M. Sphacrotricha ('•yn Candida) greyi.sh 
white covered with soft sillty ,«pines. 3/6 each. 
M. Stella-Aurata (Golden Star), when in

star-like rosettes of yellow spines, l/- 
M, Uncinata, 2/6. 
M. Viviparus, Bird’s Nest Cactus. Whi le 
plant covered with purple and white spines. 
h'lowers very large and showy, bright purple,

M. Wildiana, a very distinct and pretty 
species, closely surrounded by oflfsets, flowers 
rose, 2/- to 3/6 each. 
M. Wrightii, a charming species; mo. 
select, 3/6. 
HARDY OPUNTI/E (Prickly Pear). 
These usu.allv have flattened joints which are more or less spiny, are rapid growers, and great 
bloomers ; and for making a permanent evergreen covering as well as for massing, either .alone or 
with other plants, their use is r.apidly extending. Many parks and estates are using them thus, and 
we hear much commendation and no complaint. 
O. ARENARIA. Small-jointed, having a rather compact clustered habit of growth. Spines long 
and prominent, usually with dark tips, sometimes reddish brown, with lighter tips, blowers 
yellow. Rare and distinct sort, 2/6. 
O. .-\RIiORESCENS. Candelabrum Cactus. A distinct sort with dark green cylindrical joints, 
and grey spines. Flowers purple, fruit yellow, 2/-. 
O. CAMAMCllICA. Joints round, purple tinged, upper h.alf very spiny, flowers yellow, fruit large, 
pear-shaped, reddish-|iurple. Spines mostly light coloured, contrasting well with the com- 
paratively dark joints, i /6. 
O. FRAGIHS. A curious sort with small spiny joints, which break off easily, hence the name. It 
is a neat little plant, making a strong contrast when planted with the harger species, 2/6. 
O. MESACANTIIA GREENII. joints large, dark green, round, with a few greyish spine.s, mostly 
near the edge ; very free bloomer, fruit bright purple, remaining usually upon the plant till 
winter, 3/6. 
O. MESACANTIIA MACRORIIIZA. Joints smaller oblong, nearly spineless, usually s|wcading 
flat upon the ground ; light green. Flowers light yellow, fruit dull brownish green, very 
free bloomer ; the roots on old plants become much enlarged and tuber-like, 3/6. 
(). MESACANTIIA CYMOCHILA. Joints obovate, very glaucus, upper half well supplied with 
very long and stout spines which are reddish brown, usually beautifully mottled, and 
freijucntly more than two inches long. A most profuse bloomer, the yellow flowers followed 
by (|uantities of brilliant fruit. This is a favourite sort, 3/6 
O. PII/ICACANTIIA MAJOR. This we consider the mo.st beautiful of the Opuntias. The joints 
are very large, often 10 or 12 inches long, rather thin, heavily glaucus and usually with a vpy 
distinct purple tinge. The plant is a rapid grower, and in time forms immense clumps, whicn 
are quite symmetrical, and are very conspicuous as well as highly ornamental. The flowers 
arc exceedingly abundant, very deep yellow, smaller than those of the mesiicantha group. 
Spinesdark coloured, rather short and stiff, distributed over the entire joint. F'ruit Crimson, 3/6 
(), I’H.'FIACANTIIA x PoLyCANTIIA. A very interesting natural hybrid between these two 
distinct species, showing about equally the characters of both. A very beautiful plant, and 
offered lor the first time, 3/6. 
0. POLYCANTIIA. This is the hedgehog among Opuntias, with its long stiff spines so thickly set .as 
to hide arts of the phant. The spine.s are grey, yellow, light brown and dark purpli.sh 
brown, often several shades occurring on the same plant. The spines vary much in length 
and arrangement, so that no two plants are alike. F'lowers yellow or orange, fruit spiny, 1/6. 
O. POLYCANTIIA ALBLSPINA. A variety with pure white spines, which arc u.sually .>.lencler, 
and those on the old joints frequently become much elongated and curled or twisted. P lowers 
light yellow. A very handsome plant. 2/6. 
O. RAFINESQUEI. It has become an established favourite in gardens, as when in flower its beauty 
is amply suflicient to recommend the plant to the most fastidious, 1/6. 
O. RAFINESQUEI ARKANSA. Flowers large, measuring about 34 inches .across, light yellow, 
with a glassy co.ating of bright chamois in the centre, appearing in profusion in June and 
)uly, I/-
