144 PENTANDRIA. MONOGYMA. 



surrounded with a gland ulous disk. Berry 2- 

 celled, 2 to 4 seeded. (Stamina sometimes 4.) 



Sarmentose or twining- shrubs similar to the preceding, 

 but brittle or soluble at the joints; leaves simple, ternate, 

 quinate, or pinnate; ilowers in di or tricliotomous, com- 

 l^ound racemes, often corymbose. 



Species. 1. (^. Ampelo'pis. 2. hederacea. Articulations 

 and petioles tumid; racemes cymose, flowers by 2's or 3's, 

 petals 5, cucuUate, unconnected; stam.ina 5, seated upon 

 the petals, anthers horizontal, connected to the subulate 

 filaments about the middle; glandular disk none. Germ 

 conic, 4seeded. Style 0. Stigma minute, glandular. Can 

 this be referrible to the genus Cissus? 3. bipinnata. (C. 

 :$tans. Persoon.) 



The genus Cissvs, with the exception of the above, is 

 entirely tropical; tliere are 10 species in Peru and the 

 West Indies, 11 in India and the neighbouring islands, 1 

 in Arabia Felix, and anotlier common to India and Arabia, 

 2 at the Cape of Good Hope, and 2 in Japan, and 1 ac- 

 cording to Lamark in the Levant. 



No species of this genus appears to afford edible fruit, 

 notwithstanding its near affiiiity to Vicis. I have never- 

 theless been informed that the fruit of the C. bipinnata 

 becomes agreeable when perfectly matured; to my taste 

 they are always nauseous like the berries of the genus 

 Caprifolium.
