s might be supposed to elaborate their own from
that of the stock.

There is another very remarkable circumstance connected with the most
typical leafless parasites, in their very frequent limitation to the
genus Cissus, on which perhaps all Rafflesiaceae and Cynomorieae are
exclusively found.

My chief reason for supposing Sarcocodon to be Monocotyledonous, or
rather Endogenous, is the ternary division of its parts, and if my
supposition be correct, it tends to establish, if indeed other ample
evidence did not exist, the great permanence and consequent value of this
numerical character.

And with respect to Sarcocoidalis I shall adopt the same opinion, if I
find on enquiry that a binary number, and imperfection of the female as
compared with the male, are more characteristic of Endogenous than of
Exogenous growth. This same genus I consider in both these characters to
allude to some analogy with one or more Acrogenous divisions.

The establishment of the order of Rhizanths, as well as that of
Gymnosperms, I consider as a retrograde step in Botanical science. It is
totally opposed to all sound principles of classification, and is a proof
that, in the nineteenth century, arbitrary characters are still sought
for, and when found are obstinately maintained.

Even in the arbitrary character, which is considered as destructive of
all their other claims to ordinary vegetable rank, there is no unison
whatever, for Rafflesiaceae have ordinary ovula, while Sarcocoidalis very
extraordinary.

The amount of testimony proving their analogy in germination to be with
Acrogens, must be very strong before I am convinced that plants with
perfect ovula as Rafflesia, etc. germinate from an indeterminate point,
the existence of an aperture in the coats, points in the most marked
manner to some part representing a radicle. With the exception perhaps
of Sarcocoidalis, these plants differ in no respect whatever from other
Phaenogamous vegetables; we have instances of the same parasitical
growth, and instances of the same apparent want of a radicle or
homogeneousness of embryo, and in the structure of the parts of the
flower there is tolerably absolute general identity.

It may be worthy of remark, as tending to prove the soundness of Mr.
Brown's views with regard to the affinity of Rafflesia with Aristolochia,
that a certain large and fleshy flowered species of the latter genus has
the same putrescent smelling flowers.
