the base of the thick pedicels, and a half- superior 4-celled ovarj ohtusely umhonated at 

 the summit. The axils of its branchlcts are j-lj m. apart ; the leaves are 5-10 in. long, 

 l|-4 in. broad, on a petiole 4-6 lines long ; the rachis of the raceme is 3-4 in. long, its 

 nodes 2-2 J lines apart ; the bracts, 2 lateral, 1 exterior, are 1 J line long ; the pedicels 

 2 lines long ; the sepals 1 line long, 1 j line broad ; the petals 10 lines lono*. 

 It has quite the habit of the other species of Chytroma before enumerated.
