■ also shortened to half the length of those borne by ordinary trees of 
this species. Arenaria Grxnlandica, Sprang., grows on all the ex- 
posed rocky ledges, and Clintonia borcalis, Raf., in a sphagnous swamp 
and also in the woods at the base of the hill. The shrubs mentioned 
above are also found on the summit. 
A broad, shallow pond, a mile or so north-east of the Point, on the 
table-land, well repaid exploration. Here the small form of the 
white water-hly, {Nymphiea odoraia, Ait,, var. minor, Sims) grows 
plentifully. Eriocaulon septangulare, With., Lobelia Dortmanna, L., 
and Isoetes echtnospora, Durieu, var. Braunii, Engl., were found in 
shallow water near the shore, and Drosera rotundifolia, L., with D. 
mtermedia, Hayne, var. Americana, D. C, in fine condition in the 
Cip/iagmim along the margin.

Arthrocladia villosa, Duby.— This beautiful species, which is 
nowhere very abundant, has been considered especially rare in 
America. A specimen, found many years ago gave it a place in the 
Nereis Boreali Americana of Dr. Harvey. It was not reported again 
until a single specimen was found by Mr. Collins a few years since 
at Falmouth Heights, Mass. In 1881 I found another solitary speci- 
men near the same place at Menanhant, a summer settlement in Fal- 
mouth. In 1882 I looked in vain for it all summer long, but a single 
plant was found that year by Mrs. Chambre. But the latter part of 
July this season, after a severe south-west wind which lasted several 
days, this rare plant was washed up quite abundantly. I secured 
and mounted over eighty specimens, and might have collected many 
more. Some of these are about fifteen inches in length and several 
are complete, having the holdfast. It seems probable that it grows in 
the deep water in the narrow part of Vineyard Sound, and is torn 
up only when there is an unusual disburbance of the water

Notes from N. Lower California.— On a recent trip into the 
mountains of Lower California, my father, H. C. Orcutt, and myself 
tound Quercus Palmeri, pungens and Emoryi abundant at an elevation 
of 4,000 to 6,000 feet, and as far south as San Rafael Valley, near 
where vye found Fholisma arenarium, Nutt., on the roots of Q. 
ralvieri. From north of the boundary, and south over a hundred 
miles by road, we found Adenostoma fasciciilattwi and sparsifolium 
still abundant, and, with them, Arctostaphylos pungens and Garrya 
flavescens, var. Palmeri, Watson. The lattfer we found from 2 to lO 
teet high. In general appearance of leaves and stalk (although the 
bark does not exfoliate, and is grayish) it closely resembles the man- 
zanitas, and we found it to have a similar large root, which only differed 
Irom that of our Arctostaphylos in being black instead of reddish 
colored.^^ Among the graceful piiions {Pimis Parryana), we found the 
sotole {ISl-ohna Pahncri) abundant and presenting the appearance 
of coarse grass growing near water, but in reality growing in the
