Folia in caule inferiore majora et longiora sunt. Desunt margines 
divaricati ochreae omnino quando floret. 
Plantae sterilis terrestris folia ut in praecedente sed majore 
et dimidio longiora quam in P. mesochora. Internodi vero duplo 
longiora quam in planta typica. Adsunt margines campanulati 
erose-ciliati perparvi. Plantam aquaticam non inveni. Planta 
inter P. mesochoram et P. ammophilam intermedia. 
Terrestrial Phase. Differs from the type in having the leaves 
more or less strigose with scattered appressed fine hairs. The 
internodes are shorter and the ochrea appressed hirtellous, with 
rather long hairs, the spike is smaller less than 2.5 cm. The mid- 
vein is appressed hirtellous and only scabrous in the type. It 
agrees with the type in the shape of the leaves and their general 
aspect. The leaves of the variety are larger below on the stem. 
The spreading ochrea margins are absent as in the type at flower- 
ing time. 
Sterile Spring Plant. Weaves as in the fertile summer plant 
but larger and pubescence softer, leaves nearly one half again as 
long as in the corresponding phase of the type. The campanulate 
erose-ciliate borders of the ochreae are present but smaller and 
less conspicuous. Aquatic phase not seen. 
The type of the new variety is a single sheet of a specimen 
gathered at Millers, Ind., Sept. 21, 1911, No. 2090. The spring 
sterile phase is represented by Nos. 857a and 857b found at the 
same place, June, 1, 1911. The plants have that marked character- 
istic of P. mesochora, viz., absence of ochrea border at the time 
of blooming. They have almost the pubescence of P. ammophala, 
but the latter always has the borders present when in flower.

SPRING TERRESTRIAL PHASE. Plants rather variable in appear- 
ance ranging from very leafy glabrate specimens of moist habitat 
(internodes 2.5 cm.) to hirsute with nodes 5 cm. apart. Ochreae 
very hirsute with wide-spreading broad herbaceous ciliate types 
or borders often 2 cm. or more broad in sterile plants. This border 
is seldom wanting or withered in elongated specimens straggling 
over bushes and sedges, but often diminishing in size as the 
plant grows larger. Leaves oblong to ovate-lanceolate from 
glabrate with ciliate scabrous margins to strigulose and hirtellous, 
or hirsute, usually always with hirsute appressed ochreae, and
