PALM.E. 519 



linear, somewhat distant ; exterior <? perigone 3-partite, half as long as the interior ; warts 

 of the epicarp depressed. — Pluken. Phytogr. t. 323. /. 3 : the fruit. The character of 

 the warts is taken from Plukenet's figure and Surinam-3pecimens. — M. saccifera, Mart, 

 (t. 98, 99), has entire, oblong leaves, almost truncate at the summit : their teeth are equal 

 to those of the upper part of our leaf, but their nerves are said to be twice as much distant 

 (1"). Our leaf (perhaps only the upper part of one) is almost 3' long, 2' broad, entire from 

 the summit to about the middle, with the midribs of the teeth 6'" distant from each other : 

 the lower part consists of obliquely adnate segments, 2-5 of them united into a cohering or 

 lacerate blade, rarely single, these blades or single segments distant from each other for 

 spaces often above 1" (" from the beginning," Or.). In the spadix and flowers no difference 

 from M. saccifera was observed, except in the $ perigone : its exterior leaflets roundish (1'" 

 diam.), much imbricated, shortly cohering at the truncate base, interior ovate-oblong (2'" 

 long), valvate. Conical spathe 1J' long, gradually acuminate (not poiutleted, as in Jacquin's 

 figure and specimens of M. saccifera) ; fruit 3-1-globose : each pyrena 2'" diam. — Hab. 

 Trinidad !, Cr., at Irais ; [Guiana !]. The fruit of Manicaria is often carried by currents to 

 the shores of Barbadoes {Pluken.) and Jamaica (SI.) : the latter is unknown to me ; and it is 

 to be established, to which species the Manicaria, existing at Carthagena and in Panama, 

 may belong. 



Tribe II. COCOINEJZ. — Fruit monopyrenous, 1-3 (-&)-celled -. putamen S(-Q)-porous. 

 — Leaves pinnatisect, rarely pinnatinerved-entire : segments reduplicate or flattish ; flowers 

 unisexual, usually monoecious in the same spadix ; albumen entire. 



12. DESMONCUS, Mart. 



Perigone exterior small, subtruncate or 3-dentate, interior $ 3-phyllous, $ urceolate, sub- 

 truncate. Stamens 6. Ovary. 3 (-1) -celled, with 2 cells abortive: no cupule of abortive 

 stamens : stigmas 3, terminal. Drupe 1-seeded : putamen 3-porous at the summit. — Stem 

 arundinaceous, scandent, prickly ; leaves scattered: rhachis produced into a cirrhose ex- 

 tremity, with its segments transformed into hooks : petiole sheathing : spadix simply 

 branched, axillary : flowers sessile ; drupes small. 



19. D. major, Cr. ms. (n. sp.). Leaf-segments 20-jugal, linear-acuminate, flattish, 

 partly clustered : rhachis prickly, covered with a blackish, deciduous tomentum : hooks stout, 

 6-jugal ; spathe covered with brown prickles. — Inferior leaf-segments 1' long, 5'" broad, un- 

 armed or with a few, distant prickles on the margin : hooks 3"-l" long, channelled-3-gonal 

 above the thickened transversely sulcate base : rhachis subterete below, with the upper side 

 flattish, 3-gonal above: its prickles slender, scattered, the longest 6'" long, most smaller; 

 spathe i', its prickles 3"'-4'" long. — Hab. Trinidad !, Cr., at Caroni. 



13. BACTRIS, Jacq. 



Perigone £ exterior 3-partite or 3-fid, rarely 3-phyllous, interior 3-phyllous; 9 exterior 

 and interior urceolate, subtruncate or 3-dentate. Stamens 6-" 12." Ovary 3(-l)-celled, 

 with 2 cells abortive : no 6-dentate cupule: stigmas 3, sessile. Drupe 1-seeded : putamen 

 laterally 3-porous. — Trunk usually prickly along the leaf-sheaths ; leaves often scattered, 

 but chiefly approximate above, pinnatisect, rarely 2-fld-entire ; spadix simply branched or 

 simple, axillary ; flowers sessile. 



Sect. 1 Eubactris. — (Syn. Sphserocarpee, Mart.). — Rhachis of the spadix produced. 



20. B. simplicifrons, Mart. Wholly devoid of prickles, except on the margin of 

 the leaf-summits ; trunk low (3'-6' high, the leaves included), arundinaceous : leaves 2-fid- 

 entire : divisions oblong, curved-acute, broadly adnate at the flat base, diverging in an acute 

 angle • spadix simple, short, nodding ; inner spathe as long, glabrescent ; drupe small, sub- 

 globose.— Mart. Palm. t. 73 C.flg. 1, 2.— Leaf-divisions 10"-12" long, 2i''-3" broad at 

 the middle and at the base : prickles black, setaceous, 2"'-3'" long: petiole 3"-6", spadix 

 l"-2" long, the latter shortly peduncled ; drupe " red," 3'" diam., with a truncate point. — 

 Hab. Trinidad !, Cr., at Irais ; [Venezuela 1, Guiana !, in moist woods; equat. Brazil].
