This was reduced to Forster’s G. montana by Sir J. D. Hooker; but Mr. 
N. E. Brown, who has recently 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 recognised 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-subu- 
late calyx-lobes. 
4. G. chathamica, Cheesem. n. sp.—Annual, 6—-12in. high; 
main stem stout or slender, erect, with or without several shorter 
and weaker branches springing from the base and usually decum- 
bent below. Radical leaves variable in size, 3-14 1n. 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, 4-4in. 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 three-quarters the length of the corolla, divided about three- 
quarters way down; lobes linear-oblong, obtuse. Corolla narrow- 
campanulate, divided two-thirds way down; lobes oblong or oblong- 
obovate, rounded at the tip. Ovarv linear-oblong, sessile.—

I consider this to be a very distinct species, to be recognised without any 
difficulty by the peculiar habit, small and broad thin leaves, and small umbel- 
late flowers, with a deeply divided calyx and corolla. A specimen collected by 
Mr. Buchanan at the Lindis Pass, Otago, and another gathered by Mr. H. B. 
Kirk on D’Urville Island may belong to the same species, but they are far more 
copiously branched and have much longer leaves, and are best held over until 
more complete material is obtained. 
5. G. corymbifera, T. Kirk in Trans. N.Z. Inst. xxvii. (1895) 
336.—Usually perennial, but often dying after flowering. Root 
stout, long and tapering. Stems simple or rarely branched from 
the base, stout, erect, terete, 6-20in. high. Radical leaves nu- 
merous, rosulate, 1-4 in. long, +-2in. broad, narrow oblong-spathu- 
late or lanceolate-spathulate, obtuse or acute, narrowed into a short 
or long petiole, blade often channelled above, 1—3-nerved, coria-
