The flattened, more or less flabellate and mostly dichotomously branched fronds, together with the very constant character of the formation of eight viable eggs in oogonia borne in cavities in the modified ends of the fronds, quite definitely delimit the genus from all other genera of algae ; but the discovery of single characters, or combinations of characters, sufficiently stable to serve in delimiting the multitude of species and forms has been a matter much more difficult of attainment. About twenty-five species and over forty varieties and forms have been previously proposed. From time to time species have been reduced to varieties and to forms, and these have in turn been raised to the rank of species, and the species have been interchanged, according to the conceptions of the different investigators of the group. This has gone on with increasing complexity and there seems never to have been a time when more con- fusion existed in regard to the disposition of the Fucus flora, par- ticularly that of the Atlantic and of the Arctic waters, than the present. The confusion is due to a variety of causes. One of the chief difficulties one encounters in trying to get an understanding of the conceptions of the early writers concerning certain species is the incompleteness of the descriptions, adequate at the time to distinguish fairly well the few forms then known, but wholly inadequate to serve in the separation of species as limited b}^ present day usage. Coupled with the brevity of the descriptions, one often encounters an added difficulty in the nature of poorly prepared, and for the most part, fragmentary specimens preserved as types, if indeed any at all have been preserved. I have quoted some of these early descriptions under proper headings, and have also presented illustrations of some of the few type specimens, which will serve, in some degree, to show the existing state of affairs. Since the days of Linnaeus our conceptions of species have been and still are changing. Formerly larger units were grouped under a single concept, and a few words were sufficient to embody the concept. ^ The general tendency has been to break up the larger units, assigning 00 1922] Gardner: The Genus Fucus on the Pacific Coast 3 to each kind fewer and fewer characters. Today, Avith the coming of the geneticist, the concept of a species is becoming so limited that for practical purposes, if carried to the extreme, it has but little value • nevertheless it cannot be ignored. It is now generally conceded that new kinds of organisms have arisen, and are still arising through permanent modifications appearing in the offspring which produce an individual more or less different from the parent, and that these modifications are heritable and stable. The causes of the modifications that bring about such changes have not yet been assigned. According to Darwin, the modifications are small and when the succession of infinitesimally small modifications in the suppression or development of a structure has proceeded long enough the offspring becomes a species. According to De Vries, the modifications may be relatively great, so that one may readily detect the difference between the parent and the offspring in a single generation. The offspring becomes a new species at once. Pos- sibly both these ideas are correct, but in some groups of individuals con- stituting entities, the forces acting to bring about the changes operate slowly, whereas in others they are accelerated and the resulting changes are marked at once. In either case, it is left to the keenness of the observer to detect the differences. And the difficulty does not end with that ; it can not, in the nature of things, until a specific standard is set up and agreed upon. Darwin never suggested by how much one group should differ from another in order to constitute a species. Another complicating set of factors alwaj^s enters into the situation in a rapidly changing, or species making group, to further the difficulty of detecting the limits of species. The individuals of every generation of all groups of organisms may vary in one or more morphological characters, but these differences are not heritable. Tliis is spoken of as fluctuating variation. The problem which one usually has to deter- mine in placing an individual is whether the dominant character or characters is due to fluctuating variation or to a change which has become fixed. The fluctuating variation may often be much greater than the permanent difference between two species. Thu.s the average width of the fronds of a species of Fticus (a) may be 10 cm., and that of another (&) may be 15 cm. Some individuals in (a) may possibly be wider than 15 cm. and some in (&) may be narrower than 10 cm. The causes of the differences in characters in fluctuating variation may be grouped under two categories, one phj^siological and the other environmental. For example, two Fucus plants of the same lineage may have equal environmental conditions and be equal in initial size, 4 University of California Publications in Botany [Vol. lo but be decidedly different at maturity in a particular character or characters, the differences being due to causes physiological and not yet explainable, and the deviation from the normal not be heritable. Again two plants of the same lineage may by chance get started in different habitats in the same locality and at maturity be quite unlike, e.g.. in size, one typical of the species growing in a belt of optimum conditions for that species, and the other a dwarf merely, due to being removed from such a belt of optimum growth. In passing I may say that the belt of optimum growth is not the same for all species of Fucus. Some species or forms thrive only in the extreme lower littoral belt, others in the middle, and still others in the narrow belt along the extreme high-tide limit. It cannot be argued that the species along the extreme high-tide limit are neces- sarily there by chance and represent dwarf specimens. Fucus evanescens f. rohustus may be found in such a belt extending along the coast for miles w'here no other species or specimens exist, and yet the rock ledges in such localities are continuous from far above the high-tide limit to below the low-tide limit. Specimens of any species may, however, be stranded in the upper tide limits, e.g., on mud flats, and may leave offspring which may develop into seemingly distinct forms. I have seen this demonstrated to my entire satisfaction in tlie case of the so-called nanus forms. These forms are merely transitory. I have seen acres of territory bearing such plants of any species that happened to be growing in the vicinity, the most of which never come to the fruiting period and are always more or less, usually profoundly, distorted and dwarfed. Thus it is quite essential to know the habitat of a plant w^hen attempting to place it. In this paper I am describing three new forms of Fucus seemingly quite distinct from each other genetically, and apparently distinct from all other entities, but which possibly may be only environmental forms. They all fruit abundantly and, to all appearances, from oliser- vations made during only one season, they perpetuate themselves and remain constant. These are forma cuncatus, forma depauperatus, and forma oregoncnsis of Fucus evanescens, found growing in Coos Bay, Oregon. They are profoundly different in shape, size, and color from any forms growing outside of the moutli of Coos Bay. A strong tide sets into the bay and floating specimens may be readily carried for miles in either direction. Tlie determination of the lineage of such forms constitutes a real problem which, in each case, wherever it may arise, can only be solved by experimentation. In a jilace like Coos Bay, the demonstration could fairly easilv be matlc. 1922] Gardner: Tlie Genus Fuois on the Pacific Coast 5 For many years I have observed, in their native habitats, extensive beds of Fiicus growing on our western shores extending from central California to Sitka, Alaska, and have been much confused and deeply perplexed in trying to determine the best disposition to make of the multitude of forms here represented. The range for the genus extends from Oil Port, San Luis Obispo County. California, its southern limit as at present known, into the Arctic Ocean, and is practically unbroken. In the southern portion of the range the problem is comparatively simple, there being but few forms represented. The complexity increases northward, and the optimum for luxuriance in growth of numbers of forms and of individuals seems to be in the general latitude of Sitka. Alaska. I have come to tlie conclusion that we have in this genus an example of extreme plasticity, in which the forces at work breaking up continuity are vigorously active. Plants with new combinations of characters are arising and. to still further complicate the matter, these probably hybridize with one another. For ultra popular usage, a very few species, perhaps four, would thoroughly suffice to include all of the forms of the genus, e.g.. F. serratiis, F. vesiculosus, F. sjyiralis, and F. evanescens. IMorphologically serratus is obviously distinct, vesiculosus is always dioicous. while all others are synoicous. Forms which have been included even under spiralis and evanescens might be confused because of overlapping characters. Such a disposition would doubtless, for scientific usage, meet with hearty disapproval. On account of the nature of the genus, any disposition at present can only be approximate in the face of our vastly incomplete knowledge concerning a variety of points. Without further delay. I am arranging our multitude of forms under five rather comprehensive species, viz.. F. furcatus Ag.. F. nitens nob.. F. edentatus De la Pyl., F. mertibranaceus nob., and F. evanescens Ag. These I have so diagnosed as to make them include all the forms which I have grouped around them, and have designated the group as species 'major. Under each species major, respectively, I , have grouped 13. 0. 5. 6. and 21 fornis which I feel quite convinced are entities, giving rise to others of their kind in successive generations in the same manner as does any other species; however, my investiga- tions may not have been extensive enough as yet to prove this state- ment. These forms I am designating as species minor and, following customary usage. I am calling them formae of the respective species, awaiting further investigation and experimentation to prove the 6 University of California Publications in Botany [Vol. lo validity of their specific rank, or that they represent merely individuals with inconstant and fluctuating characters, due to environmental influences. Historical Review Kjellman (1883, p. 203) remarks as follows concerning some of the numerous forms which he has described: I have set down here the same forms that I have before endeavored to distinguish and to define. They are certainly connected by numerous inter- mediate forms, but they deserve, however, to be mentioned specially, because they show the limits and directions of the variations of the species and differ somewhat with regard to biology and geographical distribution. Yendo (1907, p. 16) has assembled several forms from the Japanese waters and has allied them, according to his conception, with certain of Kjellman 's forms of F. evanescens, at the same time expressing his disbelief in ascribing definite identities to such plants : ' ' Besides the above mentioned formae others might be pointed out. It would, how- ever, be unimportant to add to algological literature more formal names, established on what I regard as invalid forms." I find it not wholly a simple matter to justify the selection of the species major mentioned above as seemingly the most suitable to include our flora as against certain others which might have been selected. T also feel much handicapped in not having had direct contact with more European material for comparison. I have been compelled to rely largely upon descriptions. Most of the earlier collections from our coast were assigned to European species. Two species, however, viz., F. furcatus Ag. (Sp. Alg., 1820, p. 97) and F. evanescens Ag. {loc. cit., p. 92) have been described from the waters of the North Pacific, the former is said to have come from Unalaska and the latter from Kamtschatka. Agardli assigned these localities on the authority of Chamisso, who travelled along our coast in 1816 as far south as San Francisco. Some doubts have arisen as to the localities from which he obtained the material upon which Agardh based his species. Harvey (Bot. Beechey, 1833, p. 163, and 1841?, p. 407) was appar- ently the first to accredit F. furcatus Ag. to the Pacific coast of North America. He based his judgment upon material collected at San Francisco, California, by Dr. Sinclair. I have not seen the specimen, nor have I any further information concerning it, but it seems quite probable, as may be seen later, that his determination was correct. 1922] Gardner: The Genus Fucus on the Pacific Coast 7 J. Agardh (1848, p. 209) quotes Chaniisso's Unalaska specimen and Sinclair's San Francisco specimen under F. furcatus Ag., at the same time reducing F. edentatiis De la Pyl. (1829, p. 84) to synonymy with F. furcatus Ag. This seems to have been the beginning of the con- fusion of the two species which has not, up to the present time, been completely cleared up. Kuetzing (1849, p. 591) gives a brief diagnosis of the species as follows: "F. phycomate linear! enervi piano furcato, digital!; carp- omatibus terminalibus planis 1-1%'' longis, phycomate latioribus." "Ad oras occidentals Americae borealis, ad Unalaschkam, Cali- forniam." In Tabulae Phycologicae, 1860. plate 17, figure II, he gives a diagram of a portion of a plant from " Unalaschka " which shows the receptacles to be 3 to 4 cm. long and very sharply pointed. This figure was probably sketched from a portion of the type material collected by Chamisso and, although it differs considerably from Agardh's figure (Icon. Ined.. pi. 14), it may well represent a more typical portion of a plant than Agardh's. Ruprecht (1851, p. 346) has the following to say concerning F. evanescens Ag. and F. furcatus Ag., mentioned above : Ueber Funis evanescens unci furcatus kann ich jetzt, nacli Einsicht der Original-Exemplare in Chamisso 's Herbarium, ein sicheres Urtheil abgeben. Der erstere ist ein hochst unbedeutende, keineswegs bestandige Form von E. vesiculosa und kommt nieht selten unter den Ocliotskisehen Exemplaren vor; die an den Fruchtzweigen verschwindende Blatt-Rippe bezeiclmet diese Form am wenigsten; Chamisso 's Pflanze stammt von Eedowski, von der Westkiiste der Ochotskischen Meeres, nicht aus Kamtschatka. Fucus furcatus C. Ag. ist eine selbstandige Art, wachst aber nicht bei Unalaschka, sondern in Nord-Californien bei Ross, woher ich neuerdings niehrere Exemplare sah. Von eben daher hat auch, nach meinem Dafiirhalten, Chamisso seine Pflanze mitgebracht; die beigelegte Etiquette mit "Kamtsch?" bezeichnet, beweist, dass er selbst iiber ihren Fundort im Zweifel war. Fucus furcatus J. Ag. (Sp. Alg. I, p. 209) ist ein ganz andere Tang (eine Var. von H. vesiculosa?), als die gleichnamige, in den Icon. Alg. ined. Tab. 14 abgebildete Original-pflanze. Harvey (1862, p. 163) again ascribes F. furcatus Ag. to the Pacific Coast in determining Lyall's collections from Vancouver Island. He remarks {loc. cit.) : "My F. Wrightii from Japan scarcely differs. I fear tliat neither ought to be regarded as other than local varieties of F. vesicidosus, which sometimes, even in Europe, occurs with as narrow fronds. The elder Agardh's figure above quoted," that is, Icon. Ined., pi. 14, "is worthless as a guide to the species described by J. Agardh." Fucus Wrightii is now known to bo a species of Pelvetia 8 Universitu of California Publications in Botaiiij [Vol. lo (cf. Yendo. 1907. p. 20) wliieh again leaves the status of F. furcatus in donbt so far as tho Vancouver Island specimen is concerned. These statements of Ruprecht concerning F. furcatus Ag. doubtless, as pointed out by Kjellman (1883, p. 205) and by Borgesen (1902, p. 465), influenced J. Agardh (1868, p. 40) to describe F. furcatus Ag. and F. edentatus De la Pyl. again as separate species. Kleen (1874, p. 29) subordinates F. edentatus De la Pyl. to F. furcatus Ag. Kjell- man (1883. pp. 204, 205) takes up F. edentatus De la Pyl., accepting J. Agardh 's latest interpretation {loc. cit.) of the distinctness of the two species and reduces Kleen 's F. furcatus to synonymy, remarking in this connection : The identity of the Fucus in question (F. furcatus) occurring on the north coast of Norway, with Fucus edentatus De la Pyl. appears to me to be beyond a doubt. I have not, among the great number of specimens from Norway and the northeastern coast of North America examined by me found any that agree fully with Agardh 's figure of F. furcatus. I have thought best to follow .T. G. Agardh 's later exposition, regarding F. edentatus as specifically distinct from F. furcatus Ag. Borgesen (1902. p. 465) has made the following disposition of the Fucus forms on the Faeroe Islands. He, with Foslie (1886. p. 109) and Rosenvinge (1893, p. 834). takes up the F. inftatus (L.) Vahl (Fl. Dan., pi. 1127) as the species under which should be placed De la Pylaie's F. edentatus, and also reduces Kleen 's F. furcatus, mentioned above, to synonymy with F. inftatus, as well as J. Agardh 's F. furcatus to synonymy with F. in flat us f. edentatus (De la Pyl.) Rosenvinge. Farlow (1881, j). 102) accredits F. furcatus to the New England coast, giving as further distribution, "Northern Europe ; Arctic Ocean ; North Pacific" and cites no. 108 in Farlow, Anderson, and Eaton's Algae Exsiccatae Americae Borealis. Again (1889, pp. 6. 7) he dis- poses of F. furcatus on the xVtlantic coast in the following language: The F. furcatus of Marine Algae of New England is without doubt the same as F. edentatus of Newfoundland, formerly united with F. furcatus Ag., of the North Pacific, a species to which was also referred a Fucus of the northern coast of Norway. Later tlie two species were kejit distinct by J. G. Agardh, and Kjellman in the Algae of the Arctic Sea referred the so-called F. furcatus of Norway and Greenland to F. edentatus where our common New England alga also belongs, although the Fucus furcatus of our west coast may perhaps be the same as the original F. furcatus of C. A. Agardh 's Icon. Tncd. Acceptance of tlie ideas set forth by Foslie. Farlow. Rosenvinge, and Borgesen would (juite effectively eliminate 7*'. furcatus Ag. from the Atlantic and Arctic waters. It remains now either to reestablish or to eliminate^ this species entirely. I ])ropose to reestablish i1 with 1922] Gardner: The Genus Fucus on the Pai-ific Coast 9 certain emendations, using as a basis for my decision Ruprecht 's state- ments {loc. cit.) supported by Farlow's contention {loc. cit.) that furcatus belongs primarily to the Pacific coast of North America. Borgesen (1902, p. 465) recognizes the priority of Agardh's furcatus (1820) over De la Pylaie's eclentafus (1829), but rejects the name furcatus on the ground, as he says, that "the specimen of this species which C. Agardh described was — judging especially from his figure — a small, poorly developed one (apparently a transitional form to f. distichus) .'' '' The type specimen of F. furcatus is in the Herbarium of J. G. Agardh. no. 00279 (Type!) Unalaska, Ex. Herb. C. Ag., accord- ing to Professor Setchell. I have reproduced Agardh's figure on plate 1, figure 1. and it certainly is not a characteristic portion of any species of Fucus, but represents, as I think, a proliferous portion of a plant. I have seen many specimens of proliferations similar to the one represented by Agardh (cf. plate 2), taken from dried herbarium specimens collected by Setchell at Fort Ross, the probable type locality. It seems to me that the evidence is sufficiently ample to warrant the assumption that Agardh 's delineation, poor and uncertain as it is, refers to a plant on the California coast. Basis of Classification I am using as a fundamental distinguishing character of F. furcatus as a species major the presence, usually, of a large number of cavities in the fronds which are completely closed. These are, I suspect, what J. Agardh (1868, p. 38) refers to under " Cryptostomata immersa saepe numerosa, plurima diu clausa. " I have investigated the origin of these structures and find that they originate as do the conceptacles and ordinary cryptostomata, as shown by Bower (1880). A surface cell near the growing point in the terminal depression breaks down and the cavity is formed as described by Bower, but unlike the con- ceptacles and the cryptostomata no ostiole remains. The cavity is completely arched over, and no paraphyses develop. This process appears to be an evolution in the direction of reduction. To these cavities I am applying the term caecost&mata, as suggested by Professor Setchell. to distinguish them from the true cryptostomata with ostiole and paraphyses. In F. furcatus f. typicus, as I am limiting that species, they are \evj abundant, up to four hundred and fifty in each square centimeter, and there are no cryptostomata. In certain other forms of furcatus there are a few cryptostomata perfectly formed very early. The caecostomatal character seems quite effectually to mark off 10 University of California Publications in Botaiuj [Vol. 10 a distinct group, the distribution of whose members extends as far north as Sitka, Ahiska, with the southern limit in San Luis Obispo County, California. Along with this character is usually found a decided olive green color. Fucus nitens refers to a group of plants growing in San Francisco Bay, which seems not to fit in well with any other described species. It doubtless is an offshoot of the furcatus group, and very probably hybridizes with it. The decision in the selection of edentatus as against inflatus for the specific name seemingly best suited to certain of our narrow forms is based upon the study of the original descriptions and illustrations of the type specimens of each species. Fucus inflatus dates back to Flora Lapponica, of Linnaeus, 1737. The diagnosis as given by Linnaeus in Species Plantarum, 1753, p. 1159, is: "Fucus fronde bifida; laciniis ovato-lanceolatis inflatis apice divisis. " This will suffice in part for any species of Fucus that has been proposed, just as well for one as for another. Through the kindness of Dr. M. A. Howe, I have a habit sketch made by him of two small parts of plants in the Linnaean Herbarium which, according to Dr. Howe, is all that is left to indicate Linnaeus' conception of this species. These small bits are sterile and Dr. Howe remarks, "The enlargements, to which it owes its name, are possibly inflations which have been flattened do^^'n in pressing, but I find no certain evidence of this in the Linnaean specimen." Thus neither the description nor the specimens seem to me in the least adequate to give one even an approxi- mate idea as to the concept of Linnaeus regarding this species. Vahl, in Flora Danica, plate 1127, gives a diagrammatic sketch and a brief diagnosis showing his conception of the species. The sketch is cer- tainly of a plant quite different from that of Linnaeus. Of late j^ears there has been as great conf vision in the use of the term inflatus as in the use of furcaius. Foslie (1886, p. 109) proposes F. inflatus (L.) Vahl for certain narrow forms. Kjellman (1890, p. 11) adopts the name for a group of plants which he first separates into two groups, a Finmarkicus and (3 Nordlandicus, under which he describes nine different forms. He left no illustrations and made no attempt to show their relation to other described forms. Rosenvinge (1893, p. 834) uses the name inflatus to include F. edentatus De la Pyl., F. evanescens Ag., and F. linearis (Ed. De-Toni (1895, p. 195) accepts the group as proposed by Kjellman. Borgesen (1902, p. 465) uses the term inflatus to include certain Faeroe Island plants which he designates as 1922] Gardner: The Genus Fucus on the Pacific Coast 11 formae edentatus, distichus, and linearis. Setchell and Gardner (1903, pp. 280, 281) used the term in flatus to include certain plants in the Puget Sound region which were placed under the forms edentatus, linearis, and filiformis of this species. The type of F. edentatus De la Pyl. is in the herbarium of the Museum of Paris. Dr. M. A. Howe has examined and photographed this type specimen and through his courtesy I have received a print of the negative, which I have reproduced on plate 60, figure 1. I have examined dried specimens from the north Atlantic coast of a relatively narrow form, which are smooth and black on drying and free from caecostomata, which seem to me to correspond with the description and illustration of the type of edentatus. Several of our forms which have been previously associated with F. inflatus seem, on close com- parison with these eastern specimens, to belong with the edentatus lineage rather than with the much more vague inflatus lineage, and I am placing them in accordance with this view. I am using the term edentatus as a species major to include mostly narrow, smootli, and glossy forms, almost black on drying, practically free from caecostomata and with few cryptostomata. There are remaining certain northern forms which do not seem to fit in well with any of these groups. They have more or less mem- branaceous fronds, with no caecostomata, are usually decidedly yellowish in color, have the cryptostomata most abundant on the terminal and subterminal segments and these crj'ptostomata protrude on drying. These I have grouped under the species major which I have designated as memhranaceus. In treating of the Fucus flora of the northwest coast of North America, Setchell and Gardner (1903, p. 281) adopted Fucus evan- escens as a satisfactory name to include most of the forms then known in that region. This species thus is given the widest range in distribu- tion of all the described species, since this name ha.s been applied to plants of both shores of the North Atlantic and of the North Pacific as well as of the Arctic oceans. One of the chief characters upon which this species is based, viz., the vanishing of the midrib in the terminal and .subterminal segments, is as fluctuating as any other character. It may be seen on plate 35 that the midrib extends to the very tips of the segments. This plate represents a plant from Spitz- bergen determined by J. Agardh. Three fragments of plants, no. 132622 of the Herb. Univ. Calif., from the same region collected by Kjellman likewise show the midrib quite distinctly. Plate 1, figure 2, 12 University of California ruhlications in Botany [Voi.. 10 represents the original figure of Agardh and shows very little midrib in the terminal segments nor in other parts of tlie frond. ^\\ own experience with this character is that it cannot be relied upon as having verj^ pronounced diagnostic value, except in a few cases. The type locality is said to be Kamtschatka and, according to Setchell, the type specimen is in the herbarium of J. Gr. Agardh, under no. 00299, with a query. Kjellman has described ten forms of evanescens and reduced J. Agardh 's F. hursigerns to a form of the same species. Stroemfelt (1886, p. 35) added f. dendroides. De-Toni (1895, pp. 201-203) accepts all these forms as valid. Setchell and Gardner (1903, p. 283) added two more. ]\Iost of Kjellman 's forms have been recognized with some degree of certainty in the northern portion of the range considered here. The plants so listed, however, seem almost invariably to be more robust than those of Kjellman 's finding. On the whole, the species as understood in Europe, seems to me to be the best suited to include the most of the forms of Fucus growing in the North Pacific region, having more or less coriaceous fronds for the most part robust. with a brownish or yellowish color, wath relatively few cryptostomata. Diagnostic Characters In attempting to diagnose our forms, I have made use only of the gross morphological features. I think, however, that it would be quite within the bounds of possibility that histological characters could . be made use of effectually in determining limits. The shape and size of the oogonia and antheridia vary considerably, but I have not carried the study far enough to determine ^v'hether a fixed difference may be present and detectable, or whether the difference may be due simply to fluctuating variation. The only satisfactory way to prosecute such study is by the use of fresh or fixed material. The following characters have been used in rendering the diagnosis in this work : The lioldfast, in all cases, is a solid, somewhat fibrous disk, larger or smaller according to the species and to the nature of the substratum and the environment, which serves to anchor the plant. The plants growing on tlie open coast, exposed to heavy surf, usually have the most robust lioldfasts. Those plants growing on wood in (]ui('1 waters usually have smaller, poorly developed ones. Plants growing under the latter conditions usually do not persist long. The stipe is a term ratlnr loosely applied in this group. Strictly speaking, it should apply to that portion of Ihc frond between the 1922] Gardner: The Genus Fucus on the Pacific Coast 13 holdfast and the first forking, varying in different species from one centimeter to five centimeters in length. As the plant grows older the alae wear away, more or less, and the midribs among the segments, or branches, thicken; flat at first, they become more nearly cylindrical and virtually become a part of the stipe. The length of the stipe and its degree of flatness are characters of considerable value in deter- mining species. The term segments is understood to apply to those portions of the frond between each forking. Characters of the segments which are of morphological value in determining the species are the general shapes, the most prominent of which are linear and cuneate, thickness and width of the alae, and the extent of the development of the midrib. The nature of the terminal segments is often of pronounced value. The growing point is located at the base of a flattened, more or less crescent-shaped pit of considerable depth at the outer ends of the terminal segments. They are thus situated back of what appear to be the ends of the segments. The nature of these terminal depressions is of some diagnostic value. Beceptacle is a term used to designate the metamorphosed free ends of the terminal segments, for the purpose of developing the reproduc- tive organs, oogonia and antheridia. These organs are borne along with sterile filaments, the paraphyses, in cavities, the conceptacles, scattered in various ways over the surface of the receptacles. The receptacles vary much in shape, even on the same individual, as well as on different individuals and on different species. Some are com- planate and possess little mucilaginous substance, others are much swollen and filled with the same substance and still others are inflated with gases. Receptacular characters, though variable, are of con- siderable value in determining species. Cryptostomata, w^hen applied to the genus Fucus, is a term that has been applied to certain cavities scattered promiscuously, or arranged more or less definitely, over the whole frond except the stipe and the holdfast. They are not confined to this genus alone, however, ])ut have been more thoroughly investigated in Fucus than in any of the other genera. They appear in other members of the Fueaceae, and also in several genera of the Laminariaceae. The cavities may or may not have sterile, hyaline hairs, paraphyses, in greater or less profusion and, when present, extruding at times through an opening at the top called the ostiole. These paraphyses disintegrate sooner or later, and even the whole cryptostomata may disappear entirely as the lower parts 14 University of California Puhlications in Botany [Vol. 10 of the front metamorphose. The phylogeny, functions, and develop- ment of the cryptostomata have been the subjects of considerable dis- cussion and investigation among algologists. It is not my purpose here to go into an extensive discussion of the literature on these subjects. A few statements, however, may be of service in this con- nection. Bower (1880, p. 36) briefly reviewed the literature that had been published on the investigations of the subject of the cryptostomata up to that date, bearing particularly upon their origin. Oltmanns (1904, 1905) has given a much more exhaustive account of opinions and investigations, including his own, on all phases of the subject. Regarding the phylogeny and functions of these organs, the investi- gations up to the present time seem to have been too meager to warrant any satisfactory general conclusions. That which seems to me to be the most satisfactorily assignable function of the paraphyses is one suggested to me by Dr. Setchell, first mentioned by Reinke (1875, p. 2.30), viz., their connection with nutrition. Reinke compares them to root hairs of the higher plants, serving to increase the absorbing surface. In whatever species they occur, they originate and are most vigorous in meristematic tissue, either in ephemeral or in perennial species. They would thus seem to be homologous to root hairs in the higher plants, exposing a greater absorbing surface at the time and in the place of greatest need for food, soon disappearing after having served their purpose. So far as the genus Fucns is concerned, the investigations of Bower {loc. cit.) seem definitely to have settled the question of the origin and development of the conceptaclcs as well as the crypto- stomata. He shows that they originate just back of the growing point, in the depressions at the apices of the fronds, by the failure of a single surface cell to divide horizontally, and its subsequent disintegration. From this beginning he carefully traces and figures the enlarging cavity resulting, and the differentiation of the reproductive organs and sterile hairs. I have verified the results of Bower's investigation so far as the initial step in the formation of these organs is concerned. Having frequently noticed forms of Fucus, particularly from the region of Puget Sound southward to the southern limits of its dis- tribution, in which tlie cryptostomata were deep-seated, completely closed, and destitute of paraphyses, I was prompted to investigate their origin with a view to determining the use to which this character might be put in placing the species. Several genera of the Fucaceae 1922] Gardner: The Genus Fiicits on the Pacific Coast 15 have the eonceptaeles promiscuously distributed over practically the entire frond. In others, e.g., Fucus, Pelvetia, the reproductive struc- tures are limited to the metamorphosed ends of the segments. The cryptostomata in the genus Fucus are so intimately associated with the eonceptaeles, both being the same in their method of origination and similar in their form, as to make it seem quite logical to conclude that they are degenerated conceptables. Indeed Bower has so considered them, speaking of them as "incomplete sexual eonceptaeles." Adopt- ing this line of reasoning one may readily conceive that it is only a step further in the line of reduction evolution to produce a plant in which none of the cryptostomata develop paraphyses and all remain completely arched over, leaving no ostioles. Fucus on the west coast of the United States abounds in forms having structures of this nature. Such cavities I have designated caecostomata as distinguished from cryptostomata, and I am using them as one of the distinguishing characters of a species major, viz., Fucus furcatus (see above, p. 9). The next stage in reduction would be the complete elimination of both caecostomata and cryptostomata, and approximately this condition exists in the species major, Fucus cdentatus. The color character is of considerable value in determining species. This character, however, is subject to a certain amount of variation and cannot be solely relied upon. The color of an individual may vary with age and with exposure. In dense clusters of plants the lower portions have a more intense color than the upper part. All specias are darker on drying than in the living state, and the color distinction between species may be more pronounced and constant in the dried specimens than in the living plants. The habitat of a plant cannot be said normally to be a specific determinant, though a knowledge of the normal habitat of a plant, if markedly different from that of another plant, may assist in estab- lishing to a certainty the belief in the entities of two closely related forms. Fucus evanescens f. rohustus is never to be found growing outside of a narrow belt along high-tide limit. F. mcmhranaceus f. latissimus inhabits exclusively the lower littoral limit. If there were nothing in gross morphology to distinguish these two species, this fact alone would lend plausible support to the belief that the two are distinct entities, each with a separate lineage. 16 University of California Ptiblications in Botany [Vol. 10 Fucus furcatus Ag.

The specimen is only a small portion of a plant. It is mature, considerably worn and battered, and has comparatively few caecostomata. The distribution is probably to be referred to f. typicus, but it is desirable to consult other specimens of the distribution before deciding definitely. This form is abundant on the California coast, but less common toward the north, being supplanted by numerous other forms. It reaches its optimum growth in localities where the surf is only moder- ately active. In such situations it attains its greatest height, not infrequently specimens attaining a height of 4.5 dm., but when on boulders exposed to a heavy surf, it remains much shorter, is more arborescent, the alae wearing away up to the last segment. The illus- tration on plate 3 is of the former state, and that on plate 2 is from an exposed situation at Fort Ross, California, presumably the type locality for the species. I have selected this specimen as the type because it shows the proliferating habit Avhich seems to be the character of the specimen illustrated by Agardh (see plate 1, figure 1). There is considerable individual variation in the width of the segments. The dimensions given in the diagnosis cover a very large majority of individuals in a bed of plants, but occasionally wider or narrower plants may be found. They fruit abundantly, only an occasional segment remaining sterile to continue the growth and fruiting in the next season if the plant persists. Most of the segments fruit simul- taneously, and the height of the fruiting season is in June and July ; some receptacles may, however, be found at any season of the year, as is usually the case with all the species of the genus. The specimens after desiccation readily yield a copious amount of mucilaginous substance on being revived, either with fresh or with salt water. It was hoped that the copious secretion of mucilage might be traced to the caecostomata which are so abundant in this species, and that this definite function might be assigned to them, but it has not been possible to connect these structures with this function. 18 University of California Publications in Botany [Vol. lo Fucus furcatus f. angustus f. nov.

The only other definite locality in which this form has been detected is Cattle Point, at the south end of San Juan Island, Washington (Gardner," no. 2352g). This locality is particularly rich in forms of Fucus. There is an intermingling of the waters flowing among the islands to the north and east, which have a varied Fucus flora, with the waters from the Strait of Juan de Fuca and the Straits of Georgia, washing the shores of land to the west and north, which have a some- what different Fucus flora. The shore of the south side of Cattle Point is exposed to a swiftly flowing current and to the action of swells from the Pacific Ocean, through the Strait of Juan de Fuca. Around to the north side of the point the shores are affected but little by the action of the surf and tides. Fucus furcatus f. anguMus seems closely related to F. in flat us f. edentatus of Borgesen. I draw my conclusion after having compared our plants with a specimen of Borgesen 's from the Faeroe Islands in the Herbarium of the University of California, no. 99176. I have represented this specimen on plate 20. Borgesen 's specimen lias a more pronounced midrib and the segments are more decidedly cuneate. The color is not so dark as the color of our specimen.

This form is remarkable for the abundance of receptacles it produces on a single plant. Plate 5 was made from a portion of a plant that had approximately five hundred and fifty receptacles. It is also rather unusual that so many of the segments should fruit at the same time as is the case in this form. Not a single segment remained sterile in the above mentioned plant.

He states that some of the receptacles are up to 7 cm. long, being much longer than an>- which I have seen. The narrow fronds with prominent midribs and the very dark color make this form clase to certain narrow forms of cdentatiis, but the absence of cryptostomata and the small caecostomata relate it to the furcatus group. It has the least number of caecostomata of all the forms with which I am familiar, certain specimens being nearly free from them. In this character the form approaches very closely to the edentatus group. 1922] Gardner: The Genus Fucics on the Pacific Coast 21 Fucus furcatus f. nigricans f. nov.

On drying it is smoother than either of the above mentioned forms, the caecostomata not standing out so prominently. The type (plate 9) was collected in May, and, although fruiting abundantly, may possibly be immature, judging from the number of blunt receptacles.

The two forms often grow intermingled, but may readily be distinguished by differences in size and color, forma luxurians being much more robust, and of a lighter brownish or yellowish color in the upper parts, par- ticularly the receptacles. The southern limit of the form, as of all forms of Fucus so far as is at present known, is Oil Port, San Luis Obispo County, California. The northern limit has not yet been deter- mined, but it probably extends as far north as Cape Flattery, Wash- ington, where there is an intermingling of several forms whose limits have not yet been determined. It merges into forma elongatus from Coos Bay, Oregon, which I have segregated, as is illustrated on plate 9. The plants persist for several years, are in fullest fruit in early summer, although some receptacles may be found at any season of the year. Always a portion of the segments resulting from forking remains sterile. These continue to grow and branch, forming segments for the next year's receptacles, while the other segments fruit and disintegrate, leaving the midrib of the segment as a pointed projection. The plants do not seem to proliferate. Many of the alae split obliquely to the midrib, giving them a serrate appearance. Plants growing at Pacific Grove, California, which I have referred to this form, are subject to this habit quite generally. I have noticed also that in this locality the plants have a decided tendency, toward the end of the growing season of the receptacles, to establish several meristematic regions on the ends of the receptacles, some of which produce quite prominent and pointed projections with a tendency to becoming vegetative, as many as ten having been observed on a single receptacle with a common wide base.

I have placed it in the- furcatus group on account of the color, dark olive green to dark olive brown, and the presence of cryptostomata in abundance. Many of the terminal segments are very broadly ovate, almost stipitate, on account of the narrowing of their bases, producing broad rounded angles between the segments (plate 12). The growing points differ from those of all other forms observed on our coast, the apices of the segments being rounded and smooth, but with slight incon- spicuous slits to indicate the position of the growing point. The receptacles, particularly when young, have the pronounced and distinguishing character of spreading very widely from each other at their bases, in some instances standing at right angles, or even more, to each other. Many segments have the character of reducing their Mddth at each forking, the terminal segments forming the stipelike portion bearing the much wider receptacles. Fucus furcatus f. rigidus f. nov.

Most of the specimens of this latter collection have shorter receptacles with wider base and with most attenuate and divergent apices. According to my conception of this form, its phylogenetic position • is between forma latifrons and forma luxurians. From the former it differs in having a more rigid cartilaginous structure, in having nar- rower and more strict segments, and in having longer and narrower receptacles. From the latter it differs in having more strict and more nearly linear segments and longer and narrower receptacles. 1922] Gardner: The Genus Fucus on the Pacific Coast 25 Fucus furcatus f. latifrons f. nov.

A close relationship seems to exist between this form of F. furcatus and F. evanescens f. magnificus. The color, eaecostomata characters, and the rigid, more or less cartilaginous consistency of the fronds are characters that belong to the furcatus group. The width of segments and particularly the fruiting habit (see under F. evanescens forma magnificus) are very similar to those of that form. The eaecostomata vary much in number. In some specimens they are practically absent, while in others there may be seventy-five or perhaps more to the square centimeter. They are mostly large, deep-seated and inconspicuous on drying, except by transmitted light. Specimens with but a few eaeco- stomata usually have a few small cryptostomata. Fucus nitens sp. nov.

San Francisco Bay, Cali- fornia. Type, Gardner, no. 2165 (Herb. Univ. Calif., no. 201150), Sausalito, California. This relatively small group of Fucus plants, although very much circumscribed in its distribution, seems so distinctly marked off in its combination of characters from other species, particularly from those in the southern portion of the range covered in this paper, that it is worthy of specific rank. The combination of characters that dis- tinguish this species consists of the following: relatively long and narrow, smooth and glossy fronds, strict, even overlapping habit of the terminal and subterminal segments, the dark brown color with yellowish receptacles at maturitj^, absence of caecostomata, and the cryptostomata, when present, are inconspicuous. Its affinities with F. edentatus may possibly be traced, but they seem too remote to merit much serious consideration. The somewhat coriaceous consistency of the fronds suggests relationship in that particular with certain forms of evanescens, but on the whole it inclines more, in its consistency, to the cartilaginous consistency of F. furcatus, under which I have con- sidered placing it. I have observed this species with considerable care throughout all seasons of the year for the last twenty years. In its typical habitat it seems thoroughly fixed as a distinct entity. The chief association of plants extends along the rocky shore from the harbor at Sausalito to Point Cavallo, a distance of about two miles. There are a few smaller groups at other points in the Bay, but in all of these localities the waters are more quiet than along the shores of the Golden Gate out to the Pacific Ocean. In the localities where they are found they are never intermixed with any forms of F. furcatus, the only other known species on the California coast. No plants of F. nit ens have ever been found growing on either side of the Golden Gate for some distance inside of the entrance. From Point Cavallo to some distance west of Lime Point, an interesting association exists for which I have no way of accounting, except by hybridization between these two species. A variety of intermediates exist. There are yellowish brown plants with inflated, yellowish, bi-, tri-furcate receptacles like those in the quiet waters of the Bay, but filled with hundreds of small caecostomata characteristic of F. furcatus; and there are plants with flat receptacles and olive green, cartilaginous fronds but which are smooth and glossy and wholly lacking in caeco- stomata, characters belonging to F. nitens. These and other combina- 28 University of California Publications in Botany [Vol. lo tions of modifications lead me to believe that these two species must hybridize in this locality. Both species are synoicous and hence it would be very difficult to carry out definite hybridizing experiments. Fucus edentatus De la Pyl.

The two groups of plants were, however, in slightly different altitudes in the belt, and were not indiscriminately intermixed. AVhen the two sets of plants are dried, they are easily distinguishable by the smoothness of the segments, forma hesperius being smooth and usually shining, while forma angustus is rough, due to caecostomata, and is of a duller color. 1922] Gardner: The Genus Fiicus on the Pacific Coast 29 Forma Jiesperius seems closely related to or is at least very similar to a narrow, smooth, dark colored form that grows on the Atlantic coast of the United States, which has been referred to different species by different authors. There is a good specimen of it contributed by Howe, under no. 150, to the Herbarium of the University of California, no. 77184, labelled F. edentatus. The specimen in Professor Setchell's copy of Farlow, Anderson, and Eaton's Algae Exsiccatae Americae Borealis, no. 108. is almost identical with Howe's specimen, but is referred to F. furcatus. I have examined no. 119 of Hauck and Richter's Phykotheka Universalis, labeled Fucus edentatus De la Pyl. and contributed by Collins, from ]\larblehead, JMassachusetts. This specimen seems to be identical with the two above mentioned. It is my opinion that all three collections should be referred to F. edentatus De la Pyl.. and, judging from the figure and description of the type as quoted above, very clearly represent the typical form of the species. None of the Atlantic specimens referred to above have eaeeo.stomata. Fucus edentatus f. divergens f. jiov.

The fronds average somewhat wider, more robust, the angles between the segments are very much wider and more rounded, and the receptacles mostly deeply bifurcate or single, widely diverging. The average width of the segments is about 10 mm., but a few specimens were found with extremely narrow segments, about 3 mm. Tliese were profusely branched, with wide angles, and small diverging receptacles. Also a few specimens were found with the characters of the form, but were 15 mm. wide. These few specimens I have considered as the extremes in individual variation in this particular character. 30 University of California Fuhlications in Botany [Vol. lo Fucus edentatus f. costatus f. nov.

The plants distributed in the Phycotheca Boreali-Americana as no. 926 were from the type locality, but were taken from the upper limit of the belt of distribution when the tide was well in. They are considerably battered and worn away, and thus cannot be said to be in typical condition. Plate 23 represents a young plant, the type, mostly in typical vegetative condition. Plate 24 represents two plants, showing the extremes in variation in the width of the fronds. Speci- mens as narrow as the narrower sterile one on the plate are rare, and at some future time may have to be considered as distinct. The illustrations were all made from dried material. This form resembles closely F. evanescens f. angnsitis Kjellm. in width of fronds, and was so referred as is cited above. Subsequent to the above publications, material of that species, collected and deter- mined by Kjellman on the Vega expedition, has been received at the Herbarium of the University of California (no. 132699). The lack of a prominent percurrent midrib, almost complete absence of crypto- stomata, and especially the very small rece|>tacles of Kjellman 's material, point out unmistakably that our plant is of a different lineage. 19-2] Gardner: The Genus Fucus on the Pacific Coast 31 Fucus edentatus f. acutus f. nov.

The very dark color on drying, the absence of caecostomata, and the sparseness of cryptostomata in this form seem amply sufficient to ally it with the edentatus group rather than with the seemingly more imperfectly defined group infiatus.

Till., 1868, pp. 41, 42, pi. 3). I have seen the specimen of Kjellman's F. evanescens f. hursigera, also collected at Spitzbergen. The plants of Agardh and of Kjellman are undoubtedly of the same lineage, and they are probably allied more closely to the evanescens lineage than to any other. The Sitka plants under consideration, on the whole, and particularly on account of size and consistency, seem closer to the memhranaceus group than to the evanescens group.

It was growing in abundance on a small rocky island in front of the Sitka harbor. It grew well up in the littoral belt, exposed to the heavy action of the surf. The plants growing in the most exposed places are quite arborescent in character, the alae wearing away up to the last two or three segments, leaving the much thickened midrib. In depressions and less exposed situations, the alae were usually wider and remained on the fronds longer. The plants in this group become exceedingly mucilaginous on being soaked out after a thorough drv'ing. 34 University of California Puhlications in Botany [Vol. lo Fucus membranaceus f. obtusus f . nov.

In many specimens the midrib is quite indistinct. The cryptostomata characters are quite as much of the one group as of the other. I am placing it provisionally with the former group largely on account of the predominance of inflated receptacles, on the mem- branaceous character of the fronds, and on the color. Two forms of Fucus were found growing at Point Defiance, rep- resenting an interesting case in distribution. Forma limitatus occupied for the most part the extreme upper portion of the littoral belt, and grew on logs and boulders.

On my second visit to the same place in July, 1917. 1 located a large bed containing thousands of plants growing along the extreme low-tide level, and I was able to procure a number of good fruiting specimens, although the summer season does not seem to be its best fruiting season. This form may be readily distinguished from all others by its width, being the widest form in the vicinity, its membranaceous alae, its very dark lower portion, and usually yellowish upper portion, and by its much crisped habit of growth. Some of the plants of this species collected by G. B. Rigg at Kadiak Island are the widest specimens of Fucus that have been reported, some of the fronds measuring over seven centimeters in width.

After considerable observation in several different localities, I have come to the conclusion that f. nanus cannot be considered as a distinct form of any one species, but is in reality composed of a mixture of dwarfed plants of whatever species or forms of species that happen to 38 University o\ California Publications in Botany [Vol. lu inhabit the region. These dwarfs are always found on mud flats, salt marshes, and ({uite commonly at the mouths of rivers and smaller streams where such mud flats and marshes may occur. At extreme high tides, frequently, a great abundance of plants, of whatever species of Fucus happens to be growing in the vicinity, are thrown up and lodge among other plants that grow there. The spores are shed and, being in a moist place, they germinate and persist for a longer or shorter time. The plants are always much gnarled and distorted, and rarely come to fruit. At the mouth of the Indian River at Sitka, Alaska, is a favorable place for the study of such dwarfed plants. There are many different forms of Fucus growing in the vicinity, and a great many plants are constantly being cast up on the gradually sloping flat at the mouth of the stream. There are enormous numbers of dwarfed plants in all possible stages of development and distortion. One can come to no other conclusion than that these are dwarfed plantvS, that they are the offspring of whatever plants may by chance be thrown up there, and that their identity can not be traced, growing as they do in such unusually abnormal environmental conditions. Among these abnormal environmental conditions may be mentioned, first, inconstancy in the food supply due to frequent changes in the salinity of the water, resulting in great differences in the osmotic tension; .second, great variation in the temperature— the fresh water from the river flows over them more or less, and its temperature is near the freezing point a large part of the year; third, variation in light intensity; and fourth, exposure to muddy water. Under such conditions it is rather a biological wonder that any forms of the genus persist at all, yet many small specimens produce seemingly viable spores. All of our forms on the Pacific coast are synoicous. This makes the matter of tracing the ancestry of dwarfs slightly more difficult than if dioicous forms were present, without resorting to the experimental method by cultures. The study of these dwarfed forms of brown seaweeds has been pursued quite extensively by Baker (1912'i and by Baker and Bohling (1916). They traced the ancestry of certain forms and produced dwarfs experimentally. Some of these forms they claim to he fixed entities. They did not, however, try the experiment of producing sporelings from the dwarfed forms and transplanting them to a normal habitat to ascertain if they reverted at once to the oi-iginal form. 1922] Gardner: The Genus Fuciis on the Pacific Coast 39 Fucus evanescens f . cuneatus f . nov.

One becomes somewhat exasperated in attempting to deal with such forms as the one above. Ordinarily it might be considered a depau- perate form of some other well developed and characteristic form. There w^ere several square rods of fruiting plants like those represented on plate 38 growing on very gently sloping sandstone near high-tide level. There were no other plants growing near, and there was seem- ingly no reason why, from the standpoint of anchorage, they should not grow much farther down in the littoral belt. The reduced size could not be due to superabundance of fresh water, for several much larger forms were found growing from three to six miles farther up the bay where the water is much less saline. ]\Iany plants have w^ell- developed mature receptacles. Its general characters seem to favor its being grouped with F. evanescens, although it will fit practically as well into the edentatus group. I am placing it with the former until more can be learned of its life history. Fucus evanescens f. ecostatus f. nov.

This form seems to be definitely fixed, and does not appear to grade into any of the forms that are found growing outside of the bay. More investigation, however, may show that it is only a depauperate form of some definite species; on the other hand, it may prove to be a distinct species. It varies considerably in size and width of the fronds. The receptacles, though mostly pointed, are at times wide and blunt ; at least there are specimens growing in the same habitat Avhich have the same general characters but differ only in the character of the receptacles, and in such cases the segments are generally wider. They are connected, however, by almost impercept- ible gradations. The size of the plants may be somewhat influenced by the su.bstratum, mostly wood and soft sandstone, neither of which is suited to holding plants for a very great length of time. They usually do not persist in such localities beyond a single fruiting period. If the vanishing of the midrib is to be considered as having any diagTiostie value, this form eminently belongs with the evanescens group. The midrib in some specimens is scarcely discernible in any part of the frond, and in all it vanishes in the terminal segments. Fucus evanescens f. oregonensis f. nov.

The plants 1922] Gardner: The Genus Fucus on the Pacific Coast 41 are smaller, segments narrower and regularly dichotomous instead of subsecund, and the receptacles are shorter and blunter.

The plants were repeatedly branched, fruiting pro- fusely, had a relatively large and strong holdfast and stipe, and varied from 7 cm. to 15 cm. in height. Some of the plants of Setchell and Lawson, referred to above, are onlv 4 cm. his^h. those of Townsend are 42 University of California Publications in Botany [Vol. 10 15 em. to 18 cm. high. Stroemfelt does not mention the height of the type in his diagnosis, but his illustration, natural size, is 14 cm. high. The size of our plants, their narrow contorted segments, the character of the receptacles, the large firm holdfast and dendroid habit, agree so well with the description and figures of Stroemfelt as to leave little room for doubt as to the affinity of the two. Comparison with the type material may, however, show that the two sets of plants are distinct, as Stroemfelt does not mention the cryptostomata nor the caeco- itomata, nor does he mention the color, which is very striking in our plants. As the plants hang on the rocks after the receding tide, the shape, appearance, color, and abundance of receptacles reminds one of settled swarms of Italian bees.

Growing on rocks in the middle littoral belt. Sitka, Alaska. Type, Gardner, no. 3997 (Herb. Univ. Calif., no. 201163), July. 1917. The distinguishing characters of this form are absence of con- ceptacles from a complete margin of the receptacle, particularly of the rounded terminal portion, coupled with extreme sparsity of both cryptostomata and caecostomata. It is difficult to decide to which species this form is most closely related. It has evident affinities with Fucus evanescens Ag. and with F. spiralis L. Its color and consistency, coupled witli the slightly vanishing midrib in the terminal segments, seem to ally it with F. evanescens, but, if allied with this species, it would be through f. den- droides of Stroemfelt as its nearest relative. I have not seen the type nor any authentic specimens of f. dendroides, but since no one has questioned the validity of the form as belonging to F. evanescens, I am retaining it as such and grouping certain Alaska specimens with it. The narrow, rather long, considerably contorted and profusely branched 1922] Gardner: The Genus Fucus on the Pacific Cmst 43 fronds, the blunt and somewhat fusiform receptacles, and the dendroid habit certainly suggest its close similarity with f. dendroides. How- ever, I am inclined to keep it distinct on account of its decidedly more robust habit, the practical absence of cryptostomata, the much lighter color than that of the other forms within our region which I have placed with f. dendroides, and the distinctly marginal receptacles. Fucus spiralis, although, for modern usage, imperfectly des.'cribed by Linnaeus, has relatively recently been taken up by a number of algologists to include certain forms on both the European and the American shores of the Atlantic. Kjellman (1883, p. 202) definitely recognized it as a species, segregating, as new, f. horealis. In 1890, however, he changed his conception of the species and named it F. Areschmigii, segregating f. nana. De-Toni (1895, p. 207) recognized F. spiralis as a valid species and reduced Kjellman 's F. Areschougii to synonym. Borgesen (1902, pp. 472^77) followed De-Toni, and in a clear discussion reduced also F. platycarpns Thuret to a form of if'', spiralis. Howe (1905, p. 581), after having examined the speci- mens in the Linnaean Herbarium supposed to represent Linnaeus' conception of F. spiralis, agrees with Borgesen 's conception with regard to the validity of F. spiralis, considering as the typical form no. 23-4 of Collins' distribution from IMaine in the Phycotheca Boreali-Amer- icana sub F. Areschougii, and recently, in a letter to me, he states that he is inclined to place under this species most of the American plants which have previously passed for F. platycarpus of Thuret. Cotton, in Clare Island Survey, 1912. has kept up the name for certain forms in that locality. It seems thus to be quite well established as a species; the limits of variation, however, and the exact number of forms which should be grouped with it, have not yet been agreed upon. So far as I can learn, the name has not yet been used to designate any Pacific Ocean forms. Forma marginatus, under discussion, has some characters which might well link it with F. spiralis. It has the char- acteristically twisted segments in the upper part of the fronds, and the margined receptacles figured by Borgesen {loc. cit.), but the specimens of spiralis to which I have had access usually show an abundance of cryptostomata emitting fascicles of relatively long paraphyses, decidedly different in this respect from our plants. They also have shorter and more rounded receptacles and alae wider in proportion to the length of the segments. 44 Universifij of (Utlifornia I'lihlirations in Botany [Vol. 10 Fucus evanescens f. flabellatus f. iiov.

The majority of the plants seem scarcely mature at this season of the year, but enough of them were selected that appeared mature to be fairly certain that the measurements given for the receptacles are sufficiently accurate. The distinguishing character of the form is the pronounced fan-shape of the whole frond when spread out, and par- ticularly of groups of segments, due to the secund method of branching. The cryptostomata are relatively few and inconspicuous, and there is approximately the same number of caecostomata ; thus in this char- acter the form is on the border line between F. evanescens and F. furcatus. Probably the tendency is in the direction of the degeneration of these organs. The other characters, however, seem sufficiently well represented to ally it with F. evanescens.

I doubt if the form should be considered as extending farther south than Juneau, Alaska, where it intermingles with forma magnificus.

There are three fragments of the form in the Herbarium of the Universitj^ of California, no. 132622, from Spitzbergen Islands, determined by Kjellman. These are represented on plate 36 and, although authentic, they do not entirely coincide with Kjellman s descriptions and type specimens as shown on plate 47. Apparently they are not representative specimens of this form. Plate 48 represents a form growing in the middle littoral belt at Juneau, Alaska, that coincides very closely with Kjellman 's diagnosis and with plate 47 of his type specimen of forma pergrandis. A striking feature of the Juneau plants, however, is that practically every segment fruits at the same time. The Butler and Polly plant referred here is peculiar in being completely free from both caeeostomata and cryptostomata. The Johnson plant referred here might be considered a very large specimen (45 cm. long) of F. evanescens f. cornutus, and the Kjellman plants have sterile segments. The simultaneous fruiting of the seg- ments in the Juneau plant would indicate a much shorter fruiting season than in such forms as f. magnificats, in which only a few of the segments are fruiting at any one time. It would be of much interest to know how constant and reliable these characters of fruiting or non- fruiting of segments are as an aid to the determination of species.

The writer collected 48 University of California Publications in Botany [Vol. lo it at Sitka in June, 1910, when it was in full fruit, and at Friday Harbor in July of the same year. The type and the two cotype speci- mens have all of the receptacles complanate, and are apparently immature (plate 49), but in the other collections mentioned many of the receptacles are much inflated (plate 50). The species is one quite free from mucilage as compared with other species of Fucus growing in the same localities but much lower down in the littoral belt. It seems to have become fixed as a form, and has the distinct habit, or character, of being able to persist in the upper two feet of the littoral belt, in which habitat it is necessarily uncovered the greater part of the twenty-four hours each day. It inhabits rock ledges, either steep or sloping, yet it is strictly confined to the upper, very narrow, belt. Its fronds are lighter and somewhat more fibrous than those of any other form.

So far as my observations extend, this form seems to be the mo.st abundant of all the forms included in the above mentioned region. It varies quite widely in the shape of the receptacles as shown in plate 51. Some receptacles are simple, others decompositely furcate, many quite obtuse, others decidedly acute, but all are definitely delimited and swollen almost to the bursting point with mucilaginous substance. The segments are wide and foliaceous, not narrowing at the forkings, and the tendency to the strict habit of growth often makes them quite contorted. One of the distinguishing characters is the sparsity of receptacles maturing at any one time. This habit, marked in only a few of our forms, should receive more study in the field. My opinion is that the 1922] Gardner: The Genus Fucus on the Paxiific Coast 49 fruiting season extends over a much longer period than in most of the other forms. In the summer season, when I have observed them, one may find on the same individual receptacles varying from completely mature, to others just beginning to form, and many more sterile seg- ments. The fronds fork. One branch of the dichotomy metamorphoses directly into a receptacle and the other continues to grow, and it in turn may fork one or more times without fruiting. This makes the mature receptacle appear to be lateral in origin, whereas in reality it originates just as all others do. This seems to be the condition prevail- ing in Thuret's F. platycarpus. Plate 16 in the Etudes Phycologique well illustrates this condition, but illustrates also another condition which does not seem to occur in f. magnijicus, viz., that the suppressed fruiting segments are alternate, whereas in f. magnificus they are secund. I do not know how regularly the condition prevails in F. platycarpus, but this condition is too constantly prevalent in f. mag- nificus to be overlooked as a diagnostic character.

Tilden 's no. 235 seems to belong here, although the specimen in Professor Setchell's copy of her American Algae is only a fragment and just beginning to produce receptacles. The distinguishing character of this form is the decompositely furcate receptacles, often widely divergent. As many as eight divergent apices have been observed with a common base. The fronds are decidedly flaccid and dissolve rather readily in fresh water after being dried. 50 Umversitjj of California Puhlications in Botany \yo\.. lo Fucus evanescens f. longifructus S. and G.

A cotype specimen of this very distinct form is illustrated on plate 54. and it features the distinguishing characteristics very well. It is unlike all other forms in the extremely long, linear-lanceolate, regular complanate receptacles, frequently spreading or recurved at the apices. In external appearance it approaches F. furcatiis f. rigidus, but that form has an abundance of caecostomata, the recep- tacles usually more decompositely furcate, and it is more cartilaginous. No. 5186 from Juneau is placed here with some doubts. If it should be placed here, it should be considered at the lower limit of variation in size. Fucus evanescens f. cornutus Kjellm.

Comparison with a photograph of the type (cf. plate 55) and with a small portion of the type specimen seems to make it fairly certain that the two specimens collected by Albin Johnson, and cited above, are correctly placed, although they are much larger in all parts than Kjellman 's description calls for. ]\Iore study of material in the northern waters is highly desirable to make certain this determination. In neither the type nor the other material referred to is the cornute habit very pronounced. Fucus evanescens f. typicus Kjellm.

Kjellman 's type specimen of this form is illustraed on x>late 56, and represents a plant considerably smaller than the plants which I 52 University of California Publications in Botany [Vol. lo have allied with it from the Alaskan waters. No. 5122, in particular, is much more robust than Kjellman's description calls for. The receptacles are much longer and wider, but this may possibly be accounted for by difference in age. The plants collected by Rigg are smaller and more nearly coincide with the description. This plate shows Kjellman's plant to be about 10 cm. high, possessing distinct midribs in many of the segments, and to have relatively small recep- tacles. There is a plant in the Herbarium of the University of Cali- fornia, sheet no. 132618, contributed by Kjellman and collected on Spitzbergen in "1872-73," labeled in Kjellman's handwriting, ^'Fucus evanescPMS A^.,''^ which is almost a duplicate of the type specimen mentioned above. There is also a plant in the same herbarium, col- lected in 1868 from the same locality and determined by J. G. Agardh as F. cvanesccns Ag., whose fronds are about twice as wide as those of the Kjellman plants (cf. plate 56). Otherwise all of these three collections of plants are very much alike. The type specimen of F. evanescens Ag. is in the herbarium of J. G. Agardh at Lund under no. 00299. It has been examined by Professor Setchell, who states that the plant is slightly smaller than the plant referred to in Setchell and Gardner's Algae of Northwestern America, under f. typica, from Harvester Island. Alaska. This plant is in the Herbarium of the University of California under no. 99139. It differs only slightly from the wide form of F. evanescens from Spitzbergen, mentioned above, having more numerous, larger, and better developed receptacles. There is much greater disparity of size between this specimen and Kjellman's f. "typica" than there is between Kjellman's f. "typica" and his f. "limitata." If we admit the specimen determined by J. G. Agardh from Spitzbergen as belonging with f. typica Kjellman. then the Harvester Island specimen which is so close to it had probably better be allied with it at present, until more is known of the forms from that island. However, it also seems very close to Kjellman's f. " corniita," but has wider fronds and receptacles than the type specimen of that form. 1 am referring here a series of plants collected on Kadiak Island, Alaska, by G. B. Rigg, no. 100. These plants are only slightly wider than the tj'pe specimen of Kjellman, and liave numerous well developed receptacles. They appear to be the closest in all «liaracters to the type, and I am taking them to be the best representatives of f. typicus thus far discovered in Pacific Coast waters. 1922] Gardner: The Genus Fucus on the Pacific Coast 53 Fucus evanescens f. rudis Kjellm.

Plate 30 is labeled "Con- stantinea rosa marina," but has in addition a small plant of Fucus. This plant has long, acuminate receptacles. Plate 25 of the same work, to which Kjellman probably refers, is labeled Fucus vesiculosis and has decompositely furcate receptacles with long, acuminate apices. The plants referred here by Setchell and Gardner (1903, p. 282) have the characteristic receptacles referred to above. Comparison with a photograph of Kjellman 's type specimen hardly bears out his con- clusion regarding the illustration in Postels and Ruprecht. The fronds are reduced in width above each forking. Some of the receptacles are relatively wide, others are very narrow, and those of Kjellman 's type, which I have seen, are very blunt. Some doubts must be entertained as to the limits of this form. I am referring here plants from Orca and Skagway, cited above, as more nearly coinciding with Kjellman 's type. 54 Vniversity of ('oliforma Publications i)i Jiofani/ [Vol.10 Fucus evanescens f. irregularis Kjellm.

A photograph of the type specimen indicates to me that this form, segregated by Kjellman on Bering Island, is hardly to be considered an entity but rather a battered and distorted plant of some other form. To my knowledge it has not been recognized since its original discovery ; bnt if a valid form, it is quite likely to occnr on the North American side of the Pacific Ocean, hence I am inclnding it here as a possibility.

The only material of which T am aware that has previously been referred to this form since its establi.shment by Kjellman is that referred by Setchell and Gardner {loc. cif.) from Norton Sound, and the same material, two small fragments of plants, is again referred 1922] Gardner: The Genus Fuciis on the Pacific Coast 55 here to the same form, though with some doubt. It is evidently a small form and, according to Kjellman, grows in the sublittoral belt, an unusual habitat for small forms, or even other forms outside of the Arctic regions. It may be noticed from the illustration (plate 59) that the Norton Sound specimens have a decided habit of growth which is not very common among the forms of the genus, viz., one of the mem- bers of a dichotomy develops into a receptacle, while the other con- tinues to grow and forks one to several times before the receptacle of the original dichotomy matures and disintegrates. This makes the receptacle appear to have developed laterally. The illustration (plate 58) of the type specimen does not show this character, prac- tically all of the segments fruiting simultaneously. More study of this character is highly desirable. Fuscus evanescens f. contractus Kjellra.

Kjellman does not mention in his description of this form the decided and sudden difference between the width of the segments and the receptacles which they bear. This difference makes the receptacles appear stipitate, since they are over twice as wide at the base of the segments. Presumably this is the character upon which the form is based. 56 University of California Publications in Botany [Vol. lo No. 5652 (Herb. Univ. Calif., no. 99101) from St. Michael, Alaska, quoted above, is as near the type as could be desired in every particular. The plants are about 10 cm. high, thus representing the upper limits in size as stated by Kjellman. The plants under the other numbers referred to are all larger in all parts than the measurements given by Kjellman, but they seem too closely linked to the type to warrant separation without further study of quantities of material in the field. There is not the sudden widening of the receptacles in any of the latter forms as in the type. The receptacle character seems more closely allied to that of f. microcephalus.

This form of evanescens, first described by Kjellman, has not been clearly identified with any specimens from our region, but is here included because of its close resemblance to certain of our forms, and hence the probability of its occurrence within our waters would seem to warrant its inclusion. Yendo (1917, p. 16, pi. 1, fig. 1) identifies a plant of the Japanese waters with this form. Setchell and Gardner (1903, p. 284) also identified plants from East Sound and Fairhaven, Washington, with this form, and specimens from East Sound were distributed in Collins, Holden, and Setchell 's Phycotheca Boreali-Americana, no. 926. On comparison of our plants with a sheet of plants in the Herbarium of the University of California, no. 132699, collected on the Vega expedi- tion near Tjapka and contributed and labeled by Kjellman, Fucus evanescens f. angustus, it seems best to change the determination and to place our plants under Fucus edentatus f. costatus. under which a detailed account is given. The plants illustrated by Yendo difi'er decidedly from the Kjellman specimens referred to above, particularly in the size of the receptacles and the prominence of the midrib. It may be doubted whether this form really extends so far south on 1922] Gardner: The Genus Fucus on the Pacific Coast 57 either coast of the Pacific Ocean as was previously supposed, but its occurrence farther north may well be expected. Fucus ceranoides f.

In conclusion, it affords me much pleasure formally to acknowledge my sincere gratitude to Professor W. A. Setchell for encouragement and many valuable suggestions in the preparation of this work, to Dr. M. A. Howe and Dr. Carl Skottsberg for prints of photographs of type specimens, and to Mr. T. S.

The early publications of Bentham (1829, 1837), of Gray (1863), and of Watson (1876) dealing with American species are inadequate to meet the present needs, as the Avork of later students has resulted in the accumulation of much material, and in additions to the number of described species. The somewhat heterogeneous assemblage of American species is in many respects similar to the Old World group, but has been treated in diverse ways by the various authors. An Enumeration of the North American Loti was published by Greene in 1890. Although com- paratively few species have been described since, the need of further investigation is still great, as Greene's diagnoses are commonly brief and practically ignore the variations present within many of the species. Geographical Distribution The New World Loti comprise a large group of species, limited, almost without exception, to western North America, extending from British Columbia to Mexico and Lower California, but, in one case, reaching as far south as Chile. Only one native species has been cited for the eastern, and one for the middle United States, the latter being abundant in the Pacific Coast states. More species are found growing in California than in any other one state. In the northern part of the state occur species common to British Columbia, Washington, Idaho, and Oregon ; in the southern part and in the islands off the coast appear many species which occur also in Lower California ; and in the eastern and southeastern parts, especially in the regions of the Mohave and Colorado deserts, are found several species whose range extends into Nevada, Arizona, and Mexico. The Old World species of Lotus have a widespread geographical distribution. They are of most common occurrence in those parts of Europe, Asia, and Africa adjacent to the Mediterranean Sea, but they appear also in northern Europe, southern Africa, and montane Asia. In Australia the genus is represented by one indigenous species. 1923] Ottley: A Revision of the Calif ornian Species of Lotus 191 Development of the Generic Concept of the Genus Lotus IN Its Kelation to the New World Species The American species first described were referred to the Old World generic type Lotus. They were L. sericeus Pursh, in 1814, and L. suhpinnatus Lag., in 1816. The third species was described by W. J. Hooker as L. pinnatus in 1829. Later that same year, Bentham redescribed this species and named it Hosackia hicolor Dougl. making it the type of the new genus Hosackia. At the same time he described two other species for his new genus, Hosackia decumhens and Hosackia parviflora, and transferred Lotus sericeus of Pursh to Hosackia, assigning to it the binomial Hosackia purshiana. In stating his reasons for regarding the American plants as generically distinct from the Old World genus Lotus, Bentham says of Hosackia hicolor Dougl. This plant has much of the habit, as well as the inflorescence and fruit of a Lotus, to which Dr. Hooker. has referred it in the Botanical Magazine; but independently of the characters which may be drawn from the position of the alae and the capitate stigma, the pinnate not ternate leaves, and the absence of the large foliaceous stipule of Lotus — characters which appear to be of importance among most of the Leguminosae * * * perhaps alone suffice for the adoption of the genus HosacMa proposed by Mr. Douglas. Bentham found, however, as he became acquainted with an increasingly larger number of American species, that the characters which he had regarded as distinctive for Hosackia did not hold for all; and in 1837, retaining the name Hosackia for eleven species, he referred five {Lj. suhpinnatus Lag., L. macraei Benth., L. micranthus Benth., L. sericeus Pursh, and L.f unifoliolatus Hook.) to the genus LotiLS and created for these the section Microlotus characterized by plants having one-flowered peduncles and exstipulate leaves of three to five leaflets. Bentham and Hooker (Genera Plantarum, 1865) reduced two of these {L. macraei Benth. and L. unifoliolatus Hook.) to synonymy, retained the other three in the section Microlotus of the genus Lotus, and referred twenty -five other American species to the genus Hosackia. Torrey and Gray (Flora of North America, 1838) used the name Hosackia for all the American species, as did Gray (Synopsis of the Species of Hosackia, 1863). Watson (Botany of California, 1876) followed Gray in recognizing the genus Hosackia and referred to it all the species belonging to the group under discussion. These three works, however, differ as to the number of sections and as to the 192 University of California Publications in Botany V^'ou 10 taxonomic position of certain species. Torrey and Gray {op. cit., 1888), divided the group into four sections: Euhosackia Benth., Drepanalohus Nutt. (later in the same work changed to Syrmatium Vogel), Microlotus Benth., and Psychopsis Nutt. MSS. Gray (1863) grouped the species within the three sections, Euhosackia, Microlotus, and Syrmatium, and Watson (Botany of California) followed Gray in this usage. Gray and Watson reduced the five species of the section Psychopsis Nutt. as given in Torrey and Gray {op. cit., 1838) to one species, Hosackia purshiana Benth., and assigned this species to the section Microlotus. The section Microlotus of Hosackia as given in Gray 's Synopsis and in the Botany of California differs from Bentham's Microlotus of Lotus by the omission of a single species; this species, Hosackia parvi flora Benth. {Lotus micranthus Benth.) having been assigned by Gray and Watson to the section Euhosackia. On the other hand, the section Microlotus in the Flora of North America contains not only Hosackia parviflora Benth. and Hosackia suhpinnata T. & G. but also Hosackia strigosa Nutt. with its near relatives, and Hosackia maritima Nutt. Torrey and Gray believed that these latter species show a complete transition from the single- flowered species of Microlotus to the umbellate species of typical Hosackia. In 1890 Greene remanded all the New World species to the genus Lotus under four sections corresponding to the following genera of earlier authors : Acmispon Raf ., Anisolotus Bernh., Hosackia Benth,, and Syrmatium Vogel. In Engler and Prantl (Die Natiirliehen Pflanzenfamilien) all the American species are referred by Taubert to the genus Hosackia. On the other hand, some of the more recent authors have not only discarded the generic name Lotus for the New World species, but have treated the several groups {Hosackia, Acmispon, Anisolotus, and Syrmatium) as distinct genera. In general, each author's usage has differed from all other treatments in regard to the generic concept and also in regard to the limits ascribed to the species. The various assignm-ents of the species to Lotus and its segregates may be summarized as follows : 1. All the American species have been referred to the Old World genus Lotus. 2. All the New World plants have been treated as a distinct genus under the name Hosackia. 3. The American species have not only been regarded as wholly distinct generieally from the genus Lotus of the Old World, but have 1923] Ottley: A Revision of the Calif ornian Species of Lotus 193 been segregated into several genera : Hosackia Benth., Acmispon Kaf., Syrmatitim Vogel, and AnisoJotus Bernh, 4. The genus Hosackia has been recognized as including the greater number of American species, while at the same time certain of the sjjecies were remanded to the Old World genus Lotus. Reasons for Remanding the New "World Species to the Old World Genus Lotus While the North American species have been assigned to two or more distinct genera, the species which form the most well-marked group are those which have been referred to the genus Syrmatium (subgenus Syrmatium of this paper). In general they are char- acterized by small indehiscent arcuate legumes which with the per- sistent calyx and pedicel are deciduous at maturity. These characters, however, with the exception of the deciduous fruit, are not constant for all the species assigned to the group. The legumes of some may be tardily dehiscent, as has been observed in the case of Lotus eriophorus Greene (Syrmatium eriophorum Heller), while two of the species, Lotus glaher Greene (Syrmatium glabrxim Vogel), and Lotus leucophyllus Greene (Syrmatium sericeum Greene), have straight or slightly falcate legumes. The leaves, inflorescence, and flowers possess only those characters which have their counterpart in many of the species of the groups Hosackia and Acmkpon. The deciduous fruit is therefore the only distinguishing character which is constant for the Syrmatium group. Shall we recognize such a character as of sufficient importance to justify the formation of a new genus? Of this Greene (1890) says: "Since the jointed pedicels and deciduous fruiting calyces of for example the Lag opus subgenus of Trifolium are not to be of generic import, neither may they be so treated in this group of Lotus which has been called a genus under the name Syrmatium." A consistent treatment of the remaining species would demand recognition of at least five generic groups: (1) Hosackia Benth. including those species with stipules, (2) Acmispon Raf. represented by L. americanus Bisch. with its three-foliolate leaves, (3) Anisolotus Bernh. embracing L. suhpinnatus Lag., L. humistratus Greene, and L. denticulatus Greene, all having seeds and corollas that differ slightly from those of the other American species, and (4 and 5) two additional genera separated b}'' characters of corolla and stigma. 194 University of California Publications in Botany [^^oi.. 10 If the Californian species were grouped according to the method outlined above they would segregate into five or six genera, largely on the basis of single characters which are of doubtful generic importance. The appearance of intergrades also presents an objec- tion. For example, Lotus oMongifolius Greene var. cupreus of the subgenus Hosackia, with its short leaves of three to seven leaflets, its small flowers with petal claws approximate, and its few-flowered umbels (mostly 1 to 3), more closely resembles some of the species within the subgenus Acmispon than it does the other species of the subgenus Hosackia. Lotus micranthus Benth. is another of these troublesome species and has been disposed of in different ways by the various authors. It has been suggested that the Old World genus Lotus is used in too restricted a sense and that it should be extended to include several other closely related genera. With reference to this point, Greene (1890) states: "Lotus Tetragonolobus, Lotea, Krokeria and Dory- cnium of the Old World along with Acmispon, Anisolotus, Hosackia, and Syrmatium of the New World are even more naturally of one genus than are the various subdivisions of the one genus Trifolium as now everywhere received." If we accept the view that the New World species are not sufficiently diverse to be referred to different genera, but constitute a natural generic group, we have next to con- sider whether the American species are generically distinct from the Old World genus Lotus, as used in the broader sense indicated above, or whether they form merely a part of it. As a result of careful study of the literature and of available plant material, we find that the American species as a group possess no constant characters of inflorescence, flower, or fruit which dis- tinguish them generically from the European Loti as conceived by Greene. The most nearly constant character that has been used in separating the two groups relates to the leaves. The typical leaf in the Old World species is pinnately compound with three leaflets at the apex of the rachis and two at the base of the leaf, close to the stem, simulating stipules. The leaves of the New World species are far from uniform in the number and arrangement of the leaflets. They vary from pinnately to subpalmately compound with the leaflets ranging in number from three to fifteen or more. According to the usage adopted in the present paper distinct stipules are always present in the subgenus Hosackia, while in the subgenera Acmispon and Syrmatium the stipules are reduced to glands. The leaves of 1923] Ottley: A Eevision of the Calif ornian Species of Lotus 195 three or four species of the subgenus Acmispon resemble very closely those of the typical European Loti. Leaves with three leaflets at the apex of the rachis and one at the base near the stem are of common occurrence in Lotus sul)pinnatus Lag. and in L. humistratus Greene, while in L. americanus Bisch. leaves with one terminal leaflet and two lateral ones near the stem are the rule. Moreover, certain Old World species which differ in leaf character from the Lotus type in the restricted sense possess leaves similar to those occurring in certain species of the American representation ; for example, the short petioled subpalmate leaves with gland-like stipules of Dorycnium suffruticosum Villars correspond closely to those of Lotus ivrightii Greene of the American species. Therefore, since characters of generic importance are lacking in inflorescence, flower, and fruit, and since the distinctive leaf characters in addition to being merely vegetative are weakened by the presence of exceptions and intergrades, we have remanded the American species to the Old AYorld genus Lotus in its broadest sense. Acknowledgments Grateful acknowledgments are due those who have assisted me in this work. Dr. Willis Linn Jepson of the University of California, under whose careful direction the work was carried on, has been most helpful in giving suggestions and criticisms and has kindly permitted me to use his research material, his library, and his manuscript notes relating to the types of Hosackia and of North American Loti pre- served in the Kew Herbarium. These notes contain not only descrip- tions of the types but also comparisons of many of the types with specimens in the herbarium at the University of California and have been of invaluable aid to me in determining the specific limits of certain species. Mr. Frank W. Peirson of Pasadena, California, very generously assisted me in making field observations and in collecting specimens of those species of Lotus growing in southern California. For the privilege of examining herbarium material I am indebted to those in charge of the herbaria of the University of California, Leland Stanford Junior University, Pomona College, the California Academy of Sciences, the Gray Herbarium of Harvard University, and the United States National Museum. To these and to all others whose services or interest have contributed toward the preparation of this paper, I wish to express my heartiest thanks. 196 University of California Publications in Botany [Vol. lo SYSTEMATIC TREATMENT Explanation of Certain Terms Used in the Text Calyx tube should be interpreted to include the short hypanthium at the base of the flower. Length of flower refers to the distance between the tip of the wings and the apex of the pedicel. The terms Lower Sonoran, Upper Sonoran, and Transition refer to life zones in which the different species herein treated are found growing.

Dry slopes in the Coast Ranges and in the Sierra Nevada from Shasta County to Mariposa County. ]\Iarch-July. The plants of the Sierra Nevada represent an extreme form which was named Hosackia macro nth a by Greene. In this large form the leaves, peduncles, flowers, and fruit (legumes 2 to 7 cm. long, 3 to 5 mm. wide) always approach the upper limit in size. The triangular base of the long-subulate calyx teeth is more pronounced and the soft hairs at the sinuses between the calyx teeth are more abundant than in the plants of the Coast Ranges. The typical form occurs in the Coast Ranges but is not so abundant there as is the variety miitahilis. Distribution Map 3. L. grandiflorus Greene with L. rigidus Greene.

It has been suggested that Hosackia wrightii Gray (Lotus wrightii Greene) is too near H. puheruJa Benth. (L. j^uberulus Greene), to be a distinct species; but if my assumption, that the specimens in the Herbarium of the U.S. National Museum from Mexico cited below are typical L. puherulus Greene, be correct, the two are clearly dis- tinct. The leaves of L. puherulus Greene are not in the least sub- palmate but are strictly pinnate with 4 to 8 (3) acute linear leaflets. The majority of the plants in the U.S. National Herbarium, from Arizona and New Mexico have subpalmate leaves and seem more closely akin to L. wrightii Greene than to L. puherulus Greene. The Mexican plants cited below are assumed to be typical of Hosackia puherula Benth., since Bentliam's type of H. puheruJa came from near Zacatecas. Mexico.

Annuals, ascending or decumbent, with many slender branches arising from the crown of the root ; herbage and pods appressed-hirsutulous ; leaves 1.5 to 2.5 cm. long, with 6 to 10 leaflets scattered along the flattened rachis, one nearly at the base of the leaf and only about one-half the size of the terminal leaflet ; leaflets acute, linear-oblong, those of the lower leaves often cuneate-obovate and obtuse; peduncles exceeding the leaves or shorter, the lower ones 1-flowered, those higher up on the stem 2 to 3- flowered ; bract when present mostly of one leaflet ; flowers 5 to 10 mm. long; pods straight or slightly curved at apex, 2 to 3 cm. long, 2 to 2.5 mm. wide, the beak short and straight ; seeds many, granulose, notched at the hilum, quadrate in surface view; in cross-section rounded oblong, not more than 1 mm. in diameter. Common in sandy situations near the coast from San Francisco south to San Diego County, Distribution Map 4. January-November. The small-flowered plants agree with L. ruheUus Greene. I do not find the seeds of these distinguishable from those of the large-flowered form of L. strigosus Greene, either by shape of seed or by markings of seedcoat, as claimed by Greene.

Pacific Coast states east into central United States. Distribution Map 5. May-October. A very variable polymorphic species of wide distribution. L. americanus has been divided into several different species, notably by Heller, on the basis of variation in pubescence, number and size of flowers, length of peduncles, and habit. After a careful study of the various forms in the field and of duplicates of Heller 's types we conclude that the group is essentially a unit. With the exception of Heller's Acmispon glabratus with its relatively short and broad calyx teeth, no qualitative distinction, except that of habit, has been found on which to separate the group into the different divisions.

More or less common in the Sonoran throughout the state. Often found growing side by side with L. humistratus Greene. Distribution Map 6. March-October. Upon comparison of certain Calif ornian specimens of the U.C. Herbarium {TIaU 3841, Brewer 360, 1166, see localities) with plants at Kew Herbarium of Lotus suhpinnatus Lag. collected in Chile, Dr. Jepson found that, in general, the Chilian plants were more pubescent, the leaflets were narrower and were four in number, not five as is often the case with the Californian plants. After a careful study of a large number of plants from different parts of the state and a consideration of the diagnosis of the Chilian type by Lagasca and of the description given by Hooker and Arnott for the species as represented by plants collected at Conception, Chile, I have come to the conclusion that the Californian representatives should be retained within the species. They show as great variation among themselves as with the South American plants. The South American plants are also variable, as may be seen from a comparison of Hooker and Arnott 's description Avith that of T^agasca. The extent of variation is no more than one might expect to find in a species with such a wide range of distribution. Localities. — Near Trinidad.

Low thickly-branched perennials with leaves and flowers reduced in size and number until the plant seems to be little more than a mass of slender stiff green branches; few appressed hairs on the stem, somewhat more on the growing tips and calyces; leaves ternate, the tiny leaflets borne on a short petiole; leaflets elliptical, obtuse, 2.5 mm. long or less; flowers solitary or occasionally in pairs, slightly over 5 mm. long ("2 mm." according to Orcutt), borne on short peduncles; calyx one-half as long as the flower, with broadly linear teeth shorter than the tube; legume curved, 1-seeded, 5 mm. long ; seed slightly curved. Range exceedingly limited. Reported only from Mountain Springs and caiions in or near Colorado Desert, San Diego County. Dis- tribution Map 8. April. Careful field observations of this species should be made to determine whether or not it intergrades with L. scoparius. The description given above is taken from Orcutt 's type of Hosackia haydoni, but does not agree with Orcutt 's diagnosis as to size of flower.

Low brown much- branched suffrutescent perennials, suberect to decumbent ; herbage sparsely covered with short appressed hairs, becoming glabrate with age ; leaflets 3 to 5, rounded-oblanceolate, not over 6 mm. long ; umbels few and peduncled ; calyx teeth short-triangular, not at all subulate, the midvein broad and inconspicuous ; legumes short, fat, and arcuate, 1 or 2-seeded. Of infrequent occurrence on dry hills from Mt. Tamalpais south- ward near the coast to San Luis Obispo. Distribution Map 8. April- July. This species should not be confused with the form of L. scoparius appearing in San Diego County, which has triangular calyx teeth with a vein running through the center and ending in a subulate point. The aspect of L. jimceus easily distinguishes it in the field from L. scoparius with which it is occasionally found growing. Localities. — Mt. Tamalpais, K.

(pi. 78, figs. 15-22), More decum- bent, the stems more delicate and often wiry ; pubescence more abundant ; peduncle usually exceeding the leaves and bearing a bract of one leaflet. Distinguishable from delicate plants of L. henthamii Greene by its terete arcuate fruit and its short-triangular calyx teeth. — North Coast Ranges from Marin County to Mendocino County. Distribution Map 8. May-July (October). There is apparently no qualitative character to separate this variety from L. junceus Greene unless the manner of growth be con- sidered as such. The length of the peduncle and the presence or absence of a bract can hardly be of specific value, as umbels with or without a bract may occur on the same plant, while the length of the peduncle is a variable character also. The pubescence is in kind that of the species, only more abundant, and the amount varies within the variety.

Distribution Map 9. April-November. The typical varietal form appears at low altitudes in sandy washes near the coast. As it passes inland to the higher altitudes, as in the San Jacinto Mountains (Distribution Map 9), it approaches L. douglasii Greene var. nevadensis in general appearance, but may be distinguished from the latter by the spreading hairs of the young 1923] Ottlejj: A Eevision of the CaUfornian Species of Lotus 233 steins. There is no technical character separating L, heermannii Greene from L. eriophorus Greene and the former, therefore, is con- sidered by the writer but a variety of the latter, a variety with smaller flowers and less pubescence. It is not always possible to distinguish clearly between the species and the variety as occasionally small- flowered plants appear to have the pubescence of the species and large-flowered plants have the general aspect of the variety. The limit of 5 mm. for length of flower in the variety is arbitrarily chosen and holds true only in general.

NOTES ON A COLLECTION OF NEW ZEALAND HEPATICAE BY WILLIAM HENRY PEARSON University of California Publications in Botany Vol. 10, No. 4, pp. 307-370. plates 83-108^ S Issued June 9, 1923 LIBRARY WeW YORK BOTANICAL OARDE>>» NOTES ON A COLLECTION OF NEW ZEALAND HEPATICAE BY WILLIAM HENRY PEAESON Since Archibald Menzies collected Hepaticae in New Zealand in 1791 (the specimens are in the Manchester Museum), a large number of species have been added by various collectors and named by Mitten, Stephani, Colenso, and other authorities. These are all enumerated by Stephani in his Species Hepaticarum and Supplement up to 1918. Colenso published as new a great many species in the Transactions of the New Zealand Institute, most of which have been examined by Stephani, and a revision of the same published in the Journal of the Linnean Society for 1893. I have not been able to find that any New Zealand Hepaticae have been published since 1918. The present collection was made by Professor Setchell in 1904. Although small, it contains some interesting species and its examin- ation has afforded me much pleasure. There may be errors in judgment, where I have not had the opportunity of comparing the specimens with the original types, but I have been very fortunate in being able to do so in many cases, for the Manchester Museum is very rich in types of New Zealand species from the Carrington and Spruce collections. Although Stephani records many New Zealand species from Tas- mania and Australia, he intimates in one of his notes that he is of the opinion that the Hepatic Flora of New Zealand is almost endemic, and with this opinion I agree. The type specimens of all species described as new are deposited in the Herbarium of the University of California and duplicates of the same, as far as the specimens would allow division, are also deposited in the Manchester Museum in England. 308 University of California PuhUcations in Botany [Vol. 10 Marchantia Setchellii sp. nov. Plate 83 Dioicous. Medium size; dark glaucous green in color; densely caespitose. Fronds dicliotomous, ligulate, equal breadth, cross-section plano-convex, 20 to 25 cells thick at the middle, cortical cells two laj^ers, dark-colored, similar in size to the inner, margin of fronds often recurved, marginal cells smaller than others. Scales light purple, oval, rotundate or obtuse, distinctly dentate, teeth short; appendages deep purple, lanceolate-acuminate or ovate-acuminate, dentate, teeth often long and hamate; cells oblong-quadrate. Stomata numerous, round or oblong, three tiers of cells high, 8 marginal cells, inner quadrate. Cupules shallow, dilated, fringe dentate, teeth 1 to 3 cells long. Dimensions. — Fronds 1 to l^/o inch long; 2 to 3 mm. wide; .5 mm. thick at the middle, margin .1 mm. thick, marginal cells .01 to .02 mm. ; median scales .4 mm. X .45 mm., .35 mm.

Habitat. — Slopes near Waimangu, North Island, W. A. Setchell, 1904, no. 160. Type, Herb. Univ. Calif., no. 213707. Observations. — Although the specimens received from Setchell are all sterile, I have no hesitation in considering this a new species. Evans, in The American Species of Marchantia (Trans. Conn. A. & S., vol. 21, 1917), notes the specific value of the appendages; in this species they are very distinct from any of those of any other species recorded from New Zealand. The onlv one that has somewhat similar ones is 31. papillata Raddi, a South American species, although 31. platycnemos Schwaegr. from the Falkland Islands has been doubtfully referred to this species. I have not had the opportunity of examining any specimens of 31. loapiUata except those of 31. subandina Spruce, which has been reduced by Evans to a synonym of 31. papillata. 31. subandina Spruce is similar in size, but the lobes are more erect, not widely spreading, and in some forms f astigiate ; in a cross- section they are 10 to 15 cells thick at the middle, which gradually become thinner in the lamina. In the examination of 31. subandina I noticed a singular feature. Many of the cross-sections showed, on the ventral side, the bulging out of a semicircular band of 5 cells X 5. This feature disappears on the younger fronds. In 31. Setchellii the fronds are 20 to 25 cells thick at the middle and abruptly become thinner winged. 1923] Pearson: Notes on a Collection of New Zealand Hepaticae 309 In M. suhandina the appendages are usually smaller, ovate acute, not longly acuminate, with only a few teeth (2 or 3), not 10 to 12, which are large and often hamate. The median scales to which the appendages are attached in 31. suhandina and in all other species I can remember examining have an entire margin; in M. SetchelUi they are distantly and shortly dentate. In all the exhaustive particulars given by Evans of Marchantia, 1 have not seen such a character noted. No description of cupules of 31. suhandina is given by Dr. Spruce (Hep. Am. et An., p. 561, 1884) for the simple reason, I suppose, that he could find none. I have examined a considerable number of fronds in the specimens distributed by him, with the same result. No species from New Zealand is listed by Stephani in his Sp. Hep. to which I can refer 31. Setchellii. 31. Berteroana L. & L. is recorded bv Evans from New Zealand, "W. A. Setchell, North Island, 1904, no. 32"; I have not received this packet from Setchell.

Observations. — This is the thinnest and most remarkable species of Riccardia I have seen, and none like it is recorded by Stephani in his Sp. Hep. ; repeated cross-sections of the frond never show more than a layer of 2 colls, with the branches and young fronds uni- stratose. That this may be an aquatic form of some other species is possible, but there are numerous imperfect female involucres on the fronds which indicate a certain maturity. Riccardia riccioides sp. nov.

Observations. — I have had the opportunity of comparing Setchell 's specimens with various ones of S. obovata from Tasmania and New South AVales, from which they differ in several particulars, and they do not quite agree with Stephani 's description of S. obovata. The plants are brown to brownish green, with no trace of rose, more rigid, fronds ligulate, not narrowty oval, cortical cells of costa larger than inner (in **>. obovata they are of equal size) ; marginal teeth erect, not projecting, 3 to 6 colls long, not 2, calyptra very small, 2.75 mm. long, not 10 mm. as Stephani says of S. obovata. My meas- urements of S. obovata are 5 to 7 mm. long ; both the $ and ^ bracts are more laciniate, the J* bracts more distant on the fronds, not crowded near the apex. 1923] Pearson: Notes on a Collection of Neiv Zealand Hepaticae 313 I have seen no specimens of S. olovata from New Zealand. Stephani says he has seen no fertile ones from that country, where the species is evidently rare. I have specimens of 8. grandibracteata St., ex herb. Levier, Nova Zelandia, AVaimata bush (Canterbury), May, 1901, legit T. W. N. Beckett, det. F. Stephani n. 2797, which although Stephani places it in another section {A. Frocumbentes) is very similar to 8. ohovata; there are no calyptras on the specimen and the $ bracts are similar to and no larger than those I find on other specimens of 8. ohovata. Stephani describes 8. grandibracteata as brownish-olive, Beckett's specimens are as green or greener than 8. obovata, with costa abruptly changing to wings, and Beckett's specimen on cross-section shows a gradual transition as in 8. obovata, 3-3-2-2-2-1. 8. puIcJira Tayl. is reduced to a synonym of 8. obovata by Stephani. This I agree with, after examination of original specimens in the Manchester Museum, collected by Drummond at Swan River. Stephani points out (Sp. Hep., Mem. Herb. Boissier, no. 11, p. 43) that Mitten is wrong in referring the New Zealand plant to 8. rhizo- loba Schwaegr., a species which is distinguished at once from all allied forms by the distinctly thickened marginal cells. Specimens named ^S'. obovata ? Basket Island leg. Spezziganni, ex. herb. Massalongo, "in the Manchester Museum agree with 8. obovata. Solenostoma brevissimum sp. nov. Plate 88 Dioicous.

Calif., no. 213710. Observations. — The Solenostoma humile Mitten, Royal Soc. 1879 listed by Stephani in Sp. Hop. (Bull, de I'Herb. Boissier, ser. 2, as of p. 50, 1906) is a myth. From Nardia humilis Berggren, N. Zeal. Hep., p. 7, it differs in its oval leaves, not orbicular, trigones wanting or very small, not large, narrowlj' oval perianth not ovate. The figure of the perianth represents a mature one ; when young the mouth is small and shortly tubular with a few minute setae. I refer my species to Solenostoma Mitten on account of this character along with the perianth's being adnate to the bracts, but I consider that there are species included in the genus by Mitten and Stephani which ought to be placed elsewhere. Jung, inundata Tayl., a species with large underleaves, as Stephani correctly states, although Mitten in Handbook Fl. N. Z., saj^s "without," is one, for instance.

Observations. — I have read somewhere, but I cannot remember where, that when a complimentary name is given to a plant, there should be no doubt as to its specific value ; consequently I have given more time to the study of this plant than to any other in the collec- tion, in order to satisfy myself as to its position, being anxious that it should stand good. 316 University of California Puhlications in Botany ["^'ol. 10 iStephaui, after his description of Plagiochila deltoidea Lindenb. in his Sp. Hep. (Bull, de I'Herb. Boissier, ser. 2, vol. 4, no. 8, p. 783, 11)04), says: "This phmt probably does not occur in New Zealand and has been confused with Plagiochila Howeana St." Lindenberg, the founder of P. deltoidea, gives Dusky Bay, New Zealand, as the first station for it, then Tasmania. The Barbados record maj' safely be deleted. Although no indication is given, I think we may assume that the figures of P. deltoidea given on plate XXVII by Lindenberg in his Spec. Hep. are taken from New Zealand specimens, for in his notes on the species, he remarks that the Tasmanian form has "minuteh^ denticulate leaves," probably constituting quite a distinct species from our more modern standpoint. These figures undoubtedly represent Stephani's P. Howeana, much more accurately than the P. deltoidea from Tasmania and other countries. A careful re-examination of all my specimens named P. deltoidea disclosed several inaccuracies. I have one from New Zealand determined by Stephani which is P. Banksiana, and several others named by him from New Zealand are his P. Howeana. Gepp of the British Museum informs me that in a set of Exotic Hepaticae received from Stephani there are 4 specimens from New Zealand named P. deltoidea and none P. Howeana. There is no doubt in my mind that Stephani is right in distin- guishing the New Zealand forms from those from Tasmania and elsewhere ; the darker green color, the shorter, more quadrate outline of the leaves, the more recurved antical margin of the leaves, the smaller cells, are distinctive, but Stephani does not make this clear in his descriptions. The narrow elongate ligneous-walled basal cells give the leaves at their base a broad vittate appearance, while in P. deltoidea they are large and roundish-quadrate with large trigones, very similar to the other cells. These characters enable a student to separate them readily, and although the proposal I am about to make may seem somewhat unusual, I make P. Howeana Stephani a synonym of P. deltoidea Lindenb. and propose for the Tasmanian and other similar forms the name of P. neohowcana Pearson, so as to retain the name of my valued friend, Dr. Marshall A. Howe, of whom Stephani says, "the plant bears the name of the distinguished North American botanist (the investigator of the California Hepatic Flora)." 1923] Pearson : Notes on a Collection of New Zealand Hepaticae 317 Plagiochila gigantea (Hook.)

I find that to be the case with all specimens I have examined from New Zealand and Tasmania. fSande la Coste in his description of his Lophocolca horridula says of the leaves, "dorsum papillis elevatis conicus, in ventre deficienti- bus. " This is a species which has been referred to L. muricata by Stephani. Lophocolea muricata according to Stephani has a very wide dis- tribution.

The specimen is too meager to determine with certainty, but may be referred to C. hirta St. until better specimens are obtained. It differs, however, from C. hirta in being only half its size, stems 3 to 4 mm. long, not 8 ; also the cuticle is papillose, of which no men- tion is made by Stephani, although specimens recorded from Queens- land, by him, collected by C. J. Wild, have the same character. Stephani does not report his C. hirta from New Zealand, although Colenso and Rodway record C. dentata from there, which according to Stephani 's synonymy is the same as his C. hirta. The plant is very minute, .stems simple or once branched, branches postical, rhizoids few, delicate, ascending to apex of the stem; leaves distant, alternate, bifid to the middle, segments and sinus acute, denticulate, cuticle papillose. 1923] Pearson: Notes on a Collection of New Zealand Hepaticae 319 Lembidium nutans (Taylor) Mitten Mitten, Handb.

Mitten in Hooker's Handbook of the New Zealand Flora, savs of Lemhidium nutans, "the stem is clothed with a vesicular coat." Spruce in a footnote adds, "Mitten attributes 'a loosely cellular coat' to the stem. There is, however, none such and the 'looseness' exists solely in the author's perceptions." I know there was no love lost between these two authorities but I think this is the only instance where their loss of love is shown. In Lindenberg & Gottsche 's Spec. Hep,, t. 22, is given a cross- section of a stem with an underleaf attached, which shows the stem to be thicker than it is broad. It is not so : it is broader than it is thick. I find that the cortical cells are about the same size as the inner, but there is one peculiarity about the stem. At each lateral side, the central cell is usualty larger and prominent, so that when the stem is observed lying flat it appears to have a loose cellular coat — a justi- fication for Mitten's apparent looseness of observation.

Nova ZeaUmdia St., from the description, but specimens of the latter which I have seen, collected by J. Meckle- john near Lake Wakatipu, Ncav Zealand, and determined by Stephani, indicate that it is a smaller and more delicate plant, irregularly ramose, having leaves with larger cells, and underleaves much more deeply divided. L. hrevipinna is recognized at once by its graceful, regular shape, given to it by its short pinnae. Isotachis Lyallii Mitten Mitten in Fl. N. Z., II, p. 149, t. 100, f. 7.

Observations. — The reducing of L. Taylori (Gottsche) to a variety of L. clavigera (Hook.) by Mitten (Handb. Fl. N. Z., p. 529) may possibly account for the uncertainty which several collectors have shown as 1o L. Taylori, to judge by the various specimens I have received under wrong names. Mitten simply says (when making it a variety) : ''var. Taylori Cauline leaves toothed and spinose on the ventral margin," but Gottsche, the founder of the species, saw more differences. The underleaves, to mention another character, are quite different. They are deeply quadrifid, with the segments spreading and irregularly laciniate-spinulose. In L. clavigera they are not so deeply divided and are entire, slightly calcarate at the base. Lepidolaena papebrifolia (Gottsche) has underleaves much nearer to L. Taylori than has L. clavigera, but the segments are still more spinulose and ciliate than L. Taylori and can be at once dis- tinguished from that species by the absence of laciniae on the antical base of the leaves. The var. Stangeri G. to which Setchell 's specimens belong, differs from type by having its branch-leaves sometimes dentate-serrate. Schistochila nobilis (Hook.) Dum. Eec, p. 15, 1835.

In addi- tion to the perianth being plicate, a unique character in this genus so far as I know, the leaves on their antical (upper) margin are abruptly and acutely truncate, Stephani remarks under R. plicata (Sp. Hep., vol. IV, p. 214, 1910) "that the folding of the perianth is usually not noticeable, and only in the old branches to be observed, evidently an indication of their coming decay. ' ' This is not so, for in the numerous perianths on Setchell 's specimens they are of different stages of growth and the plication is always to be seen ; in fact the ridges are really narrow wings, 1, 2 and 3 cells wide. Its nearest ally is B. physoloba Mont., a species which Stephani does not think belongs to the New Zealand flora. The specimens he received from there, collected by Beckett, are so poor that the ques- tion is undecided. There are specimens (3074) in the Manchester Museum named B. physoloba Mont. (I do not know by whom), collected by Sinclair in New Zealand, which are B. plicata, but they are without perianths. Also, there is a specimen named B. physoloba (Jung, flavifolia Tayl.) from Cape Horn (20569) which represents a distinct species as recog- nized by Taylor, Jour, of Bot., p. 476, 1844, the acute leaves at once distinguishing it. Through the kindness of Professor Dismier I have had the opportunity of examining the original specimen of B. physoloba of Montague. It is a different species from that collected by Weymouth in Tasmania and determined by Rodway, the lobes of the leaves being rounder, with the lobules having an acute angle. The Badvla plicata listed by Rodway in his Hepaticae of Tas- mania, with the mouth of the perianth fimbriate, must belong to another species. T have the pleasure of being able to add drawings from the orig- inal specimens of Badula physoloba ]\Iont. and Badula flavifolia (Tayl.), (cf. plates 97 and 98). 1923] Pearson: Notes on a Collection of New Zealand Hepaticae 325 Madotheca Stangeri G.

The species here named by him after Colenso is remark- able in having the large appendix of the leaf triangular and acute in shape. This can be well seen only by detaching a leaf from the stem and flattening it out with the cover glass. It is a remarkable character and I have not seen it in any other species. Stephani in his description of the species says he had not seen the male plant. On Setchell 's specimens there are several male stems. Frullania (Galeiloba) fugax Tayl.

Observations. — Although the plant was collected in considerable quantity I have not been able to find any trace of J* or 5, so am not able to say to ^Yhich sub-genus of Anthoceros the species belongs. Mitten records only 4 species of Anthoceros from New Zealand, all very different from the above, and Stephani records 6 Megaceros and 3 Anthoceros, to none of which does this species agree according to his descriptions. 328 University of California Publications in Botany [Vol. 10 The plant has very much the appearance of an Aneura, to which genus I thought it belonged, but Lang, to whom I submitted specimens at once put me on the right track with some interesting information as to the Nostoc colonies. In the collection I have been able to pick out only a few stems of two Lejeuneae, one probably Eulejeunea and the other Micro- lejeunea, neither of which I am able to refer to any described New Zealand species, but they are too few to publish safely as new.

Observations. — The only Pallavicinia from New Zealand with which to compare P. Sctchellii is P. connivens (Colenso) St., which has, according to Stephani's description (Proc. Linn. Soc, p. 270, 1893), reniform or sub-circular fronds, which are repeatedly furcate, texture fleshy, marginal teeth straight, archegonia 6 to 8, with cells 0.025 mm. (Sp. Hep., p. 324, 1900). P. Setchellii has usually linear, more rarely sub-orbicular fronds, with firm texture, marginal teeth hamate, archegonia 30. Sterile forms of Pallavicinia may be mistaken for Symphyogyna, which genus has also an antical inflorescence, but as Stephani remarks (Proc. Linn Soc, p. 271, 1893), "The cylindrical involucre distinguishes Pallavicinia at once from Symphyogyna, the pistils of which are merely covered by a scale free at the sides and inserted on the frond by its base alone, so that it can be turned back- wards without a rupture." I add a figure of bract of Symphyogyna grandibracieata St., a specimen of which I took occasion to compare with my plant. Through the kindness of the Director of Kew, I have been able to see the original specimens of Pallavicinia connivens (Col.) St. The plant is much smaller, with a long stipe, which abruptly dilates into a radiate frond, margin with a few coarse teeth which might almost be called segments. Habitat.— Tauipo, Mav 16, 1904.

Some forms seem so different from the type that one feels inclined to consider them as distinct, but the characters vary so much in the same tufts and even on the same plant that I have solved the difficulty by lumping them together. Observations, No. 46. — This is a small male form with leaves entire, retuse or emarginate, and with underleaves free, bifid with exterior tooth on both sides. Observations, No. 42. — The specimen represents a small, flaccid innovant form, with numerous involucres but no perianths. The involucres are compressed and that, along with the comparatively large patulous underleaves, gives it the appearance of a Leioscyphus. I add the notes I made on its examination. Stem 1 cm. long, simple or rarely with a small branch, repeatedly innovant, 3 times; on a cross-section, stem broader than thick, some- what angular, 15 cells by 10, cortical cells 30, similar to the inner ; leaves broadly ovate, obtuse, rotundate, retuse or on the young branches bifid ; cells small to smallish, quadrate, 4, 5 and 6-sided, walls thick, trigones very small ; underleaves roundish-quadrate, bifid to about the middle, long tooth on exterior side of segments, segments acuminate, narrowly connate with one or both leaves, patulous, stand- ing off from the stem ; sub-bracts entire, often with a minute tooth at their base ; bracts broadly ovate, entire, apex obtuse or rotundate ; bracteole quinquedentate ; perianth (young) with mouth laciniate; archegonia 20 ; perigonial bracts oval, ventricose.

Observations. — For a time I was inclined to look upon this form as a distinct species, but, after repeated examination and comparison with all my other specimens of L. heterophylloides, I refer it as a variety under this species. The large, 6 and 7-toothed underleaves, the 1 or 2 minute teeth on the upper leaves and sub-bracts at their base, the large, firm perianths 3 to 4 cells thick near the base, seem to justify its separation, but the findings of young bifid leaves and the approach to its other characters in other specimens of L. heterophyl- loides induce me to consider it as only a variety of this variable species.

T have seen the original specimens of both and with neither of them does F. lacinaeflora agree. F. pycantha Tayl. is a much more robust species, stems 4 to 5 cm. long, reddish brown in color, 1923] Pearson: 3Iorc New Zealand Hepaticae 379 branches narrowly pinnate, leaves very sq^^arrose, underleaves longer than broad. Stephani, in his description, Sp. Hep., says: "appendix subligulate, rotundate, connivent, lobule with large beak, underleaves small, only a little broader than the stem, broadly obcuneate, lobes apiculate; perianth obovate; bracts, lobe obovate-acute, lobule interior margin coarsely lacerate, bracteole coarsely spinose. " F. rostellata Mitten, of which the original specimen was kindly loaned to me by the Director of the Royal Botanical Gardens at Kew, has leaves concave, not squarrose ; horizontally inserted, not vaginate, larger cells with large trigones, ovate-oblong (1 mm. X -65 mm) ; lobule very large, longly decurved, hooked with a long beak ; and has underleaves with dentate margins; perianth obovate-oblong, laciniae much larger and longer, 6 cells long, with beak very long. In F. Jacinaefiora, the minute lacinae with which the perianth is clothed are unique, so far as observation goes. They are very minute and numerous. I counted more than a hundred on the antical side which are 3 cells long and 3 cells wide at their base, all pointing upwards. The spores are also very singular, being regularly and beautifulh^ tuberculate and having on their face 15 to 20 little circular dots, which are more evident on the younger spores.

Observations. — The only Frullania belonging to the Galeiloba section which has exappendiculate leaves is F. decurvifolia St., and 380 University of California Publications in Botany [Vol. 10 this differs from F. ohtusiloha in having lobules as broad as high (.27 mm.), not broader than high (.2 mm. X .125 mm.) ; underleaves three times broader than the stem, not twice, obeuneate not orbicular ; margin dentate on both sides, not entire ; with segments subacute, not obtuse or rotundate. It is somewhat of a risk to found a new species on sterile Frullania plants, but the remarkable obtuse or rotundate segments of the underleaves enable the plant to be distinguished readily from any other.

Calif. Pub. Bot., vol. 6, no. 1, pp. 1-34), pi. 1-6) I published what was intended to be the first of several papers on the floridean parasites, especially on floridean hosts. The publication of other species than those of Janczewskia has been delayed by pressure from other projects. In 1918 (Proc. Am. Philos. Soc, vol. 57, pp. 155-172), I reviewed the progress made in our knowledge of the parasitism of the Red Algae and (pp. 165, 166) referred to certain unnamed species in my possession, but as yet unpublished. It seems best, therefore, to publish the diagnosis of several new genera and species, awaiting the completion of the work of more thorough illustration and the drawing up of more complete descrip- tions?, which are, however, in advanced preparation. Gracilariophila Gardner! sp. nov.

Parasitic on Gracilaria Cvnninghamii J. Ag., near Santa Monica, California, January, 1913, N. L. Gardner, No. 2576. Gracilariophila seems to be quite distinct from HarveyeUa (cf. how- ever, Eddelbiittel. Bot. Zeit., vol. 60, p. 230, 1910) and G. Gardneri is a larger species than G. orfizoides Setch. and AVilson. with cystocarps projecting more conspicuously. 394 University of California Piihlications in Botany [Vol. lo Faucheocolax gen. nov.

Parasitic on the stout basal portions of Nitophyllum Ruprecht- ianum J. Ag.. at Lands Fiud, San Francisco, California, December, 1905, W. A. Setchell, No. 6227. This is a plant frequently found in rosettes at the base of the "stipe" of Nitophyllum Ruprechtianum J. Ag. all along the Pacific coa-st of North America. I have quoted only the type specimen since 1923] SetcheU: Parasitic Florideae, II 395 more careful study of materials from other localities must be made. Unfortunately I have no material for careful comparison with G. Buffhami Batters. The polyspores are possiblj^ a sufficient character- istic upon which to found a new genus. There are certain peculiarities of vegetative structure, also, tending away from Gonmiophyllum. Polycoryne Gardner! sp. nov.

Parasitic on NitophyUnm Andersonianum J. Ag., Point Cavallo, Marin County, California, October, 1913, N. L. Gardner, No. 2594. This species, the second to be referred to the genus Polycoryne, is readily to be distinguished from P. radiata Skottsberg by the basal position of the cystocarp and the proportionally longer acute tip of the cystocarpic branch! et. P. radiata was detected at Maihafen in South Georgia Island in the Antarctic Ocean, para-sitic on a species of Nitrophyllum, probably N. polydactyhim. StromatocarpiTS Gardneri sp. nov.

A REVISION OF THE WEST NORTH AMERICAN SPECIES OF CALLOPHYLLIS BY WILLIAM ALBERT SETCHELL A EEA^ISION OF THE WEST NORTH AMERICAN SPECIES OF CALLOPHYLLIS BY WILLIAM ALBERT SETCHELL The North American species of CallophyUis have never been revised, or even critically studied. Some years ago Dr. Olive Swezy, at the advice of the writer, made a critical study of our West Coast forms and the writer himself has since extended these observations. The greater number of the species referred to, or possibly referrable to, this genus have been examined and the following arrangement has been adopted. This account is preliminary to a full discussion at some later date. Key to the Species of Callophyllis of the Pacific Coast op North America 1. Cystocarps on terminal segments only 2 1.

MEERILL During the past two or three years Dr. A. Petelot of the Entomo- logical Station at Cho-Ganh, Indo-China, has submitted, to me from time to time, for identification, an extensive series of botanical speci- mens. Among these a considerable number of species are represented that are apparently undescribed. The present paper contains the descriptions of thirteen forms which I consider to represent new species, with notes on several previously described forms that are of sufficient general interest to warrant brief discussion. The types of the new species herein described are preserved in the Herbarium of the University of California. GRAMINEAE Eremochloa Petelotii Merr. sp. nov.
