262 NOTES FROM THE UOTANIC GARDENS, SYDNEV, 



H. saligna, a spreading tree 6 m. high, has leaves from J to IJ Jec. long and 1 to 

 nearly 3 cm. broad, distinctly veined, and fruit carpels 3J cm. long. 2 cm. broad, 

 covered witii large prominent tubercles, the beak recurved. Specimens in the 

 National Herbarium forming connecting links are from Cockle and Cowan Creeks 

 (W. F. Blakely, 3, 1915), "taU slender shrubs 15—20 ft." (CoUector's note), 

 with narrow acuminate leaves, the venation indistinct, and comparatively large, 

 prominently tuberculate fruits; Nowra (J. L. Boorman, 1, 1915). "a small tree 

 32 — 14 feet'' (Collector's note) with short acute leaves, midway in width between 

 the Lawson and Heathcote specimens, and small fruits with an elongated beak, the 

 tubercles less prominent than in the examples from Lawson. Bentham's descrip- 

 tion of H. saligna* may be interpreted to include all the forms here reviewed, 

 but the morphological differences between the typical specimens from Lawson, and 

 those from Heathcote appear to be sufficiently pronounced to warrant a vsrietal 

 distinction. The figure presented by Mr. Maidenf is probably the nearest ap- 

 proach to the type available. 



Pdltenaea ferruginea Rudge. 



Trans . Linn . See, xi., 300, t. 23 . 



Rudge's species is upheld by De Candolle,t who quotes Sieber's n. 420, but is 

 reduced to a variety (latifolia) of P. villosa Willd. by Bentham.§ The latter aho 

 mentions Sieber's n. 420. He bases his varietal distinction on the smaller, very 

 pubescent leaves, from narrow cuneate to broadly obovate, together with the larger 

 flowers of the variety We have in the National Herbarium a series of specimens 

 collected in the neighbourhood of Glenbrook, which agree with Rudge's figure, and 

 conform to his description, viz., Lapstone Hill (J. H. Maiden and R. H. Cam- 

 bage, 10, 1904); Glenbrook (W. F. Blakely, 10, 1913; A. A. Hamilton, 11, 

 1914); Blue Mountains, without specific locality (E. Betche, 12, 1882). P. vil- 

 losa has a wide range and as a consequence shows considerable variation, but none 

 of the numerous specimens in the National Herbarium collection which were ex- 

 amined approach, either in habit or foliage, the form under review. The pen- 

 dulous branehlets and narrow concave leaves of the typical P. villosa are replaced 

 by an erect branching habit and leaves — as in Rudge's figure — rotund, slightly 

 emarginate, and much larger than those of P. villosa typica. The hairs on the 

 leaves of the typical P. villosa are short, erect, and bulbous at the base, and the 

 flowers entirely yellow. In P. ferruginea the leaf hairs are long, weak, and 

 appressed, and the carina of the flower is rust-coloured . Rudge gives some prom- 

 mence to certain dots (sub-lente punctata) on the leaves of his species, including 

 details in the plate showing both surfaces of a leaf to demonstrate this charac- 

 ter. These dots arc filso discernible in a greater or lesser dcgi-ee tliroughout the 

 series of specimens of P. villosa examined. It will be seen that we have a difTor- 

 ence in the habit of the plant, size and shape of leaves, size and colour of flow- 

 ers, and a distinct vestiture separating these plants. When, after the passing of 

 a century, examples are found in the neighbourhood in which Sieber (upon whose 

 n. 420 the species is founded) is known to have collected, which arc the counter- 

 part of those figured by Rudge, it would appear that the characterization is
