Mammillaria—continued. 
M. p. texana (Texan). This principally differs from the type 
in the larger number of radial spines (there are from twelve 
to twenty in M. pusilla), and in the dark green colour of the 
tubercles; the exterior hair-like spines cover the whole plant 
as if with a coarse wool. Texas. 
pycnacantha „ ji. deep sulphur-yellow, five 
or six on the top of the plant, very handsome ; petals linear- 
oblong; anthers orange. July. Stem 6in. high, of a rounded 
form, but nearly cylindrical ; tubercles large, nearly lin. broad 
at base, obscurely two-lobed; axille filled with dense white 
wool; spines twelve to sixteen, woolly at base, -emba and 
recurved, pale brown. Oaxaca, Mexico. (B. M. 3972.) 
M. raphidacantha (needle-spined). f. purplish-violet, about 
lin. in diameter. Stem cylindrical, 3in. to Sin. high, lin. in 
diameter, slender; tubercles short, conical, jin. long, dark green ; 
ines eight or nine, in one series, spreading, star-like, close set, 
jin. long, white. Mexico. A very pretty species, the peculiar 
spines somewhat resembling crystals of ice. 
M. recurva (recurved). fl. red, disposed in zones round the 
summit of the plant. Stem ee sometimes divided; axils 
with abundant white wool; tubercles subtetragonous, com- 
ressed ; spines few, very long, sub-angular, white, or nearly 
awn- coloured. Mexico, :

yellowish spines gin. to zin. long. Mexico, 1836. A most desirable,

lengthened out transversely; the rest are prominent, sub-hemi-

whence, in the upper ones, rises a fascicle of from three to five 
spines; the other tubercles are spineless, the spines being 
deciduous. Mexico, 1838. (B. M. 3984.)

ORD. Apocynacee. A genus comprising about forty-five 
species of tall climbing shrubs, natives, for the most 
part, of tropical America. Flowers yellow, white, or 
rarely violet, often large, in simple racemes; calyx five- 
parted; corolla funnel-shaped; tube cylindrical or ovoid; 
throat campanulate or oblong, without scales. Leaves 
opposite, feather-veined. M. suaveolens, the only species 
yet introduced, is a very handsome, half-hardy, deciduous 
climber, thriving in a compost of good peat and turfy 
loam, in equal parts, to which may be added plenty of 
silver sand. It forms an excellent .subject for planting 
in a conservatory and training up a rafter, or may be suc- 
cessfully cultivated, in some parts of England, in the 
open air, if provided with protection in winter. Pro- 
pagated by cuttings, made of small, stiff, side shoots, - 
about 3in. long, and inserted in sand, under a bell glass. 
ag plant rarely succeeds when grown in pots.
