This interesting shrub grows in the understory of low- 
land tropical forests from Guyana throughout the lower 
Amazon basin and with disjunct populations in the 
coastal forests of the State of Bahia. The species has 
been collected only twice in the last fifty years, and no 
collections of it are known from Bahia since 1850. 
Brunfelsia Martiana is closely related to B. amazonica 
Morton and B. guianensis Benth., which also have 
rather small, greenish white flowers and occur sym- 
patrically with 2B. Martiana in the middle Amazon. 
B. Martiana differs from 2B. amazonica in having larger 
leaves (10-25 em. vs. 6-12 em.) with more lateral nerves 
(8-12 pairs vs. 5-8 pairs) and much shorter pedicels 
(8-6 mm. vs. 13-20 mm.). It differs from B. euianen- 
sis in having larger (10-25 cm. vs. 6-15 em.) oblong 
leaves with more lateral nerves (8-12 pairs vs. 4—5 pairs), 
a calyx which is usually narrow-tubular, not ovoid- 
‘ampanulate, and a corolla tube which is rarely more 
than twice as long as the calyx. In B. euranensis, the 
tube is frequently 2) to 8 times as long as the calyx.
