48 TRIANDKIA. DIGTNIA. 



rvfa. El. This genus appears to be very closely allied to 

 Piviicum, and somewhat to Milhim, particularly to the 

 M. awphicarpon of Parsh. The JMilium viUosum of Ja- 

 maica may probably belong to this genus. 



73. PHALARIS. Z. (Canary-Grass.) 



Calix 1 -flowered, 2-vaIved; valves subovate 

 or lanceolate, carinate, equal and nerved, in- 

 cluding the corolla. Corolla 2-valved, mostly 

 hairy at the base. 



Flowers generally in terminal cylindric or ovate spikes. 

 In P. canariensis, the corolla consists of 4 valves, in P. 

 aquatica of 3. 



Species. 1. P. maritima {Aninda arenaria. Lin.) This 

 species may be considered as intermediate between Arim- 

 da and Phalaris. — On the coast of New- Jersey. Z. Col- 

 U71S, Esq. In Europe considered of great importance for 

 arresting and consolidatmg the movable sands of the sea- 

 coast. The rest of this genus is chiefly confined to the 

 south of Europe and Northern Africa (Barbary.) 



74. BRUCHMANNIA. Jacquin, Phalaris eru- 

 cmformis. L» 



Calix 2-valved, 1-2-flowered, valves semiob- 

 cordate, inflated, equal. Corolla 2-valved, includ- 

 ed within the calix, valves unequal, the dorsal 

 valve setaceously acuminatej one of the flowers 

 often abortive or wanting. 



Culm erect, panicle irregularly spiked, spikelets inter- 

 rupted and subdivided; flowers disposed in 2 rows on 

 onesideof therachis. (Valves of the cahx somewhat mar- 

 gined or slightly carinate, gibbous, and abruptly acute, 

 with scanose margins, in the American plant generally 

 l-flowered, corolla glumes unequal, the dorsal valve con- 

 vex, terminated by a short setaceous mucrone; smaller 

 Talve flat, rather acute; stigmata long, filiform and hir- 

 sute.) 



Species. 1. JB. enicaformis. Around Fort Mandan, on 

 the Missouri, in alluvial soil. Flowers in July. There 

 is only as yet one species of this curious genus discover- 

 ed, there being no apparent distinction observable betwixt 

 the American plant and the one figured and described 

 by Jacquin in his Hortus Schoenbrmmensis, It is equally
