Arrinitiss. These differ from the preceding by the adhesion of the ovaries with the sides 
of the calyx and more or less with each other. “ The fruit is always a pome; that is, it is 
made up of a fleshy calyx adhering to fleshy or bony ovaries, containing a definite number of 
seeds. Pomeae are principally distinguished by their ovules being in pairs and side by side 
while Rosaceae, when they have two or more ascending ovules, always have them one above the 
other. Cultivated plants of this order are very apt to produce monstrous flowers which depart 
sometimes in a most remarkable degree from their normal state: nor can any order be more 
instructively studied with a view morphological inquiries, particularly the common pear when in 
blossom. A remarkable permanent monster of this kind with 14 styles, 14 ovaries anda calyx, 
with !0 divisions in two rows is described in the Revue Encyclopedique, thus exhibiting a tend- 
ency on the part of Pomeae to assume the indefinite ovaries and double calyx of Rosaceae, I 
have seen a Prunus in a similar state’—Lindley. 
Sub-order AmyepaLeak. The Almond tribe. 
“ Calyx 5-toothed, deciduous, lined with a disk ; the fifth lobe next the axis. Petals &, 
perigynous. Stamens 20, or thereabouts, arising from the throat of the calyx, in ewstivation 
curved inwards ; an/hers innate, 2-celled, bursting longitudinally. Ovary superior, solitary, 
simple, l-celled ; ovules 2, suspended ; styles terminal, with a furrow on one side, terminating 
in a reniform stigma. Fruit a drupe, with the putamen sometimes separating spontaneous 
from the sarcocarp Seeds mostly solitary, suspended, in consequence of the cohesion of a 
funiculus umbilicalis, arising from the base or the cavity of the ovary, with its side, Embryo 
straight, with the radicle pointing to the hilum; cotyledons thick; albumen none. Trees or 
shrubs, Leaves simple, alternate, usually glandular towards the base. Stipules simple, mostly 
glandalar. Flowers white or pink. Hydrocyanic acid present in the leaves and kernel.” 
Arrinitizs. To this sub-order all our stone fruit belong: the sloe and its numerous deriv- 
_atives, the almost endless variety of plums: the cherry in all its various forms: and the almond 
from which, according to some, cultivation has elicited the various kinds of peaches, ines, 
and apricots, but which others consider distinct species. They are distinguished from the two 
preceding orders by the fruit being a drupe (a succulent stone fruit) by their bark yielding gum, 
ut most remarkably by the presence of Prussic or Hydrocyanic acid. To Leguminosae they 
approach through Detariwm which has a drupaceous fruit, but are separated by their regular 
“petals and stamens, by the position of the odd sepal and by the presence of Prussic acid “ It 
‘is not a little remarkable that here,where we have a close approach to the structure of Mimoseae, 
in Leguminosae, we have also the only instance among Rosaceae of an approach to the property 
possessed by that sub-order of the bark yielding gum; the peculiar astringency of some species 
‘Is also analogous to that of Acacia cafechu and the like.” Lindley, 
: anges Geocrarurcan. Distaisution. None of the species of this sub-order are known to exist
