26 NOTES OP A TRIP TO MOUNT SEAVIEW, 



Potamophila parvijiora, R.Br., is an interesting grass, the genus 

 comprising but one species endemic in Australia. Bentham 

 {B.Fl. vii. 550) records it from "Williams River, R. Brown; 

 Hastings River, Beckler; the specimens few, and not seen in any- 

 other collection." I found it in fair quantity both in the Upper 

 and Lower Hastings. It is a tall, pale-coloured, erect, cane-like 

 grass, forming large tussocks in the water often several feet in 

 diametei'. It is cropped by cattle wherever they can reach it, 

 and is probably a nutritious grass. It occurs in the stony bed 

 of the limpid stream, always more or less submerged, probably 

 because cattle have eaten it out close to the bank. 



I now proceed to give some account of the Eucal3'pts found on 

 Mt. Seaview.* 



Eucalyptus aviygdalina, Labill. — This tree (Peppermint) occurs 

 on the summits of Mt. Seaview and of the other mountains 

 visited, being ver}'^ plentiful in some places. The bark is rough 

 at the Ijutt, and more or less blackish, hence it is sometimes 

 called Blackbutt, but it must not he. confused with the true 

 Blackbutt (^E. pilula^-is). The tree at the beacon on the summit 

 of Mt. Seaview, and officially referred to as Blackbutt, is E. 

 amygdalina. No seedlings or suckers were available, and barely 

 ripe fruit, but I do not doubt that the form of E. amygdalina on 

 these ranges is the var. latifolia (Deane and Maiden) described 

 in the Proc. of this Society [x. (2nd Ser.) 609]. The foliage and 

 fruits (which are shiny) are strikingly like those of trees in the 

 southern highlands, e.g., Queanbeyan, Delegate, also in the 

 Mudgee district and the highest jiarts of the Blue Mountains. 



This form from Mt. Seaview closely resembles the form formerly 

 described by Mueller as E. dives. 



E. acmenoides, Schau. (White Mahogany). — There occurs on 

 the sides of Mount Seaview a small-fruited form, with fruits up 

 to ^ inch in diameter and ^ inch deep. 



* I have dealt with the Eucalypts found on the New England table-land 

 during this trip in a paper read before the Australasian Association for 

 tlie Advancement of Science in Sydney in January last.
