Ord. XXVII. SAMYDE^E. Vent. 



1. Casearia corymbosa. H. B. K. — Hab. Acapulco. 



Ord. XXVIII. TEREBINTHACE^. 



I. Rhus terebinthifolia. Schlecht. in Linn. 5. p. 600. 



Torus a five-crenated disk. Stamens 5, inserted under its margin. Petals 5, broad at the base, inserted 

 under the disk. Sepals 5. Styles 3. 



2. R. aromatica. Ait. — var. foliis subtus dense fulvo-tomentosis. 



This diners in no respect from the species found in the United States and Canada, except in the leaves 

 being much more tomentose and occasionally wrinkled. Rafinesque, De Candolle, and most botanists, place 

 this and R. suaveolens in a distinct section, Clibadium, on account of there being supposed to be 2-lobed 

 glands placed under the ovary, alternating with the stamens ; but such is not the case : the torus or disk is 

 orbicular, with 10 crenatures, two of which are between each pair of stamens, and have been mistaken for 

 glands. The petals are slightly hairy on the inside, as in many Sapindacew, and indeed the whole plant 

 bears no small resemblance to Sckmidelia. There is one simple but very deeply trifid style, not three short 

 styles as usually described. 



1. Elaphrium Jacquinianum ; ramulis teretibus superne ferrugineo-tomentosis, foholis 

 7-9 grosse crenatis supra rugulosis hirtellis et nitidulis subtus molliter fuscescenti-tomen- 

 tosis junioribus ferrugineis terminali subrhombeo-ovato, lateralibus inasquilateris, rachi 

 alata, alis integerrimis. Humb. et Kunth, Nov. Gen. v. 7. p. 23. t. 613.— Fagara octandra. 

 L. ?— Elaphrium tomentosum. Jacq. Am. t. 71 ?—j3; glabrius, rachidis ala saspe crenata. 



The figure above quoted is so faithful a representation of our plant, in every particular except the entire 

 wing of "the rachis, that we are not disposed to separate it from that species. Our specimens being very 

 much advanced will account for the less tomentose foliage. 



Ord. XXIX. LEGUMINOS^E. Juss. 



1. Sophora tomentosa. L. 



1. Crotalaria ovalis ; tota molliter hirsuta diffusa, stipulis acuminatisdecurrentibus vel 

 obsoletis, foliis simplicibus ovalibus subsessilibus, pedunculis elongatis oppositifoliis 4-6- 

 floris, calycibus bibracteolatis vexillo vix brevioribus. (Hook, in Bot. Mag. t. 3006.) 

 Pursh, Am. Sept. v. 2. p. 469.— C. sagittal is, y, ovalifolia. Mich. 



This exactly agrees with the C ovalis figured in the Botanical Magazine, and which was raised from 

 Mexican seeds. 



2 C. sagittalis. L. 



3. C. dichotoma ; fruticosa diffusa, foliis ternatis cuneato-ellipticis pilosiusculis mucro- 

 natis, stipulis subulatis reflexis persist'entibus, racemis oppositifoliis paucifloris. Grah. in 

 Bot. Mag. t. 2714.— (3; foliolis angustioribus longioribus.— Hab. ft Talisco.
