C. gracilis and C. emarginata, but the lobes do not overlap at the base as in 
C. emarginata. The characters of var. macrocalyx suggest that it may be a hybrid 
between C. emarginata and C. gracilis, rather than an intermediate form. 
Within C. gracilis proper two distinct forms may be recognised. Of these 
one has shorter broader calyx-lobes not overlapping at the base; this form was 
included in C. linoides by Meyer and constitutes typical C’. linoides, Schoch, not 
of Linn. ; the other has long, narrow corolla-lobes and is C. linoides, Thunb., not 
of Linn. and not of Berg., also C. linoides, var. subulata, E. Meyer and Schoch. 
Both forms are included in C. vulgaris, var. intermedia, Cham., and in C. linoides, 
Griseb., not of Linn., whose limitation is here adopted. In Niven’s Tiger Berg 
plant and in Burchell 7147 the calyx-lobes are long as in the second form, but 
broad as in the first. 
6. C. Zeyheri (Prain in Kew Bulletin, 1908, 295) ; stems slightly 
angled, branched upwards, leafy, 1-14 ft. long; leaves narrowly 
elliptic-spathulate, obtuse or subacute, 14-2 in. long, 3 lin. wide ; 
flowers solitary or in 3-flowered terminal cymes; peduncles }—3 
in. long; calyx 3 lin. long, divided half-way ; lobes ovate, obtuse, 
mucronulate ; corolla-tube narrow-campanulate, shorter than the 
calyx; lobes elliptic, obtuse, 5 lin. long, 3 lin. wide; anthers 
straight ; ovary ovoid, obtuse, 3 lin. long. 
Var. 8, angustifolia (Prain |.c.); leaves narrowly lanceolate-spathulate, 14 lin. 
wide ; calyx-lobes ovate-lanceolate, obtuse. C. linoides, E. Meyer, Comm. 179 
(Wupperthal loc. only); not of Linn. 
Coast Reeion: Clanwilliam Div.; Companies Drift, Berg River Valley, 
Zeyher, 1198! Var. 8: Clanwilliam Div. ; Wupperthal, 1800 ft., Drége! by the 
Olifants River and near Brakfontein, Zcklon! marshy soil and along river-banks 
near Clanwilliam, Leipoldt, 360! 
A very distinct species. Ecklon’s and Leipoldt’s specimens are almost inter- 
mediate between the extremely broad-leaved form collected by Zeyher on which 
the species is based, and the very narrow-leaved form issued by E. Meyer as 
C. linoides, This species, unlike the other species of the section, dries black. 
7. C. linoides (Linn. Sp. Pl. ed. 1, 189); stems slightly angled, 
much-branched upwards, leafy, 2-3 ft. long; branches spreading, 
3-10 in. long; leaves linear or narrow-lanceolate, acuminate, 1-1} 
in. long, 1-14 lin. wide; flowers usually 2-5 towards ends of 
branches on alternate peduncles, or solitary; peduncles $—1} in. 
long; calyx 3 lin. long, divided half-way ; lobes ovate-lanceolate, 
acute, with paler submembranous margins; corolla-tube narrow- 
campanulate, as long as calyx ; lobes elliptic, obtuse, 5 lin. long, 
3 lin. wide ; anthers straight or slightly spiral ; ovary ovoid, obtuse, 
24 lin. long. Linn. Sp. Pl. ed. 2, 272; Lam. Encycl. Meth. i. 736 ;
