Sequence of Orders of Dicotyledons (Sympetalae excepted), 1867-1935. OS Rhoeadales are called Papaverales in Gray's Manual and also in Britton and Brown’s Flora. Instead of Opuntiales, Warming and also Hutchinson used the form Cactales. The names Passiflorales, Myrtales and Umbellales, as used by Bentham and Hooker, seem preferable to the names of Rendle. The termination -florae, as in Thalamiflorae, might well be reserved, as by De Candolle and — — by Bentham and Hooker, for groups of Angiosperms larger than orders, if such become established. If we make such nomen- it read as follows: — clatural changes only, Rendle’s list of orders mig Ranales, Papaverales, Sarraceniales, Parietales, Passiflorales, Guttiferales, Malvales, Euphorbiales, Geraniales, Rutales, Sapin- dales, Celastrales, Rhamnales, Rosales, Myrtales, Cactales, Um- bellales. Rendle’s classification clearly combines ideas from the great his- yart aa — toric systems. What changes would be needed 1f we adopt in ideas from Hutchinson and other botanists? An answer 1s at- tempted in the following arrangement : CARPELS SEPARATE OR SINGLE A, Magnolia Group Kanales Rosales Proteales? Carrets UnNirep, RARELY SINGLE Placentation mostly Basal or Parietal, rarely Axile B. Ulmus Group . Cistus Group Hamamelidales Parietales Urticales Cactales (incl, Aizoac.?) Euphorbiales?

SvENSON I¢xtensive notes on the vegetation of Middle Tennessee, covering an investigation of several years, have now been completed and will appear as a Brooklyn Botanic Garden Contribution early in the spring. Accompanying these notes are several drawings by Miss Maud H. Purdy, in her characteristically excellent and ac- curate manner, which will contribute greatly to an understanding of species in the groups which have been treated in the South, where as yet only a small proportion of the species of flowering plants have been adequately illustrated. Two extensive groups of sedges, Bulbostylis and Fimbristylis, have been completed for North America (including the West In- dies), and the characteristic flowering spikes and fruit of these plants have likewise been illustrated by Miss Purdy. In April of this year the John Simon Guggenheim Memorial Foundation gave me a Fellowship for investigation of the relations of plants of the coast of Ecuador and Peru to those of the Gala- pagos Islands in the Pacific Ocean, 600 miles to the westward. With all the emphasis that has been placed on the Galapagos Islands since the time of Darwin's visit in 1834, it is strange that so little attention has been paid to the coast of South America. Here, as I have previously pointed out,! grow a considerable num- ber of the plants formerly believed not to occur outside the Gala- pagos Archipelago. Such plants occur chiefly in the desert coastal area of Ecuador and Peru, centering on the Gulf of Guayaquil. Since this area suffers from severe drouth for eight months of the year, it must be visited by the botanist during the period when more or less rain falls, from January to April. The scenic character of the Andes and their much more agreeable climate and luxuriance of both tropical and temperate mountain vegetation, in contrast to the severe climate and scrubby vegetation of the coast, explain why the Ecuadorean littoral remains almost entirely unknown to bot- anists. It may be asked, what is the significance of this investigation ? ! Brooklyn Botanic Garden Contributions No. 69, Plants of the Astor Ex- pedition, 1930. LOO Briefly, the Galapagos Islands are one of the focal points in discus- sions of the yet unsolved problem of the origin of species. Vol- umes have been written on the variation of birds, tortoises, lizards, and even plants within this strange group of lava-strewn islands which, from the time of Darwin, have been compared to the world ar regions, these islands are — in its beginning. Outside of the po probably the largest group without an aboriginal human popula- tion. This fact undoubtedly accounts for the thousands of giant tortoises—almost exterminated recently by man—and the remark- able tameness of the birds. Since the prevailing wind and ocean irection of the an currents move from the Ecuadorean coast in the ¢ Galapagos Islands, it is assumed that the lowland flora of the Gala- pagos Islands has, in general, been derived from the South Ameri- can continent. Because of this relationship it is of great impor- tance to find out whether the species-variations in plants of the mainland are similar to those of the islands. Toward the solution of this difficult problem my forthcoming investigation along the coast and in the low mountain ranges of Ecuador and northern Peru should at least make a beginning. It is expected that sev- eral thousand specimens will be collected for study at the Brook- lyn Botanic Garden and for distribution to similar institutions.! GENETICS Experimental variations in Nephrolepis By Ravru C. BENEpDICT During 1940, studies have been continued on variation in the Fern-genus Nephrolepis, as well as upon other genera in which variation and speciation problems are of interest. Maintenance of the collections, both in the greenhouse and in lath shelter, has been the chief activity along this line during 1940. Economic PLANTS By Ratpo H. CHENEY 1. A study of the flavor qualities of the varieties of Mentha was continued. Svenson sailed for Ecuador on January 31, 1941 on S. S. Santa 1 Elena, of the Grace Line. (/:ditor) 101 2. The potentialities of the species of Passiflora for beverage pur- poses were investigated. 3. Histo-pharmacological studies of the effects of caffeine on the heart of the frog were made. Re OR OT Eee eu RA LOR OR eu Big INSTRUCTION FOR 1940 To THE DIRECTOR: I present herewith the report of the work of this department for the year 1940, ATTENDANCE Grounds.—The attendance on the grounds in 1940 was some- f 1939—in fact, less than in any year since LY what less than that « 1936, when there was a decrease from the figures of 1935. The yearly figures from 1935 onward are as follows: 1935—1,624,805 1938—1,726,119 1936—1,567 ,304 1939—1 798,029 1937—1,691,835 1940—1 687,564 To evaluate definitely the various reasons for this rather sudden decline in attendance in 1940 would require a thorough study of the whole situation. It 1s obviously a very complicated problem, involving such factors as the general weather conditions as com- pared with those of other years, the depressing and distracting international situation, and the effect of the World’s Fair. Nevertheless 1f more than a million and a half people visit the Garden each year, that fact alone would seem ample justification of the existence of the Garden. The attendance in 1940 was more than 4 times what it was when I first came to the Garden in 1921— namely 404,889, Monthly attendance—In spite of the fact that the attendance 1€ — for the whole year showed a decrease, the figures for three of t as follows: months exceeded all previous records 1940 Highest Previous Record and Year JUN Gite eve ewe es dee ow ee 225,489 193,902—1939 Pe peed esa bare 162,907 159,043—1938 Se pienet Fb beeen a bad boa 168,233 154,295 —1937 Week-end attendance—tThe largest week-end attendance was that for May 11-13 were at their best. 52,796 persons visited the Garden that week- as usual, when the Japanese cherry blossoms end, a figure which compares favorably with the highest all-time week-end record; i.e., 56,145, during the week-end April 30—May 1, 1939, Conservatorics—The attendance at the conservatories for the year was 146,643 largest monthly figure was that for the month of May—31,946— an average of more than 12,000 a month. The which averages more than one thousand people a day for the month. These figures compare favorably with previous records. Classes and Lectures——TVhe combined atendance at classes and lectures was 108,368, a slight increase over that of last year—104,- 312. The following table shows other attendance data.

This will readily be seen by a glance at the figures for the last few years. Year Total Adult Registration 1932 ¢ 1933 823 1934 927 1935 907 1936 973 1937 802 1938 761 1939 725 1940 1,359 Such a phenomenal increase must of course have its cause, or causes. The policy of the Garden to offer courses to city institu- tions as part of its “ service to the City” is one of these causes. When the Garden commenced, back in 1913, its educational pro- gram of instructional classes offered to the public, certain courses were modelled especially for the needs of teachers in the New York City School System. The response has always been gratifying. In the fall of 1940, a special nature study course, offered by Miss Shaw and the Department of Elementary Instruction, brought 350 teachers to the Garden. A new combination course, planned espe- cially for teachers in the schools and entitled “* Nature Science Garden Course,” was offered by Miss Shaw and Mr. Marvin N. 3rooks, Director of Nature Education, Board of Education, N. Y. C. Forty people enrolled for this course. aave been offering a course to et For the past fourteen years we a course consisting nurses-in-training in the Brooklyn Hospitals mainly of a study of medicinal plants as they are growing on the grounds and in the conservatories of the Garden, supplemented by a laboratory study of plant tissues and physiology, with the help of the compound microscope. This course started with a few pupils in 1927. During the years it has been gradually increasing in favor with the hospital authorities. In 1940 five hospitals sent their students—331 in all. These hospitals were: Kings County, Prospect Heights, St. Johns, Jewish, and Cumberland. 105 Further, as part of its cooperation with the City, the Garden this year offered courses especially designed to assist employees of the Park Department. A course in general gardening was conducted in the fall by Mr. Free, our horticulturist, which was elected by 87 members of the Park Department. Courses in trees and shrubs for these men were also conducted in both spring and fall by Mr. Charles F. Doney, assistant in Woody Plants, and by the writer. Forty-one members of the Park Department registered for these courses. In addition to the adult courses referred to above, the Garden offers ae courses (““A” courses) for its members and the general public. With the exception of course A38, consisting of 3 ae on Plan Evolution by Dr. Alfred Gundersen, Curator of Plants, for which 60 people enrolled, registration in these has been about as usual. — In accordance with the cooperative agreement between the Gar- den and New York University, Mr. Arthur Davidoff, a graduate student in that institution, did work in our laboratory in Forest Pathology, during the school year 1939-40. fo, Work witn High ScHooLs The New York City High School curriculum, as at present con- stituted, includes a course in general science for the freshman year. In the succeeding years pupils may elect courses in advanced biol- ogy, chemistry, or physics. As a result, courses in botany as a distinct subject are no longer given in any high school, with the exception of one where, we understand, about 75 pupils are now taking a course in botany. — In spite of this situation we have had several high school classes here during the past year. The Biology Department of the Girls Commercial High School came for a lesson in plant propagation. Among other classes was one in physiography from the same school, which came for a lesson on the glacial boulders and other results of glaciation in the Garden. The members of a science club at the Alexander Hamilton High School came for a series of lessons in plant propagation and grafting, in which our Department of Elementary Instruction cooperated. About 300 pupils of the department of biology of the Abraham Lincoln High School came 106 to the Garden on Saturday, May 11, for a“ field day.” They were divided into groups of about 20 each and guided about the Garden by their own instructors (who had had a previous meeting and tour of the Garden in preparation) and by our own staff. They were given a typewritten questionnaire which they were asked to answer. Finally they all assembled in the auditorium and listened to 10 minute talks from several curators setting forth briefly some =. of the scientific work the Garden is doing. FLOWER Days Two flower days were observed in 1940. The Thirteenth An- nual Rose Garden Day ceremonies were held on Tuesday, June 11, beginning at 3:30 pm. Mr. E. A. Piester, who has charge of the Klizabeth Park Rose Garden at Hartford, Conn., and who is also a trustee of the American Rose Society, spoke on * Rose Culture in the Eastern United States,” chrome slides. About 250 members of the Garden and guests were his address being illustrated with koda- present. For the Fall Rose Garden Day members of the Garden and guests were invited to meet at 3:30 p.m., Tuesday, October 8, for inspection of the roses and for an informal discussion with Mr. Montague Free, Horticulturist, and Mr. S. R. Tilley, Rose Grower. A generous downpour emphatically vetoed all those preparations. Instead, Mr. Free gave an informal talk in the Laboratory Build- ing to the few hardy souls who ventured forth, his subject being “ New Roses.” Mr. Tilley also answered questions. Samples for demonstration had been freshly cut from plants in the Rose Garden. For these two events, as well as for Spring Inspection, May 14, tea was served in the rotunda; and for the social part of the occa- sions the Garden was, as usual, favored with the loyal and ef- ficient services of the Woman’s Auxiliary. We are glad to have this opportunity of expressing our appreciation of the splendid work of this organization. In this connection we might add that on June 13, at 4:30 p.m., the Garden gave an informal tea in honor of Mr. and Mrs. George T. Hastings and Prof. and Mrs. Edmund W. Sinnott, who were about to leave the City permanently. Mr. Hastings was retiring after having been head of the biology department in the Theodore Fic. 7. “Fern Palm” (Cycas circinalis). Young Pistillate Inflorescence.

Both had been prominently identified with the Torrey Botanical Club, under whose joint aus- vices with the Botanic Garden the tea was given. The affair ended — with a tour of inspection of the Rose Garden, PUBLICITY During the year this department prepared and sent to the chief papers of the metropolitan area and to horticultural magazines 47 news releases, totalling 65 typewritten pages of folio letterhead size, telling of events at the Garden—flowers in bloom, courses, lectures, botanical exploration, and research. Through our clipping bureau we received 813 newspaper clippings. seginning April 17, through the cooperation of Mr. Leonard H. Calvert, Educational Director of the Central Branch of the 3rooklyn Y. M. C. A., we showed in the Long Island R. R. sta- tion, a series of 30 slides of the Brooklyn Botanic Garden planta- tions, conservatories, and outdoor classes of instruction, inter- spersed with slides inviting the public to join the Garden. A set of these slides alternated with a set descriptive of the Y. M. C. A, and its work. These two sets were shown continuously by an ay, for about two —_— panel fda electrically operated projector, night and « months. Since the machine in which they were shown was sta- near the gates used by train passengers, these beautifully eaey tionec colored slides of the Garden must have been seen by thousands of persons, As usual, we prepared and mailed schedules of the broadcasts made by the Garden staff, January to June, and June to December ; also, schedules of spring and fall classes, mailed in March and September respectively. The spring circulars were printed in ad- yution at the Inter- —_— coca! vance so that they might be available for distri national Flower Show. Announcements of two early spring courses for amateur gar- deners, conducted by Miss Shaw and Miss Dorward, were prepared and mailed early in February ; and early in March, announcements of 3 lectures by Dr. Alfred Gundersen on “ Plant and Animal Evolution.” 109 Lists of lecture and docentry subjects offered by this department to the high schools were mailed to the biology departments in all New York High Schools and Annexes. PERSONNEL ITEMS Mrs. Virginia D. C. Horton, M.A., of Texas A. and M. College, came to us through the Bureau of Appointments at Columbia Uni- versity and assisted in teaching, docentry, and stenography from April 11 until June 13. Miss Hester M. Rusk, instructor in this department, revised the much-called-for Leaflet, “ Care of Cut Flowers,’ in December. In addition she has arranged a new loan set of lan- "and it was issued tern slides for the schools—“ Summer Wild Flowers,” and has begun to assemble one on “ Ferns.” We are also working on a set illustrating “ Conservation of the Soil” and in this the Soil Con- servation Service of the U. S. D. A. is giving us much assistance. From June 16 through July 14, Miss Rusk assisted me in pollina- tion, labelling, and mapping work on our chestnut plantation at Hamden, Conn. She has continued compiling data for a catalog of the plants of Long Island, and has served on the Local Flora Com- mittee of the Torrey Botanical Club. She also continued to serve as Librarian of the American Fern Society.

In January I was elected a member of the Advisory Board of the School Nature League of New York City. I continued to act as examiner for merit badges for the Brooklyn Council of the Boy Scout Founda- tion of Greater New York. MiIscELLANEOUS ITEMS The “ Exhibit of the Week,” calling attention to some feature of especial interest on the grounds or in the conservatories, was continued. The following new “ exhibits’ were added this fall: Callicarpa japonica, Lonicera japonica, Crataegus Lavallei, 110 The “ Forsythia-for-Brooklyn ” movement, of which Mrs. [d- ward ©. Blum is chairman, received our whole-hearted support. This department cooperated by issuing news releases and making arrangements with the newspapers for photographs of the plantings of Forsythia on the grounds. The Committee on Prizes and Scholarships, of Brooklyn College, awarded to Miss Marjorie Blaustein the Brooklyn Botanic Garden Scholarship for the spring term of 1940, and to Mr. Eugene Rosen- blu the same scholarship for the fall term. Both of the recipients of this scholarship elected our course in Trees and Shrubs. Mr. Hyman Sindel, teacher-in-training at Manual Training [1.S., and a graduate student at Brooklyn College, the recipient of the Rutherford Platt scholarship, elected the laboratory course. in flowering plants and ferns with Miss Rusk. Throughout the year docentry was carried on for garden clubs, and other associations or classes, such as the Reconciliation Trips, Inc., the nurses-in-training from Hackensack Hospital, the Torrey Botanical Club, St. John’s College of Pharmacy, Yosian Natural- ists, to mention only a few of these organizations. Mr. Rutherford Platt, of Platt-Forbes, New York City, a former student in our courses, gave us a lecture on March 16 on spring and summer flowers, entitled “ Preview of Spring.” The lecture was lustrated by Mr, Platt’s beautiful kodachrome slides. About 100 3rooklyn Botanic Garden “ alumni cm) ta attended. Mr. Platt, a for- mer student in our courses, has lectured at several centers and declares that he derived his inspiration from his studies with us. “ Posteard Bulletins were mailed to members of the Garden (1) on April 29, telling of the display of daffodils and mag- nolias; (2) on May 20, telling of the tulips in flower; (3) on May 22, announcing the distribution of surplus plant propaga- tion material; and (4) on October 30, calling attention to the brillant fall coloring of the P — cuonymus hedge in the Laboratory aza, and to the display of chrysanthemums. a To enlarge our collection of living drug plants, we have corre- sponded with the Puerto Rico Agricultural Experimental Station at Mayaguez, Puerto Rico. This station has already sent us seeds of Cinchona suecirubra, one of the species which yields quinine ; and of Guaiacunm officinale, the Lignum-Vitae, which yields the — 111 resin Of Guaiac. These seeds have been planted in the propagating house. Bureau of Information—As usual, we have received many re- quests for information and assistance, by mail, by telephone, and in person. The time consumed in complying with these requests represents a considerable share of all our working days—far more than this brief note would seem to indicate.

REO ROR ite OU RAnK®R OB ELE VEE NAR y INSTRUCTION FOR 1940 To THE Director: [ hereby present my annual report for the Department of FEle- mentary Instruction for the year 1940. Referring to my report of last year, the class of W.P.A. ex- cursion teachers mentioned as being trained in December 1939, not alone in knowledge of our economic greenhouse material and of our grounds, but in educational principles and pedagogy, con- tinued through January 1940, and for part of the spring. The Department felt this was a real contribution to W.P.A. educational work. These same young teachers, in the spring and fall, con- ducted classes around our grounds and through the greenhouses. These were classes coming to both the Botanic Garden and the Brooklyn Museum. Figures for attendance at our visiting classes and lectures appear in the report of the Curator of Public Instruction. It might be pertinent here to state that, while in the year of 1940 the attendance in visiting classes was slightly lower than in the preceding year, the number of sessions has been greater. This means, of course, that smaller groups have been taken, and some figures have been reduced because of the W.P.A. excursion teachers taking classes that otherwise would have been entirely in our hands, but because of their help and assistance, have been ours only in part. All the formal teaching scheduled by the Department of Elementary In- 112 struction is done by experienced people, members of our: staff. The number of lectures given to classes in 1940 was 814. A great deal of study material has been given out during this past year, due to the continuous work of Miss Hammond during one month of the summer and in odd moments throughout the year. This material goes to public school nature rooms and is used throughout the entire school with class after class. Nine thou- sand seventy-three teachers were supplied with such material, for the instruction of more than 300,000 pupils. The distribution of seeds to schools (more than 975,000 packets ) was slightly higher in 1940. More plants left our greenhouses this year than during | Over 200 regular classes, with a total attendance of more than 5,000, worked in the greenhouses. In these groups over 40,000 plants were raised. This figure represents work done by both It might be of interest to know that ast year. ~ ean children and grown people. practically all our stock material is raised here. A few flats of fern seedlings were bought this year, but that is all. A new addi- tion to our greenhouses put up in 1939 was hoped to solve the problem of overcrowded greenhouses. This it did only in a slight measure since, in the spring, the entire new addition was filled with seedling plants raised by the children for the outdoor garden. Another greenhouse or lean-to of similar size is needed to harden off the seedlings raised in our adult classes. Besides the professional training we gave to the W.P.A. ex- cursion and nature teachers, we also took for training, in the spring, Mr. John Campbell of the National Recreation Associa- tion, and during the summer, Miss Anita Appel, a student of Hood Each season the Department extends service in this way. en. College. Both of these people received training in the Children’s Gare Our Children’s Garden project was carried on as usual, and the work of the season was unusually successful. The garden donated EF respectively. This changing of call numbers on the pire cards is still in progress. Class 800 was reclassified, thus leaving only class 900 and the Children’s Club Room Library to be re- classified. Additional shelving was also installed against the wall of the reading room balcony. Four wooden bookcases, each of twelve shelves capacity, provide for expansion in the serials collection. The volumes purchased in 1939 with the money given by the Mrs. Field’s Literary Club were on display April 11th when the members of the Club were entertained at a tea given by the Li- brary Committee of the Woman’s Auxiliary of the Garden. iis exhibit was repeated on April 25th for the meeting of the Woman's Auxiliary and for the Spring Inspection in May. From October 15th to December 4th the library had a display commemorating the centennial of the death of the well-known American botanist, Rafinesque (1783-1840). Portraits, biographies, and works by Rafinesque were exhibited in the rotunda.

INTRODUCTION More than twenty species of lilacs grow in Eastern Asia, two in Teurope. ture. = CO plant “queue de Regnard There is no known reference to lilacs in ancient litera- It is thought by some that the lilac was first brought to the attention of Europeans by Pierre Belon du Mans (1554) who, in his Observations (p. 308 verso), describes a shrub with violet 19] ored flowers in inflorescences so long that the Turks called the ” Clusius (Rariorum aliquot stirpann, 192 1576, p. 126-7) identified Belon’s “queue de Regnard” as the lilac. Some eleven years prior to Clusius, Mattiolus, in his Commentarii (Sth Ed., 1565) illustrated a plant which he called “lilac,” but this illustration would appear to be based in part, as noted by Mrs. McKelvey, upon imagination, for it figures flowers (like the lilac) and fruits on the same inflorescence at the same time. In his 1598 edition (p. 854) Mattiolus gives a more accurate picture of the lilac as we know it. Linnaeus, in 1753, included two species in his “Species Plan- tarum’”: Syringa vulgaris and S. persica. Tn 1792 the Chinese spe- cies, Syringa villosa, was described; in 1830 the Hungarian lilac, S. Josikaea; in 1857, S. amurensis and S. pekinensis. Wkehder, in his “Manual,” 1940 edition, includes twenty-three species. Fig- ures 1 and 4 illustrate lilac species. The hybrid between S. vulgaris and S. persica (S. chinensis or Rouen Lilac) was known before 1800. S. Henry (S. villosa Josikaea), usually called S. Josikaea var. Lutéce, is illustrated in hg. 4. The Giraldii hybrids, or Early Tall Hybrids, illustrated in hg. 5, are of more rapid growth than the S. vulgaris varieties. Some of the species-hybrids and their varieties are among the most ornamental of lilacs. ‘arieties of the common lilac, resulting from artificial hybridiza- tion, are in general more showy than the species. Macrostachya was introduced as early as 1844. Most of the varieties have been produced by the famous French horticulturists, Victor Lemoine and his son Emile, beginning with the variety Jacques Callot, in 1876. The history of the varieties has recently been sketched by John C. Wister. (Nat. Hort. Mag. 20: No. 2. 1941.) Some clusters are very large, such as Réaumur, Mme F. Morel, and Président Poincaré; small clusters characterize Virginité, Arthur Wm. Paul, Emil Liebig, and others. In some varieties, such as Waldeck-Rousseau, the individual flowers are well sepa- rated; in others, such as Charles Sargent, they grow closely to- gether. But in most varieties the inflorescence is, to some extent, separated into sub-clusters, Flower forms of varieties are shown in fig. 2, as follows: Vesuve, cucullate or hooded petals. Catinat, petals narrower, bending back- ward. Virginité, narrow petals in center. Linné, petals narrow, 193 pointed. Président Carnot, corolla double. Président Poincaré, corolla triple. Montaigne, hose-in-hose, or corolla tube double. Victor Lemoine, flower globular. Charles Sargent, petals large, twisted.

Tue Opor or LILacs The odor of plants is due to essential oils, which are waste prod- ucts of their life-processes. The combination of these oils in flowers is called atfar, a word familiar to all in “attar of roses,” the oil distilled from the petals of roses, chiefly the Damask rose. — Attar is more complex, chemically, than the essential oils in odor- ous leaves, and this explains why the odor of flowers is more deli- 194 cate than that of leaves. For example, the odor of the leaves of a Rose Geranium is due to geraniol, but the more delicate odor of rose 1s due to geraniol plus seven or eight other volatile oils whose odors combine to give the more delicate scent of the flower. The essential oils of flowers occur in the epidermal cells of the petals and/or sepals, usually on the upper surface. In the flower- bud it is stored in an inert form—probably as a glucoside (a com- bination of sugar and an essential oil). As the flower opens this glucoside is acted on by an ensyme (ferment), which breaks down the glucoside and releases the essential oil, thus giving the opening ee its odor, The combination of essential oils in lilac flowers has a very for- Indding name—‘‘thre e-methyl-valeraldchyde -Isopropyl carbinol, with small amounts of phenyl acetaldehyde, phenyl propylaldehyde, and phenyl glycol.” But this forbidding name describes the chemical basis, as we all know, of a very atractive and popular odor, although the odor of lilacs is not attractive to some people. Some varieties of lilac have flowers with an odor unpleasant to most people, often resembling the disagreeable odor of the flowers of Privet, another shrub of the same family (the Olive Family) to which the Lilac belongs. (C.. The essential oil of lilac is not available as a perfume in com- merce. “A basic formula for a synthetic lilac oil would consist of approximately fifty parts of Terpineol, twenty-five parts of Hy- droxy Citronellol, six parts of oe Aldehyde, fv e parts of Helio- tropine, one part of Iso Eugenol, two parts of Alpha Amyl Cin- namic Aldehyde, twelve parts of DiMethy! Benzyl Carbinol, two parts of Phenyl Acetaldehyde, two parts of Anis Alcohol. Besides these, compound oils of Jasmine, Tuberose, Jonquil, Rose, Iris, Orange blossoms, Ylang, Hyacinth, and others, are added in small (Dr. Ernst Ohlsson. In personal letter.) quantities.’ LILAac Coors Mrs. McKelvey (1928) gives detailed descriptions of the colors of buds, and of the inside and outside of the flowers of several hundred varieties, according to Ridgway’s Color Chart. 195 Wister (1930) uses seven color groups: Violet Pinkish Lilac Blue Magenta Lilac Bluish Lilac Purple Lilac Mrs. Harding (1933), two groups: — Blue, Bluish Lavender, and Purple Pink, Red, and Wine colors Notcutt (1936), eight groups: Dark Vinous Red Carmine Dark Purple Bluish Mauve Mauve Pinkish Mauve Lilac Pale Thirion, have bright red buds, con- As the bud opens the color spreads A few varieties, such as Paul trasting with the paler flowers. The outside of the flower is usually more reddish, the and fades. The colors are best when about a third of the inside more bluish. inflorescence is still in bud. Several varieties have corollas with lighter margins, giving a mottled effect to clusters; others have streaks, light or dark. But the colored lilacs nearly all have more or less “lilac” color. In the present publication the lilacs are arranged in eighteen eroups, approximately similar to their arrangement in our collec- tion. The species form Groups 1-4; hybrids of species, Groups 5 and 6.

Villos 2 CULTIVATION AND PROPAGATION OF LILACS By MonraAGUE FREE SoIL Tt would seem that practically every authority on lilac culture, and every writer on the subject (including this one), makes a state- ment to the effect that lilacs prefer a rich, well-drained loam. Such assertions, however, should not deter anyone from planting lilacs even though his soil is not first class. As a matter of fact, some of the best flowering lilacs I have ever seen were growing in soil which would be considered well below the average in fertility. While lilacs are fairly tolerant so far as soil acidity 1s concerned there is — ittle doubt that they prefer one well supplied with lime. I remember the late Leonard Barron, whose capabilities as a grower were fully equal to his fame as a garden writer and editor, telling me that if lilacs failed to do well one should at once suspect soil acidity and apply lime freely, far beyond the usual amount. In preparing the soil for planting it should, if poor, be dug up to a depth of eighteen inches over an area of at least one square yard and have mixed with it a three-inch layer of rotted manure and one-half pound of bonemeal. If manure is not available use leaf- mold or sedge peat. Acid peatmoss may be used if it is neutralized by mixing one-half pound of pulverized limestone with each bushel. TIME OF PLANTING Lilacs can be planted at any season, but the best time 1s when they are dormant in fall or spring, provided that the ground 1s workable—not frozen and not too wet. Here in the Brooklyn Botanic Garden we prefer to plant them in the fall because at that time the soil is usually friable, moist, and in an ideal condition for 214 planting. Furthermore, in the fall there is not that hectic rush of work that occurs in the spring; and, in consequence, it is possible to do the job with the thoroughness that is so desirable. Lilacs start into growth very early, often when the soil is still muddy and therefore unfit for planting. If planting is deferred until the soil is ina suitable condition the shrubs may in the meantime have made considerable growth, and receive a slight check as a result of trans- planting. Fortunately, however, the root system of the lilac is hbrous and abundant and, because of this, planting may be effected without too much injury no matter whether it is done in fall or spring. The hole for the reception of the bush should be wide enough to receive the roots without crowding them and deep enough to allow the bush to be set an inch deeper than it was when growing in the nursery. Fine soil should be scattered between and over the roots and made firm by tramping with the feet. The surface should be slightly “dished” to facilitate watering, and a two-inch mulch of partially rotted manure or leaves spread over the area occupied by the roots. Lilacs transplant so readily that severe cutting back of young specimens to compensate for root injury is unnecessary, but it is a good plan at planting time to remove spindling and badly placed branches, and to shorten any shoots which spoil the symmetry of the bush, PRUNING The buds containing the inflorescences are formed in the fall to- wards the tips of the branches. It can readily be seen that any ex- tensive cutting back of the top during the dormant season must necessarily reduce the floral display the following spring assuming of course that the bush is sufficiently vigorous to produce flower- buds. | Therefore dormant pruning is usually restricted to the re- moval of dead wood, suckers, weak spindling wood, and insect- infested branches. Sometimes it may be considered desirable de- liberately to reduce the number of flower buds by thinning out crowded branches, thus improving the flower-clusters by throwing more strength into those remaining. ZAKS) Once severely—to within a foot of the ground if need be 1 a while it may become necessary to cut back bushes in order to achieve a desired purpose. For example, if a specimen has greatly exceeded the limits of height assigned to it, heavy pruning will bring it to earth; and similar treatment is accorded those bushes which have become scrawny, lopsided, or weakened by insect or —_— fungus attacks. It must be recognized, however, that such severe cutting back inevitably results in the loss of a crop of blooms for one year; and, by stimulating excessive vegetative growth, may so upset the plant’s balance that no flowers are produced for two or even three years. For these reasons a wise pruning program aims to avoid the necessity for drastic cuts by giving the bushes annual attention. Light pruning to promote symmetry can be done as soon as the flowers begin to fade and will do little to decrease flower production the following year. Cutting the flowering branches with long stems for interior decoration is a “killing-two-birds-with-one-stone” proc- ess in that it also is an effective means of preventing a too rapid increase in height. We are told that when the flower-clusters have faded they should be cut off to prevent seeds from forming and thus conserve the plant’s energies. It can easily be seen that the practice is worth while in the interests of tidiness and good looks, but it is doubtful whether it is an important conservation measure. Varieties vary greatly in the number of suckers produced; with some it is a constant battle to keep them from forming a thicket around the base of the bush. They may be cut off at any con- venient time, but it is well to leave a few as an insurance against the loss of the bush should the presence of borers in the main stems go unnoticed until irreparable damage has been done. Once in a while, say every two or three years, or whenever it seems desirable, one or more decrepit branches should be cut off close to the ground to allow strong suckers to take their place and thus rejuvenate the bush. PROPAGATION Lilacs may be increased by seeds, cuttings, suckers, layers, and by budding and grafting. 216 Seeds.—The preferred way of handling seeds is to gather them when mature and stratify them in moist sand in a cool place (about 40 degrees Fahrenheit) until February when they are sown in a If not convenient it is not necessary to greenhouse in sandy soil. dry in- go to this trouble, for seeds collected in the fall and stored doors at room temperature germinate without difficulty when sown That coddling is un- in greenhouse or coldframe in the s spring. lings from self-sown necessary 1s vouched for by the fact that seed seeds come up around the parent bushes provided the soil is not too assiduously cultivated, and weed growth is not too dense. In our Rose Garden, which adjoins the lilac collection, dozens of. lilac seedlings originate every year from seeds which germinate among the shoots of the roses where they are undisturbed by the hoe. Cuttings —Softwood cuttings taken two or three weeks after the flowers have faded—usually during the first or second week of June in the vicinity of Brooklyn—offer the easiest way of rooting lilacs from cuttings. Our prac- tice here is to insert the cuttings in sand kept constantly moist in a closed coldframe shaded by a double thick- ness of cheesecloth. Washed bank sanc ; _ is preferable as a rooting medium to aL milse cutting pre the mixture of peatmoss and_ sand pared for insertion, . ; ; which works so well with many kinds Ba of plants. The cutting should contain four or five nodes and the cut should be made just below the lowermost node and the pair o leaves immediately above it should be removed. Fig. 7. Cuttings inserted early in June should be well rooted by the end of July or beginning of August. Fig. 8. We find it desirable to rive them the protection of the coldframe during the first winter, planting them out the following spring. Lilacs can be rooted by means of hardwood cuttings but it is an The cuttings, consisting of uncertain method with most varieties. gathered in the wood formed the preceding growing season, are autumn after the leaves have fallen. They are cut into lengths of six to eight inches and tied in bundles of about fifty, butts even, ZA? and all pointing in one direction. The bundles are buried hori- zontally in moist sand, peatmoss, or sawdust, and stored in a temperature of 35 to 40 degrees. In the spring the cuttings should have callused and are taken out of storage and planted in sandy soil with only an inch or two of their tips showing above the surface. { i)<—node Internode—?

Root Cuttings —The statement has been made in print that lilacs can be propagated by root cuttings practically always with success. While not going so far as to say that this is not so, our limited ex- perience has been to the contrary. For example, on May 15th about twenty root cuttings (two to three inches long, of pencil 218 thickness or a little smaller) were buried one inch deep in a flat of sand. About thirty cuttings of the underground portions o suckers (stems) of similar size were set inthe other half of the flat. When ex- amined on June 9th about half of the root cuttings were dead, the remainder had made some callus tissue, but there were no signs of new root or shoot growth. On the other hand all the cut- tings of underground stems were alive, twenty eight out of thirty had started to Fic. 9 Cutting of a erow, and about half had new roots and portion of sucker show- shoots comparable to those shown in Fig. ere, eee eae Syringa Josikaea similarly propa- shoots, 4 : ; ty, : A gated is shown in Fig. 10. However all of this is probably of academic inter- est only, because the plants raised by this method grow too slowly to in- terest nurserymen; while amateurs, Pa who usually need only a few plants, will find it more convenient. to dig up entire suckers to increase their | stock. c Suckers.—These are branches which are given off below the surface of the soil, They may develop horizontally for a short distance but finally grow erect and produce leafy shoots above and roots below. On lilacs they usu- ally occur in profusion and, if the lilac is known to be on its own roots, may be dug up for propagative purposes in the spring or fall, when dormant. Tf the named variety was grafted on a seedling lilac the use of suckers might result in the propagation of the un- derstock rather than the variety de- Fre. 10. \ Cutting of a portion of sired, sucker (Syringa Jostkaeca). 219 Layers—The propagation of lilacs by layering affords perhaps the easiest and surest method for the novice. It is done by select- ing a branch or branches which can easily be bent to the ground. sranch one to two feet from its tip. The branch A slit is cut in the Fic. 11. Method of layering. The slit in the branch may be held open by a piece of grit. is then bent to the ground and the slit portion is buried in a trench two inches deep. The layer may be held in place by a heavy stone or by a forked stick (Fig. 11). When the layered portion is well rooted it may be severed from its parent, dug up, and planted separately. 220 Budding and Grafting.—It is a conmmon practice among nursery- men to bud or graft lilacs on roots, plants, or cuttings of privet-—— partly because it results in a salable plant in a shorter time. Some- times the growth of lilac the first year following its graftage upon privet is almost phenomenal. In my back yard the variety Lamartine, budded in August at ground level on a young privet bush, had by the fall of the following year attained a height of five feet. The objection to privet as an f understock is that lilacs grafted on HT it sometimes suffer from a disease known as graft-blight (See p. 224). However, this defect can be over- come without too much difficulty by proper handling by the nurseryman to ensure that the lilac ultimately forms its own root system and chokes out that of the privet.

Investigation (p. 237) Any course may be withdrawn when less than ten persons apply for registration and no course will be given for less than six per- sons. Since registration in many of the courses is restricted to a fixed number on account of the limited space available in the green- houses, and for other reasons, those desiring to attend are urged to send in their applications for enrollment, with entrance fees, to the Secretary, Brooklyn Botanic Garden, several days in advance of the first meeting. This avoids delay at the beginning of the first session, ensures a place in the course, and enables the instructor to provide adequate material for the class. Enrollment.—Persons are requested not to register in any course unless they are reasonably confident that they can attend the sessions of the class regularly and throughout. This is espe- cially important where the number to be enrolled is limited. To 228 register and not attend may deprive someone else of the privilege of attending. No registrations will be accepted for separate class sessions. Equipment available for the courses: Three classrooms, two laboratory rooms, and three Instructional Greenhouses ; the Children’s Garden, occupying about *4 of an acre fo, and divided into plots for the instruction of 200 children in gar- dening; at the north end of the Children’s Garden, the Children’s Building, for conferences, and for the storage of tools, seeds, spe- cial collections, ete.; the Auditorium, on the ground floor, capable of seating 570 persons, and equipped with a motion-picture machine and stereopticon, and electric current, gas, and running water for experiments connected with lectures. ' In addition to these accommodations, the dried plant specimens paeet in the herbarium, the living plants in the conservatories, and the plantations with about twenty types of gardens, are readily acces- sible. The main library and children’s library, which contain a mprehensive collection of publications on every phase of gar- dening and plant life, may be consulted freely at any time. A. Courses for Members and the General Public Although the following courses are designed especially for Members of the Botanic Garden, they are open (unless otherwise specified) to any one who has a general interest in plants. ‘Teach- ers are welcome. Starred courses (*) are open also for credit to students of Long Island University, and are described in the cur- rent Long Island University catalog. In harmony with an agree- ment entered into in the spring of 1935, the Botanic Garden, upon recommendation of the Chairman of the Biology Department of Long Island University, offers a course scholarship to one student of the University. Unless otherwise specified, all “ A” courses are free to mem- bers,f but the individual class meetings are open only to those who register for the entire course. Of others a fee is required, as in- dicated. In courses where plants are raised or collected, these become the property of the class members. + For information concerning membership in the Brooklyn Botanic Garden consult pages 1-ill. 229 FALL CouRSES Al. Plants in the Home: How to Grow Them.—Five talks with demonstrations. This course deals with the principles to be followed in raising plants, and in maintaining them in a healthy, vigorous condition in the home.

WEE LOCAL, SGhOOLS The Brooklyn Botanic Garden aims to cooperate in every prac- ticable way with the public and private schools of Greater New York in all matters pertaining to the study of plants and closely related subjects. The purpose of the Garden in this connection is to supplement and enrich the school work in the way of instruc- tion, demonstration methods, study material, ete., which otherwise would not be available. Geography classes, as well as classes in nature study and botany, find the collection of useful plants in the I¢conomic Plant Ilouse, the Local Flora Section, the Japanese Garden, the Herb Garden, and also the Meridian Panel, the Armillary Sphere, and the La- beled Glacial Boulders, valuable adjuncts to their class work. Ar- rangements may be made by teachers of geography to have their classes study these features under guidance. IHlustrated lectures at the Garden for geography classes may also be arranged. To visiting college classes in geology and physiography the Bo- tanic Garden offers interesting material for a study of glaciation. Notable features are a portion of the Harbor Hill terminal moraine (Boulder Hill), the morainal pond (the “ Lake’’), the labelled pst 239 glacial boulders, and the Flatbush outwash plain. See Guide No. 7,“ The Story of our Boulders: Glacial Geology of the Brooklyn Botanic Garden.” Talks at Elementary Schools.—The principals of public or private elementary schools may arrange to have talks given at the schools on various topics related to plant life, such as school gar- dens and garden work with children, tree planting, the conservation of wild flowers, Arbor Day, ete. If an illustrated lecture is de- sired, the lantern and operator must be provided by the school, but slides will be furnished by the Botanic Garden. Address the Curator of Elementary Instruction for appointments. Talks at Secondary Schools and Colleges.—Informal illus- trated talks on various subjects of an advanced botanical nature are always gladly given at Secondary Schools and Colleges by members of the staff. Arrangements for such ta made with the Curator of Public Instruction. — ks should be School Classes at the Garden.—Public or. private schools, both elementary and secondary, may arrange for classes to come to the Botanic Garden for illustrated lectures by a member of the Garden staff, or for guided tours of instruction through the conservatories and outdoor plantations. Such lectures, conserva- tory trips, and outdoor trips are planned for correlation with the New York City school syllabi in nature study, biology, and geography. Visiting classes must be accompanied by their teachers, and notice of such visits should be sent at least one week in advance. Blank forms for this purpose are provided by the Garden. Lists of talks and trips offered will be sent on request: for Junior High and Elementary Schools address the Curator of Elementary In- struction, for High Schools, the Curator of Public Instruction. The Garden equipment, including plant material, lecture rooms, lantern, and slides, is at the disposal of teachers who desire to instruct their own classes at the Garden. Arrangements must be made in advance, so that such work will not conflict with other classes and lectures. For High School and College classes address the Curator of Public Instruction. For Junior High and Ele- 240 mentary School classes address the Curator of Elementary In- struction, The principal of any Elementary or High School in Brooklyn may arrange also for a series of six lessons on plant culture to be given to a class during the fall or spring. A small fee is charged to cover the cost of the materials used. The plants raised become the property of the pupils. The lessons are adapted for pupils above the third grade. Seeds for School and Home Planting.—Penny packets of flower and vegetable seeds are put up by the Botanic Garden for children’s use. In the early spring, lists of these seeds, order blanks for teachers and pupils, and other information may be secured on application to the Curator of Elementary Instruction. Demonstration Experiments.—Teachers may arrange to have various physiological experiments or demonstrations con- ducted at the Garden for the benefit of their classes. Communica- tions in regard to these matters should be addressed to the Curator of Public Instruction, Loan Sets of Lantern Slides.—Sets of lantern slides have been prepared for loan to the schools. Each set is accompanied by a short lecture text of explanatory nature. In all cases these sets must be called for by a responsible school messenger and re- turned promptly in good condition. Address, by mail or tele- phone, Mr. Frank Stoll, custodian. The subjects now available are as follows. Other sets are in preparation. 1. Plant Life 6. Spring Wild Flowers 2. Common Trees 7. Summer Wild Flowers 3. Forestry 8. Fall Wild Flowers 4. Soil Conservation 9. Ferns and Fern Allies 5 . Conservation of Native Plants Study and Loan Material for Elementary Schools.—1’o the extent of its facilities, the Botanic Garden will provide, on request, various plants and materials for nature study. As far as pos- sible this material will continue to be supplied gratis to elementary schools. Requests from [Elementary Schools should be made to 241 Miss Elsie T. Hammond, and material should be called for at the Information Booth on the ground floor. Special Work for the Blind.—Short courses of two or three lessons will be given to blind children of elementary and junior high school age. ‘The work will be both in the greenhouses and on the grounds, supplemented by special opportunities for handling living materials in order to acquaint the children with the world about them. This series will be given free of charge to classes of not more than 15 children and not less than 7. The work will be offered on school days to supplement and enrich regular class- work. Study and Loan Material for Colleges, High Schools, and Junior High Schools Available at the Brooklyn Botanic Garden, 1941-1942 The Botanic Garden is able to supply various plants and plant parts for study; certain protozoa ; sterilized nutrient agar; and also material and mounts for exhibit purposes. When containers are necessary, as in the case of agar, algae, and protozoa, they must be furnished by the school. In the past, the Garden has offered this service gratis, but both on account of the increasing demand and because of the decrease in appropriations, it has become necessary to make a small charge for the material supplied or loaned. A Price List of the various materials furnished will be mailed on request. Requests should be made by mail or telephone (Main 2-4433), at least one day in advance, to Miss Jeanne P. Walther, and the material should be called for at Room 204. Unpotted material will be mailed if the school pays postage. Livinc MATrERIAL—PLANTS Algae: Spirogyra, fresh, and preserved conjugating.

This service is free of charge to members and accompanying friends; to others there is a charge of 50 cents per person. For information concerning membership in the Botanic Garden see pages 1-111 of this Prospectus. EXTRA-MURAL LECTURES jer With the exception of talks to schools, the Botanic Garden does not officially schedule members of its personnel for lectures or talks outside the Botanic Garden, except for lectures on the Garden itself or some aspect of its work. In such cases no fee is charged beyond traveling expenses. Several members of the personnel are available for lectures to garden clubs and other organizations on topics of general horti- cultural or botanical interest. A list of lecturers, with lecture topics and the fee charged, may be had by addressing the Curator of Public Instruction. Arrangements are to be made directly with the lecturer concerned. See page i for special privileges to Member Clubs. MEETINGS OF OUTSIDE ORGANIZATIONS The Brooklyn Botanic Garden is glad to welcome outside or- ganizations wishing to hold meetings at the Garden, provided the general purpose of the organization 1s closely allied to that of the Botanic Garden (e.g., Botanical Groups, Garden Clubs, Nature Study Clubs, Conservation Organizations, etc.), or that the specific purpose of the meeting 1s of mutual interest and advantage to the organization and the Botanic Garden. Meetings must always be arranged for in advance. A folder giving full details, and an appheation blank may be had by addressing The Custodian, INDEX TO VOLUME XXX pues uae 47 s Given by the Personne! open res, 157 Activities, 1940, Addresses, and ‘Pay Botanic Garden 1940, Talks toe Agreement Bet the Brooklyn ‘Botanic G ae er the American Fern Society Concerning the Depo- sition of the Herbarium of the Fern Society at the Botanic Gar- den, American Gardens American ‘Fern Journal, 36 ppel, Anit Art, The eases Museum of, Association of Botanical 1 Articles, Newspaper, 48 Tec si cal and Popular, a Grace Te ok Attendance 52, 101, 102 the Conservatories 102 Ate ae At ee We oman’s, 66, 174 penearey Ralph C., 60, 67, 100, 138 Helen E., 70 Bee to the Brooklyn Garden, Forms of, ca and Tree Club, 7 ye New York, Botanic Biren George, 68 Blaustein, Marjorie, 59, Special Work a ae 241 Blum, Edw ag Blum, Mrs. Edw var Td-Gs, 110 Board of E een gone 60 3oard of sae oe 59 Bonta, B eee Borer C Cy eee ae 3 eae Gardens and pela ae American pesos on of, 61 "L. 62 cas 49 Bee Botanic Garden Collection, Lilacs in Brooklyn Bureau of Charities, 63 Map of lilaes in the, 197 eee aeaeie ot pats and Sci- Offi 173 Bro ook Budget, Neus N.. ate Funds, Requests for erat Capital Outlay, 71 Tass, Buhle, ae Os Butler, Mrs. “Glentw orth R., 66 California ae ing Garden Show, 62 Campbell, Jol P62" 12 Charities, Brooklyn Bureau of, 63 Cheney, Ralph H., 100, 138 Chestnut Breeding a ork i in 1940, 87 Chestnut, Hybr Children’s Course oe Choate, Nathaniel, 64 Cinchona eee 110 ay, What the Garden Has Meant o the Civic Gonncil ‘he Brooklyn, 61 Classes, 117 and Lectures, 102 Clausen Robert T., 172 lub Me mberships, iv Caen Fund, 143 Ones Talks at Secondary Schools 239 Coniters ser rvatories, 102, 244 Cees 170 Se St 56 ith Local Schools, 238 aR Other institutions, 125 with Schools, Thirty Years, 41 Courses ot nstruction, 225, 227 Adult, 104 eeaue WW illiam G., 69 G[ager], 194 Cultivation and Lilacs, 2 Cycas varene Young Pistilate In- florescence, 107 Propagation of 247 sens Mrs. as 66 vidoff, Arthur an Martin, ey” del Valle, Rey, 64 Dieamiedons.
