122 schomburgk's guiana plants. 



burgk, n. 11 French Guiana; Herb. Par. n. 120, and in 



almost all American collections. 



647. A species ofSida, allied to S. rhombifolia, but a larger 

 plant, with broader and more canescent leaves, larger and 

 more canescent calyxes, and larger carpels. There are, how- 

 ever, many described species allied to S. rhombifoUa, which 

 are unknown to me, and I am unable to give any positive 

 characters to distinguish this one. — British Guiana; Schom- 

 burgk, n. 476. 



648. S. althmfolia, Sw. ^. aristosa, DC. Prodr. v. i. p. 465. 

 S. multiflora, Cav. DC. I.e. 464.— British Guiana; Schom- 

 burgk, n. 495. French Guiana; Leprieur, Herb. Par.n. 124. 

 Alagoas; Gardner^ n. 1246; Ceara, Gart/ner, n. 2400, and 

 in many Brazilian collections, I have from the West Indies 

 both of De Candolle's varieties. 



Gardner's n. 323, from the Organ Mountains, n. 1465, 

 and 1466, from Ceara, and n. 2485, from Piauhy, are all 

 species of Sida allied to the three preceding or^es ; n. 1464, 

 from Ceara, which I have also from the West Indies, appears 

 to be S, maculata, Cav., a species remarkable for the large size 

 of its flowers; n. 866, from Bahia, is 5. Alpestris^ St Hil.> 

 which is not probably to be distinguished from S.floribunda; 

 Humb. et Kunth, and S. paniculata, Linn., the peculiarities 

 ascribed to each supposed species, being found alike in the 

 West Indian, the Peruvian, and the Brazilian specimens ; 

 n. 1 467, from Ceara, is S. micrantha, St HiL 



649. Gaya subtriloba, Humb. et Kunth, Nov. Gen. et Sp. v. v. 

 p. 270. t. 476. — The leaves in ray specimen are none of thena 

 lobed, but it agrees in every other respect with Kunth's 

 figure and description — British Guiana; Schomburgk, n. 682. 



Gardner's n. 1245, from Alagoas, n. 2053, from Piauhy, 

 and n. 2401, from Ceara, belong to Gaija ; n. 2486, from 

 Piauhy, the same as Blanchet's n. 2642, from the Serra Jaco- 

 bina, appears to be G. aurea, St Hil. ; but my specimens are 

 in flower only. 



650. Malachra capitata, L.—DC. Prodr. v. i. p. 440.— 

 British Guiana ; Schomburgk^ n. 889.
