 •25 in. long. Floivers in a large erect terminal panicle extending into 

 the axils of the upper leaves, 1-1*25 feet long, 6 in. across, composed of 

 alternate corymbs 2-3 in. long, 1*5 in. across; lower pedicels 1 in. long,

The two varieties are very easily distinguished but they do not differ at all in 

 essentials. The Bornean specimens of C. xanthocoma first received by Miqnel were 

 without fruit; on seeing pods that author himself very jastly reduced his species, as 

 a variety, to 0. timoriensis.
