A. versicolor differs in foliage, calyx and corolla. Neither can it, 

 although in large measure homoplastic with, be referred to 



B. vestita Engl., B. Garckeana K. Schum., nor B. potamoxenos 

 K. Schum., all of which, according to Lindau, have honeycombed 

 pollen, and are thus true Ruellias, as is B. aruensis S. Moore from 

 the Aru Islands. The fact is that in New Guinea and the neigh- 

 bouring islands we have a series of homoplasts differing chiefly as 

 to whether their pollen is honeycombed {Buellia), or spiny or at 

 least tuberculate {Aporaellia). 



Aristolochiace^. 



Aristolochia pithecurus Eidl., sp. nov. Frutex scandens, 

 elatus, caule 1"5 cm. crasso, cortice rugoso, ramis pubescentibus. 

 Folia juvenia undique pubescentia, adulta coriacea, superne levia, 

 glabra, subtus prassertim in nervis hirta, oblonga, cuspidata, basi 

 cordata, 12 cm. longa, 6 cm. lata, nervis 3-paribus, subtus dis- 

 tinctis, reticulatis, petiolis tortis, 1 cm. longis, pubescentibus. 

 Flores sessiles. Bracteae tubulosse, dilatatse, latae, 1 cm. longae, 

 hirtae. Corolla tubaeformis, 3-5 cm. longa, extus hirta, pallide 

 viridis, purpureo-reticulata, basi dilatato 1 cm. longo, hinc angus- 

 tato, superne dilatato, limbo 1*4 cm. lato, lobis tribus, rotundatis,

" A considerable climber. Flowers with ground colour pale 

 green covered with a network of purple lines." 



This curious plant is allied to A. Balansce Franch. of Cambodia, 

 differing in its cordate leaves. 



The corolla has three rounded short lobes, and one slender, 



filiform one slightly dilated towards the tip and resembling a 



monkey's tail.

PETER EWING. 

 (1849-1913.) 



Many field botanists, both in Scotland and England, must, 

 like myself, have felt keen personal regret when they heard in the 

 autumn of last year of the death on August 3, at Glasgow, of 

 Peter Ewing. For nearly half a century he had devoted all his 

 spare time to the study of the flora of his native land, and the 

 knowledge which he had thus acquired he was always ready to 

 impart to others. 



Peter Ewing was a native of Kinross, where he was born in 

 1849. His father was a stationer in a small way, and to this 

 business he afterwards added that of photographer. His children, 

 of whom there were six sons and two daughters, had to learn at 

 an early age that work is the lot of man. Peter, the second son,
