stamens. In Meisneria, the flowers are tetramerous, the 
capsule two-celled, and the anthers have a short beak. In — 
Rhynchanthera, the flowers are pentamerous, the capsule 
three, four, or five-celled, and the anthers have a long beak, 
oneanther being often nearly twice as long as the rest. Siphan- 
thera cordata has the flowers and capsule of Meisneria, but 
the anthers have a long beak. This character, which gave — 
the name to the genus, does not exist in the Siphanthera — 
tenera, and S. subtilis, (both the same species, judging from 
Pohl’s specimens), the sterile stamina also (as pointed out by — 
Martius), are not completely wanting, and it may therefore be 
well to join Siphanthera to Meisneria. | Poteranthera (ac- | 
cording to Bongard's figure), is near Meisneria, but differs a 
in the pentamerous flowers, trilocular capsule, and uniti 7 
biporose anther. x 
Meriania and Azinea, with biporose anthers, are scarcely " 
any of them known to me; nor is Chastenea, which is “said ; 
to have the habit of Meriania. : 
Cambessedea has the characters of Microlicia, with the ex- 
ception of the straight seeds which fix it in Lavoisiere@, ano — 
the habit is rather different. Chetostoma has precisely the 4 
habit of Microlicia, and the pentamerous species should un- 
doubtedly be there placed. C. tetrasticha is unknown to mé —— 
Lavoisiera is a very distinct genus, consisting of low smooth 
shrubs, closely covered with sessile leaves smooth on their 
surface though sometimes ciliate, and with terminal solitary 
pentamerous or polymerous flowers. de 
The remaining genera have the habit of the larger flowered 
Miconie ; Bucquetia is tetramerous, Davya (with Adelbertia, 
Meisn.), Haberia and Behuria, are pentamerous, with long 
appendages to their anthers; Centromia and Truncaria ate — 
doubtful genera; so also is Graffenrieda, (of which one Sp 
cies is Brachycentrum, Meisn.), unless it be, as supposed by — 
Martius, that genus of Aliajt which Chamisso has 
Jucunda.
