 mens 6 : no rudimentary ones in $ . Ovary 3-celled : stigmas 3, sessile " above the base 

 of the fruit. Berry 1-seeded. Albumen entire : embryo lateral above its base." — Unarmed 

 palms ; " trunk arimdinaceous, annulate ;" leaf-segments flattish, often several cohering ; 

 spadix lateral below the leaves, simply branched, equalling the inner spathe : branches 

 spreading, thickened at the base : flowers sessile : bracts obsolete ; " berry ovoid." 



10. H. pubigera, Gr. and Wendl. (n. sp.). Leaf-segments linear-acuminate, inferior 

 distinct, superior more or less cohering and forming oblong or oblong-linear blades ; pedun- 

 cle and rhachis of the spadix tomentose, at length puberulous : branches 20-30 ; rudiment 

 of the pistil in $ columnar, as long as the stamens. — Trunk 10'— 12' high (Or.); petioles 

 more than 2', leaves 3'-4' long, green with pale nerves, glabrous, chartaceous : inferior seg- 

 ments somewhat distant, H'-2' long, 3'" broad, cohering ones |"-3" broad ; exterior spathe 

 2-kecled, 5", interior 12"-15", peduncle 4"-2", inferior spadix-branehes about 6" long, the 

 latter much thickened at the base, rigid-spreading ; gloinerules somewhat distant : flowers 

 1"'-1V" long. — Hab. Trinidad!, Or., gregarious, covering nearly exclusively the summit of 

 one of the highest mountains near Tocuche. 



6. JESSENIA, Karst.

 Stamens " 20 "-9 : no rudimentary ones in £ . Ovary 3-eelled : stigmas 3, terminal, 

 "slightly excentrical in fruit" {Wendl.). Berry 1-seeded. " Albumen ruminate : embryo 

 axil at its base." — High, unarmed palms ; leaves pinnatisect; spadix simply branched: 

 branches long, much exceeding the conical-acuminate rhachis : flowers sunk into concavities : 

 bracts obsolete ; " berry ovoid."

 minate, alternate, glaucous beneath ; stamens y— 12 ; fertile flowers confined to the lowest 

 part of the spadix-branehes. — Of allied species /. polycarpa, Karst., is said to have the 

 pinnae twice as broad, opposite, acute, stamens 16-20, (Enocarpus Batava, Mart., pinna? 

 not glaucous beneath, opposite, acute, stamens 6 : from both it is distinguished by the small 

 number of ^ flowers. Leaf-segments wholly reduplicate, glabrous, chartaceous, green above, 

 whitish -glaucous beneath, 2J' long, 3" broad ; spadix-brauches fastigiate, 2£' long : ? flowers 

 single, subdistant, confined to one-tenth to one-sixth of the whole branch, $ more contiguous ; 

 inner $ perigone 1 \'" long, valvate : <j> flowers subglobose, 2"'-3'" : both perigones subequal, 

 imbricate. — Hab. Trinidad!, Cr. (" Palma de Jagua"). 



7. EUTERPE, Hart.
