and in none of the many specimens which I collected do I 
find any deviation from this structure. "The sporangia alen ` 
differ a little from those of Anemia, in having their upper | 
half covered with the annulus, which in Anemia seldom 
covers more than a third or a fourth. In venation it | 
agrees with those species of Anemia which have it flabellate, | 
for I find, in that genus, at least three distinct kinds of ; 
venation, which affords a strong argument against the use of ` 
peculiarity in this structure alone as a generic distinction, i 
without a well marked difference in the fructification or babit. — 
The same peculiarities which distinguish Trochopteris from 
Anemia, distinguish it from Schizea, Lygodium, and Mohria. 
Its station is evidently between Anemia and Mohria.

1. Linaria Bauhini. 
So long ago as the year 1830 or 1831, I found a species of 
Linaria, not described in the British Flora, growing inter- - 
mingled with L. repens and L. vulgaris, in hedges a short 
distance from Penryn, by the road to Truro. Being a very - 
young botanist at that time, I was unable to make out the — 
plant; but conjectured that it might be a hybrid between the 
two species with which it was associated, since, in general ap- - 
pearance and more minute characters, there was an interme — 
diate resemblance to both of them. Unfortunately, I had | 
then not learned to collect with botanical judgment, and : 
picked only the flowering branches, without taking the lower S 
part of their stems; and the specimens having been almost 
immediately packed up for traveling to a distance, thes ; 
colour was soon lost through damp. Most of these speck ` 
mens were distributed to different botanical correspondents; —
