<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: 'Arial','sans-serif'">
<I>Impatiens capensis</I> is, in my experience, a problematic species here
west of the Cascade Range in the Pacific NW. The densities of this sp.
are pretty amazing with the understory of riparian corridors often dominated
by it. I’ve been seeing more and more of it in the Willamette Valley and
surrounding ranges here in Oregon with seemingly little attention paid to
it.<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: 'Arial','sans-serif'">
Interestingly, some land managers still consider this species native here on
the West Coast, probably due to confusion with our native, <I>I.
ecalcarata</I> in some older floras and field guides. Ed Alverson of TNC
wrote a short comment in reply to a posting on <I>I. capensis</I> at the
Botany Photo of the Day website:<o:p></o:p></SPAN></P>

of the Cascades. Peter Zika addressed this issue in a 2006 paper, "The status

class=apple-style-span>Pacific Northwest coast", published in the Journal of
the Torrey Botanical Club, vol. 133 pp. 593-600. In fact, I. capensis is
spreading into the habitats of the uncommon native I. ecalcarata west of the
Cascades, and the two species are hybridizing. This has created a situation
where the native species is potentially being out-competed by both the
introduced species and by their hybrids. Zika has published another paper on
the hybrid, which he has named Impatiens x pacifica, see "Impatiens x pacifica
(Balsaminaceae), a New Hybrid jewelweed from the Pacific Northwest Coast of
North America", Novon vol. 16, pp. 443-448,
