Nobody we know has ever = seen pallida for sure. There are old records for pallida from both Capes = Blomidon and Split. However, we have searched high and low in both = locations with no firm results. The only populations we found on = Blomidon are around the lower parking lot especially down the stairs at = the start of the Jodrey Trail where a wet area is good habitat, = supporting large numbers of specimens. All those there are typical = capensis. Up on the Cape proper we have found none even though there are = many areas of suitable habitat. At Cape Split there are lots of capensis = along the roadsides before you get to the new parking lot, along and off = the trail there are scattered specimens but few of them are in flower. = Half way up the incline to the top ridge is a wet area where several = little streams cross the main trail and create muddy footing. There, a = small population has some of the characteristics of pallida especially = in regard to the spur and nectary but the colour is a light orange. The = only large population ofpallida mentioned in the literature is on Isle = Haut. However, the cost of getting there is quite high unless a fair = sized group all contributed. > Incidentally, there is a large patch of Himalayan = Balsam on both sides of the final stretch of road to Cape Split which is = certainly spreading and a little further on, on the right a very large = area of Canadian Burnet spreading widely. Its white plumes of flowers = are very obvious right now. > All the best, Martin. --Apple-Mail=_8BECB52A-F0B1-4E99-A9AD-095AB874ACCC Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=windows-1252 <html><head><meta http-equiv=3D"Content-Type" content=3D"text/html = charset=3Dwindows-1252"></head><body style=3D"word-wrap: break-word; = -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">On = Sept. 3 Martin Thomas wrote me the following note in response to mine, = and he includes the Scots=92 Bay expanding colony of pink jewelweed = (Himalayan Balsam) that Ian McKay just reported.
