286 MR. T. KIRK ON RECENT ADDITIONS 
cent or hairy, with long subulate teeth; the corolla-tube is small, 
scarcely exceeding the calyx in length, the mouth deeply two- 
lobed. 
Our plant fills the ditehes by the roadside, where it attains the 
height of over 2 feet. In moist places in the adjacent forestit is 
much smaller. It is called “turpentine ” by the settlers. 
POLYGONUM PROSTRATUM, R. Br.—A much-branched, pro- 
strate, suffruticose plant, the branches rooting from beneath, in 
the present specimens 6"-10" high; the young branches and 
leaves sparingly clothed with rather long white hairs. Leaves 
lanceolate, narrowed into a short petiole 1” long; stipules 
sheathing, ciliate. Spikes axillary or E short branch- 
lets, sessile or shortly pedunculate, 4” long. Perianth small, 
becoming enlarged after flowering. Stamens 6. Nut convex, 
black, faintly reticulated. In several places by the Wairarapa 
Lake (H. B. Kirk). 
Juncus PAUCIFLORUS, R. Br. (not of 7. Kirk) —Although 
somewhat local, this species occurs throughout the colony, and 18 
abundant in Stewart Island; it is generally known to New- 
Zealand botanists as Juncus communis, var. hexagonus ; it is, 
however, distinct from that species, although of similar habit. 
The panicle is lax, consisting of a few slender branches ; flowers 
few in number and small; perianth-segments acute; stamens 6 ; 
capsule ovoid, faintly angled. The culms are usually slender 
and the sheaths at the base very short. It appears to have been 
collected in New Zealand by Banks and Solander. 
Juncus BREVIFOLIUS, T. Kirk.—J. pauciflorus, T, Kirk (not 
of R. Brown)—In the * Transactions of the New-Zealand Insti- 
tute,’ vol. ix. p. 551, I described this small species under the 
name of J. pauciflorus; but as that name had been applied by 
Brown to the plant mentioned above, I p to term my plant 
Juncus brevifolius. 
It is distinguished from all New-Zealand species by its rosulate 
leaves, slender, naked, erect culms, and sessile flowers. At present 
it has only been observed in the Broken-River basin, Southern 
Alps, alt. 2000 feet. 
CENTROLEPIS MONOGYNA, JBenth.— Alepyrum monogynum, 
Hook. f.—This moss-like plant occurs in swampy places at an 
elevation of 3000 feet in Arthur's Pass, whereit was observed by 
the writer in 1877, when specimens were distributed under the 
MS. name of Alepyrum viride. 
It forms large patches scarcely 4” in height when in flower.
