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

Sect. 4. Ueechites, /. Mllll. — Corolla-tube campanulate above its cylindrical base. An-

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