Hab. Between San Bias and Tepic. — Better specimens in Dr Sinclair’s collection, than we before pos- 
sessed, have satisfied us that we were wrong in referring this to De Candolle’s Tithonia pachycephala. It 
is quite a different and a frutescent species.

Hab. Between San Bias and Tepic. 
2. L. macrocephala (n. sp.) ; foliis rigidis subsessilibus ellipticis acutissimis serratis

ovato-subrotundis interioribus ellipticis apice scariosis infra apicem constrictis, acheniis 
centralibus aristis 2 elongatis. 
Hab. Between San Bias and Tepic. — A solitary specimen of this is in the collection. Leaves 3-4 inches 
long, harsh and rigid, with very short inconspicuous hairs. Capitula 5 or 6 times as large as in L. umhellata. 
Our Verbesina ? ceanothifolia, supra, p. 299, is undoubtedly a congener with this. \

Hab. Between San Bias and Tepic. — A fine handsome species, allied to C. cordifolia, but quite distinct 
in its entirely sessile leaves. 
2. C. cirsiifolia (n. sp. Sect. Eucacalia); erecta, glabra, caule herbaceo superne suba- 
phyllo, foliis inferioribus lanceolatis pinnatifidis laciniis patentibus lineari-oblongis acutis
