DESCRIPTION. 



XXX. E. Luehmaniiiana, F.v.M, 



Fragm. xi, 38 (Fasciculus Lxxxix, Nov., 1878). This is in Latin. It may be 



redescribed in the following words: — ■ 



A straggling, tall shrub or small tree, rarely exceeding a height of 15 to 20 feet, or a stem-diameter 

 of 3 inches. The stem smooth, and the timber pale-coloured. 



This species is glaucous, even nearly white. At the same time it imperceptibly passes into a non- 

 glaucous form. The branchlets are angular, and the species is coarse, — peduncles, fruits, leaves, &c, 

 being alike large. 



Juvenile leaves, — Coarse, up to 7 inches long by i inches wide. The resemblance to those of 

 E. Jicemastoma is striking. 



jlature leaves. — Distinctly falcate, up to 8 inches by 1-J- inches. Coriaceous ; edges thickened ; 

 marginal vein usually at a little distance from the edge. 



Peduncles. — Very much flattened. I have specimens which spread out upwards, so much that 

 they are J inch wide at the place of attaclmient of the inflorescence. Top of peduncle quite broad and 

 fleshy, in which the pedicels are articulate. 



Buds. — Angular, pointed. 



Calyx-tube. — The calyx often tapers into a widely expanded lobe, which is articulate on a broad- 

 topped common peduncle; usually seven flowers in a head. 



Operculum. — Double operculum or large calyptra-like bracts enveloping the whole head of flower- 

 buds, and only thrown off when the individual flower-buds are nearly ready to throw off their own opercula. 



Fruit. — Often pale brownish and glossy. 5-celled, corrugated — partly due to drying ; the rim 

 slightly projecting. 



Notes supplementary to the description. 



Specimens from the north of Port Jackson (between this estuary and the 

 Hawkesbury River) appear to differ from the type only in the following particulars: — 



(1) They are glabrous. 



(2) The calyx-tube is more elongated, and the stalk of the fruit thinner. 



The most obvious difference is the almost entire absence of glaucousness : no 

 other difference is obvious or constant. 



Plants from the Spit (Middle Harbour, Sydney) have the buds quite pointed, 

 and long, with non-glaucous leaves. This is a form which would be separated from 

 E. virgata with greater or less reluctance, according to the elasticity of view held in 

 regard to the definition of that species.
