HOW — NOTES ON NOVA SCOTIAN BOTANY. 175 



3. Hornbeam or Iron Wood. In 1868 a tree was pointed out 

 to me close to Moose River, Annapolis county, near Clementsport, 

 as almost the only one remaining of many "hornbeam-trees" 

 formerly existing in the vicinity. The two species Carpinus, L.. 

 and Ostrya, Michel, are included under the term '* hornbeam," 

 but I cannot say which of these the tree belonged to. So far as I 

 remember it was 30 or 40 feet high at least, so that its size would 

 be that of the latter, but its growing on the side of a stream would 

 accord better Avith the recorded habit of the former. 



4. New station for Osmorhiza hrevistytis, D. C. In the 

 Herbarium above alluded to is a specimen of this plant from East 

 Mountain, Onslow, Colchester count)^ I have since seen it grow- 

 ing on Marble Mountain, C. B., and at Eedden's, near the bridge 

 at Kentville, King's county. 



5. A.ctcea alba. In Prof. Lawson's valuable Monograph of 

 the Ranunculacege of the Dominion of Canada, and adjacent parts 

 of British America, read before the Institute in Dec. 1869, it is 

 mentioned that Actc^a riihva is widely spread throughout the whole 

 Dominion, but A., alba is south western. Gray states that this 

 variety is more common southward, extending to Virginia and 

 Kentucky. It grows at three places in this vicinity, viz., Windsor 

 Falls, Butler's Mountain, and Nesbit's Island. 



6. Potentillas at Windsor and westward. At Windsor we have 

 P. JSTorvegica, P. Canadensis^ and P tridentata in abundance, and 

 more sparingly P. anserina, and P. argentea ; this last I have 

 only seen at one spot, but it is common westward, viz : at Kent- 

 ville and Coldbrook, King's county, and on the road as far as 

 Digby. P. anserina I found at the head of Bear River, Digby 

 county. 



7. Dalibarda repeyis. The Herbarium spoken of above con- 

 tains a specimen of this plant from Wilmot, Annapolis county. In 

 1868 I saw the plant at Jauvet Comeau's, Bloomfield, Digby 

 county. 



8. JSfasturtiii'm offimnale. Water Cress. This plant is men- 

 tioned by Gray as found in the United States " in brooks and 

 ditches, rare, escaped from cultivation, naturalized from Europe." 

 Last year I learned that it is plentiful in two brooks near the Three
