others of similar habitat, where it is desirable to retain, with the plant in the herbarium, a block. of clayey substatum. For- tunately, there is a simple method of mitigating this evil and, in most cases, of entirely overcoming it. After the specimen is mounted in the ordinary way apply a few drops of diluted white shellac to the parts which are expected to prove troublesome in this respect. Care should be taken to apply the shellac to only one side of the substratum (not to the specimen) or an unsightly shiny spot may be evident when the solution dries. The writer has on his work table a small (i oz.) reagent bottle with a rubber-topped dropping tube. This bottle is about half full of a mixture of shellac (i part) and 95 percent, alcohol (about 3 parts) which is used for the purpose mentioned. If, after drying, a thin film of shellac is obvious on the substratum or specimen, it is probably due to the fact that the shellac was not sufficiently diluted, Or else too much of it was used. The moral is obvious. In most cases dissections wiil be made from specimens left in the envelope. Sometimes, however, it may become necessary to dissect specimens which have been treated with shellac. The preliminary application of a few drops of alcohol, or even a rins- ing in that fluid, is then advisable. Providence, Rhode Island.

“ Chemical Tests ” in Determining Lichens.

G. K. Merrill.

In 1866 the late Dr. William Nylander published the results of his experi- ments regarding the behavior of certain aqueous chemical solutions, when applied to the cortical and medullary layer of the lichen thallus. The chemi- cal menstrua found most effective and useful were potassium-hydrate and calcium hypochlorite, symbolized as KHO and CaCl. The results obtained hinged on a capacity of the solutions employed to produce a coloration on ap- plication to that portion of the thallus to be tested. Dr. Nylander claimed to have found that different lichen species were differently affected by the re- agent employed, but that individuals of one species were constant in the pro- duction of a given reaction. The object of the test was to assist “in not only the discrimination of many difficult and closely allied species, but also in associating varieties with their proper species, and in some instances in de- fining the affinities of genera.”

The novelty of constituting botanical varieties on purely chemical grounds aroused antagonism at the time, which has persisted more or less to the pres- ent day, but the unquestionable value of the discovery as an aid in the de- termination of established species, made converts of nearly the whole body of European lichenists. Among those to negative the value of “chemical tests ” from the first, was the late Prof. Edward Tuckerman, and it is regret- fully stated that his views were adopted with great uniformity by the later American investigators. It will be of interest to quote from the published words of those Americans who have written on this topic.

In the American Naturalist for April, 1868, Tuckerman first voiced the disapproval, and we will selectively quote from his paper. Under the cap- tion, “ Can Lichens be Identified by Chemical Tests?” he says: “ I have

gone through a large part of my North American and exotic lichens in the light afforded by these (Nylander’s) experiments and found the facts, if sometimes suggestive of more than is stated, generally clear: much clearer than the value attributed to them. Is it not indeed safe to say at once that species are not determined in botany by such tests Y” “ The observations cited are however incomplete ; and derive from this not a little of their inter-

-67—

est. Parmelia per lata Volxis said to differ from its var. olPdetorum Ach. by failing to show any red tinge with chloride of lime, the difference already recognized being regarded as sufficiently corroborated by the new one. But all specimens of P. d live tor um are not so distinguishable. It is much the same with P. Icevigata and its var. yevoluta Nyl. (Syn. p. 385), the last being now taken and on better evidence to be distinct in species from the first. We have here a better marked difference in botanical character, one which commended itself as sufficient to Floerke, and at one time to Borrer ; and there seems to be no doubt that the original P . revoluta Flk. is discrep- ant from common states of P . Icevigata in the chemical respect also.”

The learned author goes on to say that all his European specimens of P. tiliacea afford a distinct reaction, with which only two or three of the rela- tively abundant American forms are concurrent. He also finds that Arctic, Tropical and Texan forms of P. caparata give a plus reaction when they should be minus; that P. physodes Japonica Tuckerm. is plus when the physodes group is conceded to be minus ; and that while P. Borreri is recorded as plus, no reaction is observable with the specimens in his herbarium. The concluding lines of the paper are interesting, for Tuckerman affirms that, “these results given with due respect to the experienced authors whose ob- servations have been considered, sufficiently indicate that the writer inclines to emphasize the doubts with which Dr. Fries has received the supposed new criteria of distinction. It remains none the less likelyfrom whatevidence we have that the reagents named, capable as they are of instructive application to imperfect fragments, may sometimes afford clews to affinity where there is little to direct : and thus deserve a place besides the better known solu- tion of Iodine on our working tables.”

In the Genera Lichenum, 1872, Tuckerman in discussing the tendency of the Europeans toward species splitting, reiterates his disapproval of chemical tests. Referring to what he terms a “ laxity of conception ” regarding speci- fic delimitation, he says, “ This is seen at least in the very generally as- sumed value of recent experiments on the behavior of lichen-tissues with certain chemical tests : species having come at last to have no other meaning than a chemical one ; namely, that they exhibit (so far, it is important to say, as the examination has gone) a different reaction from forms with which, in every other respect, they are admitted to agree.”

In his Synopsis, Pt. 1, 1882, Tuckerman makes no general allusion to chemical tests, such remarks as are noted being limited to instances of per- version from the recorded results of the Europeans. It is easy to see that chemical tests are viewed with hostility, although his attitude is evidently a passive one. In an extract from the Botanical Gazette, April, 1896, Mr. Henry Willey, of New Bedford, Mass., briefly takes up the matter of chemical tests in relation to the genus Parmelia. The paper, which is en- titled. “ Notes on Some North American Species of Parmelia,” catalogues the reactions for a number of species, the reagents employed being potassium- hydrate and calcium hypochlorite. Willey remarks, “Of the chemical rela- tions I am unable to attach absolute specific value to them. There are

-68-

exceptions to their constancy, some of which were pointed out by Tuckerman in a paper in the Am. Nat., April, 1868. It is possible that a lichen may possess different chemical constituents at different stages of growth, or under different conditions of soil, climate, etc. Experiment on the same plant at different periods of its development is necessary to confirm the deductions from simple examination. Still, the reactions appear to be constant in most of the species of Parmelia and may serve as an aid in their determination, while the exceptions remain to be accounted for. Where there appears to be an exception we may best say that perhaps the specimen belongs to a dis- tinct species.’’

Prof. Albert Schneider, in his Text Book of Lichenology, 1897, says of chemical reactions: “For some years the chemical behavior of lichens to

certain reagents has been considered of great importance in delimiting spe- cies. After careful testing I have finally decided to abandon the use of these reagents since they are practically valueless for the purpose recommended. That there are marked chemical reactions cannot be denied : for example, the blue Iodine reaction of the thecial wall of the majority of lichens. This reaction is, however, so general in its occurrence that it cannot possibly be of any value in establishing species, and the coloration varies in different indi- viduals of the same species, or even of the same plant at different periods of development. The same may be said of the other reactions as those with solutions of potassium-hydrate and calcium hypochlorite. That these reac- tions should be unreliable is evident when we consider the life history of lich- ens; different individuals of one and the same species may develop on substrata of widely different composition. These chemically different sub- stances adhere to the lichens, and some soluble constituents are also taken up by the fungal symbiont which accounts for the difference and unreliability of the chemical reactions.

Prof. Bruce Fink, in his Presidential address to the Iowa Academy of Sciences, pays his respects to the subject through an allusion to Dr. Nylander- He says: “ Nylander was doubtless too much given to species making, and

it is unfortunate that he depended too much on chemical tests in his determ- inations.” A few pages further on Fink, in alluding to Tuckerman’s ex- pressed opinion of theunreliable nature of cnemical tests adds, thatsuchis “a view which I suppose meets the approval of latef lichenists generally, since we have reached more definite knowledge regarding the anatomy of these plants.” In another paper presented before the same Institution entitled, “ Notes on American Cladonias,” Prof. Fink says, “ as to chemical tests it is extremely doubtful whether they are of diagnostic value in any lichen.” The writer will add to these excerpts of American opinion on chemical tests, the information communicated by Prof. W. G. Farlow, of Harvard University* that Tuckerman “never changed his opinion in later years with regard to use of chemical tests in distinguishing species of lichens. He did not consider that species could be distinguished in that way.”

To summarize the foregoing expressions of opinion is to assort belief into two groups. Schneider and Fink are associable in the first, for both repu-

— 69—

diate chemical tests altogether. Tuckerman and Willey comprise the second, each conceding the chemical test to be of more or less value in determining established species, but dissenting from the view that the establishment of specific botanical varieties on chemical grounds is possible without such are confirmed by morphological characteristics. The writer has no personal knowledge of the extent to which Fink and Schneider have carried their ex- periments with reagents. The latter indeed says that his investigations were pursued to a point where he was convinced of their futility, but Fink fails to specify. It might be assumed from the fact that neither gentleman is at all reserved in his statements, that they have delved deeper than did Tuckerman or Willey. It would be an interesting contribution to American lichenologi- cal literature if one or both should set forth ab initio the successive dis- coveries leading to their conclusions as published.

With the guardedness which was characteristic of the man, Tuckerman, in the 1868 paper, after having boldly condemned chemical tests, is finally found to qualify his conclusions. In the concluding lines he admits that the “instructive application of reagents to imperfect fragments might some- times afford clews to affinity.” If chemical tests may be relied on in determ- ining fragments, it is suggestive that if the investigator were working on a satisfactory specimen the results might be proportionally superior.

Dr. Th. M. Fries, whom Tuckerman quotes as offering opposition to the new tests, according to Leighton soon came to believe in their value, and his personal experiences are found incorporated in “ Lichenes Spitzbergenses,” and “ Lichenographia Scandinavica.” After Tuckerman’s death Willey en- tered into closer relations with the European lichenists. One result of his correspondence with Nylander may be gathered by a persusal of the notes on Parmelia, 1. c. In this paper Willey states that “ there appear to be known about forty species ” of Parmelia in North America, as contrasted with nine- teen mentioned in Tuckerman’s Synopsis. He acknowledges that many of the new names were the result of Nylander’s examination of New Bedford and other material, and that the separation hinged on “chemical or other grounds.” The paper contains some admissions that might easily be taken as evidence that Willey had shaken off the mantle of conservatism and joined the enemy, if it were not for his explicit statement of inability to “attach absolute specific value ” to the chemical relations. All who have had any personal acquaintance with Willey will agree that if he ever attached to the specimens of his herbarium a name prompted by Nylander it was done with full knowledge of the masters’ position on the chemical phase of species making ; and such a course must be regarded as a tacit avowal of belief. A curious point may be made from Willey’s paper to illustrate the notorious diversity of results obtained with reagents in the hands of different experi- menters. Tuckerman referred to his results with various species of Parmelia to show their discrepancy from published findings; and Willey remarks that the “ reactions appear to be constant in most of the species of Parmelia,” and then adds that the fact “ may serve as an aid to their determination.” Here is a clear discordance of opinion with no explanation ready at hand. It is

—70—

difficult to believe that the lack of conformity is due to a difference in inter- pretation of fact, nor is it thought to be an effect of similar specific lichen forms furnishing dissimilar phenomena. A possible explanation may be that Willey, under the guidance of Nylander, came to have a better knowl- edge of Parmelia species than did Tuckerman, and a more exact conception of the things to be recognized in chemical testing.

The student on first taking up the subject of chemical criteria is apt to find it difficult to exactly determine what constitutes a satisfactory test. The manuals contain fairly clear directions, but mere words only convey an out- line, leaving experience to supply the details. There are some tempera- mentally unfitted to make use of the tests, and others, solitary workers, without guidance except for the books. Both fail from obvious reasons. In their inception chemical tests were only recommended as aids to the char- acterization of lichens, and much of the early antagonism to their employ- ment is attributed to a misapprehension of their point. In the Annals and Magazine of Natural History, 1869, Rev. W. A. Leighton (Not. Lich. XVIII) in reviewing Dr. Th M. Fries’ Lichenes Spitzbergenses, takes occasion to say, “With much satisfaction we observe that the learned author has over- come his prejudice against the application of chemical tests in lichens, and has made ample use of them with very satisfactory results. He, however, still appears to labor under a misapprehension that the advocates of chemi- cal tests wish to inculcate that species may be distinguished by chemical means alone (hac sola nota). All that has ever been ascribed to them is that they are most useful and indispensable aids as affording confirmatory char- acters and in discriminating doubtful or externally allied species. In the Cladoniae he has almost uniformly confirmed the results of our own exam- ination of the tribe. But it may be well here to correct a doubt which seems to exist in consequence of the chemical test producing in certain species a slight degree of fuscescence only, by explaining that when the proper reac- tion takes place it does so instantly, and that the fuscescence which is in some instances observable is not to be regarded as a reaction at all.”

In the same publication for 1869, Leighton (Not. Lich. XXIX) again writes, “ The student is especially warned against misconception as to chemical tests constituting a sole specific character. All that has ever been asserted re- specting them is that they afford an additional and confirmatory specific character. And in those cases where external characters are similar or ap- proximate, and doubt necessarily exists, their value as such will be abun- dantly apparent.” Leighton then proceeds to quote Jfrom a paper by Dr. Nylander, aptly designating the citation as an “ admirable caution.” The learned Doctor says: “The analysis of lichens made by chemists often fail

through the neglect of an exact determination of the species, and probably not less often by the mixture of specimens confounded together and incor- rectly assigned to one single species. For the chemist no less than for the physiologist it is of the greatest importance to know exactly what is the plant we have under observation — that is, to have well determined the plant which we are studying.” In other words, returning to Leighton, “he must not

-71-

place implicit confidence on the attached labels as indicating undoubted accuracy, or on his own preconceived notion of the particular diagnosis, but by careful observation and comparison thoroughly satisfy himself that the plant under review is really that which the label indicates it to be. Then apply the chemical test and doubt will be exchanged for certainty.”

Leighton is far from clear in the last sentence — perhaps his meaning is that in the hands of the other experimenters, comparison of their own results with records of accurate work might produce a feeling of certainty. A de- termination that is established beyond question on other grounds, needs no chemical bolstering. In the light of the foregoing the whole question of the usefulness of chemical tests to lichen students resolves itself on the real or presumed ability and* knowledge of whomsoever may have made the primary series of tests. No one will gainsay Dr. Ny- lander’s standing as a lichenist, or question his knowledge of lichen species, whatever the aspect. Is it not reasonable to say as Nylander was learned beyond all men in lichenology, aud well enough acquainted with species to be enabled at all times to dispense with chemical tests,, that whatever conclusions he reached in his searching investigations into reagents and their application, should be regarded as convincing? If Nylander, or. for that matter, any accomplished lichenist, should examine an extended series of specimens of a morphologically proven species, these from widely separate localities and various substrata, and on application of rea- gents find that all gave the same coloration, how might the sceptic best re- fute such results ? Would the statement of the doubting one, that in his hands no such uniformity was obtained, have any controversial value ? We think not, except to himself. Tuckerman was primarily responsible for the determination of most of our American lichen species, and up to the time of his death very few looked beyond his opinion. It then seems like a violation of things sanctified to express the belief that no small part of the failure of our students to obtain concurrent reactions in tests, has been due to application of reagents to plants of species other than what the investigator supposed he was examining.

The writer will add a few notes on matters of practice in using the rea- gents. Instead of employing a glass brush as recommended by Leighton, a medicine dropper is used. In cases where no distinct coloration of thallus or medulla is observable on application of the solution, if it is withdrawn from the surface of the specimen within the tube it will sometimes be found tinged and may then be taken for a very delicate test. It is advisable in testing with calcium hypochlorite, after application, to examine the thallus where abraded, with a hand-lens. The coloration is sometimes very faint, and only thus to be distinguished. In conclusion, it may be said that in our hands chemical tests have proven all that the French lichenists assert, but we desire it to be understood that in no way are we in sympathy with “chemical species.” Rockland, Maine.

TWO ANOMALIES AND A CURIOUS SIGHT.

B. D. Gilbert.

In Dixon’s Handbook of British Mosses, under the description of Leuco- bryum glaucum, it is said that “ A curious state from Hedsor forms spher- oidal balls or cushions, entirely unattached, consisting from stems radiating outwards from a central point, and showing no lack of vigorous growth in spite of the freedom from anything like attachment, which obviously must have lasted for a considerable period.” During the summer of 1905 I was on the west branch of the Unadilla River, in the northwestern part of Otsego Co., New York, hunting for mosses. In the hemlock woods a great deal of Leucobryum glaucum grew upon the ground. I stooped to pick up a tuft of it, and it proved such a “cushion ” as is described in above quotation. It is about inches deep and 2>lA inches across. It is almost perfectly round on the edges, and both above and below the growing ends of the stems are shown. They truly “radiate outward from a central point.” The fact, how- ever, which Mr. Dixon did not know, not having seen the plant in silu, is that the cushion grew in a matrix of its own diameter and about half an inch deep. But it was entirely unattached to the soil or any substratum, and must have derived its material for growth from the atmosphere and the rain which fell upon it. This is my fir(st anomaly.

In August of the same year I visited Caroga and Canada Lakes in Ful- ton Co., N. Y. The western end of Caroga Lake is very deep, and the shore is lined with large rocks that extend down into the water so that one can row directly alongside them, and occasionally land upon them. Many mosses grow on these rocks, and one of the rocks in particular, a very large one with a steeply inclined surface, was chiefly covered with Sphagnum acutifolium , probably the variety quinquefarinum , a short form but well fruited. Dixon says of this moss that it grows “ very fine and well marked on wet rocks in mountain woods.” The surface of the rock was kept constantly moistened by water that trickled down over it from damp ground above. The anomaly here was that the Sphagnum grew freely on a rock which contained no cov- ering of soil. Of course the trickling water explains the apparent anomaly.

The mountains around Canada Lake are much higher than at Caroga, and there several cliffs at the summit. On West Canada, one of the landing places goes by the name of “ Big Rock” camp. It is so called from a big rock lying up the hill about forty rods from the water. It is as large as a good-sized house, and probably thirty feet high. The face, which fronts down hill, is nearly vertical, and this front is well covered, from five feet above the ground upward, with separate fronds of the lichen Umbilicaria Dillenii Tuckerm. Each drab colored button is centrall)?- attached to the rock from which it is easily detached entire. The edges of the fronds do not touch each other, and the sight of this large surface so completely studded with them is one not often encountered save by the lichenist in search of specimens. The rock appears to be of Plutonic or Archaean origin, and consequently unstratified. I am not familiar enough with lichens to know whether the species is confined to this class of rocks or not, but it grows there with great luxurience, and is a sight well worth seeing. Clayville, N. Y.

THIRD BOTANICAL SYMPOSIUM.

Joseph Crawford.

The very successful Summer Botanical Symposium, recently' held at Little Moose Lake, in the Adirondacks, was a graceful compliment to Mrs. Hugh M. Smith, who not only secured permission for us to use the forest pre- serve of the Adirondack League Club, but planned expeditions to various points for our special work and maintained the agreeable role of hostess throughout the week, very ably assisted by Miss Masters, another League member.

The headquarters were established in Mountain Lodge, delightfully situ- ated on the north shore of Little Moose Lake, with easy trails in all direc- tions, by land and water, though one or two guides were necessary many times for obvious reasons, with an extra supply to act as ferrymen when the start was made across the lake.

Being a preserve, the forest is intact as far as we could penetrate, and while we reached no great altitude, the highest, Panther Mountain, being only 2460 ft., the northern mountain flora was everywhere evident. The hardwoods were of the maples, beeches and birches; the cone-bearing, the spruces, balsam, arbor- vitse, hemlock and larch; the undershrubs of hobble- bush and huckleberry serving as a cover to the ever-present mountain sorrel and lycopods.

Most of the lakes are deep and protect little vegetable growth, though some small ones with quaking- bog borders were quite prolific in orchids, sun- dews, heaths and sedges. Ferns were very evident everywhere and ranged from the small moonwort to the enormous fronds of bracken nearly six feet across. The most common fern was the variety intermedia of Dryopteris spinulosa. The northern orchids were also abundant, many species just approaching the flowering stage. The mosses, hepatics and lichens were remarkably abundant and in excellent condition but we could not add a whit to Mrs. Smith's very complete catalogue of them. Owing to the forest form- ation the grasses had very slim chances, likewise the sedges except in bogs and other moist places.

It is yet too soon to go into detail of the work done during the week ; but the energy displayed then and there will have a great showing from, and including, the porcupine feast and funeral, to the continuous mosquito smudge and punkie dope. There is an unwritten law distributed among us that each year we must prove in the field, existence of new species, this year notwith- standing the presence of several well known makers of genera and species there were times when they were out of sight, and the evidence of the amateur became pronounced.

The July Bryologist was issued July 2, 1906.

—74—

The evening sessions were held in the large room over the boat house and were manifestly interesting, topics of the day’s observation and collec- tions so freely discussed that the scientific part of the Symposium lost noth- ing on account of the sociability which it fostered ; in fact both features have now become so pronounced that there is little doubt that the next meeting will be more than a week’s duration.

The whole atmosphere of Mountain Lodge has the greatest homelike moral medium about it, that to breathe it is simply delightful and reflects great credit upon Mr. A. G. Shepard, Jr., the trustee in charge, and on Mr. and Mrs. Studor, the managers, and we trust they may always be so success- ful in maintaining it. Philadelphia, Pa.

BOOK REVIEW.

A Revised Key to Hepatics of the British Islands. By Symers M. Mac- vicar, 20 pp. 8vo. Eastbourne, 1905. Published by V. T. Sumfield, Station street, Eastbourn, England, @gd.

A review of the Census Catalogue of British Hepatics appeared in the March, 1906, number of The Bryologist and recently we have received another work by the same author, entitled as abo.ve. The Preface contains some useful hints in practical working for the beginner. We have had no chance to tests the keys but they appear to be carefully worked out. As stated they are intended to give beginners an indication to the species so as to enable them to identify their .specimens from the description in a text book. A. M. S.

SOME CHARACTERISTICS OF LOPHOZIA 1NFLATA AND CEPHALOZIA FLUITANS.

Caroline Coventry Haynes.

The above mentioned species with Lophozia injiata (Huds.) M. A. Howe var. heterostipa Lindb. share the following traits : in being aquatic, though the Lophozias are also terrestrial in habit ; in showing the same prostrate manner of growth : in possessing bifid leaves with obtuse lobes ; in being dioicous. On closer examination, however, this Cephalozia fluitans (Nees.) Spruce, will be found to possess characteristics peculiar to this genus, such as the position of the perianth on a short lateral branch, the numerous stout flagella arising from the axils of the underleaves in a truly postical manner: the linear-fusiform thin perianth with tristichous .involucral bracts toothed at the base, the innermost embracing the perianth.

On the other hand, the delicate flagella of the Lophozias arise variously from the mid-axil of a leaf or from its postical angle: the perianths occur at the apex of a stem or of a long leafy branch; the involucral bracts are dis- tichous and are similar to the stem leaves, often smaller and are remote from

—75—

the perianth, which is so completely exserted as to appear almost stipitate; the perianth itself is pyriform, inflated and obscurely 4-5 plicate only at the very apex, with a mouth connivent, denticulate. This genus shows two methods of reproduction, first, by the branching of shoots and the dying of the stem in between, and second, producing gemmae on the tips of the leaves. The first method is very limited in L. infiata , stems with fertile perianths and those with androecia, also those' sterile are generally unbranched ; while one or two subfloral innovations are to be found on stems with unfertilized perianths ; no gemmae are found on this species or its variety and it was difficult to understand its wide-spread (distribution.

Right here I would like to refer to a very interesting paper on Lophozia infiata by. fieri* Schiffner, published in Ascherson’s Festschrift* A trans- lation of this was very kindly furnished me by Miss J. T. Emerson. Dr. Evans, in calling my attention to this* paper summarized it as follows: “the deciduous perianths in L. infiata really represent organs of vegetative repro- duction, new shobts arising from their cells', and he finds that they serve the same purpose in var. heterostipa but not in C. fluitans .” Schiffner says that these easily detached perianths are produced ip great profusion and develop normally to the point where the fertilization of the enclosed archegonia takes place; at this stage it is impossible to foretell whether they will become fertile or so called sterile perianths. The slightest touch sufficing to break off these latter, their buojmncy keeps them afloat and they are carried off, some to the shore to which they attach themselves and start growing, sending out rhizoides and shoots which when mature are the typical infiata.

The illustrations were , made from fresh material furnished me by the following : Miss Lucy MacIntyre, the A. infiata , collected in a bog at Long

Branch, New Jersey. The abundant perianths were very deciduous, the plants were growing with Rdllavicinia Lyellii (Hook.) S. F. Gray; the var. heterostipa was collected by Mr. A. S. Foster at Hamilton, Wash., and was growing with Mylia anomala (Hook.) S. F. Gray, this latter species being new to this state; Miss An nib Lorenz and Mr. E. B. Chamberlain, collected the C. fluitans in New Hampshire and Maine, respectively. All these specimens form part of our Chapter Herbarium and it is hoped that students will be on the lookout for these tiny and interesting species and contribute duplicates of their finds. /

The leaf subtending a lateral branch in L. sylvatica is sometimes bifid and sometimes undivided; in other cases there is no subtending leaf what- ever. The latter condition in fact is normally found on one side of a branch- ing axis while subtending leaves occur on the other. The absence of such a leaf indicates that the whole, instead of a part, of an apical segment has entered into the formation of the branch. This substitution of a branch for an entire leaf is of special interest and has not before been noted in the Hepaticae, although its occurrence was long ago suspected by Leitgeb. The subtending leaves are sometimes found on the left, according to the direc- tion of the spiral. Similar variations also occur in L. setacea

In their vegetative organs L. setacea and L. sylvatica resemble each other very closely, and it is sometimes difficult to determine sterile and poorly developed material. Usually, however, the leaves and especially the underleaves offer a few reliable points of difference. Under favorable con- ditions L. setacea is more robust, and its leaves are more regularly quad- rifid ; in many cases the antical segment bears an accessory tooth on its free margin, a condition which is exceedingly rare in L sylvatica. Occasionally a bifid subtending leaf will show an accessory tooth of this character on each side. The cutitle of L. setacea is distinctly verruculose while that of L. sylvatica is smooth or very indistinctly roughened. Unfortunately in slen- der forms of L. setacea these differences are not always apparent.

PTYCH0MITR1UM LEIBERQII n. sp

G. N. Best.

In loose tufts, olive green above, ferruginous below: stems i cm. long, erect, central strand small, distinct: leaves thickish, crispate-incurved when dry, erect-spreading when moist, somewhat undulate, entire, margins plane, 3.5 to 5 mm. long, .6 to .8 mm. wide: from a concave, suboval base gradually linear-lanceolate, acute or blunt pointed: nerve thick, reddish, disappearing at apex ; lamina mostly unistratose, bistratose in streaks above and on the margins; leaf cells uniform, somewhat distinct, median chlorophyllose, roundish-quadrate, 10/z, basal broadly rectangular, pellucid: monoicous: antheridial buds at base of pedicels, stipitate; perichetial leaves similar to but larger than stem leaves: pedicels reddish, 5 mm. long ; capsules erect, elliptical, 1.3 mm. long. .7 mm. wide, wrinkled when dry; annulus broad, 3 rowed, separating readily and in fragments: exothecal cells thin-walled, polymorphous, 3 to 5 rows about the mouth thick-walled, reddish, flattened; peristome simple, teeth narrowly linear-lanceolate from a broader articu- late base, yellowish, coarsely papillose, more or less irregularly divided, sometimes nearly entire; operculum acicular, .1 mm. long, zigzag on margin; calyptra campanulate, deeply lobed, plicate, rough at apex: spores minutely roughened, 13 to 16 ju: matures in the early part of February: on rocks, collected by John F. Lieberg, in whose honor it is named, near the south end of Baboquivara range, Arizona, February, 1906 : altitude 4000 ft.

Cotype in the Herbarium of the New York Botanical Garden.

Ptychomitriicm Leibergii differs from P. Gardneri by its smaller size, entire leaves, somewhat undulate but not plicate, and by its peristomial teeth not divided to the base into filiform segments. The leaves in P. incurvum are bistratose above the middle, leaf cells smaller and less distinct and the peristomial teeth entire.*

In P. Druimnondii the leaves are denticulate-serrate, the peristomial teeth shorter and broader and split at apex and the annulus wanting. The leaves in the Mexican P. rugosum (Mitt.) Jaeg. are serrate above and re- flexed below.

It would therefore seem that so far as the North American species of Ptychomitrium go P. Leibergii is well marked and quite distinct. Unfortu- nately it is described from a single collection. Future collections may show variations not recognized in this description. Mr, Leiberg assures me that it is “common in the mountains of southern New Mexico and Arizona from the Floridas in the former territory to the Baboquivara range in the latter, and probably extending much farther westward : southward into Mexico . not observed north of Southern Pacific R. R.” I am indebted to Mrs. Brit- ton for an examination of this moss and for the opinion that it is an unde- scribed species. Rosemont, New Jersey.

*Mrs. Britton claims that P.pygmceum is only P. incurvum (Bull. Tor. Bot. Club, 21:497}. However this may be I am of the opinion that we have two species passing as P. incurvum differing in size, basal cells and peristomial teeth, possibly connected by intergrading forms.

SOME ADDITIONS TO THE^FLORA OF MIDDLESEX COUNTY, MASSACHUSETTS.

Reginald Heber Howe, Junior.

The following plants were not included among the Lichens attributed to this County by Messrs. L. L. Dame and F. L. Collins in their List, pub- lished in 1888 The preface to the “Lichens” in the above work, will show that these additions are only a few, compared with those that may still be added, and are in no way remarkable. For the records from Sudbury, I am indebted to Miss C. M. Carr.

1. Ramalina calicaris fraxinea Fr.

This subspecies is not uncommon in Concord and Carlisle, on ash and elm trees. In only a few instances are the plants absolutely typical, the majority being somevhat intermediate between fraxinea and fastigiata.

2. Cetraria Oakesiana Tuckerm.

Not uncommon in' Concord, on base of conifers and birch. Reported from Sudbury.

3 Usnea barbata florida rubiginea Michx.

Not uncommon in Concord, growing in a reduced state on black spruces, white pines, and particularly on rocks. Always sterile.

Usnea barbata ceratina Schser.

I have one example referable here.

5. Usnea barbata florida s trig os a Ach.

Uncommon. Collected in Concord and Bedford on Maples. Fertile.

I have collected one example of this species in Concord, on an old stump and it is reported as not uncommon in Sudbury.

11. Stereocaulon pileatum Ach.

One example was found on a rock in Carlisle. I am indebted to Dr. Farlow for the determination.

12. Cladonia papillaria (Ehrh ) Hoffm.

Through the kindness of Miss Carr, I am able to report this species from Sudbury, where she found it in several places. The determination of her specimen was corroborated for me by Dr. Farlow. Mr. Walter Gerritson, of Waltham, allows me also to report it from that township, where he has col- lected it on barren soil. Mr. Merrill determined his examples.

Since the Middlesex Flora was published the genus Cladonia has under- gone such a revision that the status of its species in the country is exceed- ingly difficult. The following have been collected in Carlisle and Concord, and may be included or not in those given for the region under less specific names or by other titles. For the determinations I am indebted to Prof. Bruce Fink and Mr. Merrill.

MICROSCOPICAL TECHNIQUE.

Many persons who have to use the microscope in their studies find it desirable to do much of the work at night and to such a good working light is not an unimportant matter. A very excellent light may be arranged by the very simple expedient of placing a piece of white cardboard six or eight inches behind a incandescent electric lamp and using the reflection f*rom its surface. A piece of botanical mounting paper answers the purpose nicely and for the moss student is usually at hand. If an electric light is not avail- able a good student lamp may serve in place of it. Such a light is almost if not quite as good as daylight reflected from a white cloud which, of course, has no superior. Sometimes it is well to shade the lamp in front by another small piece of cardboard. This suggestion may be old to many readers of the Bryologist, but those who have never tried it will easily solve the prob- lem of a desirable light for microscopic work. J. P. Naylor,

LICHEN NOTES No. 4.

A Study of Umbilicaria vellea and (Jmbilicaria spadochroa.

G. K. Merrill.

The statement made by Nylander (Synopsis, Pt. II, p. 9) that sterile specimens of U. vellea are not easily determinable, is one tp surprise an American student of lichens. The late Prof. Tuckerman long furnished us with our opinions on the taxonomy and specific delimitations of lichens, and his treatment of the Umbilicaria in Synopsis presented no difficulties what- ever, once one came to know the commoner species. Tuckerman cites only two species of ash-colored Umbilicaria for America, U. vellea (L.) Nyl. and U. hirsuta (Ach.) Stenh. Of these two, U vellea only is common, and our students have unhesitatingly referred all specimens of the ash-colored, whit- ish or brownish-ash-colored Umbilicaria, when black and hirsute below to this species. If, as Nylander asserts, specimens of U. vellea must be fertile to be identified with accuracy, it is evident that the distinguishing characters are apothecial, not thalline. This deduction is confirmed by the author’s statement of its resemblance to U. spadochroa and of a difference in spore measurements. The spores of U, vellea are said to measure 9-12 by 6-7 fi, those of U. spadochroa 18-29 by 10-18/*, a very considerable discrep- ancy.

Nylander credits U. vellea to Acharius, Methodus, p. 109, citing the amended dianogsis for the species found in Lichenographia Universalis, p. 673, as excellent. No mention is made of U. vellea as being a Linnsean species, nor is allusion made to its citation in the Acharian Prodromus. This is the more remarkable as Acharius himself duly credits the plant to Linnaeus, with the synonym of Lichen velleus. It is thought that but few of the early lichenists rightly understood U. vellea , even Hoffman who was responsible for the generic name of Umbilicaria, and numbers of its species* miscalled and figured U. polyrrhizos for U. vellea in his Plantae Lichenosae. However the name figures in several of the eighteenth century floras. It is apparent on comparing the descriptions of U. vellea and U. spadochroa in the Prodromus and Methodus, that Acharius had no true conception of either species. The diagnoses are much alike, some of the characters at a later period held to distinguish the two, being used indiscriminately. Acharius must have been acquainted with U. vellea as found in the Linnaean herbarium, and it is really difficult to understand his uncertainty unless a word from Wainio explains,

In a paper entitled “ Revisio lichenum in herbario Linnsei asservato- rium,” the latter records p. 7. that the specimens of Lichen velleus as found were sterile, and thus uncertain. Sterility or fertility counted for but little to the early species makers, the grosser differences at once apparent seem- ing to their minds the surer guide. While on the subject of the Acharian comprehension of U. vellea , it will be of interest to cite from ‘Leighton’s “ Monograph of the British Umbilicariae,” the results of his examination of authentic specimens of U. hirsuta and U. vellea , communicated by Acharius to Borrer, and found in the latter’s herbarium. Leighton declares that the

two appear to be identical, that tf. veiled only was fertile, with spofeS double the size of U. polyrrhisa or 18-22 by to-12 /d. If these Specimens from Archarius were identified before he reached definite conclusions regard- ing the specific limits of If. veiled , comment is Unnecessary. But if they were determined on characters set forth in Li. tjm. p. 673 1. C. there may be several inferences. Either Nylander is in error and if. vetted should hdvi large spores : or large spores are concomitant to both tf sPddockrod and tf. veiled : or, the other physical characters of one or both plants may be incon- stant, or finally the arbitrary separation of the two on sporal or other differences may be without justification. The delimitation of two lichens identical in other respects, because of difference in size of the spores is abhorrent to a conception of natural species. The thallus of an ash-colored Umbilicaria sp. on which are ultimately developed the apotheeia of tf. veiled and tf. spddochrod is none the less specifically one or the other despite its infertility, and if the thought is carried further until the larger spores of tf. spadochroa have assumed their full size, may it not be proper to call the species U. veiled ?

An endeavor to learn something of V . veiled from the writings of Linnaeus is frustrated by the terseness of his descriptions. In “ Species Plantarum,” 3d Edition, p. 1617, Lichen velleus is described as “ Lichen foliaceus umbilicatus subtus hirsutissimus ” and quoting himself in “FI. Lapp.” the author amplifies with “ Lichen folio subrotundo feltato margin fere integro, subtus inaxime hirsutus.” Linnaeus cites the illustration in “ Historia Muscorum of Dillenius,” Fig. 5, pi. 82, as representative of the form, and the Rev. J. M. Crombie proves to us that the Linnaean guess or Dillenian drawing were both good. In his “Lichens of Dillenius Historia Muscorum, illustrated by his herbarium.” Crombie says “ that the specimen of U. veiled in Herb. Dill, to which is attached the descriptive label of ‘ Lichenoides coriaceum latissimo folio umbilicato et verrucoso’ is sterile, and “the specimen of which the figure is not at all good, represents a very large and old state of the species.’ ”

One wonders how Crombie recognized a “ sterile” .state of if. veiled with the certainty indicated by his words, but that must remain a mystery so far as present knowledge helps. It may be pointed out as a curious considera- tion at this juncture that while type specimens of U. veiled (L. ) Nyl. have been preserved, no one can state with definiteness whether they are repre- sentative of veiled or spddochrod as those plants are now understood. Acharius in Li. Um p. 673 1. c. was first to make the effort of clearly mark- ing limits for each of the two species. It is conceivable from Nylander’s words (Syn. 1. c. ) that the Archarian dissociation impressed him as being fundamental. Th. Fries, “ Lichenographia Scandinavica,” considers that while Acharius rightly knew U. veiled , his recognition of spddochrod might be questioned. Whatever view is taken of the Acharian conclusion, the uselessness of going behind his amended diagnosis had been made apparent.

As the early writers delimited species almost entirely on macroscopic characters, it will be a matter of interest to learn if possible in what respect,

•85-

and to what degree the two species — very near one another as all have agreed— were found to differ. There seems no better way to accomplish this end, than to take the diagnoses of Archarius, E. Fries, Schaerer, Nylan- der, Th. Fries and Tuckerman for a basis, and frame a composite description for each species. Such an abstract would naturally comprehend all of the individual variations noted by the several observers for each form.

U. veiled : — Thallus ash-colored, brownish, greenish or whitish ash- colored or whitish-pruinose ; ample to large ; leathery, rigid or thickened ; smooth, scarcely elevated-punctate, or minutely rimulose-areolate ; mono- phyllous and irregularly repand. Thallus below, brownish, brownish-black, blackish, or black ; granulose-unequal, subhirsute, hirsute to very hirsute. Apothecia marginal, (sessile, Ach.) (patelliform, E. Fries), superficial, appressed, plane, small, margined, becoming convex, immarginate, or fin- ally excluding the margin, or with a tumid margin ; concentrically or gyrose- plicate, and E. Fries states that the disc may be papillose.

U. spadochroa : — Thallus greenish, brownish, or whitish-ash-colored, or quite white; small to large; rigid, subcoriaceous and thickened; smooth or elevated-punctate; monophyllous. Thallus below, pallid-ash-colored, brown- ish, brownish-black, blackish or black: areolate-granulate, denudate, exas- perate, scabrid, papillose, lacerate or more or less hirsute. Apothecia marginal, plane, subsimple appressed, lecideine, the margin thickened or subpersistent, contracted or even extended, smoothish or sparsely gyrose- plicate; papillate from the center of the disc, or the verrucae deficient, when there may be a central depression.

A comparison of the foregoing descriptions will disclose that so far as color of upper surface is concerned the two species are much alike, . and the same may be said of the size, texture and lobation. The upper surface of U. spadochroa is said to be smooth (Th. Fries) elevated-punctate and deli- cately rimose (Ach. Li. Um. p. 229) but the latter describes both species as elevate-punctate, and the rimulose-areolate characteristic is known to be a product of age and habitat. The under surface presents greater dispari- ties, unimportant in color, but marked in other respects. It will be noted that U. veiled as described is usually hirsute with the range of variation from “granulose-unequal” (Nyl. Syn.) to very hirsute; and that U. spado- chroa as mentioned is not commonly so well provided with rhizinae, may even be “denudate” (Schaer. Eu.) or conditioned variably to “densely rhiz inose ” (Th. Fries Li. Scam). In apothecial characters much diversity is shown, according to Acharius (Li. Um. p. 672) U. vellea has constantly plane marginate apothecia with the disc concentrically plicate : while those of U. spadochroa are said to be marginal, usually plane, the margin thick- ened and contracted, the disc not uncommonly plicate and solitarily papil- late from the center. E. Fries (Li. Eu. Ref.) asserts that the apothecia of U. vellea may be papillate, a statement only explicable by the inference of his having mistakenly described U. spadochroa. The plicate of the apothecia are indifferently concentric or gyrose ; and that organ may be appressed in both species.

•86-

In brief the differences between the species as here summarized are really inconsiderable, except that one of discordance in apothecial conformation. This factor in itself would scarcely seem of sufficient importance to sepa- rate the two, but Nylander and others have found that the papillate apothe- cia of U. spadochroa afford large spores. An instance of crude botany reinforced by modern histology. With Nylander first to point out sporal dif- ferences, the labors of other lichenists seemed to become confirmatory, if Hepp is excepted. In the latter’s work on the spores of European lichens, are figured and micrometrically recorded the spores of U. vellea and U. spadochroa as examined in the Exsiccati of Moug. & Nest, E. Fries and Schaerer. In plate XXXIV, fig. 306 Hepp’s Sporen, the spores of U. spado- chroa (Ehrh.) Ach. Li. Um. p. 229, are alleged to be illustrated. The figures and measurements are derived from examination of E. Fries, Li.Suec. Exs. No. 130: Moug. & Nest, Exs. Nos. 540 and 746, and Schaerer, Exs. Nos. 141 and 142. All have small spores, vis. 9-1 1 by 5-8/1, and by modern interpreta- tion belong to U. vellea and not U. spadochroa.

Nylander avowedly, and Th. Fries inferentially based their diagnosis of U. spadochroa on the Acharian conception, and both the former definitely accept the papillate apothecia as distinguishing. Is it not strange that the various specimens from those exsiccati examined by Hepp, doubtless all determined on the Acharian data, and conjecturally all provided with the papillate apothecia of the species, should have yielded small spores ? It is reasonably certain from the description, that U. vellea of E. Fries (Li. Eu. Ref.), is U. spadochroa as now understood. If No. 130 of Fries Exs. Li. Luec. is representative of that author’s var. b. spadochroa as may be inferred from the text, with its determination based on the Acharian conception, then Nylander’s assumption of small spores for U. vellea is really inexplicable. Schaerer (in Eu.) affirms No. 130, Fries Exs. to be equivalent to U. cirrhosa Hoffm., and Wainio (Revisio Lich. Hoffmannianorum, p. 16), finds the speci- mens of U. cirrhosa iu Hoffman’s herbarium to be U. spadochroa (Ehrh.) Ach.

Some one has erred, but on whom shall the burden rest ? No. 141 of Scharer’s Exs. is his form d. rupta of U. vellea var. spadochroa , and No. 142 represents his form cinereo-rufescens. Schaerer cites the latter as synonymous with U. spadochroa DC., U. vellea Ach. , and Lichen valleus Ehrh. ! Plate XIV, fig. 117 of Hepps’s Sporen is said to figure the spores of U. vellea (L.) Ach. Syn. p. 68. The specimens examined were from Moug. & Nest, Exs. No. 344, and Schaerer’s Exs. Nos. 137, 138, 139 and 140. All have large spores viz. 18-24 by 8-13//, and several numbers by Nylander and others would be referred to U. spadochroa. Schaerer lived a little early to fully avail himself of the manifold advantages of the compound microscope, and he variously distributes the above cited examples to his Enumeration, they appearing to have been very dissimilar externally. No. 344 Moug. & Nest, Exs. is referred to his U. vellea var. a, hirsula . U. hirsuta as now understood has spores of 9-12 by 4-8//, or small. Nos. 137, 138, 139 and 140 of his Exs. Schaerer defines as form b, vellei-formis , f. c. vulgaris , f. d.

-87-

abortiva, and f. e. rupta respectively of his U. vellea hirsuta. From the descriptions of Nos. 137 and 139 (Eu. 1. c.) both can be easily placed with U. spadochroa on their macroscopic characters, the other two are doubtful how- ever.

Reviewing what has been written, it will be perceived that each author prior to Nylander’s Synonymy, in dealing with U. vellea and its ally, became a law unto himself with respect to their specific limits. It is ques- tionable if Nylander himself constituted his diagnosis of U. spadochroa on a clear knowledge of the early herbarium examples, although no man had ampler opportunities to acquire information. It is conceivable that U. spa- dochroa as considered in Synopsis is a purely arbitary creation, based on the observation that large spores are concomitant with papillate apothecia. If this were an established fact, with no ascertainable record of deviation, a fairly good warrant for specific rank would ensue. The writer has found, however, through examination of an extended series of American ash-colored Umbilicariae that specimens are not uncommonly met with, provided with distinctly papillate apothecia which do not yield large spores! In fact the measurements accord with those of U. vellea. As the specimens are black and very hirsute below and bear every other characteristic of the species they may with assurance be referred to U. vellea.

In the final analysis it is seen that all the characters of U. spadochroa except its large spores may be shared by U. vellea. On this distinction alone it is believed that the form scarcely deserves specific rank, and should be reduced to a variety or modification of the older U. vellea. No. 198 Decades of N. Am. Lichens, issued as U. spadochroa Hoffm., in our copy affords small spores only, and being unprovided with papillate apothecia should be considered as representative of U. vellea. Prof. John Macoun collecting in 1905, on the St. Lawrence below Quebec, found an Umbilicaria sp. which in the specimen submitted to the writer, offers characteristics at once suggestive of U. Dillenii Tuckerm., on the one hand, and U. vellea on the other. The plant is brownish at the circumference as in U. Dillenii , whitish-pruinose at the center as in U. vellea , and like the latter hirsute below. The apothecia and spores are those of U. Dillenii, but the upper surface is rimulose-areolate as in U. vellea. Prof. Macoun suggests that the form be given a varietal name, but it is hardly thought desirable to do so at present.

If any members of the Sullivant Moss Chapter have collected the lichen, Solorina saccata, I shall be very glad to hear from them and to ex- change specimens with them. I should also be glad to hear from any one who has specimens of Solorina saccata in his herbarium, giving me the local- ity where they were collected.

Address, Mrs. Caroline W. Harris,

125 St. Marks Avenue, Brooklyn, N. Y.

It has come to the notice of the officers of the Chapter that in several instances stamped envelopes have been sent requesting the current “Offer- ings ” and have met with no response. It is hardly possible that the same member would have his missive go astray more than once. It would also seem to be the obvious thing to do if a request comes after the material is exhausted for the person offering, to use the envelope to reply stating the fact.

The December meeting of the S. M. Chapter, in connection with the A. A. A. S., will be held either at the New York Botanical Garden at Bronx Park, on Saturday afternoon, Dec. 29th, or at Columbia University on Monday afternoon, Dec. 31st, as the other meetings of Botanists will be divided between the two places at the times, stated.

The November number of this journal will contain the definite informa- tion as to place and date and hour of meeting.

FURTHER NOTES ON CLADONIAS. VIII.

Ciadonia botrytes, Cladonia caespiticia, and Cladonia delicata.

Bruce Fink.

There may be considerable doubt about a very close relationship between the species considered in this paper and those disposed of in the last one (Bry. 9, July, 1906), and it may also be doubted whether the first species to receive consideration below stands very near to the second and third. Both Tuckerman and Wainio have placed Cladonia caespiticia and Cladonia delicata in close relationship, but both have seen fit to remove Cladonia botrytes far from these. Nor have these authors placed Cladonia botrytes near Cladonia mitrula, to which species it bears enough of superfi- cial resemblance so that one might easily pass the former species over as a small form of the latter, growing on wood. However, the Cladonias exhibit a most bewildering series of relationships, combining the various species in an inextricable network, and all arrangements must be regarded as more or less artificial. Doubtless the words of Dr. L. M. Underwood, regarding a similar difficulty in the classification of the Agaricales, or gill fungi, apply here, as follows: — “A part of the difficulty, however, is due to the fact that we have here an extensive evolution of comparatively recent origin in which very many of the steps of the progression are still inexist- ence” (Moulds, Mildews and Mushrooms, p. 129). Again, both Tuckerman and Wainio give considerable prominence to the paler fruit, in removing Cladonia botrytes far from Cladonia mitrula. However remotely related the two species may be, the difference in color can have little weight in determining.

But passing the first species considered below, we are on surer ground, lichenists generally admitting the close relationship of the other two species' and that of both of these to Cladonia squamosa , which species we will con- sider’in the next paper of this series.

Finally, the writer is willing to let comparisons of the two descriptions, and better the study of specimens, speak further for the relationship of Cla- donia botrytes and Cladonia mitrula, the latter description to be found in the last paper of this series and the former to follow immediately.

Plants from British America, New York, Virginia, Wiscon- sin and Louisiana are referred here by Dr. Wainio in his Monograph, and he has also determined the plant for the writer from Minnesota, where it is found on dead coniferous wood throughout the northern portion of the State. The “pale fruited form” of Cladonia mitrula distributed as No. 187, “ Lichenes Boreali-Americani, ” seems quite close to the present species, but on submitting the number to Dr. Wainio he agrees with authors of Lich.

A STUDY OF TETRAPLODON AUSTRALIS.

By I. Hagen.

Tetrciplodon australis Sulliv. & Lesq. has been very little studied. This fact is accounted for by the circumstance that the specimens in the various herbaria were collected for the most part too late in the season and hence in a condition unfavorable for study. I am, however, happily in pos- session of fine material collected at my request by Mr. Severin Rapp, at Sanford, Florida, during the month of December, 1904. An examination of this material has furnished the details which enable me to determine its rela- tionship decisively.

Why the authors of the last half of the nineteenth century placed this species in the genus Tetraplodon, I have never been able to comprehend, and a study of Mr. Rapp's collections has shown me that this genus is pre- cisely that one of the sub-family Splachnae with which it has least in com- mon. There are important differences in nearly all parts of the sporophyte: — the seta is soft and hyaline in ' T. australis , solid and colored in the other species of the genus ; the columella is exserted in the former, included in the latter; the teeth which are bigeminate in the other species of Tetra- plodon are geminate only in T. australis , and, in addition, in this latter they have central cavities, though solid in the other, a condition which is due to a difference in the number of layers of cell tissue from which they originate: the calyptra is elongated below the operculum, cucullate or rarely campanulate in true Tetraplodon, while it is conical and covers only the top of the operculum in T. australis.

Nor can our species be Haplodon, because of its exserted columella and geminate teeth with interior cavities. There remains then only the genus Splachnum, and with this it agrees in all the characteristics cited, as separa. ting it from the two other genera of the same sub-family. But if the descrip- tions of the stem structure of Splachnum found in literature be compared with the facts noted in studying the stem of our Tetraplodon there appear to be differences. The cross section of the stem in T. australis shows false leaf-traces, while in the case of Splachnum there are said to be true leaf, traces. But the information furnished by literature upon this point is not exhaustive and the generic difference between Splachnum and Tetra- plodon australis actually non-existant. Lorentz, who had studied the structure of the stem in the two Splachnums, S. sphaericum and S. luteum , says after describing it in 5. sphaericum (Flora, 1867, p. 537): “We

find this structure of the stem also in the following species of our genus, v i. e. S. luteum, “not, however, in Tayloria nor in Tetraplodon. It is per- haps not too bold to assume that this characteristic occurs also in other species of the genus and furnishes an excellent generical distinction from the other Splachnaceae.” This general conclusion made by him with reserva- tion, is reproduced without restriction by Limpricht. (Laubm. FI. Deutschl. Oesterr. u. d. Schweiz. (II. p. 164.). But if this is true in the species exam- ined by Lorenz, it is however incorrect in 5. ampullaceum and S. vasculo-

-93-

sum , both these species having false leaf-traces in the stem precisely as in T. australis. Here we see the danger of generalizing too far.

T. australis agrees exactly with certain Splachnums in another charac- teristic taken from the vegetative parts, namely in the structure of the costa. It is Lorenz again who has given some hints on this subject. According to him the costa of the Splachnaceae is composed of two large ventral cells (“guides”), of a certain number of large dorsal cells, and of a central cellular body whose principal element and characteristic is a bundle of thin- walled, angular cells of the kind he has called “comites in addition, one usually finds between these “comites” and the large dorsal cells a larger or smaller number of cells which he designates as “intercalary” cells, formed sometimes like the guides, sometimes difficult to distinguish from the “comites,” sometimes thin-walled, sometimes rather incrassate. In Tetra- plodonshe observes that these intercalary cells are present, at least in the most developed part of the costa, and that they are nearly stereid ; as regards Splachnum he describes the same structure in S. sphaericum, while in S. luteum he finds a bundle of “comites” surrounded by numerous, rather large, polygonal, thin- walled cells. In S. vasculosum and in S. ampullaceum I have observed a little different structure: the “ comites” form here a band, which extends between the ventral and the large dorsal cells along the median line of the costa; at each side appear, usually, some large rounded, thin-walled intercalary cells, having nearly the aspect of the ventral ones. These intercalary cells are wanting, however, in 5. ampullaceum , in the upper part of the leaf where the central cellular body is con- sequently represented by the “comites” alone. The same structure is found in T. australis , (and likewise in Haplodon) in all parts of the costa which is composed here also of “ comitesT surrounded by the large ventral and dorsal cells. We have here another characteristic which distin- guishes T. australis from true Tetraplodon and at the same time connects it with Splachnum ampullaceum.

That T. australis belongs to the genus Splachnum is thus set beyond doubt, and it becomes apparent that it is S. ampullaceum with which it is most nearly allied. This relationship is in fact so close that without incroaching on its specific claims, we can characterize it as an S. ampulla- ceum with hyaline seta, apophysis reduced to a minimum and narrower, deeply dentate leaves.

It goes without saying, that this conception should be expressed in the name. In transferring it to the genus Splachnum, however, I take the advantage of the occasion to restore to it the oldest specific name, so long unnoticed and revived only in 1883 by Lindberg, who was convinced by his studies of the herbarium of Dillenius that the type of Phascum caulescens L. is the same plant as Tetraplodon australis Sulliv. & Lesq.

Regarding the citation from Linnaeus it should be noted that his Phas- cum caulescens of Sp. pi, is founded on Dillenius’ plant, but in reality he did not know this species as Schimper’s examination of his herbarium shows Journ, Linn, Soc. XI, p. 246), According to this distinguished bryologist, a specimen labeled “ Phascum caulescens lectum in Lapponia cit, Dillen, 550, T. 85. f. 15,” belongs partly to Splachnum angustatum , partly to Cynodon- tium Bruntoni : and another specimen of which Schimper cites the label as follows: “Splachnum — North America, sec. Smith, Splach. caulescens

Dicks,” is, according to him, a Tetraplodon angustatus forma gracilescens , I interpret the latter label as if the word “Splachnum — ’’alone is due to Linnaeus, the rest added by Smith, who had bought his herbarium. How- ever that may be, it follows from the examination of Schimper, that Linnaeus did not have a correct idea of Phascum caulescens , and that the name does not refer to his herbarium but exclusively to Sp. pi. Dickson on the contrary seems to have correctly recognized the plant in question: he says in his “ Observations on the genus of Porella and the Phascum caules- cens of Linnaeus”: “The Splachnum which I received at the same time

with the above when compared with Dillenius’ specimen, proved to be the Sphagnum figured on Tab. 85, f. 15 ; the figure is remarkably stiff. This is made a Phascum by Linnaeus, but with equal impropriety, it being a true Splachnum.” Opdal, Norway, May, 1906.

VANCOUVER ISLAND BRYOLOGY, No. 1

Dr. John W. Bailey.

Vancouver Island, which lies off the west coast of British Columbia, is mountainous, well wooded with evergreens on the highlands, and with alder and maple in the bottom lands. During seven months of the year it is shrouded with fog and bathed with gentle rains on the coast, while heavy snows fall in the interior. At this time every hillside depression becomes a rivulet and evfery ravine a rushing mountain torrent. On account of the amount of moisture in the atmosphere and the equibility of the climate, it presents an ideal habitat for many species of mosses, nearly all of which fruit abundantly. There is but little limestone on the island. Conglomer- ates, sandstone and shales are found associated with the coal deposits in the neighborhood of Nanaimo and Cumberland on the East Coast. My collect- ing was done at the latter place, forty miles south of the fiftieth parallel of latitude.

Cumberland is near Comox, a locality which Macoun visited some years ago for bryological purposes. Thirty miles to the south the extinct crater of Mt. Arrowsmith rises to an altitude of 5,600 feet, from whose sides and summit Macoun brought many interesting mosses. In this region the tree mosses are the first to attract one’s attention. The maple trees ( Acer macro- phy linin') are covered with great mats or pillows of them. Neckera Men- ziesii prefers the trunks of these trees while N. Douglasii is found on the upper branches, though they grow intermingled. Nothing bryological is handsomer than the delicate orange colored capsules of N. Douglasii lying among the pale green leaves of the plant. N. Douglasii prefers moist shady localities for developing its sphorophyte. N. Menziesii fruits at low alti- tudes whereever found. Its pinnae are a coppery red color, the capsule inserted and dark red in color.

Antitrichia curtipendula gig ante a occurs in great cushions, more often on the horizontal limbs of trees. It grows on the evergreens as well as on the deciduous trees. The stoloniferous portion of the plant bears the cap- sule and it, like Neckera Douglasii, prefers dark cool situations in which to develop it. In late winter or early spring the growing tips of this moss are a golden yellow and the sombre forest takes on a new aspect, when these fresh yellow points begin to cover the brown cushions of previous years. I found very little Antitrichia California, and judged that Cumberland was out of its range.

Eurhynchium stoloniferum is found near the coast, at higher altitudes it disappears. Probably none of our coast mosses is more variable. It grows on wood or rocks. There are four distinct forms of it growing about Cum- berland : the stoloniferous (var. sub stoloniferum ) in long hairy masses on limbs of trees ; a very large form growing in dark damp woods; a smaller tawny colored form growing on rocks in canons but not stoloniferous. This hung in long festoons over the rocks; a julaceous form, which when dry simulated Scleropodium obtusifolium , found on rocks in brooks wet by the spray of the rushing water, growing just above high water mark. Although

—9&—

the various forms are so different in appearance, under the microscope the leaves are identical. The coarse doubly dentate margins, the strong mid- rib, and the punctate cells in the lower leaf angles are the same in all.

Claopodium crispifolium is common on rocks and trees. It is indistin- guishable from C. Bolanderi except under the microscope. C. Bolanderi is found on rocks, while C. Whippleanum is found on rocks and soil and resembles Plagiothecium elegans.

Dendroalsia abietina is rare. Besides E. stoloniferum three Eurhyn- chiums are common, Oreganum, praelongum with its variety Stoke sii, and fallax. E.fallax was to be found only at high altitudes. Growing at lower altitudes and hidden away about the roots of cedars is to be found a large Eurhynchium with variegated copper colored pinnae. One never obtained very much of it as it was hard to find. It belonged to the blunt leaved division of Eurhynchia. Its capsule was a beautiful chestnut red.

Plagiothecium undulatum is plentiful in proper locations. On humus or rotton logs, and P. denticulatum is common.

The Heterocladiums, H. heteropteroides and H. procurrens , are high- land mosses and are found on rocks. On vertical rocks, where there is plenty of water, H. heteropteroides assumes the variety filescens. On flat rocks it grows with short pinnae and fruits freely. H. procurrens is easily recognized by its complanate leaves and feathery pinnae and at altitudes of one thousand feet it becomes the commonest of the rock mosses.

Amblystegiums are rare in my locality though several are accredited to the island. Seattle, Wash.

NOTES ON THE MOSSES OF WATERVILLE, NEW HAMPSHIRE.

Annie Lorenz.

The settlement of Waterville, N. H., lies in the Mad River Valley, at 1550 ft. altitude, north of Sandwich Dome, with Mt. Osceola (4352 ft.) forming the northern end of the valley. Very little collecting appears to have been done there. The only specimens seen by the writer are a few in the hotel herbarium, collected by Mrs. Helen E. Jelliffe in August, 1896.

Waterville is a granite-and-drift region, the absence of limestone making peculiar gaps in the flora, phanerogamous as well as cryptogamous. The most unusual’place in the region is the ravine known as the “V’’ on the southern slope of Mt. Tripyramid. It consists of two steep granite slopes, meeting at an angle of 90 degrees, and running west by north. The south- ern side has a rich cover of Sphagna, various Hypna and Hylocomia, Philo- notis, Scapania, and such, all heavily fruited. The best thing there is Blindia acuta (Huds.) B. &S. in good fruit.

The summit of Mt. Osceola is a crumbly trachytic granite, cushioned with Polytrichum strictum Banks, with Dicranum fuscescens Turn, and D. longifolium Ehrh. on the scrub balsam, although Lophozia gracilis (Schleich.) Steph. is really the principal product. Sphagna are abundant, but only casually examined by the writer. Andreaea petrophila Ehrh. is com-

-97-

mon, not only on the summits, but on the rocks along the brooks, and usually heavily fruited, particularly on the north sides of the rocks.

One of the most interesting features of the bryophytic flora is the occur- rence of Dicr anodontium longirostre B. & S. exemplifying, as it does, the writer’s theory as to its habitat,— namely, that it grows near water not above 45 degrees temperature. Of three stations, the largest is at Tyler’s Spring (45 deg.) where it grows very abundantly on the banks near by, which are full- of rotten wood. The second station is in a similar place by a spring (40 deg.) between the two Greeley Ponds: the third station is on a rock, near a cold stream feeding the upper Greeley Pond. Dicranodontium is instantly known by its intense green color, and its moulting when touched. “ Folia — quam maxime fragilia.” (Bry. Eur. ) The writer has so far always found it sterile in New England : it prefers banks full of old wood, but is sometimes found upon rocks.

On account of the exclusively siliceous formations, the Tortulaceae- Saelania, Fissidens, etc. are lacking. Bryum is mostly absent, the lack of B. proliferum (L.) Sibth., being rather noticeable, but Pohlia nutans (Schreb,) Lindb., and P. elongata Hedw. are frequent.

Mnia are abundant, but of few species. Trematodon ambiguus (Hedw.) Hornsch. is frequent, in dry fields, or by sandy roadsides. The Poly- trichaceae are well represented, with five species of Polytrichum, three of Pogonatum, and one Catharinea.

The sphagnum bogs are almost pure stands, without the Camptothe- cium,the various Hypna, scorpioides L., stellatum Schreb., revolvers Swz. Thuidium B landowii (W . & M.) B. & S. etc. of calcareous bogs. Homalia / amesii Sch. is quite common on the north and northwest sides of granite boulders, also P lagiothecium Muellerianum Sch. in similar but more ele- vated situations.

Of the Marchantiaceae, only Marchantia and Conocephalum appear. Diplophylleia taxifolia (Wahl.) Trevis. is rather common along the bases of rocks in stations above the level of the valley itself. Lophozia gracilis (Schleich.) Steph. is ubiquitous, and L. incisa (Schrad. ) Dum. is somewhat frequent on old stumps, L. barbata (Schreb.) Dum. is apparently absent.

The numerous trout streams have an abundant, but not particularly varied flora, Scapania, Fontinalis, Rhacomitrium aciculare Brid., Hypnum eugyrium B. & S., H. dilatatum Wils. with Marsupellae in the upper reaches.

In general, the list makes a good showing for a non-calcareous region, although it cannot compare with one in which both calcareous and siliceous formations are found.

These are merely notes of a several-week’s stay, to be regarded as pre- liminary only, and not as exhausting the possibilities of a region which will well repay further exploration.

Stephani has recently reduced to this species, as a synonym, Jimger- mannia Mildeana Gottsche,* a form which most European writers have con- sidered distinct If this reduction is made, and it certainly seems justifiable, then the writer’s J. Novae-Caesareae ,f although recognized by Stephani, should apparently share the same fate. Accepting L. Marchica in this broad sense it is now known from three New England stations: Beach Mt., Mt. Desert Island, Maine ( E . L. Randy. Woods Holl, Massachusetts (. A . IV. E.)\ East Haven, Connecticut (A. IV. E). The species is essentially a bog-plant and is commonly found creeping through tufts of Sphagnum; in some cases however the plants may be completely covered with water, while in other cases, especially when growing in sandy bogs, they may be exposed to dry- ness. The plants vary markedly according to the amount of water which they receive, a liberal supply producing elongated stems with scattered leaves while a scanty supply produces short stems with closely crowded leaves. The cell-strucjbure is also variable. Protected and shaded leaves show thin and delicate walls, while leaves exposed to the sun show thickened yellowish walls with more or less conspicuous trigones. A single leaf in fact may show these variations in cell-structure. The dark purple stems which are characteristic of typical L. Marchica are paler in some of the other forms and sometimes show no trace of purple: in other cases the color is limited to the bases of the rhizoids and the adjacent parts of the stem. Underleaves are occasionally present in all the forms among the stem-leaves, but they are often very few in number and have the appearance of being abnormal or adventitious. Floral underleaves or bracteoles are of course invariably present. Plate IX. Figs. 1 — 4.

By most American authors this species has been referred to J. excisa Dicks., and it is described under this name in the sixth edition of the Manual. It is probable that the true J. excisa was a composite species including among others the J. bicrenata of Schmidel, but there is so much uncertainty about it that some European writers have given up the name altogether while others reserve it for J. capitata Hook. {==/. intermedia Lindenb.), a very different species from Lophozia bicrenata. J. capitata is described in the Manual as J. excisa , var. crispa Hook, and has not yet been definitely reported from New England. L. bicrenata on the contrary is not uncom- mon and is usually found growing on the earth in woods or along their bor- ders. It has been collected from near the coast to an altitude of 5000 ft. in the White Mountains and does not vary markedly in different localities. To the description given in the Manual it may be added that the inflorescence is paroicous and that the plants, which are usually more or less tinged with red- dish, commonly give off a peculiar aromatic odor. New England specimens from the following stations are in the writer’s herbarium: Crawford Bridal Path and Jackson, New Hampshire (A. TV. E .): Andover, Vermont ( IV. G. Fartow): Woods Holl, Massachusetts ( A . IV. E .): Orange and Hamden, Connecticut (A. IV. E.). Plate IX. Figs. 5—9.

In a note on I^ophozia bicrenata * the writer made the statement that the true L. excisa , with which L. bicrenataha.s been confused in North America, had not been definitely reported from New England. The specimens recorded above, however, were already collected but through an error had been referred to another species. L. excisa agrees with L. bicrenata in its paroicous inflorescence. It is distinguished by its larger size and more deli- cate texture, the leaf-cell being thin-walled, except for the small trigones at the angles, instead of being uniformly thick-walled throughout. It also lacks the brownish or reddish pigmentation and the peculiar aromatic odor which are usually associated with L. bicrenata. In general appearance it bears considerable resemblance to small forms of L. ventricosa. Its paroi- cous inflorescence will at once separate it from this species, and it is usually easy to recognize the perigonial bracts, even after the antheridia have dis- appeared, by the small pocket or indexed tooth at the antical base. In spite of the uncertainty connected with the original J. excisa of Dickson, most recent writers associate this name with the present plant. Plate IX. Figs. 10—13. ‘ To be Continued. New York City.

NOTES ON POLYTRICHUM COMMUNE.

J. Franklin Collins.

(Reprinted by permission from “Preliminary Lists of New England Plants” in Rhodora,

8: July, iqo6.)

No species in the list has been more difficult to interpret than Poly- trnchum commune with its many forms and variations. The species, as described by Dillenius, Linnaeus, Bruch and Schimper, Dixon, Limpricht, Roth, Lesquereux and James, and others, appears to be much less common than has been generally supposed. It is impossible at the present time to place satisfactorily some of the forms of this species, yet certain conclusions have been reached which would seem to justify preliminary publication, especially as it is very desirable that the attention of collectors be called to the necessity of getting abundant material from various habitats and locali- ties—more particularly perhaps from bogs, swamps, and other wet places. The writer would be very glad to get specimens from any and all parts of the country— especially from New PJngland — with a view of attempting to clear up the uncertainty in regard to several varieties and forms, the identi- ties of which are at present too problematical to appear in the above list. It is quite possible that the interpretation of P. commune, as outlined here, may have to be revised when more material is at hand. Briefly, P. commune , as here restricted, is the fairly tall plant of moist shaded places with the game- tophyte normally at least io cm. high, stems mostly simple, leaves remote, the upp-er free part (blade) about i cm. long and appressed when dry but hav- ing the apex recurved and the shining leaf-bases conspicuous; seta 6-n cm. and capsule 5 mm. (4-7) long ; calyptra golden brown.

The var. perigoniale is a smaller plant (-4-8 cm. high) of drier and more exposed situations, with leaves smaller and more crowded, so that, when dry and appressed, the leaf-bases are ordinarily not seen: seta and capsule shorter (the latter 3-4 mm. long). As a rule this variety is darker colored in all its parts and more compact than is the species, suggesting a more xero- phytic plant. The perichaetial leaves, although usually more conspicuous and more prominently hyaline, are not necessarily any larger than in the species. This variety undoubtedly occurs in Vermont though no record of its occurrence there has been found.

The var. uliginosum is just such a variation as might be expected in a very moist, well shaded, and humid situation; that is, with elongated and more or less flexuous stems, longer and most distant leaves. In the dried state a very pronounced character is the abruptly squarrose upper portion of the leaf, the apex of which is often somewhat recurved or even circinate. It should be expected in all the New England states.

From an examination of some thousands of leaf sections of P. commune and its allies during the past year it is quite evident that there is much more variation in the lamellae than might be expected from reading standard descriptions; for instance, the end cells in sections may vary from strongly crescentric to circular in the same leaf, depending respectively upon whether the section is cut near the middle of the leaf or down near the sheath. Like-

102 —

wise, the heights of the lamellae vary. Again, the lamellae of immature leaves differ from those of mature ones. The leaves and lamellae of new shoots differ from those of the old shoots when the amount of humidity or soil mois- ture is altered. This can easily be shown experimentally by transferring a plant from a moderately dry situation to a dish of water under a bell jar and later comparing the leaves of the new shoots with those of the old. The thickness of the outer wall of the end cell is also a variable quantity. In fact it is quite evident that certain external factors (climatic and edaphic as well as physiographic) play no small part in determining the form and struc- ture of the lamellae, the leaves, and even the whole plant. The query sug- gests itself, “Are these factors alone wholly responsible for the existence of any of the varieties which have received distinctive names?” Here is a good field for experimentation.

Polytrichum formosum was reported from various New England states prior to 1885. Undoubtedly the bulk of the material so reported must be referred to P. Ohioense as has been repeatedly shown in various articles and catalogues since the date mentioned.

Polytrichum gracile was reported from Massachusetts and New Hamp- shire in 1847 by William Oakes (Hovey’s Magazine, 13: 174). Dr. A. J. Grout writes me that the only specimens of this species which he has were collected in Vermont, so the New Hampshire locality mentioned in Rhodora (1: 53) is undoubtedly an error. The Vermont plants were collected on both Willoughby Mt., and on Mt. Mansfield by Dr: G. G. Kennedy.

Polytrichum Jensenii is a plant which is known from Lapland, Finland, Spitzbergen, Greenland, Alaska, and the Yellowstone Park. The Maine plant which is here referred to this species grew amongst sphagnum in a bog at Presque Isle. It differs mainly from authentic material, kindly loaned by Mr. J. M. Holzinger, in having longer and somewhat flexuous stems, less rigid leaves, and thinner-walled marginal cells of lamellae.

DIE EUROPAEISCHEN TORFMOOSE.

By G. Roth, Verlag von Wilhelm Engelman, Leipzig.

Herr G. Roth, whose exhaustive work on the European mosses was ably reviewed by Prof. Holzinger in the pages of The Bryologist last year (Vol. viii, p. 1 13), has placed students of bryology under further obligations by the publication of his work on the European Sphagnaceae. This work consists of eighty pages of letter press with eight plates, uniform in size and method of reproduction with his “ Euro paeisc he Lciubmoose,” and it is published at the very moderate price of 3.20 marks.

After an introduction, giving a concise account of the intimate structure of these remarkable plants, Herr Roth, in the systematic portion of his work, follows very largely the lines taken by Dr. C. Warnstorf, familiar to many English students, in Mr. S. C. Horrell’s “ European Sphagnaceae P and lately further amplified by Dr. Warnstorf himself, in his “ Leber und Torf moose der Mark Brandenburg .”

103 —

The researches of M. Meylan, in the Jura, on the Sphagna of the acuti- folium group (Rev. Bry., 1906, p. 17, etseq. ) have, I think, thrown some doubt on the permanent validity of some of the species recently put for- ward in this group. Herr Roth, however, is fully aware of the unsatisfac- tory character of some of the species, since he draws attention to the fact that most of the species are connected by intermediate forms. Whatever view may ultimately be adopted in reference to the species within this group, students will be grateful to Herr Roth for bringing together and collating the views of various authors on the modern lines, where collation presents more than usual difficulty.

The plates give the general facies of the plant, with details of the leaves, cells and pore structure and add very materially to the usefulness of the work. A Key is given to the species of the cymbifolium group, but this sys- tem is not extended to the other groups, which, indeed, for the most part, do not readily lend themselves to this method of treatment. The descriptions of the species are carefully done and the whole distribution of the species is given, so far as it is known to the author, and, as in most cases, the species are common to Europe and Norch America, the book will be found useful by students on both sides of the Atlantic. Four new species are added to the list of the European Sphagna, bringing the total number up to fifty-three.

The new species are: S. Schliephackei (Roll), S. pseudorecurvum (Roll)

and S. pseudocuspidatum Roth, of the cuspidatum group, and S. pungens Roth, of the subsecundum group. Moreover, S. rufescens Bry. Germ, is split up into two species: 5. rufescens Bry. Germ, and S. cornutum, Roth; the latter characterized by numerous ringed commissural pores, like strings of pearls, both on the inner and outer surfaces of the leaves.

Purists in the matter of language will be glad to find that the somewhat mongrel name, “ crassicladumf has given way to the older name turgi- dum C. ,M., while many will be pleased to find that the familiar S. laricinum Spruce, has been re-instated.

In conclusion the author explains a simple method of staining by the use of Methyl violet, which acts very rapidly and enables the more intimate structure and position of the spores to be readily observed.

MEETING OF THE SULLIVANT MOSS CHAPTER.

The meeting of the Sullivant Moss Chapter, already announced in the May Bryologist, will take place at the New York Botanical Garden, Bronx Park, New York City, on Saturday, Dec. 29th, at 2 p. m. It is not possible at this writing to specify the room in which the meeting will be held.

A most gratifying response has been received to the circular letter of June 22d, and a program of much interest is assured, consisting of informal papers, discussions, and the exhibition of material. Those members who will contribute are requested to send notice to the President before Dec. 1st in order that an outline program may be sent to the Chapter by the end of the first week in the month. If those members who will attend the meet- ing, and all who can are urged to do so, will inform the President or the Treasurer of their intentions at the earliest date possible, it will be greatly appreciated. Edward B. Chamberlain,

President.

Parts III and IV of “Common and Conspicuous Lichens of New Eng- land,” by Reginald Heber Howe, Jr. and Marion Appleton Howe, have been received. Parts I and II were reviewed in the Bryologist for May by Prof. Bruce Fink. In it he calls attention to the fact that the half tones are not quite all that could be desired and it is a pleasure to notice a great improve- ment in them, especially in the last part issued. A. M. S.

The attention of all field workers is called to the article on Polytrichum commune by Prof. J. Franklin Collins in this issue, and especially to the desire of the author for material from all sections of the country.

We welcome two new members this month, Mrs. H. E. Young, Atlin, British Columbia, Canada, and Prof. Wm. P. Holt, 1004 Jefferson Avenue, Toledo, Ohio. This makes our membership 177.

NOTICE— ELECTION OF OFFICERS FOR 1907.

The members of the Sullivant Moss Chapter are requested to forward ballots at once to the Judge of Elections, Prof. J. Franklin Collins, 468 Hope street, Providence, R. I. Polls close November 30th. The following candidates have signified their willingness to serve, if elected. Members, however, are at liberty to vote for any other candidates, should they prefer to do so.

For President— Mr. Edward B. Chamberlain, 519 West 121st street, New York City.

WILLIAM MITTEN.

A Sketch with Bibliography.

William Edward Nicholson.

The bryological world is the poorer to-day by the loss of the veteran bry- ologist, William Mitten. Born at Hurstpierpoint, in the County of Sussex, the 30th November, 1819, he was in his 87th year when he passed away on the 20th July last.

By profession a pharmaceutical chemist, he was in early life apprenticed at Lewes in the same county to a chemist of the name of Saxby, who carried on business at a shop which has long since disappeared. He soon evinced a strong taste for various [branches of natural history, and a story is still current in the town that, somewhat to his master’s annoyance, those numer- ous pigeon holes, so general in a chemist’s [shop, with the mysterious labels Rh. Zingit, etc., etc , were frequently found to harbor “specimens” by no means corresponding to the label outside.

A fortunate acquaintance in early life with William Borrer, a well- known Sussex botanist, and Sir William Hooker caused him to turn his attention to the study of mosses and hepatics, and as early as May, 1843, he recorded the discovery from near Erith of Aulacomnium androgynum Schwgr, in fruit, a very rare condition in Europe, while in 1846 he discovered near Hurstpierpoint the rare and interesting Weisia (Astomum) Mitte7iii which was named after him, and soon afterwards described by the authors of the Bryologia Europea, then in course of publication. Shortly after this Mitten turned his attention to the study of exotic mosses and hepatics, and in 1851 he published, in Hooker’s Journal of Botany, “ a Catalogue of crypto- gamic plants, collected by W. Jameson in the vicinity of Quito.” From this time, until a few years before his death, his work on exotic bryology was continuous, as will be seen from the subjoined list of his principal publica- tions, and during this period most of the collections of mosses and hepatics received at Kew passed through his hands for determination. I regret my inability to discuss Mitten’s work on exotic bryology, as I have not had the leisure or opportunity for studying mosses over a wide field. A general review of his work by a more competent pen would be most useful.

Mitten was on the side of the “ splitters r rather than of the “ lumpers,” but in dealing with a group where there was so much new ground to be cov- ered, such an attitude is in many ways justifiable, and it may reasonably be left to a later generation to take a more synthetic view. In any event, Mitten was fully aware that much yet remained to be done in this direction. Shortly before his death he told me that he had been looking through his North American Brachythecia with, I believe, a view to their revision though I am not aware that this group particularly needs reduction or that Mitten’s project took any definite shape.

The November Bryologist was issued November 1, 1906.

The demands of his business and the res angusta aomi rarely allowed Mitten to leave his home, and in these days of constant traveling it is strange to read of one who, as Mr. W. B. Hemsley informs us, told Sir William Hooker in 1854, had only been away from home for two week-days for five years. When his daughter Flora, in later years, relieved him of some of his business, he had more leisure, and on one occasion he made a visit to Switz- erland, of which he cherished very pleasant recollections, and in the course of which he gathered many things previously only known to him in herbar- ium specimens. He told me of the particular interest which he had found in visiting the district, in which Schleicher had botanized.

It was not until late in the autumn of his long life that I had the privilege of a personal acquaintance with Mitten. My first letters from him, dated in the early part of the year 1895, are in reference to Pottia caespitosa and other rare Sussex mosses which he most kindly directed me to find. His letters are models of that painstaking accuracy which, I believe, characterized his work generally, and they were also full of encouragement to me, who was little more than a beginner at the time, as he concluded his first letter with the remark: “ I shall always be glad to hear of any new or strange moss you may meet with, and hope you may find as. much to interest you in mosses as I have for so many years.” The implied promise of assistance was amply redeemed in our subsequent correspondence.

My opportunities of seeing Mitten were few and far bet ween, *but it was always a pleasure to look in and see him in his quiet home, surrounded by his garden in which he took so much interest, and which harbored many rare and curious plants. On the last occasion on which I saw him he was regret- ting the wild luxuriance of several rare British plants which had spread beyond all bounds and which, as he observed, wanted all the place to them- selves. On another occasion, in 1903, I had the pleasure of showing him fresh specimens of Weisia Mittenii, which I had recently found and in which he was much interested, as it had not, I believe, been gathered since his ori- ginal discovery of it in 1846.

Mitten was an associate of the Linnean Society of London, to which he was elected in 1847, an honorary member of the Linnean Society of New South Wales, and of the New Zealand Institute, and also of the Brighton Natural History Society, and the South' Eastern Union of Scientific Societies.

Mittenia Gottsche was a genus of hepaticae allied to Pallavicinia (Ann. Sci. Nat. Ser. 5, I. 1862), and Lindberg in 1863 put forward the genus Mit- tenia of mosses as a substitute for Mniopsis already in use.

There is an excellent portrait of Mitten in the October number of the Journal of Botany, accompanying an interesting notice of him by Mr. W. Botting Hemsley, from which I have borrowed a few details. I am also indebted to his daughter, Miss Flora Mitten, for assistance in compiling these notes, and to Mr. A. Gepp, of the British Museum, for a greater part of the subjoined list of Mittens’ publications, mostly taken from the Royal Society’s catalogue. Mitten leaves a widow who is 93 years of age, three unmarried daughters, and a fourth who is the wife of the famous naturalist

Selection.

NOTES ON VERMONT BRYOPHYTES-1906.

By A. J. Grout.

Although the flowering plants and ferns of Mt. Mansfield have been care- fully studied and listed, the bryophyte flora has received less attention. Mr. C. G. Pringle, who first explored this region with thoroughness, collected many mosses and hepatics, but it was his custom to collect only fruiting plants. Mrs. Britton, Dr. Evans, Dr. Kennedy and myself, have done some collect- ing of bryophytes on the mountain and in its vicinity.

This season it was my pleasure to attend the meeting of the Vermont Botanical Club on the mountain and to spend a week on the summit, engaged chiefly in collecting mosses.

Dr. Kennedy had previously reported Tayloria tenuis , but I came upon such quantities of it as to be able to supply Prof. Holzinger with enough for his Musci Acrocarpi Bor. -Am. and have an abundant supply left. It grew along the banks of a little rivulet into which the Summit House sewer dis- charges, but far enough down so that it was not offensive. Schistostega is abundant in the deep clefts in overhanging rocks on the northeast side of the mountain, below a point in the road about a quarter of a mile from the hotel; I also found it in a crevice about ten feet to the left of the cave in the north face of the “Nose.” These high, damp, creviced north-facing cliffs of the “ Nose,” near the hotel, are an ideal collecting place for rare and interesting mosses. Here Swartzia ?nontana is very fine and abundant and fruits freely; in damp crevices in overhanging rocks is an abundance of Amfthid- ium Lapponicum. In the deepest, darkest, and dampest clefts was a limited supply of Rhabdoweisia denticulata and Cynodontium gracilescens. On the wet soil at the base of overhanging cliffs is a variety of Plagiothecuim den- ticulatum near var. obtusifolium; with this and in similar places was an abundance of Pohlia cruda , mostly sterile. In spots similar to those men- tioned last is an Amblystegium which I made A. vacillans. On these cliffs Andre aea petrophila is abundant and fruits freely. While abundant on rocks all about the summit, it seems not to fruit to any great extent on the more exposed portions of the mountain.

I thought I had some knowledge of Pohlia nutans , but here I found it so variable that I collected it a dozen times, thinking each time that I had some- thing different from the previous collections. If any one with the species- making instinct, like that which has recently dealt with Thorn Apples and Violets, ever takes hold of Pohlia nutans , I tremble for the result. There were large robust forms and small slender forms, forms with small capsules and forms with large capsules, forms with seta long and slender and others with seta short, forms with leaves typical and others with lower leaves shortly oblong-ovate and rather short acuminate. One form common on the summit in wet places, such as the edge of rain pools, resembles the form described by Mr. Dixon in his notes under this species. This fruits rather sparingly, but certainly is paroicous. Sterile specimens have been issued by Prof. Holzinger in his Musci Acrocarpi Bor. -Am. as Weber a commutata.

Hypnum stramineum is abundant in bogs on and near the summit of the mountain, and associated with it, in the bog back of the house, I found Dicranum Bonjeani,ysrh.ioh is also distributed in Prof. Holzinger’s sets. Plagiothecium e leg ans grew nearly out of reach in the “ Snow Cave.” near the “Lips.” Bryum pseudotriquetrum was collected by Mr. Stewart H. Burnham beside the road near the summit.

Species New to the State from Other Localities.

Andreaea Rothii W. & M. Jamaica, Frank Dobbin, com. S. H. Burnham.

M?iium cinclidioides (Blytt.) Hueben. In a slow mountain brook with Fontinalis, Newfane.

Philonotis Muhlenbergii (Schwaegr.) Brid. Brookline. There is also a specimen of this moss in the collections of Columbia University from Jones- ville. The perigonial leaves of this species are erect, lanceolate and acute, with the costa percurrent in the inner leaves. In P. fontana the perigonial leaves are spreading, broadly triangular-ovate, the inner often obtuse and rounded at apex,

Pohlia proligera (Lindb.) Correns. On Newfane Hill, fruiting.

Amblystegiuin vacillans Sulliv. and Plagiothecium elegans (Hook.) Schimp., mentioned above, are also new to the state. A species of Ditrichum , believed by Dr. Best and myself to be new, was collected in good condition and in considerable quanity on Newfane Hill.

Additional Localities for Rare or Interesting Species.

Anacamptodon splachnoides. Knothole in apple tree, Newfane.

Barbula convoluta on old brick, Newfane. On limekiln waste, Strat- ton.

Pohlia cruda is abundant in cool, moist ravines and crevices of cool, shaded cliffs in Newfane, and probable throughout the state. It fruits infre- quently, but may be distinguished from the other species of the genus by the very long and narrow areolation.

Rhabdoweisia denticulata. North-facing cliffs, Newfane Hill. Of the specimens from this locality Dr. Best says: “The Rhabdoweisia has the

leaves of fugax but the peristome is that of denticulata. It is probably Boulay’s R. fugax sub denticulata which Limpricht refers to denticulata. My own opinion is that both are forms of one and the same specific type and represent the extremes of a series, and yours is an intermediate form.”

Parts 224 and 226 of Engler & Prantl Pflanzenfamilien were received in May and October, 1906. They include the following orders : Spiridentacece ,

Lepyrodontacece, Pleurophascacece , Neckeracece and Lembophyllacece ; including twenty-three genera having species in North America of which the following are found within the limits of the United States:

Pirea Card. Bull. Soc. bot. Belg. 32: 175. 1893.

— 8—

The type species of this genus are from Central America, but Brotherus adds two West Indian species and transfers to it Neckera cymbifolia and N. Luddoviciae of the manual, removing them from the Meteoriae to the Pter- obryeae. As the distinctions between these two tribes are based on the peri- stome and neither of these species has been found in fruit, their true affinity still remains somewhat problematical. They have previously been referred to Pilotrichella (C. M.) Besch. which includes thirteen species from the West Indies and Central America.

Papillaria C. M. includes thirteen species from the West Indies and Cen- tral America with P. nigrescens (Sw.) Jaeg. from Florida and Louisiana extending into Mexico, Costa Rica, Jamaica and the Antilles.

Meteorium { Brid.) Mitt. Journ. Linn. Soc. 12: 427, 1869.

Pilotrichum Sect. Meteorium Brid. Bryol. univ. 2: 264. 1827.

The citations for this genus, as given by Brotherus, are puzzling and misleading. Bridel originally included under this section two species from Nepal, India, of which one is transferred to Papillaria (P. fuscescens) leaving P. filamentosum as the type of Meteorium.

This species is not retained in the genus either by Fleischer or Brotherus, but placed in Aerobryidium Fleischer, a new genus. Four species from Mex- ico and the West Indies are retained in Meteorium. Meteorium pendulum Sull. is transferred to the following genus: — Floribundaria C. M. Linnaea 40: 267. 1876. One North American species, P. pendula (Sull.) Fleisch. is distributed in Louisiana, Japan, China, Formosa and Java.

Neckera Hedw. Fund. 2: 93. 1782, is maintained with twenty-six North American species.

Under Thamniece Brotherus recognizes five genera of which four include North American species. He continues to use the generic name of Tha?n- nium Br. & Sch. (1852) in spite of its being antedated by three homonymns dating back to 1799, 1825' and 1838. Porotrichum (Brid.) Dozy & Moelk. is also maintained, and the two genera are separated on the character of the teeth, whether transversely striate above or below. Nine Central American and West Indian species are listed under Porotrichum and seven under Thamnium , with two from the United States under the latter genus Th. A lleghaniense and Th. Leibergii.

Bestia Brotherus in Engler & Prangl Pflanzenfamilien 226, 858. 1906, is dedicated to Dr. George N. Best. This a new generic name the synonymy of which is as follows: —

Alsia longipes Sull. & Lesq.

Dendroalsia longipes E. G. Britt. Bull. Torr. Bot. Club 32:265, 1905.

This is a rare and beautiful California species, and Dr. Best is to be con- gratulated on having his name associated with it.

New York Botanical Garden.

Mr. Herman S. Simmons, Lund, Sweden, desires to sell his Moss Herb- arium. It contains collections made by various Scandinarian bryologists : Lindberg, Kaurin, Hagen, Jensen, and others. For information as to price, etc., address Mr. Simmons as above.

“The three species just quoted together with L. gracilis (Schleich.) Steph.

Floerkii as a variety of L. lycopodioides^ .an opinion which has the sanction of Lindberg. With a little

care it is not difficult to distinguish these five species, and, with the exception of L. Floerkii and'Z. lycopodioides , they show no tendency to vary into one another. L. gracilis is not uncommon in mountainous regions and is the smallest species of the group. It may usually be recognized at a glance by its upright flagelliform branches which bear gemmae near the apex and closely appressed leaves in the lower part. These branches, which are simi- lar in appearance to the gemmiparous branches of Odontoschisma denudation and Kantia Trichomanis are sometimes very abundant, covering over an entire tuft of the plant, but sometimes they are very sparingly produced.

Of the other four species L. barbata and L. Lyoni agree with each other in having inconspicuous or obsolete underleaves and in lacking mar- ginal appendages of any sort near the postical bases of the leaves, while L. Floerkii and L. lycopodioides agree in having large and conspicuous bifid underleaves and in developing clusters of slender branched cilia near the pos- tical leaf-bases. L. barbata is rather more robust than L. Lyoni , but the most reliable differential characters are drawn from the leaves. In L. bar- bata these have their antical and postical margins of about the same length and approximately parallel, while the teeth at the truncate apex are three or four in nnmber, subequal in size and obtusely or subacutely pointed. If we should pass a straight line through these teeth, it would lie parallel or nearly so with the axis of the stem. In the leaves of L. Lyoni the postical margin is strongly curved and is much longer than the antical, the sharply pointed teeth are commonly three in number and the postical tooth is considerably larger (than the others. If we should pass a straight line through these teeth, it would form an acute angle with the axis. Lophozia Lyoni is commonly known as L. quinquedentata, but there is so much doubt as to what the ori- ginal Jungerniannia quinquedentata really was that it seems best to discard the name altogether, as both Pearson and Stephani have recently done, and to take up the later name of Taylor, about which their is no doubt whatever.

The differences between L. lycopodioides and L. Lloerkii are those of degree rather than kind. L. lycopodioides is the more robust of the two, its leaves are larger and more crispate, the teeth are often mucronate instead of being bluntly pointed, the basal cilia are more abundant and more finely divided and the divisions of the underleaves are more conspicuously ciliate. Typical specimens can be distinguished from each other at a glance, but one occasionally meets with forms which are difficult to refer definitely to either species and which apparently represent intermediate forms. As has already been noted both species are almost universally recognized in spite of this fact.” Evans, Rhodora 4: 210, 211, 1902.

IS PHYSCOMITRIUM IMMERSUM A GREGARIOUS MOSS?

John M. Holzinger.

This pygmy in the genus to which it is referred, according to Mrs. E. G. Britton’s account in her Revision of the Genus Physcomitrium in Bull. Tor. Club, Vol. 21, No. 5, May 25, 1894, has an extensive range from New York to Kansas, from Colorado to Quebec. I have had it under observation near Winona, Minn., for over twelve years, looking up its haunts annually. In all these years I have never succeeded in finding more than a few plants in a tuft, the little plants seemingly preferring to stand alone, isolated , among the hepatics which seek the same moist substratum. The three hepatics, among which I uniformily find it, were recently determined for me by Dr. A. W. Evans as Ricciocarpus natans (L.) Corda, Riccia fluitans L., both terrestrial forms, and Anthoceros Macounii M. A. Howe, which last determ- ination Dr. Evans had verified by Dr. Howe himself. Incidentally, Dr. Evans points out, this extends the range of Anthoceros Macounii into the United States, its type station being in Canada, One or the other of these terrestrial hepatics, and in some cases even all of them, may be found asso- ciated with P hyscomitriu7n immersum sent out by me, and indeed the nature of its recurrence here compels me to include an excess pf these hepatics with a relatively scant amount of the Physcomitrium, Another plant that will frequently be found in the pockets is Ephemerum crassinervium with its great abundance of protonema. P hy scomitrium immersum will be distributed in fascicle ten of my Musci Acrocarpi, now in process of preparation.

SULLIVANT MOSS CHAPTER ANNUAL REPORTS REPORT OF THE PRESIDENT.

The past year has been one of great prosperity for the Sullivant Moss Chapter: a gain of thirteen per cent, has been made in the membership ; the intensive study of local floras has increased: especial interest has been mani- fested in the study of the lichens and hepatics, as is shown by the increased space devoted to them in the last volume of the Bryologist: and the vari- ous herbaria belonging to the Chapter are fast becoming of consulting value to students of the distribution of North American Plants.

At the founding of the Chapter, one purpose was to bring the various isolated moss students throughout the country into closer touch with one another. As evidence of the success of this plan, it is only necessary to con- sider the contributions which are constantly being made by Chapter mem-

t

—14—

bers to the exsiccatae issued by Dr. Grout and Prof. Holzinger. In addition to this, however, it is increasingly evident from the letters of individual members, that a spirit of service is rapidly developing which augurs well for the future prosperity of the Chapter.

The character of the offerings made in each issue of the Bryologist also deserves notice. During the past year there has been a gratifying increase in the number of rarer species offered. Every effort should be made to develope this department, not only for the value of the exchanges, but also because familiarity with. the appearance of rarer species undoubtedly leads to their detection in new localities. Members are urged when making offer- ings to be especially careful to specify the locality in which the specimens were collected. This practice enables those desiring specimens to chose offerings with greater ease, and prevent the receipt of the same species from localities already well represented in the applicant’s herbarium. The same species, moreover, often varies greatly in exchange value and in appear- ance, according to whether it comes from the .center of its known range or from a point near the limit. It is but courteous, therefore, that those mak- ing the offerings give some indication of the origin of the specimens.

In my last report I mentioned the value of local flora work. While it is perhaps too soon to attempt any correlation of the distribution of mosses, lichens, or hepatics, with the underlying geological formation, yet the vari- ous local lists which have recently been published in the Bryologist, or notes such as that of Prof. Holzinger upon Grimmia glauca , with its men- tion of the remarkable features of the driftless area in Minnesota, lay found- ations upon which future workers will build.

Finally, I wish to extend my sincere thanks to the members for their ready response to the circular letter sent out in June, and for their willing co-operation in making the third meeting of the Chapter a success.

Respectfully submitted,

Edward B. Chamberlain,

President.

REPORT OF THE SECRETARY.

During the past year the Chapter has added twenty-three to its member- ship, ten have withdrawn, four died, giving a total of one hundred and sixty- five as listed in this number of the Bryologist.

The herbarium has been increased by a large number of interesting additions. The Rev. Mr. Watts, of Young, South Australia, has sent us a large collection of mosses from his locality. Mr. Nickolson, of England, has sent us specimens from England and the Continent. Mr. Haydock sends many from the White Mountains: Mr. Foster a lot from Wallowa, Oregon, with notes on the geological formation. Dr. Grout, Rev. Dupret, Cannon Lett of Ireland, Prof. Bonser of Spokane, Dr. Breckle of North Dakota, Miss Miller of Washington, D. C., and many others are contributors.

Thro the courtesy of Prof. Frye, of the University of Washington, many of our Pacific slope mosses have been obtained.

— 15 —

The southwestern portions of the United States and the Rock}7- Moun_ tain regions, both north and south, are but poorly represented.

The herbarium is in good condition, but in order that it may remain so some provision should be made for the future. It should be kept in a tight wooden or tin lined box, possibly two boxes. In its present quarters, a large dry-goods box, it is open to the attacks of mice and insects. The herbarium is rapidly increasing in value and should be insured. This costs but little, and in case of fire, altho we all appreciate that no money can altogether replace a collection of this kind, the Secretary’s mind would thereby be relieved.

The matter of offerings cannot be too strongly urged upon Chapter mem- bers; there is no locality that does not present something of interest to some other member. Generally about twenty-five specimens are sufficient for an offering, and from one to three species are enough at a time.

The Secretary wishes to thank the officers fcJr their help and suggestions during the year, and wishes here to call attention to the work of his prede- cessor, Miss Miller, who was evidently a worker and had the Chapter affairs so systematized that the present incumbent has had little to do but to fol- low in her footsteps.

Attention should be called to the fact that the herbarium is always at the disposal of Chapter members and they can obtain loans .of specimens at any time. Respectfully.

Seattle, Wash. John W. Bailey.

REPORT OF THE HEPATIC DEPARTMENT.

It is certainly gratifying to note the lively interest taken in this depart- ment. In response to my request several have sent in collections from vari- ous states. The largest sets have come from the following: Mr. E. B.

Chamberlain, from Maine and Rhode Island; Mr A. S. Foster, from Wash- ington and Oregon; Dr. J. W. Bailey, from Washington; Mrs. E. B. Taylor, from Georgia and Florida; Miss M. F. Miller, from the Catskill Mts., New York: Mr. J. L. Sheldon, from West Virginia; Dr. A. J. Grout, from various localities. These, with many smaller collections, are substantial evidence of the efforts to make our Chapter Herbarium of practical value. By exchange we have acquired the following sets: Messieurs Grape and Arnell, thirty-

six herbarium specimens from Sweden and Norway, capable of being divided into more than double that number, and these duplicates will bring in new sets. Messieurs Potier de la Verde and Charles Lacouture, sixteen and twenty-four herbarium specimens from France also capable of division. Mr. E. B. Chamberlain has given nineteen specimens from l’Herbier Boissier. Dr. Bailey’s material from Washington has been devoted to offer- ings, by request, reserving a set for the herbarium. Sufficient material for eight hundred and thirty pockets was sent in this year, representing three hundred and thirty-one herbarium specimens, the remainder being dupli- cates. Again we acknowledge with pleasure our indebtedness to Dr. Alex- ander W. Evans for determinations and verifications of troublsome species. It is hoped that members will continue their generosity, and that their exam- ple will be a stimulus to others to collect and to study these charming forms. I shall be glad to give small sets to facilitate the work of those taking up the study of hepatics. Respectfully submitted,

Caroline Coventry Haynes.

REPORT OF THE LICHEN DEPARTMENT.

Interest in the lichens is unabated and many of the students have car- ried their explorations after specimens to a point beyond that of cursory examination. The more than three thousand specimens submitted for iden- tification or verification during the past year have committed this depart- ment to considerable labor, but the time and effort have been cheerfully given; That portion of the Chapter Lichen Herbarium accumulated prior to Jan. i, 1803, is in our charge. Accessions to the collection, except for an individal contribution of one hundred specimens, have been limited to three (3) numbers. It is to be regretted that voluntary gifts to the herbarium are not more numerous, but this does not diminish our thanks to those who have remembered. Respectfully,

G. K. Merriel.

FURTHER NOTES ON CLADONIAS. IX.

Cladosm squamosa and Giadonia subsquamosa.

Bruce Fink.

As promised in the last paper of this series (Bry. 9; Nov., 1906) the species to be considered next in order is Cladonia squamosa. A somewhat close relationship seems to exist between this species and two of those con- sidered in the last paper, viz Clado.nia caespiticia and Cladonia delicata . When we consider the differences that appear in the horizontal thalli of the three species, we can hardly think that we have a possible immediate gen- etic line in these species, but the relation is close enough to cause frequent confusion on the part of persons reasonably well acquainted with lichens. If the considerations below and preceding, with the accompanying figures, aid in alleviating the difficulties encountered in the study of these plants, the writer will have accomplished his purpose.

The close relationship between Cladonia squamosa and Cladonia sub- squamosa is generally admitted by lichenists, and the two species are there- fore considered in succession in the present paper.

There is still one other difficulty that will be met in the study of Cla- donia squamosa, and that is confusing certain forms of this species with forms of Cladonia furcata. The squamules, both of the primary thallus and the podetia, should furnish sufficient means for differentiation, to say nothing of the podetia, and yet the separation is not always easy to make. As good cladoniologists as Dr. Wainio and L. Scnba failed to agree on a form of Cladonia furcata collected by the writer at Fayette, Iowa. Mr. Scriba thinking it might be a form of C. squamosa rather than C.furcatay but surely all one species, and Dr. Wainio thinking from the material exam- ined that both species were represented in the material sent. Repeated' studies at the spot where the plant grows fully convinced the writer that all belonged to the one species. C. furcata. A considerable portion of this, material is still in the writer's herbarium, and specimens will be sent to any persons sufficiently interested to send for them.

On soil, especially humus, or on rocks partly covered with soil, rarely on rotting wood. Grows best in shaded moist places. Examined by the writer from New Bedford, Mass. (H. Willey, who determined as C. delicata ), Washington (W. W. Calkins, who determined as C. decor ticata), Newfound- land (A. C. Waghorne), White Mountains (W. G. Farlow), New York (E. A. Burt and Carolyn W. Harris), Ohio (E. E. Bogue), North Carolina (H. A. Green), New Hampshire (Clara E. Cummings and G. K. Merrill), Maine (col- lector unknown), Missouri (Colton Russell), Nebraska (T. A. Williams), Iowa,- Minnesota, Illinois, Ohio, Puget Sound, Alberta and British Columbia (Bruce Fink), Ontario (A.. C. Waghorne), Alaska (Wm. Trelease). Listed from Florida by Eckfeldt and Calkins, and Wainio adds Greenland, Vancouver Island, Alabama, and Louisiana. For further wide distribution in British America see John Macoun’s “Catalogue of Canadian Plants,” part VII. The above gives a general North American distribution, and the plant is also known in all the grand divisions.

The plants listed above, so far seen by the writer, seem to be var. denti- collis (Hoffm.) Flk., which is common in Europe and America and must stand for the species.

Cladonia squamosa muricella (Del.) Wainio Mon. Clad. Univ. 1: 431. 1887. Podetia cupless, commonly almost completely decorticate, sometimes sparsely sorediate, more or less squamulose.

Podetia arising from the surface of the squamules, 12-35 mm. long in ours and becoming twice as long in foreign plants; subcylindrical or tubaeform: sometimes cup-bearing; irregularly branched or rarely simple; axils sometimes perforate: the apices cup-bearing,

obtuse and perforate or rarely subulate; erect, the cortex verrucose or areolate or almost wholly decorticate; sometimes squamulose towards the base and squamulose-scaly higher up; whitish-sea- green or varying toward brownish: the base sometimes dying and becoming dark colored. Cups when present perforate, and the margin becoming repeatedly prolifer- ate. Apothecia commonly small, o. 5-0.7 mm. in diameter; subsolitary or more or less aggregated at the apices of the branches; flat and thinly mar- gined or becoming convex and immarginate, brown. Hypothecium pale. Hymenium pale below and brownish above. Paraphyses with thickened apices. Asci clavate. Specimens seen sterile and apothecial characters taken wholly from Dr. Wainio.

A single collection from the same locality as the last variety was placed here by Dr. Wainio. The specimen was collected on earth over rocks. Previously known in North America only from Vancouver Island and Alaska. A rare plant, Dr. Wainio citing a single locality from each of the following grand divisions, — Europe, South America and Australia.

In closing this paper, a word is in order regarding the photographs for illustration. These have been furnished thus far, in part, by Mr. C. J. Hibbard, Dr. E, T. Harper and Mr. G. K. Merrill, and in part by the Bryologist, The writer spent a summer with Mr. Hibbard photographing lichqns, and it was through this connection that Mr, Hibbard was called upon to illustrate the first paper. Since then, Mr. Merrill has furnished the photo- graphs for four papers, Dr, Harper for one and the Bryologist for the other two. During the session of the University of W ashington Marine Station, for the summer of 1906, the writer was with Dr. Harper, who was doing a large amount of photographing of lichens and fungi, and gained his consent to illustrate the remainder of the papers of this series. So we are under obliga- tion's to Dr. Harper until the series is finished.

Our illustration of Cladonia squamosa is from a specimen sent by L. Scriba of his own collecting in Germany, and named by him Cladonia squamosa var. denticollis, form squamosissima Flk. , while that of the var. phyllocoma is from the specimen collected by the writer at Emo, and deter- mined by Dr. Wainio.

THE GENUS CALYP0GE1A AND ITS TYPE SPECIES.

By Alexander W. Evans.

Dr. Emilio Levier, of Florence, a careful student of the Hepaticae, has recently given excellent reasons why the generic names Kantia and Cincin- nulus should be set aside in favor of Calypogeia A Since Kantia has been accepted in North America for several years, a discussion of these reasons may perhaps be of interest to American botanists.

The genus Calypogeia of Raddi was published in 1818.1 2 3 In its original form it was composed of two divisions or sections, the first, A (examphigas- triatae), for species without underleaves, the second, B (amphigastriatae), for species with underleaves. In the section -A, Raddi placed two species, C. ericetorum and C. flagellifera, the first proposed as new, the second based on one of Micheli’s prelinnaean species. In the section B, he placed a single species, C. fissa (with the variety integrifolia ), but quoted under this species, as synonyms, the following: Mnium fissum L., Jungermannia sphaero-

cephala With., Jungermannia Trichomanis Dicks., a prelinnaean species of Dillen, a species of Micheli, also prelinnaean, and Jungermamiia calypogea Raddi, the last-named species having been published ten years previously. 3

The Jungermannia Trichomanis which is here given as a synonym was based on Mnium Trichomanis L. At the time Raddi wrote, M , Trichomanis and M. fissum were not considered distinct from each other, and both may be found quoted as synonyms of Jungermannia Trichomanis in Hooker’s British Jungermanniae, published in 1816. There is nothing surprising, therefore, in the fact that Raddi made no attempt to keep them apart.

Three years after the appearance of Calypogeia , S. F. Gray proposed the genus Kantia (or Kantius ), with the single species K. Trichomanis . 4 Under this species, following the example of Hooker, he gave both Mnium Trichomanis and M. fissum as synonyms. The following year the genus Cin- cinnulus of Dumortier was published,5 6 also with a single species, C. Tricho- manis , which was the precise equivalent of Kan'tia Trichomanis S. F. Gray. Both Gray and Dumortier were at that time ignorant of the earlier work of Raddi, and Dumortier was also ignorant of the work of Gray.

In 1829 Corda recognized the genus Calypogeia and proposed the name C. Trichomanis . 6 He based his species on Jungermania Trichomanis Dicks, and, like his predecessors, included under this species 'both Mnium Trichomanis and M. fissum. Why he chose Trichomanis as the specific name and discarded fissa , which Raddi had already chosen, is not stated. Perhaps it is because M. Trichomanis precedes M. fissum in the Species Plantarum of Linnaeus, where these names first appear.

In 1836 Nees von Esenbeck also accepted the genus Calypogeia but saw

the necessity for dividing it into two genera corresponding to Raddi’s sec- tions, A and B. He proposed the generic name Gongylanthus for section A, and reserved the name Calypogeia for section B. 1 In the Synopsis Hepaticarum the two genera are understood in this same sense, and they continued to be so understood for nearly thirty years.

Early in the seventies Lindberg revived the generic name Kantia and applied it to the genus Calypogeia as restricted by Nees von Esenbeck. At the same time he discarded the name Gongy lanthus and restored to this genus the name Calypogeia ,2 In other words, while recognizing the two genera into which Nees von Esenbeck had divided the original genus, he reserved the name Calypogeia for Raddi’s section A, and applied to the section B the next oldest available name Kantia .

Since this time there has been considerable diversity in the usage of the names. Some botanists have followed Nees von Esenbeck: others have fol- lowed Lindberg; still others, while accepting Calypogeia in Lindberg’s sense, have repudiated the name Kantia in favor of the later name Cincin- nulus. The course to be adopted naturally depends upon which of Raddi’s three original species ought to be considered the type of the genus.

From the fact that Raddi quotes Jungermannia calypogea as a syno- nym of Calypogeia fissa, Levier draws the conclusion that C. fissa is the species which furnished to the new genus not only its characters but even its name, and that it constituted the primordial type of Calypogeia ten years before the other two species, C. ericetorum and C. flagellifera , were estab- lished. On this basis he asserts that it would not be justifiable to emend or restrict the genus in such a way that C. fissa should be excluded. Of course it was precisely this result which was brought about by Lindberg when he reserved the name Calypogeia fjpr Raddi’s section A.

Levier’s position is fully supported by the International Rules of Nomen- clature adopted at Vienna by the recent Botanical Congress. Unfortunately these rules do not discuss directly the important subject of generic types, but Article 45 provides fully for the present case. The first two sentences of this article are as follows: When a genus is divided into two or more genera, the

name must be kept and given to one of the principal divisions. If the genus contains a section or some other division which, judging by its name or its species, is the type or the origin of the group, the name is reserved for that part of it. Applying these rules to Raddi’s genus it is clear that the emended Calypogeia must be reserved for section B, because this section contains the species Jungermannia calypogea , even though this species be treated as a synonym.

The Code of Botanical Nomenclature which was recommended by the Commission appointed by the Botanical Club of the American Association for the Advancement of Science treats the matter of generic types more fully. Under Canon 15 (e) the statement is made that “the application to a genus of a former specific name of one of the included species, designates the

1 Naturg. der europ. Leberm. 2: 405. 1836; 3: 7. 1838.

— 26 —

type.” The type of the genus Calypogeia would therefore be C. fissa , because a former specific name of this species was colypogea , The fact that this specific name has an adjective form while the generic name includes an additional letter to convert it into a substantive can hardly be offered as an objection to this conclusion.

It thus becomes evident that neither Kantia nor Cincinnulus can be maintained, because both these genera were based upon a species which is clearly congeneric with Calypogeia fissa. It is equally evident that Raddi’s section A must bear the generic name Gongylanthus of Nees von Esenbeck, and that section B must represent the genus Calypogeia in its restricted sense. It is a noteworthy fact that these views are becoming more and more widely held by European botanists, and it is probable that they will be accepted by everybody in time.

The selection of Calypogeia fissa as the type of the genus is beset with certain difficulties but is based on definite principles. It introduces the stu- dent at once, however, to difficulties of a more subtle nature, due to the fact that European writers interpret C. fissa in very different ways. By some its validity is unquestioned ; by others it is considered a variety or even a mere form of C. Trichomanis ; by others the name has been applied to plants which are evidently distinct from those originally described by Raddi ; by still others, who recognize its distinctness jin a provisional sort of a way, transitional forms are alluded to which connect it with C. Trichomanis .

It has already been noted that C. Trichomanis and C. fissa were both based on Linnaean species of Mnium. Whether Linnaeus actually distin- guished these two species is doubtful. When he first published them he drew their characters entirely from the writings of his predecessors, and it is natural to assume that he based them upon these writings rather than upon a personal study of the plants themselves. As Howe justly remarks the only way in which these species can now be interpreted is by means of the prelinnaean descriptions which Linnaeus quotes.1

Under Mnium Trichomanis the only species referred to is the “ Mnium trichomanis facie, folio lis integris”oi Dillen;8 under M. fissum two spe- cies are quoted, viz. : “ Mnium trichomanis facie, foliolis bifidis" of Dillen * 3 and fungermannia terrestris repens , foliis ex rotunditate acuminatis bifidis: apertura pene visibili" of Micheli.4 Dillen’s herbarium is pre- served at Oxford, and the hepatics which it contains were carefully exam- ined by Lindberg over thirty years ago. The results of this examination have been published in three distinct reports, which appeared in 1874, 1877, and 1883, respectively. 5 U nfortunately these reports are at variance with one another, at least so far as Mnium Trichomanis and M. fissum are concerned. In all probability, however, the last report represents Lindberg’s latest views on the subject, and will be the only one here quoted.

Among the specimens labeled “ Mnium Trichomanis facie, foliolis infegrisi" LindLerg found two species, which he referred to Kantia caly- pogea (Raddi) Lindb. and K. fissa (L.) Lindb., respectively.1 2 3 Dillen’s figure, however, is said to represent the first of these species only. Among the specimens labeled “ Mnium Trichomanis facie, foliolis bifid is,” he also found the same two species but states that this time K. fissa is the one rep- resented by Dillen’s figure. Lindberg had already identified the second species quoted by Linnaeus under M. fissum as K. calypogea* but no impli- cation is made that this determination was based on a study of Micheli’s specimens. It should perhaps be emphasized that Kantia fissa Lindb. is by no means the same as Calypogeia fissa Raddi, but represents instead the species which is commonly known as C. arguta Nees & Mont. K. caly- pogea, on the other hand, was supposed to be the same as Calypogeia fissa.

It is clearly apparent from these statements that Mnium fissum L. is an aggregate species, but it is difficult to defend Lindberg’s action in restrict- ing the name fissum to one' of the component parts when Raddi had already appropriated it for the other. Perhaps it was because he considered the name more applicable to C. arguta than to what he called K. calypogea , perhaps because Dillen’s species was first published* earlier than Micheli’s. The second reason might have weight even at the present day, were it not for the fact that Dillen’s species, on Lindberg’s own showing, was based on an indefinite specific type. That Lindberg had an accurate conception of C. arguta is evident from the full description of this species which he pub- lished.4 That he had an equally accurate conception of Raddi’s funger- mannia calypogea is not so clear. Although he has never given a full description of his K. calypogea, he has repeatedly emphasized the inflores- cence as yielding important ditferential characters between this species and K. Trichoinanis. According to his statements K. calypogea is characterized by an autoicous inflorescence and K \ Trichomanis by a paroicous inflores- cence. Why he applied the latter name to a paroicous species after he had shown that the Dillenian plant upon which it was based was autoicous is a question raised by Howe, but this question becomes of minor importance in the light of some of the recent studies which have been made on C. Tricho- manis. From a study of a large series of specimens of this species, Douin5 has shown that its inflorescence is exceedingly variable, and that autoicous, synoicous and dioicous individuals occur along with the paroicous. In fact he regards an autoicous inflorescence as perhaps the most normal type for the species. These researches show that differences in the inflorescence are insufficient by themselves to separate species in this genus, and they therefore cast much suspicion on certain of Lindberg’s determinations, mak- ing it probable that some of the specimens which he called K. calypogea would

now be included under C. Trichomanis. For these reasons Lindberg’s inter- pretation of the two Dillenian species of Mnium can be accepted only with reservations.

At the present time the Continental botanists who recognize C.fissa as a species, although ascribing to it an autoicous inflorescence, no longer make this the basis for separating it from C. Trichomanis , and it is worthy of mention that they had ceased to do so even before the appearance of Douin’s paper. They emphasize rather certain peculiarities found in the leaves and underleaves. According to these writers the leaves are variously bidentate at the apex, the teeth being sometimes large and conspicuous and sometimes barely apparent. The underleaves are relatively small but are character- ized by being broader than long: they are deeply bifid with the sinus often extending beyond the middle, and their distant and usually blunt lobes, although sometimes undivided, often show a blunt supplementary tooth on the outside. One of the best of the recent descriptions is that published by C. Muller, of Freiburg.1

The British hepaticologists, who also recognize the species, emphasize the characters which have just been noted. For some reason, however, they call the plant Kantia Sprengelii (Mart.) Pears.,2 instead of applying to it the specific name of Raddi. The writer has been able to demonstrate this fact by comparing a specimen of K. Sprengelii, collected by Slater at Castle Howard in Yorkshire, with a specimen of C. fissa, collected by Levier in the vicinity of Florence. These specimens fully agree with each other. Whether they represent the Jungermannia Sprengelii of von Martius3 is a much more doubtful matter. This species was originally described from specimens collected near Nuremberg and was said to differ from J. Tricho- manis in its smaller and more deeply bifid underleaves with acute laciniae, and in its less frequently emarginate leaves. J. Sprengelii was recognized as a species by Dumortier4 and also by Hiibener, 5 but Nees von Esenbeck reduced it to a variety under C. Trichomanis and did not consider it very clearly marked. Until very recently the plant has been scarcely recognized by either French or German botanists. In 1899, however, Heribaud6 applied the name Sprengelii to what he considered a slender variety of Cincinnulus Trichomanis , growing among Sphagna, and Boulay7 and Douin8 have adopted it in the same sense. It is hardly probable that either this interpre- tation or the very different one arrived at by the British botanists was based on a study of the original J, Sprengelii , and a comparison of Pearson’s fig- ures with those of von Martius will show at once that they could hardly have been drawn from the same plant. Apparently a complete understanding of

J. Sprengelii has not yet been reached, but there seems to be no good reason for applying this name to the Calypogeia fissa of Raddi.

In the opinion of the writer C. fissa should -be recognized as a species, although its close relationship to C Trichomanis cannot be denied. All writers agree that the latter species is extremely variable, and it is prob- ably on this account that C. fissa has been so long overlooked or misunder- stood. Certain forms of C. Trichomanis are especially puzzling because they fail to show the characters of the species clearly and even simulate some of the characters which have been assigned to C. fissa. In typical forms the leaves are imbricated, undivided at the apex and scarcely or not at all decur- rent at the base, while the underleaves are large and orbicular with a shal- low apical sinus and rounded undivided lobes. Under conditions which interfere with normal development the leaves tend to become scattered and long-decurrent, thus changing their form completely, and the underleaves become smaller and more deeply bifid, and sometimes show acute divisions. The leaves even show a tendency at times to bebidentate, but this is usually most strongly marked on slender branches or at the base of a normal branch and is frequently associated with the formation of gemmae. In all proba- bility these bidentate leaves represent a reversion to a primitive or juvenile condition rather than a normal variation. In C. fissa the bidentate leaves are found on robust individuals, and although not invariably formed they are sufficiently frequent to yield a striking specific character. When they are found associated with small and deeply bifid underleaves there will be little danger of failing to distinguish the species. The synonymy of C. fissa may be given as follows:

Calypogeia fissa is known, to have a wide geographical distribution in Europe although its range has not yet been very definitely ascertained. It seems on the whole to flourish best in warm climates. Scarcely anything is

—30—

known about its distribution on this side of the Atlantic, where it seems to be much rarer. Pearson notes the occurrence of his Kantia Sprengelii in North America but gives no stations for it, and at the present time the author is able to record only two localities, viz. : Lafayette, Louisiana, Lang lots, and Devonshire Marsh, Bermuda, Mrs. Britton. Specimens from the first local- ity were distributed in Hep. Amer. 179 (as Kantia Sprengelii ), and the Ber- muda specimens have already been listed by the writer (as K. Trichomanis'). 1 Doubtless its true range is much more extensive than these meager records would seem to indicate.

There is perhaps some danger of confusing C. fissa with C. Sullivantii Aust.,2 a species which has an extensive range in the eastern part of the United States, especially along the Atlantic coast. C. Sullivantii is also characterized by bidentate leaves and by small and deeply bifid underleaves, each division of which commonly bears a small supplementary tooth on the outside. It is, however, smaller and more delicate than C. fissa and usually grows scattered among other plants of in loose thin tufts, instead of in com- pact mats. Its underleaves are often squarrrose or even reflexed, and their divisions and supplementary teeth are acute. In the majority of cases each division is tipped with a row of two or three cells and each tooth consists of a single projecting cell, but of course these numbers are subject to some variation. The cuticle of the leaf-cel s yields another differential character of importance, being minutely verruculose or striulate, instead of smooth as in C. fissa. C. Sullivantii seems to be the North American repre- sentative of the European C. arguta, the two species agreeing in nearly all respects. The most important difference between them is to be found in the teeth of the leaves. In C. Sullivantii these teeth are small and usually parallel with each other, the sinus being narrow: in C. arguta they tend to be larger and are more or less divergent, the sinus being broad and shallow. C. arguta has been reported from a greenhouse in Philadelphia,3 but there is no evidence that it. is native in this country.

Another North American species which is even more closely related to C. fissa than those so far considered is the West Indian Calypogeia portori= censis (Steph.) comb. nov. 4 This species was originally described from Porto Rican specimens but is now known from St. Vincent, Dominica and Jamaica. It seems to be most at home on logs in moist forests, especially at rather high altitudes, and under these conditions frequently forms pure mats of considerable extent. C. portoricensis is more robust than C. fissa , and its large leaves are rounded at the apex but yet bear two minute teeth sepa- rated by a shallow sinus. These teeth exhibit comparatively little variation in size. The underleaves are less deeply bifid than those of C. fissa and are attached by a more highly arched line; in most other respects the two species resemble each other closely. Yale University.

RHACOPILUM TOMENTOSUM (Sw.) BR1D.

Elizabeth G. Britton.

This genus and species are not recorded within the limits of the United States in Lesquereux and James’ Manual, though Rau and Hervey listed them in their catalogue of 1880. Specimens were first collected at Donaldson- ville, Louisiana, by Dr. Charles Mohr in November, 1856, and named for him by Dr. Carl Muller, who indicated its wide tropical and subtropical distribution. This species was described as Hypnurn by Swartz in 1788 and the type local- ity was Hispaniola, presumably from the western part of Haiti or Santo Domingo.

Scraps of the type material have been examined at Kew and the British Museum, and a duplicate West Indian specimen from Swartz has beenTound in the Mitten Herbarium. Drawings have been made by Miss Taylor from one of these co-types and from the specimens collected by Dr. Charles Mohr in Louisiana for the accompanying plate.

My first acquaintance with this species was made in Bermuda in Septem- ber, 1905, where it was found in great abundance in Church Cave, growingon damp rocks in shade and fruiting. Since then it has been found in Jamaica, and all the West Indian and Central American specimens have been care- fully studied and compared. This seemed imperative for the names, syno- nyms and varieties given by Paris Index Ed. 2. 4: 164. 1905, indicated that there was a mixture and very wide distribution with considerable variation.

The synonymy of the North American species is as follows:

MISS CLARA E. CUMMINGS.

Hunnewell Professor of Cryptogamic Botany at Wellesley College.

On the day of our recent Chapter meeting at Columbia, Dec. 28th, one of our most valued members died. There is a brief notice in “ Science,” Jan. 11, 1907, page 77. The following obituary appeared in the “Boston Evening Transcript,” Monday, Dec. 31, 1906:

MISS CLARA E. CUMMINGS.

Hunnewell Professor of Cryptogamic Botany at Wellesley College.

Miss Clara Eaton Cummings, Hunnewell professor of cryptogamic botany, Wellesley College, died in Concord, N. H., Friday, after an illness of sev- eral months. The funeral services were held Dec. 30th, at the house of her niece, Mrs. Worthen, 24 Fayette street, Concord, N. H.

Professor Cummings has ;been to a peculiar degree identified with the history of the college, which she so loyally served. Entering as a stndent in

—34—

1876, a year after the first opening of Wellesley, she at once showed so marked a talent for the study of botany, especially for the identification of cryptogamic flora, that she was retained as a permanent member of that department of study, bearing the title of curator of the museum, 1878-79, instructor in botany, 1879-86. After a period of study in Zurich, Miss Cum- mings returned to the college as associate professor of cryptogamic botany. In 1905 she became Hunnewell professor of botany, with temporary charge of the department. In 1906 her title was changed to that of Hunnewell pro- fessor of cryptogamic botany, in recognition of the closely specialized work in which she had reached distinction, and with the hope that freed from the burden of administrative cares she would gain strength for new enterprises in her chosen field. Her health, however, proved to be seriously impaired.

Among the published works of Professor Cummings are “Lichens of Alaska and Labrador;” she also edited “ Decades of North American Lich- ens,” and was associate editor of “ Plant World;” she was fellow of the Amer- ican Association for the Advancement of Science; a member of the Society of Plant Morphology and Physiology (vice president in 1904), of the Mycologi- cal Society, Torrey Botanical Club, Boston Society of Natural History and Boston Mycological Club. Her studies were quickened and exalted by a passionate love of nature in its loftier forms. Especially dear to her was the mountain region of North Woodstock, N. H., her summer home. To those who knew her in those inspiring scenes, she seemed one with the genius of the place. Affectionate, gentle, trusting, brave of heart and blithe of spirit, she was in her life blessed by the devoted attachment of noble friends to whom her death brings lasting sorrow.”

LESCURAEA FRIGIDA IN VERMONT

Annie Lorenz.

The species in question was collected by Dr. A. J. Grout and the writer on Mt. Mansfield, Vt., July 6, 1906, during the summer meeting of the Ver- mont Botanical Club.

The specimens grew on the eastern face of a granite rock, on the path to the Ice Cave on the “Upper Lip” of the mountain, at about 4300 ft. alt.

They were of a bronze-golden color, quite closely appressed to the rock, and were sterile. They were hastily collected as Pterigynandrum, but upon examination by Mrs. Britton and the writer it proved to be a Pseudoleskea of such puzzling appearance that it was submitted to Dr. Best.

He reports it as Lescuraea frigida Kindb. very close to his own Pseudo- leskea substriala, which however is a British Columbian species, and he pre- fers to keep Kindberg’s name for the eastern form.

Lescuraea frigida Kindb. Eu. & N. Am. Bryineae 1: 26, 1897.

“ Leaves from subovate base nearly gradually narrowed to the long sub- ulate or filiform-pointed acumen, recurved to it and distinctly decurrent; cells sublinear except the quadrate alar ; costa sometimes long-excurrent. Stem- leaves generally entire; branch-leaves serrulate at the whole acumen, some- times short-acuminate and faintly mamillose. Capsules unknown. Stem

— 35 —

subpinnate. Tufts dark brown or blackish, not glossy. Very distinct in ser- rulate branch-leaves and very narrow leaf-cells. Amer. r. Can., Northern Labrador: Macoun, 1896.”

Lescuraea frigida was described by Kindberg from specimens collected at Clearwater Lake, northern Labrador, in 1896, (Mac. Cat. VII. p. 273. 1902.) but this is the first report from New England.

It ought to occur among the White Mountains, as well as in Vermont as it is not dependent upon limestone, but being sterile, it has probably hitherto been overlooked. Hartford, Conn.

REPORT OF THE SULLIVANT MOSS CHAPTER MEETING.

The fourth public meeting of the Sullivant Chapter was held at 2 p. m, on December 28, 1906, in Schermerhorn Hall of Columbia University, New York City, in connection with the American Association for the Advance- ment of Science. Owing to a most interesting discussion, under the direc- tion of the Botanical Society of America, held in an adjoining room at the same hour, the number in attendance varied, many coming to us before the hour of the formal opening and others giving a portion of the time. Through the kindness of Prof. Underwood, a room was placed at our disposal for the day. Mr. Chamberlain and Miss Haynes were present early in the morning to arrange the exhibit. The walls were hung with mounted sheets of mosses, hepatics and lichens, and with photographs of noted scientists.

The exhibits were as follows: Mrs. M. L. Stevens showed two volumes

of mosses collected during the summer of 1906. Miss Alice C. Kendall sent water-color sketches, with mouuted specimens of the mosses colored. A simi- lar book of water-color sketches was sent by Mrs. Dunham. Mr. Hill, of New Westminster, B. C., sent a valuable series of mounted mosses and lichens, accompanied by notes. These specimens are to be added to the Chapter Herbarium. Mr. Hill intended to present a descriptive paper, but a serious accident prevented its completion. Miss Cora Clarke was present and presided over a unique exhibit, her own invention. Numerous herbarium sheets, each devoted to a single species of moss, were ruled into twelve squares marked for the months of the year, and specimens of a moss from a given locality, collected during as many different months as possible, were mounted in the proper squares. The Monthly Chart thus shows, at a glance, the varying stages of the moss and the comparative development of different species. The execution of the work was most artistic. Miss Lorenz exhib- ited a series of mounted mosses from Willoughby, Vermont. Microscopes were furnished and Miss Haynes presided over her exhibit of slides of rare hepatics and of original drawings. Mrs. Smith exhibited a series of artist’s drawings with the half-tone proofs from each, also plates from original specimens and from photographs showing the various methods of illustrating The Bryololgist. Mr. Rapp presented a series of specimens collected in Florida Prof. Holzinger sent a large number of duplicates from his Musci Boreali Americani Exsiccati, to be given away as souvenirs. Last, but by no means least in interest, was a long line of photographs of native as well

— 36—

as of foreign lichenists, loaned by Prof. Bruce Fink, who also presented to the Chapter sixty rare lichens.

The meeting was called to order by the President, Mr. Edward B. Cham- berlain, and the following program offered, the reading of reports and other formalities being dispensed with.

Dr. A. W. Evans, “ Species of Calypogeia New to North America.”

Miss Annie Lorenz, “On the Genus Catharinea in Hartford County.” A discussion followed this paper.

Mrs. E. G. Britton gave an informal talk on matters of general botani- cal interest and exhibited mounted specimens illustrating the beautiful moss flora of Jamaica, with comments on some West Indian genera. She passed around for examination a rare fossil moss, found by Prof. Cockerell in Nebraska, which she has determined as a species of Grimmia. This is the fifth fossil moss that has been described and the first ever found in fruit.

Miss Emmerson described a possible new species of moss, Andreaea Toc- coae, showing specimens and drawings.

Prof. Bruce Fink gave a brief survey of the noted lichenists, whose photographs he exhibited, with a tribute to Wainio, and followed this by an interesting account of recent collecting tripsin the Canadian Rockies.

Dr. Grout gave an informal talk on the ways in which amateurs may render valuable contributions to botany.

Mr. R. S. Williams closed the formal program with an account of the recent purchase of the Mitten Herbarium by the New York Botanical Garden, and showed various genus covers illustrating Mitten’s method of work. A discussion followed.

On account of lack of time, the following papers were read by title: “Notes on Pogonatum tenue (Menz.) Britton,” by B. F. Bush: “ A List of Missouri Mosses, with Notes,” by Rev. Charles H. Demetrio: “Common Mosses of Central New York,” by Mr. B. D. Gilbert: “ Moss Notes,” by Mrs. Lamprey, and “A New List of North American Species of Parmelia,”by Mr. G. K. Merrill. Much to our regret, Mr. Reginald Heber Howe, Junior, was detained by illness and, therefore, his paper with lantern illustrations was not given. Mrs. Harris, too, was unable to present her paper on account of illness. Dr. Best, though urged, declined to speak, saying that he came only to enjoy the good things prepared.

At the close of the regular program a delightful social hour was passed, greeting old and new friends, and examining the exhibits.

A MEMOIR OF CLARA E. CUMMINGS.

Bruce Fink.

To the writer has been assigned the sad duty of adding to the statements that have already appeared regarding our lamented member of the Sullivant Moss Chapter. More especially, the request made was that something should be written regarding her work as a botanist. It was my good fortune to have met Miss Cummings several times at Wellesley College and elsewhere, so that to the impressions that came from correspondence was added that knowledge of 'personality which comes only through meeting a co-worker. That hers was a rare spirit was manifest, both in the personal touch and in correspondence. There was a very manifest unselfishness, frankness and devotion to the work that she did because she loved it. The earnestness patience, enthusiasm and friendliness which made her the ideal teacher also conduced to her success Jn aiding in the advancement of botanical science. All who have come into intimate relations with her in either capacity must have felt her delight in service.

Miss Cummings was a botanist in the highest sense, thoroughly in sym- pathy with all that is best in her chosen science. Her reputation was by no means confined to our own country, but she was well known in Europe through personal acquaintance and correspondence. She will be remembered especially on account of her contributions to Lichenology, and it is in the main our present task to place before botanists a somewhat adequate view regarding her labors in this special field; but we could do no greater injustice than to do this without referring to her more general knowledge of botany, and to the strength of character and breadth of culture and sympathy, which touched the lives of those who .came in contact with her as friend, teacher or co-wdrker in botany.

We have read with keenest appreciation the statement in the “ Wellesley College News”, for February 6, 1907, regarding Miss Cummings’ life work as a teacher in Wellesley College and as a contributor to botanical reseach, and we can only hope to enlarge somewhat upon the latter. Miss Cummings’ first paper was the “ Catalogue of Musci and Hepaticae of North America, north of Mexico,” which appeared in 1885. Just when she began her work on the mosses can hot be ascertained, but I find in my herbarium specimens of her “New England Mosses ” collected as early as 1880, and specimens of her “Mosses of North America” collected early in 1884. The packets are not numbered, and the writer does not know how many plants were distributed in each of these two sets of exsiccati. Their existence, however, if it may be assumed that the same accuracy which characterized her later work on lichen exsiccati obtained, demonstrates that their author possessed a knowl- edge of mosses before she began her more extended work on lichens.

The March BRYOLOGIST was issued March 1, 1907.

Miss Cummings also issued a set of “New England Lichens.” Just when she began the distribution of this set, also unnumbered, is not known to the writer, but he finds in his herbarium specimens from these exsiccati collected in 1884. This indicates that she possessed a considerable knowl- edge of lichens at this time, and it appears that the surroundings of her New England home inspired an interest in mosses and lichens quite early. Born at Plymouth, New Hampshire, July, 1855, doubtless Miss Cummings was at work on these plants before or during her years as a student in the New Hampshire Normal School in her native village, previous to entering Welles- ley College in 1876. At least it is stated that she showed excellent ability in the determination of lower plants at this early date, and we are justified in the conclusion that there was an earlier period of preliminary study of these plants.

The list of papers on lichenology, written by Miss Cummings and pub- lished in her own name contains only three titles, all published during the last five years of her life. The other papers given in the bibliography con- tain lists of lichens made by her and published in papers by other botanists, either from material which she had determined or examined, or as compila- tions from the work of Tuckerman, Willey and others. Whatever part she may have had in the making of these lists, the labor involved in their pre- paration was doubtless insignificant in comparison with that which must have been necessary in the preparation of exsiccati and “The Lichens of Alaska.”

The labor involved in issuing “Decades of North American Lichens” and “ Lichenes Boreali-Americani,” together with the large amount of determining for others that Miss Cummings kept up for years in connection with this work, is surely her best contribution to lichenology, — a contribu- tion quietly performed and much of it entirely unknown, except to the per- sons for whom she must have spent many weary hours in determining their specimens. It is well known that the names of A. B. Seymour and T. A. Will- iams have appeared in the two sets of exsiccati, but these sets of lichens are after all very largely the work of Miss Cummings. In conjunction with Mr. Seymour, she began issuing the decades in 1892, and the sets reached three hundred and sixty numbers. The second edition, “ Lichenes Boreali- Americani,” began to appear in 1894, and the name of T. A. Williams was added as co-worker. This series of exsiccati reached two hundred and eighty numbers. Early in 1905, Miss Cummings began negotiations with the writer regarding taking the place of Mr. Williams in issuing the sets of exsiccati, but because of the long-continued illness of the originator of the sets, the work did not go forward. On account of these later plans, Miss Cummings’ only list of the two sets of exsiccati, arranged alphabetically by genera, has been in the hands of the writer since August, 1905. This list might be of some interest, but it is too long to include in the bibliography at the close of this paper.

I am able to testify from personal experience to the great care which Miss Cummings exercised in the determining of lichens forher friends. Our

—39-

correspondence began in February, 1893, when the writer sent specimens to her asking her views regarding some of his determinations. From that time forward, about sixty letters were received and preserved, besides whatever unimportant ones may have been destroyed. In all of the discussions regarding species, Miss Cummings showed care and accuracy. She had access to the Tuckerman herbarium, and every uncertain thing was subjected to careful comparison before she ventured a positive statement, whether col- lected for her exsiccati or sent for her opinion of the species.

This correspondence was always interesting and helpful to the writer, and is but one of the many instances in which Miss Cummings sacrificed herself without stint for the benefit of her friends. Some gleanings from these letters and postals received may be given here without impropriety. There was the very frequent appeal to try to interest others in the study of lichens, and the statement that she was sacrificing herself in issuing exsiccati and in her correspondence for the good of the science of lichenology and for the love of her work. As early as 1900 she wrote of being hard at work on the Alaska lichens, and especially the lichens of the Harriman expedition. The writer has since examined critically many of these Alaska specimens passed on by Miss Cummings and finds in them even greater evidence of careful work. The Pringle Mexican lichens were mentioned several times, the purpose being to make a series of special sets of them. This seems never to have been accomplished. In 1894, when the writer was inclined to turn from lich- enology, there was made the same earnest appeal which no doubt came to many another worker to continue in the work. The offers to loan literature and aid in any possible way continued even after the time in 1899, when came the first statements regarding ill health. She wrote several times of her work which appeared in papers by other persons, among other things, stating that she did all of the work on the lichens in Charles Mohr’s “ Plant Life of Alabama,” except the preliminary statement.

Besides her other work, Miss Cummings found time to do a large amount of lichen collecting in such widely separated, portions of the United States as New England, Florida, Colorado and California. She also col- lected on adjacent islands, and I find in my herbarium an occasional speci- men of her collecting in Switzerland and Italy as long ago as 1887.

Miss Cummings was conservative in all of her work. Her conservatism appears most plainly in her review of Dr. Albert Schneider’s “Text-book of Lichenology,” and in her latest and best published contribution to lichen- ology, “The Lichens of Alaska.” In the paper just named she clings very closely to the Tuckermanian view regarding genera, in . such genera as Buellia, Biatora and Lecanora, placing species having very different spore characters in the same genus. In the treatment of the Cladonias only does she depart to any considerable extent from Tuckerman’s method, her work here following Dr. Wainio more largely. The same conservative spirit manifests itself in her small number of new species, the two published in her last contribution being the only ones due to her work, though she had col- lected much where others seem to find new species very readily. A more

-40-

radical person might have had a larger output, but with her nothing was to be done hastily, and no changes were to be made without most careful con- sideration. Her work was constantly gaining in quality and influence as is readily enough seen in improvements in manner of issuing the exsiccati and in the character of her latest publication. In her early death, December 28, 1906, at a time when she had many unfinished plans for work in lichenology and was most able to do efficient work, lichenology and botany sustain a severe loss.

Others have written of Miss Cummings’ life work as a teacher at Welles- ley College, of the recognition given her. and of various honors conferred upon her. So it only remains to append a list of her papers, either published wholly in her own name, or appearing in the writings of others. The two numbered sets of lichen exsiccati are added after the papers, but not the earlier distributions of mosses and lichens.

FURTHER NOTES ON CLADONIAS. X.

Cladonia decorticata and Cladonia degenerans.

Bruce Fink.

As to the relationships of Cladonia decorticata, it has been considered a variety of Cladonia pyxidata , to be considered in the next paper of this series and has also been placed as a variety of Cladonia pityrea. From material in the writer’s herbarium, it is apparent enough that specimens might easily be confused with little-branched and decorticate conditions of Cladonia squamosa as well as with some conditions of Cladonia furcata scabriuscula. It seems to the writer that, of the species considered in this series, the nearest relationship is with Cladonia squamosa, though Dr. Wainio h'as placed several of the other species already considered or to fol- low in the series between. The relationship with Cladonia furcata scabrius- cula, especially its less branched and more decorticate forms, seems quite near, while that with Cladonia pityrea is not at all close. ' Examination of an excellent series of European specimens of Cladonia pityrea , received from L. Scriba, reveals a closer relationship than the last, and yet it does not appear that Cladonia decorticata should be confused with Cladonia pityrea.

- 42—

A practical difficulty in distinguishing between certain forms of Cladonia degenerans and Cladonia gracilis dilatata is mentioned below, and the writer has also had difficulty in separating certain specimens from forms of . Cladonia crispata. However, this difficulty will not often be met.

It is certain enough that the two species considered in this present paper are not so closely related to each other, as is each one to some other Cladonia , but it is impossible, in the present state of knowledge of the genus, if at all, to place the Cladonias all in any probable continuous genetic series.

Fink). Wainio’s distribution adds Port Clarance, Greenland, Newfoundland, Miquelon, White Mountains, Massachusetts, Virginia and several localities in British America. The above distribution indicates that the plant is to be looked for throughout the northern portion of the United States and north- ward, but still it is not well known. Found in all the grand divisions.

Dr. Wainio has seen fit to divide the species into four forms, two of which he has recognized in material sent him by the writer from Minnesota. Of eight of these specimens submitted, Dr. Wainio referred two to the first form below, one to the second below and five to the species without attempt- ing to refer to a form. Dr. Wainio admits in his Monograph that the four forms are scarcely constant or distinct enough to be of any taxonomic value. So we can do no better for the present than to record below two forms to which our three American forms have been referred by the best authority on the Cladonias. Future world-wide study of the species may enable workers to understand the species and its varieties.

Cladonia degenerans euphorea (Ach.) Nyl. Syn. Lich. i: 200. 1858.

Podetia without squamules, or the lower portion sparsely squamulose, the sterile cups regular and the fertile ones subregular, sometimes proliferate.

The plants determined by Dr. Wainio were collected at Kettle Falls and at Harding, both in northern Minnesota. Not known elsewhere in America. Well known in Europe One of our specimens submitted to Dr. Wainio looked suspiciously like Cladonia gracilis dilatata , and was submitted a sec- ond time with the result that it was returned simply Cladonia degenerans. We can not question Dr. Wainio’ s determination and now see why he placed the plant as he did, but the practical difficulty for the ordinary worker in dis- tinguishing such forms is very great. For the illustration of this form, we give in one figure plants from each of the two collections. A glance at the figure will show those acquainted with C. gracilis, which plants of the fig- ure resemble it most strongly.

Cladonia degenerans cladomorpha (Ach.) Wainio, Mon. Clad. Univ. 1: 141. 1894. Podetia without squamules or sparsely squamulose toward

the base, cup-bearing, the cups irregular with lacerate and sometimes proliferate margins, or sometimes abortive or disappearing in the pro- liferations.

A single collection made at Emo along the northern boundry of Minne- sota, was placed here by Dr. Wainio. Not known elsewhere in America. Frequent in Europe. Oxford, Ohio.

CATHARINEA IN HARTFORD COUNTY.

Annie Lorenz.

Hartford County, in the Connecticut valley, lies chiefly in a Triassic region, although the Eastern Highlands enter the southeast corner of the county at South Glastonbury.

The main formations are sandstones and shales, but the trap dykes are the most conspicuous features of the landscape. The country east of the river is largely sand-plain, extending to the foothills of the Highlands. This, with its western exposure, gives East Hartford a rather warmer climate than that of the western side of the river, and produces a flora in some respects curiously resembling that of the shore of Long Island Sound. This makes a good variety of soils, as the trap, a lime-and-soda feldspar, furnishes the modicum of lime which is necessary to so many species.

From a geological standpoint, mosses may be roughly divided into three classes according to their habitat: those requiring lime in the substratum on which they grow ; those that sedulously avoid limestone, Kalkmeidend , as the Germans say, and those that are not particular. Kerner holds that it is not that certain species like the limestone, but that they can tolerate it, while the others cannot. However that may be, a region containing any lime- stone has always a much richer flora than one without. This applies with equal emphasis to the Hepaticae.

The third class above mentioned includes most of the commoner cosmo- politan mosses, and among them the Catharineae.

-46-

Of our three eastern Catharineae, all occur in the county. C. augustata is much more common than C. undulata, while in England the reverse is the case.

Dixon says that the two are separated “by a combination of characters rather than by any one clearly-defined character.”

C. augustata chooses drier ground, and usually fruits abundantly, while C. undulata prefers to grow in big cushions along the edges of shady swamps or streams, and does not fruit as freely as the former. Then, C. augustata usually has more or less dark red about it, particularly about the fruit, and the leaves are of an olive-green, while C. undulata has fruit of a brown ochre, and clear green leaves (about Hooker’s green No. i).

No. 5 of the writer’s specimens are male plants of C. undulata , or rather the first flowering of the young plants, as the species is paroicous. They were collected in June ; the antheridia are full-grown, but still immature. The perigonial bracts resemble the leaves of Hylocomium brevirostre in size and shape, they have five lamellae, like the leaves.

No. 199 approaches C. imdulata v. minor W. & M. It grew on an old stump, but is good C. undulata. The plants are less than 1 cm. high, lamellae 5, capsules brown, erect, 2-3 mm. long, seta 2-2.5 cm.

Catharinea crisp a, while probably common along the Sound shore, is not so inland. East Hartford, collected Mr. C. A. Weatherby, is, according to Mr. Collins, the first station reported from the State, but it is undoubtedly overlooked, or not reported from other places.

East Hartford has the very sandy soil which C. crispa requires, and it has been found in two quite different parts of the township, in big patches beside brooks in the woods. Dixon says that the plants are frequently buried up to the tops of the stem in sand, which is the case with the plants at the School St. station. He further gives its habitat as “ sides and beds of rocky streams, among grass or in sand.” Dr. Grout says, “Common in swamps along the south shore of Long Island.”

The East Hartford stations are in the woods, on sandy banks of streams, but not in swamps, nor is there a rock larger than a drift pebble in East Hartford. Sterile C. crispa can easily betaken for Mniumhornum, which is more than likely to be its next neighbor on the bank where found, but lamellae can be demonstrated with a little care, although they are few, 1-4, and more or less inconspicuous.

The capsules mature slightly later than those of the other species, they are dark olive instead of dark red.

These data apply to the typical forms, rather than the abnormal ones, caused by variations in climate or habitat.

NOTES ON RECENT LITERATURE.

A. J. Grout.

Conocephalum conicum (L.) Dum. ' Ever since I was a mere lad I have noticed a pungent aromatic smell when traveling along the moist banks of our Vermont brooks in search of trout or other pleasures, but I never discov- ered the source of the odor until this last summer (1906). The odor is given forth by the crushed or bruised fronds of Conocephalum. So far as I can ascertain this remarkably strong odor is not mentioned in any of our Ameri- can works. Lett, in his “ Hepaticae of the British Islands.” mentions the odor as comparable to that of bergamot. In Beihefte Bot. Centralblatt, 181: 327-408, 1905, Eugene Bolleter has a very complete account of exhaus- tive studies on this plant: of this paper we hope soon to have a full review. In it the odor of the plant is mentioned but it is called “turpentine-like.” Go and smell and take your choice between turpentine and bergamot. To me it is like neither, but has the pungency of turpentine without its quality.

We are interested to note an article to help beginners in the study of mosses, entitled, “A Word for Mosses,” by Prof. Wm. W. Bailey, in the Am. Botanist, Dec. 1905. After a rather brief description of methods of study and an explanation of some common terms, comes a list of living students of merit We recommend the perusal of this list to those who wish to become familiar with the methods of the editor of the Am. Botanist, for we attribute some obvious peculiarities of this list to the editor, not the author.

Freaks in Mosses. In the Bot. Gazette for August, 1903, Miss Mary C„ Bliss, of Wellesley College, records finding an archegonium of Poly trie hum juniperinuin with two distinct venters, one above the other, “The lower ven- ter containing two nuclei, which probably represent the egg cell and the ven- tral canal cell. The upper venter has doubtless been developed from the first neck canal cell and contains but a single nucleus. Directly above in the neck of the archegonium, is the nucleus of second neck canal cell.” In the February number of the same journal W. C. Coker recorded the occurrence of two egg cells in the archegonium of Mnium. From her. own observations and those of Coker, Miss Bliss is led to believe that the neck canal cells are potential egg cells and that the egg cell and the neck canal cell have a com- mon origin.

In Hedwigia, 45: 178-181, plates X and XI, Prof. W. Monkemeyer describes a number of interesting freaks, such as a cleistocarpous capsule of Bryum saxonicum Hagen, and ten abnormal capsules of Pogonatum nanumr varying from completely cleistocarpous to operculate, with traces of a peri- stome attached to the lid. All the capsules of Pogonatum were globular and had broken through the calyptra instead of tearing it off at the base and car- rying it up on the top of the sporophyte in the normal way. The setae were bent and the hairy calyptras attached to their sides. Those of our readers who have read Dr. R. H. True’s paper on “The Physiology of the Sphoro- phyte of Funaria and Mnium” in Beihefte Bot. Ceritralblatt, 19l: 34-44, 1905, will at once infer that the entire abnormality may have followed from the breaking through the archegonium by the young sporophyte and the conse- quent inability to develop, like that found by True in Funaria when the operculum was removed.

A full account of Dr. True’s conclusions will be published in the Bryol- ogist at an early date.

Prof. Monkemeyer also records several cases of two or three peristomes in the same capsule, one above the other. In one case in Dicranella varia, between the urn and the true operculum was inserted a hollow cylinder: inside this were two peristomes attached by the slender tips of the teeth, the upper being inverted with its base attached to the lid In a specimen of Bryum saxonicum there were two hollow cylinders, one above the other, and three peristomes, the two upper being inverted. In the same species there was also a case like that of Dicranella varia but the upper portions of the teeth were not so fully developed. There was an annulus at the base of each peri- stome but the inner peristome appeared as merely a delicate yellow mem- brane.

In the Botanical Gazette for August, 1906, Prof. George J. Peirce, of Stanford University, gives an account of work with “ Anthoceros and its Nostoc Colonies,” and of field observations on the same. He concludes that A nthoceros does better without the Nostoc, although he is not able to say that the Nostoc is parasitic.

Authentic and complete lists of mosses of limited areas are of great value and interest to the systematist, and also to the general biologist by rea- son of the bearing of plant distribution on the problems of evolution. Of course absolutely complete lists are an impossibility, they can only be com- plete as far as recorded observation goes.

The Bryophyta and Pteridophyta of Pennsylvania by the late Prof. T. C. Porter, edited by Dr. John K. Small, and published by Ginn & Co., is one of the best of such lists. It seems unfortunate to the reviewer that certain changes in nomenclature have been made, but in spite of the efforts for uni- formity there seems still to be a wide variation of taste in the matter.-

In Rhodora for May, 1906, A. LeRoy Andrews gives a list of “ New England Sphagnaceae, ” with some notes. It may be of interest to our readers to know that Mr. Andrews has consented to take up work on the Sphagnaceae with the Sullivant Moss Chapter on his return from Europe.

In the same journal for July, 1906, Mr. J. Franklin Collins gives a simi- lar list of th & Buxbaumiaceae, Georgiaceae and Polytrichaceae. Some refer- ence to this list has previously been made in the Bryologist (9: 101) and some extracts from his notes reprinted.

Century III of this splendid series, published by Dr. A. J. Grout, Brook- lyn, N. Y. , has just been completed, the twelfth fascicle having come to hand at this writing, Jan. 30, 1907. A general review of this work is demanded at this juncture, both on account of the work itself, and also for the benefit of all whom the author has placed under lasting obligation by his long sus- tained, painstaking effort on this collection. This work has been made pos- sible only by much self-sacrifice on the part of the author, aided, to be sure, by the generous help of all contributors in various parts of the country. The writer has himself contributed a number of species, but he knows from experience that the collecting is the lesser task by far. Dr. Grout’s work looms up larger and larger in my appreciation as I experience what such a publication requires in time and sacrifice of pleasures and neglect of routine and social duties.

This twelfth fascicle is accompanied by a four page pamphlet, more than three pages of which are taken up with the alphabetical enumeration of Cen- turies I— III. The last page contains critical notes on Century III. Simi- lar lists of notes accompanied Centuries I and II after each was completed. Since this series is widel}r distributed among European as well as American bryologists, there is no doubt that further critical notes and certainly critical references will appear in the future in bryological journals on both sides of the Atlantic. No scientific institution in which work along this line is carried on can well afford to do without this help. Time and lack of space forbid the enumeration of the new and rarer species so far distributed. Any one really interested and desiring to know about this collection will surely

wish to see the author's full alphabetical list, which can be obtained by apply- ing to the author at 360 Lenox Road, Brooklyn, N. Y. For the purpose of stimulating field workers further to turn their attention toward Dr. Grout’s needs, for he doubtless proposes to continue this series, and also to show rather definitely the geographical gaps in which new collectors are desired to arise, I have compiled the following tabulation showing the distribution of States and collectors represented :

Maine — Miss Alice L. Crockett.

Vermont— Mrs. J. B. Clapp.

Vermont, New Hampshire, New York — A. J. Grout.

Vicinity of Catskill Mountain House— C. F. Austin and E. A. Rau.

New York — B. D. Gilbert, J. W. Martens.

Pennsylvania— D. A. Burnett.

Connecticut— Mrs. J. D. Lowe.

Massachusetts— Miss Cora H. Clarke, Mr. Walter Gerritson, Mr. J. W. Huntington.

Maryland— Wm. R. Maxon.

District of Columbia — Miss Mary F. Miller

South Carolina — Prof. H. A. Green.

Georgia — Mrs. A. P. Taylor.

Florida — S. Rapp.

Missouri— N. L. T. Nelson.

Illinois— L. M. Umbach, F. E. McDonald.

Wisconsin — L. S. Cheney, J. M. Holzinger.

Colorado — J. M. Holzinger and C. F. Baker. (This should be the read- ing on the label No. 176.)

Montana — J. M. Holzinger and J B. Blake.

California — M. A. Howe, M. S. Baker and F. P. Nutting.

Oregon — A. S. Foster.

Washington — J. W. Bailey, A. S. Foster, T. C. Frye. J. B. Flett.

British Columbia — J. W. Bailey, E. Wilson.

Canada — H. Dupret, J. Macoun.

This list shows that about thirty-four collectors, working in twenty-two states and provinces have co-operated with the author, Dr. Grout, in achiev- ing this notable result. Though much has been accomplished, a moment’s consideration of the great tracts still awaiting even cursory exploration will convince any one that the half is not yet done. Less than half the number of states of the Union, and only a small corner of the vast Canadian region, to say nothing of Alaska. The choicest, rarest things are yet waiting to be discovered, among them doubtless scores of species still undescribed. It is safe to state that one lifetime, even with five times the support so generously given to the author, will hardly suffice to approximate the completion of this task. Yet whatever fraction of it is done is a distinct gain for bryology; for it is sure to make possible a uniform understanding of critical and little known species by furnishing to most widely separated investigators uni- formly identical material recognized as typical by the most competent stu-

-51-

dents of mosses in the world. The possession of such a classical collection by comparative beginners in this study, at any price, is a privilege which is now for the first time available. It will aid in the more rapid mastery of the rudiments and in earlier initiation of the tyro into the critical study of diffi- cult groups of mosses, a field in which the workers are as yet all too few, and for which it is hoped the younger generation of students will train themselves in rapidly growing numbers by such splendid aids as Dr. Grout’s North American Pleurocarpi.

DIE EUROPAEISCHEN TORFMOOSE.

Nachtragsheft zu den Europaischen Laubmoosen, beschrieben und gezeich net von Georg Roth. 80s. II Taf. Leipz. (Engelmann) 1906. Preis M. 3.20.

Roth has given us in the above a supplement to his two volumes upon the European mosses, in which the sphagna were lacking, with descriptions and illustrations upon the same plan. The book fills a much felt want, as Braithwaite’s admirable work (1880) is inadequate to an understanding of the forms that have been segregated into species in the past few years, while the illustrative work of Warnstorf has been scanty, diagramatic and in so far unsatisfactory. The drawings of Roth are on the other hand realistic in the extreme, treat admirably the critical points, notably the stem leaves and the pore system of the branch-leaves, and should help to dissipate the uncer- tainty with which bryologists have been prone to regard the group. Of the fifty-seven described European specimens forty-three are definitely known from North America, while most of the others are to be expected there, so the work is hardly of less value to the American than to the European bryolo- gist. The work follows in the main Warnstorf, with consideration of the author’s own observations and other contributions upon the subject, a very good bibliography of which is given at the outset. Especially has the author sought to make available the work of Roll, which has been neglected owing to its divergent and isolated nomenclature.

As compared with Warnstorf’s late's t treatment the following new names are to be noted: S. Schliephackei (Roll) Roth, including as variety S. Schultzii Warnst., S. pseudorecurvum Roll and S. pseudocuspidatum Roth, an attempt as the names indicate to dispose of some of the troublesome con- necting links between 5. cuspidatu77i and 5. recurvuTTi. S . pUTigens Roth inserted between the already closely related S. I7iu7idatu77t Russ, and S. Gravetii Russ. (=S. auricu latu77t Schpr.), S. turgidwn (C. M. ) Roth for Warnstorf s S. crassicladu77i , and S. cor7iutu7n Roth for what Warnstorf had treated as typical S. rufesce7is Bryol. Germ. As an apparent omission, I would note the failure to allude to the recently proposed species 5. ochracewTi Glowacki from Carinthia (Jahrb. d. Naturhist. Mus. von Karnten, XXVII, Klagenfurt, 1904, accordance to reference).

An illustration of the pore-structure of the American S. Mendocmeiwi Sulliv. is contributed by way of pointing out its distinction from the several

— 52—

related Scandinavian species detected by Harald Lindberg. A valuable hint as to staining of plants for demonstration of the pore-structure is appended, while the prefatory note that the author's drawings of non-Euro- pean mosses preparatory to his publication of the world’s species have reached the number of 3,940, is of general interest. The book is to be com- mended as well for its cheapness as its excellence to all interested in our own sadly neglected American sphagna. A. LeRoy Andrews.

BOOK NOTICES.

Lichens of Mount Monadnock, New Hampshire, by Reginald Heber Howe, Junior. (Reprint from Am. Nat. 40: 661-665. Sept. 1906.)

This is an annotated list of seventy-one species and varieties collected by the author April 5th and 6th, 1906, upon the slopes and summit of Mount Monadnock (3166 feet) in Cheshire Co., N. H. The notes give the distribu- tion in the Transition, Sub-Canadian, and Canadian floral zones occurring on the mountain, the relative abundance of each species, and the substratum. Specimens of all species listed are in the author’s herbarium.

Census Muscorum Australiensium. A classified Catalogue of the Frondose Mosses of Australia and Tasmania, collated from available Publications and Herbaria Records, by the Rev. W. Walter Watts and Thomas White- legge, F. R. M. S. In two parts. (Proc. Linn. Soc. N. S. W. 27: Pt 3, Supp. pp. 1-90, and 30: Pt. 4, Supp. pp. 91-163. Sidney, N. S. W. 1902 and 1906.)

These two pamphlets, which are issued under the auspices of the Linnean Society of New South Wales at the price of five shillings sixpence for the two, comprise in convenient form a list of the Australian acrocarpous mosses, including the Sphagnaceae and Andreaeaceae. The introduction reviews briefly the circumstances that led to the preparation of the list, and the work which has been done upon the moss-flora of this region by Mitten, Wilson, C. Mueller, Brotherus, and others. This is followed by an outline of the classificatory scheme used, which is, in the main, that of Dixon and Jameson’s “ Handbook of British Mosses.” Regarding the inclusion of cer- tain names the author says: “ It cannot, unfortunately, be claimed that

there are no synonyms, nor nomma nuda , in this Census., The inaccessi- bility of specimens, and even, in some cases, of descriptions, the differing principles of determination adopted by specialists, and the large number of new species of which we know nothing except the names, make an unchal- lengeable list of Australian Mosses impracticable at the present stage.”

In spite of these difficulties, nine hundred and eighteen mosses are listed, exclusive of varieties. No new species are described. The species and varieties are accompanied by notes, which are by no means bare records of places and collectors’ names. Much historical matter, discussions of the identity of doubtful species, frequent references to the original descriptions, with abundant synonomy, render these notes of great value to the student.

—53—

Such work, while showing upon the surface little evidence of the labor needed for its performance, will be of the greatest assistance to future work- ers in untangling the difficult web presented by the Australian Musci. A list of references, publications consulted, abbreviations, and a generic index add greatly to the convenience of the work. It is to be hoped that the authors may be able to complete their undertaking by issuing a list of the pleurocarpous mosses. Edward B. Chamberlain.

POGONATUM TENUE.

B. F. Bush.

While exploring a deep, moist, shady ravine on the high bluff of the Missouri river, at Sibley, Missouri, on October io, 1906, I noticed near the bottom of the ravine on the opposite side, a stratum of hard, reddish-yellow sand, which appeared to be covered at one place with a deep green scum. Jumping down in the bottom of the ravine, I was very much surprised and pleased to see that the green scum was the prothallium of Pogoncituui tenue (Menz.) Britton, which was now fruiting abundantly.

The bluff at this place is at least three hundred feet above the river, and about one thousand feet above the Gulf of Mexico, and the’ stratum of sand in the ravine is about two hundred and fifty feet below the top of the bluff.

This is the second time I have collected this species in Missouri, the other being at Pleasant Grove, Ripley County, in Southeastern Missouri, in precisely the same sort of situation on a sand stratum at about four hundred feet elevation.

The only other time I collected this species was at Spring Hill, Alabama, in a deep ravine back of the hotel, in exactly the same sort of situation, on a stratum of sand, in a, deep ravine, about two hundred feet above the Gulf of Mexico.

NOTE ON CATHARINEA ROSULATA

T. C. Frye.

An examination of type material, .that is, material collected by type col- lector at type locality and date, indicates that Catharinea rosulata (C. M. & K.) {A trichum rosulatum C. M. & K.) described in Macoun’s Catalogue of Canadian Plants, Part VI., p. 148, 1892, is simply Catharinea Selwyni (Aust.) Kindb. {A trie hum Selwyni Aust. ). The short stem ascribed to C. rosulata is often found in C, Selwyni , and in such cases the leaves are rosu- late since they cannot be well otherwise, thus agreeing with C. rosulata. The leaves in two plants agree in the undulation, dentation, areolation, form, their scales at the back, and the height and number of their lamellae. C. rosulata is said to have a leaf which is not margined, but in the material examined they are margined in their upper part where they are dentate. It agrees in this with C. Selwyni in which some of the leaves are margined to the base, others to the middle, and very young ones not at all. Thickened margins in young leaves would interfere with the normal development of the

-54-

leaf, since cells with thick walls rarely divide or enlarge. The leaves of corresponding ages in C. rosulata and C. Selwyni are margined the same. I feel sure no one could separate type C. rosulata from my authentic C. Set- wyni'xt I were to mix them. University of Washington, Seattle.

CLIMACIUM AMERICANUM IN DECORATION.

A. Bruce Jackson.

Until recently I was unaware that Climacium Americanum had any decorative value. It is, however, frequently used by English florists for wreaths and crosses, the dendroid stems being tied in bunches with a pleasing effect. The much to be regretted practice of dyeing, which is as usual resorted to, will not however commen . itself to a bryologist. A Newbury florist tells me that Climacium comes to him from the Oriental dealers in a dried condition and is called “ Resurrection Moss,” a name given I suppose because it has the property with other mosses of expanding when moistened. Two bunches of the moss colored, one olive-green and the other a hideous dark red, are before me as I write. A friend sent me two or three .years ago specimens of species obtained from the same shop, and on one of these there are two capsules, a somewhat rare condition. As five shillings is charged for a cross made up solely of this moss, its commercial value must be considerable. I am indebted to Mr. H. N. Dixon for the identification.

WEBERA SESSILIS AND ANTS.

Charles C. Plitt.

A year ago, I learned that ants were very fond of the spores of Weber a sessilis (Schmid.) Lindb. Finding a pretty specimen of this interesting little moss, I brought it home. Not being able to put specimen away as soon as I reached home, it was left over night in the vasculum ; in fact, it was several days, before I again got the time to examine the specimen. What was my surprise to find it over-run with ants ! Examining the specimen 1 found that a piece had been gnawed out of the side of nearly every one of the capsules and that the spores had been removed. Every body familiar with this moss, with its large capsules, readily sees what an especially fine inducement it offers for such a depredation.

This at once raised the question, whether such depredations ever occur in a state of nature. I was almost convinced that such do occur, but it was only recently that I found further proof that they actually do occur. On one of my trips during the early part of the present month (Oct. 1906), I came upon a pretty little patch of the Webera. Taking up a small portion of it, I saw that it was immediately over an ant’s nest, I at once examined the capsules and found them gnawed, just as I found that the ants last year had gnawed the capsules of the plants left in the vasculum.

That this moss is thus pilfered at times, seems pretty evident. It would

— 55—

be interesting to know to what extent. Is it a common occurrence, or is it only a rare one ? It would also be interesting to know, if any other mosses are likwise thus attacked. That moss spores should be an especial dainty to these little insects, is not at all improbable. Baltimore, Md.

A RED ANDRE/EA.

Cora H. Clarke.

On July 3rd, 1906, I was climbing a rocky path in the woods at Manches- ter, Mass., not far from the ocean, nor much above sea-level, when my eye was caught by the very dark red color of some small cushions of moss on a bit of outcropping rock. At least, they appeared red, or a dark red-brown, by contrast with the other mosses on the same rock. The largest cushion was but little over an inch across. Some of the cushions bore a little fruit, which I did not at first recognize to be that of Andresea; there were spores in some of the capsules.

On July 21st, a visit to this same rock showed the Andresea in a dry condi- tion, and therefore almost black. Not far off was an almost vertical rock- wall, of considerable extent, but with growths of moss here and there. Here again was Andresea but not so much in cushions as in patches with a flat sur- face. The color was not red at all but black when dry — dark green when wet —with little fruit.

Both forms answer to the description of Andrecea ruftestris , a species not new to Massachusetts since Mr. Edwin Faxon found it in Franklin Park, Bos- ton, Nov. 25th, 1886. His specimens were red rather than dark green, and showed signs of having borne abundant fruit earlier in the season.

Boston, Mass.

SULUVANT MOSS CHAPTER NOTES.

Dr. A. J. Grout, 360 Lenox Road, Brooklyn. N. Y., would like to arrange for a Sullivant Moss Chapter exploration of Mt. Washington, N. H., some time during next July. Those interested please address as above.

Miss Lydia Prichett Borden, Manoa, Pa., under date Jan. n, 1907, writes that she found Mnium spinulosum B. & S. in full fruit and many plants with the spores apparently perfectly ripe on January 1st, this year. A friend also found M. sylvaticum in fruit and a few other species which usually fruit in spring. These were all found in Delaware County within a few miles of Philadelphia.

Since March 1st the following persons have qualified as Chapter mem- bers: No. 174. Dr. Marshall A. Howe, New York Botanical Garden, Bronx

Park, New York City. No. 175. Mrs. L. E, C. Rohrabacher, Hotel Stan- der, Seattle, Wash. No. 176. Rev. C. H. Waddell, The Vicarage, Saint- field, Co. Down, Ireland. No. 177. Dr. I. Hagen, Natural History Museum, Trondhjem, Norway, No. 178. Dr. V. F. Brotherus, Helsingfors, Finland, Sweden.

In opening a new set of books it has been found advisable to send out all

FURTHER NOTES ON CLADON1AS. XI.

Cladonia pyxidata and Cladonia pityrea.

Bruce Fink.

Cladonia pyxidata is perhaps as easy to distinguish as any of our Cla- donias, but it is sometimes confused with forms of Cladonia fimbriata , espe- cially C. fimbriata shnplex, which has rather short podetia and large cups for ihe species. Some of our best workers in American lichenology have also confused Cladonia pyxidata with immature and sterile specimens of Cla- donia deformis. This species could likewise be confused easily with the northern alpine Cladonia carneola.

Cladonia pityrea is little known in America, and the writer can only state his own difficulties with the species. Of the forms submitted to Dr. Wainio, he had supposed the one from Iowa to be an unusual condition of Cladonia cristatella, two of those from Minnesota had been doubtfully referred to Cladonia fimbriata , and the others were recognized as very unusual Cladonias"and sent without attempt at determination.

After a careful study of the effects of KOH on the thalli of Cladonias, the writer is convinced that in many instances these chemical tests are of considerable supplementary value in spite of differences due to age of thalli, differences in substrata, etc. However, in all of the species mentioned above, the KOH test is always or most usually negative or nearly so, so that its use in diagnosis, would be of very little or no value. In a supplementary paper, at the close_of this series, the writer will give the results of his studies with KOH so that they may be used to supplement the diagnoses.

The specimen of Cladonia pyxidata that furnishes the illustration for this paper was collected by the writer at Tower, Minnesota, and determined by Dr. Wainio. That for Cladonia pityrea was collected near Hofheim, Ger- many, by L. Scriba, and determined by him as follows: “ Cladonia pityrea

(Flk.) Fr. inter 5. cladomorpham Floerk. et 6. hololepidem (Flk.) Wainio.”

Cladonia pyxidata (L.) Hoffm. Deutschl. FI. 121. 1796. Primary th al- ius commonly persistent, composed of irregularly or digitately incised or lobate, flat, concave or rarely convex, commonly ascending, clustered or scat- tered squamules, which are 2-8 mm. long and 1.5-6 mm. wide, sea-green above or varying toward whitish or olivaceous, commonly lighter and sore- diate below. Podetia arising from the surface of the primary thallus, 3.5-30 mm. long and 3-4.5 mm. in diameter; turbinate or tubaeform, erect; the cortex areolate, or verrucose, or subcontinuous toward the base; frequently more or less decorticate toward the top, rarely more or less squam- ulose; sea-green varying toward ashy or olivaceous: the decorticate portion white or ashy-brown: frequently closely clustered; cup-bearing. Cups 1-7 mm. in diameter, regular or irregular; on well developed podetia or the dila-

tion beginning just above the primary thallus: the cavity non -perforate and wholly or partly corticate: entire, dentate or proliferate from the margin, the proliferations one or more ; the ranks 1-3. Apothecia medium sized, 1-4 mm. in diameter; solitary or conglomerate; regular or irregular: sessile on the margins of the cups or on longer or shorter pedicels: flat and thinly margined or more commonly convex and immarginate: commonly brown and ours all some shade of brown: scarcely common. Hypothecium pale or pale-brown- ish. Hymenium pale or pale-brownish below and brownish above. Para- physes simple or rarely branched, commonly thickened and brownish toward the apex. Asci clavate. Plate VII. Fig. 1.

1 On earth or rocks, or rarely on old wood, usually in places only moder- ately moist and shaded. Examined by the writer from New Hampshire (G. K. Merrill and R. H. Howe, Jr.), Massachusetts (H. Willey), Maine (Clara E. Cummings and G. K. Merrill), Long Island (H. von Schrenk), New York (Carolyn W. Harris and E. A. Burt), Ohio (E. E. Bogue and M. Foltz), North Carolina (H. A. Green and determined as Cladonia turgida ), Louisiana (A. B. Langlois), Missouri (Colton Russell), Minnesota, Iowa, Ohio, Washing- ton and Alberta (Bruce Fink), Kansas (H. Willey), Nebraska (T. A. Williams), Colorado (C. F. Baker and H. H. Butler), Wyoming (Aven Nelson), Montana (R. S. Williams, L. H. Pammel and M. J. Elrod), New Mexico (F. S. Earle), Newfoundland (A. C. Waghorne), Alaska (Wm. Trelease), California (H. E. Hasse). Listed from Alabama by C. Mohr and from many localities in British America by J. Macoun. But Mr. Macoun has not recognized the first variety below, and doubtless some of his material belongs there. Willey and Cal- kins both list from Illinois, and Eckfeldt and Calkins from Florida. Wainio adds nothing to the general North American distribution given above.

The plants listed above are those which Dr. Wainio would place for the most part under Cladonia pyxidata neglecta, simply calling certain poorly developed forms by the specific name only. So far as examined by the writer the great majority of all specimens belong here, and this form should stand for the species.

Cladonia pyxidata chlorophaea (Spreng.) Flk. Clad. Com 70. 1828. The podetia more or less decorticate and sorediate toward the top.

Examined by the writer from Maine (G. K. Merrill), Massachusetts (R. H. Howe, Jr.), New York (Carolyn W. Harris), Iowa, Minnesota, Washington and Ohio (Bruce Fink), Tennessee (W. W. Calkins), Montana (M. J. Elrod), Colorado (C. F. Baker and L. H. Pammel). Newfoundland (A. G. Waghorne). Also listed from California by H. E. Hasse. Dr. Wainio's distribution adds Great Bear Lake, Miquelon Island and Pennsylvania. No doubt generally distributed over North America, but by no means so abundant as the species. Known in all the grand divisions.

Cladonia pyxidata pocillum (Ach.) Wainio. Mon. Clad. Univ. 2:241, 1894. Primary thallus of rather large and thick, round-lobed or somewhat incised, closely adnate or slightly ascending squamules, which are more or less imbri- cated and closely packed into a commonly olivaceous or brownish crust. Podetia partly decorticate above, but not sorediate. Examined by the writer

-59-

from Minnesota and Alberta (Bruce Fink), W. W. Calkins lists from Illinois, T. A. Williams lists as common at Rapid City, South Dakota, H. Willey has listed from Massachusetts, H. E. Hasse from California, and J. W. Eckfeldt and W. W. Calkins from Florida. John Macoun gives several localities in British America, and Wainio's distribution indicated that the plant is con- fined almost exclusively to arctic or alpine regions. In view of this, the dis tribution in the United States, as given by American workers in recent years, may well be considered' with careful re-examination o£ material. Found in Europe, Asia and Africa.

Primary thallus finally disappearing, when present composed of subdigitate, laciniate or crenate, involute concave or flat, ascending, clustered or scattered squamules, which are 1-3 mm. long and 0.5-2 mm. wide, sea-green or olivaceous above and white below and rarely more or less sorediate-granulose. Podetia aris- ing from the surface of the primary thallus, 3.5-50 mm. long and 0.5-4 mm. in diameter, tubaeform, turbinate or subcylindrical; scattered or clustered into- small patches: usually erect; the cortex subcontinuous and verrucose, or com- posed of small areoles, the areoles raised and contiguous, or the surface almost entirely decorticate and frequently sorediate-granulate; sometimes, more or less squamulose; sea-green varying toward ashy or olivaceous, the^ decorticate portions commonly white, sometimes cup-bearing, the cupless, and sterile apices obtuse or subulate, simple or digitately or irregularly- branched. Cups 0.5-3 mm. in diameter, gradually or abruptly dilated, com- monly more or less irregular, often oblique, the cavity rather shallow; the margin dentate, lacerate or proliferate, the proliferations one or more and the ranks 1-3. Apothecia small or medium sized, 0.5-4. 5 mm. in diameter, often conglomerate; usually on short pedicels on the margins of the cups or at the cupless apices: the disk flat and thinly margined or becoming convex and immarginate; commonly brick-red (but ours are more commonly a dark brown). Hypothecium pale or pale brownish. Hymenium of same color or darker brownish above. Paraphyses simple or branched, commonly thick- ened and brownish toward the apex. Asci clavate or eylindrico-clavate. Plate VII. Fig. 2.

The only American specimens examined by the writer are a half dozen specimens submitted by him to Dr. Wainio, five from Minnesota and one from Iowa. Of the six, four were referred by Dr. Wainio to some of the various forms which he recognizes, and two, one from Iowa and one from Minnesota, were returned marked simply Cladonia pityrea. Dr. Wainio recognizes the species from Vancouver Island, Oregon, Massachusetts, South Carolina, Cuba, Porto Rico, Mexico, and one or two other small islands. This would give the plant a wide North American distribution, though it does not seem to be recognized by American lichenists, except those plants determined for the writer by Dr. Wainio. The species is doubtless a compound conception, but we can do no better, in the present state of knowledge, than to simply record below the three forms which Dr. Wainio has been able to recognize in the specimens sent him by the writer. While this treatment is far from sat-

— 6o —

isfactory, it is hoped that it will enable American workers to recognize the species and perhaps the forms given below. For other forms that are per- haps quite as likely to occur with us, the reader is referred to Dr. Wainio’ s Monograph.

Cladonia pityrea phyllophora (Mudd. ) Wainio Mon. Clad. Univ. 2: 355, 1894. Podetia cupless, only 10-30 mm. in length, more or less squamulose, corticate and without soredia. But Dr. Wainio admitted here one of our forms, more or less decorticate. Specimens collected at Emo, on the north- ern boundary of Minnesota and on Oak Island, in the Lake of the Woods, were placed here by Dr. Wainio. Elsewhere recognized only in Europe.

Cladonia pityrea subacuta Wainio Mon. Clad. Univ. 2: 355, 1894. Podetia cupless, 10-35 mm. in length, wholly granulose, or verrueose or areolate-corticate toward the base, almost devoid of squamules.

A single specimen from Emo was placed here by Dr. Wainio. Not known elsewhere from North America. More or less common in Europe.

Cladonia pityrea cladomor°pha (Flk.) Wainio Mon. Clad. Univ. 2: 255,1894. Podetia cup-bearing, the ranks quite short (about 12 mm.), granulose or sore- diate, often verrueose or areolate-eorticate toward the base, devoid or almost devoid of squamules.

The great similarity of the last two varieties or forms is apparent enough from the descriptions, and Dr. Wainio referred the cupless podetia -of the collection from Emo to the last variety above, and those having cups to the present one. The taxonomic value of such forms may be doubted, but we record them, leaving the future to decide as to their value. A speci- men collected in California by Dr. Given (1869) and sent to the writer as Cladonia pyxidata was referred to the present form by Dr. Wainio. Except for these two forms submitted to Dr. Wainio, not recognized in America. .Several European exsiccati have been placed here.

NOTES ON RECENT LITERATURE II Notes on the Physiology of the Sporophyte of Funaria and Mnium.

A. J. Grout.

(R. H. True in Beihefte Bot. Centralblatt IP1: 34-44, 1905.)

This is an account of interesting experiments to discover the exciting cause of curvature of the seta in Funaria hygrometrica and Mnium cuspida- tum Hedw. Dr. True concludes that “The young sporophyte, prior to the development of a distinct capsular rudiment, is either positively heliotropic or negatively geotropic, and tends to assume a perpendicular position which is fixed by the further development of the tissues. When in the young sporophyte the capsular rudiment has begun to develop, a sharp curvature appears just below the capsule, turning the capsular rudiment into the per- pendicular position of either a positively geotropic or of a negatively helio- tropic reaction.”

Further experiments “seem to make it clear that in the case of Mnium ,

-6i —

and probably of Funaria also, the 1 nodding ’ of the capsules is brought about by the stimulating action of gravity, since the direction of the illumina- tion does not interfere with the tendency of the capsules to assume the • nodding,’ or in the case of Mnium, the pendulous position seen in nature.” “The directive influence of illumination is clearly marked in determining the plane in which the capsular rudiment shall fall. Sometimes the apex of the capsule falls toward the light, sometimes from it.”

“In an early growing stage the young sporophytes seem to react some- what to gravity in a negative sense, tending to bend upward toward the per- pendicular whether lighted from above or below.”

The following were incidental observations in connection with the experi- ments. The entire zone of elongation of the sporophyte (in Funaria ) is situ- ated inside the calyptra. The zone of elongation is limited to a space within 2 mm. from the apex, the most rapid growth being found about 0.8 mm. from the tip. “ The young seta was found to have reached its complete diameter at any given point as soon as its growth in length was completed,”

The calyptra appears to serve a very important purpose in preventing the drying up of the young sporophyte tip. In Fu7iaria, because of the more dry and exposed habitat of the species, it is only after the capsules are half grown that they are able to survive the drying out of a few days of hot dry weather. “ Hence the season for sporophyte formation falls in the moist season of the year when the temperature is sufficient to allow rapid growth.’’ In Funaria the young calyptra consists of a long beak-like distal portion, an enlarged sac-like portion contracted at base into a short collar-like portion which clasps the seta very tightly. Although this sac-like calyptra be removed with extreme care the sporophyte will not develop unless the cap- sules be half grown. Dr. True infers that this is due largely, if not entirely, to the drying out of the fcapsule after the removal of the calyptra. The cells of the calyptra have abundant chloroplasts, and Dr. True believes that it has powers of independent nutrition, but is somewhat in doubt as to the source of its water supply, which is apparently the minute quantity of Water usually to be seen in the upper part of the calyptra during the earlier stages of sporophyte development. As Mnium cuspidatu?n grows in moist situations its calyptra can be, and is, spared much earlier. Brooklyn, N. Y.

DO YOU WANT YOUR POLYTRICHACEAE IDENTIFIED?

In the course of some work on the Polytrichaceae of western North America, to be published later, the writer has had occasion to attempt the elaboration of serviceable keys to the species of the family. To test these keys, and to get a wider acquaintance with the variations in the group the writer would be pleaSbd to receive for determination, verification, or simply for examination, collections of Polytrichaceae, including the genera Cathari- nea (Atrichum), Oligotrichum, Bartramiopsis, Polytrichadelphus, Pogona- tum, Polytrichum.

Pretty small species, remarkable by its perichaetial leaves much larger than the stem leaves, its very small capsule, its seta nearly equal to the cap- sule and consequently more developed than in most species of the subgenus Sckistidium.

It resembles by some characters the Grimmia atricha Kdb., from which it is easily distinguished by its revoluted leaves, its smaller capsule, its longer seta and its peristome with red teeth.

THE VALIDITY OF SOME SPECIES OF FISSIDENS.

E. J. Hill.

Among the species of Fissidens which I have observed in the prosecu- tion of field work none have had so varied a treatment as the following: F

— 68 —

exiguns Sulliv. For comparison with these there have been furnished from the Herbarium of Columbia College, New York City, F. inconstans Schimp- Cheyenne Canon, Colorado, 1872; F.

Ital.; F. bryoides Hedw. from near Durlach, Baden; F. bryoides var. inter- medius Ruthe=var. gymnandrus Buse. (No. 1160 of Rabenhorst, Bry. Eur. , collected by R. Ruthe, locality not given. This No. 1160 Warnstorf in Kryp. FI. Mark Brand. Laubmoose 2: 171, 1906, gives as F. impar Mitt.). From the Sullivant Herbarium at Cambridge, Mass., F synoicus Sulliv. San Marcos, Texas, Ch.

Vogesengebiet am feuchten Waldenorten, P. Reinsch, Nos. 84986 and 116238; F exiguus Sulliv. Ex, Musci Allegh No. 84199. The other specimens used are of my own collection, the oldest F. minutulus Sulliv. Kankakee, Illinois, 1872, determined for me by the late Thomas P. James This has been the species most frequently found since, and occurs in exam- ples from Minnesota, Illinois and New York. All my other examples, F. exiguus , F. inconstans , F. synoicus , F. incurvus Stark, 1807 (=F. incur- vus Schwaegr. 1816), are from northern Illinois.

F. inconstans in the Manual of Lesquereux and James seems to be lim- ited to the collection of Wright at San Marcos, Texas. It is the only exam- ple cited, and F. synoicus Sulliv. is made a synonym. No reference is made to its presence elsewhere as is usual in the case of rare species. The Colo- rado specimens were collected by T. C. Porter, July 11, 1872. They are labeled “A! inconstans Schimp., Ed. n ( F . bryoides var. inconstans Limpr- Laubmoose).” Why it was not referred to in the Manual published in 1884’ is not evident. It may have been due to the uncertainty of its standing in the opinion of one of the authors, Mr. James, or have been overlooked. The following note of his (fide Mrs. Britton) accompanies the specimens: “A.

Porteri n. sp. provisional. Stems branched, the branch bearing the fruit- stalk is attached to the main stem about one-fourth its length. The capsule small, oval, almost rotund. The male organs are axillary on the main stem (Monoecious). Can it be a hybrid between F. incurvus and F. bryoidesl A Fissidens which I cannot specifically separate from this I have twice found at a single station at Glenwood, 111.

Fissidens inconstans was described by Schimper in 1876 from specimens found by H. Boswell near Oxford, England, in 1863 (Synop. Mus. Europ. Ed- 11, 1 14, 1876.). Its fruit is said to mature in March. Schimper states that it is very inconstant in the position of its fruit, which is sometimes terminal, sometimes lateral and axillary, the capsule smaller than in F. incurvus , “ always suberect or erect.” “ Whether a species near to the very polymor- phic F. inctirvus is really distinct or not is doubtful,” he adds. Warnstorf, one of the latest authorities, gives it specific rank, grouping it in his Ueber-

C., 1874, to which the article on Musci was contributedby Leo Lesquereux, no species of Fissidens is given The list includes, among new ones described, those col- lected by Porter and others in 1872 and 1873.

sicht der Arten with F. bryoides (L.) Hedw. and F gymnandrus Buse, of which he makes a species also. It is marked by an asterisk as not yet found but likely to occur within the area his work embraces, and consequently is not fully described. (Kryp. Flora der Mark Brand. Laubmoose 2: 166, 1906.) This rank I take to be given it also by the way it is labeled in the Herbarium of Columbia College. Roth makes it a variety of F bryoides , as also Lim- pricht; Husnot a variety of F. incurvus\ Boulay one of cycle of forms, including incur v us, eras sipes, pitsillus and Bambergeri , all closely allied to F. incurvus. Dixon considers it a form or sport of F. bryoides\ Barnes both this and F. synoicus sports of F. incurvus. (A Revision of North American Species of Fissidens, Bot. Gaz. 12: 31, 1887.) Here are three main conclu- sions, (a) a species, (b) a variety, form or sport of F bryoides , (c) a variety or sport of F. incurvus.

Since I did not obtain specimens of F. inconstans from any European locality, the statements in this paper so far as based on examination of plants refer to the collections from Colorado and Glenwood, There is the possibil- ity that they may not be the equivalents of the European moss, though this seems probable. From the provisional name proposed by James he had his doubts. The plants at Glenwood were first collected October 24, 1899. Hav- ing found the synoicous plants in a packet of Gymnostomum calcareum obtained at Lockport, 111., June 29, 1905, but examined some months later, I again visited the Glenwood station April 12, 1906, and fortunately found mature plants, since the first collections were all immature. They were in full fruit, the opercula mostly gone, the capsules frequently injured or broken off from rough usage in the winter. They showed a moss fruiting in the cold season of the year, quite in contrast with the synoicous form from Lockport, not so far advanced the last of June. They were associated with F. cris- t'atus , Dicranella heteroilialla , Mnium cuspidatum and a species of Anomo- don. A full description of the Glenwood and the Colorado specimen is given below, illustrated by a drawing of plant, leaf, and its terminal portion from the Glenwood specimens, Plate IX. Figs. 8-10.

Fissidens synoicus (n. sp.) — Hermaphrodite; stems simple, inclined, 3"-6" long; leaves 12-14 (pairs ?), oblong-lanceolate, oblique, shortly acuminate, bordered except at the denticulate apex, the blade shorter than the duplicature, the dorsal wing vanishing above the base: costa continuous; capsule terminal, oval-oblong, erect: operculum rather long-rostrate. San Marcos, Texas. Wright. — A small species, distinct by its whitish green leaves with a close areolation, regular erect capsule, and hermaphrodite inflorescence.”

Prof. W. G. Farlow writes me that the bnly writing on the specimen in Herb. Sulliv. is that given above where the specimen is cited. As seen by the direction given in the separate it was to be placed between F. exiguus and F. ?ninutulus, which in the Manual are immediately followed by F. bryoides, thus indicating its relative position. I append a fuller description, based on the collection from Lockport, which I identify with those from San Marcos, and on those in the Herb. Sulliv. It is illustrated by Plate IX. Figs. 1-7 and Fig. ii. These are made from the Lockport moss.

Fissidens synoicus Sulliv. Cespitose, stems mostly simple, erect or inclined at base, 6-12 mm. high. Leaves pale green, 8-20 pairs (mostly 10-15 pairs), oblong-lanceolate to linear-lanceolate, short acuminate or acute and apiculate, 11-1.8 X 0.3-0.45 mm., the lower shorter: erose denticulate near the point, somewhat wavy-sinuolate below; costa subpercurrent, occa- sionally forming the point. Border 1-3 cells wide, or on vaginant lamina four cells, frequently indistinct or absent, especially on one side, usually ceas-

ing below the point and on the very narrow base of the dorsal lamella. Vag- inant lamina rather more than halE the length of the leaf-complex. Cells of middle and upper part roundish hexagonal to polygonal, 6-11/4 in diameter, often quite variable: basal celis rather hyaline, quadrangular, some nearly square, 13-27 X 6-10/*. Synoicous or dioicous, the flowers terminal or some- times in a bud near the base. Antheridia 1-5 (1-7) large, subclavate, the slender archegonia more numerous, sometimes 18-20, without paraphyses. Seta reddish, 3-4 mm. long. Capsule erect, green, oval-oblong to subcylin- drical, o. 5-0.7 mm. long, the mouth purplish. Operculum conic-rostrate, long-beaked, the length of the capsule, straight or slightly oblique,

brownish. Teeth russet-brown, broad, rather short, not deeply divided smooth or little papillose, the broad cross-bars horizontal. Spores globu- lar, green, pitted, 13-16/4 in diameter.

Moist and shaded calcareous rocks. Fraction Run (now Dellwood Park) Lockport, 111., June, 1905, E. J. Hill; San Marcos, Texas, Charles Wright, 1847. At Lockport it is associated with Gymnostomum calcareum Br. Germ and A mblystegium varium (Hedw.) Lindb.

The chief difference between F. inconstans and F. synoicus is in the inflorescence and the time of maturing the spores, winter or early spring in one, early, or midsummer in the other. This would of itself suffice to' differ- entiate them specifically. The teeth of the former are slender and quite long, divided below the middle, the parts very papillose and spirally thick- ened. In F. synoicus the teeth are not deeply divided, smooth or smoothish the parts not spirally thickened. In F. inconstans the thickened leaf-border is generally confluent with the costa at the point and readily separates from the cells of the body of the leaf; in F synoicus the border is less developed or more interrupted, not thickened or cord-like, and usually ceases below the point. Its spores are green and pitted, those of F. inconstans are yellow or brownish yellow.

In its inflorescence F synoicus is nearest to F. Bambergeri. Schimper described this as dioicous, (Syn. Ed. 11, p. 115). Roth, Boulay, Husnot and Milde give it variously as polygamous, synoicous, dioicous. I have found it both synoicous and dioicous. Of twelve stems examined eight had floral organs, two of them synoicous, two had archegonia only, four antheridia or with buds having the short leaves of the perigonial form. In synoicous flow- ers the leaves were the larger, perichaetial form, with 2-5 archegonia and one or more but few large antheridia, all kinds without paraphyses, or rarely with some. In the case of stems without fruit my experience is similar to that of Milde, who says: “I always found the fruiting plants without male flowers. The plant is also dioicous. The sterile plants bear either a single female terminal flower, which consists of 5-12 archegonia without para- physes, or a single terminal hermaphrodite flower in which I found r-3 antheridia and 3-5 archegonia without paraphyses. Since the antheridia were always very large an error is not possible. The archegonia on the other hand were always very long and slender.” (Zur Kryp. Flora sud. Tirol. Bot Zeit. 22: 12, 1864.) Milde considers it similar to F. incurvus : Schimper as

— 72—

nearest F '. minutulus , its time of fruiting “early spring.” Roth says “late autumn and winter.” In this character it is allied to F. bryoides, inconstans and incurvus.

F B amber geri is in almost all respects smaller than F synoicus. The stems are 1-3 mm. high, with 4-12 pairs of leaves, those of the middle part of the stem, 0.6-0. 8 X 0.2-0.27 mm., the cells 4-8/* in diameter. The seta is relatively long, 2.5-5 mm., the pale capsule 0.4-0.6 mm., the yellow* brown spores 12-15^. The teeth are split about their length, slightly papillose, the parts spirally thickened. The leaves are rather obscurely mar- gined, generally by a single row of cells often broken or interrupted, absent from some part or wholly gone. When absent the margin becomes a row of quadrate, nearly square pellucid cells similar to the margin of the leaves of F exiguus. The habitat of F. Bambergeri in Tirol is given by Roth as “sandy loam in little hollows of rocks on hot slopes,” thus pointing to a xerophytic nature, while F synoicus at Lockport is mesophytic.

F. synoicus should also be compared with F. incurvus. The inflores- cence of this is autoicous, the antheridia terminal on short branches near the base of the fertile stems. The sharp pointed leaves are not bordered quite to the denticulate apex, the costa ceases just below the point, or becomes pro- tuberant in the upper leaves. The border of the vaginant lamina is quite characteristic. It is 4-5 cells wide, but ceases properly somewhat above the base, gradually merging in the long quadrangular or polygonal cells of the leaf base. The teeth are quite long and slender, rather deeply divided, resembling those of F. minutulus. They are very papillose, the trabeculae prominent, the parts spirally thickened above the middle. The capsule of F. incurvus is not always curved, it may be erect as in F synoicus. I find it thus in a collection made at Savanna, 111. The two collections of P. Reinsch cited above differ from each other in this respect. Both have the same kind of habitat, moist places in the forests of the Vosges'. One collection has the typical curved or horizontal capsule, the other the erect. All three have the same structure of leaf cells, the latter 8-15/bin diameter, the average 11 or 12//.*

The other species to be considered are F. exiguus and F. minutulus. They were described and figured by Sullivant in 1846. (Mem. Am. Acad. N. Ser. 3: 58-60. T. 2, 1846 Also Icon. Mus. Part 1, 36, 37, T. 23, 24, 1864.) As such they were retained in Gray's Manual and so appear in that of Lesquereux and James. Austin made them varieties of F. incurvus. Barnes and Grout made the same disposition of them, but the latter with a reserva- tion that the later maturing of the spores in August rather indicates a speci- fic rank By European bryologists one or both have been regarded as species or been considered the equivalent of other species or varieties. Thus both have been referred to F. pusillus Wils., and F. .exiguus to F. viridulus Wahl. F minutulus has been made F. pusillus var. madius Spruce, F.

*The name F. synoicus n. sp. appears a second time in bryological literature, having been used by C. Muller for a species collected in Argentina, South America, in 1873, and published in Linnaea, 42: 240, 1878, 1879. From the reading of the description I hardly take it to be the same as Sullivant’s moss If not a homonym of F. synoicus Sulliv . (1856), it is invalidated by priority, and the one from Argentina should be given another name if on comparison it is found to be distinct.

—73—

exiguus the same as F pusillus var. Lylei Wils , or F viridulus var. Lylei (Wils.) Dixon.' This reference to at least three species and two vari- eties, along with specific rank besides, shows much diversity of opinion, and that it may be less confusing to leave them as Sullivant had them.

Both are quite similar in habitat, the most common the dry channels of brooks and rills as I have seen them. F. minntulus I have also collected on stones in damp places of woods or on ledges of rock by larger streams. The desiccated condition of the more common habitat favors their fruiting in mid- summer, since the stream beds are without running water, though it may remain in pools; the localities are therefore moist and commonly shaded. F. minutulus is apt to adhere very closely to a rock substratum. There maybe no more appearance of a soil beneath it other than of the disintegrated rock than in somecrustaceous lichens, or some species of Orthotrichum and Grim- mia. There seems to be no choice of mineral constituents, for the stones and pebbles are of the various kinds washed from the drift in which the channels are cut. When on ledges they have been calcareous, which may be because the localities commonly accessible to me are of limestone formation. It is also apt to be unassociated with other mosses. F. exiguus I have found associated on clay with Amb ly ste gium v arium .

Both species are dioicous, the male flowers mostly on shorter plants, which are sometimes little more than buds provided with rhizoids and con- cealed in the rhizoids of the larger fertile or sterile stems. In this they dif- fer from F. incurvus, of which they have been made a variety, and which is described by most authors as autoicous, though Roth makes it dioicous. Warnstorf gives it as both dioicous and autoicous. They may be deceptive in this respeet. The male flowers on the short basal branches may be well furnished with rhizoids and easily detached by the slightest force. When this happens accidently pr spontaneously the male flowers will appear as lit- tle stems among the rhizoids of the fertile plants, as in the case of F niinu- .tulus. When well advanced in growth there is apparently no vital connection with the parent plants even when remaining in place. From this experience with them I have been led to infer that the male organs may start as buds in the axils of leaves of fertile stems and become independent actually or appar- ently, or show a pseudo-dioicous inflorescence, which may account for some of the discrepancies.

The principal distinction between F minutulus and F exiguus has been found in the character of the leaf-margin. It is called immarginate in the latter; I have not found this quite exact. There are two types of border in Fissidens, one of linear cells that may be cord-like and not always firmly united to the cells of the body of the leaf. F. bryoides is one of the best examples. With it are classed minutulus , incurvus and inconstans. The other type has a row or band of cells less or but slightly chlorophyllose and consequently less deeply colored and more translucent than the remaining cells of the leaf, or they may be differently colored with some tinge as of yel- low. They are also in general more uniform in size and shape. This kind of margin varies from a single row of cells to a band or zone four or five cells wide. The wide yellowish form is seen in F cristatus and F cidiantoides ;

while in F. ta^ifolius and F. osmundoides it is of less thickened cells and but one or two cells wide. F exiguus can be placed in this class though not always so closely and uniformly defined. It has a marginal row of ceils lighter and more pellucid as well as more nearly square or less irregular than the remaining leaf-cells. I had made a note of this when first finding the species several years ago, and have used it since as a help in distinguishing the two closely allied species. It is just as apparent in the example from the Musci Alleghanienses. In the drawing of the leaf F exigmts in Sullivant’s leones Muscorum, PI. 23, Fig. 9, this feature is not clearly brought out, and the margin does not differ essentially from the remaining cells of the leaf, only slightly more uniform perhaps. The squarish and more uniform size of the marginal row is more apparent in the plate accompanying the original descrip- tion in the Memoirs of the American Academy, n. ser. iii, Tab. 11, B Fig. 2, though as Sullivant viewed it, it was with “ foliis im margin atis,” as com- pared with the “ lamina limbata ” of F minutulus figured on the same plate. Leaves with a border row of pellucid cells of this character, whether called immarginate or marginate. are readily distinguished from those with the margin of F. m in utulus. As remarked above on the leaf of F. Bambergeri , where the border with the linear type of cells was absent, there was an appearance of the other type.

Comparing the two in other respects the leaves of F. exiguus are more shortly and abruptly pointed, maintaining their width more fully to near the apex, making a shortly acuminate or acute leaf. Its capsule is commonly thicker in proportion to its length, 'the operculum with a shorter and stouter beak. In both the teeth are very papillose but in minutulus they are exceed- ingly long and slender, more so than in any considered in this paper, and so deeply cleft that one or both parts, though apt to be unequal, may be four times the length of the basal portion. In exiguus they are about twice the length, appearing less deeply divided though the basal part may be as broad as in minutulus. The trabeculae in F. minutulus are mainly horizontal but vary to oblique : or the projections may even take the spiral and somewhat thickened forms, the latter features quite exceptional as I have found them. In F. exiguus the spirally thickened form becomes more obvious, but as it is an inconstant character in both its value is not great in distinguishing them from each other, though on account of its quite uniform presence in bryoides , inconstans and incur vus, it is useful in separating the two from these.

In conclusion I wish to acknowledge my indebtedness to Mrs. Agnes Chase, of Washington, D. C., for the drawings and for copies of descriptions, and to Mrs. Elizabeth G. Britton and Prof. W. G. Farlow for the gift or loan of specimens. Chicago, 111.

CATHARINEA CRISPA IN MAINE.

Alice L. Crockett.

It is a pleasure to announce the discovery of a station for Catharinea crisfici James, in Maine, it not having been reported before from this State, nor so far northeasterly as this. It was found in fruit in Camden, Maine, 44° N. lat. 69° W. long., in a pasture near the bank of a large brook, on knolls where six years ago a growth of alders had been cleared away. The altitude is about 200 feet. For its determination I am indebted to Mr. E. B. Chamberlain. Prof. J. Franklin Collins, in his list of New England plants, Rhodora 8: 13 1, 1906, gives only Massachusetts as definitely possessing it. See also Rhodora 9: 74, 1907. Camden, Maine.

POLYTRICHUM GRACILE IN HAINE.

Elizabeth Marie Dunham.

Among the mosses collected in September at Middle Dam, Rangeley Lakes, Maine, there was one strange Polytrichum which Prof. J. Franklin Collins has determined Polytrichum gracile Dicks, and he speaks of it as a form with low lamellae and wide leaf margins. (Fig. a.) This variation is noted in fine print after the description of the species in Dixon and Jameson’s “ Hand-book of British Mosses.” In comparison with a specimen (Fig. b.) collected by Mrs. Annie Morrill Smith in the Adirondack Mts., the Maine specimen shows leaf margins about three times wider, and the lamellae only three cells high instead of four or five as in the New York specimen. There was only one small patch of the moss, growing on the ground in a woody swamp. Upon first examination wTith hand lens, the leaves closely resembled Catharinea augustata , although the growth as a whole was plainly that of a Polytrichum. It is the first record of its occur- rence in Maine, as far as Prof. Collins can learn. Auburndale, Mass.

SULLIVANT MOSS CHAPTER NOTES.

We record with sorrow the death on Monday evening, June 3d (1907), at his home at Clayville, Oneida Co., New York, of Mr. Benjamin Davis Gil- bert. He suffered not long ago a paralytic stroke, and has since been in feeble health so that his death was not entirely unexpected. As a young man Mr. Gilbert took up the study of botany, giving attention especially to the ferns and later to cryptogams. In his death the Chapter loses a devoted friend.

We have received from Burroughs Wellcome & Co., a copy of “Well- come’s Photographic Exposure Record and Diary” for 1907 (United States Edition), and on reading it can do no less than advise our readers to send for a copy. Address as above, 45 Lafayette street, New York City, enclosing fifty-cents. We intend to use the “Exposure Calculator” and other rules, etc., during this summer, aud will report later on our success.

Owing to illness Miss C. C. Haynes has been obliged to delay her series on Lophozia species, but we hope to publish the conclusion in the Septem- ber number. This also explains her failure to answer correspondence more promptly.

FURTHER NOTES ON CLADONIAS. XII.

Cladonia baciUaris, Cladonia macilerata and Cladonia didyma.

Bruce Fink.

With this number of the series we pass from the brown fruited Cladonias to those commonly having scarlet apothecia. Of the three considered in this paper, the first two are so closely related as to render their separation most difficult and uncertain. The difficulties to be encountered are discussed at length under the description of the second species. The third of the three lich- ens is closely related to the other two, but the character of the squamules, especially the minute ones of the podetia when present, usually will serve to differentiate sufficiently. Tuckerman has referred to this plant as “ Not a little resembling C. bellidifiora in miniature,” but none of the specimens known to the writer need be mistaken for this species.

All three of the plants considered resemble Cladonia cristatella in gen- eral form, but that species has the podetia uniformly corticate.

To illustrate the first two species, we have chosen for Cladonia bacil- laris a specimen from northern Minnesota, and for Cladonia macilenta one of L. Scriba’s plants, collected in Germany.

Cladonia bacillaris (Del.) Nyl. Lich. Lapp. Cr. 179. 1866. Primary thallus persistent or finally dying, composed of laciniate, lobate or crenate squamules, which are 1-3 mm. long, and about 1 mm. wide, flat or somewhat involute, scattered or clustered, sea-green or varying toward whitish or olivaceous above, and wholly white below or darker toward the base of the squamules, sometimes sorediate along the margin and below. Podetia aris- ing from the surface of the squamules: quite slender, subcylindrical, rarely enlarged toward the apex; 5-55 mm. long and 0.5-2 mm. in diameter or even 4 mm. at the apex; cupless or rarely with very poorly developed cups; simple or rarely branched: often sterile and the apex obtuse or rarely subulate, or terminated by imperforate clustered or solitary apothecia; erect, the greater part or entirely sorediate, sometimes squamulose toward the base, and the squamules frequently occurring half way up or rarely even to the top, often corticate toward the base and below the apothecia, ashy, sea- green or olivaceous or a mixture of these colors. Apothecia medium sized, 1-5 mm. in diameter, solitary or clustered, immarginate or rarely margined, usually convex, scarlet. Hypothecium pale. Hymenium reddish toward the top and paler toward the lower part. Paraphyses simple or branched toward the thickened and reddish apex. Asci cylindrico-clavate. Spores obliquely disposed. Plate X. Figs, ia and ib.

On earth, old logs or stumps, found usually in rather open and dry places.

The July Bryologist was issued July 3, 1907.

Examined by the writer from New Hampshire (R. H. Howe, Jr.), Illi- nois (C. P. Clinton, for whom determined originally by the writer as Cla- donia macilenta ), Iowa, Minnesota and Washington (Bruce Fink), Tennessee (W. W. Calkins, who determined as Cladonia macilenta). New York (Caro- lyn W. Harris), Mexico (J. G. Smith and named Cladonia mitrnla by T. A. Williams), Newfoundland (A. C. Waghorne and called Cladonia macilenta by Dr. F. Arnold). H. Willey lists the species from Massachusetts, and Wainio’s distribution adds Ohio, New Mexico and Jamaica. The above lists of localities would indicate quite a general North American distribution, but the plant is little known since it is generally confused with the next. Known in all the grand divisions.

Dr. Wainio gives three forms, of which only the first, a clavata (Ach.) Wainio, is at all common. Ours all seem to belong to this form, which should stand for the species

Cladonia macilenta Hoffm. Deutschl. FI. 126. 1796. Primary thallus persistent or finally dying, composed of laciniate, lobate-laciniate, cren- ate or rarely subentire, small or medium sized squamules, which are 1-4 mm. long and 1-3 mm wide, flat or somewhat involute, scattered or clus- tered: sea-green, whitish sea-green or olivaceous above, white below or darker or rarely yellow toward the base of the squamules; the margin and lower side sometimes sorediate. Podetia arising from the surface of the primary thallus, short or elongated, rather slender, subcylindrical or clavate, 5-42 mm. long and 0.5-3 mm. in diameter, cupless, simple or sparsely branched: apices obtuse or impressed, sterile or terminated by imperforate, clustered or scattered apothecia: erect, esquamulose, squamu- lose toward the base or rarely entirely squamulose: often corticate toward the base and below the apothecia, white or sea-green. Apothecia small or more commonly middling sized, o. 5-2.5 mm. in diameter, solitary or some- what densely clustered, convex, immarginate or having a thin margin, scar- let. Hypothecium pale. Hymenium red above and pale yellowish below. Paraphyses usually simple, more or less thickened at the pale or reddish apex. Asci clavate or cylindrico-clavate. Spores irregularly arranged. Plate X. Figs. 2a and 2b.

On earth, dead wood, and on soil over rocks. Found especially in rather dry, open places. Examined by the writer from Newfoundland (A. C. Wag- horne), Canada (J Macoun), Iowa and Massachusetts (Bruce Fink). In all these the spores were irregularly arranged, though some of the plants were unbranched forms, otherwise appearing more like Cladonia bacillaris. J. Macoun gives many localities in British American, but doubtless part of the material is Cladonia bacillaris instead. T. A. Williams lists from Nebraska and the Black Hills. Whether he studied the spore arrangement sufficiently, I am not able to say, but suspect not, as American workers have not usually recognized Cladonia bacillaris . H. Willey records from Massa- chusetts, and says “We have also C. bacillaris Nyl. differing only in yield- ing no reaction with iodine.” This statement follows after saying of C. macilent.a, “podetia yellow with iodine.” Willey is here following

—79 -

Nylander’s view of the difference in the two species. H. Willey and W. W. Calkins both record from Illinois, but we have no means of knowing whether the two species were differentiated or not. Cladonia bacillaris and Cla- donia macilenta seem to be scarcely distinct, but herbarium specimens indi- cate that the latter plant is more robust and more commonly branched. The spore arrangement is not easy to make out and is not always to be depended upon, as the spores may be obliquely arranged in certain asci and irregularly in others of the same plant. Tuckerman recognized only Cla- donia macilenta , which he gave a wide North American distribution. Judg- ment as to whether Cladonia bacillaris and Cladonia macilenta are distinct species must finally be based upon wide study of specimens by the statistical method, taking account of centres and ranges of variation and degree of isola- tion of various forms encountered. For the present, we can find no better way than to attempt to follow Dr. Wainio, who records the present species from all the grand divisions. It is reasonable to suppose that chemical tests may have some value in differentiating these two closely related species.

Dr. Wainio gives five forms, of which only the first and most common one has been noticed in North America. This we would regard as the species.

Cladonia didyma (Fee) Wainio Mon. Clad. Univ. 1:137. 1887. Primary thallus disappearing or rarely persistent, composed of minute or medium sized, laciniate or incised crenate squamules, which are 0.5-3 mm. long and 0.12-0. 15 mm. in diameter: somewhat involute or nearly flat, scattered or clus- tered; without soredia, sea green above, varying toward olivaceous or rarely toward whitish, below whitish, or yellowish toward the base of the squam- ules. Podetia arising from the surface of the primary thallus; short or some- what elongated, 1-45 mm. in length and o 5-3 mm. in diameter; cylindrical and without cups; simple or with erect or divergent branches: erect, clus- tered or subsolitary: decorticate, or more or less corticate at the base, whit- ish-sea-green, varying toward whitish or brownish: squamules for most part toward the base or absent; squamules, verrucae, granules or soredia minute. Apothecia medium sized, or rather small, 0.3-2. 5 mm. in diameter, solitary or more or less clustered; convex and immarginate, scarlet. Hypothecium pale or cloudy. Hymenium deep red above and pale below. Paraphyses simple, more slighly thickened toward the apex. Asci cylindrico-clavate. Spores irregularly arranged.

On old trunks, earth or rocks. Examined by the writer from Virginia (A. B. Seymour), Louisiana (A. B Langlois), Florida (W. W. Calkins). The specimens of Calkins and Langlois were submitted to Dr. Wainio. Cladonia pulchella, to which these men had referred their specimens, is a synonym. Wainio cites the species from Massachusetts, Alabama, Mexico, Guadeloupe, St. Domingo, Cuba and Martinique. Dr. J. W. Eckfeldt referred one of A. C. Waghorne’s plants from Newfoundland here, otherwise our distribution is confined to the United States and the islands. Common also in South Amer- ica and known in Asia, Africa and Australia.

Dr. Wainio referred the specimens submitted to him to his first form, Muscigena (Nyl.) Wainio. Mon. Clad. Univ. 1:141. 1887, which is the com- mon form which may well stand for the species, the only one thus far noted in North America. Miami University, Oxford, Ohio.

SPECIES OF HEPAT1CAE KNOWN TO OCCUR IN WEST VIRGINIA.

John L. Sheldon.

In so far as I have been able to find out, no one has made an intensive and systematie study of the bryophytic flora of West Virginia. Several per- sons have collected a number of species, for the most part at odd times or while engaged in regular duties. This State ought to be, and probably is, very rich in species of this group of plants. The variation in altitudes, the different geological formations, the abundance of springs and small streams, and the extent of virgin forest make conditions favorable for the growth of hepatics.

In several parts of the State that I have visited, they were abundant. Even on the campus at the university there are a number of species. Just under the windows on the north side of Woodburn Hall there is a large patch of Marchantia polymorpha , possibly introduced in waste material from the biological laboratories. In the ravine are Frullania Asagrayana, Porella platyphylla , and other species less abundant. Conocephalum conicum grows in large mats under the -falls of Falling Run, a small stream passing through the campus. These plants of Conocephalum have the odor referred to by Dr. Grout in a recent number of the Bryologist. (Grout, A. J. Notes on Recent Literature. Bryologist, 10: 3. 47. May, 1907.) It was the odor and the prominent stomata that interested me most when I first found this species growing on stones and earth along the edge of a little brook in Con- necticut. Later, when I found it fruiting in the ravines along the Missouri River in Nebraska, the fruits added new interest. Since then, I have found it many times, but the odor was always the same, the one peculiar to Cono- cephalum conicum. Often the odor has been mixed with the odor of mud and decaying vegetables, but I have not yet had the pleasure of associating it with brook trout.

And not only are there several species of hepatics on the university campus, but in the vicinity of Morgantown, where the university is located, there are many others, To the east, within walking distance, up Decker's Creek, “over Cheat,” in the Tibb’s Run region, and on to Pisgah and Cranesville there are still others, so that botany students in the university can study a fairly good number of species of hepatics in their habitats with- out much trouble. Professor Andrews (A. LeRoy Andrews, Additions to the bryophytic flora of West Virginia. Bryologist, 8: 4. 63. July 1905.) has already reported a number of species from some of these localities and donated specimens to the Agricultural Experiment Station.

It is a common practice among farmers in the limestone districts to burn the lime they use for fertilizing purposes. At Pisgah, Marchantia poly- morpha and Funaria hygrometrica were found growing around the edge of the refuse from one of these lime-piles. The luxuriant growth of the plants and the abundance of fruit suggests that they are both lime lovers. This may be a hint to those who have tried to grow Marchantia for laboratory use. At Cranesville, a few miles east of Pisgah, Marchantia grew so

•8 1 —

thickly in a black spruce swamp, from which much of the timber had been removed, that an ecologist might well call it a Marchantia formation instead of a black spruce formation. Several species of hepatics have been collected at Cranesville on the border line between West Virginia and Maryland at an elevation of about 2500 feet. The meadows around Cranesville reminded me at the time I was there of the meadows of New England, except that there were no plants of Ranunculus bulbosus.

The best place to collect hepatics that I have found is at Cheat Bridge in Randolph County. Last summer a party of us camped there for a week. We certainly landed in the rainy season, for the sun did not shine for more than a half a day while we were there, and rain fell the remainder of the time. But what a place for mosses, hepatics and lichens, and how they were growing and fruiting ! The rocks and decaying tree trunks were covered with a thick carpet of mosses and hepatics and the tree trunks with lichens. Specimens collected here have already found their resting place in the herbaria of several members of the Sullivant Moss Chapter.

The places that I have named are probably no richer in species of hepa- tics than many others in the State. The broad strip of mountains to the east and southeast, where nearly all of the larger streams have their origin, and where there is still much timber, should furnish many species not yet reported for the State. While the number of species of hepatics reported for West Virginia is not large, I have thought it worth. while to bring such records as I have been able to secure together adding the new ones that I have collected.

The following list is compiled from the Flora of West Virginia (Mill- spaugh, C. F. and Nuttall, L. W. Flora of West Virginia. Pub. Field Colum- bian Museum, 9: Bot. Ser. 1, 3, 65-276. Jan. 1896.), the Bryologist (1. c.), The Proceedings of the Biological.Society of Washington, D. C. (Morris, E. L.) Some Plants of West Virginia, Proc. Biol. Soc. Wash. 13: 171-182. Oct. 31, 1900. (Pollard, Charles L. and Maxon, William R.) Some new and additional records on the flora of West Virginia, Proc. Biol. Soc. Wash. 14: 160-163. Aug. 9, 1901, the specimens in the herbarium of the West Vir- ginia Agricultural Experiment Station, and from specimens in my own herbarium. In so far as possible, habitat and locality is given. I have not had access to the reports on the floras of the State, published before Mill- spaugh and Nuttall’s Flora of West Virginia, so that the habitat, locality and name of the collector can not be given for a number of species. Miss C. C. Haynes has examined duplicates of nearly all the specimens in the herbaria referred to and some of the originals; she has also given much valuable assistance in revising the nomenclature.

MUSCI AND HEPATICAE OF WASHINGTON, D. C., AND VICINITY.

John M. Holzinger.

It was the writer's fortune to work for three years, from 1891 to 1893, in the Agricultural Department at our national capital, as an assistant botanist. During that time I spent most of my leisure hours in exploring the vicinity of Washington for mosses, and, incidentally also for Hepaticae. The determination of the Hepaticae was entrusted entirely to Dr. A. W. Evans. The mosses I tried to work out myself, but, being a novice, I encountered many difficulties, so I sent my determinations and doubtful materials to my friend Mr. Jules Cardot, who has thus seen and corrected practically all the species recorded below. Besides, in the fifteen years that have elapsed, special students have studied the material collected by me; Mr. Cheney, the genus Amblystegium: Dr. Best, Leskea and Thuidium; Dr. Grout, Eurhynchium and Brachythecium: Mrs. Britton, Sematophyllum, Orthotrichum, etc. So that now, as a matter of fact, I can claim only the collecting and final recording of most species, for future reference.

During my study in Washington I endeavored, naturally, to make use of previous work of moss students. Only two persons seemed then to have worked on mosses, and to have left a record: the first was Mr. Rudolph Old- berg, a young druggist, a Scandinavian: the other, a Rev. E. Lehnert. Mr. Oldberg’s work was recorded in “The Guide to the Flora of Washington,” published by Prof. F. L. Ward as Bulletin No. 26 of the U. S. National Museum, in 1881. In this Guide ninety-eight Musci and twenty-nine Hepaticae are listed. Mr. Lehnert’s work is recorded in Prof. B. F. Knowl- ton’s “ Additions to the Flora of Washington and Vicinity, from April 1, 1884, to April 1, 1886,” published in the proceedings of the Biological Society of Washington, Vol. Ill, 1884-1886. Here one hundred and seventy-nine Musci and fifty-seven Hepaticae are listed. This second list is called a “ revision,” “ so kindly placed ” at Prof. Knowlton’s disposal by Mr. Lehnert, and the author proudly points out that Mr. Oldberg’s list is here augmented “ by the addition of one hundred and eleven species, of which eighty-three are Frondosi and twenty-eight Hepaticae, making a total of two hundred and thirty-eight species.”

Naturally I made use also of the collection of mosses in the National Herbarium, for purposes of comparison. So generally did I miss here the species recorded in the two lists named above that I made a systematic com- parison between these lists and the species actually represented. After thus looking for the first forty-five species listed in Mr. Lehnert’s “Revision” I confess I lost patience; for in this number I found only twelve of Mr. Old- berg’s collection and none at all of Mr. Lehnert’s. I then searched for Mr. Oldberg himself, and found he had died some years before. Mr. Lehnert, how- ever, was alive, over in Philadelphia. With him I had some correspondence, without definite result: for he could never furnish me material of species he had reported. My friend Knowlton doubtless was serious — he was a serious man— when he published “ Additions from April 1, 1884, to April 1, 1886; ” as regards this revision of the District mosses, it proved to be a real April first

—86-

joke, without any scientific basis whatever. Even Mr. Oldberg’s report was supported in so meager a way, by only about one-fourth of the species listed, that I decided then and there on supplying as a first foundation for future work on the District mosses, a list accompanied by specimens deposited in the National Herbarium. For only on this basis can rational work be done in the future.

The preparation of this list has been long delayed, owing to bread-win- ing duties. The great distance at which I live from Washington since 1893 (at Winona, Minn.) has been one serious drawback. Fortunately Prof. Edward B. Chamberlain, for some years till recently a teacher in one of the Washington schools, has taken much interest in the District mosses, and has with much sacrifice of time, collected for my use data from the National Herbarium which I could not otherwise have obtained. To him and all my other bryological friends who have in one way or another aided in determin- ing and elaborating this collection, I wish here to express my heartfelt grati- tude.

The list here offered for publication, is supported by material deposited in the National Herbarium and mostly also in my private herbarium, for every species cited. It is dedicated to future moss students with the earnest wish that in their study they may experience the same humble joy felt by the author in preparing it.

*Dr. George B. Sudworth, to whom I referred this nomenclature problem for verification, disposed of it as follows: “If Homalothecium is untena-

ble, then Cardot’s so-called sections, Euhomalothecium and Homalotheciella, are valid ; and in casting Homalothecium sp. into synonymy, the section name Euhomalothecium must stand first , and Homalotheciella second , should the former ever have to be replaced on account of any invalidity shown to exist. This is so, because a section name is. in fact, a sub-generic name, and like a sub-specific name, is raised to specific rank, and may at any time of neces- sity (and if Homalothecium be untenable, this is a case of necessity) be raised to generic rank. This cuts ouf^ a section name, but if the latter is really wanted a new one may be created. Grout’s position in passing over these two section names of Cardot’s is unsupported by any authority I know. His Burnettia must certainly fall before either of Cardot’s section names.”

FURTHER NOTES ON CLADONIAS. XIIL Cladonia cristatella and Cladonia coccifera.

Bruce Fink.

In the two species considered in this second paper on the scarlet-fruited Cladonias, we seem to be perhaps nearer certain of the brown-fruited Clad- onias than we were in the three species considered in the last paper of the series. In confirmation of this view, it may be stated that both Cladonia cristatella and Cladonia coccifera have pale-fruited varieties, which may easily be confused with such species as Cladonia mitrula, Cladonia botrytes , Cladonia pyxidata and Cladonia cameo la. Even so good a lichenist as Nylander seems to have confused Tuckerman’s Cladonia cristatella ochro- carpia with specimens of some pale-fruited American Cladonia, construct- ing therefrom his species, Cladonia substraminea , with two varieties, one from North America ’and one from South America. This illustrates the dangers of making species from a few specimens submitted, Tuckerman knowing well that his plants grew with the ordinary scarlet-fruited plants in the White Mountains. Again, the resemblance of certain forms of Cladonia pityrea to Cladonia cristatella was noted in a former paper of this series, and the former species rarely shows a tendency toward scarlet-fruited condi- tions as in some specimens collected by the writer in Iowa and determined by Dr. Wainio.

The resemblance of a pale-fruited variety of Cladonia coccifera to Clad- onia pyxidata and Cladonia carneola is noted below, and it need only be added here that the variety of Cladonia coccifera often shows fruits varie- gated with yellow and scarlet.

The two species considered in the present paper are somewhat closely related and have been confused. But Cladonia incrassata Flk. is an inter- mediate species, sometimes scyphiform and sometimes without cups, and our constantly scyphiform Cladonia coccifera need not be confused with the cup- less Cladonia cristatella.

The specimens used to illustrate this paper were both collected in Minne- sota by the writer.

Cladonia cristatella Tuck. Syn. Lich. New Eng. 55. 1848. Primary thallus usually persistent, composed of incised or crenate, small squamules, which are 2-3 mm. long and wide, commonly flat but sometimes involute, scattered or clustered, sea-green or straw-yellow above and whitish below, sometimes sorediate above. Podetia arising from the surface of the squam- ules ; usually of moderate length, 4-35 mm. long and o. 5-2. 5 mm. in diameter; subcylindrical or somewhat enlarged toward the apex, without cups ; simple, or more or less fasciculately or digitately branched toward the apex, the

branches short and obtuse, and the apex or apices commonly terminated by apothecia: the axils sometimes perforate, clustered or subsolitary; erect and rarely squamulose; cortex continuous or areolate, smooth or roughened; sea-green or straw-yellow. Apothecia medium sized or small, 0.3-3 mm. in diameter, solitary or clustered, convex, immarginate, scarlet. Hypothecium pale or pale yellowish. Hymenium pale reddish above and pale or pale yellowish below. Paraphyses commonly simple, the apices only slightly thickened or colored. Asci cylindrico-clavate. Plate XI. Fig. ia and ib.

On dead wood and rarely on earth, especially in rather dry woods. Examined by the writer from Maine (F. L. Harvey), Massachusetts (Clara E. Cummings), New York (E. A. Burt and Carolyn W. Harris), Long Island (H. von Schrenk), Ohio (E. E. Bogue, M. Foltz and Bruce Fink), Missouri (C. H. Demetrio and Colton Russell), South Carolina (H. A. Green), Illinois (G. P. Clinton and Bruce Fink), North Carolina (Colton Russell), Wisconsin, Iowa and Minnesota (Bruce Fink), Ontario (J. Macoun), Newfoundland (A. C. Waghorne, and labeled Cladonia coccifera ), Tennessee (W. W. Calkins and referred to Cladonia pulchella ). H. Willey records from Massachusetts and Illinois, W. W. Calkins from Illinois, J. W. Eckfeldt and W. W. Calkins from Florida, Charles Mohr from Alabama and C. H. Peck from New York. Wainio’s distribution adds Virginia, New Jersey, Indiana, Georgia and Texas. J. Macoun finds the plant widely distributed in British America, but neither he, Dr. H. E. Hasse, nor any other collector seems to have found it along the Pacific coast. Otherwise, widely distributed in North America. A distinctly North American lichen.

Cladonia cristatella ramosa Tuck. Obs. North Amer. Lich. 395. 1862. Podetia spreading, branched below and dichotomously much-divided above.

On sterile earth in the White Mountains, and also in Illinois according to H. Willey.

Cladonia cristatella vestita Tuck. Syn. North Amer. Lich. 255. 1882. Podetia densely squamulose, and often much like Cladonia pulchella.

From Massachusetts and New Jersey. Also a specimen sent Dr. Wainio, collected by the writer at Tower, Minnesota, was placed here.

Cladonia cristatella paludicola Tuck. Syn. North Amer. Lich. 255. 1882. Podetia very short and the apothecia almost sessile. The squamules of the primary thallus squamulose.

In Cypress and other swamps, indefinitely reported by Tuckerman. The writer has referred here a specimen collected on a log at Mankato, Minne- sota. But the squamules are scarcely sorediate, and the determination is doubtful. H. Willey records for Massachusetts.

Cladonia cristatella ochrocarpia Tuck. Syn. North Amer. Lich. 255. 1882. Apothecia sometimes yellow. Tuckerman first called this Cladonia floerkeana ochrocarpia Tuck. Lich. Amer. Excic. no. 133. 1854. Cladonia sub sir amine a Nyl. Syn. Lich. 204. i860, seems to be the same in part.

Reported as frequent on sterile soil in the White Mountains, where it is frequent and mixed with the ordinary form of the species. Also said to occur in New York and Massachusetts, H. Willey recording from latter State.

Cladonia coccifera (L.) Willd. FI. Berol. Prod. 361. 1787. Primary thallus usually persistent, composed of irregularly or flabellately incised, crenate or lobate, small or larger squamules, which are 1-^4 mm. long and 1-3 mm. wide (foreign measurements more than twice as large): flat or some- what involute, the lower side often more or less distinctly nervose; clustered, or scattered, light to reddish sea-green above and white below or yellowish toward the base, the base and the nerves yellow or red ; rarely sorediate above and at the margins. Podetia arising from the surface of the primary thallus, 4-50 mm. long and 1-4 mm. in diameter at the base, cup-bearing, cylindrical or turbinate, erect, corticate, the cortex subcontinuous toward the base and areolate-verrucose toward the top; sea-green, frequently yellowish or reddish tinged: the decorticate areas between the areoles are frequently white or yellowish; rarely more or less squamulose. Cups gradually or abruptly dilated, sometimes becoming oblique, subentire, dentate, radiate or prolifer- ate, one to four proliferations from cup- bearing cups or apothecia, prolifer- ations arising from the margins of the cups or rarely from within, the lower rank 4-30 mm. long, the upper one or more formed by proliferation usually shorter. Apothecia varying much in size, 1-8 mm. in diameter in ours (and frequently twice as large in foreign specimens) ; clustered or solitary, at the dilate apices of the proliferations or sessile on the margins of the cups: con. vex or depressed convex: thinly margined or more commonly immarginate, scarlet in ours. Hypothecium pale. Hymenium pale red above and pale below. Paraphyses usually simple, somewhat enlarged at the apex. Asci cylindrico-clavate. Plate XI. Fig. 2a and 2b.

On earth and on humus over rocks. Examined by the writer from New Hampshire (Clara E. Cummings, G. K. Merrill and R. H. Howe, Jr.), Massa- chusetts (Clara E. Cummings), Connecticut (H. A. Green), New York (Caro- lyn W. Harris), Iowa, Minnesota, Washington, British Columbia, Alberta (Bruce Fink), Montana (R. S. Williams), Ontario (J. Macoun), Alaska (Wm. Trelease). Chas. Mohr records from Alabama, C. H. Peck from New York, H. Willey from Massachusetts and J. Macoun from many localities in British America. Dr. Wainio’s distribution adds only Gautemala. A large part of specimens are recorded under the synonym, Cladonia cornucopioides (L.) Fr. These forms fall .mainly at least under Cladonia coccifera stematina (Ach.) Wainio Mon. Clad. Univ. 1: 158. 1887, which is the normal form and which we prefer to let stand with the species. Widely distributed in north- ern United States, British America and southward in the mountains. Tuck- erman records from Oregon by Hall, otherwise the collections of the writer from Washington seem to be the only ones from the west coast, within the United States. Known in all the grand divisions except Africa.

Cladonia coccifera pleurota (Flk.) Schear. Lich. Helv. Spic. 25, 1823. Podetia corticate below and more or less sorediate above. Squamules usually sorediate below and along the margins.

Examined by the writer from New England (Clara E. Cummings), New Hampshire (R. H. Howe, Jr.), Massachusetts (H. Willey), Iowa, Minnesota and British Columbia (Bruce Fink), Nova Scotia and Newfoundland (A. C.

IOU —

Waghorne), Alaska (Wm. Trelease). Recorded from Montana by Carolyn W. Harris. Dr. Wainio’s distribution adds Greenland, North Carolina and California. Thus the variety seems to be as widely distributed in North America as the species, but it is much less common in most localities. Its foreign distribution is also the same as the species.

Cladonia coccifera ochrocarpia Flk. in Sommerf. Suppl. FI. Lapp. 128. 1826. Apothecia yellow, the podetia without soredia.

Recorded by H. Willey from Massachusetts. Found also in Europe.

The plant is little known and is easily confused with Cladonia pyxidata on account of its yellow apothecia. Also easily mistaken for Cladonia carneola, but this always has podetia sorediate toward the top. The plant may be distinguished from Cladonia pyxidata by a careful comparison of the primary thallus. Doubtless to be found elsewhere in North America

The greatest number of changes occur in the Pfookeriaceae, which are split up into thirteen genera, only three of which contain North American species: Cyclodictyon varians (Sull.) Broth, replaces H. varians Sull. Cal- licostella cruceana (Dub.) Jaeg. replaces H. cruceana Duby. Hookeria Sm. is restricted to five species, and Pterygophyllum lucens is replaced by H. lucens(L.) Sm., which is congeneric with H. Sullivantii from North America

and H. acutifolia Hook, from “Nepal and Sikkim, Ceylon and Java, Guade- loupe, Ecuador and Brazil.” We have three sets of specimens of this species from Jamaica in fruit and careful comparisons recently made with the type from Nepal, India, and with other specimens and exsiccatae cited below, have forced a conviction that H. Sullivantii C. M. is identical with it. Fruiting specimens were collected in Virginia and figured in the Memoirs of the Torrey Botanical Club for 1894. Sullivant issued his Nos. 270 and 401 of the Musci bor. Am. as H. acutifolia? and this query proves to be true.

NOTES FROM WATERVILLE, NEW HAMPSHIRE. II.

Annie Lorenz.

In the Bryologist for November, 1906, the writer published some notes on the bryophytes of Waterville, N. H. A more critical inspection of Water- ville during the past August, together with the examination of specimens col- lected in 1906, has resulted in some further species of interest.

The prolonged cold of the previous winter has not only made everything noticeably behindhand, but has badly winter-killed many of the rock-grow- ing mosses. Also, as the early part of the summer was extremely wet, there are abundant young sphorophytes for next year.

Marsupella EMARGiNATA(Ehrh.) Dum. is common in every available situ- ation, even among the stones in a sandy pitcher-plant bog. The water was very low on account of the August drought, and these plants had young peri- anths. At the Cascades station, where it grows on the western faces of the granite rocks, there had been abundant capsules, but they were nearly with- ered away. by early August. %

Further exploration of the neighboring summits produced Frullania Oakesiana Aust. and Hypnum Jamesii{Sn\\.) L. & J. all over the balsam scrub. On Osceola were Lophozia lycopodioides (Wall.) Cogn. rather small, but ade- quately spinulose, and Sphenolobus minutus (Crantz) St. which is abundant on the ledges below the summit.

At the “ V, ” the curious ravine to which reference was made in the

— 103 —

former notes, are Jungermannia sphaerocarpa Hook., Lophozia alpestns (Schleich) Evans and Tetraplodon mnioides B. & S. Fertile Blindici is unusually abundant this year.

Anacamptodon splachnoides (Froel. ) Brid. occurred at two stations, both on yellow birch. The larger patch was on a big birch hangingout over a gully, nevertheless the writer did not find it inaccessible. In the writer’s opinion Anacamptodon is overlooked rather than rare. It evidently grows about holes on any kind of broad-leaf, and facing in any direction, although fruiting more heavily with a southern exposure. A more or less permanent supply of moisture is necessary for the production of capsules. The writer has it from two stations in Massachusetts, one in Deerfield, a three-foot strip solid with fruit. Both of these were upon sugar-maple.

Only Bryum argenteum L. and 7?. bimum Schreb. are noted, the latter on wet corduroy in company with Riccardia pinguis (L.) S. F. G. Thuidium Blandovii (W. & M.) B. & S. appeared in the cranberry bog, Fontinalis anti- pyretica L. gigantea Sull. in a little brook on the A. M. C. path, and F. Dalecarlica B. & S. on rocks in Mad River at Tyler’s Spring.

Dicranodontium also lives on an old root at a cold spring on the trail up Osceola, at about 2500 ft. alt.

No part of the White Mountain territory has been as yet explored with absolute minuteness, and Waterville is no exception to the rule.

MRS. MARY L. STEVENS.

Our readers will learn with regret of the death, on September 17th, 1907, of a charter member of the Sullivant Moss Chapter, Mrs. Mary L. Stevens. Her active interest in the Chapter caused her to be well known to many, and those whom she could help she served well and faithfully. She was ever as eager to find material to offer as she was to accept what others offered.

Her interest in botany dates back many years, and her herbarium shows great painstaking, and contains beautiful speciments of ferns, mosses and liehens. She showed unusual talent in painting flowers, and among her numerous sketches are two sets of mushrooms and orchids that are excep- tionally well handled. She was careful to keep all interesting notes on mosses that she learned either from her own observation or from those who kindly helped her to determine specimens. These notes she neatly arranged and bound together, with an accompanying colored sketch of each moss, making a valuable note book for beginners.

Those who knew her personally found Her always ready to share her specimens, and glad if she could pass along any bit of information. As one friend has said, we all have had a big slice of pleasant and helpful friendship taken out of our lives. Elizabeth Marie Dunham.

LEUCOBRYUM GLAUCUM SCHP.

By W. H. Burrell, F.L.S.

Leucobryum glaucum Schp. , in unattached double convex discs, has recently been detected in Norfolk, England, enabling me to take an active interest in the two previous records, published in Dixon’s “Handbook of British Mosses,” and in The Bryologist, Vol. IX, No. 4, July, 1906. The former describes spheroidal balls or cushions from Hedsor, Bucks, entirely unattached, consisting of stems radiating outwards from a central point. The latter refers to an apparently similiar cushion found by B. D. Gilbert in hemlock woods in Otsego Co., New York, which was observed to be rest- ing in a matrix, of its own diameter, and about half an inch deep. Mr. Gil- bert offers no explanation as to how the cushion separated itself and developed its radiate growth, neither does he state what the underlying cup was composed of; if it consisted of the older portions of Leucobryum stems, from which the cushion had separated, there is no analogy between the Otsego and Norfolk examples; if, however, the cup was composed of earthy matter, similar causes may have originated the cushions, heavy rain or flood causing it in this instance to become embedded.

A careful study of the large quantity of material at hand leads me to expect this form of Leucobryum to be wide spread and frequent; it is with the object of stimulating observation that this note is prepared.

In the parish of Aylmerton, Norfolk, on the slope of a hill, under the shade of beech trees, several hundreds of small cushions of Leucobryum are growing, a series of intermediates showing the connection between normal plano-convex tufts firmly attached to the forest soil and double convex unat- tached discs exhibiting no distinction between base and summit. Some are resting on fallen leaves of the previous autumn to which they are attached by radicals and mycelium ; others are resting on their convex surface with the plane earth-covered base directed skyward through inversion: one fine tuft four inches (10 cm.) in diameter, with a clean base devoid of earthy mat- ter was resting on a bed of Mnium hornum L. : it had been there long enough for the base to conform to the inequalities of the underlying moss and the lat- ter was slightly discolored ; others had in varying degrees pushed out new growth, illustrating stage by stage the gradual formation of the double con- vex cushion. Perfect cushions are the exception, rather than the rule, though many occur.

The rigid habit of the plant, its method of vegetative reproduction and the structure of the leaves are important factors in the development of the

form under discussion. The leaves of most mosses are built up of a single layer of cells which quickly part with their moisture in dry air and as readily re-absorb it from damp air. The leaves of Leucobryum, however, have a remarkable cell structure allied to that of Sphagnum, consisting of a single layer of chlorophyllose cells (Fig. 2a) embedded in 2-8 layers of empty hya- line cells whose adjoining walls are perforated with bordered pores (Fig. 2b). When the hyaline cells are filled with water the green color of the embedded chlorophyllose cells is seen: when water is displaced by air the plant assumes a dirty white color suggestive of the name leucobryum — white moss. The water held by these cells after rainfall can be squeezed out as from a sponge and renders unattached tufts self-sustaining on the same prin- ciple that camels can exist for considerable periods in arid deserts— they carry their own supply. In Braithwaite’s British Moss Flora reference is made to the abnormal vitality of the genus, and persistent growth even in the drying press; dipping in boiling water before pressing is recommended to prevent dehiscence of the capsule.

Leucobryum is not a frequent fruiter: in compensation for the rarity of spore formation new growth proceeds from buds developed from radicals which are freely formed on the surface of the leaves. (Fig. 1). Regardless of the position of the parent tuft these buds develop geotropically at which- ever surface happens to be uppermost at the time. The double convex form assumed by the most perfect tufts, and to which all conform more or less, is favored by the rigid habit of the plant and by its squat growth in the local- ity referred to. In its most luxuriant form Leucobryum is a denizen of swamps where it forms large bosses 6-8 inches high, but at Aylmerton the average height is 1 ^ inches (3-q cm.). A tuft torn from a deep boss, would lie prostate: but the short tuft when disturbed has a tendency to come to rest either in its normal position or completely inverted, alternating growth taking place in two definite directions: too much stress must not be laid on this because many examples occur of single stems lying prostrate and pro- ducing plano-convex cushions half an inch (12 mm.) in diameter, by the devel- opment of buds from the apical leaves. Displaced plants do not to any great extent appear to recover an erect position by curvature of the stem; they remain in the position accident assigns them and form a frame work to which the new growth from buds conforms.

Assuming that I am correct in attributing the unattached state to acci- dental and repeated disturbance, which brings into play the natural vitality of the plant, and stimulates bud formation, it is not difficult to suggest a cause for the disturbance. The tread of woodmen and sportsmen and the removal of timber play their part, but in well stocked game preserves I have long been familiar with displaced moss, especially Dicranum scoparium Hedw., and I have attributed this to the scrapping of pheasants. In open moorland, where Dicranium forms dense masses, the ground is often lit- tered with small tufts which apparently depend upon chance conveyance to a congenial spot for continued existence. In woodland, similar displace- ment takes place with a slightly different result; in the cool shade Dicranum

— no—

forms lank lax tufts; when disturbed the stems lie prostrate but growth is hardly arrested: by an exaggeration of the geniculate curve which is a feature of several species, the apiees recover a vertical position and re-establish themselves: in this case balls are not formed but vitality is preserved by a curvature of the stem.

In large game birds may be found, I believe, an ever present and ever active agency for the periodical disturbance necessary.

The activity of these birds may be gauged by an examination of a chest- nut grove in winter, when not a nut will be found ; hundreds of torn and empty husks will show that birds have fed there. The Leucobryum site at Aylmerton is under beech trees, and the fallen nuts give a direct reason for special attention from birds.

It will not be out of place to refer to another roving moss mentioned by H. N. Dixon, in a paper on the moss flora of Northamptonshire, published in Journ. of Northamptonshire Nat. Hist. Soc. Vol. X. 1899. The author says: “A remarkable form of Porotrichum alopecurum Mitt, occurs in

“ Weldon Quarries, which I have not found, or seen noticed, elsewhere. On “ a recent visit in the spring of 1898, the bottoms of some low depressions “ under trees were carpeted with globular mosses, which were found to con- “ sist of living ‘ balls ’ of this moss, entirely detached from the soil and with- “ out rootlets, and from two to four or five inches in diameter. The interior “of the ‘ balls’ consisted of the rigid, wiry stems proper to the species, which “had branched profusely in all directions, and so produced this peculiar “ form. The branches were extremely dense and numerous, many hundreds “ of secondary stems going to make up a single tuft or ‘ ball,’ and entirely “ hiding the central stem or stems. From this, as well as from the size of “ the tufts, it was clear that they must represent the growth of many months, “ probably of several years, and this without connection of any kind with the “soil or other matrix; so that the nutriment must have been obtained “entirely from atmospheric moisture; they were, however, perfectly fresh “ and vigorous. No doubt detached stems of this moss, the ordinary form of “which was growingin close proximity, has been carried at various times by “ the wind into the hollows, where the moisture of the air, together with the “natural vitality, apparently a marked character of the species, combined “ not only to resist decay, but even to promote growth, resulting in the very “ unusual phenomenon described.”

In a later note Mr. Dixon records a similar growth of Porotrichum alope- curum in Ireland, reported by the Curator of the Fernery, Botanic Park, Bel- fast, who called it “ the rolling moss,” and described how it grew without roots and was blown about from place to place by the wind; he kept it as a curi- osity among his ferns.

The unattached state of Leucobryum and Porotrichum bears no relation to the Wind Witches described by Kerner in Nat. Hist, of Plants, Vol. II, page 850. According to the author a number of herbaceous plants, inhabiting the Steppes of southern Russia, contract into flattened balls at maturity, and, becoming detached from the soil, are rolled along by gusts of wind. The

II —

object achieved here is the distribution of seeds: the withered plants lie in sheltered nooks to which they have been blown until the rainy season, when, under the influence of moisture, the seed vessels open and the seeds are washed out. The plants themselves are dead, but in the case of the mosses vitality is maintained for a succession of years.

NOTES ON SPORE DISPERAL IN SPHAGNUM.

E. J. Winslow.

On August 9th of the present year, while botanizing in a swamp near Lake Willoughby, Westmore, Vt. , my attention was attracted by the frequent recurrence of a snapping sound like the breaking of a wheat straw. Upon investigation I found that the Sphagnum, which grew abundantly all around, was heavily fruited, and the strongly inflated capsules as they dried out in the mid-forenoon sun, were expelling their spores with the little explosion that I had noticed. I was never able to catch a capsule in the act, but by following the sound quickly I could catch a glimpse of a tiny and very transi- ent cloud of reddish brown spores two or three inches from the top of a bunch of capsules.

I tried unsuccessfully to procure the effect by squeezing the capsules between the thumb and finger, but from a bunch which I gathered and carried in my hand the popping continued until most of the ripe capsules were exploded. As far as I could see there was no breeze or other disturbance to aid in producing the explosion, but the plants were exposed to the direct rays of the sun, and it was the time of day (about 10 a. m.) when the last of the dew was disappearing from the ground. So it would seem that perfect dry- ness is the only condition necessary to produce the discharge in a ripe cap- sule. Elmira, New York.
