648(1. Capsicum sp. 



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

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



*648b. Petunia violacea I^indl. 



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

 the dumpino- grounds. 



*662fl. Gratiola sphaerocarpa Kll. 



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

 August 4, 1900: scarce. 



*662a. Gratiola viscosa Schwein. 



Eastern Branch swamp south of i^ennings road, August 29, 1899; M 

 street extended, September 1(), 1899; mouth of Heaver Dam Branch, 

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



663a. Ilysanthes attenuata (Muhl.) Small. 



Jackson ('ity, August 1, 18i)9: Bennings, August 29, 1899, less common 

 than /. f/ratioloidex. Though on young stems of gratioloides the pedvincles 

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

 peduncles luay e.vceed them, on the whole the peduncles of the former 

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

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

 root at the nodes. 



664. Micranthemum micranthemoides (Xull.) Wettst. (M. Wuftdltii 

 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 

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

 near the Second lock is perhaps the same, li this determination is cor- 

 rect it wovild 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. 



*6gia. Martynia Louisiana Mill. 



Dumping ground, ri\er front, August 22, 1900, a single plant; in fruit 

 later. Flowers rather small anil numei'ous; perhaps not this species. 

 691. Ruellia strepens fj. 



A remai'kable plant perhaps belonging to this species was collected
