long, curved upwards, the mouth oblique. Calya-tube funnel- 
shaped, the scales remote, subulate, appressed, lower ones ciliated 
with white hairs. Petals small, scarcely longer than the teeth of 
the calyx, deep yellow, acute. Stamens lying against the upper 
side of the tube, and there much longer than the flower: lower 
ones scarcely protruded. Anthers deep purple. W. J. 7. 
Curr. A pretty species of Cereus, of an erect, stiff habit, 
and apparently not of tall stature, having produced its flowers 
when less than two feet high. It grows freely in a soil com- 
posed of light loam, leaf-mould, and sand, care being taken that 
it be not retentive of water. The pot should be well drained, 
and the mould must never continue long saturated. ‘The latter 
precaution is especially to be observed in winter, for during that 
season the plant requires little or no water. We are not 
acquainted with its native locality, but judging from the climate 
of Buenos Ayres, we may suppose that it endures great ex- 
tremes of temperature, and often long droughts ; the thermometer 
in summer sometimes rising to 94°, and in winter falling so low 
as 36°; the mean temperature of summer and winter being 
respectively 72° and 54°. With us, a night temperature 
averaging 50° during the winter suits it; but in severe wea- 
ther it is not advisable to maintain that heat, for the plant 
does not suffer even when the thermometer is 10 to 15 degrees 
lower. When this is the case, however, it is desirable that a 
corresponding rise be maintained during the day. As the 
warmth of spring increases, the plant should be moderately 
supplied with water. In summer it should be allowed to receive 
the full power of the sun, with occasional syringeing over head : 
this operation must be performed after the heat of the day has 
declined, or early in the morning. J. S.

(In our last number, under Celogyne Wallichii (Tan. 4496.), we spoke, 
from memory only, of the extreme beauty of that plant at Chatsworth, Mr. 
Paxton has been so obliging as to inform us, it consisted of “eight pseudo- 
bulbs, which bore twenty-eight flowers: three of the pseudo-bulbs were large, 
three of a medium size, and two small. The three large ones each produced 
three flower-stems, and two out of three on each bulb were biflorous. Of the 
three medium-sized ones, one had four flower-stems, and the other two had 
three ‘stems each, all single-flowered. One of the two small bulbs bore two 
flowers on the stems, and the other bulb was single-flowered.”]
