collected the following spring. This plant greatly resembles Conium 

 maculatum in general appearance. It seeds freely, and the seeds spring 

 \\\) abundantly aroiind the old plant, but it does not appear to increase 

 much. 



338a. Scandix pecten=Veneris L. 



Dumping place near propagating grounds May 3, 189S: also on Massa- 

 chusetts Avenue extended. 

 331a. Conium macu!itum T.. 



Rock Creek ravine near M street bridge. July 11, 181)8; \ery abundant 

 during that and the following season. Also on waste ground near Mr- 

 ginia Avenue, and on dumping ground at New-cut Road. 



""340rt. Carum Carui L. 



Two plants were collected on the river-front dumping groinid in 181)8. 

 356a. Cornus circinata LHer. 



A si^ecimen of this species was brought by a lady to the Department 

 of Agriculture from Takoma Park in 1899. 



563fr Clethra ainifoiia L. 



One of the Paint Branch swamps, September 23, 1899; Berwyn, July 

 28, 1900; also at another point north of Berwyn, and in considerable 

 iiuantil>- near the creek at Lakeland. This fine shrub can therefore be 

 considered as definitel}' belonging to our flora. 



""557'f- Azalea viscosa hispida (Pursh) Britton. (?) 



A plant was found in sphagnous ground south of Four Mile Run, also 

 one atXauck's, agreeing exactly with some local specimens of A. viscosa 

 (jltnaui, except that the flowers were of a rich flesh color instead of pure 

 white. This suggests variety hispida; but the specimens .seen were of 

 low stature, and the laedicels were not more hispid than those of some 

 specimens of ylavca. 



1 am of the opinion that the plant which has passed as variety nitida 

 here is only a state of variety iilannt. This is not to say that there is 

 not a true nitida elsewiiere. 



556. Kalmia angustifolia L. 



One of the Paint Branch swamps. September 3, 1900, in fruit. 

 554. Leucothoe racemosa (L.) A. Gray. 



The best stations I have found for this plant are: Bennings near the 

 railroad, and flats opposite Alexandria near the bluffs. 

 *544o. Gaylussacia dumosa hirtella (Ait.) A. Gray. 



South of the electric road junction, Takoma Park, Jvme 7, 1897. First 

 noticed by Mr. T. H. Kearney on the same occasion. I have not found 

 this plant since. 



*544('>. Vaccinium atrococcum (A. (iray) Heller. 



Bennings, April 13, in flower; Kenilworth swamp, May 10 and June 

 13; in ripe fruit, 1898. 



575. Lysimachia quadrifolia L. 



The form with all the leaves opposite was found at Lakeland, July 8, 

 1900, and seemed to be common.
