2. C. calycina Webb. 
St. more robust and wiry or less finely capillary and cobwebby 
thau in C. Epithymum, less matted or intricately intertwining 
and more frequently spirally curling or tightly twisting in coils 
or rings round the branches of the pi. on which it grows, dark 
red or purple ; heads of fl. 2^-3^ lines in diam. globose sessile 
bracteolate p. or rose-col. ; fl. not quite sessile densely crowded 
rather large; cal. deep p. or rose-purple large subcon$picuous 
nearly or quite as long as the cor. deeply 5-cleft or o-partite, lobes 
membranous large broadly oval or oblong -ovate subobtuse reach- 
ing nearly to the tips of the cor. -lobes , not nerved or carinate ; cor. 
blush-p. or flesh-col., the lobes at first erect then spreading or 
reflexed, otherwise, like the stam. with their scales, as in C. 
Epithymum ; styles distinct divergent from their base. — WB. iii. 
37, t. 142. — Mad. on low bushes of common E. Broom (Saro- 
thamnus scoparius (L.), Serra do Estreito, from the late T. II. 
Edwards Esq. May 16th 1839 and May 1st 1848. — Pl. stouter 
larger and more rubescent altogether than in C. Epithymum ; st. 
thicker or les3 cobwebby and darker red or purple with ( in Mad.) 
larger thickly crowded heads forming a dense mass of fl. of a 
beautiful p. or rosy and w. hue like a bunch of fl. of Tamarix 
gallica L. Fl. very fragrant !, in bud deep rose-red or purple, 
passing as they expand from p. to pale blush or w. Stam. ex- 
serted, shorter than cor.-lobes. Styles and stigmas altogether 
dark crimson or atropurpureous, ultimately longer than the 
stam. Scales at base of fil. precisely as in C. Epithymum above. 
Seeds 2 only perfected, large globose or subtrigonal with 2 flat- 
tened and one convex (dorsal) side, like that of a Convolvulus, 
brown or fawn-colour, finely and closely granulate. 
Willkomm and Lange strangely refeii C. calycina Webb to 
their C. planiflora Ten., which they distinguish from C. Epi- 
thymum by its carinated cal.- and cor.-lobes and by the latter 
never being reflexed. The former of these characters applies 
indeed to C. Episonchum WB. iii. 36, 1. 141 ; but neither of them 
to C. calycina. 
It may however be well doubted whether either C. calycina 
or C. Episonchum Webb is really distinct as a species from the 
polymorphous C. Epithymum.
