3) Some mistakes or needed notes in the second edition of Trees of Seattle:


Page 30 cites some Acacia longifolia Sydney Golden Wattle ACACIA trees mixed with Blackwood ACACIA trees at the U.W. campus, and says the i.d. of these specimens is tentative . . . well, all the trees are Blackwood ACACIAS though they vary as if they are two strains.

Page 90 cites a Prunus pendula var. ascendens Wild Spring or Equinox CHERRY on Shilshole Avenue NW, flanked by a 'Whitcomb' CHERRY to the north and a 'Kwanzan' CHERRY to the south . . . but the 'Kwanzan' CHERRY is really a Yoshino CHERRY.

Page 99 cites 11 CHITALPA locations . . . but should note that 9 are cv. 'Pink Dawn' and only 2 are 'Morning Cloud' (U.W.: CUH, and 6507 2nd Ave NW).

Page 176 cites a Black HAWTHORN Cratægus Douglasii at the U.W. Medicinal Herb Garden . . . but it is a Shortspine Black HAWTHORN, C. Suksdorfii.

Page 191 cites a 51 foot-tall English HOLLY between 2215 and 2219 E Howe St . . . but it is between 2215 and 2209.

Page 226 cites a broad stout MADRONA north of 10054 Strone Ave N . . . but it should read 10058.

Page 227 says 2 young Anhwei MAGNOLIA at Miller Community Center may be this species . . . but they are not; their i.d. is unknown.

Page 234 cites 4 street-tree hybrid Kobus MAGNOLIA on Wallingford Avenue N . . . but these are really Wada's Memory MAGNOLIA as is noted on page 242.

Page 235 cites a street-tree Modern Hybrid MAGNOLIA 'Caerhays Surprise' on NW 60th St . . . but it is on NW 61st St.

Page 290 mentions a young Mexican OAK Quercus salicifolia Née . . . but it is not; it is really Q. salicina Bl. from Japan and Korea.

Page 312 cites 8 street-trees of Fraser PHOTINIA on Broadway E, north of E Lynn St . . . but these trees are long gone.
