GLASSMAN RESEARCH ASSOCIATE IN PALMS, FIELD MUSEUM OF NATURAL HISTORY UNIVERSITY OF ILLINOIS, CHICAGO CIRCLE As the revisional study of Syagrus progresses, new information accumulates. This work is a continuation of another article bearing the same title (Glassman, Fieldiana: Botany 31 : 363-397. 1968). Ex- amination of recent collections, especially, from the Bailey Hortor- ium and the U. S. National Herbarium plus my own collections from Brazil has revealed some interesting results. This research has been supported by N.S.F. grant no. GB-6899. One of the most perplexing problems in studying the genus Sya- grus has been the clear distinction between S. flexuosa (Mart.) Becc. and S. campestris (Mart.) Wendl. Both species were originally de- scribed by Martius in 1826 under the genus Cocos. Examination of the lectotypes of each taxon from Munich (figs. 1 and 2), both col- lected by Martius, reveals certain basic differences. In S. flexuosa the middle pinnae are up to 7 mm. wide with slightly oblique tips and the female flowers are 19-20 mm. long; whereas the middle pinnae are up to 13 mm. wide with strongly oblique tips, and the female flowers are only 15-17 mm. long in S. campestris. Study of other collections of these two taxa seemed to indicate that there were probably two entities based on size of female flowers, but differences in the width and the tips of the middle pinnae were not as evident. I attempted to use other key characters, such as size of spathes and size of spadix branches, but these, too, were unsatisfactory. It was not until recently, when I compared the habit (both frequently growing in clumps) and the geographic distribution of the two taxa (both have been reported from the states of Sao Paulo, Minas Gerais, Goyaz, Bahia, and Matto Grosso in Brazil), that I realized they may be conspecific. Further study revealed that the width and apices of the middle pinnae are very variable in some populations. In Glass- man & Gomes 8044 to 8051 (CHI) inclusive, collected in Lagoa Santa, Minas Gerais, the maximum width of the pinnae ranges from 5-10 mm. and the tips are largely oblique in younger leaves, whereas Library of Congress Catalog Card Number: 78-92472 11 FIG. 1.

In other collections, however, the mature leaves may have pinnae with either all symmetrical or all oblique tips on the same plant. In another example collected from the state of Goyaz, Glaziou 22261 (C, F, FI, G, K, MO, P, US), the pinnae vary from 5 mm. to 15 mm. wide in different specimens. Length of female flowers is also quite variable. Examples are Glaziou 22261, in which the flowers are 12-13, 17-18, 15-20, and 17- 20 mm. long on different spadix branches; and Glaziou 20026 (C,K), from Minas Gerais, the flowers being 15-17 and 17-20 mm. long. Cocos urbaniana Dammer, (Glaziou 15558 — P, holotype; C,F,FI, K,MO) undoubtedly belongs here, too (fig. 3). Type specimens resemble the lectotypes of both C. campestris and C. flexuosa. The pinnae are 8-11 mm. wide with strongly oblique tips and the female flowers are 13-17, 15-17, and 19-22 mm. long on different spadix branches. In view of the fact that C. campestris and C. flexuosa were both described by Martius in the same publication in the same year, the problem is which name to use. C. flexuosa was described on p. 120 and C. campestris on p. 121, therefore I am selecting C. flexuosa as the earlier name. Syagrus flexuosa (Mart.) Becc., L'Agric. Colon. 10: 466. 1916.

Colon. 10: 468. 1916. The following is an emended description of S. flexuosa, based on more than 50 numbers examined by me. Palm 2.0-4.5 m. tall, trunks frequently in clumps. Naked petiole up to 37 cm. long, sheathing base up to 31 cm. long, edges deterior- ating into separate fibers; rachis of leaf up to 106 cm. long, up to 79 pairs of pinnae, mostly in clusters of 3-4 (2-5), glaucous or eglaucous on both surfaces, middle ones up to 36 cm. or more long, 5-16 mm. wide, with oblique or acuminate tips; expanded part of spathe up to 48 cm. long and 6 cm. wide, branched part of spadix up to 44 cm. long, branches up to 18 or more in number, each branch up to 36 cm. long; male flowers 5-10 mm. long on upper part, 10-16 mm. long on lower part; female flowers 12-22 mm. long, 6-9 mm. wide; mature? 82 FIELDIANA: BOTANY, VOLUME 32 fruit 3.0-4.3 cm. long and 1.5-1.7 cm. in diameter, with beak up to 6 mm. long, endocarp cavity mostly regular in outline, endocarp 3-3.5 mm. thick; complete seed not seen. Another group of related species which present a problem in identification are Syagrus sancona Karsten and S. tessmannii Burret. S. sancona was originally described from Colombia in 1857, Karsten s.n. — LE, lectotype (fig. 4), and in 1866 Karsten also published an excellent illustration of this palm. Dahlgren (in Field Mus. Nat. Hist. Bot. 14 : 268. 1936) apparently assumed that Oreodoxa sancona H.B.K. and Syagrus sancona Karsten, both described from Colombia, were the same thing and made the following citation: Syagrus sancona (H.B.K.) Karsten. This is incorrect for S. sancona was described by Karsten as a new entity without any reference to the older H.B.K. name. Consequently, Karsten's name precludes the transfer of Oreo- doxa sancona H.B.K. to the genus Syagrus. There is no way of determining what Oreodoxa sancona is because the brief description is not characteristic of Syagrus and, furthermore, no illustrations were published nor could any type specimens be found. Therefore, I am designating Oreodoxa sancona H.B.K. as species incerta. In addition to this, Dahlgren listed Oenocarpus sancona (H.B.K.) Spren- gel as a synonym of Syagrus sancona Karsten. This, too, is incorrect because it is based on Oreodoxa sancona H.B.K. In 1943, Dugand (Caldasia 2 : 289.) followed Dahlgren's use of Oreodoxa sancona H.B.K. as a basionym of S. sancona Karsten. He also listed Oenocarpus iriartoides Triana as a synonym, saying that the description and type locality of Oreodoxa sancona H.B.K. is practically identical to this species. Here again, the description of 0. iriartoides is inade- quate to place it in Syagrus; and since no illustrations were published or could any type specimens be found, I am omitting this name from the synonymy of S. sancona Karsten. S. tessmannii Burret, on the other hand, was described from Peru in 1933. Holotype material, Tessmann 4811 (fig. 5), consisting of spathes, spadices, flowers, petiole, part of a leaf and a piece of wood, is located in the Berlin herbarium. Since one palm originated from Colombia and the other from Peru, I assumed all along that they were distinct taxa. But, after examining a number of specimens labelled S. sancona and S. tessmannii, I noticed a striking similarity in the texture of the female flowers which are strongly nerved or rugose in both species. Apparently, the only other species of Syagrus with strongly nerved female flowers is S. ecuadorensis Becc. (fig. 6), known exclusively from Ecuador and closely related to the two palms FIG. 4.

Eggers 15681 (K). 87 88 FIELDIANA: BOTANY, VOLUME 32 above, but these flowers are only 5-6 mm. long. Further study of the collections revealed that size (7-9 mm. long) and shape (obtuse tips) of the female flowers, and size (3.0-3.3 cm. X 1.5-2 cm.) and shape (ovoid and slightly beaked) of the fruit, and width of the middle pinnae (3.8-4.5 cm.) are very similar. The most variability, how- ever, seems to be in the shape and size of the male flowers. Flower size may vary from 8-9, 9-10, 10-11 or 9-12 mm. in length and are either lanceolate, ovate, or obovate in shape. Sometimes, all three shapes are found in male flowers of the same collection. An isotype (G) of S. tessmannii and a specimen collected from Colombia (Philip- son, Idrobo & Fernandez 1656-BM) contain separate detached spa- dix branches with male flowers only. Although Burret mentioned two kinds of spadices in his description, I was still doubtful about this characteristic because in the genus Syagrus male flowers are normally found in conjunction with female flowers, mostly on the lower half, and on the upper half of the same spadix branch the male flowers occur by themselves. A collection from Venezuela, Steyer- mark & Rabe 9651 P-BH (fig. 7), dispelled all doubt in my mind because it contains two kinds of partially complete spadices, a larger one with branches bearing both mature female and male flowers, 9-10 mm. long and 3-3.5 mm. wide; and a smaller one (immature?) with branches having mostly male flowers, 8-9 mm. long and 2- 2.5 mm. wide, and a few undeveloped female flowers. Corrected synonymy for this taxon is as follows: Syagrus sancona Karsten, Linnaea 28: 247. 1857; Fl. Colomb. 2: 147, t. 177. 1866. Cocos sancona (Karsten) Hooker, Report Kew 1882: 72. 1884. Syagrus tessmannii Burret, Fedde Rep. 32: 106. 1933. The following description is based on specimens examined and combines the characteristics of both S. sancona and S. tessmannii. Palm up to 20 m. tall, trunk up to 35 cm. in diam. at base. Naked petiole up to about 56 cm. long, sheathing base up to 79 cm. long; rachis of leaf up to 255 cm. long (310 cm., fide Burret), up to 163 pairs of pinnae, mostly in clusters of 2-4, middle ones 56-100 cm. long, 3.5-4.5 cm. wide, mostly with acuminate tips; expanded part of spathe up to 100 cm. long and 21 cm. wide; branched part of flowering spadix (with both male and female flowers) up to 76 cm. long, branches up to 138 in number, each up to 58 cm. long; male flowers 7.5-11 mm. long on upper part, 9-12 mm. long on lower part; female flowers mostly strongly nerved with blunt tips, 7-9 mm. GLASSMAN: SYAGRUS MART, II 89 long and 6-7 mm. wide; staminate spadix (immature? and with branches partly cut off) about 30 cm. long, branches about 25 or more in number, each branch (detached) up to 45 cm. long; male flowers 8-12 mm. long; branched part of fruiting spadix up to 109 cm. long, branches up to about 100 in number, each up to 63 cm. long; fruit 3.0-3.3 cm. long and 1.5-2 cm. in diameter, with short beak, endocarp cavity mostly regular in outline, trivittate, endocarp 1.5- 2 mm. thick; seed 1.5-1.7 cm. long and 0.8-1.0 cm. in diameter, cavity very narrow.

Another pair of poorly defined species is Syagrus orinocensis (Spruce) Burret, described from Colombia and S. Stenopetala Burret, from Venezuela. The type of S. orinocensis, Spruce 1+9 — K (fig. 8), consists of three separate leaf parts and some naked spadix branches; whereas type material of S. stenopetala, John 1208 — VEN, holotype; US, BH (fig. 9), is composed of separate leaf parts, spathes, and spadices with male and female flowers, and fruiting spathes and spadices with a few detached fruits. Even though both species were adequately described, neither one was accompanied by an illustra- tion. The types resemble each other in the pinnae being arranged in loose clusters of 2-3 and 2.0-2.4 cm. wide. Fruits of the type of S. stenopetala are unusual in that they are rather long (3.4-3.7 cm.) and relatively narrow (1.3-1.5 cm. in diameter) with a beak about 8 mm. long; and the female flowers are only 5 mm. long and 4 mm. >MM-n MM III < \ I l,| V MUtri - , 'I II » *io IMO..

Robe 96519 (BH). 90 CLASSMAN: SYAGRUS MART, II 91 wide. I am quite certain that both the fruits and female flowers of the type of S. stenopetala are immature or incompletely developed because in another collection from Venezuela, Pittier 9154 — VEN, US, G (fig. 10), determined by Burret as this species, the fruits are up to 3.4 cm. long and 2.2 cm. in diameter with a short beak, and the female flowers are 7-9 mm. long and 6-7 mm. wide. Another specimen, collected along the Rio Orinoco in Venezuela, e.g., Wur- dach & Monachino 40852 (BH), has mature fruits and female flowers approximately the same size and shape as above, and, in addition, young fruits (about 1.5 cm. long) with a beak about 5 mm. long, similar in shape to the fruits of Jahn 1208. Other specimens col- lected along the Rio Orinoco (L. Williams 13138, 16019— F; Wessels Boer 1873 — CHI) also have short beaked fruits which are about 3 cm. long and 2 cm. in diameter. Until evidence to the contrary can be found, I am reducing S. stenopetala to synonymy under S. orinocensis. The most closely related species to S. orinocensis seems to be S. allenii Classman, recently described from Colombia in Fieldi- ana: Bot. 31: 285. 1968, but the latter taxon has wider pinnae (up to 3.4 cm., rather than 2.0-3.0 cm.) smaller female flowers (6-7 mm., rather than 7-9 mm.) and smaller, more rounded fruits (2.5 cm. long and 2.2 cm. in diameter, rather than 3.0-3.4 cm. long and 2.0 - 2.2 cm. in diameter).

Originally, it was reported that most of the palm material at the Botanisches Museum in Berlin — Dahlem was destroyed during World War II. Later it was learned that a number of specimens were salvaged from the ruins and subsequently, I wrote Dr. Eva Potzal inquiring about specimens of Syagrus. I was delighted to learn that a sizeable number from this genus were saved and recently I received photographs of these palms. The following list is divided into three parts: 1. holotypes, 2. isotypes, and 3. other specimens. 1. HOLOTYPES Syagrus brachyrhyncha Burret (fig. 11). Brazil: Para, Rio May- curu, Kreis Monte Algre, Hubner 112. Specimen resembles S. cocoides Mart, very closely. S. pleioclada Burret. (fig. 12). Brazil: Minas Gerais, Serra do Cipo, June 1932, Werder- mann 3916. This is a very distinct species. Several collections have since been made by others including myself. S. tessmannii Burret. = S. sancona Karsten. Previously discussed in this article. Holotypes of Syagrus, originally deposited in Berlin and which are still missing include S. microphylla Burret (Werder- mann 3366) and S. werdermannii Burret (Werdermann 3472). The determination of these two species is doubtful since no other specimens have been seen. 2. ISOTYPES S. ecuadorensis Becc. (Eggers 15681). Specimens of this taxon also have been seen from the following herbaria: M, holotype; K,P,US. GLASSMAN: SYAGRUS MART, II 103 S. hoehnei Burret. (A. Gehrt 25.318— SP, holotype). A num- ber of other collections have been made of this distinctive species. 3. OTHER SPECIMENS The remaining specimens of Syagrus (about 69 numbers) are not important to the revisional study of the genus. Most of them were collected in botanical gardens and many of these are incomplete specimens, consisting only of fruits or portions of leaves.
