Flowers. — Buds with short, slightly flattened peduncles, the individual flowers sessile or almost 

 so, four to seven in the head as seen. Opercula hemispherical, about half the length of the calyx-tube, 

 which tapers only slightly, and which is usually sub-angular. (Filaments turn red on drying. Anthers 

 open in parallel slits, attachment of filaments versatile, large gland at back.) 



Fruits not seen. 



[Fruits conoid to hemispherical, small (rather more than 5 mm. in diameter), nearly sessile, the 

 short broad pedicel continued into the calyx-tube, formiiig two or niore angles. Peduncle of 5 to 7 mm., 

 also flattish and angular. The fruit with a narrow rim, the tips of the capsule slightly exsert and not 

 adnate to the edge. Description drawn up from material collected by Mr. J. H. Niemann at Pine Creek, 

 Northern Territory, and given by me in Journ. Roy. Soc. N.S.W. li, 450, 1917.]

In the following year (viz., 1916) Mr. Fitzgerald, on the eve of his departure 

 for the war, placed certain of his botanical manuscripts in my care, and I found the 

 following description of this species amongst them, which supplements, to some extent, 

 my original description : — 



Arborescent, branchlets angular; leaves on the young plants opposite or sub-opposite, shortly 

 petiolate, ovate-cordate, obtuse, those on the tree alternate, conspicuously petiolate, broad to narrow- 

 lanceolate, usually falcate, acuminate, all thin, of dull lustre, the oil dots copious, veins fine, numerous, 

 ascending and evident, reticulated between, intramarginal one adjacent to the edge; flowers 4-8, sessile 

 and rather closely packed, on axillary and lateral thick terete peduncles which are much dilated upwards ; 

 calyx-tube obconical, not ribbed.; lid depressed, hemispherical, much shorter than the calyx-tube; 

 stamens inflected in the bud ; anthers oblong, with parallel distinct cells dehiscing longitudinally ; ovary 

 flat topped; style short. 



Leaves (Juvenile) 3-4 inches long, (Mature) 6-8 inches long, the petioles to 1 inch. Peduncles 

 2 lines long; calyx-tube 2 lines or less in length. Stamens 2 lines, the filaments white. 



Fruit not seen. 



Locality. — On grassy plains. Upper Isdell Eiver, base of Artesian Range (W.V.F.). The species 

 is named in honour of Dr. F. M. House of Western Australia. 



Afiinity. — E. foscunda, Schauer. 



RANGE. 



• It is a tropical species occiuring both in Western Australia and the Northern 

 Territory. 



Western Australia. — The type comes from Mount Barnett Homestead, Kimberleys, 

 North West Australia, (W. V. Fitzgerald, No. 1,014)— " In swampy and wet sandy 

 localities, associated with the coarser kind of grasses were E. Houseana and 

 E. ptychocarpa." (Fitzgerald in " Kimberley Report," p, 12).
