Following is the description : — 



Hook. MS. ; foliis rhombeo-triangularibis obtusissirnis longius petiolatis coriaceis minute 

 punctatis (punctis pallidis) reticulato-vcnosis. 



'" This species is remarkable in t-lie size, and shape of its petiolated leaves. The branches bear turbi- 

 nated woody excrescences (galls), each with two or more, generally three, sharp angles, and as many unequal, 

 projecting wings, altogether exactly resembling the fruit of some Begonia." (Mitchell's Trop. Austral. 

 204, 1848.) 



Following refers to one of the above specimens : — 



" No. 336. June, 1846. Eucalyptus populifolius Hook. Ic. t. 879, and galls. 

 Sub-tropical New Holland. Lieut.-Col. Sir T. L. Mitchell." (Copy of a label in Herb. 

 Cant, ex herb. Lindl.) Figured at figs, 2a and 2b, Plate 106. 



Doubtless similar to the Mount Owen specimen referred to by Bentham below. 



' : E. populifolia Hook, from near Mount Owen, Mitchell, without flowers or fruits, but with remark- 

 ably shaped galls on the branches, belongs more probably to E. plalyphylla than to E. pohjanthemos.'* 

 {B.Fl iii, 243.) 



For a reference to Mt. Owen, see Mitchell's " Tropical Australia," p. 204. 



Mr. Froggatt informs me that these winged galls (fig. 2a) are the female galls 

 of Brachyscelis munita Schrader, and that the dots on the leaves (fig. 2b) are made by 

 parasitic hymenoptera (Chalcidese). 



I have referred to the confusion which has arisen through Hooker having named 

 two distinct trees E. populifolius under E. populifolia Hook., (as now accepted), at Part X 

 page 342 of this work. See also (under E. populnea F.v.M.) at page 340. 



Still another E, populifolia, viz,, E. populifolia Desf., I shall refer to under 

 E. tereticornis Sm. 



4. E. Deeaisneana Blume. 



'"205. Eucalyptus Deeaisneana BL, ramulis compresso-tctragonis ; foliis alternis lanceolatis falcatis 

 acuminatissimis basi valde inaequalibus coriaceis glabris penninerviis; pedunculis axillaribus compressi3 

 petiolum adaequantibus umbellato 5-9 floris ; operculo hemisphaerico mucronulato calycis tubo turbinate 

 triplo breviore. — E. obliqua (baud Herit. !) Decaisne in Nouv. Ann. Mus. d'hist. Nat. iii, p. 454 (cxcl. omnib. 

 Syn.). In Timor.'' (Blume in Mus. Bot. Lugd-Bat., Vol. 1, p. 83, 1849.) 



" E. Deeaisneana, according to Timor specimens kindly sent by Dr. Scheffer, the Director of the 

 Botanic Gardens, Java, belongs to the series Normales, not to Benantherae ; its leaves are more or less 

 conspicuously inaequilateral, the margin of the calyx-tube is somewhat protruding beyond the vertex of 

 the capsule at least in a young state."' (Mueller, Papuan Plants, i, 9 [1875]). 



: ' Indeed also E. Deeaisneana, if rightly recognised, may prove only a variety of 

 E. alba." (Mueller in Eiicalyptographia under E. alba.) I have not seen authentic 

 specimens of E. Deeaisneana.
