Although at first sight this interesting plant might appear 
to differ generically from the original Ochtocosmus Roraime, 
Benth., described on specimens collected hy M. Schomburgk 
in Guyana, a more close inspection shows those differences 
to be merely specific. The leaves, which have in both 
the same firm texture and glossy surface, are here scattered 
on the branchlets instead of being collected rather densely 
towards their apex: the inflorescence consists of racemose 
fascicles, not of asubcorymbose panicle: the petals become | 
thicker, and might be called almost woody, a character which, — 
connected with all others, marks out the affinity of both 
plants with the genus Ixionanthes, Jack. The definition of 
the Order to which both these genera belong will be shortly 
the object of a separate paper. It suffices now to point out 
their close connection with Erythrozylee on one side, and
