ior row and parietal in the upper one. The
number of ovules in each carpel of the superior row varies greatly, and
they are often, but not always, inserted in two longitudinal ranks, as
is constantly the case in the lower carpels. Double flowers of _Crataegus
Oxyacantha_ present the same anomalies." For analogous instances in
_Digitalis_, see p. 98. See also p. 380, _Saxifraga_.

_Prolification_, p. 120.--A. P. De Candolle, "Organographie Vegetale,"
tab. 40, figures an instance of suppression of one lobe of the ovary in
_Iris chinensis_, and of the presence at the base of the flower of an
adventitious and imperfect flower-bud, as in the _Phlomis_, mentioned at
p. 119.

_Monoecious Misleto_, p. 193.--In this specimen, exhibited at one of the
meetings of the Scientific Committee of the Royal Horticultural Society
in 1869, there were both male and female flowers on the same bush. The
plant was of the male sex, with numerous long slender whip-like,
somewhat pendulous, branches bearing comparatively large broad yellowish
leaves, and fully developed male flowers at the end. From the side of
one of these male branches, near the base, protruded a tuft of short,
stiff branches, bearing small, narrow, dark green leaves, ripe berries
and immature female flowers. There was no evidence of grafting or
parasitism, of the female branch on the male, the bark and the wood
being perfectly continuous so that the only tenable supposition is that
this was a case of dimorphism.

_Adventitious leaflet and pitcher_, see pp. 30 and 355. In a species of
_Picrasma_, in which the leaves are impari-pinnate and spread
horizontally, an adventitious leaflet was observed to project at right
angles to the plane of the primary leaf. It emerged at a point nearly
corresponding to that at which the normal pinnae were given off. The
appearance presented was thus like that of a whorl of three leaves,
except that the shining surface of the adventitious leaflet,
corresponding to the upper face of the normal leaflets, was directed
towards the axis, _i.e._, away from the corresponding portion of the
neighbouring pinnae, while the dull surface, corresponding to the lower
part of an ordinary leaflet, looked towards the apex of the main leaf,
or away from the axis. In one instance, a stalked pitcher was given off
from the same point as that from which the supernumerary leaflet
emerged, the pitcher being apparently formed from the cohesion
(congenital) of the margi
