Herschell Isl. Flowers not yet opened (July 18th, 1906). It 
differs a little from the typical species in the glumes being unequal, the 
lower pale acute and to a small degree longer than the upper one. In 
one specimen the upper pales and the flowers proper were transformed 
into galls (through nematode worms). 
King Point. Specimens with panicles still enclosed in the sheaths; 
panicles, when removed from the sheaths, laxe; sterile shoots long-leaved, 
high; the form agrees with var. arundinacea (TRIN.) LEDEB. (July 4th, 1906). 
Some American authors have splitted A. /atifolia into several species 
and e.g. take A. arundinacea (TrIN.) BEAL as a separate species. In 
Britton’s and Ryppere’s list (Bull. New York Bot. Garden, 1901) Mr. 
Nasu describes three new species from the Yukon territory, some of which 
(A. macrophylla NasH?) may be what I have here retained under the old 
collective name.

King Point. Among other grasses collected near the river on 
July 4th, 1906, I found a tuft of a species which with some doubt I refer 
to Trisetum flavescens, although its panicle is so young that it is quite 
included in the sheath. KJELLMAN (1883) mentions the species from Port 
Clarence and states, that it differs in some respects from the type form 
1 A sterile shoot of a coarse Carex probably of the rigida-group, has been collected at 
King Point.
