a small branched sub-corymb ; pedicels about 1 line long. 

 Sepals glabrous, smooth, black. 



Hab. Open lands ; Taupo : 1885. 



Obs. I. This plant is nearly allied to D. aurlculata, Backh., 

 and also to D. peltata, Sm., differing, however, from the 

 former in its lower leaves being not peltate with long pe- 

 tioles, and from the latter in its lower leaves being decurrent 

 on longer and narrower petioles, and from both in the largely 

 laciniate margins of its leaves, their greatly extended angles, 

 and their peculiar orbicular venation. -Its flowers are also 

 differently disposed, not being racemose and with smooth 

 sepals. 



II. I received this plant several years ago, with others, 

 from Taupo ; and from its being immature I refrained from 

 describing it, as I had been led to expect more complete speci- 

 mens. It stains the drying-papers red, like others of its 

 genus ; and I believe, from its long slender simple and broken 

 tap-root, that, like some of them, it also arises from a bulb. 

 Having but a single specimen, which, though not fully de- 

 veloped, is entire, allowance must be made for not giving any 

 description of its floral parts. 



Order XXIX. Onagraeie^. 

 Genus 2. Epilobium, Linn. 

 1. E. nanum, sp. nov. 



Plant very small, glabrous, erect, 2|-in. high ; stem simple 

 red slender, minutely bifariously puberulent on the basal por- 

 tion ; leaves few, opposite, distant 2|- lines apart on stem, 

 linear-lanceolate, sub 2 lines long, subacute, with 1 (mrely 2) 

 very small blunt teeth at lateral margins, thickish, green, 

 subpruinose, tapering, the basal half of midrib below red pro- 

 minent ; petiole very short, stout. Flower solitary, axillary 

 near top less than 1 line long ; corolla perfect but unex- 

 panded, white ; calyx shorter than corolla, grey, lobes sub- 

 acute with red margins, and a red central line ; capsule T;%in. 

 long, slender, glabrous, green, scarcely tetragonal ; peduncle 

 j-%in. long, thickly puberulent with short white curved hairs. 



Hab. Among other low herbage (as Nertera, Utricular ia, 

 Hydrocotijlc, &c.) ; marshy spots, high land base of Mount 

 Tongariro, Taupo district ; January, 1893 : Mr. H. Hill. 

 (Eeceived in living tufts, as dug up.) 



Obs. Of this little plant I have only obtained two speci- 

 mens, both alike in size, &c., but one only bearing a flower. 

 The regular shape of their small narrow leaves, and their 

 strictly-erect growth, the simple stem without any basal 

 branches, or root-stock buds, serve to mark it as being distinct 

 from the other small indigenous species of this genus, which
