1907] Knight,— Three Plants from Maine 203 
Shrub about 1 meter tall; foliage very variable, glabrous above, 
pubescent beneath even when mature; the leaves either simple, oblong- 
ovate and dentate or entire, er variously lobed, or compound and 
composed of five to seven oblong-ovate leaflets with margins dentate or 
entire; peduncles and pedicels pubescent; cymes decompound, fifteen- 
to thirty-flowered, the flowers not appreciably different from those of 
Pyrus Americana (Marsh.) DC.; fruiting pedicels and young twigs 
pubescent; mature twigs glabrous, similar in color to those of Pyrus 
Americana; fruit only sparingly maturing, a majority of the blossoms 
not being fertilized, red, 6 mm. in diameter, not distinguishable extern- 
ally from that of Pyrus Americana; the seeds very abortive, showing no 
embryos in the case of several examined. Fruit ripe and falling August 
12, 1906. Type locality: growing associated with supposed parents, 
Bicycle Path, Bangor; flowering specimens June 9, 1905; fruit August 
12, 1906. Type specimen No. 5224 O. W. K. 
Along the shores of the Penobscot at Bangor, growing near the type 
of Salix coactilis Fernald, is a shrub, which at certain stages of growth 
I have been inclined to refer to S. coactilis although later in the season 
it more nearly resembles S. cordata Muhl. After study of this peculiar 
shrub for several seasons its true affinities seem well established and 
I propose to call it:— 
Salix coactilis X cordata, hyb. nov. 
Characters:— Shrub about 2 meters tall; branchlets reddish green 
to blackish and somewhat quadrangular; youngest branchlets gray 
and pubescent to puberulent; leaves oblong to lance-ovate, long- 
acuminate, petioled, at first reddish green to red beneath and pubes- 
cent, especially on mid-rib and veins, above deeper red, pubescent on 
the mid-rib at least, becoming green with age but always paler below 
and remaining pubescent on mid-ribs above and below, in maturity 6 
to 12 em. long, 2 to 4 em. broad, rather finely and somewhat irregu- 
larly glandular-dentate; petioles pubescent even in maturity; stipules 
semi-ovate, glandular-toothed, persistent on the younger branchlets, 
4 to 10 mm. long; aments on short leafy peduncles, expanding with 
the leaves, in anthesis 1 to 2.5 cm. long, in fruit 2 to 4 cm. long, 7 mm.
