c Hrusa et al., ms later published in Madrono 49(2)61-98. 2002: DISTRIBUTION: SnFrB, CCo.; STATUS: possibly naturalized, gen. spreading vegetatively.; NOTES: Widely planted and often persistent.

d Hrusa et al., Madrono 49(2)61-98. 2002: DIST: CCo, SnFrB: Hrusa et al. Current Status: Persistence tenuous: DOC: Contra Costa Co.: Berkeley-Oakland Hills, Grizzly Peak Boulevard ca. 1/4 miles south of Lomas Cantadas junction, dense patch on east side of road at edge of mixed scrub, el. ca. 100 ft. June 25, 1993, B. Ertter 11907 (UC); San Francisco Co.: Howell, J.T. et al. (1958, p. 102); Thomas, H. (1961, p. 239): NOTES: Gen. spreading vegetatively in California where it is widely planted and often persistent. Fully naturalized and spreading by seed in Oregon and Washington States, but similar behavior not confirmed in California.
Initial Editorial Comments sometimes included in Clusiaceae (Guttiferae), as in Kartesz & Meacham; two records in SMASCH, JEPS96231, UC1618342 (both Barbara Ertter 11907, 25 Jun 1993, Lomas Cantadas, Oakland-Berkeley Hills, Contra Costa Co.); according to Source d, in California persistence tenuous, but also said to be "Gen. spreading vegetatively in California where it is widely planted and often persistent. Fully naturalized and spreading by seed in Oregon and Washington States, but similar behavior not confirmed in California.", so occurrences possibly qualify for inclusion in the flora according to criteria employed by Jepson Flora Project (20 Feb 2003)
