Philippines. 
The three gatherings from Perak agree with each other in every respect. They 
differ from the plant as it occurs in Tenasserim, in having a more widely urceolate- 
corolla and even longer and more lanceolate sepals ; at the same time they differ 
from the plant as it occurs in the Malay Archipelago, in having the sepals narrowly 
lanceolate and acuminate, instead of ovate and sub-acute. As regards corolla, 
however, they are exactly like the species as it occurs elsewhere in Malaya. Since 
the Perak plant combines the characters of the two previously recognised species — 
L. Wallichii with long acuminate sepals and L. flavescens with wide-urceolate corolla — 
it appears to afford conclusive proof of the suggestion already made by Clarke, l.c., 
that the Assamese and the Malayan plants are no more than forms of one somewhat 
variable species. An Indian form occurs in Travancore ; this has been characterised 
by Stapf as a distinct species, L. leiocalyx, probably quite justly, since the Travancore 
plant has quite glabrous and obtuse sepals : the same form occurs in Chittagong 
otherwise, however, the Indian plant agrees with the forms reported from Indo-China 
and Malaya. 
Ipomcea, Linn. 
Herbs, rarely shrubs, twining or prostrate, less often sub- erect or 
erect. Leaves alternate, entire lobed or divided. Floivers axillary, 
solitary or in cymes, the cymes rarely paniculate, or in terminal spikes ; 
bracts various. Sepals 5, ovate or linear, equal or unequal. Corolla 
campanulate or infundibuliform ; limb plicate, very slightly 5-lobed. 
Stamens 5, included or very rarely exserted ; filaments filiform or 
dilated at the base, often somewhat unequal ; anthers straight or con- 
torted ; pollen spinulose. Ovary 1-3-celled, rarely 4-celled ; ovules 4,. 
rarely 6 ; style filiform ; stigma capitate, entire or 2-3-globose, rarely 
stigmas 2, linear. Fruit a 4-6-valved capsule, rarely indehiscent. Seeds 
4, less often 6, rarely solitary, glabrous, bearded, or uniformly velvety 
or woolly. — Distrib. Species about 300, throughout the tropics.
