916 PROCEEDINGS OF SECTION G 
UMBELLIFER. 
Trachymene australis, Benth.—‘‘ Wild Parsnip.” 
A rather coarse plant, with leaves either radical or at the base 
of the stem, and hispid, with long hairs. Flower stalks long and 
distant, each bearing an umbel of numerous, small flowers. Stalks 
on the main stem, sometimes several together, so as to form a 
large, irregular, compound umbel. The whole plant is acrid. 
COMPOSITAE. 
Myriogyne minuta, Less.—“ Snuff Weed.” 
A prostrate, branching plant, with slender stems, more or less 
clothed with short, woolly hairs. The oblong, toothed leaves 
rarely exceed half an inch in length, and are often much shorter. 
Flower heads very small, solitary, and mostly leaf-opposed. The 
whole plant has a slight pungent scent when bruised. 
GOODENOVIER. 
Velleia macrophylla, Benth.—* Yellow Poison Plant.” 
A glabrous, erect, leafy, branching plant, attaining sometimes 
a height of 4 feet. Stem leaves from 2 to 6 inches long, toothed, 
and narrowed into a long stalk. Flowers rather large, borne in 
axillary panicles. There are one or two forms of this fine plant. 
CAMPANULACE. 
Lobelia heterophylla, Labill.—* Blue Poison Plant.” 
An erect growing, annual plant, with very variable leaves, the 
lower ones sometimes pinnatifid with a few, narrow, linear lobes, 
or obovate and deepiy cut; the upper ones small, linear, and 
entire. Some forms, however, have oblong-linear, obtuse, almost 
entire leaves. Flowers rather large, in a loose, one-sided raceme. 
The oblique capsule is full of small, winged seeds. Some 
forms of this species having entire leaves resemble Jsotoma 
brown, G. Don., Syn. Lobelia hypocrateriformis, R. Br. ; but 
besides other minor differences the anthers of ZL. heterophylla are 
all tipped with a dense tuft of short bristles, while the anthers 
of J. brownii are always glabrous. 
Isotoma brownii, G. Don.—“ Poison Plant.” 
A glabrous, erect, simple or slightly-branched annual, rarely 
exceeding 1 foot in height; with narrow leaves, usually from 
half to one inch long. Flowers often numerous, in a loose, one- 
ided raceme. The oblique seed-vessel is from a quarter to half 
an inch long.
