unbranched. The leaves are unknown, being shed, as in allied 

 species, before the flowers appear. They leave on the branches 

 rounded, somewhat hollow tubercles, which are usually absent in 

 C. reticulata. The length of the corolla in the latter is only about 

 1 cm. , whereas in C. Pearsoni it is about l - 7 cm. 



8. C. papillaris, L. f., Suppl., p. 242 (1781); Thunb., Prodr., 

 p. 83 (1797). This species is much more variable than I formerly 

 thought. It includes C. glutinosa, Schonl., in Eec. Alb. Mus., i., 

 p. 119. 



" Upper Eegion. Boulders between Nieuwefontein and 

 Alewyn's Fontein, 2,300 ft., 3433; 22.12.08." "Hills around 

 Loeriesfontein, 3,000 ft., 4860; 13.12.08." 



" Little Namaqualand. Among bushes on hillsides above 

 Brakrivier, 1,900 ft. H ft. Flowers whitish brown. 4878; 

 11.12.08." 



" Sandy karroid plain along dry river-bed south of Bakhuis, 



5440." 



"Bushmanland." Eatelkraal ; Sandy plains. Forming round 

 compact cushions 1 ft. in diam. Among bushes. 6213 ; 8.1.11." 



9. C. hemisplicerica, L. Sp., 614. 



"Cape Eegion. Among rocks on summit of Nardouw Kloof, western 

 aspect, 5431 ; 29.11.10." 



The following may also belong to this species, but the material is 

 not sufficient for exact determination : — 



" Little Namaqualand. Broken country along Kansaap Eiver, 

 one day south of Kamabies, 3058; 23.12.06." 



"Bushmanland. Common in rock crevices at Kweekfontein, 

 3,200 ft., 3721; 4.1.09." 



" Upper Eegion. In ravine at Kopje's Kraal, 4871 ; 12.12.08." 



A specimen from " Little Bushmanland, Aggenys, 3028 ; 7.1.09," 

 should be compared with Cotyledon nana, N. E. Br., in Gard. Chron., 

 3rd series, xxx., 270 (1901). It has, like this species, a one-flowered 

 peduncle. It seems to me, however, to be nothing but a weak 

 specimen of C. hemispharica. 



Another specimen, labelled " Fissures in quartzite slopes above 

 Brakwater pools, 6077 ; 31.12.10," differs only from typical C. hemi- 

 splicerica, L., by much narrower and thicker leaves, which in the 

 dried specimens look almost fusiform.
