Umbelliferae. 



Hydrocotyle plebeia, R. Br. Beachport. Creeping among 

 other plants in sheltered spots. Resembles H. pterocarpa, 

 F. v. M., but the fruit, although not quite ripe, has no sign of 

 wings, and is 1J-2 mm. broad ; plant glabrous, except for a 

 small tuft of hairs at the base of the leaf, which is also some- 

 times found in H. pterocarpa; petals purple, spreading. A 

 Western Australian species, not hitherto recorded for South 

 Australia. Bentham suggests that H. pterocarpa may prove 

 to be a variety of H. plebeia. 



*Pastinaca sativa, L. "Parsnip." Growing wild along the 

 railway reserve, Millicent, to a height of 1^ m. Recorded by 

 Bentham as growing near Adelaide, but I have not previously 

 seen it wild. 



*Conium maculatum., L. "Hemlock." This handsome but 

 poisonous weed is becoming common in fields and vacant lots 

 near Mount Gambier and Millicent. 



Epacridaceae. 



Acrotriche ovalifolia, R. Br. Beachport. Fruit 3-4-celled. 

 A. serrulata, R. Br. Beachport (Dist. G). An almost glabrous 

 plant, the leaves broader than usual, and 6-10-nerved below. 

 My specimens are in fruit only, and possibly represent a new 

 species. 



Brachyloma ciliatum, Benth. Between Mount Gambier 

 and Glencoe. A small shrub 20-30 cm. high, apparently rare, 

 or at least localized. 



Leucopogon costatus, F. v. M. Keith (Dist. T). Appears 

 to be the first record of this species on the mainland. The new 

 specimens agree with those from Western Bay, K.I. Leaves 

 only 2-3 mm. long, ciliolate, often half -clasping by the cordate 

 base ; bracteoles small ; sepals oblong, ciliolate, longer than 

 the corolla-tube; ovary 2-oelled. 



Gentianaceae. 



Limnanthemum stygium, n. sp. (tab. vi.J. Herba 

 aquatica stolonifera, foliis radicalibus longe petiolatis ovato- 

 cordatis 20-25 mm,, longts; caule florifero unum folium 

 oblongum petiolatum racemum suffulcientem gerente; pedi- 

 cellis geminatis bracteolatis ad basm racemi folio ftorali vel 

 bracted amplexicauli suffultis; calycis segmentis ovatis 3- 

 nerviis S-Jf mm. longis, corollae roseae lobis margine fimbrill- 

 atis calycem vix superantibus ad basin staminum barbatis, 

 stigmate late bilobo, fructu ignoto. 



Dismal Swamp, 15 miles north of Mount Gambier. A 

 small water-plant, near L. geminatum, (R. Br.) Griseb., but
