ABROTANELLA PAPUANA, S. Moore, sp. nov. 
Herba pumila, scaposa, vix 2 cm. alta. Folia pauca, imbricata, linearia, obtusa, integra, 
ob margines involutos plus minus subteretia, petiolis latis vaginantibus piloso- 
ciliatis 5 mm. longis fulta, crassiusculo-coriacea, glabra, plerumque 12-15 mm. 
longa, 1 mm. lata. Scapus erectus, folis paullulum brevior, sparsim bracteatus, 
1-cephalus, circa 10 mm. altus. Capitula pansa 4x5 mm. Involucrum campanu- 
latum, 2-seriale, 3 mm. longum; phylla 12, inter se paullo inzequimagna, oblonga 
vel ovato-oblonga, dorso carinulata, crassiuscula, glabra, 1-1:25 mm. lata. 
Flosculi breviter exserti; exteriores circa 15, 9 , corollis tubulosis 4-fidis lobis tubo 
plane brevioribus 2 mm. longis, interiores perpauci (speciminis a nobis scrutati 2), 
5 , corollis 2-2:5 mm. longis, quam ex ceterorum paullo latioribus limboque brevi 
irregulariter 4-lobo  prseditis. Anthere incluse, oblongse, basi subevanide 
auriculate, 1 mm. longs. Styli rami truncati, 0'3 mm. longi. Achenia omnia 
verisimiliter fertilia, oblongo-ovoidea, compressa, apice rotundato-truncata, facie 
utravis costis 8 onusta omnino epapposa, adhue cruda 1:5 mm. longa, superne fere 
1 mm. lata. 
Camps XIII to XIV, 10,500 to 12,500 ft. 
Scape stoutish, bearing about two bracts like the foliage leaves, only smaller. 
From a distributional point of view, this is a plant of great interest. Exclusive of 
the species just described, the genus Abrotanella comprises 13 species, of which 7 are 
endemic in New Zealand and the neighbouring islands; the mountain summits of 
Tasmania and Victoria claim three more, while two are Fijian and one is a native of the 
Falkland Islands*. It will thus be seen that, Abrotanella being an Antarctic genus, 
the occurrence of a species so near the Equator as New Guinea is a fact of considerable 
importance. 5

ERECTHITES NOVOGUINEENSIS, S. Moore, Sp. nov. 
Herba verisimiliter perennis. Caulis ascendens, ramosus, foliosus, cito glaber. Folia | 
sat elongata, oblanceolata, acuminata, apice ipso obtusa, basin versus in petiolum 
brevem latumque gradatim extenuata, margine dentata, membranacea, glabra.

digesta. Bractee parvuke, filiformes, 1 mm. long, pedunculis propriis breviores. 
Involucrum anguste campanulatum, 6 mm. longum; phylla 8, anguste lineari- 
lanceolata, acuta, dorso carinulata, margine membranacea, phyllis additis interdum | 
paucis parvulis bracteis similibus calyculum efficientibus. Flosculi exteriores 8-10, 
?; horum corolla filiformis, stylo brevior, 5 mm. longa.  Flosculi interiores 2, 93
