Poa alpina, 



Alpine and Arctic Europe, Asia and North- America. Deserves to 

 be transferred to other higher mountains as a nutritious perennial 

 pasture-grass. P. Sudetica (Haenke) and P. hybrida (Gaudin) are 

 mentioned also as excellent alpine grasses. 



Poa aquatica, Linn. (Glyceria aquatica, Smith.) 



Europe, Northern and Middle Asia, North- America. This con- 

 spicuous water-grass attains a height of about 6 feet. It is perennial, 

 and deserves naturalisation in our swamps. It produces a large bulk 

 of foliage, and may be disseminated for fodder-purposes. On the 

 testimony of Dr. Curl, this is one of the best feeding grasses in New 

 Zealand. 



Poa arachnifera, Torrey.* 



The Blue Grass of Texas. Prairies of Louisiana and Texas. 

 Perennial, with creeping roots. It spreads rapidly, surpasses in size 

 the Kentucky Blue Grass (Poa pratensis), and is known to have 

 grown 10 inches in ten days. Stock of all kinds have a predilection 

 for it. The winters of Texas do not even nip it, but it dies down 

 during summer ; it is never quite tramped out [G. Hogan]. It bears 

 heavy pasturing, and can also be utilised for lawns and as a forest- 

 grass [S. Tally]. For permanent pasture, this promises to be one of 

 the very best grasses yet brought to the attention of the Southern 

 States [Dr. Vasey]. 



Poa Bergii, Hieronymus. 



La Plata-States. Supplies excellent fodder there, with some 

 species of the section Eragrostis. 



Poa Billardieri, Steudel. 



Extra- tropical Australia. A perennial rigid grass, of some value 

 for saline meadows. 



Poa bulbosa, Linn 



Europe, North-Africa, extra-tropic Asia. A perennial species. 

 Dr. J. Aitchison singles it out for laudation as a profuse pasture- 

 and hay-grass in Afghanistan. Closely allied to it is P. alpina, L. 



Poa csespitosa, G. Forster. 



Extra-tropical Australia and New Zealand, ascending alpine 

 elevations. A tufty extremely variable grass, available throughout 

 the year for pasture-feed, when young or when offering flowering or 

 seeding-stalks, or when presenting tender varieties ; the rougher
