raria specimen I possess from Bayonne, kindly given to me by Sir 

 Wm. Hookei - , but which were suffered to become involute in drying, 

 which they never are naturally, and are, besides, firmly glued to the 

 paper. May not the leaves be occasionally a little rough-edged, both 

 in European and American specimens ? 



Andropogon Ischaemum I should never be surprised to hear had 

 been detected in the south-east of England. 



Leersia oryzoides. Tn and about the grassy or reedy margins of 

 rivers, brooks, ditches and ponds, in swampy meadows, wet hollows, 

 and other marshy places; very rare ? In many parts of the Boldre 

 River, West Hants, in great plenty, 1849 and 1850. Since the ac- 

 count of my finding this extremely curious and interesting grass with 

 us was published in this journal for November, 1849 (Phytol. iii. 681), 

 my anticipations of detecting it in increased frequency and abundance 

 have been amply realized. I am now enabled to announce it as 

 abundant in the Boldre River, for nearly three miles along the stream 

 above and below Brockenhurst Bridge. In tracing the plant above 

 bridge I commenced, August 24, with the southernmost tributary, or 

 branch of the river, which diverges to the left from the main stream, 

 in a westerly direction, at the west corner of New Park Inclosure, and 

 is known as the Rhinefield Water, along which I found the Leersia 

 in plenty, at distant and irregular intervals, for about a mile and a 

 half, on both banks, becoming more frequent as I ascended the stream, 

 and growing chiefly where the banks expanded into small, marshy 

 flats, as near the Aldridge Inclosure, above Rhinefield Lodge, but 

 ceasing entirely higher up, where, on approaching Markway Bridge, 

 the country assumes more completely the moorland character. Here 

 the Leersia grew very large and luxuriant, amongst Myrica Gale and 

 other swamp shrubs, always in or close to the edge of the stream, and 

 remarkably erect, the panicles fully formed, but no portion of them pro- 

 truded from the sheaths. Descending the river, we first find the Leersia 

 again at Brockenhurst Bridge, as described in a previous communica- 

 tion ; here are two moderately sized tufts of it only, growing out of 

 abundance of Isnardia palustris,* just under the railing at the Brocken- 



* I was fortunate to discover a third Hampshire station for the Isnardia on the 

 25th of August last, namely, in a damp spot (apparently a water-way in the winter 

 months) in the heart of the New Forest, between two of the branches or tributaries of 

 the Boldre River, a little to the north-west of New Park Inclosure, and about two 

 miles in the same direction from Brockenhurst Bridge, an exactly similar locality to 

 that of the Isnardia on Petersfield Heath, and where it occurs, as there, in plenty, 

 with Helosciadiuin inundatum and Peplis Portula for its associates. On this station
