This species irmch resembles O. Vellosii in general appearance. The axils are 

 2^-3 in. apart ; the leayes are 3| in. long, 1 J in. broad, on petioles 3 lines long ; the 

 peduncle of the inflorescence is 3-9 lines long, its 3 branches 9 lines long, each much 

 diyaricated, with 3-4 branchlets, each bearing about 4 flowers on pedicels 2 lines long ; 

 sepals I line long; tube of corolla 8 lines long; the segments 2 lines long. The 

 specimen is from one of Martius's Brazilian sets, collected by others, and distributed 

 in 1827.

 This species bears all the characters of Geissospermum, and appears very near the 

 preceding. Mliller was persuaded that it accorded ill with Aspidosperma. It has ashy 

 black branches, verruculously lenticellated ; leaves alternate, elliptic, obtuse or more 

 acute at both ends, very glabrous, membranaceous, fuscous, opake above, with 8-10 pairs 

 of nerves prominulent, very horizontally patent, with others shorter and intermediate, 

 reticulated, 2|-3 J in. long, l^lf in. broad, on petioles 5 lines long ; panicles lateral, 

 nearly sessile, many-flowered, without pedicels, with a small pubescent bract; sepals 

 ferruginously hirtellous, oblong-ovate acute, 1^ line long ; tube of coroUa ^ lines long, 

 fulvo-hirtellous, somewhat inflated above; segments glabrous, oblong-ovate subacute, 

 as long as the tube ; ovaries glabrous, with ovules in pairs in 4 series.
