near creek, July 8, 1900. 



I022. Scleria triglomerata Michx. 



Terra Cotta swamp, June 29, 189G. Seen since in Kenilworth swamp, 

 on Fairfax road south of Four J\Iile Run, and at Lakeland. 

 *io24Z*. Scleria reticularis pubescens Britlon. 



Paint Branch swamps and north of Kenilworth. t)ther material from 

 the Brightwood swamp (August 16 and September 22, 1897) with thicker 

 culms and broader lea\ e;; may be S. Torreyann "Walp. Thus far I find 

 it very difficult to separate these species. 



1024. Scleria pauciflora Muhl. 



Addison Heights, C'lievy Chase, Glen Echo Heights, Anacostia road 

 north of Kenilworth. Takoma Park, and Lakeland. 



1090. Carex lupulina Muhl. 



I have a form from the woods bordering the river marsh at l^ennings 

 determined by Professor Wheeler as "the variety near var. peduiiculata 

 Dewey". The peduncle of the sterile head is over 3 inches long. 

 1094. Carex bullata Schk. 



Formerly in the Brightwood Park swamp: common in the swamps 

 around Hyatts\ille. 



*io88(^ Carex lurida exundans Bailey. 



Very common. A form from the Potomac flats has some of the 

 staminate heads fertile at the summit. 

 1087. Carex hystricina Muhl. 



Canal at District line, May 28, 1897. Not common. 

 1085. Carex comosa Boott. 



I failed to distinguish this from C. pseudo-cyperus until last season, 

 but specimens from the Potomac flats seem decisive. 

 i092rt. Carex typhinoides Schwein. 



Lakeland, between the electric and steam railroad tracks, August 4, 

 1900. 

 1084. Carex riparia Curtis. 



Seen by me only in the river marsh east of the Alexander Island race 

 covirse. 

 105 1. Carex Shortiana Dewey. 



A few specimens in the Feeder Dam region, 1890. Abundant on the 

 Potomac flats west of the Fish ponds, 1900. 

 *i05irt. Carex lanuginosa Michx. 



Feeder Dam, May 21, 1898; river swamp, Alexander's Island, May 12, 

 1900. 

 *i048rt. Carex stricta angustata (Boott) Bailey. 



Margin of bay, foot of seventeenth street. May 18, 1898; also north of 

 Berwyn. This is not to be confounded with the C. angustata of Ward's 

 catalogue, which is doubtless the typical C. strkta. 



*io5i^>. Carex fusca All. 



Bog one mile north of Berwyn, May and Jul}- 28, 1900.
