glabrous, mottled with olive-green or purplish on a pale ground ;

This plant is of very ambiguous affinity, and is almost certainly of hybrid 
origin between a Duvalia and some other genus, possibly a Caralluma. The 
creeping underground habit of its stems is like that of some species of 
Duvalia and Pectinaria, whilst the outer corona resembles that of Stapelia 
verrucosa, on which account and the presence of the ring on the disk of the 
corolla I place it under this genus. 
{52. 8. Bayfieldii (N. E. Br. in Gard. Chron. 1877, vii. 430-431, 
fig. 66); stems erect, branching at the base, 6-8 in. high, 7-9 lin. 
square, with concave sides and stout ascending or spreading conical 
teeth 1-1} lin. long, puberulous ; flowers 3-5 together, successively 
developed from a 13-2 lin.-long peduncle near the base of the 
young stems; pedicels 8-10 lin. long, puberulous; sepals 3} lin. 
long, lanceolate, acute, puberulous ; corolla 23-23 in. in diam. with 
the lobes spread out, puberulous and green tinged with purplish on 
the back, inner surface smooth or nearly so, with a few short 
scattered hairs in the slight depression around the corona, otherwise 
glabrous, ciliate with rather short simple pale purple hairs on the 
lobes, purple-red, darker towards the tips of the lobes, with the 
disk and basal half of the lobes marked with rather crowded wavy 
_ pale yellow transverse lines; disk flattish, slightly depressed at the 
centre ; lobes 1-11 in. long, 9-10 lin. broad, ovate, acute or shortly 
acuminate, strongly recurved or revolute so as to nearly or quite 
touch the pedicel; outer corona-lobes erectly spreading, with the 
apex slightly recurved, 2 lin. long, linear, abruptly or truncately 
contracted into a slender tooth at the apex, slightly concave- 
channelled at the upper part, dull brownish-red or dark purple- 
brown, mottled with dirty yellowish on the margins ; inner corona- 
lobes 2-horned, dark purple-brown, minutely mottled with dirty 
yellowish ; inner horn 2}—3 lin. long, subulate, erect, with the apex 
very slightly recurving; outer horn about 1 lin. long, deltoid- 
subulate, free to the base. N. E. Br. in Gard. Chron. 1908, xliv.

Oricin : From what I have learnt since publishing this species, I believe it to 
be of garden origin, raised from seed produced by S. mutabilis, doubtless from cross- — 
fertilisation by insect agency with some other species, I have only seen cultivated 
specimens, The stems are very much like those of S. mutabilis, Jacq., but
