1324 APPENDIX 



Page 189, after Stenophyllus coaretatus, insert: 



3a. Stenophyllus Cdrteri Britton. Leaves erect ; blades setaceous, ciliate ; 

 sheaths scarious: scapes tufted, 0.5 dm. tall, very slender: bracts of the involucre 

 mostly 3, one of them longer than the inflorescence; blades ciliate-serrulate : spikelets 

 numerous, in a terminal compound umbel, mainly ovoid, few-flowered: scales brown, 

 acute, ciliate-scabrous : achenes obovoid, about 0.5 mm. long, depressed at the apex, 

 minutely papillose, the tubercle very small. — Differs from S. coaretatus in the ciliate 

 leaf -blades, the ovoid spikelets and the small achene. 



In pine lands, southern peninsular Florida. Summer and fall. 



Page 192, at the end of the ninth line from the bottom of the page add "or 

 rarely larger." 



Page 195, after Eyncliospora Curtissii, insert: 



18a. Rynchospora fiisca (L.) Ait. f. Stems slender, 1.5-4.5 dm. tall, smooth: 



leaf -blades filiform-setaceous, channeled, shorter than the stems: spikelets fusiform, 



about 5 mm. long, acute, in 1-4 loose clusters; scales brown, shining: perianth-bristles 



6, often unequal, upwardly barbed: achenes narrowly obovoid, smooth, shining; 



tubercle triangular-subulate, nearly as long as the aehene-body. — Differs from B. 



Curtissii in the broad achene and the short bristles. 



In bogs and about pine-land ponds, New Brunswick to Michigan and Florida. Also 

 in Europe. Summer. 



Page 196, after HyncJwspora gracilenta, insert : 



22a. Rynchospora Sm^llii Britton. Stems relatively stout, 8-14 dm. tall, 



tufted: leaf -blades flat, 2-5 mm. wide: spikelets numerous in several rather loose 



clusters, fusiform, 3-4 mm. long; scales brown, lax, and deciduous at maturity: 



perianth-bristles upwardly barbed, as long as the achene and tubercle: achenes 



narrowly obovate, brown, smooth and shining, 1.5 mm. long excluding the tubercle, 



tubercle smooth, about A as long as the achene-body. — Differs from B. gracilenta in 



the broader leaf -blades and the numerous spikelets in the clusters. 



In bogs and on damp hillsides, Pennsylvania and western North Carolina. Summer 

 and fall. 



Page 206, under Carex folliculata, omit reference to Carex folliculata australis 

 and insert: 



2a. Carex Smalli^na Mackenzie. Yellowish. Stems and scapes erect, 4-8 dm. 

 high: leaf -blades 4-12 mm. wide: pistillate spikes 1-3, staminate at apex, widely 

 separate, erect, the lower long-peduncled, the upper short-peduncled : bracts long- 

 sheathing, exceeding inflorescence: stigmas 3: perigynia narrowly lanceolate, 2.5 mm. 

 wide at base, scarcely inflated, very green, finely many-nerved, 10-14 mm. long, gradu- 

 ally tapering into the bidentate beak, about twice the length of the ovate, acute to 

 cuspidate scale. — Differs from C. folliculata in the narrowly lanceolate perigynia, in 

 the shorter less pointed pistillate scales and in the pistillate spikes being staminate 

 at apex. 



In swamps and wet woods, South Carolina to Florida and Texas. Spring and summer. 



Page 209, omit Carex Joorii, Bailey and on p. 210 for Carex macrokolea read 

 Carex Joorii Bailey. 



Page 210 for Carex verrucosa Muhl. read Carex glaucescens Ell. 



Page 211, add: 



36a. Carex verrucosa Muhl. Stems and scapes 6-12 dm. tall : leaves glaucous ; 

 blades conspicuously striate, smooth below, 2-6 mm. wide, long attenuate and rough 

 above: staminate spikes 1-3, often partly pistillate: scales abruptly awned; pistillate 

 spikes 3-6, cylindric, 2.5-8 cm. long, erect on stiff peduncles: perigynia 3-angled, 

 glaucous, ascending, nerved, abruptly short-beaked, 3-4 mm. long, about equalling the 

 abruptly awned purplish-brown tinged scales. [Carex macrol'olea Steud.]— C glau- 

 cescens differs in having nodding pistillate spikes, reddish-brown tinged scales and 

 scarcely nerved perigynia, and C. Joorii differs from both in its staminate scales not 

 being abruptly awned and in having squarrose scarcely glaucous perigynia. 



In pine-land swamps. South Carolina to Florida and Mississippi. Early spring to 

 late summer. 



Page 211, after Carex Caroliniana, insert: 



40a. Carex Bilshil Mackenzie. Stems and scapes 3-6 dm. tall: leaf -blades 

 1.5-3 mm. wide, short pubescent (especially below) as are the sheaths: spikes 2-3,
