 — Petiol very short, thick, margined, furrowed.— Corymbs lateral, 

 from the vestiges of the fallen leaves, much shorter than they, 

 rounded, consisting of very numerous, closely approximate, spread-

 from three to four inches long, bearing at the apex two or three 

 oblong, sub-opposite, floral leaves, from two to three inches long, 

 on very short, membiane-margined, widening petiols. — Partial ones 

 (of the umbels) flattened; the lowermost an inch or an inch and 

 half long, the rest becoming gradually shorter; each supported by a 

 large, ovate, membrane-maigmed, deciduous bracte. — Pedicels about 

 half an inch long, crowded into many-flowered umbels; each sup- 

 ported by an oblong, membranous, concave bracte. — Calyx dotted ; 

 latinia lanceolate, slightly ciliate. — Corolla rotate, doited, four 

 times as long as the calyx; lacinice, linear-lanceolate, acuminate, 

 deeply divided, nearly half an inch long ; during aestivation twisted, 

 sub-cylindric. — Anthers sessile, large, membiaue-maigiued ; termi- 

 nating with a long, membranous, delicate, lanceolate process, and 

 firmly uniting into an oblong tube. Ovary ovate, small. Style 

 capillary, a little longer than the tube formed by the anthers, — N. VV.
