NOTES AND EXHIBITS. 



Mr. T. Harvey Johnston exhibited a series of plants showing 

 pathological conditions produced by the presence of minute gall- 

 mites, Phytoptus spp. [Eriophyes spp.) belonging to the family 

 Phytoptidcn — (1) pear-leaves showing "blisters" due to the action 

 of P. pyri Pag.(Tas.): (2) oranges showing "maori"(P. oIeivo7-us 

 Ashm. ; coastal districts of New South Wales) : (3) tomato 

 " rosette " (Phytoptus sp.; Sydney, Bathurst) : (4) Crowfoot 

 (Ranunculus sp.) showing minute brightly coloured galls along 

 the stem (New South Wales) : (5) Gmelina Leichhardtii, show- 

 ing a feltwork on the leaves (Berry; Dr. Cleland) : (6) Banksta 

 marginata, showing thickening of the bark (Hawkesbury River; 

 Dr. Cleland) : (7) Couch-grass (Cynodon dactylon) showing 

 ^' rosette " (Sydney) : (8) Casuarina sp., showing deformity of 

 Small branches (Sydney; Dr. Cleland) : (9) Eucalyptus sp., show- 

 ing small brightly coloured galls on petioles and backs of leaves 

 (Pambula, N.S.W.; W. J. Rainbow). 



Mr. J. H. Maiden exhibited a " cushion "-plant, locally known 

 as " Yai'eta," from subalpine Bolivia. It is described as a resinous 

 material used as fuel, and the locality given is *' Cerro Alto, 

 altitude 1600 feet," which, it is suggested, may be a mistake for 

 metres. It comes from a correspondent of Mr. G. S. Card, 

 Curator of the Mining and Geological Museum, Sydney. The 

 protective substance is not hair, as in the case of the Vegetable 

 Sheep of New Zealand, but resin. It shows no inflorescence, but 

 is probably a species of Azorella, of which three species are 

 recorded from Bolivia. Mr. Maiden also exhibited, for com- 

 parison, herbarium specimens of Bolax glebaria Covaevs., (Azorella 

 ccespitosa Cav.) collected by Dr. (now Sir) J. D. Hooker in the 

 "Erebus" and "Terror" Expedition. He also showed a fine 

 porti'ait of Robert Brown, litho. by Rud. Hoffmann, 1859, from 

 a contemporary photograph by Maull and Polyblank of London; 

 received from Dr. R. S. Rogers, of Adelaide. 



Mr. McDonough exhibited some fine specimens of the fruits of 

 Eadiandra glohosa[^.0. Laurine^e] from Mullumbimby, N.S.W., 

 .somewhat larger than any previously noted.
