but rarely a form possessing exactly intermediate characters may be 

 found which we think probably a hybrid, e.g., near Miller's Point; on 

 Eed Hill, &c. 



13. M. filamentosum Linn. Hill slopes on gravelly or rocky 

 soil, locally frequent ; 8-9. Between Sea Point and Kamp's Bay. 



14. M. mutabile Haw. Eocks from 1,500 feet upwards, 

 frequent ; 8-11. At the foot of the precipices around Devil's Peak 

 and Table Mountain, much rarer near the summit. Petals sometimes 

 dirty white. 



The following 6 species belong to the §Bracteata, which is a well- 

 marked one, known by its very slender petals, the inner rows of 

 which are much shorter and often of different colour to the outer, 

 and so strongly incurved as to invert the outer stamens over the 

 styles. The species, however, except M. bracteatum and M. 

 asperum, are most difficult to separate, confusion having arisen from 

 the upper leaves often being mistaken for bracts. 



15. M. gracile Haw. ? In rough places ; 1. Near Wynberg 

 ranges. An erect, but not rigid plant, with smooth leaves ; inter- 

 mediate between M. asperum and M. bracteatum. 



16. M. anceps Haw. ? Dry low ground, occasional; 12-2. Near 

 Miller's Point ; Eetreat ; Constantia Nek ; Mowbray cutting. A 

 decumbent, pale, glaucous plant. Leaves shorter and broader than 

 usual in the section. Petals often reflexed and twisted. We doubt 

 if this is distinct from M. radiatum. 



17. M. asperum Haw\ Sandy flats and roadsides, frequent ; 

 4-8. Flats about Wynberg, Kenil worth, and Eetreat. A rather 

 stiffly erect plant, with longish very slender petals and leaves. 

 According to Salm Dyck, and in our specimens, the calyx is not 

 punctate-scabrous, nor is it in the least like M. scabrum {vide Fl. 

 Cap. II. 415) though often so named in herbaria. 



18. M. compressum Haw, ? Flats ; 4. By Camp Ground road. 

 Near the preceding but decumbent, with smooth leaves. 



19. M. bracteatum Ait. Mountain plateaux, frequent ; 12-1. 

 Stiffly erect, usually reddish with dark green foliage. Leaves stout, 

 strongly compressed and sharply keeled. The purplish lines on the 

 petals, mentioned by Sonder, do not appear till they are dry ; more- 

 over, they occur in most of the species in this group. 



20. M. radiatum Haw. '? In shrubby places, rare ; 3. Near 

 Eosebank, Bolus, 7946. We doubt whether M. patulum should be 

 kept distinct from this, but have never gathered it. 



21. M. glaucum Linn. Dry sandy places, appears locally 

 frequent; 8-9. Camp Ground; Oude Molen ; beyond Uitvlugt ; 

 Kenilworth. Flowers very showy. Leaves shorter and broader than 

 in the next species, sometimes resembling those of §Falcata. 



22. M. aurantiacum Harv. Sandy or gravelly flats to mountains, 

 rather frequent ; 6-9. Eondebosch and Kenilworth flats ; common 

 at Patrys and Smitswinkel Vleys ; Steenberg ; Vlaggeberg. Flowers 

 much smaller and duller yellow than in the last species.
