ON SOME SCOTTISH WILLOWS GATHERED IN 1892 31 



which may be S. Lapponum x Myrsinites, but from the poor 

 material obtainable there can be no certainty. 



\S. Lapponum x nigricans.- At about 2700 feet in Caenlochan 

 Glen, 90; on the "gentian rocks." A small bush, about two 

 feet high, growing with the parents ; unfortunately, the material 

 was scanty, and my cuttings do not seem likely to grow. When 

 alive, it rather suggested aurita x Lapponum ; aurita does not, 

 however, occur at the spot, and nigricans came out clearly as 

 the specimens dried. Dr. White agrees with me in placing 

 them here. I have examined Laestadius's specimens of his 

 Lappono-nigricans from Karesuando, at South Kensington ; two 

 of them are evidently, as Anderssen has noted, glauca x nigricans, 

 but the third is clearly correct, and closely resembles the 

 Forfarshire form. 



f S. Lapponum x repens. By the Lochsie, at about 1500 feet. 

 Very dwarf, creeping and rooting. Both parents have left 

 unmistakable traces of their influence ; but no flowers or 

 fruit were to be had. The leaves, however, afford sufficient 

 material for a confident determination. I have healthy-looking 

 plants in cultivation. 



6". Myrsinites x nigricans (S. Wahlenbergii, And.) I found this in 

 Caenlochan, as well as (in various forms) in Glen Callater and 

 Corrie Kandor several bushes being male. I also have the 

 male plant in cultivation from Glen Doll or Glen Fiagh. 



*S. nigricans x repens. A barren bush, growing in company with 

 these species, a few hundred yards from the Spittal of Glen 

 Shee, 89 ; quite intermediate in leaf-characters. 



^S. phylicifolia x repens (S. Schraderiana, Willd.) By the Lochsie, 

 at about 1400 feet, in two forms one (probably male) low- 

 growing, with shorter, ovate, less silky leaves ; the other 

 (female) taller, the leaves lanceolate, strongly resembling phyli- 

 cifolia in their upper surface, and very silky beneath. Like 

 phylicifolia in the catkins, which, however, are somewhat 

 smaller, and have the capsules more crowded. Dr. White 

 says ("Revision," p. 395): "It is possible that a hybrid 

 between S. repens and S. phylicifolia ( = S. Schraderiana, Willd., 

 which is known only as a cultivated plant) also occurs in 

 Britain ; but more specimens must be seen before it can be 

 recorded."
