Stems three to six inches long, thread-shaped, a little woolly. Leaves egg- 
spear-shaped, in pairs at each knot of the stem, above green and some¬ 
what hairy, cottony underneath. Leaf-scales four at each knot of the 
stem. Calyx , the three larger leaves composed of strong green ribs, 
connected by a semi-transparent dotted membrane; the two outer spear- 
shaped, green, and which are more like floral-leaves. ( Flowers in ter¬ 
minal racemes, showy, expanding only in sunshine, and scarcely lasting 
a day. E.) Petals yellow, a little toothed on the outer part, nearly 
circular. E.) (The stamens exhibit a curious instance of irritability. 
When touched with a pin or bristle they retire from the style, and lie 
down in a spreading form on the petals. This can be seen only in calm 
warm weather, and when the flowers have not been ruffled by insects.

Whoever has paid attention to the habit of C. Helianthemum will find it 
liable to considerable variation, both in the size and shape of its leaves 
and petals ,* and as to the leaves excavato-punctataf FI. Brit. dotted 
beneath,” with cc little hollows or depressions,” Eng. FI. first noted by 
Lightfoot in his Herbarium, (not in his publication), which has been 
recently revived to corroborate a supposititious species ; we have reason 
to believe that this latter distinction so far from being generally apparent, 
will very rarely be found. Neither is it peculiar to this variety, for Mr. 
W. Christy, (the re-discoverer of Mr. Edward Du Bois’ Croydon plant, 
recorded in Ray Syn.) by whose kindness we are favoured with spe¬ 
cimens now before us, observes, “ Nothing of this kind has ever come 
under my notice, but in the plants I have seen there is no perceptible
