size of the plant, 4-2in. long, white. Calyx large, more than ? the length 
of the corolla, cut down almost to the base into 4 narrow-linear subulate 
lobes, which are sharply acute. Corolla divided to about # of its length 
into ovate-lanceolate acute and apiculate veined segments. Stamens 3 
the length of the corolla. Capsule exceeding the corolla when mature.

Much more complete material is required before a really good description can be 
prepared. It is quite possible that it may be simply a large state of G. lineata. 
4. G. Grisebachii Hook. f. in Hook. Ic. Plant. (1844) t. 636.—A slender 
much or sparingly branched annual herb; root weak, often filitorm ; 
stems branching from the base, very slender, decumbent or suberect, 
3-14 in. long, rarely more. Lower leaves narrowed into slender petioles 
as long or longer than the blade, $-lin. long, spathulate or oblong- . 
spathulate, rather thin and membranous, obtuse ; cauline usually smaller, 
remote, sessile or shortly petiolate, oblong or ovate-oblong, obtuse or sub- 
acute. Flowers few or many, terminal and solitary at the tips of the 
branches, rather small, 4-2in. long, white. Calyx divided ?-way down 
or more, often somewhat angled at the base ; lobes linear or linear-subulate, 
acuminate, midrib distinct. Corolla narrow-campanulate, divided more 
than half-way down; lobes narrow-ovate or oblong, acute. Stamens 
about 2 the length of the corolla. Ovary linear-oblong, often shortly 
stipitate—Cheesem. Man. N.Z. Fl. (1906) 448. G. montana Hook. f. Fl.

Var. Matthewsii Petrie. —Stems stouter and more erect. Leaves broader, more 
oblong. Flowers rather larger; calyx-lobes shorter and broader.—G. Matthewsii

Var. novae-zealandiae.—Smaller and more slender, 1-5in. high. Leaves 4-4 in.

This was reduced to Forster’s G. montana by Sir J. D. Hooker; but Mr. N. E. 
Brown, who has done me the service of examining Forster’s types preserved in the 
British Museum and at Kew, informs me that it is quite distinct, and in no way 
resembles G. montana. It may be recognized by the usually much-branched slender 
and wiry sparingly leafy stems, small rather thin leaves, small flowers terminal and 
solitary on the branches, and linear-subulate calyx-lobes. 
5. G. chathamica Cheesem. Man. N.Z. Fl. (1906) 449.—Annual,. 6-12 in. 
high ; main stem stout or slender, erect, with or without several shorter 
and weaker branches springing from the base and usually decumbent 
below. Radical leaves variable in size, $-14in. long, narrowed into short 
petioles or almost sessile, ovate-spathulate or oblong-spathulate to broadly 
oblong, obtuse, rather thin; cauline 1 or 2 pairs, ovate or oblong, sessile 
with a broad often almost cordate base. Flowers small, 4—-Sin. long, 
white, sometimes veined with pink, arranged in several 3—12-flowered 
umbels terminating the stem and its branches, each umbel with an involucre 
of 3-5 whorled bracts; pedicels usually longer than the bracts. Calyx 
about # the length of the corolla, divided about 3-way down ; lobes linear-
