THE AFRICAN CYCADS 49 



Encephalartos Lehmanni, as it occurs on Junction 

 Farm, looks so much like E. Friderici Guilielmi that even 

 a botanist might not notice that there are two species, 

 since both have the massive trunk and crown of very 

 pale leaves. In both the leaflets usually have smooth 

 margins, but in E. Lehmanni there are occasionally one 

 or two small spines. This might not seem to be an 

 important characteristic, were it not for the fact that 

 in other localities the spines become larger and more 

 numerous, until the plant looks so different that even a 

 layman could not confuse it with the Kaiser's cycad. 

 There is really a series whose extremes are easily recog- 

 nizable species between which are intergrading forms 

 that could hardly be identified by leaf or stem char- 

 acters. However, the male cone of E. Lehmanni is 

 not very hairy and has a distinct reddish color, 

 while the other has a cone so densely covered with 

 long, Hght-brown hairs that the solid portion — a 

 dull green when the hairs are removed — is entirely 

 hidden. 



At Grahamstown, about a hundred miles southwest 

 of Cathcart, E. Lehmanni has such jagged leaves that 

 one risks injury to hands and clothes in getting material. 

 The leaves also have little of the grayish color so char- 

 acteristic of the Queenstown and Cathcart specimens. 



Professor Shonland, formerly director of the Albany 

 Museum at Grahamstown, but now professor of botany 

 in the Rhodes University of that place, gave me the 

 benefit of his extensive acquaintance with the cycads 

 of the vicinity. It also increased the value of the field 

 study to have associated plants pointed out and named 

 with such authority.
