2*5-3 cm. long, bearing small capitula, over 5 mm. across, of 6-7 flowers, 

 each flower subtended by a small caducous, concave, pubescent bract l - 5mm. 

 long. Calyx-lobes 2 by 1 mm., ovate acute, adnate to the ovary. Longest 

 stamens with anthers 3 mm. long. Style "2'5 mm. long, subulate with 

 minute punctiform stigma. Ovary 1*2 mm. long, pubescent, adnate to the 

 axis. 



This plant is very near Callicoma Stutzeri F. Muell., first distributed by 

 him as Stutzeria callicomoides, then reduced to Callicoma, as, in the absence 

 of fruit, he considered the generic position dubious. It undoubtedly belongs 

 to Pullea, the only descrepancy being in the position of the ovules, which 

 are figured for Pullea (Engl. Bot. Jahrb. lii. (1914) 165, fig. 9) as lateral ; 

 whereas in both the above plants they are inserted as described by 

 von Mueller for P. Stutzeri, which is distinguished from Callicoma by the 

 glands erroneously called petals by him, but correctly described as glands 

 by Bailey ('Queensland Flora,' pt. ii. 536), which occur opposite the inner 

 whorl of stamens, and the more or less inferior to semisuperior ovary. The 

 Arfak plant is distinct from the above in the obscurely dentate, obtuse, more 

 reticulate leaves, the more compound, less densely capitate inflorescence, 

 smaller flowers, greater number of glands, and the inferior ovary.

The leaves of this species are very distinct, the largest being 5 cm. by 

 over 3*5 cm., with veins so impressed on the upper surface that they limit 

 raised lateral reticulate areas, which make the leaves very concave and 

 bullate in appearance, the convex under surface being lighter in colour 

 and tomentose. The young leaves are densely pubescent on both surfaces. 

 Petioles 8 mm. long, pilose. Panicles 8-13 cm. by 4'3-4'5 cm., composed 

 of ternately verticillate cymes, with bracts simulating foliage-leaves greatly 

 reduced in size. Flowers 2 mm. long, sometimes 5-lobed, pilose with 

 scattered dark glandular hairs, as are also the pedicels, which are 2 mm. long,
