JEPJCRIS IMPRESS J, Labill., fl. plena. 
Mr. W, Hemsley, of Kew, has kindly directed my attention to wild 
specimens of this Epacris^ existing in the Hookerian herbarium, and 
supplied by Dr. F, Muller. It is the first instance of a genuine Aus- 
tralian plant with double flowers.

RYPERICUM UNDULATUM. 
Mr. T. P, Lucas scuds me a specimen of H, nndulatum^ gathered 
near Launceston, Cornwall. He and his fatlier, the Kev. S, Lucas, have 
known it there ever since 1859 or 1860, but had not detei-mined its 
name before the notice of the plant in this Journal.

POA BALFOURIL 
A Grass collected by N. Lund "in montibus ad Varanger, in Fin- 
markia orientali, 184)3," is Poa Bal/oum, Parn. He named it P. 
casia, Sm., var,^ which I am convinced that it is not. If not a dis- 
tinct species, it must be joined to P. nemoralis. Nevertheless, Ander- 
son says, '' P. Balfourii , . . vix a formis admodum vegetis snbalpinis 
P, ccesi(je distinguenda est." If he refers to such specimens as these 
of Lund for P. casia, that opinion is correct, otherwise it seems erro- 
neous. It is probable that Ledebour means P. Balfourii by his P. 
ccBBia^ for he gives to it " spiculis lanugine copiosa/' and most of the 
characters distinguishing P. Balfourii from P. C(sda^ Sra.

CHAEAS FEOM CARACAS. 
Professor Alexander Braun, in acknowledging the receipt of some 
Charas which M. Ernst, of Caracas, Venezuela, forwarded to him 
through us, writes; — "The neighbourhood of Caracas is very rich ia 
Charas, as you know, from the synopsis I have given in the Proceed- 
ings of the Berlin Academy for 1858. Of those sent by M, Ernst,
