Hab. South Brazil. Introduced by Mrs. Arnold Harrison, of Liverpool, 

 in 1827. Vars. ruber Beer, Q,ndi imrpureus Baker in Saund. Eef. Bot. t. 287, are 

 forms with the leaves more or less tinged with reddish-brown and sometimes a 

 little lepidote on the lower part of the face. G. testaceus E. Morren (M.D.), is 

 a form with brown ovate-lanceolate leaves 4 — 5 in. long, nearly 2 in. broad low 

 down. 



2. C. BROMELioiDEs Otto & Dietr. Allg. Gart. 1836, 298. C. 

 diversifolius Beer, Brom. 76. — Leaves about 20 in a long copiously 

 stoloniferous rosette, lanceolate, a foot long, 1|- in. broad at the 

 middle, plain green on the face, not so firm in texture as in 0. dis- 

 color, and not so white on the back. Flowers in the axils of several 

 of the reduced inner leaves. Calyx-limb -J in. long. Petals white, 

 twice as long as the calyx-limb. 



Hab. South Brazil. Introduced into cultivation by Sello in 1831. 

 Scarcely more than a variety of G. undulatus. Of this also there is a form 

 with reddish-brown leaves. 



3. C. DISCOLOR Otto & Dietr. Allg. Gart. 1836, 299 (M.D.) C, 

 acaulis, var. argenteus Beer. C. acaulis, var. longifolius Hort. — 

 Leaves 20 or more, forming a rosette half a foot high, often over- 

 topped by its stolons, lanceolate, a foot long, an inch broad, much 

 firmer in texture than in C. undulatus, plain green on the face, 

 persistently white-lepidote on the back, very acuminate, the mar- 

 ginal prickles close and minute. Flowers in the axils of several of 

 the reduced inner leaves. Calyx including the ovary f in. long ; 

 segments ovate. Petals pure white, f-1 in. long. 



Hab. South Brazil. First described from the Berlin Botanic Garden in 

 1836. Scarcely more than a variety of C. undulatus. 



4. 0. suAVEOLENs E. Morrcn (M.D.). — Leaves 15-20 in a long 

 rosette, above a foot long, l-li in. broad, moderately firm in 

 texture, often undulated, plain green on the face, white-lepidote on 

 the back, narrowed gradually to the point, the marginal prickles 

 close and minute. Flowers few in a head in the centre of the 

 rosette. Perianth-blade white, oblong, acute, protruding nearly an 

 inch from the calyx. Stamens reaching nearly to the tip of the 

 petals. 



Hab. Probably Brazil. Described from Prof. Morren's drawing made in 

 Sept., 1881. Nearly allied to G. discolor.
