31 The following species are mostly additional to those already 

 published in The hardeners' Chronicle, 1922, vol. LXXI, p. 193, and 

 1925, vol. LXXVIII, p, 450, and indicate that this genus is a very 

 large one. A century ago abo\it ten species were knov.n; at the 

 present time (including those described below) over ninety species 

 have been described, most of which I have in cultivation, and con- 

 sidering the vast area in South Africa in the region where these 

 plants thrive that is as yet unexplored, there are doubtless very 

 many more awaiting discovery, besides several nev/ ones ^ possess 

 that will be described later. 



As I have previously stated, it is almost impossible to make 

 descriptions of these very remarkable plants from v;hich they can be 

 identified, as they have no parts or organs by which they can be 

 contrasted for that purpose, -^nd it is very unfortunate that very 

 little is known of their range of variation, as this has never been 

 investigated in their native country. But from material that has 

 been sent to me from the same general region inhabited by a given 

 species, received sometimes from the same contributor at different 

 times, sometimes from different contributors, I find that some 

 species undoubtedly very considerably in appearance, so much so, 

 that without knovrledge of their origin, most would con- 



32 sider them, in certain cases, to be distinct species. ^I find this 



to be particularly the esse with '-'onophytum rl^citum, C. p:olulum, and 

 C. truncatellum, and species of Lithops also vary very much. 

 Therefore, plants from the same general locality thpt show some af- 

 finity to one 8 other, and at the same time seem quite distinct 

 in markings or a'^pearence should be suspected to be variations of 

 one species until flov/ers or other characters definetly prove them 

 to be distinct, '"hen raised from seeds taken from the same plant, 

 I have found some species to vary greatly, and in the case of
