2. Glyceria stricta (Nob. in Fl. N. Zeal. i. 304); glaberrima, culmis cespitosis strictis foliosis, 
foliis brevibus strictis involutis, panicula stricta erecta contracta, ramis pedicellisque brevibus strictis, 
glumis insequalibus acutis superiore 3-nervi, flosculis 6-14 confertis, palea inferiore glaberrima acuta 
coriacea, nervis inconspicuis, squamula oblonga.—Poa Syrtica, Muell. MSS. (Gunn, 1463.) (TaB. 
CLXII. B.) 
Has. Marsh at Launceston, Gunn.—(Fl. Nov.) 
DisrRiB. Victoria, New Zealand. 
A very different-looking species from G. fluitans, of a pale-yellow colour.—Culms 14-2 feet high, strict, stout, 
leafy throughout, perfectly glabrous everywhere. Sheaths of leaves long, striate, rather swollen; ligula short, broad, 
membranous. Lamina short, 2-4 inches, subulate, strict, erect, involute. Panicle 4-6 inches long, very slender, 
strict, with short, stout, erect, appressed branches. Spikelets terete, rather crowded, pale-yellow, almost shining, 4 
inch long. Flowers six or seven to fourteen, closely imbricated. Glumes unequal, sharp; upper three-nerved. 
Palee quite glabrous, coriaceous; lower sharp, with obscure nerves. Sguamula ovate.— Tasmanian specimens are 
much larger than the New Zealand ones, but not otherwise different.—PrATE CLXII. B. Fig. 1, spikelet; 2, flower; 
3, squamule, pistil, and stamens; 4, caryopsis :—all magnified. 
Gen. XXII. POA, LZ. 
Spieule 2-8-fore; floribus distichis, hermaphroditis, nune basi lanatis, interdum abortu dioicis: 
Glume 2, mutice, subzquales. Palee 2, mutice; inferior obtusiuscula carinata v. concava ; superior bica- 
rinata. Squamule 9. Stamina 2-8. Caryopsis libera, v. paleæ superiori adherens.—Gramina plerumque 
extratropica; foliis planis, rarius setaceis ; spiculis majusculis, pedicellatis, paniculatis, rarius racemosis v. 
sessilibus et spicatis. 2 
A very large genus, found in all parts of the world, but most frequent beyond the tropics and in cold climates, 
where they often form extensive pastures.—Zeaves generally soft and flat, sometimes setaceous. Spikelets two- or 
many-flowered ; flowers sometimes unisexual, glabrous, or webbed with wool at the base. Glumes awnless, nearly 
equal. Lower palea blunt, awnless. Stamens one to three. Seed free or adhering to the upper palea.—The spe- 
cies of this genus are extremely variable, especially those of Australia and New Zealand, which often assume widely 
different forms. (Name, the Greek one.)
