REPORT OF THE SECRETARY AND DIRECTOR- IN-CHIEF FOR THE YEAR 1907 (Accepted and ordered printed January 13, 1908) To THE Boarp oF MANAGERS OF THE NEw York BoTan- ICAL GARDEN. Gentlemen: 1 have the honor to submit herewith my report as Secretary and Director-in-Chief for the year ending Jan- uary 13, 1908: Progress in the development of all departments of the Gar- den has been made during the year. A large amount of additional construction work has been accomplished by means of an appropriation for that purpose made by the city in the spring. The collections have been considerably increased, mainly by gifts, and by the plants and specimens obtained by explorations in tropical America, aided by gifts of money by members of the Board of Managers and other friends of the Garden. The labeling of collections has been brought to a very efficient stage and the educational work of the in- stitution has been expanded. The number of visitors con- tinues to increase. The permanent funds of the Garden have received only slight additions by life membership fees, stu- dents’ fees, and contributions to the Endowment Fund, aggre- gating about one thousand dollars. The value of gifts of living plants, specimens and books aggregates $11,063.90 ; these gifts have been recorded in the monthly JouRNAL. The general maintenance of the Garden has been accomplished by the city appropriation of $75,000, supplemented by part (1) (2) of a special appropriation of $13,000 made by the Board of Managers for this purpose. The necessity for making this appropriation seriously diminished ‘our ability for purchasing desirable plants, specimens and collections. he total membership of the Garden is now 1,167. Construction of Roads and Paths The river road extending from the east end of the Long Bridge northwardly along the east side of the Bronx River to the Newell Avenue entrance, on which work has been prosecuted at intervals for several years, was completed and thrown open for use in November, completing the driveway system in the northeastern part of the grounds; this road has a total length of a little over 2,000 feet and forms a note- worthy addition to the driveway system. The main driveway at the Lake Bridge, which has been unfinished since the completion of that structure two years ago, was paved and surfaced during the autumn, thus com- pleting the main north and south driveway through the west- ern part of the grounds. The road leading from the main driveway near the Bleecker Street entrance on the east side of the grounds to the new public conservatories now under construction, was graded and nearly all the telford foundation laid during the year; its completion requires broken trap rock and screenings. A beginning was made in grading the portion of the main driveway still to be constructed from a point near the Bleecker Street entrance to the southeastern corner of the grounds, in accordance with the original plan, and stone for the telford foundation of a part of this road is being assembled dur- ing the winter, taken from the quarry behind the museum building. This is now the only remaining portion of the driveway system to be built, a total length of 1,800 feet. The construction of the path system has been continued at a number of different points and much progress has been made. The paths about the lakes north and east of the mu- seum building, and those on the fruticetum plain, partially (3) built in preceding years, werecompleted. The paths leading from the museum building and the herbaceous grounds through the economic garden and adjoining areas were com- pletely built; the path leading from the herbaceous garden southward through the woods to the Bronx Park entrance, partially constructed in preceding years, was also com- pleted. A commencement was made in the construction of paths leading from the Long Bridge eastwardly toward the new public conservatories, and in those leading from the fruti- cetum, northwardly through the north meadows to the upper driveway bridge. The total length of paths built and completed during the year is about 9,000 feet. Through the codperation of the Department of Parks all the previously constructed driveways and paths that needed resurfacing were covered with a thin layer of trap rock screenings during the autumn and thoroughly rolled, the entire driveway and path system, so far as constructed, being now in excellent condition, except at a very few points where slight repairs and small amounts of additional construction are necessary. It is very desirable that the work of path building be con- tinued during the next year in the eastern part of the grounds in order to connect the new public conservatories with the bridges over the Bronx River. Bridges The bridge for pedestrians, built of rounded boulders, taken mainly from old stone walls, replacing the old wooden ‘¢ Blue Bridge” at the northern end of the Hemlock Forest, on which preliminary work was accomplished late in 1906 under the contract of the Park Department with Mr. M. J. Leahy, was completed in September. This construction performed the double work of providing a unique permanent bridge and of clearing the grounds of boulders. The path approach to its western end had been previously built, and a temporary path approach to its eastern end has been made. (4) The three driveway bridges built in previous years have required no repairs. The concrete and cement sidewalks of the Lake Bridge were built in September. The permanent sidewalks for the Long Bridge and for the Upper Bridge still remain to be constructed. During the year considerable study was given to plans for the bridge proposed by the Commissioner of Parks to replace the wooden foot bridge south of the waterfall near the Loril- lard Mansion, for which an appropriation had been voted by the Board of Estimate and Apportionment to the Park Depart- ment. The western end of this bridge will stand on land within the Garden reservation, its eastern end on land of the Park Department. The plans for this structure have not yet been brought to completion. It is very desirable that this bridge should be built, inasmuch as the present wooden bridge below the waterfall is much too narrow for the accommoda- tion of crowds of visitors and it is approached only by steep descents at either end. Grading Continued progress has been made during the year in excavating earth and rock at the rear of the museum building, all the excavated material having been used for filling at various parts of the grounds or for the telford foundation of driveways and paths, and the work is progressing during the winter. Much still remains to be done at this point in order to establish the grades called for in the general plan, but inasmuch as all the earth and rock are needed for filling or for road and path building, double work is continuously being accomplished. It is estimated that enough rock and earth to nearly or quite complete the road and path system remains. It will be possible in the spring to bring nearly an acre of the area behind the museum building to finished lawn. The filling and grading required at both ends of the Lake Bridge and at both ends of the Long Bridge was completed during the season. Considerable progress has been made in filling low places in the north meadows while building paths in that part of the grounds. (5) Much additional grading was done along the river road and along the road leading to the new public conservatories. In the herbaceous grounds the sides of the brook which runs north and south through the middle of the valley were regraded and the brook edges stoned up, greatly improving the valley. The topsoil needed for these grading operations has all been obtained by carefully stripping and saving it from the lines of paths and roads. Drainage Accompanying the construction of roads and paths, addi- tional catch-basins with drain-pipe connections have been constructed, and the system of grass gutters along the drive- ways has been continued. The overflow from the bronze fountain in front of the museum building, which was tempo- rarily discharged into one of the sewers and thus wasted, was turned into the drain system which empties into the upper lake, by means of a drain-pipe connection about 400 feet long under the lawn south of the museum building ; this waste water has kept the upper lake at overflow throughout the season, although the fountain has been played only about ten hours a day. During grading work in the herbaceous garden and in the establishment of the aquatic system in the economic garden, several hundred feet of tile drain were used, much improving the drainage of that valley. At the power-house of the new conservatories a 12-inch vitrified tile drain was laid for a distance of about 150 feet, passing under the floor of that building; as the construction work proceeds at this point much additional drain-pipe will have to be laid, inasmuch as the excavations for the cellars both of the power-house and of three of the greenhouses have shown the existence of springs. In my last annual report I referred to the desirability of lowering the dam in the Bronx river at the Lorillard mansion an additional 8 inches, 16 inches having been taken from it in the summer of 1902. This has not been done, owing to (6) the pressure of more important work, but it is still desirable, in order to improve the drainage of the north meadows. Water Supply The 6-inch main along the north and south driveway east of the Bronx river was tapped at a point north of the lake bridge, about 1,500 feet of 6-inch water-main laid from that point along the south side of the east and west driveway, ex- tending to the plaza near the Bleecker street entrance; from this point a 4-inch water-main was laid along the east side of the driveway approach to the new public conservatories, a distance of about goo feet, thus furnishing water supply at these buildings. A rI-inch galvanized iron water-pipe was laid from near the New York Central Railroad station, a dis- tance of about 500 feet parallel with the railway to the Mosholu parkway approach, in order to supply facilities for watering the steep driveway at this point, which proved in- convenient for the watering-carts. About 400 feet of 1-inch pipe was laid in the Economic Garden. It is very desirable that the water-supply system should be extended as rapidly as possible, in accordance with the gen- eral plan. About one-half of the 6-inch and 4-inch main planned for the grounds has been laid from time to time along the driveways and paths, so that a good beginning has been made. The driveways have been kept watered by the Park Department whenever watering-carts could be spared from the parkways and other parks, but the service has not been sufficient owing to the very large extent of driveway to be cared for in the park system of the Bronx. The method of watering Telford-Macadam roads by watering-carts is not an economical one, because it requires a large number of men and horses which are not continuously occupied; very often in rainy weather during the summer the roads require no water for several days at a time, and again in dry weather they require almost continuous sprinkling in order to keep the surface in good order. In the original plan for the water-supply system as de- (7) scribed in the report of the Plans Commission of the Garden * it was recommended: ‘All these pipes are located along the proposed roads, rather than under them ; they are so arranged that hydrants can be placed along the roadsides at intervals, so that by using hose any parts of the roads, walks and plan- tations can be reached.” After a careful study of the method by watering-carts I am convinced that this method of watering the roads and walks by hose would save much money and be far more efficient. In order to bring it into operation for the Garden grounds about 6,000 feet of 6-inch cast-iron water-pipe and 3,000 feet of water-pipe of smaller diameters, together with hose- taps at intervals of about 150 feet, are required. Buildings A contract for the construction of the boiler house and the subway connecting this house with the new public conser- vatories was awarded early in the year by the Park Depart- ment to the firm of Kelly and Kelley and work was begun in the spring. These structures are now nearly completed, the cost being $25,600. Another contract awarded by the Park Department to the same firm during the summer provides for the construction of five of the glass houses, costing $62,796; during the autumn the excavations for cellars for these buildings were made and the foundation walls partly constructed. Both these contracts will presumably be completed by midsummer so that the five new greenhouses will be ready for use at that time; they will supply a much needed relief to the crowded condition of the first range of public conservatories, and as soon as they are completed the necessary grading in the vicinity can be taken up. As already stated, the driveway and path approaches to these buildings have been partially built, and a water-main laid for their supply. Accounts of the maintenance and repairs of buildings will be found in the report of the First Assistant and in that of the Superintendent of Grounds, hereto appended. ~ *Bull. N. ¥. Bot, Gard. 1 :" 43. (8) Boundary Fences In the autumn a contract was awarded by the Commis- sioner of Parks to Guidone and Galardi for the construction of a boundary wall and fence along the property line of Fordham University, extending from the Elevated Railway Station on the west to the Southern Boulevard entrance on the east, a distance of about 2,000 feet, the contract price being $17,000. Surveys for the location of this fence were carefully made by the Park Department and construction work may be commenced in the spring. The design of this wall and fence was duly approved by the Board of Managers, after slight modification by the Commissioner of Parks for the Borough of the Bronx. It is desirable that other portions of the boundary of the garden be permanently fenced, the line along the right-of-way of the New York Central and Hudson River Railroad Company being the next most im- portant to be secured. It will probably be unnecessary to fence the eastern and northern boundaries for several years. Telephone Service. The museum building, the first range of public conserva- tories, and the power house at the Bedford Park Avenue entrance, are connected by telephone cables through the sub- ways containing the steam-pipes, the cables having been put in during the construction of these subways. The mu- seum building is connected with the stable and with the propagating houses by an underground cable laid along the paths crossing the river at the Boulder Bridge. Previous to the construction of this bridge the wire passed under the river, but upon the completion of the Boulder Bridge it has been carried over that structure. The construction of the new public conservatories and power house required an elab- oration of the telephone service and this was supplied during the summer by laying an 8-wire lead-covered cable under- ground from the museum building, crossing the Lake Bridge and the Long Bridge, to a point at the plaza near the Bleecker Street entrance; from this point a 4-wire lead-covered cable (9) was laid underground along the driveway approach to the new conservatory ; these cables were mostly laid in the water- main trenches before closing them; to complete the system it is still necessary to connect the stable and propagating houses with the end of the 8-wire cable in this plaza, and dispense with a portion of the wire previously laid. We shall thus have all buildings connected by underground cables. The museum building has long been connected by underground cable with the public telephone system of the city. The Telephone Company has recommended to me that a public telephone booth be provided in the museum building and I regard this as desirable ; I recommend that the Garden’s tele- phone system be brought to such a central booth when com- pletely established and that all telephonic service be put in charge of an aid who will also be assigned the sale of guide books and photographs. Plants and Planting Planting was carried on at various parts of the grounds during the spring and fall, taking advantage of the large amount of additional land prepared for it during the past two years, as recorded in detail by the Head Gardener in his report hereto appended. This work included the completion of the west border along the New York Central and Hudson River Railroad, which was broken by the construction of the approaches to the Mosholu Parkway and to the Woodlawn Road, and the filling in of the gap near the west end of the upper lake; the completion of the planting of the economic garden in the glade southeast of the museum building; the planting of flower gardens in the rectangular plots at the north side of the first range of public conservatories, and in- creasing the systematic collections in the herbaceous grounds, the fruticetum, the pinetum and the arboretum, together with the establishment of decorative groups of shrubs at several points. It is desirable during the coming year to continue planting operations in accordance with the general plan, both by (10) increasing the systematic collections and by additional plant- ing of trees and shrubs along the driveways and paths in ground already prepared. Continued attention has been given to the labeling of the systematic collections both in the conservatories and out-of-doors, about 3800 painted labels having been made during the year. This continued progress in the labeling of the collections is most satisfactory and by carrying it along at the same rate of progress during the next year, a very large proportion of the specimen plants will be provided with labels. The Hemlock Grove I have suggested in two previous annual reports that it would become necessary, in order to insure the safety of the hemlock forest, to restrict its use by visitors to certain well- defined trails or paths, inasmuch as the indiscriminate tramp- ling of the thin soil by crowds of people would in the end be dangerous to the hemlock spruces. Up to the present time no serious damage has ensued, but the increasing number of visitors in summer and the impossibility of restraining gen- eral picnicing, have made it quite apparent that the trails should be indicated and fenced; this fencing would keep the great majority of visitors within the lines of the trails. The character of this fencing has been given very careful atten- tion; it is necessary to preserve the general sylvan aspect of the forest, so that no formal fence lines are permissible, and after much consideration I now recommend that the trails be given an average width of about 12 feet and fenced on both sides by locust posts, 2% to 3 feet high above ground, sur- mounted by a single split red cedar rail, the two to be spiked together; this method of construction would supply an ordi nary fence such as might frequently be seen in woodlands, with this construction in mind a large number of dead and dying locust trees have been cut from the grounds in preced- ing years and the trunks stacked, and a large number of dead and dying red cedars have also been cut out and the trunks reserved, so that material is at hand for a consider- able portion of this necessary fencing. (x1) As recorded by Dr. Murrill, in his report as First Assistant, the chestnut trees, both within the hemlock forest and at other points within the grounds, have been decimated by the ravages of the chestnut fungus, which it has been impossible to combat; a large number of these dead trees were removed during the early part of the year and others should be cut down within the next few months. In accordance with the terms of the agreement with the Park Department relative to the hemlock grove, the cutting out of any trees within the grove has been under the observation of an official of the Park Department detailed for this duty. Museums Detailed accounts of additions to the public museums and of additional cases constructed during the year, will be found in the reports of the Head Curator of the Museum and Herbarium and of the Honorary Curator of Economic Col- lections, hereto appended. The general plan of work has been the same as in preceding years, looking toward the more complete and satisfactory illustration of the various groups of objects, by the addition of fruits, seeds, barks, woods, and other products, and of photographs and other illustrations. Continued attention has also been given to the labelling of the collections. he addition of six large floor cases in the basement of the museum hall permits the display of a large number of additional specimens of fossil plants which have been held in storage, and this installation is now in progress. A large number of photographs illustrating various phases of plant life have been accumulated which it is desirable to frame and hang on the museum walls and it is hoped that some progress may be made with this work during the year. Herbarium The development of the collection of dried specimens has been continued, the additions to this collection aggregating about 49,000 specimens, partly received in previous years (12) and partly obtained during 1907. Much time has been given by the curators to the accurate naming and classification of the herbarium, which is being more and more consulted by curators from other institutions and by students from all parts of the country. The very important collection of fungi of the herbarium was rearranged and installed in new herbarium cases in the large room at the west end of the upper floor of the museum building, which has hitherto been used for miscellaneous pur- poses, thus leaving much additional space for the collection of ferns, mosses and lichens, in the rooms east of the library. Some additional assistance in mounting and distributing speci- mens, obtained by gift, purchase, or exchange, which have accumulated in the storerooms, is very desirable during the coming year, in order that this material may be made avail- able for students and investigators. Library The use of the library by students and visitors is increasing as the collection becomes more complete. 592 volumes were added during the year, obtained by purchase and by gift, the total number of volumes being now 20,458, as appears in the report of the librarian, hereto appended. The endeavor to secure the older literature of botany, systematically com- menced two years ago, has been continued, and many im- portant works now difficult to obtain have been added. As pointed out in previous reports, this literature is continually becoming scarcer, owing to the largely increased number of libraries throughout the world, and it is therefore highly im- portant that the effort should be continued, and funds are de- sired for this purpose. During the year a contribution of $100, from Mr. E. S. Harkness, was credited to the Special Book Fund. The position of librarian, held by Miss Anna Murray Vail since 1899, became vacant in October by her resignation, which was received with much regret. Dr. John Hendley Barnhart was appointed librarian at that time. (13) Space for the additional books secured during the year was obtained by adding new shelves to the steel cases already con- structed, no additional cases having been required. The number of institutions now on our exchange list for publica- tions of the Garden is about 600, as against 57o recorded in my last annual report. The monetary value of the publi- cations which we annually receive in exchange is about $850. Laboratories The laboratories have been used by many students pursu- ing special investigations during the year, as detailed in the report of the Director of the Laboratories, hereto appended. No considerable changes have been made in the equipment, though some rearrangements of furniture and fixings have been found desirable. In my last annual report I recorded an inquiry made of a number of universities, gardens and museums, relative to pro- posed codperation in developing the tropical laboratory of the Garden at Cinchona, Jamaica, looking toward the possible establishment of a resident investigator at that station. It was proposed by representatives of some institutions that this be accomplished by the contribution of $100 a year by fifteen or twenty universities, museums or gardens. I have to report that this movement was not successful, only five institutions finding themselves able to join in the proposed work, although the movement was most cordially approved. The buildings at Cinchona were somewhat seriously damaged by the earth- quake which devastated the city of Kingston last January, but they have been put in complete repair by the Jamaica Government without expense to the Garden, and students may now be received there as formerly. There is no doubt that this station provides exceptional facilities for investigations of tropical and subtropical plants, and that important additions to knowledge would be made by the residence there of a trained investigator. (74) Lectures and Demonstrations The public lectures delivered at the museum building on Saturday afternoons during spring and autumn have been continued to appreciative audiences. The time for the lecture was changed from 4 :30 to 4 o’clock. Consideration has been given to the desirability of extending these lectures into the summer months, but this has not been attempted as yet. It does not seem probable that audiences could be assembled for such lectures during the winter, but a course of summer lectures might prove desirable. e lectures and demonstrations to children and teachers of the public school in codperation with their nature studies, were continued during the spring from April 19 to June 4, in codperation with the principals and district superintendents of the Borough of the Bronx, and of the upper school districts of Manhattan. The attendance of children and students was quite as large as during the preceding course. In order to give more official recognition of this codperation, the school principals of the Bronx have recommended that the arrange- ments for selecting and sending children to the Garden be taken up directly by the Board of Education, and, pending a decision on this question, no lectures nor demonstrations were arranged during the autumn. The matter was referred by the Board of Education to the Board of District Superin- tendents and it is hoped that this important work may be further elaborated during the coming spring. Details of lectures and demonstrations and of meetings held at the Garden during the year will be found in the report of the First Assistant, hereto appended. Guides and Guide—Books The arrangements for the personal guidance of visitors through the grounds and buildings made last year were con- tinued and have been much appreciated by those who have taken advantage of them. The total number of persons es- corted in this way has not been very large, but it is no doubt desirable to continue this work. (15) The guide-book, issued late last year, was placed on sale at the museum building and at the approach to the elevated railway station, together with selected photographs of special features, other publications of the Garden, and specially pre- pared postal cards. Exploration By means of a small appropriation from general funds and of special contributions for the purpose, botanical exploration and collecting has been prosecuted in the West Indies to the great advantage of the collections of living plants and of the museums and herbarium. Contributions credited to the special exploration fund were received as follows: D. O. Mills $1,500 Field Museum of Natural History, advance on account of Exploration of the Bahamas...... 250 Morris K. Jesup 100 S. S. Palmer 100 Samuel Sloan 100 . Van Beuren 50 Bradley Martin 50 O. H.

Howe, a Museum Curator, spent parts of December, 1906, and January, 1907, on the island of Jamaica making collections and field studies of marine algae, in con- tinuation of his previous investigations of these plants. The continuation of the exploration of the Bahama Islands was accomplished in coéperation with the Field Museum of Nat- ural History of Chicago, by Dr. C. F. Millspaugh, Curator (16) of Botany of that institution, and myself, in an expedition to the eastern islands of that archipelago during February and March, and during November and December this work was further continued by Dr. Marshall A. Howe and Mr. Percy Wilson, Administrative Assistant, in an expedition to the southeastern islands, a region hitherto quite unknown botan- ically; they returned to the Garden on January 5, bringing back very large collections both of land plants and of marine algae, and this expedition will essentially complete the sur- vey of that archipelago, which has extended over several years. The island of Montserrat, British West Indies, was explored by Dr. John A. Shafer, Museum Custodian, during January and February, and this trip yielded important addi- tions to the museum and herbarium. The exploration of the island of Jamaica was continued by Mrs. Britton and my- self during September, in coéperation with the Department of Public Gardens and Plantations of that island, and import- ant additions to the collections in all departments were ob- tained. Dr. Arthur Hollick, a Museum Curator, has con- tinued at intervals during the year, the collection of fossil plants from the Cretaceous formation of the Atlantic coastal plain, special attention having been given by him, in coépera- tion with Professor E. C. Jeffrey, of Harvard University, to the lignitic deposits at Kreischerville, Staten Island, which have yielded material shedding much light on the features of the flora of that geologic epoch; the results of these studies will soon be published as Volume 3 of the Garden’s Memoirs. There is no doubt that exploration carried on either by members of the staff or by trained collectors under their direction, is the most profitable way in which additions can be made to the collections in all departments of the Garden, and it is most desirable that funds be secured to continue this work especially in the West Indies and Central America. An exploration of the republic of Panama, in continuation of some work done there by Mr. John F. Cowell, Director of the Buffalo Botanic Garden, on behalf of the New York Botanical Garden, in 1905, has been arranged for by the kind (17) aay of Mr. D. O. Mills, President of the Garden, and Mr. R. S. Williams has been detailed for this work, to leave the eo during January for an absence of about four months. Jt is much desired that expeditions to eastern Cuba, Jamaica and Santo Domingo, be provided for during the year. Investigations The collections of living plants, and of museum and her- barium specimens, have afforded increased facilities for inves- tigations by students, visiting botanists, and members of the staff, and records of work accomplished will be found in the reports of the several officers hereto appended. The appro- priation available for resident research scholarships has been expended with advantage, and the annual expenditure of a larger sum than our present income affords would be most desirable. As in previous years, the curators have been able to carry on some original investigation, largely, however, during time outside of their regular hours of attendance, the care, study and naming of the constantly increasing collec- tions requiring most of their required time. Visits have been made by various members of the staff to other museums and herbaria in the United States in order that we should be kept informed of progress at these institutions, and for the deter- mination of questions for which our own collections and library were insufficient. An account of publications issued by the Garden during the year will be found in the report of the First Assistant, hereto appended. These publications have been made possible largely by the aid of the David Lydig Fund, bequeathed by the late Judge Charles P. Daly- Research Scholarships Professor J. C. Arthur, of Purdue University, and his assis- tant, Mr. Frank D. Kern, were awarded scholarships for one month each, in January, to aid them in their investigations of the North American species of rusts (Uredinales), a group of parasitic fungi of immense importance in agriculture and hor- ticulture. Their first contribution to the ‘‘ North American (18 ) Flora” appeared March 6, 1907, as part 2 of volume 7, and their recent investigations are embodied in a succeeding part soon to be published. Miss Mary Perle Anderson, who held a scholarship from January 1 to April 1, 1907, is studying the Geographical Dis- tribution of the Ferns of Japan. Miss Anderson spent some time during the summer in consulting material in European herbaria. Professor Melville Thurston Cook, formerly Chief of the Department of Plant Pathology of the Estaciédn Central Agronémica de Cuba, was granted a scholarship from January x to April 1, 1907. He was engaged in studies of insect galls and in embryological investigation. While here he completed two papers, ‘‘ The Embryology of Ahytzdophyllum,” and ‘‘The Embryology of AAtzophora Mangle,’ both of which appeared in The Bulletin of the Torrey Botanical Club for 1907. At the termination of his residence at the Garden, Dr. Cook accepted an appointment under the Adams Act, as Plant Pathologist of the Delaware Agricultural Experiment Station at Newark, Delaware. Dr. Raymond Haynes Pond held a research scholarship from October 1, 1906, to April 1, 1907, and, on account of the nature of the problems, the grant was continued from April 1, 1907, to July 1, 1907. Dr. Pond investigated the problem of ‘* Solution Tension and Toxicity in Lipolysis,” and has published one paper on this subject in the American Journal of Physiology for July, 1907. A second paper has also been prepared. Professor F. S. Earle, of Herradura, Cuba, formerly Director of the Estacién Central Agronémica de Cuba, held a research scholarship during July, during which time he was investigating certain groups of the gill-fungi with a view to publishing them at an early date in the ‘“‘North American Flora.” Professor Earle has made important additions to the knowledge of the gill-fungi through his recent collections in Cuba. (19) Preservation of Native Plants A grant of $200 from the income of the Caroline and Olivia Phelps Stokes Fund for the Preservation of Native Plants, was made in the spring to Mr. Charles Louis Pollard, Secretary and Treasurer of the Wild Flower Preservation Society of America, to enable him to deliver a series of illus- trated lectures in ten cities and towns in New Jersey, New England and Canada, his illustrations being mainly drawn from the Van Brunt collection of colored lantern slides, the property of the Garden. Mr. Pollard has published an ac- count of these lectures in the August issue of our JouRNAL, and there is no doubt that much interest in the subject was aroused by them. Administrative The detailed oversight of the maintenance of grounds, buildings, collections and plantations, has been ably accom- plished by Dr. William A. Murrill, First Assistant, who has also been entrusted with the direction of the Garden at inter- vals during my absence from New York. As recommended by the Scientific Directors, the Board of Managers at their October meeting re-established the position of Assistant Direc- tor, and Dr. Murrill has been appointed to that post. Mr. Percy Wilson, Administrative Assistant, has continued in this capacity throughout the year, acting immediately under my own instructions and those of Dr. Murrill. My own time has been largely given to the general direction of the work of the institution, to the continuance of construction opera- tions and to the increase of the collections; as much of it as could be spared has been devoted to the study of collections brought in by the several exploring expeditions and to the preparation of manuscript for ‘‘ North American Flora.” I have also completed, with the assistance of Dr. J. A. Shafer, Museum Custodian, a descriptive work on North American trees which will soon be published, and my studies of Cac- taceae, in codperation with Dr. J. N. Rose of the United States National Museum have made progress. (20) Genera! Considerations As stated in my last annual report the Garden has now reached the stage of development which should soon cause it to take rank among the most important institutions of its kind. Compared with the sums already expended by the city and by the Board of Managers for construction, relatively small amounts for this purpose are still necessary, including the completion of the new range of public conservatories, commenced during last year, the building of additional road- ways and paths, and the necessary grading and drainage work, and the extension of the water supply. The annual allowances for maintenance are, however, as yet insufficient for a wholly successful up-keep of the institution, and it is most desirable that additional funds be procured. This ap- proaching need was recognized by the Finance Committee of the Board of Managers in 1905, andin November of that year an appeal for additional funds was made by that Committee recommending the increase of our endowment to $1,000,000. The matter was again taken up last spring by the Executive Committee of the Board of Managers and the appeal renewed. No considerable immediate results have been reached by either of these efforts, although there is no doubt that much interest has been aroused. The present city maintenance allowance of $75,000 and the Garden’s available income from invested funds, membership dues and other sources amount- ing to about $28,000 provide collectively an income for 1908 of about $103,000. It is estimated that the amount that is yearly needed to provide for a wholly satisfactory mainte- nance, a proper increase of the collections and the develop- ment of educational work is about $125,000. This would be obtained by the increase of the Endowment Fund to $1,000, 000, as recommended by the Finance Committee and by the Executive Committee. Reports Appended I submit also reports by the First Assistant, the Head Cura- tor of the Museums and Herbarium, the Honorary Curator of (21) the Economic Collections, the Librarian, the Head Gardener, the Superintendent of Grounds, and a schedule of expendi- tures under appropriations made by the Board of Managers. Respectfully submitted, N. L. Britton, Director-in- Chief. (22) REPORT OF THE FIRST ASSISTANT To THE DrrEecTOR-IN-CHIEF: Sir: Ihave the honor to submit the following report for the year 1907. Grounds The roads and paths of the Garden have been cared for as in previous years by employees of the Park Department. Borders, signs, guard rails, catch basins, water mains, and other matters connected with lines of traffic through the grounds have also received due attention, as detailed in the report of the Superintendent. Considerable pruning has been necessary along the roadways and on some of the paths. This has in every case been done with great care, and the wounds have been covered with coal tar. The condition of the plantations is given in detail in the report of the Head Gardener. The valley containing the herbaceous grounds, the region about the lakes to the north of the museum building, and the courts of the public conserv- atories have been much improved during the year. A vig- orous war has been waged against the muskrat with great success. By far the most serious damage that has occurred on the grounds during the year has been due to the ravages of a fungus disease among the chestnut trees, practically all of them having succumbed to its attacks. The well-known leaf blight of the plane-tree was unusually severe the past season, but its effects are not often lasting. The months of July and August were exceedingly dry and vegetation suffered severely, but by continual use of the watering cart the more susceptible plants were kept alive until the copious Septem- ber rains restored everything to its normal condition. A furious storm in December broke down a few diseased trees in the open and overturned two or three hemlocks on exposed cliffs in the forest, but the hemlock woods as a whole proved to be in excellent condition. (23) Insect pests have been successfully kept in check by spraying. The lakes were treated twice during the summer with copper sulfate to rid them of algae, the results being most satisfactory. Mosquitoes were less abundant than ever before, on account of the regular use of petroleum in catch basins and other breeding places. The living collections and wild plants have suffered the usual damage from lawless visitors, but this has not been of a serious nature except in a few instances. Only seventeen arrests were made the past year, as against thirty-five the year previous. Buildings MusEuM A number of new cases have been installed during the year to accommodate the large accessions to various collections. Photographs and postal cards of interest to visitors have been placed on sale with the guide-books and certain other Garden publications near the elevated railway entrance and in the Museum building. The number of visitors has perhaps been larger the past year than during any previous year in the history of the Garden. The holiday crowds are growing larger, the at- tendance at.public lectures is improving, and more botanists are consulting the library and herbarium. The various im- portant meetings held at the Garden also attracted scientific men from many parts of this country and Europe. CONSERVATORIES The public conservatories are perhaps in a more satisfactory condition than ever before. Considerable painting and re- pairing has been done both on the outside and inside of the houses. The palms and other tall plants have greatly im- proved under the new method of watering by means of a force pump. The large collection of cacti placed outside in the conservatory court on the south and the flower garden established on the north side added much to the appearance (24) of the range and attracted a great deal of attention from visitors. The propagating houses are also in excellent condition. House No. 3 is now devoted to the smaller specimens of the splendid orchid collection recently given by Mr. Oakes Ames, the larger plants being housed at the public conservatories. OTHER BuILDINGS The heating and power plant has been maintained in good condition at small expense. No accidents nor irregularities of importance have occurred in this connection. The stable and stable machinery are in good repair. A new horse for driving has been purchased and the one formerly used has been sold. Publications JOURNAL The Journal has appeared each month during the year, making a volume of 290 pages with 5 plates and 37 figures. BULLETIN Bulletin no. 14, by Dr. H. H. Rusby, ‘¢ An Enumeration of the Plants Collected in Bolivia by Miguel Bang. Part 4. With Descriptions of New Genera and Species,” was issued December 7, 1907, and contains 170 pages.

(29 ) REPORT OF THE HEAD GARDENER To THE DiRECTOR-IN-CHIEF : Str: Ihave the honor to submit the following report as Head Gardener for the year 1904. Systematic Collections Herbaceous Grounds. No alterations have been made in the arrangement of this plantation. There have been grown in the herbaceous collections during the year, including some still at the nurseries, 2,320 species. There have been added during the year 216 show labels. Fruticetum. There are now in this collection 1,442 plants, representing, including some few still at the nurseries, 693 species and varieties. ‘The completion of the grading in the area between the west lake and the driveway to the north permitted of the permanent planting of this tract, and plants representing the genera Sambucus, Symphoricarpos and Dier- villa were transplanted in accordance with the plan employed in the remainder of the collection. The collection of speci- mens of Wezgela and Adel/a, temporarily located in the vicinity of the honeysuckles, were transplanted to this newly graded area, and form a permanent group along the drive- way. The large triangle in the immediate vicinity was also planted with 29 specimens of the genus Vrburnum, removed from the triangle south of the Museum. ‘To the collections here have been added 198 show labels. Salicetum. This collection of willows in the north meadows remains as it was, with 45 species and varieties and 125 specimens. Deciduous Arboretum. There are in this collection, in- cluding those still at the nurseries and native to the tract, 255 species and varieties. The arboretum now contains in place 392 specimens. Pinetum. Including those still at the nurseries, there are now represented 270 species and varieties. Of these 190 are in place in the pinetum itself, represented by 850 specimens. There have been added 44 show labels. (30) Conservatories. There are now in the conservatories 9,219 plants, an increase of about 600 over the number grown in 1906. This, together with the increase in the size of the plants, has emphasized the crowded condition of these build- ings for some time past, and makes evident the immediate need for the completion of at least a part of the new range. This crowded condition is especially manifest in houses nos. 4 and 8, which are devoted to the smaller specimens of the tropical exogenous plants. House no. 4, which has hitherto served as an overflow house for plants which become too large for houses nos. 7 and 8, has itself become so crowded that there is not sufficient room for many additions there. There are many specimens at the propagating houses which might be placed on view in the public conservatories, were it not for this crowded condition. The following table gives the number of plants in each house: House no. 1 394 House no. 9 92 - 2 446 : Io = 460 a 3 312 ne II 261 - 4 440 “rz 748 : 5 1,519 ~ 13 515 te 6 808 - I4 641 - 7 = 749 7 15 1,099 es 8 735 In the conservatory collections, including those at the prop- agating houses, there are now 204 families, 1,393 genera, and 7,881 species and varieties, represented by 18,364 specimens. There have been 2,366 zinc and 102 lead show labels made for these collections, making a total of 2,468. Propagating Hfouses and Nursertes, A great part of houses nos. § and 6 have been devoted to the study collection of cacti, and the larger part of house no. 4 has been given up to the experimental work in charge of the Director of the Laboratories. It has been necessary to make use of a por- tion of this house to accommodate the ordinary collections. A part of the nursery has also been reserved for the use of the Director of the Laboratories. (31) From various sources there have been received during the year 1,235 packets of seeds. In the various plantations 284 packets have been collected. There are now in the propa- gating houses, including the cold frames, 9,145 plants. In the nurseries there are 2,627 specimens of woody plants, and 1,986 herbaceous plants. Labeling, Recording and Herbarium. Up tothe middle of May the work of this department was carried on under the direction of two garden aids, as described in my report of the previous year. At the above time, on the occasion of the resignation of Mr. Eggleston, the entire work of this department was assumed and has since been conducted in an efficient and satisfactory manner by Mr. Norman Taylor, gardenaid. Incarrying out this work, two men for the entire year and one for six months have been employed. The en- tire time of one of these employes has been used in the work of accessioning and making records, in making corrections on data labels, in the preparation of herbarium specimens, in the collecting of seeds, and other similar duties, the others have been employed in the manufacture of labels. In addi- tion to the above the assistance of one garden aid has been available for a part of his time, mainly in work on the trees along the driveways and paths. The following show labels have been made during the year : Herbaceous Grounds 216 Morphological Garden.... ........ececeeeeeenee aoe 53 Economic Garden ...... 294 onservatories 2,468 Pinetum...... .c.ceeseeees 44 Fruticetam 198 Trees along roads and paths 250 Conservatory pools 39 Conservatory decorative beds 296 3,858 Accession numbers 26,035-29,089 have been recorded (32) during the year, making a total of 3,055 accessions. The total number of plants derived from all sources has been 6,232, of which 3,416 were by gift, 342 from exchanges, 1,189 derived from seeds, 287 from our own collections, mainly from expeditions to the West Indies, and 998 by pur- chase; it will be seen that more than half of the plants secured during the year were obtained by gift. There have been prepared 620 herbarium specimens of cultivated plants, 230 from the conservatory collections and 390 from those outside. The following table gives the approximate number of species and varieties in the collections: alolics 7,881 Herbaceous Grounds 2,320 Fruticetum 693 Deciduous Arboretum...........ccecce.eccceuuecece 255 Pinetum 270 Salicetum 45 Viticetum 34 11,495 In addition to the above there are many species growing wild within the grounds which make the total number avail- able for study considerably larger. Miscellaneous Collections Morphological Garden. The collections here have been considerably expanded during the year, 43 additional spec- imen plants having been added, making a total now of 161. The bed devoted to the ecology of stems and branches has been enlarged, and five new beds have been opened. The new beds are devoted to: ecology of roots; ecology of leaves ; symbiosis; morphology of thorns; and modes of climbing. There have been added 53 show labels. Economie Garden. This collection, the initial work on which was done in the fall of 1906, has been greatly in- creased during the year. A detailed account of this collec- (33) tion appeared in the JouRNAL for August. There have been grown in this collection during the year, in 31 beds and along the brook, 230 plants, divided as follows: food plants, 141; medicinal, 65; condiments and relishes, 18; fibers, 6. For these plants 294 show labels have been supplied. American Desert Plants. The large rectangular plot on the terrace in front of the south entrance to the conservatories, formerly in grass, was used for the purpose of displaying a collection of plants from the American deserts. An account of this in detail appeared in the JourNnax for August. It was one of the features of the conservatories, and attracted much attention. There were used in making this display 560 plants, representing 7 families and about 200 species. Conservatory Lily Pools. The two pools in the court of the conservatories continue to be features of great interest. There were about 50 species and varieties of water lilies grown there, in addition to the two species of the royal waterlily, Victorta. The lead show label, which has proved so desirable for trees and shrubs and for the larger specimens in the conservatories, was used here during the summer in place of the zinc ones; 39 were placed in position. Conservatory Flower Garden. The large rectangular plots, formerly covered with sod, at the foot of the terrace on the north side of the conservatories, were in part converted into flower gardens. A detailed account of this feature ap- peared inthe Journal for May. The center of each plot was planted with a mixed collection of conifers, broad-leaved evergreens, and deciduous shrubs, the conifers largely pre- dominating, so that a green effect might be secured during the winter months. Around this central planting a border 8 feet wide was given to herbaceous plants. It was thought desirable to have show labels for the herbaceous plants, and 296 such labels were placed there during the summer. border of sod 2% feet wide surrounds the herbaceous plants. There were used in the planting of these beds: 1,000 conifers and broad-leaved evergreens, the gift of Mr. Lowell M. Palmer ; 500 deciduous shrubs; and 2,200 herbaceous plants ; (34) making a total of 3,700 plants. These flower beds attracted much attention during the summer. General Horticultural Operations The force available consisted of the following: 3 foreman- gardeners, 14 gardeners, 4 apprentices, and 18 laborers. Inad- dition to the above 1 driver for his entire time and 2 others dur- ing the mowing season were available for mowing and hauling. This force was distributed as follows: 1 foreman-gardener, 9 gardeners, and 2 apprentices were detailed to the conserva- tories, including the care of the decorative planting in the immediate vicinity; 1 foreman-gardener, 1 gardener, and 2 apprentices to the propagating houses; 1 foreman-gardener, 4 gardeners, and the 18 laborers to the outdoor work. The outdoor force was detailed as follows: museum tract, 2 laborers; conservatory tract, 1 gardener and 3 laborers; west border tract, I gardener and 2 laborers; fruticetum tract, 1 gardener and 3 laborers; herbaceous grounds tract, 1 gardener and 5 laborers; for miscellaneous operations, in- cluding the care of the arboretum and scythe work, 3 laborers. At the conclusion of outdoor work in the fall 2 of the gar- deners were transferred to the conservatories. The 2 remain- ing gardeners were employed for the rest of the year in the usual gardening operations needing attention at that time. In the matter of new park planting considerable was ac- complished. During the spring the following work was per- formed. The west border to the north of the Mosholu bridge approach was rearranged, the planting being extended along the approach wall to the road, the additional shrubs neces- sary for this work being obtained elsewhere in the grounds. At the Woodland Avenue bridge the abutment was planted with a miscellaneous collection of conifers and poplars, and the space between the path and the road of the approach was partly planted with the Japanese barberry. The planting in the rear of the fountain near the Museum was considerably extended by the addition of a number of lower growing coni- fers in front of the taller ones already in position. The plant- (35) ing around the marble work at the foot of the approach to the Museum has been rearranged, the plants of //ex crenata having been removed from their former position as a border to the conifers and used as a screen-planting on the sides of the en- closure, continuing that already there. During the fall the following work was carried out: Near the entrance to the elevated approach, in the strip separating the path from the road, a row of Japanese barberries was planted to prevent encroachment upon this place by pedes- trians and carriages. At the south gate a bed of Japanese barberries was planted around each pillar, extending consid- erably beyond the pillar in each direction, the barberries neces- sary for this work being secured from other plantations. The border in the corner near the elevated station was rearranged and thinned, the surplus being used in planting elsewhere. Portions of the south border, from which barberries had been removed for use elsewhere, were planted with other shrubs and rearranged. Eastward of the conservatories the ends of the grass strip separating the road from the path were planted with viburnums, taken from the triangle south of the Mu- seum, thus necessitating a rearrangement there. The natural border of alders on the north shore of the middle lake was reinforced and carried around to the bridge by transplanting a number of wild plants from the immediate vicinity. All herbaceous plantations, shrubs and young trees were carefully mulched with well-seasoned stable manure and leaf- mold at the beginning of winter. All manure needed has been obtained by supplying a dump for the use of the stables in the vicinity of the Garden, or by hauling from stables when our teams were not otherwise employed. These piles of ma- nure have been turned twice, and form excellent fertilizer and material for mulching. Large piles of leaves raked from the lawns have yielded much leaf-mold of superior quality. Investigations Mr. Norman Taylor, garden aid, in addition to his work on the cultivated plants, has continued his studies on the Potamogetons. 36) I have continued my studies on the grasses of North Amer- ica, in addition to work done by me in the cultivated collec- tions, especially in the orchid and pineapple families; the increasing size of the Garden collections in these families, due largely to explorations carried onin the American tropics, makes this work of great interest. Respectfully submitted, GrorceE V. Nasu, flead Gardener. (37) REPORT OF THE HEAD CURATOR OF THE MUSEUMS AND HERBARIUM To THE DIRECTOR-IN-CHIEF. Str: [have the honor to submit my report as Head Curator of the Museums and Herbarium for the year 1907: Accessions Additions to the collections were obtained as follows: (2) Purchase. Specimens mainly from the United States, Mexico, Central America, Asia and the Philippine Islands aggregate 5,690. (6) Gift. A total of 6,931 specimens, representing a wide geographic area and a variety of objects, was added to the collections by donors. (c) Exchanges. Specimens from Canada, the United States, Mexico, the West Indies, Colombia, Egypt and the Philippine Islands constitute a very large percentage of the total 7,763 secured by exchanges with other .nstitutions and with indi- viduals. (@) Exploration. Exploration in the Bahamas, Jamaica, Montserrat and Antigua, and on the North American main- land, was the means of bringing together 10,718 specimens. The collections were increased by 31,102 specimens. Museums The permanent museum equipment was increased by the addition of sixteen unit cases for the economic museum, and six table cases for the fossil plant museum; and by specimen jars as follows: Glass jars. (Specimen jar no. 2605, Whitall Tatum Co.) Diameter Height Number of jars 3. inches. 6 inches. 36 3 ac 8 oe 48 3% 66 Io 6c 60 4% ee 12 cc 72 Total, 216 (38) I. Economic Musgum. Specimens were added to all the exhibits of this museum, but the general plan of arrangement was unchanged except in the west wing, where the sixteen new exhibition cases were installed. The increase of the collections in the west wing necessitated their complete re- arrangement. II. Sysrematic Museum. The three elements comprising the systematic museum, namely, the Synoptic Collection, the Microscope Exhibit and the Local Flora, were increased by the addition of specimens or improved by the replacing of old specimens. No general rearrangement was necessary. III. Fosstr PLant Museum. About the end of the year six additional table cases for fossil plants were placed in the west hall of the basement. The whole exhibition space of the basement is now’ devoted to the fossil plant museum. The transfer of specimens, previously held in storage, to the new cases has been begun. The collections have been increased by a large number of specimens from the Creta- ceous deposits at Kreischerville, Staten Island, New York, from the Grand Gulf formation of Alabama and from several of the South Atlantic states. IV. Lasetinc. All new specimens added to the public exhibits of the several museums were furnished with printed labels. Several hundred labels printed during earlier years were rewritten and printed anew in order to have them con- form to improved styles adopted later. Herbarium I. MounTiInc AND CONSERVING OF SPECIMENS. About 49,000 specimens, selected from those received during the year, and previous years, were incorporated in the perma- nent collections. The specimens fall into two groups: (a) Flat or pressed specimens. About 47,000 specimens were poisoned and mounted on 36,184 sheets of herbarium paper, and distributed in the cases. (6) Bulky specimens. About 2,000 specimens of fruits, seeds, stems and other parts of plants too thick to mount on sheets were placed in boxes and distributed in the cases. (39) The permanent equipment for conserving bulky specimens was increased by the following supply boxes: Size of boxes Number of boxes 4 X 234% 1h inches ......... ees 1,000 54X55 XIy * 500 54X4 X2% * 500 S X5%ZX2% * 250 8 x 5% x5 i 250 16 X 5% X 5 “ 15 Total...... 25575 Fully 11,000 duplicate specimens were distributed, as exchanges, to several institutions and individuals in this country and abroad. JJ. ARRANGEMENT OF THE HERBARIUM. The increase of the herbarium necessitated considerable rearrangement of several plant groups. Forty-one standard cases were added to the herbarium equipment ; thirty-one of these were arranged in the large room at the extreme western end of the third floor, and the fungus collections have been placed in these cases. Ten cases were arranged in the main herbarium room to accommodate the additions made to the collection of flower- ing plants. Three special wall cases were built in the room formerly occupied by the collection of fungi to accommodate the rapidly increasing collections of mosses and ferns. Valu- able sets of specimens from tropical America, both from the Antilles and from the mainland were added to the permanent collections. Assistance and Investigations Dr. W. A. Murrill, First Assistant of the Director-in-Chief, has had charge of the collection of fungi. Through his efforts considerable additions to the fungus collections were made, largely through the determination of specimens, and he has prepared twenty-five duplicate sets of the commoner polypores of the region about New York City. He published an article on Philippine polypores in the Bulletin of the Torrey Botanical Club. Two parts of the North American Flora, including the polypores, were completed and one has been published as number one of volume nine of that work. ( 40 ) Dr. Marshall A. Howe, Curator, continued the develop- ment of the collections of algae and hepatics. He collected marine algae during part of January in Jamaica and spent part of November and all of December exploring the more southern portions of the Bahamas, and throughout the year continued his studies on the North American marine algae. Some results of these studies were published in several papers. Dr. Howe continued to edit TorREYA with the coéperation of Dr. Philip Dowell. Dr. Arthur Hollick, Curator, has had charge of the collec- tion of fossil plants. He prosecuted field work at Kreischer- ville, Staten Island, N. Y., investigating the Cretaceous flora in codperation with Professor Edward C. Jeffrey, of Harvard University. Dr. Hollick, with the voluntary assistance of Mr. Edwin W. Humphreys, a former student at the Garden, worked out the synonymy of the species to be represented in the new exhibition cases in order that the specimens may be rapidly and correctly labeled. Dr. P. A. Rydberg, Curator, has taken care of the collec- tion of flowering plants. He has also continued the prepa- ration of the manuscripts both of the Rosaceae for a forth- coming part of the North American Flora and of his Flora of the Rocky Mountains. Dr. Rydberg published severa] papers on North American plants and two addresses which he delivered in connection with celebrations commemorative of the two hundredth anniversary of the birth of Linnaeus. r. R. S. Williams, Assistant Curator, was occupied during the early part of the year in arranging and incorpo- rating the Leighton and Hasse herbaria of lichens with the permanent collections of the Garden, and also in studying va- rious West Indian collections of lichens. During the rest of the year Mr. Williams completed his studies on the second part of a large collection of Bolivian mosses, and also studied several smaller collections from various parts of tropical America. He studied the genera Alacromsrtrium, Campy- lopus and various genera belonging to the family Neckera- ceae for the preparation of manuscript for forthcoming parts of the North American Flora. (41) Mrs. Britton continued her voluntary oversight of the moss collection, directing the mounting of the Mitten herbarium, and naming the West Indian collections made by herself and others. She has also been giving critical study to several genera for the North American Flora. Professor L. M. Underwood, chairman of the Scientific Directors, until his death on November 16, continued to de- vote the time he spent at the Garden to the study and devel- opment of the collection of ferns and fern-allies. Dr. C. B. Robinson, Assistant Curator, was occupied mainly with work on the flowering plants of the Philippine Islands and with the compilation of a bibliography and the synonymy of the North American species and genera of Mal- pighiaceae. He spent five weeks exploring on the northern shore of the Gulf of St. Lawrence. Dr. Robinson continued as an associate editor of the Bulletin of the Torrey Botanical Club, compiling the «‘Index to Recent Literature,” helped with the museum work and demonstrated at the nature-study work carried on by the Garden in céoperation with the public schools of the city. Dr. J. A. Shafer, Museum Custodian, had general care of the museum building and its contents. During parts of Jan- uary and February he carried on exploration on the islands of Montserrat and Antigua, West Indies, while throughout the year he continued his studies on North American trees. The writer, in addition to curatorial duties, revised and completed manuscripts of monographs of the families Gerani- aceae, Oxalidaceae and Linaceae, all of which were pub- lished in part 1 of volume 25 of the North American Flora. Monographic studies on several other families are being car- ried to completion for publication in the same work. I have also continued my studies on the flora of the southeastern United States, more especially that of Florida. Respectfully submitted, J. K. Smaxu, Head Curator of the Museums and Herbarium. ( 42) REPORT OF THE DIRECTOR OF THE LABORA- TORIES To THE DiRkEcTOR-IN-CHIEF : Str: IT have the honor to present herewith my report for the year ending December 31, 1907. At the beginning of the year the exhibition of the New York Academy of Sciences, at the American Museum of Natural History, illustrating recent advancement in the various departments of science, begun on December 28, 1906, was still in progress, and remained open to the public until January 14,1907. This exhibition included the section devoted to botany, of which I had the honor of being chair- man, and some time was devoted to the supervision of the ex- hibits of the Garden and other exhibitors until the close of the exhibition and the return of the exhibits. During the first part of the year there was no regular Laboratory Assistant, but the duties of that position were dis- charged by Miss Alice Adelaide Knox, in return for the privileges extended to her as assistant to Dr. D. T. Mac- Dougal, of the Carnegie Institution. During the spring the experiments of Dr. MacDougal on the evening-primroses were terminated at the Garden, and the plants of his pedi- greed cultures were shipped to him at the Desert Botanical Laboratory at Tucson, Ariz. The arrangement with Miss Knox terminated on May 1, and on July 1, Miss Winifred Josephine Robinson, who is on leave of absence from her position as instructor in botany, at Vassar College, was ap- pointed Laboratory Assistant. In October, Miss Anne M. Lutz, cytologist at the Sta- tion for Experimental Evolution, at Cold Spring Harbor, . I., was appointed special assistant for three weeks. Her time was devoted to sectioning and staining material collected during 1905-06 from pedigreed cultures of the evening-prim- roses, for the purpose of studying their sporogeny and re- lated problems. Among the immediate results of a study of these preparations may be mentioned the confirmation of the (43) number of chromosomes in pure Oenothera Lamarckiana as 14. The agreement of this number with that obtained by Gates in this country and with Geert in Holland, removes all reasonable doubt on this important point. The mechanical labor involved in the preparation of material (collecting, imbedding, sectioning, mounting, and staining’ for such cytological studies as this, and for other histological re- searches is very considerable and often burdensome to the investigator, and the need of a permanent expert technician, or preparator, competent to do this work, is felt by several members of the staff. Such assistance would mean the saving of valuable time, and would thus make possible the under- taking and completing of more extended research than can now be accomplished. A rearrangement of the herbaria at the Garden has neces- sitated the occupation of the room hitherto known as the Phys- iological Laboratory by the cases of the fungal herbarium. This deprives the laboratories of a room much used, and of special advantage in several ways on account of its skylight. This change also emphasizes the need of additional cases suitable for the storage of some of the larger pieces of glass- ware and apparatus. Physiological experiments would be greatly facilitated by the construction of a mezzanine floor under the skylight and above the herbarium-cases in the room above mentioned. The investigations undertaken during the year have not necessitated the purchase of any large pieces of apparatus. The equipment has been enlarged by the purchase of nu- merous smaller pieces to facilitate the researches in progress, and the appropriation not thus used has been expended for stains, reagents, and microscopical accessories. Early in the spring the organization of the Morphological Garden was assigned to me. Several of the old beds have seen enlarged, and five new beds started, in which are em- shasized the ecological features, or the relation and adaptation of plants and plant organs to the various factors of environ- nent. These five beds illustrate, respectively : (44) . The morphology and ecology of roots. . The morphology and ecology of leaves. . The morphology and ecology of thorns. . Climbing organs, and modes of climbing. . Symbiosis, other than parasitism. At your request, an outline has been prepared for a special section in the Museum to illustrate physiological, morphologi- cal, and ecological phases of plant life. Such an exhibit will possess an especial teaching value, and enhance the use- fulness of the museum to teachers, and to classes in nature- study and elementary botany. Meteorological observations have been continued through- out the year as usual. In addition to the records of pre- cipitation and of soil- and air-temperatures, instruments for measuring the evaporating power of the air were installed on June 6, at three different stations. Station 1 was located on the dry, rocky, shaded knoll, just west of the propagating- houses; station 2 was in the low swampy region about 50 feet south of the stable; and station 3 was located in the ex- periment-garden, about six feet east of the instrument-shel- ter. These atmometers were installed and the records made in codperation with Dr. Burton E. Livingston, of the Desert Botanical Laboratory of the Carnegie Institution, at Tucson, Ariz. Dr. Livingston has established in the United States a number of similar stations, throughout a wide range of latitude, longitude, altitude, and distance from large bodies of water, and the comparison of the observations from these various stations will doubtless yield valuable information in regard to a most important, though as yet inadequately un- derstood ecological factor. The results of the observations at the Garden show that, for the period between June ro, 1907 and September 23, 1907, the amount of recorded pre- cipitation was .85 inches in excess of the evaporating power of the air (loss from the evaporimeter) at the propagating- house, and 4.48 inches in excess near the stable, while in the experiment-garden the evaporating power of the air was 2.78 inches in excess of the precipitation recorded. A complete wm bo NH (45) account of these observations and of their significance is pub- lished in the Journal of the Garden for December, 1907. The minimum temperature recorded for the year was — 2°, on February 6, and the maximum temperature 93° on July 8,18 and 25. The mean temperature for the year was, therefore, 45.50”. While the spring season, taken as a whole, was unusually cold and “late,” the month of April was ex- ceptionally warm, having a mean temperature of 48°, or 4.30 above the normal temperature for April for New York State. The total precipitation recorded was 47.01 + inches. The first fall frosts occurred during the first week in October. On October 3 luncheon was served in the Morphological Laboratory to the members of the Horticultural Society of New York and their guests. Covers were laid for about fifty persons, and the room was decorated with potted plants and cut flowers from the Conservatories. Early in December, circular letters were sent to all students who have been in residence at the Garden since its founda- tion, asking for information to be utilized in the compilation of complete academic records of such persons. This work cannot be completed until next year. My own investigations during the year have been devoted mainly to a continuation of researches on the effects of radium-rays on planis. Guarded pedigreed cultures of the com- mon evening primrose (Oenothera biennis) grown from seeds formed after an exposure of one or both germ-cells to radium- rays, have been carried through the first generation after exposure and interesting results recorded. The full signifi- cance and interpretation of these results can be ascertained only after the growth of the second generation during the coming year. The effects of these rays on indirect nuclear division, or mitosis, and on tropistic movements of plants have been studied, and reports of all three of the above lines of research were presented at the meetings of the American Association for the Advancement of Science, and affiliated societies, at Chicago, in December. Ten minor papers have been published during the year, in addition to sev- (46) eral reviews. With your consent, I have acted as collaborator for plant physiology for the journal ‘* Chemical Abstracts ” since October. With your permission, also, I have accepted an appoint- ment on the staff of lecturers in the New York City Board of Education Course of Public Lectures. There are only one or two other lecturers in this course offering lectures on purely botanical subjects, with the exception of the subject of forestry. The popular presentation of botanical knowledge ought to increase public interest in that science and help toward a realization of its value, and thus further the rapidly growing appreciation of the Garden on the part of the public. The buildings of the Tropical Laboratory of the Garden, at Cinchona, Jamaica, which were partially destroyed by the disastrous earthquake of the fourteenth of last January, have been repaired, but no investigators have been sent there since the earthquake. A total of 31 persons have had the privileges of the labora- tories, herbaria, and other collections during the year ending December 31, 1907, as follows: Investigators registered before January 1, 1907......... 7 Registrations at the Garden since January 1, 1907 .... 15 Total registrations. 22 Deduct for names counted twice 7 Number of persons registered 15 Additional persons to whom the privileges of the lab- oratories and collections have been granted...........

(51) REPORT OF THE LIBRARIAN To THE DirEecTOR-IN-CHIEF: Str: I have the honor to submit the following report on the Library for the year 1907. Upon my appointment as Librarian in October, I found the library in excellent condition in every respect; this reflected much credit not only upon my predecessor, but upon those who had the care of the Library during her absence in Europe for the five months immediately preceding my ap- pointment. According to a census of the Library, it contained at the end of the year 20,458 bound volumes, an apparent increase of only 96 volumes from the number stated in last year’s report. This has necessitated a careful review of the statis- tics of the Library for the past few years, and a comparison of the recorded additions during 1906 with the figures shown by the census taken at the end of that year; the result has convinced me that last year’s report contained a clerical error, by which the number of volumes was stated at 20,362 when it should have been 19,362. In this case, the actual increase shown by this year’s census is 1096 volumes, and this prob- ably approximates the actual number of additions. As in former years, no estimate has been made of the number of unbound pamphlets; nearly all of these, however, are in temporary covers, shelved, and catalogued, so that they may be consulted as conveniently as the bound volumes. The accessions during the year include 516 volumes purchased on the account of the special book fund, and 76 presented to the Garden. During the year 704 volumes have been bound; of this number 52 were the property of Columbia University, on deposit at the Garden. The additions to the catalogue have included about 3700 written cards. By this means the increase of the catalogue has kept pace with the growth of the Library; but although (52) current additions during recent years have been catalogued both by author and by subject, the older portion of the Library is very inadequately catalogued, for the most part by author only. As long as there is no increase of the Library staff, this unfortunate condition must continue; but with additional assistance the catalogue might be made much more useful than it is at the present time. Few alterations have been made in the exchange list during the year; these may be found by comparing the ap- pended list of periodicals with the one printed last year. The principal Library accessions have been published from time to time, as usual, in the Journal of the Garden. Respectfully submitted, Joun HeNDLEY BARNHART, Librarian.

Our plant must be also closely related to 7. yaouhensis Schlechter, which differs, however, if we follow the description, in having smaller leaves, a campanulate calyx of 0.25 cm. in length (author says 2.5 cm. long, which may be a misprint for 0.25), acute petals and a longer style. This last difference may be due to the fact that the flowers of our specimens were younger. Ixora bracteata Hochr. comb. nov. Charpentiera bracteata Vieillard in Bull. Soc.

I have not seen the original number quoted by Vieillard, but the description agrees exactly and our plant is identical with Balaxsa no. 3410 which bears in the Paris herbarium the name Charpen- tiera bracteata. As the description was very incomplete and not easily accessible I have here inserted a new one. Vieillard placed this plant in the Loganzaceae and it was a puzzle until Schumann transferred the genus to the 2udzaceae; but I think he was wron in identifying it with Pavetfa because it has the characteristic deeply bilobed stigma of Lxora.

Under the name &. amphidictyum Baker quotes in Mart. doc. ctt., a plant of Adartius no. 830, in the Kew Herbarium, that that plant is considered as the true &. amphidictyum. Inthe New York Her- rium the same plant of Martius occurs and bears the same number, therefore we thought it also should be &. amphidictyum. But after comparing it with the type of the Prodromus it proved to be quite different, the plant of de Candolle having much larger leaves and a long nude peduncle, bearing only a few minute bracts and at the top a small number of heads crowded together with short pedicels. Those heads are much larger than the ones of our plant. Unfortunately the state of our specimen does not allow us to make a complete description of it, but there is no doubt that if it is a Hupatorium itisanew species. Weare not yet convinced that it belongs to that genus, however, and the arrangement of the heads at the ends of the inflorescence branches suggests certain species of Vernonia. Having no good flowers we find it advisable to leave aside such a plant, wishing only to point out that Vard‘us no. 830 of the New York, as well as of the Kew, Herbarium has nothing to do with the type of de Candolle’s £. amphidictyum.

The latter differs, however, by its rather flat corymb, its flat leaves with wider teeth, by the wider and rather whitish involucral bracts and by the smaller heads. Our species suggests also B. sphaerocephala which differs also by its larger heads (up to 1.8 cm. in diam.), its non-alveolate leaves, and the flat corymb. Following the description our plant is related to B. grandicapitu- fata Hieron., but differs by its larger and acute leaves and by its pappus much exceeding the crown. HeELicHrysuM ARMENIUM DC.

N. Y. Bot. Gard. At first sight anyone might think that A. armentum and HZ. glanduliferum were two different species; but the numerous plants referred to H. armenium by Boissier show such a variation that we understand very well why he considered the whole lot as a polymorphic but unique species. However, as may be seen by the description, this particular form, called glanduliferum by Schultz seems so well characterized by its glands and the form of leaves and indumentum, that it is prac- tical to keep it apart as a variety. The specimen of the New York Herbarium is absolutely identical with the form of Schultz. The type of A. armenium DC. is Guaphalium armenium Fisch. et Mey., founded upon a plant of Szowitz, a specimen of which is in Herb. Boissier. From that plant I took the indications concerning the forma tyfica of the species. LaGASCEA HELIANTHIFOLIA H.B.K. Nov. Gen. Am. 4: 24; DC. Prod. §: 92 Orizaba (Afuller, no. 1277), in Herb. N. Y. Bot. Gard. L. helianthifolia differs certainly from ZL. /atzfola DC. as may be seen in the originals. The leaves of Z. latifolia DC. are sca- brous beneath, while those of eldanthifolza are softly tomentose. On the other hand Z. latifolia = L. suaveolens H.B.K.; DC., therefore it is an error to consider Z. suaveolens and L. helt- anthifolia as synonyms, as English authors do, for instance in Ind.

However, the characters given by Prof. Hieronymus and not agreeing with our species are the following: (1) ‘*Involucri squamae interiores 11— 12 mm. (the text bears cm. which must be a misprint for mm.) longae acutae glanduloso-punctulatae,” while ours do not exceed 8 mm., are never glandulose and the inner ones are rounded at the apex. (2) ‘*Paleis g-nerviis, in juventute pilosulis.” Ours are glabrous and 12-nerved. (3) ‘‘ Ligulae ca. 21 x5 mm. longae et latae.” Ours are aboutgx4 mm. (4) ‘‘Pappus squamulis 7-8, apice laciniato-dendatis, aristaque unica formatus.” Ours is com- posed of 2 spines and 2 truncate scales. (5) ‘* Corolla disci ca. 6 mm.,” while ours does not exceed 4.5 mm ( 296 ) All those characters show that Hieronymus’s plant must have more or less the same habit, but larger flowers and a different organization of the pappus.

There is no doubt that the two plants are two specimens of the same collection, so that we may consider them as coming from the same locality and bearing the same number. The Kew specimen ( 297 ) is to be found under Viguzera, but the absence of scales at the apex of the achene shows that it is a Helianthus. It is true that the achenes of the center of the heads are generally covered with bristly hairs and, at the apex, those hairs, exceeding a little the length of the fruit, may look like a very reduced pappus. But where the very caducous lateral bristles are preserved, one may see very distinctly that those bristles alone form the pappus. In that case, if hairs are developed on the fruit, it is obvious that they are inserted on the outer wall of the achenes. It is very inter- esting to note that in the same head some achenes are quite glabrous and some others are covered with bristly adpressed hairs. Our plant resembles HY. corntfolius and aureus H.B.K., with the original of which we compared it in Paris, but AZ. cornzfolius differs by its hirsute stems and wider and very scabrous leaves. : aureus differs also by its oblong leaves and larger heads with ligu- late flowers attaining 3 X 0.5 cm. length and width. The Viguzeras being very near allies of Helzanthus we wish to note also the species of that genus most resembling our plant. These are only Vigu¢era dentata Spreng. from Guatemala or V. decurrens and helianthoides from North America. But all of them are quite distinct. Lipochaeta lifuana Hochr. sp. nov.

( 298 ) Ins. Lifu, Nova Caledonia ( Véedllard no. 799), in Herb. N. Y. Bot. Gard., Paris et Kew. I first named this plant Weddelia lifuana (cf. Kew in Herb.) but the fruit, with its sharp edges and villous apex, is so exactly similar to the one of Lipochaeta integrifolia Gray, that I must place our plant next to it. The base of the leaves of Z. “éfuana shows also the three main nerves characteristic of the genus. However, Weddelia and Lipochaeta are very nearly related. The New York specimens show the two extreme shapes of leaves and bracts, the narrowest and the widest, but the Kew ones show all intermediate links, so that we cannot but consider them forms of the same species.

Ottonrs differs by its hairy akenes and by its leaves being shorter, wider and much more hairy beneath. Our species is also related to C. Zacatechiché Schlecht. and salmaefolia Hemsl., but both have hairy fruits and short, truncate pappus. SENECIO LEUCOPHYTON Philippi in Linnaea 28: 738. 1856 Chile prov.

It is very distinctfrom S. argenteus Remy and S. chzlents Lessing by its glabrous fruits and also by a slight difference in the tomentum, which looks like thin paper on S. argenteus and chitlensis, while it is here rather lke wool or cotton-wool. However later on Philippi omitted our species in his list of Plant. Neuv. Chilenas. It must have been forgotten.

The present paper is the result of field studies carried on along these lines for a number of years, together with an examination of specimens in the principal herbaria of the United States. Many helpful suggestions in the study of the phytogeographical (300) ( 301 ) problems have been obtained from Coville’s “Botany of the Death Valley Expedition,” Parish’s “Sketch of the Flora of Southern California,” and Hall’s “Survey of San Jacinto Mountain,” as well as from Merriam’s paper dealing with his system of life zones, which latter I have adopted. Acknowledgments are most heartily given to the following persons for the loan of material, or for assistance in determining questions of taxonomy and nomenclature: Dr. B. L. Robinson, Mr. F. V. Coville, Dr. J. N. Rose, Dr. J. K. Small, Dr. P. A. Ryd- berg, Dr. H. M. Hall, Mr. S. B. Parish, Dr. A. Davidson, Mr. W. F. Wight, Mr. C. R. Ball, Mr. P. L. Ricker, Mrs. K. Bran- degee and Miss M. A. Day. To Professor W. R. Dudley, who has courteously given much time and valuable assistance, and through whose advice and en- couragement I undertook the study of the southern California flora, and to Dr. N. L. Britton, who has given valuable aid in carrying on these studies, is due whatever merit this paper may possess. INTRODUCTION PHYSIOGRAPHY Southern California is the name popularly applied to that part of the State of California which lies south of Point Conception and the Tehachapi Mountains, a territory lying between 32° 35’ and 35° 45’ north latitude, and extending from the 37th to the 43d meridian west. Its western boundary is the Pacific Ocean, its southern Lower California, and its eastern the Colorado River, which separates it from Arizona. On the north the boundary is formed by the crosss ranges which break up the general trend of the Coast Ranges and the Sierra Nevada. Its line extends from Point Conception eastward along the Santa Ynez Mountains, Mount Pinos, and the Tehachapi Mountains to the southern ex- tremity of the Sierra Nevada, thence eastward to the southern boundary of Nevada. East of the Sierra Nevada the northern boundary is arbitrary, as the Mohave Desert merges into the desert regions northward and eastward with no definite line of demar- cation. The area comprised within these boundaries is approximately 113,250 square kilometers, a little over one fourth that of the entire State. The greatest width from east to west is 520 kilo- (302 ) meters, and from north to south 350 kilometers. Southern Cali- fornia covers an area somewhat greater than the entire State of Pennsylvania. If placed on the northern Atlantic coast it would extend east and west from Boston to Buffalo, and southward as far as Philadelphia. e topography is broken and irregular, with numerous moun- tain ranges separated by narrow passes or valleys of greater or less extent. The main axis of these mountains lies generally parallel with the coast at a distance of 40 to 120 kilometers inland. At intervals of 60 to 100 kilometers narrow passes divide this axis into several rather distinct sections. Of these sections the north- ernmost, which lies between Tejon and Soledad Passes, is composed of a series of comparatively low, chaparral-covered mountains, the culminating peak of which (Liebre Mountain) is only 1737 meters, above the sea. South of Soledad Pass, between it and Cajon Pass, are the rugged peaks of the San Gabriel Mountains, which rise abruptly out of the coastal valleys to altitudes ranging from 1800 to over 3000 meters (Mount San Antonio =3024 meters). The San Bernardino Mountains, although less broken and irreg- ular, reach even higher altitudes. In this range, which is separated y the narrow Cajon Pass from the San Gabriel Mountains, is the highest mountain south of the Sierra Nevada (San Gorgonio, 3428 meters). Extending southeastward from Mount San Gorgonio, at a much lower altitude, are the desert ranges, the Cottonwood and the Chuckawalla Mountains, which separate the Mohave and the Colorado Deserts. To the southward, again, between the Colorado Desert and the coastal region, rise the San Jacinto Mountains. The eastern base of Mount San Jacinto, the highest peak in this range, rests almost directly upon the low depressions of the Colorado Desert (Palm Springs, altitude 137 meters) while its summit, scarcely eight miles distant in an air line, rises with an almost sheer ascent to 3242 meters. South of the San Jacinto Mountains are the less rugged Palomar, Santa Rosa, and Cuia- maca Mountains. This series of mountain ranges divides the deserts from the coastal region, and is one of the principal factors which influence the climate of southern California. The arid desert country east of the mountains, comprising over one half the entire area of southern California, is separated by the Cottonwood and Chuckawalla Mountains into two distinct divisions, the Mohave and the Colorado Deserts.

RELIEF ( 303 ) The Mohave Desert, which lies to the north of the dividing ranges, is triangular in outline and covers an area of approximately 51,200 square kilometers. It is chiefly an arid plateau with an elevation of 300 to goo meters, but north of our limits is the low depression of Death Valley which is nearly 90 meters below sea level. The broad level expanse is broken here and there by short isolated ranges or “lone mountains,” the rocky barren slopes of which, save for their talus bases, rise abruptly from the floor-like plain. Between these elevations are numerous low depressions .’ The surfaces of these are frequently crusted over with the deposits of soluble salts, and the margins lined with characteristic saline vegetation. To the south of the Cottonwood and the Chuckawalla Moun- tains lies the Colorado Desert, which extends southward along the gulf slope of Lower California, and eastward into southern Arizona and northwestern Sonora. Within the boundaries of California this desert, the area of which occupies a little over 16,000 square kilometers, is principally the dry bed of a large inland sea or lake, with pebble-covered beaches that are still clearly discernible along the base of the surrounding mountains. At one time this depression was a continuation of the Gulf of Cali- fornia, from which it was cut off in comparatively recent times. This separation was accomplished partly, perhaps, by a slight elevation of the land between the vicinity of Yuma and the Cocopa Mountains, but chiefly by the delta formed at the mouth of the Colorado River, which latter carries great quantities of silt. Inward from the gravelly rim of the depression the character of the soil gradually changes from a sandy loam into the heaviest of clays, while the center, now covered by an accidental over- flow from the Colorado River, is normally a salt bed several feet in thickness. On the western or coastal side of the mountains the foot-hills and mountains give way here and there to valleys often of con- siderable extent. These valleys are mainly very fertile, supporting a luxuriant vegetation wherever water is plentiful, but areas of low alkaline soil, or dry gravelly mesas or washes are frequently interspersed. Along the southern base of the San Gabriel and the San Bernardino Mountains the original floor of the valley has been buried by debris of gravel and coarse sands, washed down by the winter torrents from the steep mountain slopes. Here ( 304) and there, however, isolated hills or elevated mesas, projecting above the talus, remain as indicators of the original sedimentary deposits. This large interior valley is separated from the low valley along the coast of Los Angeles and Orange Counties by the Santa Ana Mountains, and a series of low hills which connect them with the Santa Monica Mountains. North of this last range is the low coastal valley of Ventura County, the only other valley of any considerable area on the western side of the mountains. CLIMATOLOGY GENERAL DESCRIPTION There is great diversity of climate, due principally to topography, a factor which exerts a marked influence in southern California, since the principal mountain ranges lie transversely to the path of the prevailing winds and storms. Asa rule, however, the climate is one of scant precipitation and high temperatures, conditions that become more and more pronounced toward the interior, away from the ameliorating influences of the cool moist sea-breeze. The rainfall is chiefly confined to the winter and early spring months, the dry summer and autumn having almost continual sunshine. Precipitation i is greatest in the mountains, with an average annual rainfall in some localities exceeding 100 centimeters, and least in the Colorado Desert, where it is less than 5 centimeters in some sections. Fully as great extremes are found in temperatures. On a winter day, for instance, one may stand among blooming roses or in orange groves laden with ripe fruit, and watch the snow, driven by piercing winds, drifting about the rugged peaks of the neighboring mountains.

PHYTOGEOGRAPHIC FEATURES GENERAL DESCRIPTION Phytogeographically southern California is separated into three clearly defined floral divisions—the coastal slope, the mountain, and the desert. Each of these divisions has derived its charac- teristic plants from different floral elements. The species of the coastal slope are principally of Californian origin; the species confined to the mountains, boreal or of boreal ancestry; and those of the deserts, endemic or migrants from the Great Basin, Sonora, or Lower California. To discuss these different floras intelli- gently it is essential that some general system be followed. Engler’s! arrangement has many commendable features, but Merriam’s? system of North American life zones has been more completely worked out for this country and is therefore adopted. An outline of Merriam’s life zones for North America north of the tropics is as follows: Region Zone Area Arctic-alpine Boreal... . 0... ....005 Hudsonian Canadian 1Engler, A.

BOREAL REGION GENERAL DESCRIPTION In southern California the Boreal Region occupies the uppermost altitudes of the prominent mountain peaks, seldom descending lower than 2550 meters. It is therefore comparatively restricted, appearing only on the following peaks: Pinos, North Baldy, Pine, San Antonio, Sugarloaf, San Bernardino, San Gorgonio, San Jacinto, and Santa Rosa. e region is most extensive in the vicinity of Mount San Gorgonio and Mount San Ber- nardino, where it covers the high ridges connecting the peaks and the spurs leading from them. The three zones of the Boreal Region are less clearly defined than in more northerly territories, chiefly because the area covered by it is so limited. The presence of the Arctic-alpine Zone was first noted by Hall’, who discovered three characteristic Alpine species, Carex Preslit, Oxyria digyna, and Ranunculus Esch- scholizit on steep north slopes of Mount San Jacinto near perpetual snow. ‘To this scanty list Parish* has added Arenaria hirta verna and Aniennaria alpina from Mount San Gorgonio. The presence even of this small number of truly Arctic-alpine species is of con- siderable interest, for, as pointed out by Hall and Parish, they mark “the most southern known limit of the Artic flora on the North American Continent.” CANADIAN ZONE The two lower zones, the Hudsonian and the Canadian, are inseparable in southern California. Parish suggests that Pinus Murrayana characterizes the Canadian, and Pinus flexilis the 3Hall, H. M. A botanical Survey of San Jacinto Mountain. Univ. Calif. Publ., Bot. 1: 16. 1902. ‘Parish, S. B.

Ascending the mountain from Dry Lake one passes through pure forests of these two pines. Even the floor, which is composed of loose broken granitic rock, is almost bare of vegetation. Continuing upward the trees be- come fewer and more reduced in stature until it is difficult to walk beneath their gnarled branches. Finally, as the summit is approached, they become prostrate shrubs with such stiff compact branches that one may tramp over them with little dificulty. On the summit of Mount Pinos, where Pinus Murrayana has not been recorded, Pinus flexilis is found intermingling with Abies concolor and other upper Transition species. In fact it is impossible to detect two distinct belts of these two pines on any of the moun- tains. Notwithstanding the fact, therefore, that there are traces of Arctic-alpine plants, the only logical treatment demands that all the Boreal Region of southern California be placed in the Canadian Zone. In addition to the localities mentioned there is a fringe of the Canadian Zone on the western borders of Bear Valley, and Bluff Lake. Pinus Murrayana grows rather abundantly here, the lowest altitude (zoro meters) reached by this species in southern California. he characteristic trees and shrubs are: Pinus flexilis Ribes montigenum Pinus Murrayana Sericotheca concolor Populus tremuloides Phyllodoce Breweri Salix glaucops Sericotheca concolor and Phyllodoce Breweri extend northward through the Sierra Nevada to the southern Cascade Mountains, and to the mountains of western Nevada. All the remaining species extend to the Rocky Mountains, and one, Populus tremu- loides, to the northern Atlantic. The geographical distribution of these species demonstrates the intimate relation the flora of this zone bears to that of the more northern parts of North America. The origin of a boreal flora on these isolated southern mountain peaks is traceable to the influence of the Glacial Period. During that period central and southern California possessed a climate similar to that found to-day in the Puget Sound region. Perpet- (310) ual snow and glaciation extended down the mountain slopes to approximately 1800 meters altitude. The Canadian Zone, there- fore, probably was as low as goo meters or even lower, forming an unbroken belt, with the possible exception of San Gorgonio Pass, from the Sierra Nevada to San Pedro Martir Mountain. The receding of the ice and the consequent northern and upward migration of the plants left these isolated remnants stranded on the higher peaks. From the standpoint of regional distribution it is significant that only one species, Populus tremuloides, extends east of the ocky Mountains. It argues that an eastern and western area should be recognized. AUSTRAL REGION GENERAL DESCRIPTION The Austral Region occupies nearly the entire area of southern California, in the midst of which, on the tips of the highest moun- tain peaks, are situated the small isolated areas of typical Boreal. The three zones of the region are distinctly defined over large areas, but on account of great local variations in climatological conditions, due to slope exposure, sea-breezes, desert winds or other influences, isolated patches of a zone may be found far beyond its normal range. TRANSITION ZONE The Transition Zone, which is best characterized by the yellow pine (Pinus ponderosa), includes the principal forested area of the mountains. Its average range of altitude is from 1500 to 2700 meters, but deviations from this, chiefly due to slope exposure, are often considera The forests are eaaeail coniferous with a few scattered oaks, and along streams, poplars, willows, alders and maples. They are usually open and park-like, with a sparsely grass-covered floor, or with growths of low underbrush, which in rocky exposed places often develop into chaparral. Approximately 50 species of trees and shrubs have been re- corded within the Transition Zone, of which the following are characteristic: Pinus Lambertiana Ceanothus integerrimus puberulus Pinus ponderosa Ceanothus Palmert Burr.

A study of the geographical distribution of the species found in the Transition Zone shows that about sixty per cent. are limited to California (including San Pedro Martir Mountain) or extend only into the southern part of the Cascade Mountains; fifteen per cent. extend northward along the Coast or the Cascade Moun- tains of Oregon and Washington; ten per cent. are common to California and the Great Basin, and twelve per cent. occur through- out the Western Arid Area. To express the eR aa i ae conditions of this zone ac- curately it is evident that the divisions must reckon with the large percentage of ae Californian or endemic species. The simple statement that the flora belongs to the Transition Zone, as is usually the case, or that it is in the Western Arid Area, is misleading, as many of the species are not found in other parts of these divisions. It is essential that the areas recognized by Merriam, and based upon moisture, be divided int o sub-areas, which are chiefly the result of a third factor—g p | segregation. Without undertaking a discussion of the Ga Western Arid Area, the California mountains, on account of the large number of endemic genera and species, are recognized as a distinct division of the area. This may be termed the Sierran Sub-area. The Sierran Sub-area is best characterized by Pinus ponderosa Jeffreyi, Pinus Lambertiana and Heyderia decurrens. Its geo- graphical limits on the north are most satisfactorily defined by (312) the Klamath Gap. South of this gap the Sub-area occupies the Transition Zone of the Sierra Nevada and the inner Coast Ranges of central California, and extends through the mountains of south- ern California to Mount San Pedro Martir. n the Sierra Nevada the Transition Zone is fairly continuous, extending almost unbroken from the north Coast Ranges around the head of the Sacramento Valley, and southward along the west- ern slopes of the Sierra Nevada. The southern inner Coast Ranges and the mountains of southern California, on the other hand, are composed of isolated ranges. Hence great gaps occur in the Transition Zone of these ranges, which form barriers to the migration of species. Each of these sections is usually represented by several peculiar species, while others are con- spicuous by their absence. The Sierran Sub-area separates, there- fore, into three natural divisions, the Sierra Nevada District, the South Coast Range District, and the San Bernardino District. The latter includes the Transition Zone of the San Gabriel and San Bernardino ranges, and the mountains southward to San Pedro Martir. In this district there are several endemic species, such as Acer bernardinum, Ceanothus integerrimus puberulus, and Ceanothus Palmeri, while many of the species common in the northern districts are absent. Upper Austra ZONE General description.— The Upper Austral Zone in southern California is ae ase wholly by the Upper Sonoran Area, which include two distinct sections, the coastal slope and the different floral elements. The coastal slope species are predom- inantly Californian, while many of those on the desert slopes belong to the Great Basin element. Coastal slope-——The coastal slope of southern California is separated from the more northern parts of the Californian Sub- area® along the seaboard by Point Conception. The coast to 5The California Sub-area, which is equivalent to Engler’s “Innerkalifornische” zone of the HWestamenibanische Wisten- und Steppenprovinz,” is that part of the Upper Sonoran Area which lies west of the Aes Nev ada divide, and . name used by Parish (/. ¢.) includes parts of two zones, which seems illogical.

(333 ) the southward of this promontory turns directly eastward for 125 kilometers or more, paralleling the cross ranges which lie only a few miles distant. The coastal country is therefore protected from the northwest coast winds, and its warm southern slopes form a striking contrast to the cold bleak wind-swept mesas and hills about the promontory. A natural barrier is thus formed where a large number of species meet their southern or northern limits. South of Point Conception the entire coastal slope below the Transition Zone belongs to the Upper Sonoran, except the interior valleys and the southwestern part of San Diego County which are Lower Sonoran. Within this area, which we shall term the Southern California District, are over 100 species of trees and shrubs. study of the geographical distribution of these species shows that only four extend eastward as far as the Rocky Mountains, less than ten per cent. north to the Columbia River, and about the same number east to the Great Basin and Arizona. Nearly all the remaining species, or fully two ean of the entire number are confined to the California Sub-area, and of these about forty are chiefly confined to the Southern "California District. e most characteristic species of the Southern California District is Pseudotsuga macrocarpa. The geographical limits of this conifer almost coincide with those of the district. It does not extend northward beyond the Santa Ynez Mountains, nor beyond Fort Tejon in the mountains connecting with the Sierra Nevada. It is confined, however, to the upper altitudes, extending even into the Transition Zone. The following trees and shrubs are characteristic of the Southern California District, being almost or wholly confined within its boundaries: Pseudotsuga macrocarpa * Ceanothus Orcuttit Juglans californica Ceanothus megacarpus Eriogonum cinereum eanothus crassifolius Eriogonum fasciculatum folio- Vitis Girdiana losum alacothamnus fasciculatus Atriplex Breweri Malacothamnus Nuitallii * Clematis pauciflora Styrax californica flavescens Odostemon Nevinii Leptodactylon californicum glan- Ribes indecorum Grossularia amara * Eriodictyon crasstfolium (314) Grossularia hesperia Grossularia Parishii * Adenositoma sparstfolium osa Alderson * Xylothermia montana tomentosa Lupinus longifolius Lupinus Halli Rhamnus pilosa Ceanothus spinosus Trichostema Parishit Pentstemon cordifolius * Penstemon ternatus Pentstemon antirrhinoides Lonicera subspicata denudata Ericameria cuneata spathulata Ceanothus divaricatus eglandu- Ericameria Parishit losus Baccharis Plummerae Ceanothus oliganthus The species designated by an asterisk (*) are restricted to the southern part of the district. The general character of the vegetation is typical of a warm temperate climate which possesses moist cool winters and hot dry summers. ‘The predominant plants are evergreen xerophyllous shrubs with small thick leathery leaves of a dull or grayish- “green color. ey are invariably stiff compact growers, forming im- penetrable thickets that spread over the mountainsides in almost unbroken masses for many miles. The diversity of the flora, however, is considerable. The prox- imity of the sea and the irregularities of the topography, together with the resultant climatic conditions, are factors that have aide in the development of several sub-districts with distinctive floral features. Three of these floral sub-districts are recognized: the Littoral, the Coastal, and the Interior. The first of these sub- districts is the territory the within immediate influence of the sea, the second comprises the fog belt, and the third the chaparral belt of the interior mountains and foothills which are more or less cut off from the direct influence of the sea-breeze by hills or low mountains. Where passes or other connections exist between the Interior and the Coastal Sub-district the floral changes are gradual and difficult to separate. The Littoral Sub-district is confined to the immediate proximity of the sea, and is composed of four formations: the beach, the sand-dune, the salt-marsh, and the bluff. The number of shrubby plants wholly limited to this sub-district is small, Eriogonum parvifolium, Lupinus Chamissonis, and Ericameria ericoides on the sand-dunes, and Atriplex Breweri on the bluffs and edges of (315) salt-marshes being the complete list.6 Of these strictly maritime species, Eriogonum parvifolium extends northward to Monterey, and Atriplex Breweri to Santa Barbara. The other species are also confined to the California coast, but extend farther northward into northern California. he Coastal Sub-district comprises the valleys and rolling hills along the coast, and the coast slope of the foothills and mountains which separate them from the interior valleys. Its inland boun- dary extends along the southern slope of the Santa Ynez Moun- tains, the coast slope of the mountains of Ventura County, and southward through the San Fernando and Santa Monica Moun- tains to the Santa Ana Mountains, thence along the western slope of the Palomar Mountains where it blends with the Interior Sub- district. The principal plant formations of this area are the mesa and rolling hills, the alluvial, the oak-grove, the canyon, and the chap- arral. ‘The mesas and rolling grassy hills are characterized chiefly by the absence of woody plants rather than by any peculiar species. Along the inner boundary of this formation and merging with the Interior Sub-district are park-like groves of oaks. North of the Santa Monica Mountains, along their northern base, and in the Simi, Newhall and Ojai Valleys handsome trees of Quercus lobata abound. ‘This species does not extend south of the Santa Monica Mountains, but its place south of this range is taken by Quercus Engelmannit which, together with Quercus agrifolia, covers con- siderable area about Pasadena, Santa Anita, and Fallbrook. The following trees and shrubs are mostly confined to the Coastal Sub-district: Myrica californica Malacothamnus Nuttallit Juglans californica Quercus lobata Quercus Engelmannti Grossularia speciosa Grossularia amara Sericotheca franciscana Lupinus longifolius Ceanothus spinosus Ceanothus sorediatus Ceanothus oliganthus Ceanothus megacarpus Arbutus Menziesit Trichostema lanatum amona niveum ‘In addition to these true shrubs there are a number of suffrutescent peren- nials that are also confined to this sub-district. Among these may be men- tioned Cheiranthus suffrutescens, Sphacrostigma viridescens, Batis maritima, and Salicornia ambigua (316) Polygala californica Lonicera Ledebourit Acer californicum Baccharts pilularis Lithraea laurina Baccharis Plummerae A large percentage of these species, which are chiefly confined to the northern part of the sub-district, are common in northern California. They simply reach their southern limit within this sub-district. In this connection the influence of the Santa Monica Mountains should not be passed by unnoticed. This cross range although seldom reaching a higher altitude than 750 meters, exerts a marked influence on the northern and southern distribution of plants along the coast. The two oaks, Quercus lobaia and Quercus Engelmannit, are notable examples of species that are checked by this range in their northerly or southerly distribution. Several northern shrubs, such as Myrica californica and Baccharis pilu- laris, do not occur south of this range. e Interior Sub-district occupies the foothills and the typical chaparral of the interior mountains which are shut off from the direct influence of the sea-breeze by hills or low moun- tains. The western boundary is outlined by the Coastal Sub- district, and its inland by the Transition Zone of the higher mountains, or by the deserts in the lower mountains and passes. This sub-district extends from the Liebre Mountains southeast- ward along the coastal slope of the San Gabriel, the San Bernardino, the San Jacinto, and the Culamaca mountain The chaparral, of which the sub-district is eee wholly com- posed, is separated into several altitudinal belts. These alti- tudinal floral changes are very evident to one ascending any of the mountain trails. Along the base of the mountains, sometimes extending up their slopes several hundred feet and out over the footslopes, is a belt intermediate between the Upper and Lower Sonoran. Here the prevailing plants are Ramona stachioides, Eriogonum fasciculatum foliolosum and Senecio Douglasii. Ascend- ing the steep mountain slopes one passes into the typical chaparral. Adenostoma fasciculatum prevails through the lower altitudes in the eastern part of the San Gabriel Mountains, and in the San Bernardino and the San Jacinto Mountains, but on the Mount Wilson trail, which is intermediate between the Coastal and the Interior Sub-districts, Quercus dumosa and Ceanothus crassifolius are the predominating species. Further up the slopes these species gradually give way to others, of which Ceanothus divaricatus “SNIVLNOOW ONIGUVNUGT NVS ‘NOANVD NVWUELVM ‘VITOSIAWOHAY SON TV “a “Id ‘IA “10, ‘duvg ‘Log ‘(ACN ‘T1ag (317) eglandulosus, Uva-ursi tomentosa, and, in the San Bernardino Mountains, Uva-ursi pungens, are perhaps the most characteristic. altitudes and extends into the lower part of the Transition Zone. n the canyons, Quercus chrysolepis, Acer macrophyllum and Umbellularia californica seldom descend lower than 750 meters; but Alnus rhombifolia often follows living streams into the edges of the valleys. atanus racemosa is mostly confined to the lower altitudes, and occurs on the canyon floors, often following the washes well out into the valleys. The following trees and shrubs are mainly restricted to the Interior Sub-district: Pseudotsuga macrocarpa Ceanothus crasstfolius ibes indecorum Uva-ursi pungens Adenostoma sparstfolium Trichostema Parishit ylothermia montana tomentosa Pentsiemon. ternatus Lupinus Halli Penistemon antirrhinoides Ceanothus divaricatus eglandulosus Ericameria Parishit Desert slopes —The Upper Sonoran Area on the desert slopes of the mountains is commonly called the pifion and juniper belts, the two conifers, Pinus monophylla and / uniperus californica being the most characteristic species. The pifon occurs in the upper altitudes of the zone (1200-1800 meters). The juniper, on the other hand, occupies the lower altitudes (go0-1200 meters), and along the lower edges of the belt mingles with the yuccas and other shrubs characteristic of the Lower Sonoran.’ In the Provi- dence Mountains Juniperus utahensis replaces J uniperus cali- fornica. This is the only locality where this species enters into our territory, but in the Panamint Mountains it also replaces Juniperus californica, and extends from there eastward over south- n Nevada and Utah. Each of these species may be considered as representing a distinct floral district. everal trees and shrubs which belong properly to the Intra- montane district penetrate through Tejon Pass and extend in a 7The juniper belt is retained in the Upper Sonoran with reluctance, for over a large part of the belt the associating species are predominantly Lower Sonoran.

The normal flora of the desert slopes is modified in this section by the presence of such species as Pinus Sabiniana, Quercus Douglasit, Grossularia quercetorum and Aesculus californica. ong the Mexican Boundary a number of Peninsular species enter the flora in the pinion belt. Of these Pinus guadrifolia is the most noteworthy. This nut pine, which almost entirely replaces Pinus monophylla a few miles below the international boundary, occurs sparingly as far north as the Santa Rosa Mountains. e following are the characteristic Upper Sonoran trees and shrubs of the desert slopes: * Pinus monophylla Isomerts arborea globosa *Pinus quadrifolia *Kunzia glandulosa Juniperus californica *Rhamnus cuspidata Juniperus utahensis * Ceanothus vestitus Ephedra viridis Malacothamnus Fremontii *Quercus Alvordiana *Fremontodendron californicum *Quercus Dunnit Fraxinus velutinus *Quercus turbinella raxinus anomala Eriogonum fasciculatum polifolium Diplacus aridis *Eriogonum Heermanti tenotopsis interior *Odostemon Fremontii The species designated by an asterisk (*) are confined to the upper or pifon belt Lower AustRAL ZONE General description—-The Lower Austral Zone in southern California is represented by the Lower Sonoran Area. It includes all of the desert regions below the juniper belt, and protrudes through the lower passes into the hot interior valleys of the coastal slope. It also extends northward along the coast of Lower Cali- fornia to the vicinity of San Diego. Three floral elements enter into the composition of the Lower Sonoran in southern California, the Great Basin, the Sonoran, and the Peninsular. In the Mohave Desert many of the chav. teristic species are of the Great Basin element, in the Colorado Desert the Sonoran and the Peninsular species predominate, and at San Diego the Peninsular. Unfortunately the Lower Sonoran Area has not been sufficiently explored to warrant its division into sub-areas. Each of the southern California sections Butt. N. Y. Bor. Garp. Vou. VI. Pu. G.

Interior valleys —In the San Fernando, the San Bernardino, and the San. Jacinto Valleys, the fan-like footslopes that spread over the valleys from the bases of the steep mountain slopes, and the dry washes leading from the mouths of the canyons give rise on their semi-arid gravelly slopes to a low shrubby type of vege- tation resembling that of the desert in its xerophytic habit. The upper parts of the footslopes, as has been previously stated, are intermediate between the Upper and the Lower Sonoran, but the dry washes produce a typical Lower Sonoran flora, that often spreads over the greater part of the footslopes. Following is a list of characteristic Lower Sonoran trees and shrubs of the interior valleys: Salix vallicola Populus Fremontii *Strombicarpus pubescens *Prosopis glandulosa Opuntia bernardina Opuntia Covillei *Chilopsis linearis Gutierrezia divergens Ericameria pintfolia * Encelia farinosa Vigutera Parish Bebbia juncea Lepidospartum squamatum Tetradymia comosa The species designated by an asterisk (*) occur only in the eastern end of the San Bernardino Valley or in the San Jacinto Valley, and of these only Encelia farinosa is common. San Diego district—A large number of peninsular species of shrubs and herbaceous plants extend into southwestern San Diego County which give a floral aspect quite unlike that of other parts of the coastal slope. The following is a list of peninsular or desert species recorded from the vicinity of San Diego: Ephedra californica Yucca mohavensis Atriplex canescens Isomeris arborea Opuntia prolifera Opuntia californica Lycium Richit Lycium Andersonu Wrightir Prosopis velutina Cneoridium dumosum Acalypha californica Tricherostigma miserum Simmondsia californica Adolphia californica Lycium californicum Hymenoclea monogyra Gaertneria chenopodifolia Iva Hindsiana Viguiera laciniata (320) In addition to the typical Lower Sonoran species there are a number of other shrubby species peculiar to the San Diego region which are often the principal components of the chaparral. These species are: Cercocarpus minutiflora, Adenostoma fasciculatum ob- tusifolium, Ceanothus verrucosus, Xylococcus bicolor, and Coma- rostaphylis diversifolia. Pinus Torreyana is also restricted to this, with the exception of a small grove on Santa Rosa Island. Mohave Desert—The Lower Sonoran Area occupies nearly the entire area of the Mohave Desert, only in the upper altitudes of the mountains is it replaced by the juniper and pion belts of the Upper Sonoran. Wherever the soil conditions are favorable Covillea tridentata predominates. This shrub, commonly known as the “creosote bush,” is the most characteristic species of the entire Lower Sonoran Area, at least in the arid parts; but, on account of its wide range and its association in the various regions with markedly different floral elements, it cannot be utilized in segregating phytogeographical districts. Along the upper edges of the Covillea belt, and often extending into the edges of the juniper belt, are a number of characteristic desert shrubs, such as Grayia spinosa, Tetradymia spinosa, Tetra- dymia stenolepis, Amygdalus Fremontit and Adelia neo-mexicana. Associated with these is the tree yucca (Cleistoyucca arborescens), locally known as the “Joshua tree.” The great stretches of this desert yucca that spread over the gradually sloping plains resemble ee orchard tracts, and form a prominent feature of the landse The following Lower Sonoran trees and shrubs have been re- corded in the Mohave Desert within the limits of our territory: * Ephedra nevadensis *Echinocactus Lecontei * Ephedra californica *Echinocactus polycephalus * Yucca mohavensis Menodora spinescens Cleistoyucca arborescens Adelia neo-mexicana * Populus Fremontit Ramona pilosa *Salix vallicola Ramona capitata *Salix argophylla *Lyctum Cooperi Eriogonum Plumatella Lyctum Andersonit * Airiplex lentiformis Salazaria mexicana * Atriplex polycarpa *Chilopsis linearis * Atriplex confertifolia * Hymenoclea Salsola Atriplex Parryi Gaertneria eriocentra PL.

Colorado Desert——Covillea is also the predominant plant over the dry mesas of the Colorado Desert. Above this belt is an area corresponding to the yucca belt of the Mohave Desert, but com- prising a very different group of plants,® of which Agave deserti is the most characteristic. 8Parish, Bot. Gaz. 36: 222. 1903.

Type locality: “Shasta Valley, N. California.” Distribution: Cascade Mountains of southern Oregon southward through the Sierra Nevada and southern California to San Pedro Martir. The separation of this pine from typical Pinus ponderosa (327) is often dificult in southern California. Some trees with plated bark have small cones, and others have cones fully as large as any of the variety. Both extremes also occur on trees with the darker furrowed bark. In almost any locality, but especially in the vicinity of Green Valley, San Bernardino Mountains, it is possible to gather a series of cones ranging in size from the typical to that of the variety.

Type locality: “Near San Pasqual, southern California.” Distribution: Monterey County and the southern Sierra Nevada southward to the vicinity of Alamo, Lower California. In southern California the Spanish bayonet is common throughout the chapar- ral covered areas of the coast slope; it also occurs in the pinon belt of the desert slopes. A purple flowered form was collected by the writer (3547) in the foothills of San Diego County. In the vicinity of Fort Tejon (Abrams (9 McGregor 270) a more compact form, with flowers scarcely half the normal size, grows associated with typical plants.

Type locality: “Most abundant and grows to its largest size on the Mohave Desert.” Distribution: Northwestern Arizona and southwestern Nevada westward through the Mohave Desert and southward along the western border of the Colorado Desert to northern Lower Cali- fornia, where it extends westward into the coastal region in the vicinity of San Diego. This species is said to have been collected by Parry near Monterey, but we strongly suspect that this is an error through confusion of labels. Parry’s plants in all probability came from San Diego, for so far as we are aware the plant has not been found in the coastal region north of this locality.

Pl. 9: pl. 878. 1852 Type locality: “Santa Clara River, near Beneventano [Ven- tura], California.” Distribution: British Columbia and western Montana, south- ward throughout California. The mountain forms often develop narrow leaves that approach P. angustifolia, but there seem to be no stable characters that warrant their separation as a distinct variety or species. In southern California this species occurs in the Upper Sonoran on the coastal slope, and in the Transition and the lower altitudes of the Canadian Zones. In the Lower Sonoran of the interior valleys, at San Diego, and on the deserts, it is replaced by P. Fremontit. Specimens examined: Sulphur Mountain Spring, near Santa Paula, Abrams && McGregor 58; Monrovia Canyon, San Gabriel Mountains, Dudley, Nov. 20, 1907; Bear Valley, San Bernardino Mountains, Abrams &F McGregor 738. 2.

Type locality: “On Deer Creek at ‘Lassen’s’ in the upper Sacramento Valley.” Distribution: Sacramento Valley south to northern Lower Cali- fornia, and eastward to southern Colorado and western Texas. In southern California this species occurs along most of the streams of the interior valleys, seated the coast in San Diego County; it is also abundant in the canyons on the desert slopes of all the mountains. A form an pubescent twigs, foliage, and peduncles, which occurs on the delta of the Colorado River, may prove worthy of recognition when more complete material is at hand. My own specimens from Elsinore Lake are fully as pubescent as the delta plants, but specimens from Cajon Pass (Abrams (Ff McGregor 695) are only sparsely so, thus approaching the typical form which is glabrous.

Distribution: Streambanks in the Sacramento and San Joaquin valleys, southward into southern California. This variety differs from the true Salix nigra in its glandular stipules, and obovate or rounded instead of ovate bracts of the staminate aments. Speci- mens from the Colorado Desert (Abrams 3195) have the bracts of the staminate aments glandular-toothed.

Type locality: California, probably in the vicinity of San Fran- cisco or Monterey Distribution: Valley of the Rogue River, Oregon, southward through the Coast Ranges and on the western slope of the Sierra Nevada to the mountains of San Diego County. In southern California the laurel is frequent in canyons or on shaded slopes in the upper part of the chaparral belt and in the lower Transition, but is usually reduced to a small tree or arborescent shrub. Umbellularia is one of the many genera peculiar to the California Sub-area, and is a good example of the uniqueness of the flora.

The species proposed by Greene do not seem valid, at least so far as the plants of the main- land are concerned. I have examined critically all the species enumerated above except D. saligna with the result that I feel constrained to reduce them to synonymy. There is variation in foliage, but this is often marked in a locality where the character of the soil or moisture vary, and seems to be an ecological variation.
