1. ©. erubeseens Sims in Bot. Mag. (1808) t. 1067.—Perennial ; usually 
more or less silky-pubescent, rarely almost glabrous. Rootstock stout, 
creeping ; stems few or many, slender, prostrate and trailing, variable in 
length, 2-12in. long or more. Leaves petiolate, very variable in size and 
shape ; the lower ones with a blade }-3in. long, oblong-cordate or hastate, 
obtuse, quite entire or sinuate; in large specimens gradually passing into 
much narrower acute or acuminate upper ones, with diverging entire or 
irregularly toothed basal auricles; in small specimens the narrow cauline 
leaves are often wanting. Peduncles as long as the leaves or nearly so, 
l-flowered, with 2 subulate bracts some distance below the calyx. Sepals 
broadly oblong, obtuse, silky. Corolla variable in size, 4—3 in. diam., white. 
Capsule 7-4 in. diam., globose, 2-celled. Seeds 4, rough, brownish-black.—

A remarkably variable little plant, closely allied to the common C. arvensis Linn. 
of the Northern Hemisphere. I have seen no specimens of Mr. Petrie’s C. fractosaxosa, 
(Trans. N.Z. Inst. xlv (1913) 271), but, judging from the description, and recognizing 
how variable C. erubescens is, I should imagine that it is nothing but a reduced state 
of that plant, with the leaves and stems rather more hairy than usual. 
4. DICHONDRA Forst. )7 > 
Small prostrate or creeping perennial herbs. Leaves orbicular-cordate 
or reniform, entire. Flowers small, solitary, axillary. Sepals subequal, 
distinct to the base. Corolla broadly campanulate, deeply 5-lobed’; lobes 
induplicate. Stamens shorter than the corolla; filaments filiform ; anthers 
small. Ovary of 2 distinct lobes or carpels, each 1-celled with a basal style 
and 1 or 2 ovules. Capsules 2, membranous, erect, 1- or rarely 2-seeded, 
indehiscent or bursting irregularly. 
A small genus of 4 or 5 species, widely spread in tropical and subtropical countries.

1. D. repens Forst. Char. Gen. (1776) 39, t. 20.—A small silky- 
pubescent creeping herb ; stems slender, 2-12 in. long, rooting at the nodes, 
branched, often forming broad matted patches. Leaves alternate or tufted 
at the nodes, usually on long petioles; blade 4-lin. diam., reniform, 
emarginate or rounded at the apex, silky on both surfaces. Peduncles 
as long or longer than the petioles. Flowers small, greenish-yellow, 
about gin. diam. Sepals obovate, silky. Corolla about equalling the 
sepals, rarely slightly longer. Capsules enclosed in the persistent calyx 
and shorter than it.—Forst. f. Prodr. (1786) n. 134; A. Rich. Fl. Nouw.
