quite typical H. prenanthoides.” — J. G. Baker.

Vaccinium sp. An unnamed shrub sent from Audley Dingle, 
Staffordshire, by Dr. F. Arnold Lees, is one of the North American 
species of Vaccinium , but the specimens are too imperfect to allow of 
a more definite determination. 
Gentiana germanica, Willd. Chalky banks, Crowell Hill, Oxon, 
Sept., 1883. Crowell Hill is one of the Chiltern range, and within 
two miles of the Bucks border. The plant occurred abundantly on 
very bare chalky slopes, but although extremely variable in size and 
number of flowers, yet the size of flowers seemed fairly constant. I 
did not notice any great difference in size of corolla lobes, nor did 
the length of germen seem worth consideration. The leaves are 
broader than those of A??iarella, and the colour considerably lighter, 
more blue than purple, and often lilac. G. Amarella grew with it 
plentifully, but it requires persistent search to find one in flower, 
whereas G. germanica was in profuse blossom, scarcely over its prime. 
There must be ten days difference in the time of flowering of the two 
plants. A few plants were found with only four lobes to the corolla. 
While in the greatest abundance on slopes of almost bare chalk, still 
others were scattered in the grass, and some few were found on the 
tertiary above the chalk. This hill yields, in its only Oxford locality* 
Cephalanthera ensifolia. Gentiana germanica had not previously been 
recorded for Oxford. — G. C. Druce. 
Cuscuta europcea , Murr. Moleside, Esher, Surrey, Sept, i, 
1883. — J. Groves. 
Mentha sylvestris , L. mollissima. Bank of the Wye, Great 
Doward, Herefordshire. Aug. 27, 1883 . — Augustin Ley. Mr. 
Baker thinks this is not the var. mollissima; he looks upon it as 
typical M. sylvestris .
