MACLOSKIE: REVISION OF FLORA PATAGONICA. 263 



C. AUSTRALIS Phil. 



Dr. Reiche believes that this is Erigeron sylvaticus Phil. Cf. Reiche 

 Flor. Chil., iv, 365. 



HETEROTHALAMUS Less. 

 P. 800 : 



H. NIVALIS (Sch. Bip.) Wedd. 



Is found also in W. Patagonia, near Lago Argentino. D. 



BACCHARIS L. 



Dr. W. Heering has made the revision of this genus as far as the 

 incomplete material permits. D. 



P. 802 : 



B. BRYOIDES Pers. 



The plant certainly does not belong to the genus Baccharis ; Reiche 

 supposes it to be Melaleuca humifusa Hook. D. 



P. 803 : 



B. CHUBUTENSIS Speg. 



Delete this, as it is not specifically distinct from B. sagittalis DC. D. 



B. CONFERTA H.B.K. 



This Mexican species cannot be also in the Falklands. Probably the 

 specimen belongs to B. magellanica, which is the only one known in 

 these islands. 



B. CONFERTIFOLIA Colla. 



This should be deleted ; the specimen belongs probably to a form of 

 B. marginalis, which is closely allied to B. confertifolia. D. 



P. 803 : Insert : 



B. CYLINDRICA DC. 



Belonging to DeCandolle's section Cauloptercs, having leaves oblong, 

 linear, or none, the branches having leafy wings, decurrent on both sides 

 from the leaf-bases. Is herbaceous, 3-winged, the wings plane, veiny, 

 interrupted, and the leaves reduced to minute scales, the heads spicate, 

 closely glomerate, the involucres of the males campanulate, of the females
