Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 8 Nov 2001 e-mail from Barbara Ertter (including e-mail from Steve Broich) see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Steve Broich, author of Lathyrus for Flora North America and possibly Jepson Flora Project, recognizes Lathyrus sulphureus var. argillaceus.
Correspondence 2 8 Nov 2001 e-mail from Barbara Ertter see Comment 2
Editorial Comments 2 Correspondence 2 includes evaluation of hairy specimens identified by various workers as Lathyrus sulphureus, and therefore possibly assignable to Lathyrus sulphureus var. argillaceus.
Correspondence 3 10 Dec 2002 e-mail from Jeff Greenhouse see Comment 3
Editorial Comments 3 Correspondence 3 indicates that, according to Barbara Ertter, Steve Broich (author of Lathyrus for Flora North America) has returned to UC/JEPS six sheets determined by him in June 2002 to be Lathyrus sulphureus var. argillaceus, and that these sheets represent a California distribution of n SN, NCoR .
Correspondence 4 1 Dec 2004 e-mail from Misa Ward see Comment 4
Editorial Comments 4 Correspondence appended verbatim is pertinent to The Jepson Manual [Ed. 2] account: "Move to List 1B? Location, rarity, and endangerment information needed; does plant occur in NEV Co.? Fewer than ten specimens exist in California herbaria. Taxonomy poorly understood; see L. sulphureus in The Jepson Manual. See Flora of California 2(1):393 (1936) by W.L. Jepson for original description."
Correspondence 5 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by Kelly Steele see Comment 5
Editorial Comments 5 Correspondence 5 indicates that for The Jepson Manual [Ed. 2] Lathyrus sulphureus A. Gray var. argillaceus Jeps. is to be treated as a synonym of Lathyrus sulphureus A. Gray, despite the fact it has been recognized and confirmed for California by the author of the genus for Flora North America.
