SCHOMBURGK'S GUIANA PLANTS. 301 
ya amongst the Leandre of De Candolle, there are species cor- 
responding in habit to almost every section of Clidemia. I 
am unacquainted with Myriaspora, which, according to all 
accounts is very near Clidemia, but has a ten-celled capsule ; 
Heterostichum has also in many respects the habit of Clidemia, 
but the ovary is said to be destitute of sete. The long lobes 
of the calyx distinguish it from Miconia, as well as the habit. 
The true Miconie are all described as having pentamerous 
flowers, and I have not seen any that are not so. In Tetra- 
2ygia and Ossea, they are tetramerous, the inflorescence being - 
terminal in Tetrazygia, lateral in Ossea; and as these genera 
do not, as far as hitherto known, run into Miconia, they do 
not appear objectionable, although distinguished by no other 
ters than these which are recognised as unavailable in 
the case of Clidemia. So itis also with Ozymeris, which is 
Separated from Miconia by the same character which marks 
the Nianga in Clidemia, the acute petals. Conostegia and 
Cremanium possess more positive characters, the calyptriform 
calyx in Conostegia, the biporose anthers in Cremanium (in- 
cluding Cyathanthera, Pohl), and therefore these genera are 
convenient, although not distinguishable in habit from Mi- 
conia, and although some cases occur where there is a prac- 
tical difficulty in ascertaining whether the anthers are in 
prolonged or not, beyond the partition between their 
The remaining American genera, mostly with larger 
flowers, differ more from Miconia in appearance, notwith- 
standing their somewhat vague character. Phyllopus and 
Henriettea have very fleshy fruits, and the style hairy at the 
base; Henriettea, with the inflorescence of Ossea; Phyllopus 
with a peculiar habit, and the anther almost of Tococa. 
Tococa (including Calophysa?) has almost always the base of 
the leaf, or the leaf-stalk swollen into one or two air-bladders, 
and the flowers paniculate; where the bladders are wanting, 
it may be known from Miconia by the habit, by the more 
completely adherent ovarium, usually crowned by a ciliate
