The panicles are simple in />'. popidneo-acerifoUus, mach 

 branched in B. acerifolius. 



The riower-buds of />'. poptdneo-acerifolius are, when unex- 

 panded, long-pointed, tiowers 4-6 lobed, the lobes recurved. Jn 

 /). acerifolius, the shape of the buds is more turbinate and, when 

 unexpanded, nearly Hat-topped, giving the bud the aspect of a 

 peai*, but, in rare cases, the bud is somewhat pointed. 



The flowers appear to be much more numerous than in 7>. 

 Sicerfolius. "The colour of the calyces holds the middle between 

 that of the respective organ of the parent-plants; it is pale 

 yellowish outside, much as in B. populnemn, but inside crimson 

 and not sprinkled as in B. acerifolium " (Original descrip- 

 tion). This requires some correction. The flower of B. popul- 

 neo-aceri/olius is usually self rose-pink and not pale yellowish, 

 although some flowers may be a little pale yellowish outside; but 

 inside, sprinkled rose-pink, giving the general impression of 

 greyish-rose, except at the base of the throat where it is greenish- 

 vellow. The outside is Salmon Old Rose No. 143, shade 1, and 

 inside Madder Carmine, No.241, shade 4, of Rep. de Couleurs, to 

 speak with precision. 



The flower of B. acerifolius is not "sprinkled"; it is quite a 

 self scarlet. It is No.85 (shades 1 and 2) or scarlet, of Rep. de 

 Couleurs. 



(2). The tree which many knew as the Garden Palace one, is 

 strictly typical B. popiilneo-acerij'oliiis; it was removed in con- 

 sequence of the widening of Macquarie Street to Bed No. 9, 

 Middle Garden, in 1912, where it is now about 18 ft. high, 2 ft. 

 in girth 3 ft. from the ground, and it flowers every year, usually 

 in November-December, but sometimes January. Its origin is 

 unknown. 



(3). There are some typical trees of B. populneo-aceri/olius in 

 o-ardens at Parramatta. of considerable age. I first receiveu 

 specimens from JVlr. Fred. Williams. 



(4). Mr. J. A. T. Kochfort, Inspector of Stock, Jerilderie, .sent 

 me some specimens from a tree growing at the Public School, 

 which are quite typical of B. popiiliieo-acerifolius. Mr. llochfort 

 sent pods, which are rather larger than those of JJ. populneus, 

 and smaller than the pods of B. acerifolius.
