glandular. The styles are very slightly exserted and the 
uppermost portion does not gradually widen upwards as 
in E. ciliaris, but it is abruptly capitate as in E. Tetralix, 
and the ovary is downy, not glabrous, but I cannot find on 
the whole plant a single ovary which has come to maturity. 
The character by which the hybrid appears to be differ- 
entiated from its allies the most readily is taken from the 
anther, and more particularly by its awn-like appendages. 
The anthers of E. Tetralix possess two awns which are 
equal in length to the lobes of the anther, while the filament 
is united to the anther at the back just above the base of the 
lobes. The anthers of E. ciliaris are also attached by their 
bases to the fi] ament, but there is no trace of any awns. In 
the hybrid plant however, the attachment of the filament is 
higher up the back of the papillose anther, so that the two 
lobes project much more than in the parent plants; from 
each side of the filament at its junction v/itli the anther, 
there rises a slender awn whose leugth is only one-fourth 
that of the anther, and these two awns do not project beyond 
the lobes as they do in Erica Tetralix. 
From a comparison of the specimens exhibited, it will be 
seen that Mr. Nix’s plant comes nearer to E. ciliaris than 
do Mr. Watson’s, particularly in the infloresence ; but they 
agree perfectly in the character of the av/ns of the anther, 
as noted above. In habit it seems to have some affinity 
with E. Machaiana, and it is nearer E. Tetralix than E. 
Ciliaris in this respect. 
The habitat of the hybrid plant is described by Mr. Nix 
as decidedly boggy, and his observation of the Cornish local- 
ities of E. ciliaris leads him to conclude that it also fiour- 
ishes best in a similarly moist station. Dr. Syme on the 
other hand gives '' sandy heaths ” as the character of the 
station of E. ciliaris. Erica Tetralix loves boggy land, and 
this seems to be the character of the station where Erica 
tetralici-ciliaris flourishes in some abundance.
