 has omitted fonie of the preceding awidefs fpecies, and added 

 the following, viz. A. vcrt'icUlata, with Jlraight panicle, 

 interrupted by radiated rigid verticilli or whorls. A. Jlr'ida, 

 with ilifl' panicle, having flowers, and an ereft culm. A. 

 linearis, v.-ith fnbquatern digitated fpikes, and adprefled al- 

 ternate, imilateral flofcules. A., procera, with the foot-llalks 

 of the panicle, racemofe and foniewhat eretl, and the flowers 

 hairy and lanceolate. A. coromandcliana, with the panicle 

 ovate, patent, the foot-ftalks fimple ; fecond flowers, and

 A. avaiaceii,, with an erecl, very (lender panicle ; and the 

 awns twice longer than the calyx. A. ^lotucm/a., with bi- 

 fid, glomerate, terminal fpikes, and clawed plumofe braAea;. 

 A. Iiiteralis, with bilid, lateral, lolitary fpikes, and clawed 

 plumofe braftex. Dr. Stokes has obferved that this is an 

 artificial genus, and that the fpecies which are chiefly dillln- 

 guiOied by the prefence or abfence of the awn in the corolla, 

 and which is inconftant, are not precifely afcertaintd. He

ftale In wliicli the valves of the calyx arc found, immediately 

 after thefheddingof thepollcn andtheripening of ihefecd.and 

 like« ife to the flowers, whether they are fcattertd or ciuilei-ed. 

 The tnll fpecle;, which is annual, is common in fandy 

 rorn-fi( Ids, and flowers in June and July. It is liable to bo 

 fmutted. Ilorfes and goats cat it ; but flieep rcfufc it. 

 The lecond is, according to Haller, a variety of the former: 

 it is annual, and a native of I'Vance, Italy, Svviizcrlai.d, 

 Carniola, and Germany. The third is a native of Mont- 

 pclicr, Spain, and Siberia, was introduced by M. Thouin, 

 in 1778, and refcmblcs the firfl. The fourth is perennial^ 

 and grows wild about Montpelier. Th.e fifth is a native ot 

 Portugal. The fixth is a native of many paits of Europe, 

 and is perennial. Haller and Scopoli rank it amongft th.f 

 arundines. I'he Kalmuc Tartars weave mats of it, and 

 thatch their houfes with it. Goats will almoil die of hunger 

 rather than eat it. The fcventh refcmblcs the former: i» 

 perennial ; and a native of Germany and Switzerland and 

 about Verona; thefe two fpecies are referred by Gmeliii 

 to the genus calamostris, and are the C. arundo and C. 

 annidiiijcea. The eighth fpecies was obftrved by Scguier, 

 near Verona. The ninth is common in Sweden, and is 

 found in Scotland, in low pallures. The tenth and eleventU 

 viere found in the Ifland of Tenerift'e, by Maffon. The 

 twelfth is found in the fandy lands of Malabar. There arc 

 two varieties of the thirteenth, the rough and the fn'.ooth, 

 which Dr. Stokes in Withering's arrangement, makes a 

 dilUnft fpecies under the name ot A. idpinu, and fo clafleJ 

 by Gmelin: this is found plentiful in the higher downs ia 

 Dorfetfliii-e and the higher parts in the new foreft of Hants, 

 and flowers in May and June. But Dr. Smith (Flor. 

 Brit. vol. i. p. '8.) refers the A. cnn'ma, (a) of Hudfon 

 to the fpecies of A. can'ina, and alfo the A. "vinealis of 

 Witliering ; and fays it is perennial, flowering in July, and 

 found in meadows and moift pallures: and the A. can'ina 

 ((3 and ay) of Hudfon, and A. alpinn of Withering, above 

 deierlbed, to a diftinft fpecies, vi«. A. felacea, briftly B. 

 with lanceolate calyces and corolla awned at the bafe ; the 

 awn genicvdated and the radical leaves fetaceous. It is pe- 

 rennial, flowering in July and Auguft, and found on dry 

 heaths, frequently in the weft of England, and on the fen- 

 coaft near \Veymouth. The foui tcenth is perennial, a native 

 of moll parts of Europe, and found in moill meadows and 

 paftures, and alio in ftiif cold arable lands, where it is very 

 troubleiome ; for when fueh lands are brokcMi up and fallow- 

 ed, the roots are feparated with difficulty horn the adhefivc 

 foil. It flowers in July and Angult. Hudfon joins this 

 fpecies with the capillaris, pumila, alba, and lylvatica, under 

 the name of polymorpha; and Gmelin queries whether thele 

 and alfo the virginica are not varieties <-,f the fame fpecies, 

 owing their diffevenec merely to the foil; fome have fuppt)fed 

 that this is the famous orchestoh grass. The fifteenth 

 is very common, but chiefly grows on poor, dry and landy 

 land, and is dilliked by cattle, as are the bents in general ; 

 it flowers in May and July. Gmelin queries whether it 

 be not a fpecies of alopecurns. Some have fuppofed 

 that the A. dipilhir'is of I>inna^us, is the fame with the A, 

 •viih^aris, which has a fpreading panicle, branches bare at the 

 bafe ; florets numerous, calyx inner valve fmooth, outer 

 fernilated upwards ; blolfom inner valve, but half tlie fizc 

 of the outer ; deciduous. I^innjcus confounded thele two 

 plr.nts ; but the error was difeovercd by Dr. Smith, In 

 general habit, fays Withering, the plants are very much 

 alike ; but the real A. cnpulatis has the fl;cm, leaves and 

 hufl<s of the calyx quite fmooth, as well as cveiy other 

 part of the plant, whilll in the A. vulgaris the ftem-leave« 

 ajc rough, and the hullii of the calyx arc fernilated on the 

 3 K keel.
