A striking species of the Lapponicum series, which in its 
many-flowered compact truss of blue-purple flowers suggests 
Rh. intricatum, Franch. But it is far removed from that species, 
which is an exceptional one in the Lapponicum series, as I have 
explained above when writing of Rh. complexum, Balf. f. et 
W. W. Sm. Rh. hippophaeoides finds its nearest ally in 
Rh. Webstertanum, Rehder et Wilson. Like that plant it is 
hoary, but there is more yellow in the tint of its foliage and 
twigs. It is also a more virgate shrub than is Rehder and 
Wilson’s species, and has much larger flower trusses—7-flowered 
instead of 2~3-flowered. I may add also that the style of 
Rh. Websterianum is often lepidote or hairy. In indumentum 
our species belongs to a set of species—Rh. idoneum, Balf f. et 
W. W. Sm., Rh. polifolium, Franch., in addition to Rh. intricatum, 
Rh. thymifolium, Maxim., Rh. Websterianum—which have re- 
markable shiny grey not punctulate under-leaf surface, the scales 
being large and almost or quite ee Rh. hippophaeoides 
is now in cultivation.
