468 MR. E. G. BAKER ON A NEW SECTION 
4. Gynecium.—The female flower is larger than the male 
flower, but like this latter it occurs in clusters, each containing 
3—4 flowers, and these clusters are sessile upon the trunk of the 
host. The perianth-tube is about as long as the lobes, and is 
entirely adnate to the ovary. The lobes of the perianth are six 
in number. 
The ovary is unilocular, and the placente are 9-12 in number, 
and are long and sinuous. The ovary is so nearly inferior that 
only the summit projects from the enveloping perianth-tube. If 
a transverse section, taken from the very top of the ovary, be 
examined, it will be found to be. spuriously multilocular ; by 
spuriously I mean that there is only one central loculus contain- 
ing placente, but that there are several other smaller loeuli 
which are destitute of placent®, and which are not found in a 
section taken lower down in the ovary (see fig. 5). The ovules, 
which are very numerous, are erect and orthotropous, and have 
only one integument ; the various stages of the development of 
this integument can often be traced in a single section of the 
ovary, the ovules at the base of the placent: being in a younger 
state than those at the apex. The first stage consists of a pro- 
tuberance on the walls of the placenta; then other ovules can be 
seen, with the nucleus projecting like a cone from the encircling 
integument ; and, finally, the integument when fully formed 
appears to consist of two layers of cells. The ovules of this 
parasite differ very considerably from those of Rafflesia, a8 
described by Robert Brown*. In this latter plant they are 
curiously anatropous, with a dilatation at the apex of the funiculus. 
The style is short, solid, and columnar; the stigma is 
capitate, and has apparently as many lobes radiating from an 
umbilicate centre as there are placentas in theovary. The viscid 
surface extends all over the summit and a little down the sides 
of the stigma. There isa dilatation at the base of the style, which 
will be seen represented by two protuberances in the vertical 
section (see Plate XIX. fig. 2). 
As all the specimens of the parasite were gathered at about the 
same date, the fruit and seeds are unknown f. Doubtless the
