Geasters. — In a series of papers on Geasters which recently ap- 

 peared in the "Gardener's Chronicle," Mr. Worthington G. Smith 

 has figured all the British representatives of this genus. The species 

 which is recorded in Grevillea, vol. i., p. 40, is considered distinct 

 from both G. lageniformis (Vitt.) and G. tunicatus (Vitt.), and for 

 it is proposed the name G. Michelianus (W. G. S.), it being re- 

 garded as identical with the plant Micheli has figured in his Nova 

 Plantarum Genera t. 100, f. 1, under the name Geaster major um- 

 bilico-fimbriato, and with the specimens published in " Erbario 

 Crittogamico ltaliano " (No. 343 and 979) as Geaster tunicatus 

 Michelianus. 



In the same communication there is a figure of what is regarded 

 as Geaster lageniformis, Vitt. This is a much smaller and more 

 delicate plant, differing from the majority of Geasters in possessing 

 perfectly round and smooth spores. It is comparatively a recent 

 addition to our flora, having been up to the present time only re- 

 corded from Devonshire, and, possibly, Norfolk.

 to former papers in " Grevillea." 



Dr. L. Rabenhorst, of Dresden, has for disposal some sets of 

 Chinese Lichens, collected in the neighbourhood of Saigon, Hong- 

 Kong, Wampoa, and Shanghai, by Rudolph Rabenhorst, in 1871-2, 

 and determined by Dr. Krempelhuber, of Munich. The price of 

 each set will be 5 thalers.
