Order 81. Convolvulacece. 199 



3. LETTSOMIA. Like the last, but stamens sometimes 

 exserted.

1. RIVEA. 



R. hypocrateriformis. Stem and branches more or less 

 clothed with white hairs, leaves large, round, cordate or 

 kidney-shaped, sepals ovate, obtuse, corolla limb silky out- 

 side, fruit yellowish-brown, nearly dry. Kalmiluta, fanjd. 



Bombay and the Konkans. H. includes in this R. bonanox (D.), 

 which has large night-blowing flowers with a strong smell of cloves, 

 strongly resembling the Moon creeper, but smaller, and said to be 

 called "the Midnapore creeper." I thought the two were quite 

 distinct. 



* R. ornata very much resembles this, but the aepals are larger 

 and more pointed, the stems more hairy and whiter. Higher Ghauts 

 W. of Junar (D.). 



2. ARQYREIA. 



1. A. tilicefolia. A very extensive climber, leaves round, 

 cordate or kidney- shaped, long-stalked entire ; flowers about 3 

 together, handsome, rose-coloured, streaked darker, sepals 

 broad, ovate, much imbricated, increasing with the fruit and 

 covering it, capsule round, brown, seeds 4, downy. 



Not in D. or 6?., but abundant and luxuriant at Kelvi Mahim and 

 Belapore, and probably in other places, as H. has " India, except in 

 the Western dry portion, very common in Bengal, and near the 

 sea." It is very noticeable for its large flowers and fruit, the latter 

 quite covered up by the calyx. R. calls it Convolvulus gangeticus.
