The above description is compiled from that of Haworth, and 

 renresents all that is known of this species, for no plant at 

 nresent in ciiltivation that is knovm to me corresronds to the 

 above characters. But I have a plant, collected nerr l'-e.t jesfon- 

 tein, and sent to me by '^v . i^ole Evans under no. 968 that I strong- 

 ly'' susnect to be Gr. gibbosum. ^t is reproduced in ^ig. 75, and 

 consists of a number of grov/ths crowded upon a very shortly bran- 

 ched xTOody rootstock, forming a hemisrhericsl tuft about 4 inches 

 in diameter. '^ecY growth is lo— 1-^5- inches long and 7-8 lines 

 thick at the lov/er part, stoutly conical-ovoid, tapering from about 

 the middle into a conical obtuse T^oint, slightly keeled dov/n the 

 front, v.dth the smaller leaf (m.easuring from the base of the 

 fissure) about half as long as the larger one; at first they are 

 closely rressed together, afterw-rds more or less separating, 

 smooth, quite glabrous, of a light and somewhat j'-ellowish-green 

 at the bnsl part, suffused with ^ur^le on. the upper part, and 

 with a frin"^ glaucous tint. I have not seen a flower of it. 

 If this proves to be Haworth 's ^•^. gibbosiim, then •i''ig. 75 will 

 represent its appearance as it grows under natural conditions.
