Description. — A glabrous evergreen sub-shrub about a foot high, much 
branched, branches ascending. Stem smooth, round, bare and grey below, 
leafy and rough above. Leaves alternate, green, paler beneath, fleshy, spathu- 
late, with a conspicuous blunt notch at apex, tapering to a short petiole, slightly 
spurred, | to i inch long by J to | inch broad. Infiorescence teTminal, 1-2 inches 
across, very leafy, of 2-4 simple or forked scorpioid branches with short-stalked 
flowers in the forks, bracts spathulate, not notched. Buds lanceolate, blunt. 
Flowers | inch across, sessile except the lowest, 5-parted, not opening widely. 
Sepals very unequal, green, fleshy, oblong-spathulate, blunt, resembling the 
uppermost bracts, slightly spurred. Petals spreading, white with a red base, 
oblong-lanceolate, blunt, shortly apiculate, i| times the sepals, with a green 
keel on the upper half. Stamens spreading, shorter than the petals, .filaments 
red below, white above, anthers red. Scales wedge-shaped, orange, longer than 
broad. Carpels erect, red, shorter than the stamens, tapering into long white 
styles. 
Flowers June-July (gentle heat), August-September (cold frame 
and in the open) . Has proved hardy at Dublin ; nearly hardy at 
Waltham Cross (E. A. Bowles). 
Habitat. — San Luis Potosi, Mexico. 
Received from Washington and New York, and also (under the 
name of anopetalum) from Rev. R. H. Wilmot; and Mr. E. A. Bowles 
has had it for some years at Waltham Cross. It was also formerly in 
cultivation at Kew, as shown by an excellent coloured drawing (labelled 
5. oxypetalum) by Mrs. Bernard, with notes by J. D. Hooker and 
W. Watson, preserved in the Kew Herbarium. 
Apparently irregular as regards the number of its carpels. Hemsley 
says 6 and Rose 8. In my plants, received from three different 
sources (though possibly all had a common origin), they are 5. 
The name has reference to the notch which occupies the apex 
of the leaf.

A stout, very fleshy, Mexican evergreen perennial resembling in 
habit and leaf 5. Treleasei Rose, but easily distinguished by its thinner, 
firmer leaves, which are yellowish with a reddish flush (not densely 
glaucous-pruinose), and its larger white (not yellow) flowers, borne 
on long pedicels. Less nearly related to 5. allantoides Rose and 
5. pachyphyllum Rose, both of which have very blunt terete (not 
flattened) leaves. 
Description. — A loosely bushy, very fleshy, glabrous evergreen perennial. 
Roots fibrous. Stems with wide-spreading branches, ascending or sprawling, 
or tortuous when old, smooth, round, about J inch thick, leafy ; flowering 
branches lateral, arising from one of the uppermost leaf-axils, more slender 
than the barren branches, 3-5 inches long, leafy. Leaves alternate, those of 
barren shoots rather crowded, set at right angles to the stem, curving upwards, 
very fleshy, firm, broadly lanceolate or oblanceolate, bluntly pointed or sub- 
acute at apex, narrowing below, sessile, flat on face, about i| inch long, f inch 
broad, J inch thick, glabrous, yellowish green with reddish margins ; those of 
the flowering shoots similar but smaller, about | inch long by \ inch broad. 
Inflorescence compact, hemispherical, about 2 inches across, of several very short 
branches bearing long pedicels. Flowers f inch across, white, starry, on slender, 
pinkish pedicels J inch to | inch long. Buds slender, bulged f way up, where 
the stamens are situated. Calyx small, about \ inch long, divided about half-
