36 TRIAND. DIGYN. 



Hab. Common in woods and thickets. — (3. Scotch Alps, plentiftil. 

 FI. June, July. 11 ■ 



One to three feet high, slender and delicate in all its parts. Leaves 

 narrow, linear, acute. Panicle with the branches at most erecto- 

 patent. Spikdefs not crowded. Cal. valves unequal, ovato-lanceo- 

 late, acute, rather obscurely ril)bed. Ext. valve of cor. lanceolate, 

 very obscurely ribbed, pubescent on the keel and hairy at tlie base, 

 but very slightly webbed. Inner vah-es, as, I believe, in all the ge- 

 nus, bitid at the point. — There can, I think, be little doubt of the 

 P.' s^hnica being merelv an alpine var. of thisj — glaucous, smaller, 

 with the spikelets rather larger in proportion. Such seems to be 

 the opinion of Schrader ; and ^^'uhlcnberg and Gaudin have united 

 the P. ccesla of E.B. with the P. glauca; the latter considering botli 

 as varieties of P. nemoralis. Wahlenberg, indeed, though he makes 

 a species of P. glauca, says that it is as it were intermediate be- 

 tween P. frivialis and nemoralis ; " sed colore glauco eximio ab 

 utraque diftert." The P. pulchcllu of D. Don's MSS. I am sorry I 

 cannot distinguisli irom the glaucous var. here noticed; except that 

 it is somewhat less glaucous, or, as Mr. Don expresses it, " glauco- 

 I'iresceHs."— In all I find at the base of the florets' a more or less 

 apparent filamentous, webbed substance. 



15. P. decumbens {decumlent Meadow -grass), panicle nearly 

 simple contracted few-flowered, calyx as long as the 4-flowered 

 spikelet, ligule a tuft of hairs. Light/, p. 102 [Fcstuca dec).

 hills, Mr. Greville. Ft. July. 1^ . 



One foot long, procumbent, flowering culm only erect. Leaves linear, 

 rigid, acuminate, hairy as well as the sheaths. Cal. valves nearly 

 equal, lanceolate, acute, nerved, -with broad thin margins, scabrous 

 on the keel. Ext. valve of the cor. ovate, nerved or ribbed, having 

 a small tuft of hairs on each side the base ; apex with three teeth : 

 7?)^ valve obtuse, entire at the point, ciliated at the angles of the 

 fold. — Habit very different from Poa ; and Mr. Brown suggests that 

 it may belong to his genus Triodia. It is DantJionia of Decandolle ^. 



'^ Besides the foregoing species of Poa, the two following are to be added 

 as natives of Scotland: but as I have never seen specimens, so as to be able 

 to verify them, or to put them in their proper place in the genus, I think it 

 better to give them in a note. 



1. P. slricta, panicle branched, spikelets of 3 flowers ovate, cal. glumes 

 lanceolate o-nerved nearly equal mucronated keeled, florets 5-nerved 

 truncated at the apex villous at the base. D. Don, Descr. of New or Rare 

 Plants of Scott, p. 4. 



H.-iB. Pastures in Angus-shire, G. D,o!t.— Said to be very near P. pra- 

 tensis. 



2. P. leptostarhya, panicle contracted somewhat racemed, pedicels very short 

 glabrous, spikelets 2-flowcred, cat. glumes kinceolate mucronate equal
