BuTTNEUIACEiE. 



655. Theobroma bicolor, Humb. et BonpL—DC. Prodr. v. i. 

 p, 484. — On the Rio Negro; Schomburgk, n. 870. 



Gardner's n. 933, from Pernambuco, is Guazuma ulmifolia, 

 a plant occurring very frequently in Brazilian and West 

 Indian collections. 



656. Buttneria scabra, Aubl DC. Prodr. v. i. p. 487, an 



Linn.? {Confer St Nil. Fl. Bras. Merid. v. i. p. 143.)— The 

 leaves are often longer and narrower than represented either 

 in Aublet's or in Cavanille's figures. — Moist situations, Cur- 

 rassawaka; Schomburgk, n. 644. 



657. B. ramosissima, Pohl. Ic. v. ii. ;;. 75. t. 149. — The 

 leaves somewhat longer and narrower, and the panicle rather 

 less branched than represented by Pohl. — Currassawaka ; 

 Schomburgk, n. 645. 



658. B. obliqua (sp. n.) ; glabra, ramis teretibus aculeatis, 

 foliis oblongo-lanceolatis obtusis v. breviter acuminatis sub- 

 tus uniglandulosis inermibus, umbellis subsessilibus, tubi 

 staminei lobis brevissimis, sterilibus ovatis obtusis. — Forma 

 foliorum fere B. tereticaulis, fide icone Cavanillesiana, petio- 

 lus tamen multo brevior et inermis, limbus obtusior, basi 

 saepius inaequilaterus interdum subfalcatus. Flores glabri. 

 Sepala lanceolata, acuta. Petalorum cuculli trilobi, lobis 

 laterahbus brevibus oblongis obtusis diversentibus, intermedio 

 calyce parum breviore glanduliformi ovali-oblongo acuto 

 breviter unguiculato. Capsulam non vidi. — Rocks, Pedrero; 

 Sc/iomburgk. 



Gardner's n. 1249, from Alagoas, and Blanchet's n. 2660, 

 from Serra Jacobina, are scarcely distinguishable from St 

 Hilaire's description of his B, austraiis, a species which had 

 been referred to B. tereticauUs of Lamarck. All these are 

 certainly very near to the above B. obliqua, yet a comparison 

 of specimens shows that Schomburgk's plant is certainly 

 specifically distinct from Gardner's and Blanchet's ; nor do 

 any of them quite agree with Cavanille's figure. 



659. B. divaricate (sp. n.) ; ramis aculeatis tomentosiSj
