HIGHLAND PLANTS FROM NEW GUINEA. 11 
Vittadimia Alinae. 
Rhizome ramified, descending or somewhat procurrent; stems short, rather 
hard; leaves quite small, crowded on short somewhat clasping petioles, beset as well 
as the branches and most other parts of the plant with jointed spreading hairlets, 
cuneate or verging into a lanceolar or rhomboid form, flat at the margin, often deeply 
and acutely denticulated at and towards the upper end; headlets of flowers small, 
singly terminating slender conspicuous peduncles or occasionally almost sessile ; 
involucral bracts in about three irregular rows, narrow-lanceolar, somewhat pointed, 
slightly scarious at the margin, the outer often more than half as long as the inner ; 
peripheric flowers nearly biseriate, their licular expansions linear-lanceolar, about as 
long as the tube; stigmas of the central flowers extremely narrow, pointed, 
subtle-barbellate ; achenes when well developed moderately compressed, bearing 
minute appressed hairlets; pappus-bristlets in two rows, ciliolar-rough, the outer 
mostly half as long ag the inner. 
On Mount Victoria, among Styphelias. Gladly named by desire of the discoverer 
in honour of one of his young daughters. 
Some individual plants, even when full in flower, only two inches high, others 
reaching six inches in height. ; 
I have left this plant reluctantly out of the genus Aster, into which I had first 
placed it, and to which it approaches fairly well in its involucre and pappus; the 
augmented number of liculate flowers bring it rather to Hrigeron, it being indeed not 
very distinct in some respects from our southern Erigeron pappochromus; but the 
finely pointed stigmas of the bisexual flowers are particularly those of Vittadinia, of 
which it has also more the aspect, so that it may be best to keep the plant in that 
genus. 
The late Dr. Wilhelm Hillebrand offered some very apt remarks on Vittadinia and 
Tetramolopium as regards their generic limits in his Flora of the Hawaian Islands, p. 
197 (1888). Perhaps it would be advisable, to reduce Vittadinia to Hrigeron 
altogether, its peculiar stigmas occurring also in the Oritropium of that genus. 
Vittadinia macra. 
Stems generally several, erect or recumbent towards the base, branchless or 
variously branched ; leaves very small or minute, crowded, mostly appressed, as well 
as the peduncles and bracts bearing an imperfect lanuginous indument, from broad- 
linear to narrow-elliptic, with broad clasping base sessile, somewhat concave, blunt, 
entire ; headlets of flowers small, singly terminal, on short peduncles or almost sessile ; 
involucral bracts in about three irregular rows, broad-linear, bluntish or hardly pointed, 
the outer often more than haif as long as the inner, all without conspicuously scarious
