DESCRIPTION. 



LXXXVII. E. Pimpiniana, sp. nov. 



Frutex 3-5 altus, " Mallee " vocafca. Folia matura pallida, eoncoloria, priecrassa, lanceolata, ovato- 

 lanceolata, ovata vel elliptica. Vena peripherica margini incrassa'a contigua vel congruens. Vena^ non 

 prominulse. Folia circiter, 7-5 cm. x 2-5 cm., petiolus 2 cm. longu.s. Fructus pyiifo rmes vel sub-cylindiici, 

 aliquando orificio lenissime constrieti, aliquando lenis-iime distensi juxta oiificinui, ciroiter 1'5 cm. loiigi et 

 1 cm. lati. 



Mature leaves pale coloured, dull on both sides, petiolate, very thick, lanceolate to ovatedanceolate, 

 ovate or elliptical, intramarginal vein identical with the slightly thickened margin, or but slightly 

 removed from the edge. Venation, other than the midrib, inconspicuous, lateral veins feather like, at about 

 an angle of 45° with the midrib. Oil dots minute, and numerous, resembling black spots under the lens. 



Average dimensions of the leaves, 7"5 by 2'5 cm. ; and the length of petiole, 2 cm. 



Anther broad, the openings wide, and with a large gland at the back. 



Fruits pear-shaped to sub-cylindrical, sometimes slightly constricted at the orifice, and sometimes 

 slightly distended one-third of the distance from the mouth ; about \-5 cm. long by 1 cm. broad. Three 

 or four celled, the points of the valves deeply sunk below the orifice, rim well marked though not broad. 



Several in an umbel, the rounded pedicel, which only slightly tapers from the fruit, varying in 

 length from one-half to the whole length of the fruit. 



The fruits pendulous and the common peduncle rounded (hardly flattened and never approaching 

 strap-shape) exceedingly long (commonly 4 cm.). 



The proposed specific name is from the native name of the plant. 



The material of this species is so scanty that for a long time I hesitated to 

 describe it as new. But it seems sufficiently distinct from what appears to be its 

 nearest congener that I think it is in the interests of science to give it a separate 

 name. 



I do not like describing a species on such imperfect material, but I bear in 

 mind Bentham's justifiable example with U. ccesia, and a description with a 

 figure will, sooner or later, lead to the collection of a full suite of specimens. 



The material consists of mature leaves, a ripe fruit (no seeds), together with 

 a number of more or less ripe fruits in situ, and a few anthers. There are the 

 remains of a number of anthers, l)ut insects had destroyed most of them. 



RANGE. 



Only known from one locality at present. It was collected by Mr. Henry 

 Deane, M.A., M. Inst. C.E., Consulting Engineer to the Commonwealth, while 

 inspecting the trial survey of the Transcontinental Railway between Port Augusta, 

 South Australia, and Kalgoorlie, Western Australia, in June, 1909. 



Mr. Deane's notes are " Dwarf Mallee, 3 to 6 foot only. ' Pimpin ' (native 

 name), Sand-hills east of Ooldea, South Australia " {i.e., north of Fowler's Bay).
