THLASPI VIRENS.—The little alpine mentioned 
by Mr, Webster on р. 22, as abounding on the hil- 
0 mine debris, above Llanrwst on 
Carnarvonshire side of the Conway, is 
Thlaspi occitanicum (Jordar, Sowerbys Bot., е 
147). A closely allied form, Thlaspi virens 
(J ordan, patan erby's Bot., t. 148), is a ча abun- 
dant in similar situations near Matlo Some

ster will t fourths lime 
stone debris and one-fourth soil—a mi ixtu ure in which 
many alpines flourish—I think he will eain his 
opinion about ет being hard to cultivate. І сап- 
not distinguish one from the other, and Bentham 
includes both sid er Thlaspi — (Linnzus). С.

INSECTS d FROST.— Тһе writer of the inter-

I am disposed to think it belongs to the category 
of popular errors, or, if not, needs 
has yet been given. 'The previous winter 
was decidedly a rd one, d we had much 
intense frost, and ye will be remembered that 
rarely have queen or thes asps been more abun-
