THE SALIX LISTS IN THE 'LONDON CATALOGUE.' 467 supposed aurita x phylicifolia ought to be tested in cultivation by careful observation at different stages of growth. The winter con- dition, e.g., affords an excellent opportunity for judging supposed hybrids with the Caprea by the appearance of the flowering buds. 1403 phylicifolia X Caprea. As in the case of the last, there is much S. phylicifolia growing by river- sides, and especially in straths, which suggests a cross with Caprea, by the woolly hair of the young foliage ; a symptom which usually disappears in cultivation. After examining many specimens of S. laurina Sm. and some living plants, I am unable to agree with Andersson and others that Smith's plant is S. Caprea x pliylicifolia. The plant that has been cultivated at Kew as S. laurina Sm., Leefe's ii. 38 of the earlier set (" S. laurina Sm. received from Borrer as the plant of Smith "), and Leefe's Salict. Exs. Fasc. i. 3 (*S laurina Sm."), all seem to be the same hybrid, and to have no evidence of S. Caprea which would not equally bear witness to S. cinerea ; and in the foliage to have leaves which bear much resemblance to cinerea leaves and none to Caprea. Mr. Charles Bailey has in his herbarium three sheets of "/S. laurina which seem to be really S. Caprea x phylicifolia, viz. (1) Wirtg. Herh. PI. Sel. Fl. Rhen. vi. 260 ; (2) Rchb. EL Germ. 1020, W. Hofmeister); and (3) Wimmer 90 (ex hort. Berol.) ; but none of these is British, and they do not represent Smith's plant as handed down to us by Borrer, Leefe, and the Kew Gardens. With these three exceptions, all the laurina Sm. I have noted belongs to S. cinerea x phylicifolia^ and S. laurina Sm. is the synonym of this hybrid ; while S. Caprea x phylicifolia is uncertain as a British plant. 1403 phylicifolia X cinerea x Caprea {tephrocarpa F. B. White). Of this I have seen no specimens. 1403 phylicifolia X Lappofium [Lapponum pthylicifolia Linton). It is a pity that this hybrid is inserted here, inverting the order of the two parent species for no reason whatever (Journ. Bui. 1891, 214). 1403 phylicifolia X Myrsinites (Normanni Ands.). This has been entered in my list for one vice-county, viz. Mid-Perth, on the strength of specimens from a bush discovered by the Rev. E. S. Marshall, and so named by him and Dr. F. B. White, It jnay be so ; but the evidence of S. Myrsinites is not very clear, compared with intermediate plants (accidental garden products) I have in the garden of this hybrid, which exhibit both parents about equally well. Unfortunately this bush has not been cultivated. 1403 phylicifolia X repens [Schraderiana Willd.). Entered in both lists, but I have seen no specimens which are fairly entitled to be so named ; in two cases cultivation (in the garden at Bourne- mouth) proved years ago that suspected plants have no repens in them at all. 1403 b. and c. See remarks on these in the early part of this paper (p. 462). 1403 phylicifolia c. nigricans X Arhuscula {Kraettliana Briigg). It is perhaps by an oversight, due to Dr. White not having seen his list in type, that S. Arhuscula x nigricans is placed here, and the corresponding hybrid S. Arhuscula x phylicifolia under S, Arhuscula.
