Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 1 Sep 2004 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Richard J. Jensen, in Flora North America 3:452 (1997), treats Quercus parvula, Quercus parvula var. shrevei, Quercus parvula var. tamalpaisensis, and Quercus wislizeni var. frutescens as synonyms of Quercus wislizeni, with no infraspecific taxa recognized in Quercus wislizeni.
Correspondence 2 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by John M. Tucker see Comment 2
Editorial Comments 2 Correspondence 2 indicates that for The Jepson Manual [Ed. 2] Quercus wislizeni A.DC. var. frutescens Engelm. is to be recognized as native to CA.
Correspondence 3 18 Apr 2018 e-mail from Al Keuter see Comment 3
Editorial Comments 3 Correspondence 3 includes a link to a paper (Am. J. Bot. 104(10):1581-1595. 2017) in which it is stated, "Three individuals sampled from Southern California form a well--supported clade sister to remaining Q. wislizeni samples, consistent with previous interpretations that these southern trees are genetically distinct. However, this southern grouping does not correspond morphologically to Q. wislizeni var. frutescens as described by Engelmann, with neither PCA data set distinguishing these samples from the rest of Q. wislizeni." [Therefore, Quercus wislizeni A.DC. var. frutescens Engelm. is to be treated as a synonym of Quercus wislizeni A.DC..]
