1921] Fernald,— Expedition to Nova Scotia 235 



C. scoparia, var. subturbinata Fernald & Wiegand, Rhodora, 

 xiv. 116 (1912). Collected by us at one of the original stations, 

 Meteghan; also at Deerfield, Yarmouth Co. 



** C. scoparia, var. tessellata Fernald & Wiegand, Rhodora, 

 xi'i. 135 (1910). Wet sandy and gravelly swales and roadsides, 

 Belleville, Yarmouth Co. (scales almost black, darker than in the 

 original material). 



* C. Crawfordii Fernald. Swales and damp peaty barrens, 

 Cumberland Co. to Cape Breton, west to Annapolis and Queens Cos. 



C. projecta Mackenzie. C. tribuhides, var. reducta Bailey. 

 Meadows and damp thickets, apparently throughout the province. 

 This includes the Nova Scotia material recorded by Macoun as C. 

 cristata. 



* C. albolutescens Schwein., var. cumulata Bailey. Dry or 

 moist open barrens, frequent from Yarmouth to Lunenburg and 

 Cumberland Cos., thence into New Brunswick and Prince Edward 

 Island. Perhaps specifically distinct. See pp. 132, 138, 150. Or- 

 dinarily, the round-based spikes are densely crowded but in one col- 

 lection (no. 20,311 from Broad River, Queens) a single tuft shows 

 both crowded and moniliform inflorescences; the latter 1 dm. long, 

 with 7 remote spikes. 



** C. albolutescens var. cumulata x scoparia, n. hybr., C. sco- 

 pariam simulans, sed foliis latioribus; spicis brunneis late obovoideis 

 apice truncatis; perigyniis ovatis vel obovatis plerumque vacuis. 



Similar to C. scoparia but with broader leaves: spikes brown, 

 broadly obovoid, truncate at summit: perigynia ovate or obovate, 

 mostly empty.— Nova Scotia: with the parents but more abundant 

 than either, damp Polytrie hum -covered sandy plains, Middleton, 

 Annapolis Co., July 20, 1920, Fernald, Pease & Long, no. 20,327 

 (type in Gray Herb.). See p. 138. 



**C. straminea Willd. Rare. Yarmouth Co.: low woods 

 and thickets by Butler's (Gavelton) Lake, Gavelton. Shf.lburne 

 Co.: thicket bordering salt marsh, Villagedale; moist Poh/trichum- 

 covered barrens near Clement Pond, Barrington. 



This is C. straminea as interpreted by Mackenzie (Bull. Torr. 

 Bot. CI. xlii. 605), a coastal plain species recognized by Mackenzie 

 as extending from Louisiana to southern New York. Subsequently, 

 Bicknell (Bull. Torr. Bot. CI. xliv. 377) has reported it from Nan- 

 tucket, Mr. F. C. Seymour has found it on Martha's Vineyard and 

 I have collected it in swampy thickets on Cape Cod. The plant 

 called C. straminea in Gray's Manual, ed. 7, is C. tenera Dewey. 



C. HOBMATHODES Fernald. Brackish or fresh marshes not far 

 Prom the sea, common throughout the province. Macoun's report 

 of C. straminea, var. j 'est ueaeea from Baddeek was based on material 

 of ('. hormathodes.
