*i. Rock Rimmon, in West Manchester, is an exposed ledge, 

 precipitous on the east and south sides and inclined gradually 

 on the west and north sides. It is an island of rock in a lake 

 of gravel. Close to the eastern base is a small, boggy swamp. 

 It follows that here, within a ver}^ limited area, are ecological 

 conditions favorable to a great variet}^ in the flora. The follow- 

 ing names of rarer and unexpected species may be of interest : 

 Quercus Prinus L., Rhus venenata DC, Asplenium platyneu- 

 ron (ly.) Oakes. (rare in this vicinity,) Syntherisma Miforniis 

 (L.) Nash., Eragrostis capillaris Nees., Chrysopogon nutans 

 Benth. 



*2. Dr. A. A. Briggs of Andover, while wheeling along the 

 river road in Bow, near the Hooksett line, found several tufts 

 of this species and kindly furnished the compiler with speci- 

 mens. The latter soon after (Sept. 22) visited the locality and 

 found the grass scattered along by the side of the road, which 

 there runs close to the river, for about a quarter of a mile. In 

 all there were 19 tufts, large and small. This abundance would 

 indicate that it must have been established for some time. The 

 land in the vicinity is subject to overflow from freshets, and is 

 largely covered with very fine sand. Most of the grass was 

 growing in this sand. 



*3. Two forms of Sporobolus of this group are common in Man- 

 chester and Concord, one appearing to answer the description of 

 6*. neglecttcs Nash., the other that of ^. vaginoeHorus (Torr.) 

 Wood. In the former the glumes are nearW of equal length ; 

 in the latter they are of four decidedly different lengths, increas- 

 ing regularly in length from the short lower empty glume to the 

 long-acuminate almost awned palet. Frequently the palet is so 

 exaggerated as to strongly resemble that of ^. asper. The two 

 forms usually grow separately. The one which is here provis- 

 ionally called 5". vagincetiorus sometimes forms a close turf in 

 moister situations, thus contrasting with the usual scattered
