42 ON SALIX TREVIRANI. 



be fonncl in other places, and thus be estabhshed as an mterestmg 

 addition to the British flora. 



The description which I have added is taken from a single 

 specimen of leaves and one of the catkins, but as Dr. Fraser has 

 kindly sent me cuttings, I hope in time to make a further exami- 

 nation of the plant in a growing state, and to correct any mistakes 

 where necessary. Bark of catkin- and leaf-bearing shoots light 

 brown; catkin-bearing shoot rather angular. Buds pointed, 

 nearly quite smooth, unless it be at the tip. Male catkins shortly 

 pedunculate, cylindrical, in an allied form broader about the 

 middle, rather dense, blunt, from half to three-quarters of an inch 

 long, furnished at the base with two or three linear or lanceolate 

 narrow leaves reaching half the length of the catkin, pointed and 

 finely serrated though not always, more or less downy or silky. 

 Young leaves on the ament-bearing shoot similar in form to the 

 bracts, serrated and more or less downy, having the margin 

 slightly recurved. Catkins diandi'ous, scales yellowish brown, 

 tipped with whitish hah's, which do not reach beyond the anthers. 

 Adult leaves about three inches long, narrow lanceolate, on a 

 petiole much longer than the bud, acuminate, smooth with rather 

 depressed veins, paler below, -with, a rather stout midi'ib and many 

 branching more prominent veins ; the leaves are rather wavy at 

 the margin, obscurely serrated, much less so than the young 

 leaves, which have rather glandular serratures. 



Dr. Fraser's Willow is the same, I think, as one whichi received 

 some years ago fi-om Woburn Abbey imder the name (no doubt 

 owing to some misplacement of tallies) of S. fusca. I mention 

 this name because the Willow may be found in other gardens under 

 the same. I have always considered it to be the male of S. hippo- 

 phaefolia, Thuil., but had no idea of its being a native. I find 

 by my notes that the Woburn Willow is diandrous, but sometimes 

 triandrous, that the filaments are pubescent at the base, and the 

 nectary bifid. In S. Idppophaefolia the young leaves are somewhat 

 reflexed at the margin, indicating perha^DS some affinity with the 

 viminales ; and the same remark applies to the male of S. rubra, 

 Huds. A Willow received from the Eev. L. Darwall is near to 

 S. Treiirani. My friend called it S. amlrogyna, as the aments 

 contain both male and female flowers. The lower part of the 

 catkins of 8. androgyna is generally staminiferous. The stamens 

 are two, scales pale yellowish downy, not equal to the ovarium 

 which is either downy or smooth. Stigmas cloven and reflexed, 

 germen on a short stalk, style equal to or longer than the stigmas. 

 Nectary, I think, in the male single, in the female about equal to 

 the pedicel of the ovarium. Sometimes the filaments are tipped 

 with a club-shaped ovariform body instead of anthers. The upper 

 part of the narrow cylindiical ament generally consists of female 

 flowers. Floral leaves serrated, downy below. Mr. Darwall 

 thought his Willow related to .S'. hippophaefolia. Through the kind- 

 ness of Mr. Charles Bailey, of Manchester, I have had an oppor- 

 tunity of examining Wimmer's published specimens, and among 

 my notes upon them I find the following : —
