Ord. XXXVI. BORAGINE^. Juss. 
1. Cordia (Gerascanthus) tomentom. Cham, in Linnoea, v. 4. p. 472. 
Hab. Between San Bias and Tepic. — This exactly agrees with authentic specimens of C. tomentosa from 
tropical Brazil in our Herbarium. The species is at once distinguished from G. Gerascanthus, nobis (supra, 
p. 304,) which vre believe to be the true plant of Jacquin, by the larger, more acute leaves, less tapering^ at 
the base, clothed beneath with stellated pubescence, by the smaller' flowers and shorter calyx, in proportion to 
its size. 
2. C. (Varronia) multispicata. Cham, et Schlecht. in Linncea, 4. p. 490. 
Hab. Between San Bias and Tepic. — This differs in no respect from our authentic specimen from the 
Berlin Herbarium, except in the leaves being of a thinner and more membranaceous character. 
Ord. XXXVII. ACANTHACEiE. Juss. 
1. Aphelandra cmtote. Br. in Bot. Mag. p. 1578 Justicia cristata. Jacq. 
Hab. Acapulco. 
Ord. XXXVIII. VERBENACEtE. Juss. 
1. Lippia asperifolia. Rich. — Hook. Bot. Miscell. v. 2. p. 236. 
Hab. Realejo. 
2. L. geminata. H.B.K. Nov. Gen. Am. 2. p. 266. 
Hab. Realejo. — This seems to agree with the L. geminata, H.B.K. except that the leaves are more 
generally obtuse than acute. — It is also nearly allied to L. microphylla, Cham, et Schlecht.: -but there the 
leaves are smaller, more harsh and wrinkled, and the scales of the capitula are acuminated. 
Ord. XXXIX. LABIATE. Juss. 
1. Hyptis (Polydesmia) rhytidea (Benth. PI. Hartweg. p. 21.); fruticosa, ramis glan- 
duloso-pubescentibus, foliis breviter petiolatis oblongo-Ianceolatis serratis rigidis supra 
scaberrimis subtus puberulis, floralibus parvis subovatis acutissimis, capitulis paucifloris 
densis subsessilibus, in racemum terminalem interruptum subramosutn dispositis, bracteis 
paucis oblongo-linearibus subulatisve calyce plerumque brevioribus, calycibus pubescen- 
tibus subviscosis, fructiferis acutis obliquis rigidis, dentibus lanceolato-subulatis sub- 
spinescentibus, corolla calyce parum longiore leviter pubescente. Benth.
