a 
ROSA ACICULARIS. AS 
calyx naked, elliptical; sepals very narrow, somewhat 
divided, hairy, thrice as long as the tube; petals obo- 
vate, emarginate, spreading, shorter than the sepals ; 
disk broad, a little elevated; styles hairy, distinct, 
their ends exserted and spreading. Fruit obovate, with 
a neck, yellowish orange, naked, somewhat oblique, 
crowned with the connivent sepals, which are thickened 
at their base. 
An interesting addition to the spinosissima tribe, 
introduced from Siberia by Mr. Bell. From plants 
communicated by the late Mr. Donn to Mr. Sabine, it 
appears to be the R. kamchatica of his Hortus Canta- 
brigiensis. From the three preceding species inequality 
of prickles distinguish it; it is readily known from the 
rest by its greater size and glaucous, rugose leaves. In 
the former respect it is surpassed, indeed, by R. Sabini, 
but the strong prickles of that plant, which are falcate 
when mixed with sete, and pugioniform when without 
them, make it impossible that they should be con- 
founded, not to mention their entire dissimilarity in 
other respects. 
It is the first Rose that comes into leaf, and at that 
period is remarkable for the yellow, as it were blanched, 
colour of the nascent leaves.
