370 Baron F. von Mueller on Dysoxylon Schiffneri. 



downy; stigma depressed-hemispherical; ovary four-celled, 

 with two superposed ovules in each cell ; fruit globular, 

 glabrescent, brown outside ; pericarp rather tliin, not 

 unless very tardily valvular ; seeds witiiout any arillus. 



In the Mount Bellenden-Ker Ilanges ; Karsten. 



A tree attaining a height of 80 feet. Bark greyish- 

 brown, smooth. Wood yellowish. Leaflets on very short 

 stalklets, in few pairs, so far as the very scanty material 

 admits of judging, 2-5 inches long, somewhat inequilateral, 

 very minutely dotted. Eacemes two or more together, 

 2-4 inches long, fragrant. Petals nearly half an inch 

 long, pure white, upwards slightly imbricated, downwards 

 valvular. Fruit not seen quite ripe, then not fully an inch 

 long, nor showing any indication of valvular structure, 

 four-celled. Seeds ripening solitary in each cell, turgid, 

 almost longitudinally aduate ; testa thin, dark-brown, 

 loose. Albumen none. Cotyledons planoconvex, collateral. 

 Radicle very short, terminal, almost concealed between the 

 minute lobes of the cotyledons. 



I have left this remarkable Meliaceous tree in the genus 

 Dysoxylon, as constituted at present, although the structure 

 of the calyx is so exceptional in the genus, that under the 

 sectional name here adopted, or perhaps under that of 

 Epicharis^ this species with its nearest allies might be 

 raised to generic distinction, especially as the fruit does 

 not seem to slit into any valvular divisions, in which 

 anomaly, however, D. Klanderi coincides (vide Fragm. 

 Phytogr. Austr., ix. 134), thus showing an approach to 

 Sandoricum. The genus Dysoxylon, by admitting into it 

 Hartigshea with arillate seeds, and Didymocheton with 

 sepals overlapping at their margins, has become too 

 artificial, while in Hartigshea spectahilis the anthers are 

 inserted below the merely crenulated summit of the 

 staminal tube, a characteristic on which otherwise much 

 stress has been laid by Casimir de Candolle. The remark- 

 able location of the inflorescence is not without example in 

 the genus, it bursting also in several other species away 

 from the leaves out of the stem or main branches. 



This new species is nearest allied to D. caidostachyum 

 from New Guinea, with which and the other species 

 placed by Miquel in the section Epicharis it accords in the
