DESCRIPTION. 



CD VIII. E. eonciiina Maiden and Blakely, n.sp. 



Arbor parva gracilis, vel Mallee 6-12 pedes alta; foliis dilute viridibus, nitentissiniis, 5-11 cm. longis, 

 1-3 cm. latis ; infloresceutia in umbellis axillaribus 3-6 floris ; floribus pedicellatis ; operculo obtuso, striato, 

 calyce breviore; antheris versatilibus, loculis longitudinalibus ; fructu pedicellato, pyriformi vel clavato; 

 valvis subulatis, exsertis (8-10 x 6-10 mm.). 



A small slender tree or Mallee, 6-12 feet high. 



Juvenile leaves not seen. 



Mature leaves alternate, petiolate, narrow-lanceolate to falcate-lanceolate, more or less acuminate) 

 light glossy green, somewhat thick and with a very obscure venation, 5-11 cm. long, 1-3 cm. broad; 

 petioles slender, almost terete, 9-12 mm. long; lateral veins spreading at an angle of 40-45° to the midrib; 

 intra marginal vein very close to the margin, and sometimes blending into the marginal nerve. 



Inflorescence in axillary umbels of 3-6 pedicellate flowers, the peduncle compressed, broader 

 at the top, 7-10 mm. long. Buds clavate, more or less angular, on slender, slightly compressed pedicels, 

 ranging from 4-7 mm. long, sometimes two or more buds in the same cluster with longer pedicels than the 

 others. Calyx cupular, 5-6 mm. long, smooth or faintly bicostate, with very faint parallel veins. 

 Operculum blunt, depressed-hemispherical to cupola-shaped when inverted, striate. 3-4 mm. long, 6-7 mm* 

 in diameter, usually of a greater diameter than the calyx-tube. Filaments numerous, far more numerous 

 than in E. dumosa. Anthers moderately large, versatile, with broad cells and a large, oblong, dorsal gland. 

 Floral disc obscure or rudimentary. 



Fruit pedicellate, pyriform to mallet-shaped or somewhat turbinate, truncate, glossy, faintly and 

 irregularly costate, 8-10 x 6-10 mm. ; capsular disc obscure, valves subulate, lightly exserted. 



It appears to be a striking species with light green leaves and unique clavate 

 buds on long slender pedicels. It is depicted in Part IV, Plate 15, figs. 6a, 6b, under 

 E. incrassata (miscellaneous forms). 



RANGE. 



Camp 49, Victoria Desert, Western Australia, Elder Exploring Expedition, 

 12th September, 1891 (R. Helms). The type. This is the only locality known to us. 



AFFINITIES. 



1. With E. Griff ithsil Maiden. 



The buds of both species are somewhat alike in shape, but those of E . concinna 

 are more numerous in the head, much smaller, and less angular than the buds 

 of E. Grifliihsii. The fruits of the latter are also larger and more strongly costate than 

 those of E. concinna. 



2. With E. ochrophylla, n. sp. See p. 50. 



3. With E. dumosa A. Cunn. 



It has larger buds and different shaped fruits than the typical E. dumosa, and 

 light-green, glossy leaves,
