468 THE SALIX LISTS IN THE 'LONDON CATALOGUE.' 



Obviously it is most convenient that both should stand together 

 S. Arbuscula. 



1403 phijUci folia c. nigricans x Myrsinites {Waldenbergii Ands.). 

 It has before been pointed out that 8. IVahlmben/ii is the latest of 

 four or more names for this hybrid. If S. punctata Wahl. is un- 

 satisfactory through some confusion of original specimens, which 

 is the objection advanced, then S. Myrainites-nigricans Wimmer 

 should be adopted (18GG). Andersson used S. myrsinitoides Fr. in 

 DC. Prodr. xvi. (2), 290, in 1868, and replaced this by S. Wahlen- 

 bcyyii in Blytt's Norges Flora a few years later (1874). 



1403 pliyUcifoUa c. nigricans X rcpens (^irigricans-repens Heiden- 

 reich). Dr. White's description of specimens from Mid-Perth looks 

 as if the right plant had been found ; but I have seen no satisfactory 

 British specimens, and have entirely failed in my attempts to pro- 

 duce artificially both this hybrid and also S. phylicifolia x repens. 



1404 Arbuscula x Myrsinites [serta F. B. White). Of this also 

 I have seen no specimens, suspected plants having turned out 

 otherwise in the garden. These two species do not cross readily. 



1404 Arbuscula x phylicifolia [Dicksoniana Sm.). Dr. F. B. 

 White considered that Leefe's published specimens (Sal. Ka-s. i. 12) 

 ■'received from Mr. Borrer as from Smith" were rightly referred 

 by Leefe to S. Dicksoniana Forbes, t. 55, fig. 1. But he mentions 

 Forbes having doubts whether his plant was the same as Smith's, 

 and quotes Leefe as saying that the plant described by Smith "must 

 be regarded as at present unknown." The description of Smith's 

 plant (Sm. Eng. Fl. iv. 196) does not fit Leefe's cultivated plant in 

 important particulars. In Smith's plant the ovary is " on a longish 

 smooth stalk, elevated somewhat above the scales"; the catkins are 

 ovate, " in which the present Saiix differs from all we have hitherto 

 described, and agrees with a few other dwarf species, particularly 

 the rosmarinifnlia and Arbuscula" [S. Arbuscula Sm. = S. repens h.). 

 And again, under !S. ^'Arbuscula" (i.e. 8. repens L.), he says of its 

 catkins that "by their short ovate figure they assist materially in 

 characterizing the species, agreeing most with those of 8. Dicksoniana, 

 from which the leaves of the present [species] widely difi'er in form 

 and silkiness." It is evident that the 8. Dicksoniana of botanic 

 gardens and of Leefe's 8al. Fxs. Fasc. i., with its cylindric catkins 

 and shortly-pedicelled ovaries, cannot be the same as the plant 

 Smith describes, and which he carefully notes differs from the 

 foregoing species (some Arbuscula and phylicifolia forms) by their 

 ovate catkins. Judging from Smith's description, one may say that 

 plant may very possibly have been ^S'. phylicifolia x repens, but 

 cannot have been 8. Arbuscula x phylicifolia. If the botanic garden 

 Dicksoniana, which Leefe pu.blislied in his set, be this hybrid, then 

 its synonym should be *S'. Dicksoniana Leefe, or possibly 8. Dick- 

 soniana Forbes, but not 8. Dicksoniana Sm, I have not yet got this 

 plant for cultivation. 



1405 viminalis x CaprecB (8. 8mithiana Willd.), with five 

 varieties of this compound hybrid, a. stipularis Sm., b. sericans 

 Tausch., c. veliitina Schrad., d.ferruginea G. Ands., e. acuminata 

 Sm. The unsatisfactoriness of Andersson's arrangement, or of
