THE WILLOWS OF OHIO. 279 



The ripe capsules of Salix aniygdaloides are narrowly long-conic 

 on long pedicels, contrasting with the short pedieelled capsules 

 of Salix nigra and giving the aments a very different appearance. 



5. aniygdaloides 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 aniygdaloides 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 5. 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. Shining 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 reddiih brown in springs 

 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, prominently 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 II. Salix aniygdaloides. 



All parts typical, natural size except the capsule which is enlarged 

 three times.
