was only ten inches high. R. intricatum, Franch., is most nearly 
allied to R. nigropunctatum. 
Derris oligosperma, a member of the Brachypterum section of the 
enus, is a powerful woody evergreen climber which has been in 
| in the Temperate House at Kew for over twenty-five 
+ was raised from seed sent from the Richmond River in 
Ne ew South Wales, and on flowering in 1904 was described as a new 
Wistaria, On fruits becoming available its true position was 
apparent, and it was found to be identical with the species which 
has heen generally accepted by botanists interested in Australian 
plants as D. scandens. It is not, however, the true D, scandens of 
India ae Indo-China, but a istialet species, and may be regarded 
as its south-eastern representative 
The Cirrhopetalum was first introduced from the Dutch Bast 
Indies by Messrs. Linden of Brussels. It flowered in June, 1890, 
and was named in compliment to the late Dr. M. T. Masters. 
The plant figured was received at Kew from the Royal Botanic 
Gardens, Glasnevin, in 1903. C. Mastersianum is very distinct from 
the majority of the species of this genus in cultivation ; it is most 
nearly comparable with C. gamosepalum, ., but is quite different 
in arias and has the ciliae of the pet tals and dorsal sepal very

Hibiscus asper.—Described in 1849 by J. D. — ( eo Fi. 
p. 228) from an imperfect specimen collected in Sierra Leone, H. 
which he re arded as being aes variable (Annuaire Conserv. & 
ae rd. Bot. Genéve, vol. iv. p. 114). Study of the material now 
ontained in the Kew Herbarium shows that Hl. asper can be 
distinguished from FH, cannabinus by several characters which, 
taken together, seem to warrant its restoration to specific ra ank, 
namely, ‘he repand lobing of the leaf segments, the small sub- 
globose capsule, and the smaller, more rounded, minutely and 
densely tubercled seeds with a ay sinus. The synonymy and 
distribution of H. asper are as follows :—
