THE BOTANY OF HOWELL (BORA CREEK) : A TIN- 

 GRANITE FLORA. 



By J. H. Maiden, Government Botanist and Director of the 

 Botanic Gardens, Sydney. 



In a Presidential address I had the honour of delivering before 

 this Society, part of it* was devoted -to a scheme for a Botanical 

 Survey of New South Wales. This address was accompanied by 

 a botanical map of the State, divided into proposed botanical 

 counties, and it was, as far as I know, the first map of the kind 

 to be published. Some five years previously, in another place, 

 I had formally promulgated this idea of a botanical survey, and 

 in an early issue of the Agricultural Gazette of N.S.Wales will be 

 found an elaboration of the idea, together with a modified 

 botanical map of the State. 



Howell, the subject of my present paper, is (so far as I have 

 treated it), a tin-granite area extending in a 2- or 3-mile radius 

 from the Howell township. Howell is on the Bora Greek and is 

 19 miles south-east of Inverell. It is on the Western New 

 England slope, and is included in my E9, New England County.* 

 It commended itself to me for consideration in that it consists 

 of an unmixed geological formation; I record no plants not 

 collected on what geologists term the " tin-granite." 



The record is incomplete, yet I think it will be found useful. 

 Most of the plants have been collected by myself, and Mr. J. L. 

 Boorman, the Collector of the Botanic Gardens, has paid a second 

 visit to this interesting locality. Mr. R. Hart, Headmaster of 

 the local Public School, has sent plants from time to time. 



Howell township stands at an elevation of about 2,500 ft. 

 above sea-level, and its situation is very picturesque,"with solid
