HIGHLAND PLANTS FROM NEW GUINEA. 37 
Uncinia Hookeru ; Boott in J. Hooker, flora Antarctica I, 91, pl. II (1844). 
Mount Knutsford. 
The only specimen obtained has still narrower leaves than those of the plant, 
illustrated in the work above quoted, and the spike is scarcely one inch long; but 
these differences would represent merely a small state, and there are no other 
discrepancies observable. 
Agrostis montana ; R. Brown, prodromus flores Novee Hollandiew 171 (1810). 
Highest region of the Owen Stanley’s Ranges. 
The spikelets are rather larger than in the generality of Australian specimens. 
The relation of this grass to A. Magellanica and A. setifolia has to be yet further 
studied. Steudel’s description of the first mentioned agrees fairly well with our 
plant, in which the accessory rhacheole is not always developed. Mr. John Buchanan 
in his work on the ‘Indigenous Grasses of New ZGealand’’ offered some very 
appropriate remarks about the undesirability of removing the species of the section 
Deyeuxia as a genus from Agrostis. 
Azra caespitosa; Linné, species plantarum 64 (1753). 
Mount Knutsford, at and close to the summit. 
The leaves are there much oftener compressed-filiform and slightly channelled 
only, than flat, but otherwise the characteristics are not those of A. flexuosa. The 
spikelets attain there fully one-third of an inch in length; terminal membrane of the 
clasping-cylindric petioles is usually much pointed. Small forms of this grass 
resemble Catabrosa antarctica. 
Danthoma penicillata; F. v. M. Fragmenta phytographie Australie VIII, 135 (1878). 
At the highest elevations of the Owen Stanley’s Ranges. 
There from one-half to one and a-half feet high. The bulk of the obtained 
specimens belongs to that form, which comprises D. semiannularis, D. Unarede and 
D. gracilis, but some of the individual plants seem to pass gradually into D. bromoides 
and D. flavescens. 
The separation of the hairlets into tufts on the bracts, supporting the flowers, is 
more or less marked, and the twisting of the main-awn is also one of degree. The 
collective name, here again adopted for the species, is adduced already by Palisot de 
Buauvois (Hissai d’une nouvelle Agrostographie 29) from the Arundo penicillata of 
Labillardiére as a distinct designation, but limited only to one form, just as Roemer 
and Schultes comprehended merely some varieties of the polymorphous Agrostis 
Solandri under the specific name A. Forsteri. Passingly the appellation D. penicillata 
(in the wide sense) was used in the “‘ Vegetation of the Chatham-Islands” at p. 60 as 
early as 1864.
