30 Mr. J. Ball on Odontites rubra, with notice of a new species. 
denser and more uniform inflorescence, and the constantly smaller 
fruit appear to supply constant characters. The exserted anthers 
and the shorter floral leaves are sometimes found in O. verna var. 
elegans above described. I have specimens from Tuscany, Um- 
bria, Rome and Naples, the latter gathered by myself at the end 
of September 1845 ; but I have never seen any other than Ita- 
lian specimens, and the plant appears to be unknown in central 
Europe. 
In consequence of the confusion that exists as to the identity 
of the forms which have borne the names EHuphrasia serotina, it 
appears necessary to abandon that specific name, though highly 
appropriate, and in that case the Italian plant cannot bear a more 
suitable name than that of the only author who has clearly distin- 
guished it from its allies. 
Odontites rotundata (n. sp. ?), nobis. 
About ten years ago I received from Professor Henslow a spe- 
cimen marked Bartsia Odontites ? gathered near the Hague, and 
about the same time I was favoured with an imperfect specimen 
gathered on Bepton Common, Sussex, by Miss Plowden, and a 
specimen marked Cambridgeshire without the name of the col- 
lector. These plants appeared to me at the time to differ in many 
respects from the common English plant, but I was unwilling to 
describe them without a fuller acquaintance with the continental 
forms. I am now induced with some hesitation to assign to this 
form a distinct specific name, beg unable to identify it with 
any of the described species. I subjoin a short description :— 
Odontites rotundata.—Stem with numerous elongated branches 
from near the base, (in my specimens) 6-9 inches in height ; 
leaves sessile, lanceolate, crenato-serrate, teeth less acute and 
fewer than in O. verna, floral leaves almost entire, equaling or 
(in my English specimens) shorter than the flowers ; segments 
of the calyx one-third of its length, broadly triangular ; corolla 
rather shorter than in O. verna, upper lip broad, convex, in- 
cluding the anthers, lower lip with three broadly rounded, nearly 
equal segments ; filaments nearly glabrous ; anthers transverse 
with scarcely any glandular hairs; style and stigma nearly 
glabrous ; capsule broadly oval, almost rounded, when ripe 
longer than the calyx. 
Hab. England and Holland. 
In my specimens the whole plant is less hispid, with a softer 
pubescence than in O. verna. The form of the calyx and cap- 
sules, and the nearly glabrous filaments, anthers, style and stigma 
bring this form near to O. lanceolata, Reich. ; but that plant, of
