the covering becoming denser, almost as on the leaves, in the young 

 tops. Leaves generally about 1*5 cm. long by 6-7 mm. broad, 

 rarely somewhat exceeding this ; on the shorter branches often 

 much smaller, becoming oblong-ovate or lanceolate in shape. 

 Peduncles 1-5-3 cm. long, bracteoles 8-10 mm. long by 2-5-3 mm. 

 broad, pedicels generally 1 cm. long. Outer sepals 1-5 cm. long 

 by -5 cm. broad just above the base, the innermost 3 mm. broad. 

 Corolla apparently about 3 cm. long. 



Near I. crassipes, but distinguished by habit, the dense ash- 

 coloured covering of hairs, the short bluntly ovate leaves, and the 

 ovate outer sepals with a rounded and not enlarged base. Apparently 

 near I. crassipes var. strigosa Hall, f., which I have not seen.

The following plants, not previously cited, are included in those 

 South African forms which I regard as representing I. crassipes : — 



Var. GENUiNA Hall. f. in Bull. Herb. Boiss. vii. 46. 



South Africa, Zeyher, 1846, nos. 1210, 1212. Natal, Macalis- 

 berg, Burke, no. 353, "flowering in October" ; and no. 177 (in herb. 

 Trin. Coll. Dublin). 



Var. LONGEPEDUNCULATA Hall. f. /. c. 45.

Var. ovATA Hall. f. I.e. 47. 



Natal, near Newcastle, alt. 4000 ft., J. M. Wood, no. 6242, 

 ''flowers rose-purple," Jan. 1897; and, without precise locality, 

 J. Sanderson, 1860, no. 276 (in herb. Trin. Coll. Dublin). 



In the Catalogue of Welwitsc/i's African Plants, i. 732, two 

 numbers are assigned to /. crassipes Hook. No. 6128 is /. adum- 

 brata Rendle & Britten, and in my opinion is a distinct species. 

 No. 6130 is a small dwarfed specimen bearing only young flower- 

 buds, and may represent a new species allied to /. crassipes on the 

 one hand, and I. blepharophylla on the other. It differs from 

 the former in the subequal ovate sepals, the innermost only being 

 conspicuously smaller, and the oblong leaves with rounded apex 

 and base recalling those of typical I. blepharophylla, which is, 

 however, distinguished by its narrowly ovate sepals. 



I. OBLONGATA E. Meycr var. hirsuta, var. nov. Foliis ovato- 

 oblongis utrinque marginibusque dense et subferrugine hirsutis ; 

 bracteolis sepalisque dorso hirsutis. 



Leaves generally between 3 and 4-5 cm. long by 1-2-1-5 cm. 

 broad, covered with a somewhat dense covering of rather long 

 appressed stiftish hairs with a tuberculate base. Similar but often 

 paler hairs occur on the bracteoles and sepals.
