Ord. XXXVI. BORAGINE.E. Juss. 



1. Cordia (Gerascanthus) tomentosa. Cham, in Linncea, 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 we 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. ACANTHACE^. Juss. 



1. Aphelandra cristata. Br. in Bot. Mag. p. 1578 — Justicia cristata. Jacq. 

 Hab. Acapulco. 



Ord. XXXVIII. VERBENACEjE. Juss. 



1. Lippia asperifolia. Rich. — Hook. Bot. Miscell. v. 2. p. 236. 

 Hab. Realcjo. 



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-lanceolatis serratis rigidis supra 

 scaberrimis subtus puberulis, floralibus parvis subovatis acutissimis, capitulis paucifloris 

 densis subsessilibus, in racemum terminalem interruptum subramosum 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.
