 the corolla-tube ; corolla white : campanulate part of its tube nearly as long as the cylin- 

 drical base and as the broad lobes ; anthers oblong-lanceolate, bluntish, rounded cordate at

43. E. Sagrsei, A. DC. Branches pubescent, glabrate; leaves small, oval or oval- 

 oblong, blunt, mucronulate, rounded or subcordate at the base, shortly petioled ; cymes pe- 

 duncled, shortly racemiform or few-flowered ; calyx-segments glandular, devoid of an interior 

 scale, subulate, one-third to one-fourth as long as the shortly cylindrical corolla-base, which is 

 half as long as its campanula' e part, the latter as long as the broad lobes; anthers oblong-

Sect. 4. Ukechites, J. Miill. — Corolla-tube campanulate above its cylindrical base. An- 

 thers corneous, hastate, with narrow, bluntish, rigid auricles, acuminate from the base, 

 confined to the lower part of the campanulate portion of the corolla, or with a long, 

 membranaceous, terminal appendage. Seeds loosely involute within an acuminate pla- 

 centary scale, terminated by a long filiform beak, which is naked below and longitudi- 

 nally comose above. Cotyledons linear, involute at the margin, as long as the slender 

 radicle. — Climbere or trailing shrubs ; petioles jointed near or at the base. 



44. E. neriandra, Gr. Climbing, pubescent ; leaves obovate-oblong, oval or oval- 

 oblong, blunt or bluntish, often mucronate ; cymes corymbiform, few-flowered ; calyx-seg-

 of the corolla-tube ; corolla yellow : campanulate part of the tube thrice as long as its cy- 

 lindrical base, little longer than its broadly obovate lobes ; anthers abruptly terminated by 

 a linear twisted appendage, slightly hairy on the back ; follicles cylindrical, incurved, sub- 

 striate : seeds as long as the naked part of their beak. — Bot. Repos. 3. 1. 187. Bot. Mag. t. 

 1064. — E. suberecta, Sw. {non Jacq.). Neriandra suberecta, A. DC: but the aestivation is 

 that of Echites. Vinca Iutea, L., or E. Catesbrei, G. Don {ex Catesb. 2. t. 53) is probably
