all reflexed, three of them ovate, the others lanceolate. 
Nectariferous tube unequal in length, from 3 to 4 times 
as long as the calyx, flattened on both sides, and thickly 
clothed with spreading hairs. Petals 5, all broadly wedge- 
shaped, at first spreading, afterwards reflexed, of a dark 
velvetty purple, edged with light purple, upper ones about 
half as broad again as the lower ones, and lighter at the 
base. Filaments 10, united into a short tube, 6 only bear¬ 
ing anthers, which are very imperfect, besides those is a very 
broad spathulate one, as in the others of the section; it 
therefore belongs to the section Monospatalla, and not 
to Polyactium, as might be supposed from its habit. Style 
quite smooth and naked. Stigmas 5, reflexed. 
The present curious plant is of hybrid origin, and was 
raised at the Nursery of Mr. Colvill, from a seed of P. mul- 
tiradiatum , that had been fertilized by the pollen of P. 
triste, and it is as near as possible intermediate between 
the two; the habit of the plant partakes chiefly after the 
former parent, but the character of the flowers is precisely 
that of the latter; like both of its parents, the flowers are 
sweet-scented at night, but without scent during the day; 
this, as well as the other succulent and tuberous-rooted 
sorts, succeeds well in an equal mixture of light turfy loam, 
peat, and sand, and is readily increased by the tubers from 
its roots; those must be planted with their points above the 
surface of the mould, and should have no water given them 
before the wound is dried over; they may afterwards be 
watered regularly when dry, and they will soon make nice 
young plants.
