Lepidospekaia quadraxgulata, n.sp. 



South Brotliei>, John's River (J. L. Boormau, 6, 1915); Port Macquarie 

 (J. L. Boorman, 1], 1915). 



Stipes 1 111. altus, 2 mm. latus, foliis latioribus, 75 cm. longis, stipes t'oliaque 

 codiuu iiiodo quadrangulata. Panicula 2 ad 5 cm. longa. Bractea paniculae in- 

 feiior 1 — 5 ad 3 em. longa. Niix obovoidea triangularis, eostis prominentibus 

 Squamae angustae setaceae. 



Stem about 1 ui. high, under 2 mui. broad, Huely striate, smooth, 4-angled, the 

 edges slightly produced and rounded. Leaves 4-angled, broader and flatter than 

 the stem, from 50 to 75 cm. long, the rounded edges of the angles prominent, form- 

 ing a shallow channel more conspicuous on the broad side of the leaf. Panicle 

 from 2 to 5 cm. long, compound, dense, ovoid-oblong to pyramidal, branches few, 

 erect. Bracts of the inflorescence striate, the lowest 1| to above 3 cm. long, 

 the lamina oecnpying about half its lengfh, the upper ones gradually smaller. 

 Spikelets clustered, sessile, crowded on the panicle branches, 5 — 6 mm. long. 

 Barren flowers 1 — 2 below the jierfect one. Flowering glumes acuminate, 3 — 4 

 outer ones shorter and broader. Nut obovoid, 3-angled, the rite prominent, pale 

 when young, but gradually becoming mottled with brown. Hypogynous scales 

 narrow, frequently tapering into a seta. 



Its nearest affinity is L. Neesii Kunth., from which it is easily separated by 

 the quadrangular leaves and stem, though in some forms of L. Neesii the stems 

 show a degree of angularity. Quadrangiilar stems and leaves are represented in 

 the genus by L. tetraqiietrum Nees, an exceptional species placed by Bentham* 

 in his otherwise flat-leaved series Floribundae, a position to which it is entitled 

 by its inflorescence, an elongated panicle of 6 — 12 inches. The much reduced 

 compact panicle of L. quadrangulata is tliat of Bentham's series Tereticaules, 

 though it differs in the shape of stem and leaf from the other members of the 

 group, which have — as the series distinction indicates — -cylindrical stems and 

 leaves . 



Grkvillf.a punicea R.Br. var. crassipolia, n.var. 



Gosford (J. Purser, 9, 1899) ; Penang Ranges, Gosford (J. H. Maiden, (i, 

 1903) ; Road to Wiseman's Ferry, Gosford (A. A. Hamilton, 1, 1916). 



Leaves crass, rigid, flattened, from ovate to rotundate, J, to 2 em. long, the 

 intramarginal vein prominent and slightly tubereulate. A variety differing from 

 the typical Port Jackson form in the size and rotundity of the leaves, and the 

 conspicuous infra-marginal vein which gives the refiexed leaf margin a spreading 

 rather than the typical recurved habit. This variety appears to be confined to 

 the neighbourhood of Gosford. 



Hakea saligna R.Br. var. angustifolia, n.var. 



Woronora Rivei;, Heathcote (A. A. Hamilton, 10, 1915). Growing among 

 boulders in the river bed. 



A compact shrub 2 m. high. Leaves narrow, I to 1 dee. long, 3 — 5 iniu. 

 broad, rigid, almost veinless. Fruit carpels small, 2 cm. long, 1 — 1] cm. broad, 

 nearly smooth, the beak straight or barely produced, approaching the fruit of H. 

 microcarpa R.Br. An example from Lawson (A. A. Hamilton, 9, 1914) of 



•Fl. Austr., vii., p.385.
