700. Poa oraria D. Petrie in Trans. N. Zealand Inst, 1909, XLII 
(1910), p. 196. — Gramen caespitosum, parce foliosum, 40—50 cm altum, 
leve, politum, perenne. — Culmi multi, erecti, glaberrimi, gracilis, a 
basi ramosi, teretes, 2-nodosi, internodiis elongatis, folia longitudine 
aequantes, foliorum vaginis, paene ad imam paniculae partem vestiti. — 
Folia longe vaginantia, vaginae inferiores latae, membranaceae, stra- 
mineae, leviter striatae; ligula vaginam latitudine aequans, oblonga, 
obtusa; lamina teres, erecta, involuta, subrigida, gracillima; leviter striata, 
apice subacicularis. — Panicula strictissima, linearis, + 10 cm longa; 
ramis 3 v. paucioribus, brevibus, teretibus, glaberrimis, paucas spiculas 
sublonge pedicellatas gerentibus. — Spiculae anguste oblongae v. plus 
minus cuneatae, 8 mm longae, 3 mm latae, 4 v. 5 flosculos gerentes. 
— Glumae vacuae subaequales, spiculis tertia parte breviores, anguste 
lineari-lanceolatae, acuminatae, 3-nervatae. —  Glumae floriferae anguste 
lanceolatae, acuminatae, membranaceae, plerumque 5-nervatae, nervo 
medio solo ad apicem attinente, basi parvo pilorum brevium flocco prae- 
dita, in nervis subsericeae, alibi plus minus scabridae. — Palea gluma 
florigera paulo brevior, 2-nervata, nervis delicatule ciliatis: — New 
Zealand: Moist and wet stations at the head of several of the sounds 
of western Otago (Deep. Cove, &c.) Collected by Mr. B. C. Aston 
in mid, — January, 1909; it appears to flower towards the end of 
December. 
101. Uncinia pedicellata Kükenthal in Trans. N. Zealand Inst, 1909, 
XLII (1910), p. 211. — This is based upon a plant collected by D. 
Cockayne on Ruapuke Island, in Foveaux Strait. I have seen no 
specimens, but according to Kükenthals description it is closely allied 
to U. australis, differing mainly in the reddish foliage, narrower spikes, 
obtuse glumes, and obsoletely nerved utricles, which are conspicuously 
longer than the glumes. In U. australis the utricles seldom exceed the 
glumes, and are usually distinctly nerved. 
102. Olearia pachyphylla Cheeseman in Trans. N. Zealand Inst., 1909, 
XLII (1910), p. 216. — O. furfuracea affinis sed foliis majoribus et multo 
coriaceis, capitulis longissimis, involucri bracteis multo numerosioribus. 
— Frutex 1,5—3 m altus, rami robusti, angulati, sulcati. Folia 12,5 cm 
longa, ovata vel ovato-oblonga, obtusa velsubacuta, valde coriacea, supra 
glaberrima, subtus densissime sed appresse sericeo-tomentosa; venis 
reticulatis. Capitula longissima, 1,5—1,8 em longa; involucri bracteae 
numerosae, 35—40, multiseriatae, sericeo-tomentosae, inferiores minutae. 
Flores 7 -10. — New Zealand, North Island: Bay of Plenty, hills at 
Opape, on the road from Opotiki to Torere and Te Kaha; Bishop Wil- 
liams! Flowers in March. — A very remarkable plant. In habit and 
foliage it much resembles O. furfuracea, and when out of flower might 
easily be taken for a robust largeleaved form of that species. But the 
flower-heads are altogether unlike those of O. furfuracea, or of any 
other species, being remarkable for their great length (quite ?/, in.) and 
the number of the involucral scales (35—45), which are imbricated in
