Royal Botanic Gardens, Kew, from the Botanic Garden at Graaff 
Reinet, Cape Colony, in 1908. 
The flowers commence to open at about 11 o’clock in the morning, 
and begin to close at 4 o’clock in the afternoon, apparently irrespec-

M. nobile, Haw., but very distinct from both in its flowers. The 
leaves resemble those of the former species, but are much larger.
