igo2] Holm On the Genus Arctophila, Rupr. 8t 



Poa {Arctophila) remotiflora. 



Culmus ^-i pedalis, minus crassus ac in praecedentibus, nodo 

 uno alterove exserto ; folia praeced. angustiora, ad summum 

 lineam lata, flaccidiora, complicata ; panicula apice erecta, radii 

 infimi semiverticillati. divaricati et unus saepe deflexus ; longiores 

 ultra medium nudi ; spiculae 3-3)^ lin. longee, 3-4 florae: flosculi 

 satis remoti, erecti, acutiores quam in reliquis specc. hujus sec- 

 tionis, pedicellis partialibus (jam flosculi secundi ) visilibus. 

 Poa {Arctophila) similis. 



Valde similis quoad habitum P. arctic?e. R. Br. et commutatu 

 facilis, dilTert vero ; spiculis subbifloris, e fulvo et purpurascenti 

 variegatis ; flosculo secundo longius pedicellato, basi setulis (nee 

 lana) obvallato, dorso et lateribus g'labro, ecostato, glumisque 

 angustioribus, longioribus. A. P. ?-'W6///?ora (quacum promiscue? 

 crescit) diversa : statura minori : 3-5 pollicari, nodis omnibus 

 obtectis ; radiis infimis geminis vel ternis ; spiculis minoribus, vix 

 bilinealibus et c Vix var. hujus esse crederem. 

 Poa {Dtipontia ? ) scleroclada. 



Transitus quasi inter Arctophilas et Dupontias ; habitus 

 plane idem ac P. lati/lorse., re?noti/lof?e et rel. ; folia eadem, nodus 

 unus alterve exsertus. Spiculae sequentis, sed gluma quslibet 

 flosculo suo distin te brevior. Culmus 12-15 pollicaris, radii 

 infimi paniculce semiverticillati, patuli, unus interdum deflexus ut 

 in P, remotiflora, cujus habitu gaudet, sed tota panicula multo 

 rigidior est, spiculae crassiores, majores, color fulvus magis 

 praedominans ; spiculae interdum 4-florae cum rudimento. 



The genus seems to be rare in North America, but has been 

 collected in various parts of Alaska and on the adjacent islands, 

 besides in the British provinces, mostly south of the arctic circle. 

 These specimens have been generally identified as A. fulva or A. 

 pendulina, but as stated above, the former is not with certainty 

 known except from Muckelung River and the Hudson Bay region, 

 while we have seen no specimens of the latter from this continent. 

 A very peculiar plant was collected on the arctic coast near Point 

 Barrow by Dr. Murdoch (1883) and having been submitted to Pro- 

 fessor Hackel for identification, it was at once distinguished from 

 all the others and described as A. mucronata Hack. As indicated 

 by the specific name the midrib of the flowering glume is produced
