* I've also been interested in this problem, and I accumulated only
about a dozen locations for T. angustifolia in Nova Scotia from our
travels there in 2010. The same condition holds in New Brunswick, where
the uncommonness of T. angustifolia and hybrids is considered
unexceptional by local botanists - e.g. Gart Bishop
<gartali@NBNET.NB.CA> - even while it strikes those of us from Ontario
as astonishing.
Going down the St Lawrence along the TransCanada, T. angustifolia
continues to be abundant to Riviere du Loup, but once you're over the
mountains to Edmundston it's uncommon all the way to Annapolis Royal.
