100 Rhodora [May 



Lloyd & Underw., L. Chapmani Underw.), 1 a coastal plain extreme 

 of the species extending from Louisiana via Florida to eastern Massa- 

 chusetts but heretofore unknown northeast of Plum Island and 

 the famous Round Pond at Tewkshury (Massachusetts), where it 

 is one of a very notable group 2 of isolated coastal plain plants; and, 

 best of all, the tiny bladderwort, Utrieularia subulata, both the 

 showy form with expanded orange corollas and the cleistogamous 

 state with minute creamy or whitish flowers; for Utrieularia subulata 

 is one of the most characteristic plants of wet barrens all the way 

 from Brazil, via the West Indies, to southern New Jersey, north 

 of there an exceedingly rare species, known from a single station 

 on Long Island and very locally indeed on Martha's Vineyard, 

 Nantucket and Cape Cod (fig. 4). This was indeed pretty thrill- 

 ing and our excitement, as we were shown one after another the 

 different finds, quickly stimulated the curiosity of the brakeman, 

 who stopped for a lesson in a subject obviously quite new to his 

 experience. 



In his account of the distribution of forest trees of Canada, Robert 

 Bell stated that the northern White Cedar, Thuja occidental is, "is 

 absent from . . Nova Scotia;" 3 and in his enumeration of the 

 trees of Nova Scotia, Fernow 4 does not list the species. But in 



1 Many botanists maintain as distinct species the circuinpolar L. inundation and 

 the endemic American coastal plain L. adpressum and L. alopecuroides, although In 

 Britton & Brown's Illustrated Flora (ed. 2, i. 44) L. inundatum, var. Bigelorii, the type 

 of which is quite identical with Georgia, Florida and Louisiana specimens of L. 

 adpressum, is treated as a variety of L. inundatum : "Slender elongate forms, mainly 

 from New England . . . ; they indicate a possible transition into the next 

 species \L. adpressum]." On Cape Cod and in Nova Scotia the transition is very 

 apparent and no sharp specific line can be drawn between L. inundatum and L. 

 adpressum. L. alopecuroides, with its great development of bristly ciliation. would 

 seem, from its more typical specimens, to be well marked, but in his Plants of South- 

 ern New Jersey Stone says (p. 141): "We certainly havo a chain of connecting links 

 in our New Jersey bogs between L. chapmanii tor I., adpressum] and L. alopecuroides." 

 It is thus apparent that, in 1848, Tuckerman worked out the proper treatment of 

 these plants: 



"L. inundatum . . . . — (3. Waelorii, (mihi): majus, ramis subramosis elong- 

 atis, folds acuminatis sparsim denticulatis s. integris. L. Carolinianum. Higel. Fl. 

 Bost. p. 384. — Y. alopecuroides, (mihi): caule ramisque ut &. folds lineari-subulat is 

 basi sparsimque ciliato-dentatis. L. alopecuroides, L. . . . (Q.) Wet, sandy 

 margins of ponds; Plymouth, Oakes and Tuckerman; (also New Jersey?). — {*{.) 

 Florida, Torrey. . . . The variety alopecuroides, if this view be correct, is the 

 extreme southern American form of the species, the variety Bigclovii intermediate, 

 and perhaps not occurring north of Massachusetts, and <X. the extreme northern 

 state, common to us with Europe." — Tuckerm., Am. Journ. Sci. xlv. 47, 48 (1843).
