78 Steele Additions to the Flora of Washington. 



648a. Capsicum sp. 



A single plant was found in the last-mentioned locality; it was taken 

 home and replanted, and bore fruit of a conical form. 

 *6486. Petunia violacea Lindl. 



A purple petunia, doubtless of this species, appears occasionally on 

 the dumping grounds. 

 *662a. Gratiola sphaerocarpa Ell. 



Pond near Bladensburg pike, May 17, 1898; ditch at Lakeland, Md., 

 August 4, 1900; scarce. 

 *662a. Gratiola viscosa Schwein. 



Eastern Branch swamp south of Bennings road, August 29, 1899; M 

 street extended, September 10, 1899: mouth of Beaver Dam Branch, 

 August 11, 1900. Abundant, especially in the last locality. 

 663. Ilysanthes attenuata (Muhl.) Small. 



Jackson City, August 1, 1899; Bennings, August 29, 1899, less common 

 than /. gratwloidex. Though on young stems of gratioloides the peduncles 

 scarcely exceed the leaves and though on old branches of attenuata the 

 peduncles may exceed them, on the whole the peduncles of the former 

 are much longer, sometimes a full inch in length. In my specimens the 

 leaves of attenuata are larger, and it has a much greater tendency to 

 root at the nodes. 



664. Micranthemum micranthemoides (Nutt.) Wetlst. (J/. Nuttallii 

 of Ward's Catalogue). 



Still growing at Hunting Creek, September 4, 1899. 

 667. Veronica scutellata L. 



Feeder Dam, July 22, 1897. 

 679. Pedicularis lanceolata Michx. 



Still found at Hunting Creek, September 4, 1899, at that date just 

 coming into flower. 

 686a. Utricularia subulata L. 



Howard Hill reservoir, abundant, May 22, 1899. 

 *6866. Utricularia biflora Lam. 



Specimens collected on the flats at Chain Bridge, August 16, 1899 and 

 August 1, 1900, seem to belong to this species, and an earlier collection 

 near the Second lock is perhaps the same. If this determination is cor 

 rect it would throw some doubt upon the existence of U. gibba recorded 

 in Ward's Flora, although of course it is possible we have both. 

 *688a. Catalpa Kaempferi Sieb. & Zucc. 



A tree determined by Mr. Geo. B. Sudworth as a hybrid of this species 

 stands near Virginia Avenue and Eighteenth street, appearing as if 

 spontaneous. 

 *6p2a. Martynia Louisiana Mill. 



Dumping ground, river front, August 22, 1900, a single plant; in fruit 

 later. Flowers rather small and numerous; perhaps not this species. 

 691. Ruellia strepens L. 



A remarkable plant perhaps belonging to this species was collected
