developed flo nor capsules are kno A. crassa differs from all 
other species oe Aveta by ts grieiney stamens and acutely angled, 
almost winged, capsule; but it agrees in other respects with that 
genus as extended by Bureau aud K. Schumann in Mart. Fl. Bras.

On the strength of a superficial resemblance which had been noticed 
previously by A. P. de Candolle (Prodr. vol. ix. p. 158), Miers included 
A. crassa and A. trichoclada in his new genus Cremastus. Cremastus 
has now been restricted of ny and ch in aye 214) to C. a 
airs. 
The indumentum, calyx, corolla an < of A. crassa are similar to 
those of Distictis, Bur., and this led Birean and Schumann, who had 
not seen the capsule, to pore the species to that genus. Apart from 
the very different capsule, Distictis, Bur., may be distinguished by the 
thickened bases of the filaments and the silanieetiade ovules. As has 
been pointed out by Schumann (l.c. 175), Distictis, as define

Kuntze, Lexicon, p. 182).
