This differs from the type in flowering through the winter, in its
being a stiffer and much more branched plant, especially in the upper
part, where there is a quick transition in the 8ize of the leaves of the
main stem, which are firm in texture, short and broadly ovate, to
those of the copiously branching ramifications on which the leaves
are less than half the size of the lower ones. The flowers are smaller
than those of the type, both as regards sepals and petals. The stamens
are not more than seven in number. Locality under trees and on
wall-tops, Countess Wear, S. Devon. W. S. M. D'UltBAN, Nov. 1924.
One may add that the sepals are less strongly nerved, and when fresh
are barely discernible. It forms an approach to A. pentandr-a
Dufour, from which it differs in its laminae and their nerves being
ciliate, in the larger number of (7 as against 5) stamens, in the less
strongly marked (when there are more than three) leaf-nerves, and
in the smoother seeds; from Jioehringia e'recta MarL-DonoB
(Pl. Tarn. 106, 1864) it differs 111 being less pubescent,
the upper leaves are spreading, the upper branches are
not erect, nor IS the plant simple, stiff and slender. Rouy
& Foucaud (Pl. Fr. Ill., 256) cite the E1/,{j. Bot. plate,
1483, for ill. pentandra, but in error, as the leaf-nerves are shown to
be ciliate. In the details of the flower added in the third edition (t.
2:34) the flower has ten stamens. A. pentandra may be found in
Britain, indeed see Camb. Pl., where Mr Carter collected a plant in
Devonshire" which seemed to be it," but of which nothing more has
been heard. It may be added that the name trinervia is misleading,
as the nerves valY from 3 to 5 in number. G. C. DRUOE.
396. A. VEHNA L. See Rep. B.E.C. 31, 123. Mr C. C. Lacaita
writes that " in Italy the plant is quite indifferent as to soil, and
certainly knows nothing about lead." Its distribution in Englanf1
is discontinuous, and it has yet to be proved that lead is found in all
its habitats. It must also be borne in min
