Sahhagia, 
Flowers licrmaplirodite. without hractcoles. 
Calyx minute ; its tube at last cartilagi- 
nous, circumcised at the base, terminated 
by two, rarely three, horns of unequal 
lengtli, each of which bearing at its ex- 
tremity a vertical reuate scarious wing. 
Anthers two-celled. Style short. Stig- 
mas 2, capillary. Caryopsis depressed, 
lodjjcd in the upper part of the calyx-tube. 
Pericarp membranous, distinct. Seeds 
horizontal, depressed with a membranous 
testa. Embryo jjeripherical, almost annu- 
lar. liadicle centrifugal, adscendent. 
Albumen scanty, central, mealy. 
In naming this genus I intended to establish 
a lasting scientific record of the services 
rendered to South Australia by B. Herschel 
Babbage, and likewise to express my 
veneration for tbe philosoper whose cele- 
brated name the South Australian explorer 
inherits. 
The genus Babbagia differs from Kochia, to 
which it approaches nearest, in the number 
and direction of the fruit-wings. The 
S resence of the latter distinguishes it from 
[lentropsis. 
Bahhagia dipierocarpa. 
Stuart’s Creek, Elizabeth Creek, Weelpe- 
deroona. 
A perennial, probably shrubby plant, almost 
or entirely glabrous, sometimes with 
bearded axils of leaves and flow'ers. 
Leaves narrow or lanceolate aemicylin- 
drical, alternate, sessile, long. 
Flowers, axillary, solitary, crowded in teS*- 
minal spikes. Calj’^x b<>arded at its vertex, 
the tube separating transversely from its 
almost orbicidar or patellar base, and from 
its short somewhat conical axis, 1"' long, 
glabrous, constricted and perfectly closed 
in the middle, concealing the caryopsis m 
its upper division. Base and axis of cal3rx 
persistent. One of the calyx horns very 
short or even obliterated, the other more 
elongated, about i'" long and includ- 
ing the radicle. Wing-lik^appendages 
vertically surrounding the calyx, of equal 
size unless the third one should be dimin- 
utive, glabrous, pale or pink, membranous, 
transparent, affixed in its sinus, not much 
longer than 1'", with numerous radiating 
veins. Style somewhat ^^■oolly towards 
the stigmas. Testa glabrous, yellow- 
brown.

Anguillaria dioica, E. Br. pr. 273. 
One of the most common plants of South 
Australia. 
There occur also in the collection some in- 
complete specimens, which appear refer- 
able to A. biglandulosa and A. monantha. 
But unless more satisfactory marks of 
distinction between these species are dis- 
covered, we may safely regard them as 
playforms of A. dioica. •
