Except in New Jersey and California the species of Riccia (in its restricted sense) have not been very diligently collected in North America. This has been true even in New England, where the dis- tribution of the Hepaticae has been studied more thoroughly than in most other parts of the United States. Until about a year ago, when R. sorocarpa was reported from several localities,! R. arvensis was the only member of the genus definitely known to occur within our limits. During the past season, however, four additional species. have been detected in Connecticut. Three of these, R. Austini,. R. dictyospora, and R. Lescuriana, were found in or near New Haven, while the fourth, R. hirta, was found near Hartford. These four species, together with R. arvensis, are discussed in the present paper. Three other additions to the New England flora are likewise included. The first is Nardia scalaris, a species common in Europe but rare in America; the second is an Odontoschisma which European writers consider a variety of O. denudatum but which seems worthy of recog- nition as a distinct species; the third is Anthoceros crispulus, a species recently segregated from A. punctatus. At the close of the paper several additions to local state floras are enumerated. ]. RiccrA ARVENSIS Aust., Proc. Acad. Philadelphia for 1869: 232. Muddy shores of ponds and rivers, more rarely in fields. Rhode Island: listed in Bennett's Catalogue but without definite stations. Connecticut: Hartford (E. B. Harger); Wethersfield and West Hartford (Miss Lorenz); Orange and Middlefield (4. W. E.); East 18ee Sheldon, Bryologist 13: 64. 1910. Also Evans, RHopoma 12: 193. 1910. a Rhodora [JANUARY Haven (G. E. Nichols). The species has been reported also from the following localities: Closter, New Jersey (Austin), where the original material was collected; near Hull, Quebee (Macoun); Ottawa, Ontario (Macoun); near Richmond, Staten Island, New York (Howe); Highlands, New Jersey (Miss Haynes); Lehigh Mountain, Pennsylvania (Rau); Georgetown, District of Columbia (Coville). The color of R. arvensis is a dull grayish green, sometimes pigmented with purple along the margin. The older parts of the thallus often show a yellowish hue. Although the species sometimes forms rosettes 0.75-1 cm. in diameter, the plants frequently grow scattered or in irregular mats. Under unfavorable conditions the thallus is minute and unbranched, and specimens with mature capsules have been observed in which the entire plant was only 1 mm. long and 0.5 mm. wide. It is much more usual, however, for the thallus to fork from one to three times, and the branches when well developed measure 1.5-2 mm. in width and 2-3 mm. in length. The terminal branches are very bluntly pointed, rounded, or subemarginate at their extremi- ties and bear on the upper surface a shallow median groove, occupy- ing about one third the width of the thallus. This groove contracts abruptly at the apical end into a very narrow sulcus; toward the base of the branch it usually becomes more or less obliterated, especi- ally after capsules are developed, the upper surface thereby appearing plane or nearly so. In some cases, however, the groove can be demon- strated, more or less clearly, almost to the base of the plant. From the sides of the groove the flanks of the thallus gently curve away, and the branches are bounded laterally by rounded ridges. The ventral scales do not extend beyond the margin; they are usually hyaline and inconspicuous but are sometimes tinged with purple. In most cases cilia are absent altogether. When present they are commonly scanty and poorly developed, being scarcely more than slightly projecting cells with rounded ends. In cross section the lower surface of the thallus is seen to be plane or a little convex in the median region, the sides rising obliquely or abruptly and meeting the upper surface at an angle of 90 degrees or less. The section is therefore approximately a rectangle or trapezoid. "The thickness of the thallus is from one third to one half as great as the width. The epidermal cells are thin walled, rounded, and hyaline; they soon collapse and disappear more or less completely, the cells of the next layer then losing their chlorophyll and functioning as an epidermis. 1912] Evans,— Notes on New England Hepaticae,— IX 3 The species is monoicous, and the capsules, which are abundantly produced, are irregularly scattered along the median portion of the thallus. At maturity they can readily be seen through the trans- lucent tissues as a series of dark spots, and when the plants become dry the capsules protrude above the upper surface. The spores are dark brown and average about 85 u in diameter. All four faces are clearly reticulated, and a distinct wing 5-10 u wide is developed at the junction between the convex face and the three plane faces. The wing is yellowish brown and crispate, the margin being more or less crenulate and the surface minutely verruculose. On the convex face of the spore there are about eight meshes across the diameter, and the meshes measure about 10 uw in width. In profile view the ridges which bound the meshes appear low but project at the angles of the meshes as truncate points, perhaps 5 u in length. The plane faces have lower ridges than the convex face but are otherwise much the same. There seems to be little to distinguish R. arvensis from the European plant which is now usually known as R. bifurca Hoffm. This species was published in 1795,! but the original description is very incomplete and would apply equally well to a number of distinct plants. The type material is apparently no longer in existence. For these reasons the name R. bifurca, although it continued to be used by authors, had no definite signification until the end of the last century. As late as 1892 Camus,? in reviewing what was known about the species, pronounced it very badly understood and even hypothetical. It was not until 1898, when the subject was investigated by Heeg,’ that the species became defined in its present sense. He based his conclusions upon the specimens which Lindenberg,‘ in 1836, referred to R. bifurca, but unfortunately even these specimens did aot lead to definite results. In the fascicle labeled R. bifurca, Heeg found four distinct species and simply selected the one which seemed to him to coincide best with Lindenberg’s description and figures. He reserved the name for this particular species and referred to R. bifurca, as thus restricted, a number of specimens from various localities in Sweden, Switzerland, and Austria. These he described clearly and fully. His conclusions 1 Deutschlands Flora 2: 95. 1795. ? Bull. Soc. Bot. France 39: 229. 1892. 3 Bot. Not. 1898: 107. 4 Nova Acta Acad. Caes. Leop. Carol. 18: 425. pl. 20, f. 1. 1836. 4 Rhodora [JANUARY soon became accepted by European writers, and R. bifurca is now recognized as a definite species throughout northern Europe. Whether or not the course pursued by Heeg was justifiable is a question. It would probably have been better if he had given up the name R. bifurca altogether and had chosen a new name fer the species. At any rate it must be admitted that the present definition of R. bifurca is Heeg’s and that it is very doubtful whether his conception of the species would agree with Hoffmann’s or even with Lindenberg’s. In case it should be proved beyond question that R. arvensis and Heeg’s R. bifurca were identical, the writer suggests that the species should bear the name given it by Austin. One of the closest allies of R. arvensis is apparently R. glauca L., a common European species which is known in North America from California only. This species is perhaps to be expected in the eastern United States. Its thallus differs from that of R. arvensis in having sharper margins and in being relatively thinner, the thickness being only one fourth as great as the width or even less. The spores of R. glauca are much like those of R. arvensis, except that the meshes of the convex face average a little larger. 2. Riccra Austini Steph., Bull. de l'Herb. Boissier 6: 336. 1898.

The species was based on material collected by Austin near Closter, New Jersey, and issued as R. lamellosa. Its geographi- cal distribution is very incompletely known. Underwood ! reported R. lamellosa from Ontario, Alabama, and California, as well as from New Jersey, and the same species is listed without definite stations in Bennett’s Plants of Rhode Island. The Californian material in the Underwood herbarium has since been described by Howe? as a dis- tinct species under the name R. americana, but it is probable that some of the eastern specimens would now be referred to R. Austini. Unfortunately the question cannot be answered at the present time. 1 Bot. Gaz. 19: 278. 1894. 2 Mem. Torrey Club 7: 24. pl. 90. 1899. ae ee ee 1912] Evans,— Notes on New England Hepaticae,— IX 5 The true R. lamellosa is a species of the Mediterranean region, and all records of its occurrence in North America need careful inves- tigation. The thallus of R. Austini is of a pale glaucous green color and is apparently never pigmented with purple. It sometimes forms a complete rosette about 1.5 cm. in diameter but often fails to do so, and the plants then occur irregularly scattered or in more or less com- pact mats. The thallus forks from one to three times, the branches measuring 1.5-3 mm. in width and 3-4 mm. in length. The terminal branches taper gradually to blunt points. On the upper surface in the apical region a deep and narrow sulcus is visible, from which the flanks curve abruptly away. The sulcus is usually very short and the older parts of the thallus are plane or nearly so. The ventral scales are large, crowded and hyaline and project considerably beyond the margin of the thallus, thus forming a distinct translucent border. The margins of the scales are either entire or minutely and irregularly crenulate from projecting cells. The plant is quite destitute of marginal or surface cilia. In cross section the lower surface appears plane or slightly convex in the median region, while the sides ascend obliquely and meet the upper surface at a sharp angle of about 60 degrees. The thickness of the thallus is usually from one fourth to one third as great as the width. The epidermis consists of colorless and rounded thin-walled cells, which soon break down. Their place is taken by the second series of cells, which gradually lose their green contents but retain their thin walls. Although the species is monoicous the capsules are not abundantly produced. In fresh material they are completely hidden until the tissue above them begins to discolor and to become disintegrated. The spores are brown and measure 85-100 u in maximum diameter The angles between the faces of the spore are rounded, and there is no wing developed at the junction between the convex face and the three triangular faces. The convex face is covered over with anasto- mosing ridges about 2 u high, which form a distinct reticulum, and the ridges do not project appreciably at the angles of the meshes. The latter number about nine across the face of the spore and average about 10 u in width. The triangular faces are marked with still lower ridges, irregularly arranged and not forming a network. The three related species, R. Austini, R. americana, and R. lamellosa, form a definite group characterized by a flat thallus destitute of cilia 6 Rhodora [JANUARY but bordered by a series of imbricated, hyaline scales. "The spores in the two American species afford the best differential characters in separating them from R. lamellosa, in which a distinct wing is developed at the junction between the convex face of the spore and the three plane faces. The absence of a wing in the American plants which had been referred to R. lamellosa was first pointed out by Under- wood.' The spores in the true R. lamellosa are further distinguished from those of R. Austini by their slightly larger size (90-120 u accord- ing to Müller ?) and by the fact that all four faces are reticulated. In R. americana, also, the spores are larger than in R. Austini, measuring 90-126 u according to Howe, and the meshes of the convex face are likewise larger, averaging about 15 u in width. The thallus has even more conspicuous scales than in the eastern plant and is slightly more robust, measuring 2.5-4 mm. in width. Howe’s figures of R. ameri- cana should be carefully consulted in studying R. Austini. 3. Riccra picryospora M. A. Howe, Bull. Torrey Club 28: 163. 1901. On moist black earth in a path among rocks, in company with R. sorocarpa and Grimaldia fragans. West Rock Ridge, Woodbridge, Connecticut (4. W. E.). New to New England. Known from only two other stations, namely: Athens, Georgia (H. M. Harper), the type locality, and Glencoe, Missouri (N. L. T. Nelson). A portion of the original material, kindly communicated by Howe, agrees closely with the specimens from Connecticut, except that the spores are a little larger. In R. dictyospora the color is a more decided green than in either of the preceding species and is only slightly glaucous. The plants sometimes form irregular rosettes 1.5-2 cm. in diameter but are much more likely to grow in intricate mats or irregularly scattered. The thallus is narrow, measuring about 1 mm. in width, and the branches are mostly 2-3 mm. long. They tend to spread less widely than in most species of Riccia. The terminal branches have rounded or slightly emarginate apices. Near the tip a narrow median sulcus can be demonstrated, but this extends backward for a short distance only, the older parts of the thallus being plane or nearly so on the upper surface. The thallus is destitute of marginal hairs but bears a series of ventral scales, which extend slightly beyond the margin. These are usually deeply pigmented with purple and form a narrow ! Bot.

As seen in cross section the lower surface is convex in the median region, the sides rising obliquely and meeting the upper surface at a sharp angle. The thickness of the thallus is usually about half as great as the width. The epidermal layer is composed of thin-walled rounded cells without chloroplasts. These soon collapse and either disappear completely or persist as cup-shaped vestiges. In most cases the second layer of cells, which are likewise rounded and thin-walled, remains intact and assumes the functions of an epidermis. The plants are monoicous. The capsules are sparingly produced and are difficult to discover until the tissue above them has become broken down. The spores are brown and average about 100 u in diameter in the type specimen and about 90 u in the Connecticut material. They agree with the spores of R. Austini in having no wing developed at the junction between the convex face and the three plane faces. "The whole surface is covered over with a distinct reticu- lum which is not interrupted even at the rounded angles of the spore. The reticulum is formed by a system of low ridges which project at the angles of the meshes as truncate papillae. "These papillae, as Howe shows, are 6-9 u long on the convex face of the spore and only 4-5 u on the triangular faces. He brings out the fact also that the meshes on the convex face measure 8-12 u in diameter, while those on the other faces are slightly larger. Howe’s account of the species is so full that the above description adds no new points of importance. The remarkable spores of R. dictyospora will serve to distinguish the species from most of the other members of the genus. In size and general appearance the plant bears considerable resemblance to R. sorocarpa, in which the thallus bears a similar narrow sulcus in the apical region. In R. sorocarpa, however, the sulcus is even sharper, and the color of the plant is more distinctly glaucous. The species is further distinguished by its delicate and hyaline ventral scales and by its very different spores, which measure 70-90 u in maximum diam- eter and develop a distinct though narrow wing. In R. nigrella DC. the thallus agrees with that of R. dictyospora in being bordered bya series of slightly projecting purple scales. The spores, however, are smaller, measuring 60-80 u, and are further characterized by the presence of a narrow wing. R. nigrella is widely distributed in south- ern Europe and in North America is definitely known from California. According to Austin it occurs also in New York and Pennsylvania, 8 | Rhodora [JANUARY but no recent collections of the species have been made in the eastern United States. 4.

In the bed of an old canal. West Hartford, Connecticut (Miss Lorenz, 1911). New to New England. The species has a confused history and its range is very incompletely known. It was based on specimens col- lected by Austin at Closter, New Jersey, and distributed in his Hep. Bor.-Amer. 142 as a variety hirta of R. arvensis. When Underwood raised the variety to specific rank he associated with 1t specimens from California and drew his account of the spores largely from these speci- mens. The Californian plant was soon afterwards described as a distinct species by Howe under the name R. trichocarpa,! thus leaving nothing except the New Jersey plant to represent the true R. hirta. According to Howe the material issued under No. 142 is not homogene- ous, some of it being clearly R. Lescuriana, but in the set of Hep. Bor.-Amer. examined by the writer the specimens under this number seem to be free from admixture and. agree very well with those from Connecticut. They agree also in most respects with the description of R. hirta given by Stephani,” assuming that his spore-measurements are increased 20 per cent., as Schiffner? suggests. Stephani records the species from Louisiana (Langlois), as well as from New Jersey. The Connecticut specimens of R. hirta do not form rosettes but grow in intricate mats. The color is a grayish green, much like that of R: arvensis, and the margin is sometimes tinged with purple. An individual thallus is occasionally simple but is usually once to three times dichotomous. It measures 1-1.5 mm. in width, and the branches are mostly 2-3 mm. long. The terminal branches are rounded at the extremity and show a very narrow but shallow median sulcus which extends back from the apex for a distance of about a millimeter. At the basal end the suleus is usually abruptly oblit- erated but occasionally widens out into a very short groove. The older parts of the thallus are plane or nearly so on the upper surface. 'The ventral scales are hyaline and inconspicuous and do not extend beyond the margin. "The cilia or hairs, which give the species its 1 Bull. Torrey Club 28: 184. pl. 337. 1898. Mem.

They are mostly confined to the margin but a few sometimes appear scattered over the upper surface. Those on the margin occur singly or in pairs. The cilia are whitish and usually sharp-pointed and have a length of 0.07-0.15 mm. In cross section the lower surface appears more or less convex in the median region, while the sides rise obliquely and meet the upper surface at a sharp angle of about 60 degrees. The thickness of the thallus is from one third to two thirds as great as the width. The epidermis is much the same as in R. arvensis. The species has a monoicous inflorescence and produces an abun- dance of capsules, which show more or less clearly through the translu- cent tissue above them. The mature spores are brown and measure 85-100 « in maximum diameter. At the junction between the convex face and the three plane faces a narrow wing 5 u or less wide is devel- oped, and this wing is indistinctly erenulate and very minutely verru- culose. The convex face is covered with a regular reticulum, the meshes numbering about seven across the diameter and measuring about 12 » in width. At the angles of the meshes the bounding ridges project as short and rounded protuberances. On the triangular faces of the spore the ridges are lower than on the convex face; they sometimes form an incomplete reticulum but are usually vermicular and unconnected. Although a strong superficial resemblance exists between R. hirta and R. arvensis it is not difficult to distinguish them. The cilia of R. hirta afford the most striking difference, the thallus of R. arvensis being usually smooth throughout. European writers, however, have shown that cilia oecur exceptionally in species which are usually smooth and that they are sometimes absent in species which are usually ciliate. It is therefore unwise to emphasize too strongly a difference derived from the presence or absence of cilia alone. For- tunately A. arvensis and R. hirta show other differences of a more trustworthy character. In R. arvensis, for example, the upper sur- face of the thallus bears a broad median groove, while in R. hirta it usually bears a narrow sulcus only. R. arvensis is further distin- guished by its slightly smaller spores, reticulate on all four faces; in R. hirta the reticulum is usually distinet on the convex face only. In R. trichocarpa, according to Howe, the spores are more opaque and slightly larger than in R. hirta, the margins of the thallus are rounded rather than acute, and the cilia are much more numerous and longer, attaining a length of 0.3—0.65 mm. 10 Rhodora [JANUARY 5. Riccta Lescurtana Aust., Proc. Acad. Philadelphia for 1869: 232. R. glaucescens Carringt., Grevillea 8: 41. 1879. On moist black earth in paths among rocks, in company with R. Austini and R. sorocarpa. West Rock Ridge, New Haven, Connecticut (G. E. Nichols, 1911). New to New England. The original material of R. Lescuriana was collected by Austin near Closter, New Jersey, and distributed in Hep. Bor.-Amer. /43. "The species has since been recorded from Jacksonville, Florida (J. D. Smith), from Fort Ross, California (M. A. Howe), and from Illinois (on the authority of Austin). In 1898 Heeg! reported its occurrence in Europe, citing specimens from numerous localities, and reduced R. glaucescens to synonymy. In its most typical condition R. Lescuriana forms rosettes 1.5-2 cm. in diameter, but the plants more frequently grow irregularly scattered or in indefinite mats. Their color is green when fresh with a somewhat glaucous cast, much less marked, however, than in R. Austini and R. sorocarpa. As the plants grow older they sometimes become more or less tinged with yellow. "The margin is often the same color as the rest of the upper surface but is occasionally pigmented with purple, and purple spots usually appear over the capsules as they approach maturity. The thallus forks from one to four times, the branches measuring 2-3 mm. in width and about 3 mm. in length. "The termi- nal branches are rounded or bluntly pointed at the apex; on the upper surface they show a shallow median groove about one third the width of the thallus, bounded on each side by a rounded ridge. The groove is usually about a millimeter in length; at its apical end it becomes abruptly obliterated through the convergence of the lateral ridges; toward its basal end it gradually becomes flattened out, leaving the older portions of the thallus plane or nearly so. The ventral scales do not extend beyond the margin; they are commonly hyaline and inconspicuous but sometimes show a purple pigmentation. Near the margin of the thallus several series of cilia can often be demon- strated. They average about 0.15 mm. in length and are usually bluntly pointed. According to Heeg these cilia are short-lived and are sometimes scanty or absent altogether. In the West Rock specimens they are very well developed, and their presence is empha- sized by Austin in his original description. He even describes two varieties, cruciata and trichotoma, based largely on differences in the ! Bot. Not. 1898: 111. 1912] Evans,— Notes on New England Hepaticae,— IX 11 length of the cilia. In cross section a convex median region becomes apparent on the lower surface of the thallus, the sides rising obliquely and meeting the upper surface at an angle of 90 degrees or somewhat less. The thickness of the thallus is from one third to one half as great as the width. The epidermal cells are thin-walled and hyaline, the shape varying from broadly ellipsoidal to pyriform. They soon collapse and disappear, but the cells of the next layer then become hyaline also and apparently act as an epidermis. 'The inflorescence is monoicous but the capsules are not always abundant. The spores are brown and average about 100 u in diame- ter. The convex face develops a regular reticulum with about eight meshes across the diameter, the individual meshes measuring about 12 u in width. The ridges bounding the meshes are very low but sometimes project slightly at the angles as truncate or rounded papil- lae. Between the convex face and the three plane faces a narrow hyaline wing, 2-10 u wide, is formed, the margin of which is minutely and irregularly crenulate. The plane faces are marked with still lower ridges than the convex face; in most cases they scarcely anasto- mose, but sometimes a more definite reticulum is formed. Lindberg! referred R. Lescuriana as a synonym to R. Michelii Raddi, a species of southern Europe, which has since been described in detail and figured by Levier? The two species are, indeed, very closely related, and Müller? emphasizes the fact that the ciliate form of R. Lescuriana can be distinguished from R. Michelii only with difficulty. Apparently the median groove extends farther backward in R. Micheli than in R. Lescuriana, and the epidermal cells are rarely or never pyriform. The most important difference between the two species, however, is in the inflorescence, R. Michelii being dioicous and R. Lescuriana monoicous. Among the species of the eastern United States R. arvensis bears some resemblance to R. Lescuriana and agrees with it in having a broad median groove on the upper surface of the thallus. But A. arvensis is a smaller plant, more glaucous in appearance, and its spores are smaller and more regularly reticulated on the plane faces. 6. NARDIA SCALARIS (Schrad.) S. F. Gray, Nat. Arr.

Although Nardia scalaris is so abundant in northern Europe, only a few records of its occurrence in North America have been published. The writer is now able to cite the following localities for the species, several of which have already been noted elsewhere: ! Greenland, according to C. Jensen; Battle Harbor, Labrador, and Lantern Cove, Newfoundland (W'aghorne); Arichat, Cape Breton, Nova Scotia (0. D. Allen); Campobello Island, New Brunswick (Farlow); Dawson, Yukon (Williams); Yes Bay, Alaska (Howell); Juneau, Alaska (Brewer and Coe); Nanaimo, British Colum- bia (J. Macoun); Port Renfrew, British Columbia (Mss Gibbs); Mt. Ranier, Washington (0. D. Allen, Foster, Flett); Olympic Moun- tains, Washington (Frye). The specimens from Nova Scotia and New Brunswick grew on low cliffs by the sea, and those from, Eastport were collected in a similar habitat. The plants formed dense mats, scarcely ten feet above high water mark and only a few feet below the edge of the woods. The species is dioicous and most of the material from North America is completely sterile. The shoots are normally prostrate but become suberect when growing in compact masses. On account of their rotund undivided leaves, usually imbricated and concave, the plants bear a considerable resemblance to such species as N. crenulata and Jungermannia sphaerocarpa. They can be at once distinguished, how- ever, by their small but persistent underleaves, which are lanceolate or subulate in form and taper out to slender points. These under- leaves show clearly, even when a shoot is viewed from one side, be- cause they are not closely appressed to the stem but spread out from it at the base almost at right angles. "The leaf-cells have small but distinct trigones and each encloses a small number of large and glistening oil-bodies with a smooth surface. ‘These peculiarities will also assist in distinguishing the species. The closest relative of N. scalaris is N. Geoscyphus (DeNot.) Lindb., known in New England from New Hampshire and Massachusetts.? This species being paroicous is frequently fertile. ‘The plants rarely occur in dense mats, so that the shoots are usually prostrate and 1 See especially Macoun, Cat. Canadian Pl. 7: 12. 1902. 2 See Evans, Ruopora 9: 57. 1907. 1912] Evans,— Notes on New England Hepaticae,— IX 13 closely adherent to the soil. The leaves, although sometimes undi- vided, are often bifid, and in the variety insecta most of the leaves show the bifid character. The underleaves, although present, are often short-lived and difficult to demonstrate. The trigones in the leaf-cells are usually smaller than in N. scalaris and the oil-bodies are less conspicuous on account of their granular surface. Unfor- tunately in both species the oil-bodies lose their peculiarities in old material, and sometimes disappear completely from specimens which have been long preserved. 7.

Maine: Upper Wilson Pond, near Greenville, Maine (A. W. E. 1911). New Hampshire: Lower Greeley Pond, Waterville (Miss Lorenz, 1908). Specimens from Scoresby Sound, Greenland, collected by N. Hartz in 1892 and listed by C. Jensen ! as O. denudatum, also belong here. The species like- wise occurs mixed with the type material of O. Macounii, collected in 1869 by Macoun in the Lake Superior region of Ontario. Lind- berg's variety elongatum was based on a series of specimens from Iceland, Lapland, and Finland. Among these was one collected by Angstrém at Lycksele in Lapland and distributed by Gottsche and Rabenhorst, under the name Sphagnoecetis communis, in their Hep. Europ. 440. This specimen, which agrees fully with the American specimens noted above, may be considered the type of O. elongatum. According to published records the species grows also in northern Germany;? in the Faroe Islands,’ in Scotland,* and in Austria. One of the Austrian specimens cited was collected by Breidler near Mitten- dorf in Styria and distributed in Flora Exsic. Austro-Hungarica 2340. Unfortunately this plant (of which the writer owes an example to the kindness of Miss Haynes) does not agree with Lindberg's type and should not be included under O. elongatum. The other Austrian specimens reported should therefore be further investigated. Although O. elongatum sometimes grows mixed with Sphagnum and other bryophytes, it often forms large mats which are free from admixture. The type specimen is associated with Lophozia inflata 1 Meddel. om Grønland 15: 369. 1898. ? Warnstorf, Kryptogamenfl. der Mark Brandenburg 1: 238. 1902. 3 C.

Howe, and it is interesting to note that the same species occurs in connection with the material from New Hampshire. The color of O. elongatum is sometimes a bright green, but a yellowish or brownish pigmentation is usually present and a deep blackish purple hue is not uncommon. The shoots at first produce branches very sparingly, and the long unbranched ascending axes are a striking feature of the species. As the stems become prostrate with their increase in length, branches of the usual intercalary kind are pro- duced, some lateral in position and some ventral. Among the latter, as in other members of the genus, a few show a flagelliform char- acter and grow downward, holding the plant firmly in place. Except on these specialized branches rhizoids are sparingly developed. The orbicular leaves, which usually measure 0.5-0.7 mm. in diame- ter, are sometimes distant but more frequently contiguous or imbri- cated. In most cases they are distinctly concave. "The leaf-cells average about 20 u along the margin and about 23 u in the median and basal portions of the leaf. The marginal cells sometimes form an indistinct border, but the texture of the leaves is usually uniform throughout. When the trigones are well developed they are orbicular and project into the cell-cavities; when poorly developed they may be triangular with concave sides. Lindberg considered his variety elongatum poorly supplied with underleaves, but they are really better developed than in most spe- cles of Odontoschisma and often acquire a size of 0.2 X 0.15 mm. They are not very definite in outline but tend to be ovate from a broad base. In some cases they may be shortly bidentate at the apex but this condition is far from constant; occasionally an indis- tinct lateral tooth is present. Slime papillae are unusually abundant; they occur not only along the margin but also on the surfaces, being especially numerous on the upper or inner surface. "The writer! has already called attention to the constant presence of underleaves in Odontoschisma and has emphasized the fact that they yield specific characters of importance. Unfortunately, on account of their fragility, they are often overlooked. A clear idea of them can be readily obtained by dissecting off the tip of a vigorous shoot, mount- ing it in the usual way, and then crushing it by a gentle rubbing pressure on the cover-glass. In this way the underleaves can be separated from the other parts and examined by themselves. Since 1 Bot. Gaz. 36: 330. 1903. 1912] Evans,— Notes on New England Hepaticae,— IX 15 they acquire their characteristics while still close to the growing point, the underleaves secured in this way will give a better idea of their true structure than the weathered underleaves dissected from the older parts of a shoot. The male plants of O. elongatum have not yet been observed, but the inflorescence is evidently dioicous. The female branches are sometimes ventral and sometimes lateral. 'They are usually very short but are occasionally somewhat elongated. "Their leaves, how- ever, are always more or less modified. The bracts proper are in two or three pairs. "Those next the perianth, which are of course the most characteristic, are typically ovate and bifid for one third to one half their length, showing a narrow sinus and acute lobes. Their margins are irregularly crenate or dentate, and sometimes one or two basal lobes or divisions are present. The corresponding bracteole is much like the bracts, except that its divisions are blunter and less definite. Deviations from these typical conditions are not infre- quent, the lobes of the bracts being sometimes short and blunt and the bracteole sometimes showing little or no indication of an apical sinus. 'The tendency to vary in this way becomes even more ap- parent in the other bracts and bracteoles, several of which may be quite undivided at the apex. Unfortunately mature perianths of O. elongatum. are still unknown. In the very immature perianths found in unfertilized flowers the mouth is slightly and irregularly lobed and the margin is finely crenulate from projecting cells. "These peculi- arities doubtless persist until maturity. Gemmae are comparatively rare in the present species, and many tufts fail to show them altogether. The gemmiparous shoots are suberect and much resemble those of O. denudatum, except that they are usually shorter, the development of the gemmae leading more rapidly to the limitation of their growth. In most cases the transition between normal leaves and gemmiparous leaves is very abrupt, but it is sometimes more gradual and a few cases have been observed in which a shoot recovered from the tendency to form gem- mae and developed new normal leaves. The gemmae themselves, which measure about 25 X 33 y, are oval, two-celled bodies with delicate walls. One of the closest allies of O. elongatum is O. Macounii (Aust.) Underw., and it is possible that Austin did not distinguish clearly between them when he published his description of the latter plant. 16 `- Rhodora [JANUARY In commenting upon the type-material of this species the writer ! called attention to the fact that it consisted of an admixture composed of a pale plant with gemmae and a more or less pigmented plant with- out gemmae. It was recommended that the pale material, from which the original description was evidently largely drawn, should be con- sidered the actual type of the species. With regard to the pigmented material judgment was withheld, although the possibility was sug- gested that it might perhaps represent a divergent form of O. Macounii. It now appears, as noted above, that this pigmented material repre- sents 0. elongatum. The species agrees with O. Macounii in its con- cave leaves and relatively large underleaves. Its leaves, however, are less densely imbricated, the leaf-cells have smaller trigones, the slime papillae on the surface of the underleaves are more numerous, the gemmiparous shoots are shorter, their leaves are smaller, and the gemmae themselves have thinner walls. In O. denudatum, which also is closely related, the plants are somewhat more robust than in O. elongatum, and the plants are frequently pigmented with reddish, a type of coloration which the new species apparently never shows. O. denudatum is further distinguished by its smaller underleaves (on shoots with normal leaves), by the absence of surface papillae, and by the more acuminate divisions of the perichaetial bracts. The leaf- cells are much the same in the two species, and the similarity in the gemmiparous shoots has already been mentioned. 8. ANTHOCEROS CRISPULUS (Mont.) Douin, Rev.

Although A. crispulus was included by Nees von Esenbeck among the varieties of 4. punctatus L., he recognized some of its most import- ant characteristics and intimated that it might perhaps represent a distinct species. Douin, however, was apparently the first one to raise it definitely to specific rank. His description and figures were drawn from specimens collected in the department of Eure-et-Loir, in France, and the species has since been reported by C. Müller ? from various scattered localities in Germany. It will probably be found 1 Bot. Gaz. 36: 321. 1903. ? Beih. zum Bot. Centralbl. 222: 253. 1907. 1912] Evans,— Notes on New England Hepaticae,— IX 17 to have a wide distribution in Europe. In addition to the synonyms quoted above Douin gives Anthoceros multifidus L., Sp. Plant. 1140. 1753. If this were actually the same plant the species should of course bear the Linnaean name. 4. multifidus, however, was based upon a non-binomial species of Dillenius, which Lindberg,’ after , examining the type in the Dillenian herbarium, pronounced the same as Riccardia multifida (L.) S. F. Gray (Jungermannia multifida L.). A. multifidus, therefore, becomes reduced to synonymy and the name is not available for future use. The type specimen of Mon- tagne's variety was collected in the Canary Islands, and Douin does not state whether or not he had examined it personally. The differences between A. punctatus and A. crispulus are brought out very clearly by Douin, and the following notes are drawn entirely from his paper. Both the thallus and the capsule yield differential characters. In A. punctatus the thallus is only slightly lobed; in A. crispulus the lobing is much more extensive, the lobes arising from the surface of the thallus as well as from the margin, thus giving it a strongly crispate appearance. In A. punctatus the capsule is from thirty to forty times as long as wide at the time of dehiscence; in A. crispulus it attains a length of from fifty to seventy times the width. In A. punctatus the pseudo-elaters are usually only one or two cells long and apparently never exceed a length of three cells; in A. crispulus, although short pseudo-elaters occur in abundance, much longer ones are also present, some of them being from four to nine cells in length. Both species bear dark colored spores, roughened, especially on the convex face, by numerous sharp or furcate papillae.

YALE UNIVERSITY. NOTES ON THE FLORA OF DUXBURY, MASSACHUSETTS. CLARENCE H. KNow tron. THe Committee which is working on the Flora of the Boston District has had very little information from the southern, and especially the southeastern towns. Except for the Blue Hills and the high land in Sharon and vicinity, this section of country is very flat, rising from sea-level in the east to a height of about 300 feet in Belling- ! See Grout, Bryologist 14: 53. 1911. ? Miss Greenwood reports this species from Worcester (Bryologist 13: 8. 1910), but her record was based on specimens which the writer would refer to C. lunulaefolia. 1912] Knowlton,— Flora of Duxbury, Massachusetts 19 ham, Medway and Holliston, where it merges into the central Massa- chusetts plateau. It is a region of obstructed drainage and sluggish streams, with many ponds, and the waters find their way gradually into the North River, the Taunton and the Charles, which flow east, south and north respectively. The low hills and ridges are naturally covered with oak or pine. Some of the ridges are fertile and pro- ductive, but agriculture seems to find its best land in the meadows. The real interests of the people are in the manufacturing of the larger towns. The people merely occupy the country, without doing over- much to develop it. Thousands of acres are in the broad sand-plains so typical of the section. These and the low glacial knolls are covered with the inevitable Andropogon scoparius and Betula populifolia. The mead- ows seem to be low-lying sand-plains, containing much humus, but little or no clay, and the swamps and ponds are underlaid by water- washed sand and gravel of glacial origin. The swamps are occupied by Acer rubrum or Chamaecyparis thyoides, but many of them, and some of the wetter meadows and shallow ponds have been made over into cranberry bogs. The eastern portion of this sand-plain country, comprising the northern half of Plymouth County, has been very little known botani- cally. It is especially interesting from its proximity to the sea, and because it runs into the big terminal moraine which begins in Kingston and Plymouth. I have made several trips of exploration to Hanson, Halifax and Pembroke, which lie just back from the coast, in this corner of our district, but outside of a few characteristic plants like Solidago Elliottii, S. tenuifolia, Leucothoe racemosa, Ilex opaca, I. glabra, Woodwardia areolata and Aspidium simulatum, the sand- plains and swamps might have been in the Merrimac valley, around Lowell, Tewksbury or Chelmsford, 45 miles further north. When I came to explore Duxbury I expected to find much the same flora, plus the halophytes and xerophytes of salt marsh and sea-beach. In general I found this to be true, for most of the species mentioned above seem to flourish there, but I found in addition enough other plants of interest to warrant this publication. Along the seashore grew some 35 maritime species. Among these may be noted Salicornia ambigua growing freely with S. europaea, S. mucronata, Atriplex arenaria, Suaeda linearis and S. maritima. Xanthium echinatum flourished on the shore edge of the salt-marsh, 20 Rhodora [JANUARY and Hierochloe odorata and Phragmites communis were abundant here as elsewhere along the South Shore. It was of special interest to find some of these seashore plants extending inland. Prunus maritima fruited heavily this year in the gravelly soil it likes best. It extends inland to Halifax and Hanson, some ten miles, and is equally abundant in the Merrimac valley, 35 miles from the sea. Lechea maritima has an even broader landward range, as I have observed it. Atriplex patula grew lustily on the Duxbury dump, two miles back from the coast, with numerous garden escapes. Salsola Kali flourished in a barnyard, as vigorous as its var. tenuifolia, but still rigid and prickly. Hudsonia tomentosa, Ammophila arenaria and Artemisia caudata also occurred away from the shore. As might be expected in one of the oldest Pilgrim settlements, I found many introduced plants, over 50 species. Most interesting of these was the English oak, Quercus Robur L. It has been set out for shade and ornament at Powder Point and elsewhere in the village, but at South Duxbury it has become thoroughly established and is rapidly spreading. In the triangle of wild land between the railroad and the old graveyard where Myles Standish lies buried I discovered a large number of these trees, of all sizes, with much fruit. So far as I know this tree has never become established elsewhere in America. It may be distinguished by its rosettes of round-lobed, crinkly-edged leaves, and its large pedicellate fruit, the acorn five times the height of the cup. Another very conspicuous introduced plant, from the West, Oxybaphus nyctagineus, was abundant and widely scattered over the settled part of the town. Other pilgrims from abroad were Artemisia Stelleriana, Populus alba, Berteroa incana, and Dianthus plumarius. There were but a few plants of the last growing in a railroad cut very near the John Alden house. I observed exactly 50 species of Gramineae, a:few of which deserve mention. Sporobolus asper was in perfect condition on Sept. 24, the dark spikelets fully developed, and well emerged from the upper sheath. Paspalum setaceum was easily distinguishable from P. Muh- _lenbergii by its hairy sheaths and bright blue-green foliage. I have also found these two at Halifax, Plymouth and West Barnstable. Aristida purpurascens and Calamagrostis cinnoides I found each at one place only. : Andropogon glomeratus was abundant in a wet meadow. Agrostis perennans here, as elsewhere, was a characteristic plant of the dry oak woods. 1912] Knowlton,— Flora of Duxbury, Massachusetts 21 My visits to Duxbury have been late for Carex, but on Sept. 10, in a cleared Chamaecyparis swamp, I found Carex trisperma, var. Billingsi, and splendid fresh green plants of C. bullata, var. Greenii, growing in sphagnum moss. I have noticed seven other common species in the township. Along the mucky shore of Cranberry Pond grew a form of Scirpus cyperinus, with cylindrical spikelets, 8 mm. long, which proved to be var. Andrewsii. The type is abundant. The *South Shore," so-called, including the coast towns from Boston to Plymouth, is a veritable paradise for shrubs and woody vines. The numerous forms of Vaccinium corymbosum, Cephalanthus occidentalis in all shapes and sizes, Rhododendron viscosum, Clethra alnifolia, Ilex verticillata, I. glabra and I. laevigata, and Nemopanthus fascicularis are typical shrubs of the swampy woods, and were all flourishing in Duxbury. Ilex opaca I have not yet found, but as it is frequent in near-by towns, and ranges as far southeast as Sandwich on Cape Cod, it is to be expected almost anywhere in moist woods.! Leucothoe racemosa is also a well-distributed shrub in the region, and I found a little of it in Duxbury. Psedera quinquefolia, Smilax rotundifolia and S. glauca were frequent, the last species in the open, in dryer soil than its congener. The only alder was Alnus rugosa, the only grape Vitis Labrusca. Rhus was well represented by R. typhina, R. glabra, R. copallina, R. Vernix and R. Toxicodendron (the creeping form). Solidago Elliottii grew very abundantly in swamps and moist soil generally, and it is a typical plant of the region. In many ways it is our handsomest species, its large dark green foliage forming a pleasing contrast to the clear yellow flowers. I found a little of S. tenuifolia, and a great deal of S. odora, already past blooming on Sept. 10. Aster spectabilis grew well in dry gravelly woods, but A. laevis seemed to be absolutely missing from the flora. Hieracium Gronovii was frequent in dry soil, H. venosum with green leaves was common, but I only found one plant of H. canadense and none of the other species. Asclepias amplexicaule occurred here and there on the sand-plains in some abundance. One sterile shoot I collected because it bore three whorls of three leaves each. Galium pilosum, Gentiana crinita, Poly- gonella articulata and Polygonum arifolium deserve passing mention. 1 As the Pilgrims found '' holly ” on their first exploring trip from Provincetown, in November, 1620, it is reasonable to suppose that this tree had a wider range on Cape Cod, originally. 22 Rhodora [JANUARY Last, and in size surely least, was Lemma perpusilla, which covered the surface of a small and treacherous kettle-hole pond in a pasture. This species is credited to “Massachusetts (Clark)” without further data, in Thompson’s monograph on Lemnaceae. There are no other records given from New England. The indefinite printed record is thus confirmed and made definite, and a new species added to the Local Flora list. Prof. M. L. Fernald collected specimens of this plant in Barrington, R. I., May 30, 1911, on the New England Botani- cal Club Field Day, thus adding a new species to the Rhode Island Flora. In closing it may be well to call attention to the conspicuous lack of native Leguminosae. Aside from Lathyrus maritimus, the only species I noticed were Baptisia tinctoria, Lespedeza Nultallii, L. hirta and L. capitata. In general, the flora of Duxbury is that of seashore and sand-plain, with oak and pine woods, red maple and Chamaecyparis swamps. There are many wanderers northward from Plymouth and Cape Cod, but yet the flora is decidedly different from that of the morainal region and warmer shores only a few miles south. HiNGHAM, MASSACHUSETTS. A Seconp STATION FOR CYPERUS Gmavim IN Essex County, MASSACHUSETTS.— When the Committee on the Local Flora reported in February, 1911, upon the occurrence of Cyperus in the Boston District, C. Grayüi was known within the area only from Plum Island and "never reported at any other station north of Plymouth." It may therefore interest students of our local flora to know that the species occurs upon the sand dunes at Ipswicb. While crossing the dunes with a party of students upon October 12th, I found a single small colony of not more than half a dozen plants. They had all fruited well and most of the achenes had fallen, so that the colony (presumably of recent derivation from Plum Island) is likely to in- crease. A specimen was taken for the Club Herbarium and another was collected by Mr. Harold St. John.— M. L. FERNALD, Gray Herbarium. REGARDING VIOLA PEDATA, FORMA ROSEA.— Miss Sanders’s report of this plant from Wayland, Mass. (Ruopora, xiii. 172) leads me to 1912] Fernald,— Sclerolepis uniflora in Massachusetts 23 state my experiences with it. Occasionally during several years past I have found on a sandplain in Framingham where the bird’s-fc ot violet occurs in great abundance plants bearing flowers varying in color from a light to a deep magenta, or almost red. Though the positicn of these individuals was carefully noted, I have never been able to find flowers of the same color in the same spot the succeeding season. Finally two of the unusual plants were transplanted to a garden. A year later these very plants bore the usual lilac-purple flowers. The cause of my inability to rediscover these reddish flowers at their old stations was thus suggested, and I uprooted the fickle things. A similar experience befell me with Rudbeckia hirta. In July 1910 a specimen of this handsome weed was noticed differing from the thousands of others about it on a dry hillside in that the proximal half of each ray was a deep brownish-purple, somewhat brighter than the disk. It was carefully transplanted to good garden soil. But prosperity ruined it, too; this summer’s flowers were plebeian in every way. Hence it suffered the fate of the violets. It seems, therefore, that in these two cases, weak or pathological conditions are *esponsible for the color forms, the death or recovery of the abnormal individuals making their rediscovery impossible.— A. J. EAMES, Cambridge, Massachusetts. SCLEROLEPIS UNIFLORA IN MassACHUSETTS.— On the 29th of October, 1909, Messrs. J.-F. Collins, Thomas Hcpe and H. W. Preston found the unique little pine barren Composite, Sclerolepis, on the shores of Wallum Pond in Burrillville, Rhode Island,! the only station in New England except Dr. Lewis's at Bradford, New Hampshire.? Having occasion recently to look up the location of Wallum Pond, the writer was interested to note that it lies partly within the town of Douglas in Worcester County, Massachusetts; and since the Com- mittee on the Massachusetts Flora had nc record of Sclerolepis from the state it seemed worth while to settle whether the plant is as localized (found only in Rhode Island) as might be inferred from Pro- fessor Collins's note. Accordingly plans were made to visit the pond with Mr. F. F. Forbes on October 29 last — on which date in 1909 the 1 Collins, Ruopora, xii. 13 (1910). ? F. T. Lewis, RHuoponza, vii. 186 (1005). 24 Rhodora [JANUARY plant was “just coming into bloom.” We had expected to go from Brookline to Douglas by automobile, but the freezing weather of the preceding night rendered a motor trip somewhat unattractive, so we went by train and drove from the station in Douglas to the northern end of the pond. All the vegetation of the sandy beach was blackened by frost, but searching on our hands and knees among the shriveled remnants of Feria, Ilysanthes, etc. we soon found a dried and fruiting plant of Sclerolepis within a stone's throw of the northern end of the pond — about one mile north of the Rhode Island line. Prolonged search revealed no more of the plant on the dry beach, but after giving up the hunt and starting upon a circuit of the pond we were delighted to find Sclerolepis green and in all stages of development from young bud to mature fruit in a spring-rill (also in Massachusetts) upon the northeastern shore. After tbat little of the plant was found upon the eastern shore, but on making our way over and amongst the granitic boulders which strew the western shore we came upon it in great quantity at every spring and seepy bank among the boulders. Such stations, with Sclerolepis the only green and flowering plant at this late date, were found at frequent intervals along the entire length of the western shore, in both Rhode Island and Massachusetts. "The point which struck us was that, although abundant in and around springs and often completely submersed, Sclerolepis was nowhere seen in rapidly flowing streams. 'The abundance of the plant about Wallum Pond, which is a clear sheet of water with a clean beach of granitic gravel and sand, suggests the probability that search about other such ponds — which are numerous — in Worcester County and the eastern section of Massa- chusetts as well as in eastern Connecticut, will show Sclerolepis to be more generally distributed than we know. It is highly probable that the late flowering season of the plant — after most plants of such shores are past maturity — has -prevented its detection, but from our experience at Wallum Pond we should advise watching for the plant in September and early October. Superficially Sclerolepis suggests the Mare's Tail, Hippuris vulgaris, or a very attenuated Aster nemoralis with tiny flesh-cclored heads.— M. L. FERNALD.

THE POND FLORA OF CAPE COD. Epmunp W. SINNOTT. Tue flora of Cape Cod presents many features of interest to the botanist, for it includes scores of plants which are unknown or rare on the rest of the mainland of Massachusetts and which find their best development on the sandy soil of the coastal plain. Botanizing anywhere on the peninsula is consequently attended, at least to the new-comer, by the formation of many new acquaintances among the plants of the beaches, the salt-marshes, the barrens and the swamps, which have each their distinct vegetation and their particular interest. Perhaps the most fascinating collecting-ground for the field botanist, however, is furnished by the hundreds of ponds scattered everywhere over the Cape. These range in size from the tiny sloughs in every hollow to such large lakes as Wakeby Pond in Mashpee, Nine-Mile Pond in Barnstable and Pleasant Lake and Long Pond in Harwich. It is in the waters and along the shores of these ponds that are found many of the characteristic coastal-plain plants which here reach their northern limit in the United States. During the past five summers the writer has been fortunate enough to visit nearly all the large ponds on Cape Cod and many of the smaller ones in almost every town of Barnstable County. The object of the present paper is to record certain observations as to the general character of the pond vegetation and as to the distribution of the various plants of which it is composed. The ponds of Cape Cod fall naturally into two main groups: those which are well drained and have practically the same level throughout the year, and which include all mill-ponds, herring-ponds and others 26 Rhodora [FEBRUARY from which streams are continuously flowing; and those which have poor drainage or none at all. To the latter group belong the great majority of the small ponds as well as most of the larger ones. The vegetation along the shores of the well-drained ponds is not distinctive and is very much like that found in similar situations throughout southeastern New England, save that it is somewhat less luxuriant. Wide sandy shores are, of course, absent. Where the bottom shelves off deeply and the banks are at all precipitous, the pine and oak flora of the barrens comes down to the water’s edge and the sandy or pebbly bottom near the shore will support only such plants as Nymphoides lacunosum, Lobelia Dortmanna and Scirpus americanus. In the majority of cases, however, the slope of the shore-line is much more gradual, and allows the accumulation of a considerable deposit of mud and silt, which forms a congenial habitat for a large group of plants, of which Pontederia cordata and Decodon verticellatus are per- haps the most characteristic. These are found along the shores of all ponds whose water-level is approximately stable, and with them are such familiar things as Typha latifolia, T. angustifolia, Spar- ganium americanum var. androcladum, Sagittaria latifolia, Scirpus validus, Acorus Calamus, Impatiens biflora, Ludvigia palustris, Ascle- pias incarnata var. pulchra, Bidens connata and very many others, which form the dense and (for the Cape) luxuriant vegetation of such pond-shores. In the water flourish Castalia odorata, Nymphaea advena, Myriophyllum humile, various species of Potamogeton, notably P. Robbinsii, and other equally familiar plants. This general group of mud-loving things, particularly Sparganium americanum var. androcladum and Sagittaria latifolia are also characteristic of cran- berry-bog ditches and sloughs wherever alluvial mud has been de- posited. This whole mud flora is practically identical with that of similar situations throughout southeastern New England but com- prises a very different group of plants from those growing on the peaty mud of the undrained ponds in the sand-barrens. The ponds where drainage is incomplete or absent constitute the great majority of all the bodies of water on Cape Cod, and have associ- ated with them a large and distinctive flora. The water-level here is subject to great fluctuations, and the surrounding dry-ground vege- tation is consequently forced to stop at the extreme high-water mark, with the result that in the summer months, when all the ponds are apt to be rather low, a sandy beach extends for some distance upwards 1912] Sinnott,— Pond Flora of Cape Cod 27 from the water’s edge. In ponds with absolutely no outlet, the rise and fall of the water is greatest, and the beach here is of considerable width, but in many cases the pond overflows into a drainage-brook at a little above its normal summer height and is consequently sur- rounded at that season by only a narrow belt of sandy shore. This is the case with most of the large lakes. The character and extent of the vegetation on these beaches and in the shallow water at the pond-edge vary considerably from one pond to another and seem to be under the control of several different factors. Small ponds, in general, show a much more luxuriant plant-growth around their shores than do larger ones, which are apt to have long stretches of pure sand or gravel beach and bottom, practically devoid of vegetation. This may well be explained by the fact that the wave- action, which is much more vigorous on extensive sheets of water than on smaller ones, has in these larger ponds pretty thoroughly washed out all the mud and fine material in the sand, and left it in much the condition of a barren sea-beach. It is also conceivable that in the winter and spring, when the water is usually highest and storms are most frequent, the waves should wash out and destroy seeds and young plants which had found lodgment along the shore. It is noticeable that wherever the soil next the shore has been disturbed and broken up, as by a cutting or a road, the waves have spread the sand up and down the beach for a considerable distance, to the practical exclusion of all vegetation. These same sterile sandy beaches are also occa- sionally found on small ponds, but in such cases a good depth of water and an abruptly sloping bottom are always observable. Wherever conditions are favorable, therefore, for washing out fine material of all kinds from the shores and depositing on the bottom, a sterile beach of pure sand and gravel will result. Most of the smaller ponds, which are protected by their size from violent wave action, have bottoms sloping gently to no great depth and consequently both the beaches and the shallow shores are well able to support a considerable vegetation. It is also noticeable that on the same pond such portions of the shoreline as are most exposed to the waves or which have especially steep slopes are much less thickly covered with plants than are the protected stretches, and that the coves or sheltered places always show a more luxuriant vegetation than do the open straight beaches. 28 Rhodora [FEBRUARY This condition has had an important influence on the process of filling which has been going on since the ponds were left at the retreat of the ice-sheet. Their original shape seems in most cases to have been decidedly irregular, for every pond of any size has along its shore a number of indentations in all stages of filling, from shallow pools with thickly covered shores to peat-filled swamp-holes. These are cut off from the rest of the pond, at least in their later stages, by a barrier of sandy beach, and simply represent small arms of the original pond which from their sheltered position have filled rapidly and been con- stricted off from the main body of water. The tendency is always for a pond to smooth off its shores, thus approaching more and more to a roughly circular shape, and for the large, and especially the long and narrow ponds to become divided up into a number of smaller ones, each of which centers about some particularly broad and deep portion of the original. The flora of the pond-shores is varied and, as has been said, contains many characteristic Cape Cod plants which from their distribution are worthy of note. The upper edge of the beach is dry sand or gravel in summer and is apt to be invaded by herbaceous members of the surrounding sand- barren flora. Here Aletris farinosa, Polygala polygama, Cassia nictitans, Linum virginianum, Chrysopsis falcata and many other common things find a congenial habitat. The plants of the lower parts of the beach, however, whose roots are in damp sand, form a distinct group, the members of which occur in practically no other situation. A list of the commonest and most characteristic beach plants, which would be found along almost every undrained pond of any size on Cape Cod, includes the following:— Lycopodium inundatum var. Bigelovii, on damp sand and also on peaty mud. Cyperus diandrus, universal and usually the first plant to gain a foothold on the sterile portions of the beach. Rynchospora glomerata. Xyris caroliniana. Polygonum Careyt. Hypericum virginicum and Gratiola aurea, extremely common everywhere and flourishing equally well on sand or mud. Hypericum canadense. Rhexia virginica. 1912] Sinnott,— Pond Flora of Cape Cod 29 Lysimachia terrestris. Sabatia dodecandra, a beautiful flower and one of the glories of the Cape. It is apparently absent below Eastham. Drosera filiformis, flourishing everywhere and sometimes attaining a height of 18 inches. Drosera longifolia, Polygala cruciata. Stachys hyssopifolia, abundant on the upper Cape but rare beyond Brewster. Lycopus sessilifolius. Gerardia purpurea. Coreopsis rosea, extremely abundant. Solidago tenuifolia, characteristic of dry sandy soil all over the Cape, yet thriving on the damp sand of every pond-shore. These are all very common and universally distributed, but there are many others the occurrence of which is less general or which are rare and local. Such plants are, — Panicum Wrightianum Scribn., common on the middle Cape. This species, based upon Cuban collections of Charles Wright's, was un- known in the northern states at the date of issue of the 7th edition of Gray's Manual; but it was collected on Cape May, New Jersey, in 1909 by Mr. Witmer Stone and its discovery as a common grass on Cape Cod makes a striking addition to our “pine barren” flora. The material was determined by Mrs. Agnes Chase. Scleria reticularis and Fuirena squarrosa, rare, collected by the writer only from the “ Mary Dunn’s”’ Ponds in Barnstable. Rynchospora macrostachya, rather common. Hemicarpha micrantha, easily overlooked but probably pretty common. It prefers pure sand. Fimbristylis Frankii, occasional. Eleocharis melanocarpa. On a few ponds. Carex of several species, notablv C. lurida, but C. albolutescens, C. hormathodes and others are often present. Xyris flexuosa, rather common. Lachnanthes tinctoria, abundant on many ponds but often lacking especially on the lower Cape. Drosera rotundifolia, common on Sphagnum, patches of which are often present on well-covered shores. Crotalaria sagittalis, local, found only on two ponds in Sandwich. 30 Rhodora [FEBRUARY Sabatia gracilis, found by the writer only on a few ponds in the eastern part of Barnstable. Lycopus rubellus, locally common. Utricularia cornuta, rather frequent on sandy shores. It also appears on Sphagnum and occasionally on the edge of brackish marshes. Certain members of this group of beach-plants, such as both species of Sabatia, Drosera filiformis, Hemicarpha and Crotalaria prefer a situation rather well up the beach, where the sand is not too wet, while others, such as Rynchospora macrostachya, Gratiola, Hypericum virginicum, Lysimachia terrestris and Lycopodium choose lower and damper locations, and usually appear only after a perceptible amount of fine material has accumulated. Most of the plants, however, are satisfied with almost any situation where the soil is essentially sandy and not too dry. They must of necessity be able to adapt themselves to the migrating shoreline. The nature of the vegetation in the shallow water along the shore depends on the character of the pond and the amount of filling and of deposition of mud that has taken place. On a bottom of pure sand the first thing to make its appearance is Nymphoides lacunosum which usually grows in a rather narrow zone at some distance from the shore. Nearer the water’s edge flourishes Juncus militaris, the most common and characteristic rush of the sandy ponds, and growing with it and nearly as universal is Lobelia Dortmanna. Scirpus americanus is always present, either scatteringly or in wide patches. These four plants prefer a sandy bottom and until sediment begins to accumulate comprise practically all the marginal vegetation. The deposition of decaying plant remains and the formation of peat accompany the filling of these ponds and the fine material is in this instance different from the more or less alluvial mud of the drained ponds and supports quite another group of plants. The most char- acteristic things associated with these later stages in the pond’s history and which flourish only in the calm and shallow waters of the protected coves, or on their peaty shores and islands, are the following: — Sparganium lucidum, local, and found by the writer only in Barn- stable. Sagittaria Engelmanniana, very common everywhere and showing great variety in the shape of its leaves. 1912] Sinnott,— Pond Flora of Cape Cod 3l S. teres, probably rather common but found by the writer only in Sandwich, Barnstable, Yarmouth and Wellfleet. In shallow water and where the bottom is sandy it has short and stout phyllodes, but more commonly they are long and tapering. Eleocharis acicularis, on peaty shores everywhere. E. Robbinsii, the dominant plant in very shallow, peaty ponds, gradually encroaching from the shore and finally converting the whole pond into a grassy swamp. Cladium mariscoides, common on many ponds but often absent. Dulichium arundinaceum, abundant and delighting in the thick vegetation along the peaty shores. Rynchospora alba, locally common on peat. Eriocaulon septangulare, on muddy bottoms in shallow water everywhere. Xyris Smalliana, a striking species, usually confined to floating masses of peat, and fairly common where they are present. The writer has observed it in Barnstable, Harwich and Wellfleet. Juncus pelocarpus, common everywhere, but exceedingly abundant on certain ponds where there is a rather pebbly bottom and not much mud. It also thrives well above the water-mark. J. canadensis, often abundant at the water's edge. J. marginatus, rather common. Proserpinaca pectinata, locally common on mud. P. palustris, rare, found only an Snake pond in Sandwich. Myriophyllum tenellum, fairly common. Utricularia vulgaris var. americana, occasional. U. purpurea, common on muddy bottoms. U. biflora, rare, on sandier shores. Castalia and Pontederia are often present, and in the last stages of filling, when the pond has become a bog, other plants appear, which are more characteristic of the half-drained and muddy swamps. These are Sparganium americanum var. androclodum, Sagittaria latifolia, Cyperus dentatus, Eriophorum virginicum, Nymphaea advena, Bras- enia Schreberi, Sium cicutaefolium and many others. It will therefore be apparent that, as might be expected, a large percentage of the flora of the undrained sandy and peaty ponds, where conditions are very similar to those on Long Island and New Jersey, is composed ,of plants whose distribution is confined to the Atlantic coastal plain and its extensions. 32 Rhodora [FEBRUARY The distribution of the pond-plants, in common with that of the rest of the flora, is influenced to a considerable extent by the topog- raphy of Cape Cod. The “backbone of the Cape" is formed by two fan-shaped terminal moraines, one of them of rather low hills running north and south along the eastern shore of Buzzard’s Bay and string- ing out into the Elizabeth Islands; and the other, with slightly higher elevations, which sometimes reach nearly 300 feet, extending east and west down the north shore of the main body of the Cape. East and south of these moraines, respectively, the country is mostly barren sand-plain from the soil of which practically all the fine material was washed by the waters flowing from the glacial ice-front; while on the narrow strips of land on the other side of the hills, in each case, and between them and the water, the country is much more fertile. This is particularly noticeable on the north shore of the Cape, in the northern parts of the towns of Sandwich, Barnstable, Yarmouth and Dennis, where there is considerable clay in the soil, deposited on the bottom of a dammed-up glacial lake or scooped up by the ice-sheet from the bottom of the bay. In these richer strips muddy drained ponds and alluvial swamps are conspicuous, while the typical sandy ponds, with their coastal-plain vegetation, are practically confined to the above-mentioned barrens and to the very sandy “forearm,” from Chatham to Provincetown. Although conditions are very similar throughout these sandier parts of the peninsula, the pond flora, in common with the rest of the vegeta- tion, grows less varied as one goes eastward " down" the Cape. Of course the commonest and most characteristic plants (with one or two exceptions, such as Stachys hyssopifolia, which apparently does not occur below Brewster) are nearly universal in their distribution, but many of the less common things stop somewhere on the upper (west- ern) part of the Cape. Sabatia dodecandra, for example, gets as far as Eastham, but the smaller species, S. gracilis, together with such plants as Scleria reticularis and Fuirena squarrosa reach their eastern limit on the group of small ponds near the Barnstable-Yarmouth line. Crotolaria, in the same way, does not come east of the town of Sand- wich. This central part of the Cape, including the towns of Sandwich, Barnstable and Yarmouth, has by far the richest pond-flora in the county. Snake, Peter’s, Triangle and Spectacle Ponds, in Sandwich have wide sandy beaches and a large flora which, together with their 1912] Sinnott,— Pond Flora of Cape Cod 33 comparative inaccessibility, makes them a fascinating collecting- ground. Wakeby Lake (really in Mashpee) with the Cotuit Ponds and Great Nine-Mile Pond, in Barnstable, are all partially drained and have narrow gravelly beaches for the most part, which are often un- interesting, though in certain spots there is excellent collecting. Perhaps the richest flora of all, however, is found on the “Mary Dunn" Ponds near the eastern border of Barnstable township. There are a score or more of these, of all sizes and in all stages of filling, and a number of plants grow here which the writer has found nowhere else on the Cape. In Yarmouth, also, there are many interesting collecting-places, notably Dennis, Miller, Greenough and other smaller ponds in the northern part of the town and Sandy, Basslot, Flax and others nearer the south shore. Of course the ponds of the lower Cape, such as those about Pleasant Lake in Brewster and near the villages of Eastham and Wellfleet, have a large and varied flora, as have the ponds in the Falmouth region, to the west, but many plants are rare or absent there which occur commonly in the Barnstable area. The often sporadic and local distribution of many Cape plants would conform to what one might naturally expect of the behavior of a previously more extended coastal plain flora which is gradually dying out, and, from other evidence, it seems very possible that something like this is happening. On the other hand, the fact that vegetation both to the eastward and to the westward of the above- mentioned central region is progressively less and less rich in coastal- plain plants makes it reasonable to suppose that we have here a center of distribution for these things, which have come north not along the southern coast of Connecticut and Rhode Island, probably, for they are rare or absent there, but through Long Island, across to Martha’s Vineyard and Nantucket and thence across Vineyard Sound to the mainland of Cape Cod. Their distribution here perhaps marks out roughly the position of an arm of the ancient coastal plain. The whole question is of great interest in connection with Professor Fernald’s discovery of a large coastal plain flora in Nova Scotia and Newfoundland, but more data must be gathered before any very definite conclusions can be drawn in regard to the origin of the flora of Cape Cod. The foregoing paper does not pretend to give a complete account of the pond vegetation of Cape Cod, but the writer has attempted to 34 Rhodora [FEBRUARY enumerate merely the common and distinctive members of the pond flora, together with such of the more rare plants as have come within his experience, and to set forth certain observations as to their behav- ior and distribution. Much more active collecting must be done on the Cape before we can feel sure that its flora is well known, and there are few regions so near Boston which offer to the field botanist such opportunities for interesting and valuable work. The writer wishes to express his thanks to those who have aided him in gathering data, especially to Mr. William G. Vinal, of the Providence Normal School. CAMBRIDGE, MASSACHUSETTS. QUERCUS IMBRICARIA MICHX. IN MASSACHUSETTS. Gro. G. KENNEDY. SARGENT in his manual of the trees of North America (1905) gives Lehigh county, Pennsylvania, as the northern limit of this species in the Eastern United States and says of it: “occasionally planted as an ornamental tree in the northern states and hardy as far north as Massachusetts"; and in the Sylva, vol. VIII, p. 177, calls it “one of the most beautiful of the American oaks, and a most distinct and desirable ornament of the parks and gardens of eastern America, where it is perfectly hardy as far north at least as the shores of Massa- chusetts Bay.” And yet it appears to be a rare tree in cultivation in this vicinity, two trees only being reported outside the Arnold Arboretum. One of these is near the entrance to the Chestnut Hill Reservoir, and the other close to Brush Hill Road in the town of Milton. Prof. Sargent informs me that he has had two plantings of this species in the Arboretum: one in 1873, and one in 1887, and both from Meehan of Philadelphia. The Reservoir tree is of the 1873 planting and was sent with other oaks from the Arboretum to be set in the Boulevard adjacent to the Reservoir. There are several fine trees of the 1873 planting in the Arboretum; the best one is growing near the Motley house. This tree has a girth of 47 inches at three 1912] Fernald and Wiegand,— Juncus balticus 35 feet from the ground, a height of about 45 feet and a spread of 50 feet. The Reservoir tree has a girth of 57 inches, a height of about 40 feet and a spread of 45 feet. The Milton tree has a girth of 51 inches, a height of about 40 feet and a spread of 41 feet. These trees are apparently near enough together in size to belong to the same planting; but to account for the Milton tree being where it is, has puzzled many who recognized it as a stranger. It stands in an open pasture about two feet from the street wall and was exposed to public view in October, 1900, after severe roadside cutting and removal of Viburnum and other shrubs by the Superintendent of streets and his men. No trees have been planted along this wall for at least thirty-three years to my certain knowledge, and I believe the field has been an open pasture for many years longer. To explain its presence on this Massachusetts highway the story has gained credence that it sprang from an acorn thrown into the field by a soldier just returned from the South. Readville camping ground is a half mile away and regiments returning from the war were often quartered here for weeks before discharge. The probable age and general appearance of the tree and its surroundings lend color to this invented story. No one imagines that the tree was planted by the hand of man. It bears fruit pretty regularly, but no one has seen any seedlings in the vicinity. 'The very persistent foliage makes it a conspicuous tree in the late fall and winter: it is green till almost Christmas and its last leaves have not fallen by the first of March. It is certainly “a distinct and desirable ornament" of the country roadside and as it is owned by a lover of trees we may hope it will be carefully guarded for another century.

L. FERNALD and K. M. WIEGAND. SOME PANICUMS OF ESSEX COUNTY, MASSACHUSETTS. F. Tracy HUBBARD. Durine this autumn’s collecting of Gramineae and Cyperaceae in and about Manchester, Massachusetts, several interesting species of the genus Panicum were found. Among these there are several, at present, rather rare species; one in particular, P. lucidum Ashe,/ which has not been reported from the state. Several others are range- extensions and many of them do not seem to have been reported from Essex County. The following species are the more noteworthy. Panicum LUCIDUM Ashe. Hitchcock and Chase, North American Species of Panicum, do not cite this species from New England, though Mrs. Chase informs me that since the revision of Panicum she has seen specimens from Pomfret, Connecticut, July 4, 1901, A. W. Driggs no. 4 and two collections from Stonington, Connecticut, June 23, 1901, C. H. Bissell no. 5576; L. Andrews, July 13, 1902; the last doubtfully to be referred to this species. There is no specimen of this species from New England in the Gray Herbarium, and it is not represented in the Herbarium of the New England Botanical Club. My specimens are: No. 129a, rich wooded roadside, near 1912] Hubbard,— Panicums of Essex County, Massachusetts 37 Ayer's Pond, Manchester, Sept. 28, 1911 and No. 193, hillside among ledges, West Manchester, Oct. 11, 1911. Specimens of these two numbers were sent to Mrs. Chase of the Bureau of Plant Industry, and determined by her. She writes mé in regard to No. 193 that "specimens from the northern limits of its range do not seem to develop the almost vine-like habit in the autumnal phase, characteristic of the species here and southward, though your 193 is the first late autumnal specimen we have received from New England. We had not seen any from New England when the revision was published. Yours is the northernmost record as yet, and your specimen the nearest typical from New England." From a note on No. 129a Mrs. Chase would seem to lay specific distinction on the comparative conspicuousness of the epidermal cells of the under surface of the blades. PANICUM TENNESSEENSE Ashe. Hitchcock and Chase, l. c., cite this from Massachusetts, Framingham, Smith, nos. 741, 743. Rep- resented in the Gray Herbarium from Massachusetts, Framingham, E. C. Smith, (no number). There are Massachusetts specimens in the Herbarium of the New England Botanical Club from Magnolia, C. H. Clarke; Boston, 1882, Chas. E. Perkins. My specimens were verified by Mrs. Chase and are No. 153, rich wooded roadside, Wen- ham, Oct. 3, 1911; No. 170, rocky wooded hill, Manchester, Oct. 7, 1911, and No. 174, low hollow — prostrate —, Manchester, Oct. 8, 1911. This species has been sparingly reported from Massachusetts and if the Clarke collection is typical, as it seems though unverified, has been previously found,— though apparently not recorded,— in Essex County. As this species is represented in the Gray Herbarium by specimens from New Brunswick, all the New England states and southward, it seems as though careful collecting would show it to be more widely distributed in Massachusetts than it is now known to be. Panicum LANGUIDUM Hitche. & Chase. Hitchcock and Chase, l. c., cite this species in Massachusetts from Ashburnham, Harris, 1896. Not represented from Massachusetts in the Gray Herbarium. In the Herbarium of the New England Botanical Club, Massachusetts, is represented from Ashburnham, July 12, 1896, Sydney Harris (two sheets). My specimen is No. 205, gravelly roadside, West Gloucester, Oct. 13, 1911. A specimen of this number was sent to Mrs. Chase and the deter- mination is here. She writes, “ No. 205 is not typical, the blades being 38 Rhodora [FEBRUARY glabrous above; but such ‘vernal’ culms shooting up in the fall often depart from the usual characters of a species.” This rare species, the type of which was collected by M. L. Fernald in Maine has also been collected from Maine by Parlin and by Fernald at several locations, and from Vermont, Hartland, Ruggles no. 49 (the last on the authority of Mrs. Chase), as well as from Massachusetts, as reported above. The Ashburnham specimens of Harris have a noticeably different habital aspect from the Maine specimens of Fernald and from my No. 205 and the lower branches of the panicle do not have the same marked droop which is so noticeable in Fernald’s Maine specimens and only slightly less marked in my No. 205. However these Harris specimens bear the verification of Hitchcock and Chase as shown by their revision labels and con- sequently must be accepted as correctly named. Seemingly new to Essex County and eastern Massachusetts. Panicum TsUGETORUM Nash. Hitchcock and Chase, l. c., cite from Massachusetts, Framingham, Smith, no. 740. Represented in the Gray Herbarium from Massachusetts, Woburn, M. L. Fernald & E. F. Williams; Framingham, E. C. Smith (no number). In the Herbarium of the New England Botanical Club, Massachusetts, is represented from Boston, 1881, C. E. Perkins; Housatonic, Berk- shire County, 1906, Ralph Hoffmann. My specimens are No. 169, rich open woods, Manchester, Oct. 7, 1911; No. 180, sterile soil, Beverly Farms, Oct. 9, 1911; and No. 187, bushy roadside, Conomo Road, Essex, Oct. 9, 1911. j Specimens of these numbers were sent to Mrs. Chase and deter- mined by her. From her notes, good specific characters would seem to be the long first glume, the short ligule, the short crisp pubescence on culm and sheaths and the thin white margin of the blades. This species is represented in the Gray Herbarium by specimens from Maine, Vermont, Massachusetts as above cited, Connecticut, New York, southward and westward,— hence it should prove more widely distributed in Massachusetts. PANICUM COLUMBIANUM Scribn. Hitchcock and Chase, l. c., cite from Massachusetts, Wellesley, Smith, no. 738; Framingham, Smith, nos. 742, 744. Not represented from New England in the Gray Herbarium. In the Herbarium of the New England Botanical Club there is a Massachusetts specimen from Stoneham, W. P. Rich, no. 343 in part. My specimens are No. 118, ballast of R.R., West 1912] Hubbard,— Panicums of Essex County, Massachusetts 39 Gloucester, Sept. 27, 1911, and No. 166 rich open woods, Manchester, Oct. 7, 1911. Specimens of these numbers were sent to Mrs. Chase and deter- mined by her. Apparently this species is new to Essex County. Other Massachusetts stations have been reported in Rhodora 1: 98 (1899) and 3: 126 (1901). PaNICUM ORICOLA Hitche. & Chase. Hitchcock and Chase, l. c., cite from Massachusetts, Nantucket, Bartlett, no. 1368, 1379, et al.; Plymouth, Oakes; Quanquisset, Bartlett, no. 1327. Represented from Massachusetts in Gray Herbarium from Plymouth, Oakes. In the Herbarium of the New England Botanical Club, Massachusetts, is represented by Eastham, F. S. Collins, nos. 248 & 293; Truro, W. P. Rich; Hyannis, Churchill. My specimen, verified by Mrs. Chase, is No. 158, dunes Ipswich Beach, Ipswich, Oct. 5, 1911. There seems to be no previous record of this species north of Cape Cod, but Mr. M. L. Fernald informs me that he collected it on the Ipswich dunes about a week later than I. Panicum AsHEI Pearson. Hitchcock and Chase, l. c., cite from Massachusetts, Malden, Fernald, 1891, in part; West Quincy, 1894, Churchill. Represented in the Gray Herbarium from Massachusetts, Melrose, W. P.

Williams; Blue Hills, Warren H. Manning; Housatonic, Berkshire County, Ralph Hoffmann. My specimen is No. 194, among bushes, rocky hillside, West Manchester, Oct. 11, 1911. A specimen of this number was sent to and verified by Mrs. Chase. This collection extends the known range of the species slightly north- ward. A complete list of the Panicums collected in Essex County from Sept. 26-Oct. 13, 1911, is as follows. Where there are specimens in the Gray Herbarium or the Herbarium of the New England Botanical Club or where there are published records of the species from Essex County. I have noted the fact.

SYDYN CAMBRIDGE, MASSACHUSETTS. A THIRD STATION IN VERMONT FOR CypERUS HOUGHTONII.— In an article in Ruopona for July, 1903, I told of my discovery of the second station for Cyperus Houghtonii Torr. in Vermont in 1901. Dr. Ezra Brainerd, who identified the plants for me, expressed doubt at the time as to it being native since it occurred but a few rods from a railroad. But during the past season his doubts were removed by the finding by himself of a third station for the plant in Castleton. This last station is so far from a railroad as to make him feel assured that the species is indigenous. It is in the same habitat as the stations spoken of in my article referred to above, dry shifting sand.— NELLIE F. Fiynn, Burlington, Vermont.

X A gentle, unassuming, lovable life came to its earthly close when Frederick W. Batchelder left us. The task of writing a fitting notice of him for a botanical journal is a hard one; for those who knew him, the man is so much more than the botanist, that with a heavy heart and with eyes that scarcely see through tears, the tribute which he well deserves in this magazine is attempted. Frederick W. Batchelder was born in Pelham, N. H., in 1838, son of Dr. Amos Batchelder and Rebecca (Atwood) Batchelder, a descend- ant on his father’s side from the Rev. Stephen Bachiler who came over from England in 1632. In the nearly three centuries which have elapsed since that time, the spelling of the name has undergone many changes, for every branch of the old divine’s posterity seems to have had its own way. The common ancestor of all was excommunicated in his own country for his independent religious opinions, and in this country too, the sturdy and brave old parson was so persecuted for his departure from the ecclesiastical ruts to which he was consti- tutionally averse, even his moral character being assailed, that after some twenty years here, he shook off the dust of New England from his feet, and returned to Old Boston, England, where he died at the age of 100, a man of great vigor physically and intellectually. His character is thoroughly vindicated in our times from the injurious charges which prevailed against it for two centuries. On his mother’s side Mr. Batchelder came down from Hugh Tallant of whom Whittier wrote in “The Sycamores.” The poet gives many verses to him as a story-teller and musician, but Hugh was much more than a “rustic Irish gleeman.” He was a man of great force of char- 42 Rhodora [Marcu acter. Coming a poor immigrant, he soon acquired property in New Hampshire, where he lived as a good citizen, adding to the happiness of all who knew him “with his eyes brimful of laughter, and his mouth as full of song." He came from Ireland, but he was a member of the church of England, and probably from one of the “transplanted ” English families of Cromwell's time. Our friend just lost had his musical gifts in fullest measure, and his gaiety of temperament; would that he might have inherited the vitality of these two ancestors, for Hugh lived through a vigorous old age to be 108. The young Batchelder was fitted for Harvard in the Boston Latin School, and was graduated from college in the "fighting class" of 1860 — the class of whose 146 members 79 went to the war and 19 gave their lives. Mr. Batchelder entered the service as surgeon steward in the navy, on the bark Kingfisher of the South Atlantic blockading squadron, and after thirteen months of service was honor- ably discharged on account of disability. From that time he made Manchester, New Hampshire, his home except for a few years spent in Springfield, Massachusetts. He married, in Manchester, Miss Annie Varney, daughter of the Hon. David Varney of that city. The lifework of the young man was already outlined at his gradua- tion. He had studied medicine under Dr. Oliver Wendell Holmes, and had been a pupil of Agassiz. He became an excellent botanist in after years and also an ornithologist of good standing. His cata- logue of the plants of southern New Hampshire and his editing of - Allen's “Birds of New Hampshire" and Wright's “Birds of the Jefferson region" show what thorough work he could do in both these branches of science. Thoroughness, indeed, was a characteristic of all that he did. Mr. Batchelder was gifted in many ways, but he was, first of all, a musician. As a composer, particularly for the organ, he had high rank; the fine quality and originality of his work were recognized as admirable by the best judges; but his musical and scientific work were both hampered by ill health. For the last fifteen years of his life he worked constantly with more or less suffering, but always per- sistently, cheerfully and with indomitable courage. Neither ill health nor ill fortune could ever shake his beautiful optimism, as prominent and winning a trait as any part of his character. He was an organist for fifty-two years without interruption, from his college 1912] Owen,— Frederick William Batchelder 43 days at Harvard, when he played in Appleton Chapel, to his last ser- vice in Manchester only two weeks before his death. Music and bird lore were combined in his very careful and accurate transcription of bird songs and calls which he used from time to time, illustrating them on the piano, in the ornithological section of the Manchester Institute of Arts and Sciences. They were very highly thought of by those who heard them, though not satisfactory to Mr. Batchelder, because the bird song needs the sliding scale, which the piano does not have. He had studied carefully the birds of the Con- necticut Valley, and later of the Merrimac Valley; indeed he observed them wherever he was, but here again his work was limited by ill health, particularly in the case of the game, water and shore birds. He was a constant contributor to the magazine, Nature Study, pub- lished by the Institute, where his articles, excellent for their matter upon birds and plants, had an added value from the beauty of their style. Whatever came from his pen was charming,— clear, direct and simple, and with the delicious humor coming out suddenly in the most unexpected places. He loved to be with young people, and they, whatever their connec- tion with him might be, were devoted to him — his choir, the young botanists and ornithologists to whom he was always a helpful friend, those engaged in various other branches of Institute work and those who only knew him socially; they all enjoyed his society, and never realized any disparity of years, so youthful was his spirit. His knowledge was freely at the service of all who wanted it, and those far advanced in science often had something to learn of him, but for all this he sought no recognition. He was continually study- ing and learning from pure love of nature, and the glad helpfulness of his disposition made him always ready to impart from his gains; whether he was making a name in the world was far from his thoughts. A loyal son of Harvard, he was the beloved president of the Harvard Club of Manchester, and the dean of the Alumni of the same city. His last musical composition was *A Hymn to Harvard" with Latin words which he wrote for the July meeting of the New Hampshire Harvard Club at Walpole. He did not feel equal to attending, but they had asked him for a poem, and he sent this as his contribution. An attack of grip some ten years ago left him with chronic bronchitis and asthma which, in their turn, induced a peculiar weakness of the heart. These troubles incapacitated him for active work in his pro- 44 Rhodora . [Marcu fession, but he could not give up his music entirely; he played the organ in church, and directed his choir to the last. But work which did not confine him to fixed hours was still in his power, and such occupation he took up with unfailing courage. His indomitable spirit was never impaired by his semi-invalidism, and work of lasting value for the Manchester Institute mentioned elsewhere in this paper, was begun and carried on through the rest of his life, and this courage and persistence in work were lighted up with a gaiety and delightful humor which pervaded and sweetened everything which he said or wrote. The summer of 1911 with its long heated term was very trying to Mr. Batchelder and he weakened under it; he went with his wife and her sister to the Isles of Shoals, a favorite resort of his; he enjoyed his stay there, but the sea level did not agree with him. They went next to another loved locality, Chocorua, amongst the Sandwich mountains, where he had spent eight happy summers. Here too he had great joy, although unable to walk beyond the house grounds. They came home the 15th of September, and for a week he seemed to have regained some strength; after that a slight shock from which he was too weak to rally, proved the beginning of the end. He lived two weeks longer gradually sinking, but with his mind clear to the last, and on the 11th of October he passed away as peacefully as he had lived. : Although Mr. Batchelder had been interested in botany during his college days, it was not until the death of his daughter in 1887 that, as a mental diversion, he took up serious botanical work. He then began the accumulation of a private herbarium to represent his region of the Merrimac Valley. Soon after the formation in 1898 of the Manchester Institute of Science he presented his herbarium to the Institute. In 1902 this collection, together with a large number of additions made to it by Mr. Batchelder, was destroyed by fire, but immediately thereafter he set to work upon a new herbarium. This, at the time of his death, comprised 3,500 sheets. In 1900, in the Proceedings of the Manchester Institute, he published his Preliminary List of Plants growing without Cultivation in the Vicinity of Manchester, . New Hampshire, followed in 1901 and 1902 by Additions to the Prelimi- nary List of Plants, and in 1909 by a complete revision of the Prelimi- nary List; a work which will always be used by students of geographic distribution with the assurance that it was based upon accurate 1912] Nichols,— Notes on Connecticut Mosses,— ITI 45 knowledge of the local flora. Besides this List, which stands as Mr. Batchelder's most important technical publication in botany, frequent notes from his pen were published in Rnopoma, and his name is familiar to New England botanists as the author of the combination Glyceria borealis (Nash) Batchelder. MANHASSET, NEw YORK. NOTES ON CONNECTICUT MOSSES,— III. G. E. NICHOLS. In his last paper on Connecticut mosses ! the writer called attention to the northwestern part of the state, and especially to the town of Salisbury, as a favorable collecting ground. At that time eighteen species of hepatics and mosses were known from no other locality. This number has since been raised to twenty-six. In the present series of notes eleven mosses are recorded from Connecticut for the first time. Of these, nine represent additions due to recent explorations, while the remaining two have previously been reported under other names. | FIssIDENS VIRIDULUS (Swartz) Wahl. Bolton and Danbury (G. E. N.); Hamden (J. A. Allen, 1880); East Haven (Kleeberger). For some time it has been evident to the writer that the Connecticut material which has been passing as F. incurvus Schwaegr. (including F. minutulus Sull.)? comprised a number of distinct forms. Recently all of the available Connecticut specimens, some sixteen packets in all, were submitted to Mr. H. N. Dixon of Northampton, England, for examination, and some of his observations will be of interest to American bryologists. The broad conclusion that he comes to is that there is at any rate none of the true F. incurvus in the lot. More- over, none of the specimens seem to agree with the descriptions of F. minutulus. Mr. Dixon divides the Connecticut specimens into several groups, one of which, as already indicated, he assigns defi- nitely to F. viridulus. A second group, comprising specimens col- lected by the writer in Salisbury and North Branford, he refers to F. viridulus var. Lylei Wils. (= F. exiguus Sull.). The remaining r ! RuHoponRA 13:40. 1911. 2? See Evans and Nichols: Bryophytes of Connecticut 104. 1908. TY" 46 Rhodora _ [Maron groups he hesitates to name definitely at the present time, although he remarks that some of the specimens very likely represent forms of F. viridulus while others approach F. obtusifolius. F. incurvus and F. viridulus are both common and well known British species. The probability that the latter is widely distributed in this country has not, however, been generally appreciated. By many of the European writers of the present day the two are considered con- specific, but both Braithwaite and Dixon consider them distinct. They are indeed uncomfortably close, but in a case like this it is neces- sary to emphasize small dissimilarities. The most striking difference between the two, and one that makes them appear distinct at a glance, is seen in the form and degree of inclination of the capsules. In its typical form F. incurvus possesses a strongly curved and cernuous or horizontal capsule, while in F. viridulus the capsule is usually sym- metric and erect or only slightly inclined. In a recent letter Mr. Dixon remarks that he will not venture to say how far the curving of the capsule is a constant character; there are indications that it may not be; there are certainly intermediate forms. But so far as the character goes the writer, after examining a number of British specimens, agrees with Mr. Dixon that there is nothing among the Connecticut specimens like the typical F. incurvus of Europe. Inci- dentally, the habitats of the two mosses are suggestive. The Euro- pean manuals describe F. incurvus as growing commonly on clay banks and roadsides or in fields. The American plant, on the other hand, is ordinarily associated with moist rocks and only rarely does it occur on earth; in the writer's experience it is to be looked for on boulders in streams or on rocks in shady ravines, but never in open fields. The variety Lylei is a very small plant whose leaves, except on the vaginant lamina, lack the narrow-celled border which is so character- istic in the typical form of the species. GYMNOSTOMUM RUPESTRE Schleich. On limestone in moist shaded ravines, altitude about 800 feet, Salisbury (G. E. N., 1911). Deter- mined by Mrs. E. G. Britton and Dr. A. LeR. Andrews. The Con- necticut specimens are rather short, hardly 1 cm. in height, and pre- sented somewhat the same general field aspect as a Rhabdoweisia. The nearest relative among our local mosses and the only thing with which there is really any danger of confusing it is Hymenostylium curvirostre. The generic distinction between these two seems to be derived from the fact that in Gymnostomum the lid falls off from the 1912] Nichols,— Notes on Connecticut Mosses,—III 47 capsule at maturity, whereas in Hymenostylium the lid remains at- tached to the capsule by the dried-up columella. The leaf characters of the species in question are also different. In G. rupestre the margin is plane or nearly so, and the cells in the apical region are small and poorly defined; in H. curvirostre one or both margins are recurved below, while the cells in the apical region are larger and distinct. The present species ranges more or less extensively through Canada and reaches southward, principally along the mountains, into the northern United States. It has previously been reported from at least two of the New England States, Vermont and Massachusetts, and is common to Europe, Asia, and Africa. The spores ripen in late summer. TORTULA MUCRONIFOLIA Schwaegr. On shaded calcareous shale ledges along the Farmington River, altitude 100 feet, Windsor (col- lected and determined by Miss Lorenz, 1911). This is the only smooth-leaved Tortula that is likely to be found in New England. The species is monoicous so that capsules are usually present, the spores maturing in summer. It should be easy to recognize in the field by the smooth hair-points on the leaves and by the peculiar peri- stome, which conforms to the familiar Barbula type but has a basal membrane nearly half the height of the entire structure. T. mucroni- folia has been recorded from Vermont and Massachusetts; it is widely scattered through Canada and the northern United States, extending southward in the West to Colorado, Nevada, and California, and is common to both Europe and Asia. TorTULA RURALIS (L.) Ehrh. On dry sandy soil over limestone, altitude about 750 feet, Salisbury and Canaan (G. E. N., 1911). During dry weather there is at least a superficial resemblance between this plant and the short, sterile form of Polytrichum piliferum which is common in similar habitats. This is due mainly to the long, hyaline arista which is such a conspicuous feature of the leaves in both mosses. In T. ruralis and in the closely related T. montana this arista is thickly beset with spiny teeth; in the other Connecticut species — T. muralis T. papillosa, T. mucronifolia — it is smooth. T. ruralis and T. montana can be distinguished from one another by the following leaf characters: T. ruralis — leaves squarrose when moist, margin strongly | recurved almost to the apex, upper cells 12-16 u in diameter; T. montana — leaves erect-spreading when moist, margin recurved below but plane in the apical region, upper cells 9-10 u in diameter. T. 48 Rhodora [Marcu ruralis is one of the most cosmopolitan mosses, being known from all of the great continental areas. In temperate North America it is widely distributed, but it is apparently much commoner in the West than in the East. The only other New England stations for it that the writer has found record of are in Vermont and Massachusetts. Fruit, when developed, matures in summer, but the plants are com- monly sterile. RacoMrrRIUM SUDETICUM (Funck) Br. & Sch. Mr. R. S. Williams has referred to this species the specimens recently described by the writer! as R. fasciculare. In general aspect the two species are often similar. But in R. sudeticum some at least of the leaves possess short, denticulate, hyaline hair-points, while the upper leaf-cells are roundish- quadrate in shape. The leaves of R. fasciculare are always obtuse, never developing hyaline points, and throughout the leaf the cells are from three to five times as long as broad. R. sudeticum is quite common in the Salisbury hills and is known from all of the New England States except Rhode Island. Its general distribution is similar to that already given for R. fasciculare. ANOECTANGIUM LAPPONICUM Hedw. On precipitous schistose rocks in a moist ravine, altitude 1600 feet, Salisbury (G. E. N., 1911). Fortunately this moss usually fruits abundantly and the capsules, strongly plicate when dry and empty and barely emergent above the perichaetial bracts, render it easy of recognition. The other Connecticut species, A. Mougeotii, is dioicous and rarely fruits. A. lapponicum is autoicous, the antheridial buds being situated in the axils of the upper leaves and readily demonstrable in most cases. It has been recorded from Maine, New Hampshire, and Vermont, but is evidently much less frequent in New England than the other species. It ranges throughout the northern part of this continent, with a southerly extension in the East as far as the mountains of Alabama, and is found also in Europe and Asia. The capsules mature in late summer. LEUCODON SCIUROIDES (L.) Schwaegr. On the bark of a tree, altitude 150 feet, Ledyard (G. E. N., 1911). As Grout observes,’ this species can usually be recognized in the field by the flagelliform branches which are frequently produced in such abundance as to cause the plant to appear deformed. The leaves differ from those of the 1 RuHopona 13:43. 1911. ? Mosses with Hand Lens and Microscope 389. 1910. ine Uns E 1912] Nichols,— Notes on Connecticut Mosses,— III 49 other two American species, L. julaceus and L. brachypus, in their more narrowly acuminate, longer-celled and nearly entire apices. On this continent L. sciuroides appears to be occasional through eastern Canada, while it has been reported from New York and Penn- sylvania and from all of the New England States but Rhode Island. It is a common European moss and is also known from Asia and Africa. Eropium Braxpowrn (Web. & Mohr) Broth. In a calcareous swamp, altitude 750 feet, Salisbury (A. W. Evans, 1911). The larger size, more ascending habit, and regularly pinnate branching give to this handsome moss a quite different appearance in the field from the common and closely related E. paludosum, the only other American representative of the genus. When dry the plants bear a superficial resemblance to Thuidium abietinum, but the different habitats of the two, together with the softer texture of the present species, preclude any possibility of confusion. Fruit is usually borne in more or less abundance, the spores maturing in May or June. According to Best ! the American distribution is as follows: Greenland; Labrador; Canada and British Columbia; southward to Idaho; Colorado; New York; Vermont. It has now been reported from all of the New England States but Rhode Island. Native to Europe and Asia. DREPANOCLADUS PSEUDOFLUITANS (San.) Warnst. At the margin of Twin Lakes, altitude 750 feet, Salisbury (G. E. N., 1911). De- termined by Warnstorf. This is one of those variable and intergrad- ing forms which group themselves so closely about D. subaduncus (L.) Warnst. (= D. aduncus of most authors). Whether or not it has justifiable claim to specific rank seems open to question. Renauld,? Mónkemeyer,? and Loeske,* after a critical study of numerous speci- mens both in the field and in herbaria, are of the opinion that this and similar forms, such as D. Kneiffii and D. gracilescens, represent merely varieties of D. subaduncus which are due largely to seasonal changes and ecological factors. Dixon, Grout, and Brotherus support this same view. But on the other hand equally careful students, prominent among whom are Limpricht and Warnstorf, regard many of these forms as distinct species. In its typical form D. pseudo- 1 Bull. Torr. Bot.

Gesellsch. zu Leipzig 1-25. 1906. 4 Zur Morphologie und Systematik der Laubmoose 24. 1910. 50 Rhodora [Marcu fluitans is more robust than any of the other species in the subaduncus group, but it bears a marked resemblance to D. Kneiffii and the two are very liable to be confused. In D. pseudofluitans the leaves often reach a length of 5 mm. and throughout the plant are pretty uniformly ovate-lanceolate in shape, tapering gradually toward the apex. In D. Kneiffii the leaves almost never exceed 4 mm. in length and are dimorphic; of the two types of leaves one resembles those of D. pseudofluitans in shape, but the other is broadly ovate and tapers rather abruptly. Both kinds of leaves are usually present in the same individual. Furthermore, in D. pseudofluitans the leaves near the tip of the shoot have a tendency, which is usually not evident in D. Kneiffü, to wrap themselves more or less loosely around the stem. The length of stem is also said to differ, but specimens of each species have been collected by the writer in which the stem measured fully a foot in length. On the whole, however, the distinctions which can be brought out in a description are rather unsatisfactory for, as Loeske remarks,! the two forms are more readily separated by their general habit than through any anatomical differences. D. pseudofluitans sometimes grows in ditches or in shallow depressions which are dry during the summer, but in such habitats it is poorly developed. It thrives most luxuriantly in places where it is almost completely sub- merged throughout the year. In a locality of this sort along the lake- ward margin of a swamp which borders one of the Twin Lakes there are pure mats of D. pseudofluitans many square yards in extent. The range of this species has not been definitely established, but for the present it may be assumed that its distribution coincides approxi- mately with that of D. subaduncus. So far as the writer is aware no other New England stations have been published. In passing it is worthy of note that this moss, together with D. Sendtneri var. Wilsoni ?, which occurs in the same locality, may be of considerable importance locally in connection with the production of marl. Davis has shown? that the extensive marl accumulations, which are a well known feature of lakes in limestone regions, are largely the result of plant activity, and he has cited a number of algae and seed plants which play an important róle in this connection. In ! Moosflora des Harzes 308. 1903. ? D. Wilsoni Schimp. is often treated as a separate species, but by Warnstorf it is regarded merely as a variety of D. Sendtneri. 3 Geol. Surv. Mich. 83: 65-100. 1903. 1912] Nichols,— Notes on Connecticut Mosses,— III 51 the present case the leaves and stems of the two mosses referred to above were covered with a thin, loose crust of calcium carbonate which they had apparently precipitated from the water, and which gave them an unnatural grayish-white appearance. DREPANOCLADUS VERNICOSUS (Lindb.) Warnst. In a boggy swamp at the margin of Twin Lakes, altitude 750 feet, Salisbury (G. E. N., 1911). Determined by Warnstorf. With the exception of D. scorpi- oides this is the only one of the Drepanocladi in which the stem lacks a central strand. It also differs from all the other Drepanocladi thus far recorded from Connecticut in the total absence of specially differentiated alar cells. On the whole D. vernicosum is a northern moss and has been rather infrequently collected in the United States, the only stations in the East that have come to the writer's attention being in Ohio, western New York, eastern Pennsylvania, northern New Jersey, and northwestern Vermont. It is found in both Europe and Asia. According to the majority of the European authorities this moss is confined to swamps and bogs that are free from lime; so that on first thought it would hardly be looked for in the Twin Lakes swamp which overlies marl deposits of considerable depth. So far as the writer has observed, however, it does not ‘occur around the lakeward border of the swamp but grows at a distance from the open water, in places where a considerable thickness of peat has been laid down. And this seemingly restricted distribution suggests a possible explanation for the anomaly. As has been pointed out by Transeau ! humic acid, which is particularly abundant in peaty soils, forms insoluble com- pounds with alkaline earths. So that where there is an appreciable depth of peat the vegetation growing at the surface may be affected little or not at all by the calcareous nature of the substratum, owing to the fact that whatever lime may be dissolved in the water will be precipitated through the action of the humic acid before it has pene- trated far into the peat. CLIMACIUM DENDROIDES (L.) Web. & Mohr. On moist banks in a ravine, altitude 1600 feet, Salisbury (G. E. N., 1911). Determina- tion verified by Dr. Grout. The seeming rarity of this moss in most parts of the East may in all probability be accounted for by the fact that it is usually mistaken for the better known species, C. america- num, which it closely resembles in habit and general appearance. ! Bot. Gaz. 40: 375. 1905. 52 Rhodora [Marcu But the branch leaves and capsules in the two plants are quite distinct. In C. americanum the leaf bases have broad, crispate auricles, and a large proportion of the leaves are acute. In C. dendroides the leaves may be slightly auriculate but the auricles are usually flat, while the majority of the leaves are very obtuse. The areolation also differs, the median cells in the former being from five to seven, in the latter from seven to ten times as long as broad. The capsules of C. den- droides ripen in late autumn and are much smaller than those of C. americanum. It probably occurs throughout northern North America and has been accredited to Maine, New Hampshire, and Vermont. Also common to Europe and Asia. In addition to the mosses listed above there are a number of new stations for species which have heretofore been known from but one or two localities. These are as follows: Fissidens bryoides forma inconstans Schimp., Farmington (Miss Lorenz); Encalypta ciliata, Salisbury (A. W. Evans); Schwetschkeopsis denticulata, Colebrook (G. E. N.); Myurella julacea, Salisbury (Miss Lorenz); Thuidium abietinum, Canaan (G. E. N.); Brachythecium acuminatum and Amblystegium vacillans, Salisbury (G. E. N.). Anacamptodon splach- noides may also be recorded from two more towns, Colebrook and North Branford (G. E. N.). At the present writing 309 species of mosses are known to occur within the limits of the state. Three spe- cies have been dropped from the list and thirty have been added dur- ing the last four years. During the same time the number of hepatics has been increased from 107 to 128, thus making a total at this time of 437 bryophytes in Connecticut. In conclusion attention is called to a number of errors which have been noted in the Bryophytes of Connecticut. P. 101, Dicranum fulvum Hook. should read D. montanum Hedw.; synonym should be omitted !: p. 109, in the key to species of Tortula the characters should be interchanged to read as follows: T. montana — midrib excurrent into a long toothed hair-point; T. muralis — midrib ex- current into a long smooth hair-point. P. 111, in the key to species of Grimmia the characters of the leaf-cells in G. conferta and G. apo- carpa have been exactly transposed. Also, the Stafford station for Polytrichum alpinum, reported in the last series of Notes?, must be omitted; the mistake was due to a confusion of labels. YALE UNIVERSITY. 1 Already noted by Howe: TUTON $: 37.. 1909. 2 Ruopora 18:46. 1911. 1912] Sherman,— Morels in October in Massachusetts 53 MORELS IN OCTOBER IN MASSACHUSETTS. JuLIA WINGATE SHERMAN. Prizinc mushrooms for their esculent qualities and having the mushroom hunger upon me, I went out the first of October to gather some Tricholoma personatum. After having filled a large paper bag with that species and about a quart of Marasmius oreades — which has been conspicuously abundant the past season — I started for home well satisfied with my luck, looking forward to the enjoyment of these delicacies. As I was passing some recently turned soil where a granolithic sidewalk had been made, my attention was arrested by some morels growing at my feet. I picked about a dozen of varying size and shape. When I reached home I attempted to look them up. I could find no records of morels being found in the autumn, nor could I find any description of a species which agreed perfectly with the specimens found. I put the morels in a white enamel plate to dry near the gas range. They gave off spores freely. These were of a rich pinkish yellow, apricot, I think it would be called. At short intervals during the month I visited the locality where the morels grew. I found in all about seventy-five. 'The last were picked October 28th. Although I looked for them several times later none were found. While I was inclined to think they were a form of Morchella conica, I could not completely identify them with that species owing to their manner of growth and to other peculiarities, for only the smaller ones were conical As they increased in size the growth became lateral in cap and stem. About fifty per cent had an opening in the apex about a quarter of an inch in diameter. They varied in size from the smaller conical ones, about the size of a lady's little finger, to the large broad ones, about twice the size of a hen's egg. The color of the pits, in fresh specimens, was smoky and dark; in some nearly elephant gray. The edges of the ridges between the pits were white or creamy, forming a beautiful contrast of color. The stem was larger at the base than at the top, which was wrinkled and brownish and rather squamulose or scurfy. Inside the morel was creamy white. Ur pm 54 Rhodora [Marcu The location of these morels was peculiar. Many were growing on or near rocks.’ Only the small amount of clayey subsoil, which had adhered to the rocks, on their being thrown aside, made their growth possible. One large specimen was growing from the side of a square paving stone of granite. This clayey subsoil had been thrown under an elm tree by workmen who had recently completed the side- walk mentioned. All the morels were found in a space of about fifteen square feet. Specimens which I sent to Dr. Charles H. Peck of Albany, New York, for examination proved to be the first living morels he had ever seen in October. He found the spores from dried specimens to agree well with those of M. conica, although a few ran up to 32 X 20 u in size. The specimens ran smaller than typical M. conica and the scurf on the stem was darker colored. "The color of the hymenium and the whitening of the edges of the ridges, the lateral growth and the tendency of all the larger ones to depart from the conical form, and the opening of the apex have led Dr. Peck to consider this plant a distinct variety, of which a description may be looked for in his next report. Hereafter, then, it will do no harm to look for morels in the fall. Dr. Peck writes: “I have not before known of a morel appearing in autumn, and it may be an interesting question whether this should be considered a belated early summer form, or an extraordinary pre- cocious spring form or an autumnal form pure and simple. If it never appears except in autumn I think it should be deemed worthy of specific distinction instead of varietal. Further observations must settle this.” ROSLINDALE, MASSACHUSETTS.

Ware botanizing on Mount Killington in September, 1910, in company with Harold G. Rugg of Hanover, N. H., and D. Lewis Dutton of Brandon, Vt., I found growing in an open spot by the road- 1912] Fernald,— Two Rare Junci of eastern Massachusetts — 55 side leading to the old hotel at about 3700 feet elevation a goldenrod which attracted my attention from some distance because, unlike the other large-headed species which was growing ia abundance all about (S. macrophylla), its inflorescence consisted of close spike-like racemes and it grew in a clump of considerable size. It was so late in the season that the material obtained was poor and the plant could not be determined satisfactorily but when some better specimens from the same station were sent to Prof. M. L. Fernald in 1911 he pronounced the plant to be Solidago. calcicola Fernald. This is a new goldenrod for Vermont and a considerable extension of the range of this plant, which has heretofore been found within the limits of the United States only in northern Maine, having been collected elsewhere only in Gaspé county, P. Q. The Vermont material was taken a quarter of a mile below the rocky cone of Killington peak. In gathering data for a revision of the Vermont Flora published in 1900 by Brainerd, Jones and Eggleston the writer has received the past season the following records of plants collected that are new to this state: Bromus altissimus Pursh and B. incanus (Shear) Hitchc., in Pownal, R.

RUTLAND, VERMONT. Two RARE JUNCI OF EASTERN MaSSACHUSETTS.— In May, 1910, when the Committee on Local Flora published their records for the Juncaceae (Ruopora, xii. 95-99), only one station each was known in eastern Massachusetts for Juncus brachycarpus and J. effusus, var. decipiens — the former at Scituate, the latter at Ipswich. Since these plants are so extremely local, not only in Massachusetts but in all New England, it is worth recording that in the Charles W. Swan 56 Rhodora [MARCH herbarium at Yale University there is a specimen of J. brachycarpus collected by Dr. Swan in “ West Boston,” May 15, 1884, and a sheet of J. effusus, var. decipiens collected by Dr. Swan at East Gloucester.— M. L. FERNALD, Gray Herbarium. LINUM CATHARTICUM IN MaiNE.— As I was lately revising my specimens of the genus Linum in my herbarium, I was surprised and pleased to come across a sheet of four fruiting specimens of the European Fairy Flax, Linum catharticum L., from “The Basin,” Vinalhaven, Maine, collected by Mr. William W. Dodge, September 1, 1894. This is the first record for New England, but the Fairy Flax has been found at three stations in British America. Prof. John Macoun has reported it (Cat. Can. Pl., i. 501, 1886) “on waste ground along the seashore at Pictou, N. S.” and Prof. M. L. Fernald has discussed and recorded it (RHopoRA, v. 119, 1903) from Sydney, Cape Breton, and also (Ruopora, xiii. 116, 1911) as growing along the railway at Birchy Cove on the western coast of Newfoundland. Vinalhaven is an island at the mouth of Penobscot Bay and is 300 miles in a straight line from Pictou, the nearest recorded station for the species. Doubtless the plant occurs at other stations along the coast.— WALTER DEANE, Cambridge, Massachusetts. : ASTRAGALUS CONTORTUPLICATUS ON WooL-wasTE.— In June, 1911, on the J. V. Fletcher farm in Westford, Massachusetts, where wool- waste is used as a fertlizier, I found growing with Thlaspi arvense, Sisymbrium Sophia, and Dracocephalum thymiflorum (see Rnopona, xii. 212) one plant of a Milk Vetch, which with the help of the Gray Herbarium has been named as: “ Astragalus contortuplicatus, a native of eastern Europe, Siberia and Northern India. No American record is found of this species."— Emity F. FLETCHER, Westford, Massachu- setts. Vol. 14, no. 158, including pages 25 to 40, was issued 1 February, 1912. TRbooora JOURNAL OF THE NEW ENGLAND BOTANICAL CLUB Vol. 14. April, 1912. No. 160 THE BOTANICAL AND OTHER PAPERS OF THE WILKES EXPLORING EXPEDITION. FRANK S. COLLINS. THE United States Exploring Expedition under the command of Charles Wilkes, U. S. N., started in 1838 and continued until 1842; the scientific results of the expedition were published in a series of volumes, the first in 1846, the last in 1874. In 1862 separates of the text and plates referring to the lower cryptogams are said to have been issued, with some plates representing phaenogams; the text for the former beginning with page 113; the text belonging to the latter, beginning with page 205, did not appear until 1874, when all were issued together as Vol. XVII, the title page bearing the double date 1862, 1874. In looking up the original descriptions of some species of algae published here, I found that the references to them by later authors were frequently erroneous, and I thought a note giving the correct references might be of use. While getting together the data. for this I came upon some rather interesting facts in regard to other papers issued in the series, and my note has been gradually extended beyond the original plan. I will first give the results of my investi- gation as far as the algae are concerned, afterward and more concisely what I have found of interest as regards the rest of the series. The work seems to be little known to writers on algae; it is not included in any of the bibliographies of De Toni, Sylloge Algarum, with the exception of a reference in Vol. I, p. IX, to the Diatomaceae, which occupy only 9 pages of the work; the reference is to Vol. VIII of the series, which is incorrect. In the very full synonymy and 58 Rhodora [APRIL lists of species inquirendae given by Bornet & Flahault! no reference is made to Nostoc expansum, described and figured in the Wilkes paper, p. 164, Pl. VI, figs. 1 & 2 Mme Weber-van Bosse,’ however, cites the work, as do the Gepps,* but as will be seen later, the citations in both these cases must be revised. Page 153 is the subtitle for the algae, and reads "Algae. By Jacob Whitman Bailey and William Henry Harvey,” but whenever in the following pages the two names are given as Joint authors of a species, the order, except among the diatoms, is reversed, being Harvey and Bailey,* which as will be seen later, is the correct form. There is seldom anything to show whether a name appears here for the first time, either as a new species or as a new combination. A Latin diagnosis is sometimes given for a species attributed to some other author, without any citation; for instance Gymnogongrus vermicularis J. Ag.; on p. 164. Few synonyms are given, and in some instances they are printed exactly as independent species; for instance Fucus vermicularis Turn., on p. 164. Errors in spelling occur, like Ectocarpus namulosus for E. hamulosus on Plate VII. All these things tend to confuse the writer who wishes to cite from this work, but they are only the beginning of his troubles. One genus and four species, which have the appearance of being here published, had al- ready been mentioned, with sufficient description, by Harvey; the genus Chlorodesmis in 1858, Dasya plumosa* Rhodymenia Wilkesii, Gigartina mollis,’ G. exasperata? No reference is made in the Wilkes paper to any of these earlier publications, with the exception of Rhodymenia Wilkesii, where we have in the text, p. 162, “A very 1 Bornet & Flahault, Revision des Nostocacées Heterocystées, Ann.

Gepp, The Codiaceae of the Siboga Expedition; Siboga-Expeditie, Monogr. LXII, Leiden, 1911. 4The order ‘‘Bailey and Harvey” on the title, while the following species are "Harvey and Bailey," seems mere carelessness, but a possible explanation was sug- gested to me by an advertisement of a Philadelphia publishing house of a second edi- tion of the narrative, Vols. I-V of the government issue. *'' Everything about this work wil be STRICTLY AMERICAN...." It may have occurred to some one that it would not be STRICTLY AMERICAN to put the name of Prof. Harvey of Dublin before that of Prof. Bailey of West Point. 5 W. H. Harvey, Nereis Boreali-Americana, part 3, p. 29. * W. H. Harvey, l. c., part 2, p. 66, 1853. 7 W. H. Harvey, l. c., part 2, p. 147. 8 W. H. Harvey, l. c., part 2, p. 175. sW. H.

Ag., Sp. Alg. 2, p. 376. W. H. H.” Chlorodesmis is characterized as “Nov. Gen.," p. 172, but on p. 173 we find “[A second reputed species of this genus is described and figured in Harvey, Ner. Bor. Amer. 3, p. 30-40, but that may possibly be a Derbesia. W. H. H.J” That these things should be published as new in 1862, with refer- ences to earlier descriptions in 1853 and 1858, is not the worst; the one genus and four species mentioned above, with another genus Notheia, and twelve other species in the Wilkes paper of 1862, were all properly published by Harvey and Bailey in 1851!! The species in question are, in addition to those already mentioned, Notheia anomala, Nostoc expansum, Ectocarpus hamulosus, Chondrus uncialis, Gracilaria filiformis, Gymnogongrus ? dendroides, Gelidium unilaterale, Liagora hirta, Caulerpa falcifolia, C. Pickeringii, Dictyota bidentata and Chlorodesmis comosa. The seventeenth species of the 1851 list is Hypriea (probably a misprint for Hypnea) Coulteri, which does not appear in the 1862 work. There is no mention whatever of this earlier paper in the later work, while in the Nereis, under Rhodymenia pertusa we find the synonym “Rhodymenia Wilkesii Bail. & Harv. in Bot. Expl. Exped. cum Icone, ined.," and under Chlorodesmis the remark “ The genus Chlorodesmis was founded by the late lamented Professor Bailey and myself on an alga brought by Captain Wilkes from the Feejee Islands.” It is not difficult to understand why the Harvey and Bailey paper of 1851 has been forgotten. It is possible that a careful search would find authors who mention it, but the only instances in algological papers that have come to my notice are Setchell & Gardner,? and Tilden? But the unfortunate fate that has pursued the Wilkes algae from the start seems to have extended to both of these references; Setchell & Gardner include both the 1851 and the 1862 papers in their !

This is probably a misprint, but, as will be seen later, some of the memoirs of this series may be found in different copies with different title pages, and there may have been an error in the volume number in this case. Unfortunately, the question cannot now be settled, as the copy used was destroyed in the San Francisco fire. Miss Tilden makes no reference to the 1862 paper, and omits Bailey as joint author of the 1851 paper, placing it under W. H. Harvey only; and the date is vaguely given as 1848-1851. With our present recognition of the necessity of accuracy in matters of publication and citation, such baffling and misleading work would be little short of criminal. Even after making allowance for the looser treatment prevailing fifty years ago, it is difficult to understand it. The two genera in question have been subjects of considerable study and discussion, and the fact that a date of publication later than the true one has been assigned to them might have had serious results in nomenclature. De Toni’s Sylloge is the index to which one naturally first refers when looking up matters of this kind. In Vol. I, p. 439, 1889, we find “ Chlorodesmis Bail. et Harv. [1858] in Harv. Ner. bor. Am. III, p. 29." In Vol. III, p. 224, 1895, “ Notheia Bail. et Harv. [1855] in Hook. Fl. of New Zeal. II, p. 215 et Botany of Wilke's Expedition (ined.)" These should now read Harvey & Bailey [1851] in Proc. Boston Soc. Nat. Hist., Vol. III, p. 371 & p. 373. It may be of interest to note that specimens of many of the species, some of them evidently the individuals from which the plates were drawn, are in the herbarium of Brown University, Providence, Rhode Island, where Professor W. W. Bailey, son of J. W. Bailey, was for many years at the head of the department of botany. When we look up the history of the whole work, the element of uncertainty and inconsistency that we found as to the paper on algae is still noticeable. "The Act of Congress authorizing the work, under date of Aug. 26, 1846, provides for a series of volumes similar to those of the Voyage of the Astrolabe, to be issued in 100 copies, and dis- tributed as follows: — one copy each to Captains Wilkes, Hudson and Ringgold, one to the Library of Congress, one to the Naval Lyceum at Brooklyn, one to each State of the Union, one to each friendly foreign power, and one additional copy each to France and Great Britain. The number of states increased during the period 1912] Collins,— Papers of Wilkes Exploring Expedition 61 from 1846 to 1874; whether the number of friendly foreign powers increased or decreased during this time, I have no idea; in any case the number available for general distribution must have been ex- ceedingly small. In a communication from the Librarian of Congress, whose kindness in furnishing me important data in regard to the matter I gratefully acknowledge, is a statement which incidentally shows what might have been thus available, and at the same time shows that probably none were really available. A fire at Washing- ton, April 11, 1856, destroyed about 21 copies of 18 of the volumes then in print, and of those destroyed only the narrative volumes and Vols. VI-VIII of the memoirs were replaced by a new impression. Probably none of the copies authorized by Congress ever reached the general public. The General Catalogue of Government Publications by B. P. Poore, issued in 1885, at page 500 has a list of the volumes, but the fatality that seems to attach to the whole business extends to this also, and it is incorrect in at least one particular, so that I shall give instead the list made out for me by the Chief Bibliographer of the Library of Congress, adding the author's names, which were given in only a few instances in the list. Vols. I to V, with an atlas, contain the narrative of the expedition, were issued in 1844, and need not be here considered. They seem, however, to have attracted interest, and several editions, some in smaller and less expensive form, were issued soon after by publishing houses. VI. Philology, Horatio Hale, 1846. VII.

Hydrography, Charles Wilkes, 1861, with two Atlas volumes, both 1858. XXIV. Physics, never published. This is the list of what we may call the official set, the 100 copies authorized by Congress; the volumes are sumptuously bound in full morocco, with elaborate ornaments stamped in gilt, eagles, sunbursts etc. The Massachusetts set can be seen in the State Library in the State House in Boston; it has all the volumes issued with the excep- tion of Vols. XVII & XIX. The printed catalogs of the State Li- braries of Ohio and California show very nearly the same, and the Rhode Island set, deposited with the Rhode Island Historical Society, is similar. I have not looked up other state sets, but it may fairly be assumed that they are nearly the same. Soon after the work was authorized by Congress, protests came in from scientific and other societies against the limitation of the edition, providing no copies whatever for institutions or the public.! These were referred to the Joint Committee on the Library of Congress, which reported? recommending 400 additional copies, 285 to be distributed to institutions in the country, the remainder to be sold to the public. Congress ‘ordered 5000 copies of this report to be printed, and then paid no further attention to it. Somewhat grudg- ingly, authors were permitted to have additional copies printed at their own expense, and this was taken advantage of to a varying extent by different authors; copies so issued are what one finds in various public and scientific libraries. When not rebound, they are in the ordinary black cloth of government publications of the period. Of Vol. VI there appear to have been printed 150 such copies, the responsibility being taken by the firm of Lea & Blanchard of Phila- delphia. I do not think that over 100 copies were printed in this way of any other volume, and of some the number was less; in one or two 1 See Cong. Doc., Vol. 476, No. 327; Vol. 533, No. 57 etc. ? Cong. Doc., Vol. 477, No. 405. 1912] Collins,—Papers of Wilkes Exploring Expedition 63 instances I cannot find that any extra copies were printed at all. The volumes of the official edition had no publisher's name on the title page, but only “Printed by C. Sherman, Philadelphia " or a similar form. Some of the copies of the publie edition are the same, but others have various imprints. In most but not in all cases, the reverse of the title has “ Printed by C. Sherman” or some form similar. These volumes were generally placed by the authors in the hands of some publisher, whose name appears on the title; sometimes the work was transferred from one publisher to another, and another title used. Being sold individually, volume numbers were often omitted, which was not unnatural, but it is not so easy to understand why in some cases a different volume number from that of the official edition should be used. I have drawn up a list of these variations from the official set, in the copies I have examined in the libraries of Boston and Cambridge; it is probable that copies in other places will show additional varia- tions. For the convenience of any one who may wish to inspect any particular form, I use initials to indicate the library, as follows:— BPL, Boston Public Library. NH, Boston Society of Natural History.

Lippincott & Co.; NH, BA, BPL. Of Vol. XXII and its two atlas volumes I have seen only the official copy. The government catalog gives Vol. VIII by Cassin, but there was 1912] Collins,— Papers of Wilkes Exploring Expedition 65 an earlier Vol. VIII by Titian R. Peale. The official set bas this as Vol. VIII, part 1, the Cassin volume being part 2. Peale was with the expedition in charge of the department of Birds and Mammals, and on his return prepared the plates and wrote the volumes of text. This was printed and distributed to the states and presumably to the foreign powers. Wilkes, who had taken on the superintendence of the publications, was dissatisfied with Peale’s work, and arranged with Cassin to prepare a new volume in place of it. The copies which had been distributed were not recalled, but all remaining copies appear to have been destroyed, including the copy of the Library of Congress, which lacks this volume. I cannot find that any author's copies were printed, and it must be considered one of the rarest of scientific works. Some good ornithologists, to whom I wrote inquiring about it, had never heard of it. Two ornithologists, both of high authority, knew it; one writes me that the 100 or more new species described in it were properly reduced by Cassin to about 30; the other writes me that Cassin severely condemned Peale’s descriptions, but modern ornithol- ogists consider Cassin’s descriptions little better. The rarest of the botanical works is probably the Atlas to Vol. XVII, Ferns etc. by Brackenridge, but the reason for this rarity I do not know. Vol. XV, Phanerogamia, is sometimes found without the Atlas, and vice versa. Sabin,! states that by some mistake a large part of the edition of the plates was sold at auction, unbound, without the text. I can find no details as to this, but one copy of the Atlas in the Boston Public Library was presented by Leonard & Co., January 5, 1858. Leonard & Co. were leading book auctioneers in Boston for many years, and may have made the sale referred to. To explain the non-publication of Vols. XVIII, XXI, XXII and XXIV would take much space and would bring up interesting but not specially edifying stories of inefficiency, extravagance and plunder, which when compared with present conditions, indicate that the standards jn such matters are higher now than in the days of the fathers. At the time the publication was authorized there was no National Museum, no Smithsonian Institution, practically no organ that could deal with scientific matters; Congress, probably with a vague feeling that literature had something to do with science, and 1 Books relating to America, Vol. VII, p. 395. 2 Details of dissensions following the expedition, and reports on manner of pub- lishing will be found in Cong. Doc., Vol. 494, No. 47, Vol. 495, No. 217, Vol. 994, No. 391 and Vol. 1667, No. 60. 66 Rhodora [APRIL that a library had something to do with literature, put the matter in charge of the Joint Committee on the Library of Congress, with which it remained from 1852 to 1874, the date of the last issue. The com- mittee, its membership continually changing, left the whole matter practically in the charge of Wilkes, who dealt with authors and printers much as he was accustomed to do with sailors and marines. The qualities that made him an excellent commander of an exploring expedition, accomplishing a work of lasting credit to the navy and the nation! were not suited to estimating the value of scientific memoirs. We have already seen how Peale’s memoir was treated by him. . William Rich, the botanist of the expedition,” prepared a volume on botany, which was never printed; Louis Agassiz two volumes on ichthyology, Gray a second volume on botany; the manuscripts of these are probably somewhere in Washington; but of course the long time since they were written would make their publication out of the question now. The Library of Congress claims to have a volume, without title, of the plates prepared for Agassiz’s memoir. If printed at all, no doubt the 100 copies were printed, but the Museum of Comparative Zoology, Agassiz’s own Museum, knows nothing of them.? There is no evidence of anything dishonest on the part of Wilkes himself but the report of the Library Committee in 18764 shows that the greater part of the money appropriated, about $350,000.00 in all, had gone for “superintendents,” the amounts for the work itself being in some years absurdly small. The disgust of Congress at these 1 Dana, who had plenty of reasons to be dissatisfled with him as regards the publi- cation, calls him ‘‘An excellent officer"; * Perhaps no better could have been found in the navy at that time." For a very good account of the voyage from a scientist's point of view, as well as of the curiously annoying restrictions Wilkes attempted to impose on the authors of the memoirs, see The Life of James Dwight Dana, Scientific Explorer, Mineralogists, Geologist, Zoologist, Professor in Yale University, by Daniel C. Gilman, President of Johns Hopkins University. New York & London, Harper & Bros., 1899. An indication of the change of conditions in the past 60 years is shown by Dana's comment on the one particular restriction that seems to have made him lose his temper, the ruling that the work should be done at Washington. * The absurdity of writing a scientific memoir in a city without books!” ?'The botanist of the expedition was to have been Dr. Gray, who was regularly appointed and drew advance pay. For some reason he decided not to go. Interest- ing letters in regard to this are included in the volume of letters by Jane Loring Gray, Boston, 1893. 3 The payments to the authors were liberal; according to the report of the Library Committee, Cong. Doc., Vol. 994, No. 391, such payments on the rejected or neglected volumes were Rich, $4,560.00; Gray, $3,000.00; Agassiz, $5,916.66. 4 Cong. Doc., Vol. 1667, No. 60. 1912] Collins,— Papers on Wilkes Exploring Expedition 67 revelations led to an immediate stoppage of the work, without regard to the memoirs ready and waiting. The money sufficient to publish them bad been appropriated over and over again but had been squan- dered. My interest in the matter began with some references to Vol. XVII, and this volume deserves still further notice. Its fate was in some ways the most peculiar of all. This volume was intended to include the cellular cryptogams, as well as the phanerogams of the Pacific coast of the United States, the latter part having been assigned to Dr. John Torrey. His report was ready in 1861, but had not been published at the time of his death. Dr. Asa Gray added some notes, and in a short preface dated Washington, April 15, 1873, explained his relation to Dr. Torrey’s work, and to some extent the circumstances of the twelve years delay since it was written. The lichens by Tucker- man, pp. 113-152, Algae by Bailey & Harvey, pp. 153-191, Fungi by M. A. Curtis & M. J. Berkeley, pp. 193-203, and the Torrey-Gray section, pp. 305-514, were issued in 1874, the title page bearing the double date 1862-1874. A note states that pp. 113-203 with the plates belonging to them and also the 17 plates of the Torrey-Gray section, were printed in 1862, and a small number of copies distributed. I have never seen one of these copies, nor has any of my botanical friends, and I have not found them mentioned in any catalog. Pp. 1- 112 were assigned to the Musci, by W. S. Sullivant, but he apparently became tired of waiting for their publication by the government, and in 1859 issued an imperial folio atlas of 26 plates with 32 pages of text, corresponding to the missing pp. 1-112 of Vol. XVII. "There is a copy of this at the Gray Herbarium. All the copies I have seen of Vol. XVII appear to be of the public or author's edition, the Gray Herbarium had the supply of these and of the Sullivant folio, but I believe they are now all sold. Some copies have the plates in a separate atlas volume, the same as the plates of the other memoirs in the series; more commonly the plates are folded, mounted on guards and bound with the text. No complete copy of the volume, with pp. 1-514, has been seen by me, but Dr. H. H. Bartlett was so kind as to look up at my request the copy in the Library of Congress; he reports it as complete, with a title page dated 1874, giving full statement of the contents; it has the full morocco binding of the official set. It is evident then that the whole volume was officially printed, but it was never distributed to the states, nor presumably 68 | Rhodora [APRIL to the foreign powers. It is to be hoped that some one with influence enough to overcome the official inertia will have the missing ninety and nine brought forth from their hiding, and sent to their destina- tions. As to Vol. XIX, the other one missing in the Massachusetts set, all the copies I have seen are of the public issue, and bear different publishers names, though all printed by C. Sherman. It is not likely that Sherman printed copies for the author but not for the government; probably the 100 copies of this volume might be unearthed in Washing- ton by one who had time and energy for the work.! The insufficient supply of these memoirs has been reduced below the original amount by fires, the loss in this way having been unusually heavy. I have already referred to the fire at Washington. There were losses in two fires at Philadelphia near that time, so that the official edition of most of the memoirs was reduced to about 70. Dana’s volume on zoophytes was an exceptional sufferer; the original colored drawings were lost in one of the Philadelphia fires; most of the type specimens in the Chicago fire; and at two times, a fire at New Haven destroyed some of his own extra copies, the second fire taking all that was left. In ascertaining whether any other states had sets like that of Massachusetts, I have written to the State Librarians of Rhode Island, New York and Minnesota; of these the last two report that they had sets, but that they had been destroyed in conflagrations. It is not likely that the proportion is the same among the other states; but one cannot tell what a thorough round-up might show. MALDEN, MASSACHUSETTS. 1 In this connection see Cong. Doc.

On referring to the discussion of Salix balsamifera Barratt in Sar- gent’s Silva, the writer recently noticed a statement which, by frequent repetition, has come to be strongly associated with the history of our knowledge of this unique species. The statement referred to:— “Salix balsamifera was first collected by Mr. Henry Little in August, 1823, on the bank of the Ammonoosuc River among the White Moun- tains of New Hampshire" !— originated with the late M. S. Bebb in 1879. At that time Bebb called attention? to Mr. Little's speci- men preserved in the herbarium of the Academy of Natural Sciences of Philadelphia; but, although the type material of the species which is botanically of the greatest importance was gollected by Sir John Richardson from "Lake Winnipeg and the Saskatchawan," ? Mr. Little's earlier and long-overlooked collection of S. balsamifera has received such unusual prominence in the past third of a century as "the oldest herbarium specimen extant” £ of the species that it is appropriate, for the sake of historical accuracy, to record a still earlier collection of this willow. And, just as the Little specimen of S. balsamifera lay in a public herbarium unrecognized and unrecorded for more than half a century, it is perhaps noteworthy that the earlier- discovered but heretofore unrecorded specimen was collected 120 years ago and until 1903 lay apparently unnoticed (at least unde- termined) in the herbarium of the Muséum d’Histoire Naturelle at Paris. In 1903 while examining the plants in the Michaux Herbarium the writer was interested to find this sheet of very characteristic foliage of Salix balsamifera bearing in Michaux’s hand the label: “dans les marais de Batiscan.” The species, presumably because represented 1 Sargent, Silva, xiv. 64 (1902). 2 Bebb, Bot. Gaz. iv. 190 (1879). * Hook. Fl. Bor.-Am. ii. 149 (1839). +" Here we have, I doubt not, the oldest herbarium specimen extant of S. balsami- fera"— Bebb, Bull. Torr. Bot. Cl. xv. 122 (1888). “It was first discovered more than half a century ago among the White Mountains of New Hampshire''— J., Garden and Forest, i. 246 (1888). ‘‘ This fragmentary specimen he [Bebb] recognized as Salix balsamifera and realized that it was the earliest collection of the species.’’— Sargent, Garden and Forest, vi. 28 (1893). 70 Rhodora [APRIL only by foliage, was not described in Michaux’s Flora Boreali- Ameri- cana, and in the herbarium the sheet had been left among the unnamed specimens following those which formed the basis for the F lora. The label, “in the bogs of Batiscan," gives the desired clue to the date of collection, for on the 14th of July, 1792, Michaux botanized in the bogs at Batiscan (in Champlain Co., Quebec) and there collected some very characteristic bog plants. His journal of that date reads: “Le 14 herborisé a 8 li. de distance des Trois Riv. dit Batiscan; plus bas Andromeda polifolia, Kalmia glauca, angustifolia; Azalea glauca [?, Ledum palustre [groenlandicum], Comarum...."'! Whether or not Michaux's material of Salix balsamifera gathered in 1792 is the earliest collection of the species, which is not improbable (although this willow is common in eastern Newfoundland and various regions of eastern Canada whence early collections of plants were carried to Europe), it is obvious that his material was collected thirty-one years earlier than Little's specimen from the White Mountains, the speci- men which has so often been cited as the earliest collection of the species. Gray HERBARIUM. Bowman’s Forest Puystocraruy.? — Although written primarily for foresters and students of forestry, Professor Bowman's book will find an interested circle of readers among students of plant-geography, for in it are stated in clear and readable style the general physiographic features of the United States, with discussions of soils and climatic conditions, and much other matter which bears directly upon the distribution, not only of forests, but of other plants as well. The field-botanists whose interests lead them to the boundaries of physiography and geology are constantly in need of authoritative information upon these allied subjects and by them Bowman's Forest Physiography will be heartily welcomed.— M.

John Wiley & Sons. 1912] Field Excursions of New England Botanical Club 71 FIELD EXCURSIONS OF THE NEW ENGLAND BOTANICAL CLUB.} As a result of the first field day of the New England Botanical Club, centering about Providence, Rhode Island, on May 30, 1911, the collections of the Club gained more than 800 specimens and several species not previously known from Rhode Island. This pioneer experiment of the members of the Club in making a concerted effort to develop the Club Herbarium was considered a great success, and the experience of last year justifies the continuance of such field days. The importance of such outings cannot be over-estimated, for not only does the Club Herberium gain materially but the members have an unusual opportunity for congenial field-trips and exchange of experiences. And now that the Club is so soon to have commodious quarters with fireproof cases and other up-to-date facilities for the development of its Herbarium, the ideal toward which we have been modestly working can be more readily accomplished. As already known to some members of the Club, the aim of our Curators has been to make our Herbarium thoroughly representative of the flora of New England: a collection which shall show the distribution of each species and variety in such detail that from it it will be possible to work out with exactness the natural floral areas of the region. No such herbarium for an extensive area exists in America and no such exhaustive study of a large area has been undertaken with us, but in some parts of Europe very gratifying results have been achieved, and in Great Britain the renewal of interest in such work, already well started by H. C. Watson and two Botanical Exchange Clubs, has recently become very obvious under the leadership of Dr. C. E. Moss of Cambridge University. There is no theoretical reason why we in New England should not bring together such a collection as suggested above; and when this aim is accomplished we shall be in a position to draw from our collections conclusions upon questions of plant- distribution which will be of far-reaching importance. It is too soon to outline with anything but the crudest approximation natural floral areas within our limits; such large districts as the Cape Cod region, the Housatonic Valley, the White Mountains, the eastern coast of Maine, etc. are known in a general way, but we certainly 1 Communicated by the Committee on Field Excursions at the meeting of March 1, 1912. 72 Rhodora [APRIL have not the data by which to determine the exact limits of distri- bution on Cape Cod, for instance, of Lespedeza angustifolia or Panicum oricola; in the Housatonic Valley of Salix serissima or Carex Crawei; in the White Mountains of Osmorhiza divaricata or Lycopodium sitchense; or in eastern Maine of Montia lamprosperma or Comandra livida. Every member of the New England Botanical Club who has aided in the preparation even of Check Lists by states, and all who have taken part in the more detailed work of the Committee on Local Flora realize how lamentably inadequate is the available material in both public and private herbaria; and all of us are cognizant of the constant and too often fruitless appeals from our corps of untiring workers for more data and specimens and for any information what- ever from certain regions. At the last accounting, May 31, 1911, the organized part of the Club Herbarium comprised, besides an encouraging start in Algae, Lichens, Mosses and Hepatics, 43,403 sheets of vascular plants. This figure at first appears large and it might seem that a collection of such proportions is ample for our needs. In fact we might be pardoned for congratulating ourselves upon the vastness of our possessions: the herbarium of the Middlesex Institute, the herbarium of the Metropolitan Park Commission, the private herbarium of the late Herbert A. Young, the Maine collections of F. Lamson Scribner, Elmer D. Merrill, Fred P. Briggs, Miss Kate Furbish and M. L. Fernald; the Berkshire County collections of Ralph Hoffmann, the Marthas Vineyard herbarium of Sidney Harris, and innumerable other collections, including the invaluable New England herbarium of Bryophytes and Lichens of Charles E. Faxon. But valuable as the Club Herbarium has already become, an analysis of its components shows that our present collections are merely a nucleus, about 8 97, in fact, of the material required for an adequate representation of the plants of the six New England states. In the following analysis of the situation column A gives by states the number of mounted sheets of vascular plants in the herbarium on May 31, 1911; column B, the areas of the states; column C, the number of species and varieties of flowering plants and ferns known in each state; column D, the approximate number of species generally distributed in the state; column E, the approximate number of species of local occurrence in the state; column F, the approximate number of species in each area of 100 square miles; and column G, the approxi- 1912] Field Excursions of New England Botanical Club 73 mate number of sheets the herbarium should contain adequately to display the vascular flora of New England. Properly to embody the element of distribution in our calculations the ratio of one specimen of each species to every 100 square miles of area has been used: the figure is entirely arbitrary but has seemed to your committee a con- servative one. The figures given in column F are derived as follows from those of columns D and E. The plants represented by the figures in column E are of varying degrees of restriction. For in- stance, for Massachusetts such plants as the following have been included in this column: Desmodium grandiflorum, widely and almost generally distributed but unknown in the more silicious southeastern areas; Senecio obovatus, frequent in the western third of the state but rare eastward; Betula nigra, known only from the northeastern section; Solidago macrophylla, known only from Mt. Greylock; and obviously all plants of strictly coastal habitats. After considerable tabulation it has seemed reasonable to estimate that the plants of column E, the “local” plants, are found on the average over one tenth of the state. The figures in column F are, then, derived roughly by adding the figures in column D to those in column E divided by 10. In determining the number of species in columns D, E, and F one striking fact, which might readily be overlooked, has been clearly brought out: namely, that the larger the state or the more diverse its conditions the smaller the number of generally distributed species and the greater the number of local plants. Thus our largest state, Maine, with its fertile limestone Aroostook region, its alpine summits, and its sterile silicious southern counties, has only 604 generally distributed species (and the figure may prove too large) while, judging from the statements of ranges given in Brainerd, Jones and Eggleston's Flora of Vermont that smaller but more uniform state has about 950 generally distributed species.
