Following is the description : — 



Book. MS. ; Eoliis rhombeo-triangularibi ob u i iini igiu u itis coriaccis minute 



puncU'is (iiuiiitis |>a!l"lis) reticulata ve 



"This imarkable in the size and shape of its pel ■..-.•'■. The branches bi 



pated woody excrescences (galls), each with two or more, generally thn trp uany unequal, 



projecting wings, altogether exactly resembling tin- trail of fome Begonia." (Mitchell's !:■■::. .1 - ! 

 204, 1848.) 



Following refers to one of the above specimens : — 



" Xo. 336. June, 1846. Eucalyptus populifolius Hook. Ic. t. 87!), 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 10G. 



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



" /:'. populifolia Hook, from near Mount Owen, Mitchell, withou.1 Bow< rs or fruits, but with remark* 

 ably shaped galls on the branches, belongs more probably to E. ■platyphylla than to E. polyantkemos.'l 

 (B.Fl. iii, 210.) 



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. Decaisneana Blume. 



" 205. Eucalyptus Decaisneana Bl., ramulis corapresso-tctragonis ; foliis alternis lanceolatis faleatis 

 acuniinatissimis basi valde inaequalibus coriaceis glabris penninerviis ; pedunculis axillaribus cornpressis 

 pctiolum adaequantibus umbeilato 5-9 floris ; oporculo hernisphaerico mucronulato calycis tubo turbinato 

 triplo breviore. — E. dbliqua (hand Herit. !) Decaisnc in Nouv. Aim. Mus. d'hist. Nat. iii. p. 454 (excl. omnib. 

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



'' E. Decaisneana, according to Timor specimens kindly sent by Dr. Scheffer, the Director of the 

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

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

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



" Indeed also E. Decaisneana, if rightly recognised, may prove only a variety of 

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

 specimens of E. Decaisneana.
