Santalum cunninghamii, from the close similarity of its foliage to Olea 
montana and O. lanceolata, is often mistaken for them in districts where it is 
plentiful, but a cursory examination of the flowers or fruit is sufficient to 
prevent the error. On the other hand, Olea cunninghamii is the Santalunm 
cunninghamii of Buchanan’s list of Wellington plants, and its wood has been 
distributed from the Colonial Museum under the name of Santalum. It is, 
however, very rarely that sandalwood forms a trunk of 9” in diameter; most 
frequently it is no thicker than a man’s wrist, and south of the Taupo 
district it is usually reduced to a mere bush, 5 or 6 feet in height. 
The following key to the species of Olea may be found useful :— 
A. Leaves rough. 
i. Leaves oblong or elliptic acuminate, racemes glabrous -- 0. apetala. 
a ate, racemes tomentose .. ‘ .- 0. cunninghamii. 
B. Leaves ae 
3. Leaves lanceolate acuminate, perianth segments linear, acute _O. lanceolata. 
4. Leaves linear lanceolate, perianth segments broad, obtuse .. 0. montana.

Triodia exigua, D.s. 
Danthonia pauciflora, Buchanan, Grasses of N.Z., t. xxxvi. B., not of R. Brown. 
A smatt grass forming a compact swart, root creeping, leaves tufted 1° 
long, filiform, rigid, involute, pungent, glabrous, mouth of sheath clothed 
with a minute pencil of hairs, ligule 0. Culms 1’-2" high, slender, naked 
above. Panicle reduced to a single spikelet, or rarely two when the lower 
— is ' pedicellate. Spikelets 2-8-flowered, empty glumes longer than 
g, obtuse, flowering glumes 8-toothed at the apex, ciliate, nerved. 
Palea notched at apex. Caryopsis free. 
Hab.—South Island: Broken River Basin, Canterbury, on terraces, 
2,500-8000 feet; terraces of the ae Waimakariri, 1,600-2,500 feet; 
Mount St. Bathans, Otago—D. P. 
Mr. Enys and myself saat a specimens of this grass several 
years ago, but as the specimens were far advanced, little more than the 
outer glume remaining, it was not possible to make out its affinities. Last 
year Mr. Enys visited the locality and kindly sent me a supply of gore 
specimens, I am also indebted to Mr. Petrie for good specimens from 
Otago. In his “Indigenous Grasses of New Zealand ” Mr. Buchanan has 
wrongly referred Mr. Petrie’s plant to Pe See ogee 
a a Triodia.
