In the type of C. nana, the branches have not grown on much above the sessile 
heads of flowers ; in C. cirsioides the branches continued beyond the heads have 
longer internodes and narrower leaves, 
2. C. hirsuta (Harv. in Hook. Lond. Journ. Bot. i. (1842) 27); 
mature leaves hairy on the lower surface ; heads sessile or shortly 
peduucled ; outermost floral leaves herbaceous with long white hairs; 
otherwise as C. nana, Nees. Nees in DC. Prod. xi. 163; Lindau in

The ordinary habit of this species is to have trailing flexaose branches 8-12 in. 
long, exactly as in the form ‘‘ cirsioides”’ of C. nana, without heads of flowers in 
the upper axils; this is C. ovalifolia, as correctly figured l.c., the leaves in 
which are not strictly ovate, i.e. they are not wider towards the base. Galpin’s 
1399a has narrowly oblong leaves, and is intermediate between C. hirsuta and 
C. angustifolia. 
3. C. robusta (N. E. Brown) ; branch } in. in diam. 5 apparently 
1-2 ft. long, thinly hirsute; leaves up to 6 by 24 in, oblique 
elliptic, obtuse, narrowed at the base, when mature nearly glabrate 
beneath exeept the midrib; petioles } in. long; heads in 
appearance terminal on stout peduncles 1-3 in. long ; outer floral 
leaves 11 by 1-1 in., elongate narrow triangular, slightly hairy, 
marginal teeth weak, hardly } in. long; proper bracts and calyx 
nearly as in (. hirsuta, with many hairs ; corolla 1 in. long.

4. C. angustifolia (Nees in DC. Prod. xi. 163); lower leaves 
narrowly ma heed up to 2 in. broad, sterile shoots produced beyond 
the heads with linear leaves 3 by }—} in., often undulate subcrenulate
