614 ONAGRACEAE. —— [Epilobium: 
ing or arcuate above, bifariously pubescent or almost glabrous, usually 
more or less tinged with red. Leaves small, densely crowded, 4-4 in. long, 
shortly petioled, opposite, linear-oblong to oblong or oblong-ovate, more 
or less distichous, glabrous or with a few scattered hairs on the petioles, 
obtuse, fleshy, margins with a conspicuous purplish-red line, obscurely and 
remotely denticulate, midrib prominent beneath. Flowers few towards the 
tips of the branches, white or pale-rose, 1-}in. diam. Calyx-segments 
lanceolate, acute; stigma clavate. Mature capsule #-l} in. long, strict, 
erect, glabrous; peduncle elongating but little. Seeds minutely papillose.

Dr. Cockayne considers this to be allied to H. confertifolium and H. tasmanicum,. 
or, in other words, to belong to Haussknecht’s series Microphyllae. But the distinctly 
hard and woody stems, so very conspicuous in old plants, in my opinion will certainly 
place it in the Dermatophylleae, and in the close vicinity of HE. glabellum. Its nearest 
ally is probably my #. vernicosum, which is at once separated by the very much larger 
flowers and glossy leaves.

—Stems numerous from the top of a woody prostrate rhizome, 2-8 in. high, 
decumbent at the base and then erect or ascending, often reddish, simple 
or sparingly branched, usually with 2 or 4 pubescent lines. Leaves 
opposite or the upper ones alternate, densely crowded, ascending, 4-3 in. 
long, narrow-oblong or oblong-obovate, obtuse or acute, narrowed into a 
short petiole, coarsely and remotely denticulate, glabrous or nearly so; 
lower ones often much reduced in size. Flowers crowded in the upper axils, 
hardly projecting beyond the leaves, large, white, }in. diam. Calyx-lobes 
lanceolate, acute, much shorter than the petals. Stigma clavate. Capsules.

Apparently confined to dry shingle-slopes. A well-marked plant, not easily 
confounded with any other. The large white flowers are almost hidden by the leaves, 
and the ripe capsules hardly protrude beyond them.

stout, hard and woody. Stems numerous, arcuate at the base and 
then erect, slender, rigid, wiry, simple, black or purplish-black, obscurely 
tetragonous, glabrous except 2 or 4 faint pubescent lines on the angles. 
Leaves numerous, usually close-set, opposite or alternate, 1-2 in. long, 
uniform, narrow linear-oblong, obtuse or apiculate, sessile or very shortly 
petioled, rigid and coriaceous, usually dark-red, glabrous, deeply and 
coarsely toothed or almost lobed. Flowers sessile in the upper axils, small,
