5. mexicanum was grown in the Succulent House at Kew until quite 
recently. The presumption is that Masters compiled his description 
from the plant at Kew, where he obtained much of the material for his 
monograph. There is no record as to the source of the Kew plant. 
The species came to me from New York Botanic Garden, and also 
from the Villa Thuret, Cap d'Antibes (without a name), and I have 
seen it at Bremen (labelled "sp. aus Mexico") and Berlin (labelled 
reflexuni) ; also, to my surprise, as a pot plant in a cottage window 
at Thomastown, in Co. Kilkenny, in Ireland.

S. Palmeri and 5. compressum are closely allied Mexican plants. 
5. variicolor is Chinese, belonging to the group Japonica of 
Maximowicz. The remaining four species belong to a well-marked 
group of the Western United States, some of which have been placed 
by Rose in a separate genus, Gormania.

One of the best and most distinct of Mexican Sedums, the abundant 
drooping sprays of golden blossom contrasting finely with the glaucous 
foliage. It is also one of the hardiest. 
It is close to 5. compressum, which, however, has acute leaves, 
while those of Palmeri are rounded or quite bluntly pointed. The 
latter are, moreover, of a different tint, being very glaucous, while 
those of compressum are rather of a pale green, tending to be suffused 
with red as they get old. 
In its bare, sinuous stems and rosette-like terminal clusters of 
entire spathulate leaves, the plant recalls the European 5. Ana- 
campseros. 
Description. — A glaucous evergreen perennial of sprawling habit. Stems 
rather sinuous, bare and rooting below, round and smooth, decumbent, with 
ascending branches, 6 to 9 inches high. Leaves spathulate, entire, about i by f 
inch, rounded or very bluntly pointed at the apex, glaucous, somewhat reflexed, 
forming, save when in full growth, a loose terminal rosette. Flower-stem erect, 
lateral (in early stage drooping and appearing terminal) , slender, 2 to 4 inches long, 
bearing small scattered leaves ; in strong plants several axillary flowering stems 
are also produced from lower down the shoot. Inflorescence cymose, of 
several drooping, wide-spreading branches, 1-4 inches long, bearing on their 
upper side a double row of crowded flowers, each with an ovate bract, the lower 
ones with pedicels equalling the flowers. Flowers f inch across. Sepals pale 
green, unequal, lanceolate to linear-oblong, rather acute, the exterior one much 
larger than the others. Petals orange, about equalling the longest sepaL lanceo.
