 DRIMYS (TASMANNIA) ARFAKENSIS Gibbs, sp. nov. 



Arbor parva, utrinque glaberrima, dioica ; rami et ramuli bene foliati ; 

 cortex fere nigrescente, striati. Folia leviter obovato-lanceolata, basi sensim in 

 petiolum subalatum satis longum angustata, apice acutiuscula, margine revoluta, 

 Integra, coriacea, supra nitentia, utrinque reticulosa-venosa. Flores parvi, graci- 

 liter pedicellati e basi innovationum fasciculatiin oriundi. Flos d sepala 2, 

 petaloidea. Petala 12-14, ligulata. Ovaria 2-4. Stigma carnosum, cristatum, 

 apiee introrsum decurrens. Ovula 15. 



Hal). Arfak Mts., on S.W. ridge, running up to Angi lakes, 7000-8000'. 

 Fl., $ ? . Dec. 5533. 



This tree, with symmetrical dense crown of dark leaves and pendent 

 white flowers, turning pink later, was abundant in the forest and in a 

 few open spaces along the crest of the ridge. Largest leaves + 5'5-6 cm. 

 by 2*3 cm., the midrib conspicuous, with lateral veins anastomosing on the 

 margin of the leaf. Petiole dark-coloured, 5 mm. long. Pedicels slender, 

 + 1-2 cm. long. Sepals 6 mm. by 2 mm. Petals unequal, up to 6 mm. long 

 and not 1 mm. broad. (The specimens show only expanded flowers : what 

 I have described as a sepal is still in position on one of the flowers, and as 

 there is apparently a scar opposite, it points to there being two members, 

 very caducous, in the outside whorl of the perianth.) Ovaries 4 mm. long. 

 Leaves, sepals, and ovaries are densely gland-dotted, but neither cortex nor 

 leaves are pungent to the taste and only very slightly aromatic. This plunt 

 is nearest to D. piperita Hook, f., of N. Borneo, Philippines, and S.W. New 

 Guinea. It differs in habit, in the shape and texture of the leaves, aud the 

 much smaller flowers with more numerous and narrower petals.
