GIBBSIA INSIGNIS Rendle, sp. nov. 
Frutex ramulis foliiferis colore cinerascente et pilis brevibus appressis hispidis. 
Folia breviter petiolata, lanceolata, acuminata, margine crenato-dentato recurvato, 
in facie superiore eleganter reticulato-impressa, hispidula, subtus inter nervos rubros 
conspicuos dense albo-tomentosa; petiolus ut in ramulo hispidus. Stipwle infra 
medium bifide, triangulari-acute, in margine superiore ciliolate, uninervie. n- 
florescentie@ geminatx, sepius bis vel ter dichotome, pedunculo ramisque tenuibus, 
foliis 4-2-plo breviores. Cymule sepe floribus evolutis 7. Anthere connectivo 
umbonato ; filamenta perianthium equantia. Exocarpiwm lete-brunneum. 
Leafy branchlets 2-2-5 mm. thick. Leaves 5-8 cm. long, 1:2-1'7 cm. 
wide ; petiole 3-7 mm. long. The leaves have a striking appearance ; the 
three main nerves are impressed on the upper face, which is beautifully 
embossed with small chequer-like areas representing the transverse and 
small connecting veins; the red main nerves on the lower face stand out 
conspicuously on the intensely white tomentum covering the rest of the 
surface. Stipules 3°5 mm. long, united in the lower third, each with a 
strong median nerve. Inflorescences generally in pairs in the leaf-axils, to 
2-5 em. long ; the small dense cymes are crowded at the ends of the short 
ultimate branches, the number of flowers in each varies—a typical one 
is represented in fig. C, of which a diagrammatic analysis is given in fig. D. 
Bracts about *5 mm. long. Flowers jointed on very short pedicels, which 
are less than 1 mm.long. Bud of male flower 1:5 mm. in diameter, perianth- 
segments 1:6-1:7 mm. long. Ovary slightly compressed, ovoid, with a 
narrow rounded keel running along the back and bearing a row of short 
forwardly-pointing sete, at the base of each of which is a black dot; 
similar but slightly larger sete surround the stigmatic disc, covering it 
when young but ultimately becoming reflexed (figs. I, J). Fruit about 
1 mm. long; crowned with the withered stigmatic disc ; exocarp bright 
chestnut-brown. :

A second species of this genus was collected by Mr. Kloss on Dr. 
Wollaston’s Dutch New Guinea Expedition. The material is scanty, but 
there is no doubt that it represents a plant congeneric with the Arfak 
specimen and a distinct species. A description is appended :— 
GIBBSIA CARSTENSZENSIS Rendle, sp. nov.

elliptica, acuminata, margine crenato-dentato, -recurvato, in facie superiore reti- 
culato-impressa, hispidula, subtus nervis exceptis albido-tomentosa; petiolo tenui, 
hispido. Stcpule supra medium bifid, acute. Inflorescentia et fructus velut in 
G. insignis. 
Leaves 4°5-7 cm. long, 2-2'5 cm. wide ; petiole 1-2°5 em. long; bracts
