866 NEW SPECIES OF CRASSULA. 



stems from the crown which spread on all sides, but they are only 

 at most 4-5 cm. long, whereas in C. albicaulis they are 15 cm. or 

 more. Another difference is that in albicaulis the sepals are about 

 two-thirds of the length of the corolla, whereas in the present 

 species the sepals and petals are nearly the same length. The 

 sqnamge are rather noticeable on account of their somewhat 

 peculiar shape — the short stipe is abruptly transversely dilated, 

 and subsimilar in outline to the section of an Agaricus. A plant 

 gathered by R. Schlechter, No. 4920, at Piquenierskloof, alt. 850 ft., 

 may be the same as above.

 longa. Flores cymosi, pedicellis gracilibus. Calycis lobi lanceolati, 

 acuti. Petala ovata, acuta, 5 mm. longa. Carpella petalis breviora, 

 stylis subulatis, sqiiamis rectangulari-cuneatis. 



Hab. Table Mountain, Kasteelspoort, on rocks ; Capt. Wolley 

 Dod, No. 1624. 



Belongs to Crenato-lobatw. This seems almost certainly the 

 plant Harvey took for C. dentata Thunberg (see specimens in his 

 herbarium). C. dentata Thunberg, var. a, minor Herb. Harvey, is a 

 more slender plant. Petrogeton typicum E. Z. (— C. Petrogeton 

 Walpers) belongs to this variety. We have carefully compared 

 Thunberg's description of his dentata [Flora Capensis, 293) with the 

 present species, and as there are several points of dift'erence, we 

 have ventured to describe the latter. The stem in the present 

 species is about 4 cm. high, the plants in the Harveian Herbarium 

 being rather more, and the leaves are not cordate, the original 

 description (of C. dentata) describing the stem as " vix ullus vel 

 brevissimus," and the leaves as " cordata." Harvey remarks 

 C. dentata Thunb. has " something the habit of Chrysosplenimn 

 oppositi folium,'' a remark which is applicable to the present species. 

 The two plants in Harvey's Herbarium referable to C. Pro- 

 montorii were collected, one by Harvey himself, the other by C. 

 Wright, No. 558, both without definite locality. 



C. confusa, sp. nov. Planta omnino glabra. Caulis herbaceus, 

 + 4 cm. altus. Folia subreniformia, in statu siccitatis, membran- 

 acea, petiolata, basi truncata, margine Integra vel subintegra, 

 viridia, lamina 1-2-1 -8 cm. lata, 7-9 mm. longa, petioli 5-8 mm. 

 longi, patentia vel erecto-patentia. Flores cymosi, pedicellis gracili- 

 bus. Calycis lobi petalis triplo breviores. Petala ovato-acuminata, 

 2-2-5 mm. longa. Carpella oblique obovata, stylis subulatis, 

 tenuiter recnrvis, squamis ovatis, apice obtusis. 



Hab. Koudeberg, alt. 2400 ft. ; B. Schlechter, No. 8727. In 

 flower Aug. 28, 1896. 



This plant belongs to the Crenato-lohatcB, and is closely allied to 

 C. nemorosa Endlicher. It may be well to contrast the differences 

 these species exhibit : —
