jB. JAPOMCTs Thiinl). Naiigatuck (A. K. Hiewitt). Fugitive 

 from Eurasia. 



B. ixcANUS (Shear) Hitchc. Willimantic (G. E. Nichols), Col- 

 chester, Southbury and Oxford (Harger), Windsor (Weatherby), 

 Waterbury (A. E. Blewitt).

t B. margixatus Nees. Waste ground, Naugatuck (A. E. Blewitt).

LoLiuM MULTiFLORUM Lam. Bridgeport (Eames). 



t L. MULTIFLORUM Lam., var. dimixutum Mutel, Fl. France, iv. 130 

 (1837). L. Boiichcanum Kunth. Fields and roadsides: East Haven 

 (Bissell), Bridgeport (Eames), Greenwich (Bissell & Weatherby). 

 This has been confused with L. yereyinc. Forms intermediate between 

 this and the typical form occur at Fairfield and Bridgeport (Eames). 



The above forms are difficult to distinguish in herbarium material 

 by any clear characters, but are kept apart as sub-species or even as 

 species by practically all recent European authors on the ground that 

 one is annual and the other perennial. . The specimens cited under the 

 variet}', except that from Greenwich, were referred to L. percnnc in the 

 Catalogue. 



The following key may help to distinguish these plants: — 



A. Unexpanded leaves folded; rachis usually smooth except on the angles; 

 glumes of the upper spikelets exceeding the contiguous floret, usually 



more than half the length of the spikelet L. perenne 



A. Unexpanded leaves rolled in from each margin toward the mid- vein; 

 rachis usually roughened; glumes of the upper spikelets not exceeding 

 the contiguous spikelet. B. 

 B. Annual; spikelets 10-20-flo\vered; glumes of the lowest spikelets 



often exceeding the contiguous floret L. multiflorum 



B. Perennial; spikelets 5-8(9)-flowered; none of the glumes exceeding 

 the contiguous floret L. multiflorum, var. diminutum 



t L. TEMULEXTUM L., var. LEPTOCHAETOX A. Br. Associated with 

 the typical form, Bridgeport (Eames). 



t HoRDEUM TRIFURCATUM Jacq. Rare. Waste ground and fence- 

 rows: Berlin and Southington (Andrews). 



tH. Caput-Medusae (L.) Cosson. Formerly abundant along a 

 roadside at liridgeport, but the station has since been destroyed 

 (Eames). Fugitive from Europe. 



tH. MURIXUM L. Wall Barley. Way Bent. Waste ground:
