Cirrhopetalum robustum, though by far the largest, and 
a truly massive species, departs in no respects from the 
genus in any character. It belongs to the group in 
which the inflorescence is truly racemose, and its nearest 
ally known to me is the comparatively dwarf C. refractum, 
Zoll., figured in King’s “Annals of the Calcutta Bot. 
Gardens,” vol. v. t. 28, and vol. viii. t. 119, a native of 
the Himalaya, Tenasserim Mts., and Java. Besides the 
enormous difference in size, C. refractum is distinguished, 
amongst other characters, by the membranous leaves, 
lanceolate and ciliate dorsal sepal and petals, and the 
long, slender, decurved spurs of the column. 
C. robustum was discovered in British New Guinea by 
Sir W. Macgregor, K.C.M.G., the Governor and inde- 
fatigable explorer of that great island; and plants from 
thence were brought to the late Colonel Trevor Clarke, of 
Walton Place, Daventry, by his nephew, Captain Clarke. 
These flowered in March, 1893, and were described by 
Mr. Rolfe under the name of C. robustum. In 1896 the 
same plant was described by Mr. Bailey, Government 
October Ist, 1897,
