FLORA OF SOUTH AMERICA. 367 
racemosi, 6-10-flori, paniculam parvam efformant foliosam ad 
apices ramorum. Pedicelli vix linea longiores, singuli ad 
axillam bracteee minute orti. Flores odorati, parvi. Sepala 
vix lineam longa, ovalia, glabra. Petala alba, 3 lin. longa, 
obovato-oblonga, basi angustata, obtusa. Filamenta petalis 
subzequilonga. Anthere in specimine meo omnes a vermibus 
destructe. Ovarium glaberrimum. Stylus petalis paullo 
brevior. 
This genus differs from Terntroemiacez in its definite sta- 
mens, but in most other characters it approaches nearer to 
them than to any other order I am acquainted with. The 
habit is somewhat different, as well as the consistence of the 
petals. The frult is unknown to me, but, judging from the 
somewhat enlarged ovaria, it appears to be capsular and likely 
to open in valves, leaving the central column free. 
CLUSIACE. 
The undescribed genera and species of this order in the 
tropical forests of America are probably numerous, but owing 
to the difficulty of drying specimens, those which are brought 
home by collectors are few and imperfect, and the great 
variety of forms observable in both male and female flowers 
indicate a variety of groups, whether generic or sectional, as 
yet but very ill defined. Some of the following, which I 
have referred to published genera, may possibly, therefore, 
belong to others at present undescribed, but upon which 
my materials do not enable me to form any decided 
opinion. 3
