 liptical, flat, finely veined, fomewhat reticulated, longer than 

 the chillers. Partial flower-ltalks and petals fmooth. — Ga- 

 thered in the Molucca iflands, by the late Mr. Chriltopher

5. R. cochinchinenfis. Br. n. 5. (Helicia cochinchinenfis ;

 folitary, about the length of the leaves. Partial flower-

 Loureiro defcribes as a four-cleft calyx, are really the nec- 

 tariferous glands, united at their bale, and remaining after 

 the petals are fallen. Such a miftake might well render his 

 defcription unintelligible, without a fight of the plant.
