20 Crossville: Panicum triplex, a rare species, also found in the oak barrens. Linum intercursum Bicknell, differs from L. floridum in the acuminate sepals. L. virginicum is the commonest species around N. York; L. strictum (recently after is next). Sarcocaulon Smellii, same achenes as Dakota Co. Mttingham various material. Jan. 29 (Wednesday). Continued Ann. Rept. Dr. Gage Brushel visits herbarium. Looked over Hypericum in herbarium. It would be a good genus to monograph for N. Am. Returned E. nigriscens to Dr. Seward Feb. 6 (Thursday), Hieracium: The most frequent species in an area seems to be H. scabrum, although H. canadense appears in the northern part of Long Island. H. Gronovii is represented on the coastal plain chiefly by var. foliosum. H. marianum is a doubtful species, probably represented by one of the other species. Feb. 7 (Friday). Continued Hieracium. H. marianum is to be differentiated by Dr. Endromus. It has a hairy stem (not so dense as in H. scabrum, which it resembles in form) and is related to H. Gronovii. The bifrequency is divaricate, and the achenes columnar. It is either H. Gronovii var. foliosum, or an aberrant H. venosum with somewhat hairy peduncles. A group of Local species: H. canadense - large heads, columnar achenes, toothed lvs. H. scabrum - very hairy, thick peduncles, columnar achenes, H. penicillatum - smooth with toothed leaves. H. Gronovii - los. with bilobate brachomes, heads small, peduncles thin but hairy.
