THE WILLOWS OF OHIO. 279 
The ripe capsules of Salix amygdaloides are narrowly long-conic 
on long pedicels, contrasting with the short pedicelled capsules 
of Salix nigra and giving the aments a very different appearance. 
S. amygdalotdes is characteristically a swamp plant though 
it is not absent from river banks. In Ohio its range is over the 
northern and western parts of the state. Columbus is near its 
southern limit in central Ohio; further east it does not extend 
so far south while further west I suspect it may even reach the 
river. It is a north-western species of which Ohio is near the 
eastern limit. 
While remaining for the most part recognizable in the west, 
Salix amygdalotdes loses the glaucescence of the under surface 
of the leaf while the upper surface brightens till it is almost like 
Salix lucida. The shape of the leaves also changes and becomes 
shorter and broader. Southwestward it grades into the varieties 
of S. nigra which occupy the region. About St. Louis there is 
a great complex of the amygdalenae in which pure forms of the 
three constituent species are uncommon and there are all sorts 
of interconnecting variations. In Ohio we have only two species 
together and intermediates are rare though several have been 
collected. 
LUCIDAE. 
Trees or shrubs, branches shining; leaves often very long 
acuminate, broadly lanceolate to ovate, thick, glossy, strongly 
glandular; catkins leafy peduncled, thick and dense, scales cadu- 
cous, often dentate, filaments pubescent, capsules glabrous, style 
short, stigmas thick. 
SALIX LUCIDA Muhl. SuHIninc WILLOW. 
A bush or very rarely a tree 8 m. tall; bark smooth or near- 
ly so; twigs shining orange brown, glabrous; buds rather narrow- 
ly ovate, large, (5-10 mm. long) bright reddish brown in spring, 
duller earlier in the season. Leaves reaching an extreme length 
of 18 cm. and a breadth of 8 cm., varying from ovate to lanceolate, 
rounded or narrowed at the base, prcminently glandular-serrate, 
especially on the deciduous stipules, often covered when young 
with long tawny scattered hairs, becoming glabrous, coriaceous, 
very glossy above so as to give the plant a very beautiful appear- 
ance different from any other willow. The thickness of the leaf 
makes the rather regular veining difficult to make out. Stami- 
Plate Il. Salix amygdaloides. 
All parts typical, natural size except the capsule which is enlarged 
three times.
