50 R. H. CAMBAGE. 



Mr. J. H. Maiden informs me that lie received an incom- 

 plete specimen of this species from Ohillagoe in 1911. 



The species blooms in March, and I am indebted to Miss 

 Ethel L. Maitland for flowers. 



Reversion ("sucker") foliage — Ovate-lanceolate, 3-7 cm. 

 long, 5 mm. to 2 cm. broad, so far as seen. 



Seedlings — Hypocotyl terete, red, 3 mm. to 1 cm. long, 

 1 mm. thick at base, glabrous. 



Cotyledons obtusely quadrilateral to reniform, entire, 

 2*5 — 3 mm. long, 4-7 mm. broad, upperside green, under- 

 side red; petiole 3 mm. long. 



Stem brownish-red in lower portion, brownish-green in 

 upper part. 



Seedling foliage opposite for about two or three pairs, 

 entire, glabrous, linear; petiole 2 — 4 mm. First pair 1'6 — 

 2*4 cm. long, 1-2 mm. broad, upperside green, underside 

 purple; leaves Nos. five to ten up to 5 cm. long, 2-3 mm. 

 broad. 



A seedling about one foot high has an opposite pair of 

 nodules or swellings 1 about the axils of the cotyledons or 

 the first pair of leaves. 



The species is named in honour of Sir William Portus 

 Oullen, k.c.m.g., m.a., ll.d., Chief Justice of New South 

 Wales and Chancellor of the University of Sydney, who has 

 done much to encourage the preservation of our native flora. 



Affinities. 

 Its closest affinity appears to be with E. crebra F.v.M., 

 which it resembles in bark, timber and mature leaves, but 

 differs in the shape of buds and fruits, and in the seedling 

 foliage. It also resembles E. paniculata Sm. in its bark, 

 but differs in the timber and other characters.
