16. G. oxycarpa, Mart. "Trunk 4' high " (Mart) ; leaf-segments S-i-jugal adnate, 

 broadly oblong (or partly lacerate), obliquely acute, subequal, little distant ; spadix-branches 

 divided, subfastigiate, pubescent : spathes several (3" long) : flowers 4-5-seiiate, lax : lip of 

 the alveole shortly deltoid or subtruncate, entire ; exterior $ perigone two-thirds as long as 

 the interior : staminal tube short, half as long as the latter ; berry subglobose with a 

 bluntish broadly conical point (3'" long). — Leaves 3' long, 1' broad : segments 3V'-6" 

 broad, uppermost broadest; spadix loug-peduucled, 2'-2j', secondary branches 6" long. — 

 Hab. Trinidad!, Cr., at Irais ; [Haiti]. 



10. CALYPTRONOMA, Gr. 



Flowers and staminal tube of Geonoma. Anthers sagittate : cells cohering except at the 

 base. Ovary 3-celled, with 1-2 cells 1-ovulate, the rest abortive : style excentrical-termi- 

 nal. " Fruit subangular, 1-seeded." — " A high, unarmed tree ;" leaves equally pinnatisect : 

 pinna deeply reduplicate at the base, 2-fid at the top ; spadix equalling the inner, large, 

 rigid-leathery spathe : branches ^-partite-, divisions long, thickish, bearing flowers to their 

 base. 



This genus, constructed upon the Elceis occidentalis, Sw., is said to approach in habit 

 Euterpe, but in character is somewhat analogous to Calyptrogyne, Wendl., from which how- 

 ever it is much distinguished by habit, by the infundibular, exserted staminal tube, the 

 sagittate anthers (resembling those of Geonoma synanthera, Mart. t. 13), the structure of 

 the <j> flower, the divided spadix, and the basilar " 2-valved " spathe. Swartz's description as 

 far as it goes, is correct, except in the staminal tube, which he believed to be a corolla : 

 from what he says of the fruit, it may be conjectured, that Calyptronoma will be distinguished 

 from Geonoma in carpological characters. 



17. C. Swartzii, Gr. " Trunk 50'-60' high, smooth ; " leaf-segments linear- 

 acuminate, 2-fid ; spadix-branches divided : alveoles hexastichous : lip deltoid-roundish, 

 eutire ; staminal tube slender, shortly 6-fid. — Elseis occidentalis, Sw. (Geonoma, Kth.). 

 Euterpe sp., Pd. in Kew Museum. — The trunk, if confidence is to be put upon Sloane's and 

 P. Browne's synonyms, quoted by Swartz, would be " as thick as one's thigh, very hard, 

 somewhat crooked, with a great swelling at the root;" leaves " 5'-10' long: segments 

 2£'-2' long, 1£" broad at the flat middle, 2-fid to 4"-6"from the point, green, glabrous : 

 double basilar insertion-line 5'" broad; spadix 2-3' long, 1" thick atlthebase, dissolved 

 into a few primary branches : the secondary ones 6"-12" long, 2"'-3'" thick : alveoles 

 2"'-4'" distant in each longitudinal series ; inner spathe flattish, about 2" broad above, 

 externally smooth, dull-green, red within ; flowers ternate in most alveoles, half-cxserted, 2 

 lateral usually $ ,'central ^ ; perigonal leaflets of $ lanceolate-oblong, cartilaginous, brownish- 

 purple, the exterior 1'", the interior 2"' long : staminal tube 3'" long ; ? perigone about 1"' 

 long : cupule calyptrate : remaining lower part somewhat adhering to the inner perigone. 

 — Hab. Jamaica !, Pd., in the lower region of the interior hills ; Barbadoes? (SI.) ; [South- 

 eastern Cuba!, Wr. 1466]. 



Subtribe IV. MANICARIEJ2.— Fruit Z-\-pyrenous : putamen thick: each with a 

 single pore at the embryo-cavity. Leaves entire or pinnatisect: segments redupli- 

 cate. 



11. MANICARIA, G. 



Perigone exterior and interior 3-phyllous or exterior $ 3-partite. Stamens numerous, ru- 

 dimentary ones in ? . Ovary 3-celled : stigmas 3, sessile, terminal. Fruit dry, echinate- 

 verrucose, slightly 3-1-lobed : each putamen with a single, basilar pore. Albumen entire, 

 hollow. — Unarmed, arboreous palms ; leaves pinnatinerved, entire, or pinnatisect ; spadix 

 axillary, simply branched, pyramidal : spathe resembling a bonnet, dissolved into reticu- 

 lated, elastic fibres ; flowers monoecious in the same spadix, sunk into the concavities of 

 the rhachis : bracts marginal, spreading. 



18. M. Plukenetii, Gr. and Wendl. Leaves obovate, 2-fid (with an angle of 40° at 

 the extremity), inciao-dentate above, pinnatisect below : lower segments linear or oblong-
