MR. G. BENTIIAM ON BIXACEiE AND SAMYDACE.E. 93 



Panama, Trinidad, Guiana, Surinam, Hostmann, n. 495; Cayenne, 

 New Grenada, Tropical Brazil, Gardner, n. 1451 ; Peru, Ruiz 4- Pa- 

 von, &c. 

 Spruce's n. 4894, from Tarapoto, may be a variety of this species, but 



it is remarkable for the large panicles of flowers much smaller than 



usual. 



8. B. Vellosit, Gardner in Hook. Lond. Journ. Bot. ii. p. 331. (Boca 

 serrata, Veil. Fl. Flum. v. t. 113.) 



Hab. Brazil, near Rio Janeiro, Gardner, n. 310. 



I have considerable doubts whether this is more than a variety of B. guia- 

 nensis. 



9. B. ibaguensis, Tul. in Ann. Sc. Nat. Par. ser. 3, vii. p. 290. 

 Hab. Near Ibague in New Grenada, Goudot. 



United by Grisebach with B. guianensis, it appears to me to differ in 

 several points. It is readily recognized by its sessile flowers. 



10. B. brasiliensis (Kuhlia brasiliensis, A. Gray, Bot. Amer. Exp. 

 Exped. i. p. 73. Ascra brasiliensis, Schott in Spreng. Syst. Cur. Post. 

 p. 407). 



Hab. Brazil, province of Rio Janeiro, Schott. 



This is referred by Clos to the B. Vellosii; but it appears to be quite 

 distinct in the more coriaceous leaves narrowed into a longer petiole, the 

 smaller flowers, &c. 



11. B. mexicana, A. Gray, PI. Ervendb. 



Hab. Wurtenberg, near Tantoyuca, province of Huasteco, Mexico, 



L. C. Ervendberg. 

 This species is fully described by Asa Gray in an enumeration of Er- 



vendberg's plants, now in the press. 



12. B. nitida, Spruce, sp. n. Foliis ovali-oblongis acumiuatis gla- 

 bris nitidis penninerviis, panicula ramosa tenuiter canescente. — Arbor 

 patula, 40-pedalis. Folia 4-6-pollicaria, obtuse et remote dentata, 

 basi obliqua, supra ad petiolum brevem glandula scutellata aucta. 

 Panicula laxa. Flores pedicellati, flavo-virides. Petala et sepala 

 1 lin. longa. Capsula globosa, glabra, indehiscens, 4 lin. diametro. 



Hab. Along streams near Tarapoto, in Eastern Peru, R. Spruce, n. 4512. 



§ 3. Flores ad apices ramorum v. rarius ad axillas breviter simpliciterque 

 racemosi v.fasciculati. 



13. B. grandiflora, Spruce, sp. n. Foliis ovali-ellipticis 3-nerviis 

 glabris, floribus in spica terminali paucis dissitis sessilibus. — Arbor 

 parva, vage ramosa, 20-pedalis. Folia 4-6-pollicaria, remote calloso- 

 dentata, subcoriacea, usque ad apicem trinervia ; glandulis nullis nisi 

 ad dentes marginales. Spica interrupta, 2-3-pollicaris. Flores pauci 

 quam in ca;teris speciebus majores. Sepala valvata et petala inibri-
