160 ON STERCILIA (BRACHYCHITON) LURIUA AND DISCOLOR, 



into S. discolor or bear leaves of both forms, while young trees, 

 raised from seeds of these trees, preserve completely the character 

 of S. luri'ln. From the above we can only draw the conclusion 

 that S. lurida is only the young* state of aS. discolor, and cannot 

 even rank as a distinct variety, much less as a species. 



Observations have been made only on cultivated plants; we 

 invite observations made on plants in their natural habitats. We 

 propound the following question : — 



Have you7ig plants of .s'. discolor ever been noticed with the 

 foliage characteristic of this species (leaves angled or shortly 

 lobed and white underneath) 1 



The two plants grow in the same situations; they were first 

 collected together (by Moore) and described together (by Mueller, 

 Fragm., i. i. 1858). 



B. discolor : foliis subcoriaceis, breviter 5- 7 lobis, supra glabris, 

 subtus tenuiter cinerascenti-velutinis. See also Bot. Mag. t. 6608. 



B. laridum : foliis profunde quinquefidis herbaceis fere con- 

 coloribus parce pubescentibus. See also Fragm. ii. 177. 



We are keeping the other species of Stercrdia under ol)servation. 



Following is Prof. Terracino's suggested arrangement compared 

 with those by Mueller and Bentham : — 



A. Terracing. F. v. M.'s Census. 



Benth. Fl. Austr. 



(as iSterculia.) 



B. paradoxus, Sch. & Endl. 



a. typicus B. paradoxus, Schott. S. ramijiora, Benth. 



/3. Buhvilli B. BidiviUi, Hook. S. Bidwidi, Hook. 



V. discolor B. discolor, F.v.M. S. discolor, F.v.M. 



S. luridus B. luridus, C. Moore S. lurida, F.v.M. 



B. acerifolius, F.v.M. 



Q. typicus B. acerifolius, F.v.M. <S'. acerifolio, Cunn. 



f3. Gregorii B. Gregorii, F.v.M. S. diversifolia,G. Don, 



var. 1 occideyitalis. 



* Perhaps for this reason we must retain the name discolor for the double 

 plant.
