310 WILSON’S OBSERVATIONS. 
in Engl. Fl. vol. iv. having two barren flowers on the same 
stalk. 
12. Salix reticulata. Craig Calleach, July 4, 1827.  Fila- 
ments hairy. Nectary in about 8 deep lobes surrounding 
the germen or anthers. i 
13. Viscum album. Berries examined December 31, 1828. 
The seed has most commonly two embryos, in some cases 
three, and occasionally one only. I consider two the most 
usual number; for as the plant is dicecious, and its propaga- 
tion by seed rather precarious, I think it probable that the 
two embryos may produce the barren and fertile plants, 
designed to grow together. Embryo with two cotyledons, 
the end of the radicle thickened and abrupt, just protruding 
from the albumen. The skin of the seed is thin. Berry 
forming two concentric layers of viscous matter, the inner 
one closely adhering to the seed after forcibly bursting the 
berry. 
14. Rhodiola rosea. Wales, June 27, 1828. Calyx of the 
barren flower with 4 linear segments. Petals four, linear, 
larger than the calyx segments. Four of the filaments 
attached to the bases of the petals, between which and the 
abortive germens are 4 oblong, notched, flattened, yellow 
nectaries, Anthers at first reddish, afterwards blackish-green, 
two-celled, erect, ovate, with 4 furrows, the valves separating 
at two opposite furrows. 
15. Juniperus communis. Gloddaeth, May and June, 1828. 
Calyx ofthe fertile flower imbricated. Corolla, of one petal, 
campanulate, in three deep roundish-ovate, concave segments, 
permanent, at length united into a fleshy covering to the 
seeds. Pistils three, superior. Germen ovate, gibbous at 
the back. Style short. Stigma two-lipped—the germen has 
a single rudiment at its base. Seeds oblong, angular, bony, 
atemhdd with the short permanent style. 
16. Juniperus nana. Glyder Fawr, June 24, 1818. The 
calyx-scales more lax than in the last. Barren fl: Calyx 
apparently formed of two rows of scales, 3 in each row. 
Anthers 3, 4, or 5 together, fixed to the back of each inner
