MEXICO.— SUPPLEMENT. 



[ Composites. 



capitulis multifloris, involucri squamis striatis nitidis imbricatis exterioribus lanceolato- 

 interioribus longioribus angustissimo-linearibus, corolla? perangustoe lobis brevissimis 

 obtusis, pappo aequali e setis tenuibus fuscis 12-14 corollae longitudinem sequante. 



Hab. Acapulco. — Whether of the genus Phania of De Candolle or not, it is doubtless a congener with 

 our Phania? urenifolia, supra, p. 297. The habit is quite the same, and the involucre and corolla: the 

 leaves however and the pappus are extremely different. 



1. Stevia elliptica (n. sp.) ; pubescenti-glandulosa superne prsecipue, foliis oppositis 

 ellipticis seu ovato-ellipticis serratis trinerviis basi brevi-attenuatis sessilibus, capitulis 

 glomeratis corymboso-paniculatis, pappi setis 3-4 asperis longitudine corollas. 



Hab. Between San Bias and Tepic. — A tall growing shrubby plant with a good deal the appearance of 

 Stevia trachelioidcs, DC. and Hook. Bot. Mag. t. 3856: — but the pappus is extremely different, having 

 no palete and only from 3 to 4 long scabrous seta?. It has not enough of setffi to range with De Candolle's 

 Div. Multiaristata. 



2. Hebeclinium Tepicanum (n. sp.) ; fructicosum, glabrum, foliis membranaceis ovato- 

 lanceolatis acuminatis petiolatis pellucido-punctatis serratis, panicula terminali thyrsoidea, 

 capitulis parvis subquinquefloris, involucri imbricati squamis ellipticis obtusis striatis, 

 acbeniis obovatis angulatis, pappi setis sub-20 corollas longitudine apicibus clavellatis 

 plumosis. 



Hab. Between San Bias and Tepic. — The general aspect of this plant is very similar to that of the well 

 known //. macrophyllum, but the branches are woody to the very apices, as in Mr Bentham's H. macro- 

 cephalum. The leaves are nearly a span long, copiously pellucido-punctate, the involucres and the size of 

 the capitula are as in the former mentioned species. 



1. Erigeron velutipes (n. sp.) ; annuum parvum pubescens, caule erecto superne pani- 

 culato basi pilis albis patentibus dense vestito, foliis acutis inferioribus spatbulatis grosse 

 inciso-serratis superioribus linearibus integerrimis, pedunculis elongatis parce pilosis 

 monocephalis, involucri hemisphserici squamis linearibus scarioso-marginatis, ligulis 

 copiosis disco duplo longioribus. 



Hab. Between San Bias and Tepic. — This may be placed near E. scaposum, DC. n. 27, but the stem 

 is always branched or panicled even in the smallest specimens, and the base of the stem and attenuated 

 bases of the lower leaves are densely clothed with long white hairs. 



J. Chrysopsis? scabra (n. sp.) ; annua gracilis erecta superne paniculata, foliis inte- 

 gerrimis acutissimis radicalibus spathulatis caulinisque oppositis lanceolatis summis 

 linearibus subulatisve bracteiformibus, involucri squamis linearibus pubescenti-hirsutis, 

 ligulis sub-1 2 disco duplo longioribus, pappi simplicis seriei setis 3-5 scabridis longitudine 

 fere tubi basi dilatato-paleaceis. 



Hab. Between San Bias and Tepic An annual, herbaceous plant, 1 foot to l£ foot high ; the leaves, 



except those of the panicle, are opposite (!) and the pappus certainly is not double ; so that though it has the
