Xolisma mariana, X. lucida and X. 



oval i folia have been referred by IJentham and Hooker and other authors 

 to the genus Pieris, but they differ from that genus not only in the thickened 

 sutures of the capsule, but also in the awnless anthers; apparently these 

 authors did not consider the structure of the capsule and did not distinguish 

 between appendaged or awned anthers and the appendaged filaments of 



these species; they considered the appendages of the filaments as equal 



in taxonomic importance to the awns of the anthers, but the former consti- 

 tute a less constant character and the appendages may become more or 



less indistinct or obsolete and are entirely absent in some species of 



Xolisma as in X. villosa, while the awned anthers constitute a constant 

 and important character.

This variety is nearest to X. ligustrina foliosijlora C. Mohr, which in its 



typical form has nearly glabrous leaves lustrous above and usually a more 



leafy inflorescence with a nearly glabrous corolla {Andromeda paniculata 



var. 2, foliosiflora A. floribusrglabellis Miehaux, Fl. Am.-Bor. i. 255 [1803] ), 



while the variety has the leaves grayish above from a dense covering of 

 short appressed hairs, becoming glabrescent at maturity, loosely or 

 sparingly villose on the surface beneath and densely villose on the midrib 

 and on the prominent veins; the inflorescence is usually less leafy and the 

 corolla densely hairy with short stiff hairs except at the base. The speci- 

 men in this herbarium which shows these characters most markedly is 

 from a cultivated plant collected by H. Zabel in the Botanic Garden 

 at Muenden, Germany; this plant had been received in 1871 from the 

 Booth Nursery at Flottbeck, Germany, under the name Andromeda 

 tomentosa and is no doubt the plant described by Dumont de Courset 

 under that name; by Kirchner (in Petzold & Kirchner, Arb. Muse. 468 

 [1864]) it was erroneously referred to Xerobotrys tomentosa Nuttall ( = 

 Arctostaphylos tomentosa Lindl. )
