NEW SPECIES OF CRASSULA. 

 By S. Schonland, M.A., Ph.D., F.L.S., & Edmund G. Baker, F.L.S. 



The following twenty-six species of Crassula from South Africa 

 we believe to be hitherto undescribed ; we have also appended a 

 description of C. peploides Drege, published by Harvey in the Flora 

 Capensis, of which fuller material has now been obtained, the plant 

 having been in cultivation. In order to satisfy ourselves in regard 

 to the identity of certain species, we obtained the loan of a portion 

 of Harvey's CrassulacecB from Dublin, and those of the Sherardian 

 Herbarium, Oxford. We have to return our thanks to Prof. Perceval 

 Wright and Dr. Vines for thus assisting us. 



Types of the plants described in this paper will be found in the 

 Albany Museum. Herbarium, Grahamstown ; some of them are also 

 in the National Herbarium at South Kensington. We have arranged 

 the species as far as possible according to the sequence of the groups 

 adopted by Harvey in the Flora Capensis. The genus Bulliarda is 

 not now retained as distinct from Crassula, and the species falling 

 under this group will be found at the end.

Hab. Kareebergen, alt. 1500 ft. ; R. Schlechter, No. 8310. In 

 flower July 24, 1896. 



The leaves of C.pallens are generally acute, while those in C. hrevi- 

 folia are blunt, the pedicels stouter, the sepals a different shape, and 

 the stem-branches and pedicels glabrous.

 crassitie calami, glabriusculus, internodiis + 8 mm. longis. Folia 

 subteretia, subulata, crassa, dorso convexa, supra subplana vel 

 leviter canaliculata, i-Q-^ cm. longa, seusim ad apicem attenuata, 

 subconnata, apice acuta, internodiis multo longiora vel sub^equales. 

 Flores in cymos terminales dispositi, cymis corymbosis, multifloris, 

 ramosis, pedunculatis, bracteis sub pedunculis et pedicellis duabus 

 oppositis, lanceolatis, acuminatis. Pedunculi foliis longiores. 

 Sepala brevia, ovato-lanceolata, subacuta, petalis multo breviora. 

 Petala oblonga, vel oblongo-lanceolata, apice obtusa, basi connata, 

 + 3-5 mm. longa. Carpella oblique obovata, stylis subulatis.
