bright sunshine, and are ay spear to weather-changes, mostly 
closing if the sky be overcast. Here one may note that a large 
proportion of the plants met with up to the present show xero- 
phytic characters ; indeed, a leaf with a ‘‘drip-tip”’ is rare.

Bot. 1898, 141, 345), mention was made of the method by which 
the dis ieibaticn of the seeds of Brunsvigia is effected. Two other 
species were observed in the eastern district of the Cape Colony, of 
purple colour, and with fewer flowers than the Rhodesian species.
