The scales on tlie seeds are very pretty objects under the micro- 

 scope, much resembling scallop shells of which the ridges are 



produced into free ends. 



H. Mastersianus was founded on Dr. Welwitsch's sheets Nos. 

 4927, 4928 and 5242. Hiern also doubtfully includes a tomentose 

 form (sheet No. 5241), but states that the seeds of this are 

 glabrous, smooth and shining, whereas the seeds of the others are 

 slightly or sparingly papillose. Nothing is said of the scales in 

 any of the forms. The writer has not attached so much import- 

 ance to this difference, because it is found that both the scales 

 and the papillae (or minute warts) are of late formation and occur 

 in fertile seeds only. 



Apart from this character, however, it would appear that the 

 small-leaved, often tomentose, plants on sheets 4927 and 4928 are 

 different species to that on sheet 5242 which comes nearer to H.
