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. In 2017, I was informed that the Blackwood above the Burke-Gilman Trail is really Acacia implexa Benth. known as Lightwood, or Hickory Wattle.

Page 39 cites a Platycladus orientalis 'Sanderi tree "believed to be this cultivar" . . . actually it is a Sawara CYPRESS: Chamæcyparis pisifera 'Squarrosa Dumosa' and an even taller one (17.5 feet in 2009) is at Kubota Garden Park.

t

Page 44 cites an Azara microphylla "2702 10th Ave W" . . . actually it is at 2707.

Page 90 cites a Prunus pendula Weeping CHERRY at 2046 42nd Ave E . . . but it is really an own-root 'Pendula Plena Rosea' cultivar --the only own-root specimen I have seen of this clone.

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). Moreover, it was reported in 2006 that the two clones have different backgrounds. 'Morning Cloud' was Catalpa speciosa x Chilopsis linearis ; while 'Pink Dawn' was (Catalpa ocata x C. speciosa) x Chilopsis linearis.

Page 146 cites 5 'Pioneer' Hybrid ELMS at Green Lake . . . but they are cv. 'Frontier' and there are 6, the tallest 37 feet in 2008.

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 181 cites a Hupeh HAWTHORN Cratægus hupehensis at 6837 30th Ave NE . . . but it is at 6811 really, and the hydrangea shrubs are now gone.

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

Page 205 treats Rocky Mountain JUNIPER Juniperus scopulorum and cites various specimens . . . but in Dec. 2007 a botanist "split" this species, making the Puget Sound native population J. maritima. The Arborteum has both species; the other Seattle specimens cited in my book are all J. scopulorum.

Page 226 cites a broad stout MADRONA north of 10054 Stone 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 299 mentions a young OLIVE TREE Olea europæa L. . . . but as of August 2010 is not; it is a weeping willowleaf PEAR TREE. Either am olive tree was replaced, or I made an error 5 years ago. I do not know.

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

Page 368 cites various 'Robin Hill' SERVICEBERRIES . . . but it seems all these trees except those at the Arboretum are really Amelanchier lævis Lustre® (they are mislabeled at nurseries).

Page 392 cites an UMBRELLA PINE at 20th Ave E & E Prospect St --it should read 21st Ave E.
