840 NOTES ON A NEW SPECIES OF CALLITEIS, 



Hah. — New South Wales : Tal Tal Mtn., and Gowie Range, 

 B3^1ong, near Rylstone (J. Dawson, L.S.). 



This pine tree was first brought under my notice in 1893 by 

 Mr. J. Dawson, L.S., of Rylstone, who discovered it at the 

 localities above given. As I had, prior to this, collected four 

 other species of Callitris, i.e., C. calcarata, R.Br., C. glauca, 

 R.Br., C. cu2)ressifoTmis, Vent., and C. MueUeri, Parlat., in this 

 district, in fact, close to where this species occurs, it was easily 

 seen that its characteristic branchlets and fruit differentiate it 

 from any of these. In the fineness of the branchlets it approaches 

 C. glauca, R.Br., and C. robusta, R.Br., but it lacks the glau- 

 cousness so characteristic of the former species, and the tubercu- 

 late, valvate cones of the latter, and is always found at higher 

 elevations than these, as it occurs on ridges or rocky mountains 

 in company with C. calcarata, R.Br., which species, however, 

 extends on both sides of the Coast Range and well into the 

 interior, whilst this species so far has only been found on the 

 eastern slopes. The terete branchlets differentiate it from C. 

 calcarata, R.Br., and C. MueUeri, Parlat.; and the fruits from 

 C. glauca, R.Br., C. rohusta, R.Br., and C. cu^Ji'essifurmis, Vent. 

 The fruits show a remarkable likeness to those of C. MueUeri, 

 but the branchlets of the two bear no resemblance, and this remark 

 applies equall}' well to C. calcarata, R.Br. 



Concerning the other species of Callitris enumerated in the 

 ' Index Kewensis,' the differences are too obvious to be mentioned. 



Summarising its specific affinities and differences, it has 

 terete (but finer and without the glaucous) branchlets similar to 

 those of C. glauca, R.Br., and C. robusta, R.Br., and fruits 

 identical with those of C. MueUeri. The long, fine, drooping 

 branchlets occasionally give it a willow-like appearance. 



In botanical sequence it should come, perhaps, between C. 

 robusta, R.Br., and C. MueUeri, Parlat. 



This Callitris so far appears to be very local, for after a rather 

 exhaustive botanical survey of the Pines of this State undertaken 

 by me it was not found in any other locality, and there is no
