New Victorian Haloragis and Genus Pluchea. 133 



fruit-bearing specimens having been obtained. Fruit 

 roundish -ovate in outline, from hardly one-quarter to fully 

 one-third inch long, the four surrounding membranes two 

 and two confluent with the broadest lobes of the calyx, and 

 decurrent much beyond the fruit-cells, the latter small in 

 proportion to the pericarp. Matured seeds not available 

 yet. 



This species shows most affinity to H. racemosa, from the 

 mild coast-region and low hills of South-western Australia, 

 the only other congener (unless H. alata and H. monosperma), 

 which attains to great height ; but the leaves are generally 

 shorter, their denticles rather curved inward than spreading 

 and soon getting blunt ; the floral leaves often at least do 

 not become much diminished in size ; the fruit is pro- 

 portionately broader, its longtitudinal membranes are more 

 expanded and not almost equally distant, while its endocarp 

 is harder. Whether the petals are gradually much acuminated 

 and generally longer than the stamens, as those of H. race- 

 mosa, remains j^et to be ascertained. The last-mentioned 

 species should also be placed into the section of oppositi 

 florse. Mr. W. Webb found it on Mount Lindsay (Mj.*s. 

 M'Hard) near the Blackwood River. In various respects 

 our new sub-alpine plant is allied also to H. scordioides, 

 H. alata and H. Gossei. Now an apt opportunity is afforded 

 to point out, that the genuine H. alata from New Zealand 

 and the Chatham Islands cannot be regarded as absolutely 

 identical with the East Australian plant, admitted under 

 that name into the Flora Australiensis, in as much as the 

 small blunt and often downward-bent appendages at the 

 angles of the fruit in the legitimate species do not occur in 

 any of the Australian specimens seen by the writer of these 

 remarks; besides, the leaves of our plant are longer and 

 narrower, also more decurrent into the stalk, while the floral 

 leaves are more reduced to bracts ; indeed the Australian 

 plant verges closely to H. serra, but has four styles, as also 

 a four-celled and four-seeded fruit ; either as a variety or 

 as a distinct specific form it might be distinguished under 

 the name exalata. 



H. cordigera has been traced to the Serpentine River 

 (F. V. M.) ; the fruit is shorter than the calyx-lobes, and not 

 rarely bearing hairlets. 



H. scoparia bears a fruit roundish-ovate, compressed, 

 beyond the base upwards slightly quadrangular, much 

 longer than the calyx-lobes, two-celled and two-seeded.
