teate, but without coma, nearly sessile, and raising only its — 
upper surface above the water which the cup formed by 
the leaves contains. Bractee, one on the outside of each 
flower, ovate, convex internally, and somewhat cucullate, 
broadest on the outside of the capitulum, and there longer 
than the calyx, shorter than it in the centre. Flowers ex- 
pand in succession from without inwards, generally only 
one or two at atime, standing three-fourths of an inch above 
the surface of the capitulum. Calyx ovate, acuminate, 
green, glabrous, shining, segments overlapping, greatly 
dilated upon one side, which is scariose, transparent, and 
rT between the next segment and the corolla (ten and a 
alf lines long). Corolla (one inch four and a half lines 
long) three-parted, segments subequal, unguiculate, claws 
white, linear, glabrous, equal in length to the calyx (two 
and a quarter lines broad) erect, bearing on their inside at 
their base large, connate, smooth, shining, colourless, nec- 
tariferous glands ; limb spreading, segments ovate, acumi- 
nate, blue, slightly striated in the centre, and paler behind 
and towards the edits Stamens inserted at unequal heights 
into the claws, three into one, two into another, and one 
into the third; filaments flattened, similar in structure and 
colour to the claws of the corolla, inserted into the back of 
the anthers, and continued along these to their apices ; all- 
thers projecting into the throat of the corolla, of equal 
length, and approximating at their apices (nearly three 
lines long), white, acuminate, cleft from the base for about 
a quarter of their length, above which they are connate 
along the back with the filaments; pollen white. Pistil 
equal in height to the stamens ; stigmata three, flattened, - 
ciliated on one edge, spirally twisted ; styles three, united 
throughout their whole length ; germen inferior, glabrous, 
three-celled ; ovula very numerous, small, attached to @ 
central receptacle. ° 
This plant was brought to the Edinburgh Botanic Gat- 
den by Captain Granam, of H. M. Packet Service from Mr. 
Harris, at Rio Janeiro, in 1824, and has grown freely 2 
rich soil in the stove, pushing up three crowns from it8 
root, only one of which has yet flowered. Granam.
