This species much resembles G. Vellosii in general appearance. The axils are 
243 in. apart; the leaves are 3% in. long, 14 in. broad, on petioles 3 lines long; the 
pedunele of the inflorescence is 3-9 lines long, its 3 branches 9 lines long, each much 
divaricated, with 3—4 branchlets, each bearing about 4 flowers on pedicels 2 lines long; 
sepals 3 line long; tube of corolla 3 lines long; the segments 2 lines long. The 
specimen is from one of Martius's Brazilian sets, collected by others, and distributed 
in 1827.

non vidi. 
This species bears all the characters of Geissospermum, and appears very near the 
preceding. Müller was persuaded that it accorded ill with Aspidosperma. It has ashy 
black branches, verruculously lenticellated ; leaves alternate, elliptie, 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, 23-34 in. long, 13-12 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, 14 line long; tube of corolla 43 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.
