792 TWO NEW SPECIES OF PLANTS FROM N.S.W., 



This hitherto undescribed Jacksonia is in habit and ramification 

 similar to J. angulata ; but the calyces of the latter are more 

 distinctly stalked and have their five segments equally long, 

 linear-lanceolar, more pointed and slightly downy inside, the 

 corolla is more evidently surpassed in length by the calyx, the 

 lower petals being the shortest and dark purple. The ripe fruit 

 may also prove to be different. In the characteristic of the 

 upper lip of the calyx not being deeply divided J. Stackhowii 

 approaches, among the 33 congeners now known, only J. odontoclada 

 and J. ramosissima. 



Several instances are known of very remarkable repetitions of 

 West- Australian forms of plants occurring in the most eastern 

 regions of Australia, though no similar species have been dis- 

 covered in the wide interjacent spaces, the imitative species being 

 however not identical. Even quite recently the genera Boronia, 

 Agonis, Brachyloma and now also Myoporum, have furnished such 

 examples. To these instances another has now been added by 

 Captain Stackhouse, E.N., who sends from near the entrance of 

 the Clarence River the above characterised Jacksonia, which he 

 rightly recognized as nearest to the West- Australian J. angulata. 

 The same plant had been collected some years ago by Mr. C. 

 Moore and Mr. W. Carron on sand ridges near Cape Byron, and 

 lately the Rev. B. Scortechini has found it also within Queens- 

 land boundaries. 



Myoporum Bate;e (Sect. Bisoon.J 



Shrubby, erect, glabrous; leaves scattered, elongated, narrow- 

 lanceolar, of thinly chartaceous consistence, minutely serrulated, 

 decurrent into a very short stalk ; flowers from 4 to 1 in each 

 cluster, somewhat or considerably longer than their thin stalklets ; 

 segments of the calyx narrow-lanceolar, nearly three times shorter 

 than the corolla ; the lobes of the latter semiovate-orbicular, 

 glabrous, about as long as the tube ; throat of the corolla very 

 scantily short-downy ; filaments about as long as the corolla, but
