198 president's address — section d. 



" The object of my paper is only to record those plants which 

 in the Northern Territory have, np to date (1891), escaped cultivation, 

 or which have been introduced unintentionally." 



He makes a special list of the plants introduced during the last 

 20 years, amounting to 62 species. 



4. " Narrative of an Exploring Tour across Melville Island, North 

 Australia, with Notes on its Botanv." M. Holtze (Proc. R.S., S.A., 

 XV., 114-20). 



The tour took place in October, 1887. The list of plants enume- 

 rated is 170, and the author remarks that no orchids (o) were observed, 

 and, with the exception of Lycopodium cernuum, no plant which he 

 had not previously observed on the mainland. The author states 

 that his trip was a hurried one, and that he had not much opportunity 

 for collecting. 



5. " List of Plants collected by Dr. Stirling in Central Australia 

 between Frew Ponds (lat. 17°) and Mount Stuart (lat. 22°) on the 

 Transcontinental Telegraph Route." Tate (Proc. R..S., S.A., XV., 

 262). Twenty-two species are enumerated. 



6. " Notes on the Fertilisation of some North Australian Plants." 

 N. Holtze (Proc. A.A.A.S., VII., 566-69). The plants are— Grevillea 

 chrysodendron, R. Br. ; Sccevola Koenigii, Vahl. ; Goodenia furpuras- 

 cens, R. Br. ; Stijlidium, Mimulus JJvedalix, Benth. ; Dolickandrone 

 fiUformis, Seem. 



7. " On a New Dilleniaceous Plant from Arnheim Land, North 

 Austraha," by Mueller and Tate (Proc. R.S., S.A., V., 79). {Pachynema

10. " Diagnosis of a New Genus of Verbenacese from Arnheim

 to Premnn. 



A paper entitled "The Sundew and the Rainmakers of North 

 Australia," by F. Antoine {Oesterr. Bot. Zeitschr., May, 1879), may be 

 referred to. I have not seen it. 



Biographical Notes. 

 The Hoitzes (father and son) have done good work in the investi- 

 gation of the flora of the Northern Territory. Maurice was first in 

 charge of the Botanic Garden, Port Darwin, and is now in that of Ade- 

 laide. His son Nicholas has succeeded him in the former post. Inspec- 

 tor Foelsche collected eucalypts mainly, and his work is referred to in 

 the " Eucalyptographia." These three and Henne are happily living; 

 the others have passed away. 



(o) Ml-. Nicholas Holtze informs me that he has seen the following orchids on 

 Melville Island : — Dendrobium dicupum, F. v. M., and D. Johannis, Reichb, var. 

 He concurs in the view that the island is botanically practically a part of 

 the mainland.
