19, 3 Merrill: Burman’s Flora Indica 375 
IPOMOEA 1Linnaeus 
IPOMOEA BATATAS (Linn.) Poir. in Lam. Encycl. 6 (1804) 14. 
Convolvulus batatas Linn. Sp. Pl. (1758) 154. 
Dioscorea cylindrica Burm. f. Fl. Ind. (1768) 215- (err. typ. 315). 
Burman’s species is typified by Kappa-kelengu Rheede Hort. 
Malabar. 7: t. 50, which clearly represents the common sweet 
potato. Hooker f., Fl. Brit. Ind. 6 (1892) 296, is in error in 
considering that Rheede’s figure represents some cucurbitaceous 
plant. There is no evidence that Burman had any botanical 
material for examination in proposing the binomial Dioscorea 
cylindrica. 
QUAMOCLIT Moench 
QUAMOCLIT SAGITTAEFOLIA (Burm. f.) Choisy in DC. Prodr. 9 (1845) 
335. 
Ipomoea sagittaefolia Burm. f. F]. Ind. (1768) 50, t. 18, f. 2. “Habitat 
in Java.” 
Ipomoea hastata Linn. Mant. 2 (1771) 204. 
Ipomoea phaenicea Roxb. Fl. Ind. 2 (1824) 92. 
Quamoclit phaenicea Choisy Conv. Or. (1834) 51. 
This is clearly a yellow-flowered form of Quamoclit phaenicea 
(Spreng.) Choisy, which is, however, not clearly distinguishable 
from Quamoclit coccinea (Linn.) Moench. 
ARGYREIA Loureiro 
ARGYREIA MOLLIS (Burm. f.) Choisy Conv. Or. (1834) 38. 
Convolvulus mollis Burm. f. Fl. Ind. (1768) 44, t. 17. “Habitat in 
Java.” 
Convolvulus sericeus Linn. Mant. 1 (1767) 43, non Argyreia sericea 
Dalz. & Gibs. 
Burman’s specific name is the proper one for this well-known 
Malayan species. It is suspected that both Burman’s and Lin- 
naeus’s descriptions were based on material of similar origin. 
ARGYREIA NERVOSA (Burm. f.) Bojer Hort. Maurit. (1837) 224. 
Convolvulus nervosus Burm. f. Fl. Ind. (1768) 48, t. 20, f.1. “Habitat 
Coromandeli.” 
Convolvulus speciosus Linn. f. Suppl. (1781) 137. 
Argyreia speciosa Sweet Hort. Brit. (1827) 289. 
Burman’s specific name should be retained for this well-known 
species, which commonly appears in botanical literature as Argy- 
reia speciosa Sweet.
