Lettsomia. fkntandria mokogynia. 85 



ing-brown, ovate-oblong in our cultivated plants ; somewhat point- 

 ed, size of a filbert, one-celled. — Seeds from one to four ; in our 

 gardens one is by far the most common number ; enveloped in 

 a soft, white, spongy substance, which in drying -separates from 

 the inside of llie peiicarpium and adheres to the seed; which is of an 

 oval shape, and about the size of a small pea. Integuments two, 

 besides the exterior spongy lamina ; the exterior one hard and tough ; 

 the interior one membranaceous, and entering the folds of the cotult- 

 dons. — Embryo as in the other convolvulacecz. 



Obs. The trivial name bona no x is well applied here on account 

 of the charming appearance, and delightful fragrance of its flowers 

 from the time they first expand, about snu set, until sun rise, when 

 they wither, but I doubt if it is the species to which Linneus gave 

 this name ; I rather think it was that which I now call ipomoea 

 grand'ifiora, (Munda valli of Van Rheede.) 



11 . L. unijlora, R.* 



Perennial, twining, hoary. Leaves reniform cordate, acute. 

 Peduncles one-flowered. Berry dry, spherical. 



Ipomoea candicans, Rottler. Mss. 



Teling. Boord*"-Uga. 



This species is very common in forests over the southern parts 

 of the Carnatic, and Tanjore country. Flowering time the cold 

 season. 



Stern twining, woody, running over high trees, &c. young shoots 

 hoary. — Leaves petioled, broad-cordate, or reniform, entire, with 

 the underside downy, particularly while young; from one to two 

 inches each way. — Petioles the length of the leaves, having two glands 

 laterally at the extremity — Peduncles axillary, solitary, length of the 

 petioles, one flowered. — Flowers large, pure white, opening at sun 

 set, and drooping at sun rise.— Bractes two, near the top of the pe-
