MR. J. MIERS ON THE FAMILY OF TRIURIACEA. 45 
Mr. Gardner, who at first was much struck with their resemblance to Triuris and his Pel- 
tophyllum ; but on account of their manifest affinity to Sciaphila he renounced that idea, 
and in some observations which he annexed to Captain Champion’s memoir, he suggested 
their position as being in Artocarpee, that being the station assigned to Sciaphila by 
Endlicher. Captain Champion, on the contrary, was more inclined to place them in Urti- 
cace@, among the Moree, because of their aggregated carpels on a common receptacle. 
The first. plant described by Captain Champion is the Hyalisma ianthina; it greatly 
resembles Triuris hyalina in habit, and agrees with it, and with Hevuris, in being dicecious. 
The perianthium is cup-shaped at its base, with the border divided into eight pointed seg- 
ments of equal size, being valvate in estivation, with the apical points inflected in a ver- 
tical umbilicus. The male flowers have four stamens placed opposite each alternate seg- 
ment, and almost sessile upon a fleshy prominent disc, as in Triwris; but the lobes of the 
anthers, instead of being distinct, are here confluent, at first four-celled, but afterwards 
bursting into two valves, by a transverse line across the apex on one of the cross pollini- 
ferous dissepiments. The ovaria are numerous and aggregated in the female flowers, but 
the style, instead of being subterminal and sublateral, as in Triuris and Hexuris, is here 
nearly basal upon the ventral face. The whole plant, as in those genera, is covered with 
prominent vesicles, forming a bullulato-cellular epidermis. The more important con- 
sideration of the structure of its seed will be noticed in a subsequent page. 
The second plant described by Captain Champion, under the name of Aphylleia eru- 
bescens, is very similar in general habit and structure to Hyalisma ianthina, differing only 
in the number of the segments of the perianthium, which are six, as in Sciaphila, with six 
stamens opposite to them in the male flowers. The carpels in the female flower do not 
differ much from those of Hyalisma, excepting that the style is shorter and ciliately fringed, 
not long, simple and pointed. In all the pistilliferous flowers I have seen they are con- 
stantly somewhat polygamous, with three or fewer stamens, placed opposite the alternate 
segment, among the outer row of carpels; but whether they are polliniferous or other- 
wise, I have not been able to determine. The structure of the seed is exactly that of Hya- 
lisma. 
In Sir William Hooker's herbarium I found a plant of Mr. Cuming's collection from 
the Philippine Islands, that bears a great resemblance to Aphylleia erubescens: like it, 
the perianthium is 6-cleft, but the segments are not altogether glabrous, being furnished 
within at the apex with a tuft of long articulated hairs, and the stigma is radiate with 
similar cilia. I have noticed that all the flowers here are hermaphrodite, the three sta- 
mens being intermixed with the carpels, as in Captain Champion's plant above mentioned. 
The fruit is utricular, and of similar structure. 
In the same herbarium is another plant, found by Purdie in Venezuela; it agrees with 
the two plants last mentioned in the form of its perianthium, and in having its flowers 
hermaphrodite, that is to say, with only one or-two stamens, placed on the margin of a 
clustered heap of carpels: here, however, the segments are alternately somewhat narrower, 
the broader segments only having ciliate margins, but all are furnished at the apex inter- 
nally with long articulated hairs, and the segments, as well as the braets and bracteiform 
leaves, are marked with long red spots, as in the two preceding species.
