shorter than the calyx. Sepaxs unequal, broadly lanceolate at the 
base, ending gradually in a long point, clothed on the outside towards 
the base with long soft hairs, nearly smooth towards the point, the 
outer longest, sepals about three quarters of an inch, the innermost 
little more than half an inch long. Coroxua above two inches long, 
narrow, bell-shaped, or broadly funnel-shaped, smooth, the tube ample, 
the limb spreading, folded, five-angled. ‘STAMENS unequal in length, 
inserted near the base of the tube, filaments dilated at their insertion, 
furnished with long hairs immediately above, smooth and filiform in 
the upper half. Ovary three-celled, surrounded by a cup-shaped

-Poputar aND GeocrapHican Notice. The plant long since 
known to gardeners under the name of Convolvulus major, and to bot- 
anists as Ipomeea purpurea, together with Ipomeea nil, and some other 
species, had long since been observed to differ, in many respects, both 
from Convolvulus and Ipomeea, and Choisy, in the revision of the 
order (which will be further noticed under Jacquemontia pentantha) 
established them as a genus, one of the easiest defined in its botanical 
character, being the only one with more than four ovules to the ovary, or 
seeds to the capsule, It may also be known by the habit, and contains 
so many ornamental species, that Choisy gave a name which alludes to 
richness of colour. This name is fully justified by the new species we 
have now to add, one of the few inmates of the tropical regions of the 
older hemisphere, the greater number of species belonging to tropical 
America. 
InTRODUCTION; WHERE GROWN; CuLTuRE. This beautiful spe- 
cies was discovered in Ceylon by M. Lear, collector to Mr. Knight, of 
‘the King’s Road, and by him sent over to that rich establishment. It 
was there first raised in 1839, and named Ipomeea Learii, after its dis- 
coverer, a name which we have with pleasure adopted in transferring 
it to its right genus. The specimen from which our drawing was made, 
‘begun with bearing twenty blossoms, and at the time it was drawn, 
there were two hundred and thirty out at once. Mr. Williams’s method 
of taking cuttings with a leaf and portion of the old stem, will be appli- 
cable to this plant, Vol. 1, No. 31.
