Hi Sherman & All, Aug 31, 2013
And that comment in Roland & Smith,"doubtfully native to N.S." , is =
in turn a contraction of Roland's (1944) "This climbing plant, used as a =
cover for fences and walls, often escapes to waste places and persists =
on rich river bottoms in the Central and Southern parts of the =
province."
I recall collecting in the early 50's and thinking, based on =
distributions north of the Canso-Digby line, that Dr. Roland was full of =
beans but once a guess is enshrined in print one must move heaven and =
earth to replace it by a second educated guess.=20
True it was used as an ornamental and true it does sometimes escape =
to waste places but why did it then migrate to undisturbed habitat, =
sometimes far from settlement, preferentially north of the Canso-Digby =
line ?
To back up to the start, it is native to North America.=20
In Gray's Manual 7ed (Robinson & Fernald, 1908) the range included =
N.B but not N.S. They note; "also cultivated for arbors and freely =
escaping".
In the period leading up to the 8th edition in 1950, Fernald =
collected extensively in N.S. but, so far as I know (can anyone verify =
this ?), his activity was entirely or almost entirely south of the =
Digby-Canso line. The 8th ed. did not include N.S. within the range, =
perhaps after having consulted Roland's Flora. =20
In a way the debate is a tempest on a postage stamp; recognized as =
native in N.B. for more than 100 years but stuck as perhaps not native =
in nearby N.S. I think it is both native and ornamental escape but in =
the end the current behavior of the plant is all that matters.

Subject: Re: [NatureNS] re "Wild Cucumber"
Zinck is probably reflecting the comment found in Roland and Smith's, =
The Flora of Nova Scotia, "doubtfully native to N.S." Taxonomy of =
Vascular Plants by Lawrence, refers to it, (Echinocystis (lobata)) as =
one species representing the Cucurbitaceae family in the U.S. Other =
references show it as being native to North America, e.g. Wildflowers =
of Ontario.

In answer to Richard's question, Zinck (1998) says that wild =

Texas. Cheers from Jim in Wolfville.
