East and West Greenland, Pribilof Islands, St. Lawrence Island, 
Arctic Siberia, Novaja Semlja, Spitzbergen, Finmark. 
19. Poa glauca Vahl. var. tenuior Simmons, Le, p. 162. 
Dense caespitosa; culmi circa 20 cm alti, graciles, erecti, infra medium 
foliosa; folia plana, eulmum latitudine duplo plusve superantia, ligula 
elongata, acutiuscula, vulgo integra. Panicula angusta, contracta, vel 
ramis infimis patulis, solitariis vel duobus; capillaceis vel parum robustiori- 
bus. Spiculae 1 — pauciflorae, anguste lanceolatae, violascentes, quam 
in forma vulgari multo minores. 
I was, for a time, inclined to identify this form with P. attenuata 
Trinius, in Bunge, Verz. Altai Pfl, p. 9, but that plant should have the 
leaves „perangusta, subeonvoluta*, which does not agree with my plant, 
which must at present be regarded as a variety of P. glauca.

13. Poa evagans Simmons, l. c., p. 165. 
Laxe caespitosa — stolonifera, 8—12 cm alta, glabra. Rhizoma 
tenue, ramis suberectis, vaginis persistentibus vestitum. Folia angusta, 
involuta. Ligula protracta, acuminata, in foliorum culmi brevior, trun- 
cata vel paulo lacerata. Folia culmi 2—3, vagina longa inflata, lamina 
brevi, in superiore brevissima.  Culmus strictus, infra medium foliatus. 
Panicula 2—3 cm longa, densissime contracta, ovato-cylindracea, ramis 
brevibus, capillaribus, 1—3 spiculas gerentibus. 
3-florae. Glumae aequilongae ad basin purpurascentes, ceterum mem- 
branaceo-flavescentes, obsolete  carinatae, trinerviae, apicem versus 
erosae. Paleae obtusae, glumis simillimae; inferior 5-nervia, ad basin 
pilis paucis, brevibus instructa, superior 3-nervia. — Fig. Tab. nostra 8, 
fig. 2—1. 
In habit this grass differs rather much from the common type of a 
Poa, but there is a certain resemblance to P. abbreviata, and also to 
P. glauca var. arenaria, in the company of which it grew. I think 
it is most nearly allied to P. abbreviata and the specific name has 
reference to the difference from that species in the built of the shoot- 
System.
