a half or two inches, erect, straight, or somewhat flexuose, 
of nearly the same width throughout, obtuse at the extre- 
mity, marked with eight to ten prominent, rather acute 
angles or ridges, which are beset with little tufts of rather 
long, lax, and deciduous wool, whence arises a spreading 
(or when young erect) cluster of dingy brown, long, slender, 
and sharp aculei, some of them nearly an inch m length, 
longer than the wool. From a tuft of this description (the 
woolly substance being increased in quantity, and rising 
one above another in each successive season,) springs a 
flower, large, indeed, in proportion to the size of the plant, 
but not remarkable for the beauty of its colour. The tube 
is about two inches long and three-fourths of an inch thick, 
of an olive green colour, glabrous and unarmed, expanding 
upwards into many imbricated, fleshy scales or segments, 
which are ovate and acute, often tinged with rose colour. 
These may be considered as constituting the calyx: for 
within is a series of ovate, pale rose-coloured petals, shorter 
than the calyx. Stamens numerous, shorter than the co- | 
rolla. Anthers linear-oblong, pale yellowish-white. Style — 
exserted, white, jointed near the base, and deep rose colour- 
ed below the joit. Stigma of about seven or eight rays, 
which are erect, or connivent, white. 
_ The difficulty of determining the various species of the 
Cactus tribe, is well known to those who have had occasion 
to study them. In the present instance, we have given @ 
plate of an individual, which certainly, in description, is so 
little at variance with the Cereus Royeni, that I am inclined 
to think it is that species: although the exterior scales of 
the flower are not acuminated, as De Canpoue describes 
them to be ; nor are the petals white, but rose-coloured. 
Our specimens were obligingly communicated to the 
Glasgow Botanic Garden by —— Rysurn, Esq. of this 
place, who received them from Mr. Swarr of Grenada. — 
Our tallest plant, three feet and more in height, flowers 
readily in the spring and summer. We possess a very 
similar plant from Trinidad, whence it was sent by the 
late Baron de Snack: but it has considerably shorter 
poe, and is, probably, the Cerrus lanuginosus of Mr. 
Awortu (Cactus lanuginosus. Lan.) )
