. distinction ; in his second paper he modifies his former opinion, 
and considers that he attached too great weight to the comparative 
size of the corolla, which he now believes to ‘be variable ; he there- 
fore includes eh form of the leaves, remarking that this character 
sufficed for to retain as species H. minima, I’. ee. 
and I, Selouseictna, He now alludes to the greater importance 
the presence or absence of glandular hairs, and upon this, “eamarcto 
with the form of the leaves, he founds three species, subdividing 
each into three subspecies by the comparative size of the corolla. 
I believe Mr. Soyer-Willemet is right in attaching great importance 
to the i of the leaf, but he attaches too little to the corolla, if 
ficial ones, and so are his subdivisions or Scbasbeae As regards 
the parts from piditals the sce ria should be drawn, and the 
what as follows :—(a) The direction “of the style ing flowering 
(first noticed, I believe, by Kerner); (b) the form of ‘the leaves and 
bracts, also the form, di , and r of eth of bot 
ese; (c) the nature of the hairs on the leaves and calyx; (d) the 
form and colour of the corolla; o& the mode of branching; (f) the 
form of the calyx and capsule, & 
Y Own conclusion is that all the European forms — which 
Tam as yet acquainted (omitting H. grandiflora Hochst. extra- 
European) are members of a single polymorphic species, ‘ind that 
none of these members can be ranked as of a higher grade than a 
Subspecies. But I believe that these naturally arrange themselves 
into eight groups; and the main object of the present paper is to 
give the diagnosis of these, each of which I have designated by the 
name of a well-known species contained within the group. The 
adoption of this nomenclature is convenient because the names ei 
once call to mind the salient features of the groups, which are— 
Orricinates; I]. Montane; III. Tricuspmarz; IV. Nemorosz; 
V. - VI. Sauissurcenses; VII. Parvirtorm; VIII. Mr-
