Description of the Species, Siphocampylus revolutus. 
Stem erect, round, sparingly branched, branches zigzag, villous, green. 
Leaves alternate, on short stout channelled petioles, rigid, wrinkled, 
spreading wide, dark green and rough, with very short hairs above, 
lighter and villous below, cordato-ovato, acuminate, the apex of the 
upper ones revolute, the edges reflexed, simply dentate; middle rib 
and veins very prominent below, channelled above. Peduncles soli¬ 
tary, axillary, erect, half as long as the leaves, villous, without bracts. 
Calyx green, villous; tube turbinato-hemispherical, with 10 strong ribs, 
and as many round glands between the apices of these ; limb 5-partite, 
segments twice as long as the tube, subulate, diverging at the apex. 
Corolla five times as long as the calyx, purplish red; tube entire, 
slightly deflexed, contracted at the throat, and for a space equal to the 
length of the calyx segments at the base, where it is deeply marked by 
five grooves, in the centre inflated and compressed laterally ; limb five 
partite, segments subequal, linear-lanceolate, acute, slightly hairy 
within, the two upper straight and paler within, the lateral ones spread¬ 
ing or reflexed, slightly falcate downwards, the lowest revolute, and, 
as well as the lateral ones, nearly white. Stamens as long as the 
corolla; filaments inserted along with this into the top of the calyx, 
adhering to the tube as far up as the extent of the contracted portion at 
the base, above this uniting into a tube, red and glabrous; anthers 
lead-coloured, cohering into a curved tube, the two lower bearded 
with white hairs at the apex, the three upper having a very few 
similar hairs in their commisures. Style encased by the stamens, 
projecting beyond the anthers, glabrous, red. Stigma of two blunt, 
revolute lobes. Germen inferior, green, glabrous, and with a free 
conical apex, bilocular. Ovules very numerous, small, on large 
central placentae. 
Popular and Geographical Notice. This beautiful genus is 
entirely American, and scarcely passes without the tropics, but is found 
on both sides of the line. I do not know from what part the seeds of 
the present species were introduced. It is a true example of the 
genus, and altogether unlike the plants known in cultivation as Sipho¬ 
campylus bicolor (t. 139) and S. Cavanillesii (t. 234), which are true 
Lobelias. 
Introduction; Where grown; Culture. Seedling plants were 
received at the garden of the Caledonian Horticultural Society, from 
Mr. Low, of Clapton, in September, 1839. They grew to the height of 
five feet last year, in the stove, without flowering; cuttings were formed, 
these rooted readily, and, when of a small size, flowered in February, 
1841. We possess the plant at the Botanic Garden, also from Mr. Low. 
It is kept in the Greenhouse, and is very healthy, but has not yet come 
into flower. It requires no particular soil or treatment. 
Derivation of the Names. 
SiPHOCAMPYLCs, from (Ti^wp a tube, and KajuTTyXog curved, in allusion to the 
bent tube of the corolla. Grah.
