§2 PENTANDR1A M0N0GYNIA. Lettsomia. 



Obs. This, when in blossom, is one of the most beautiful of the 

 whole -order; the large, very bright, deep purple flowers make it 

 particularly conspicuous amongst its own deep green leaves, and

 ■with dense deep green foliage.

I cannot help thinking that Dr. Sims's Ipomoea atrosanguinea, 

 Bot. Mag. xlvii. 207 1, is this identical plant, notwithstanding its 

 erect stem and one-flowered peduncles. The figure certainly in- 

 dicates a tendency to become climbing. — It is to be regretted that

 been unable to obtain a single one either in the botanic garden or 

 in any other; it is even difficult to propagate it by layers.

 Berry globular. 



An extensive, stout, perennial, twining plant, a native of the Ma- 

 labar mountains ; from Wynaad the seeds were sent, by Captain 

 Dickenson, to the Botanic Garden at Calcutta, where the plant 

 flowers during the, cold season. The seeds ripen four or five months 

 afterwards. 



Stem and larger branches woody, twining, young shoots villous. 

 leaves round, reniform-cordate, villous; from three to four inches 

 long and from three to five broad. — Peduncles axillary, solitary, 

 generally longer than the leaves, each supporting a yellowish, dense 

 cyme of many sub-sessile, large, pale pink flowers ; embraced by 

 one or more unequal small leaves, the largest of which are shaped 

 like the other leaves, and peduncled ; the smaller ones nearly round, 

 and sessile. Calyx, the exterior leaflets nearly round ; the inner
