Sept 8 62 Elizabeth sent me 3 spec of Lythrum hyssopifolium from different countries these all agreed with Kew specimens; so that I have seen 4 specimens. This species probably is not very improbably dimorphic.—

But E. sent me, a 4th spec. of L. Graefferi (named at Kew) with larger leaves & larger petals & longer flower than L. hyssopifolia; & differing quite in narrow smooth & longer calyx from L. salicaria— This was a short-styled form, with "shorter stamens" not projecting from calyx but much longer than stigma, & with longer stamens, about equal ascending half-way, (measured from base of calyx in comparison with L. salicaria) with between shorter & longer stamens of short-styled L. salicaria.

No doubt this is trimorphic & would have (in presnt form ) in on the form. The stigma half-way up calyx; in the second at mouth of calyx & in third some way projecting beyond calyx.— — Pollen of longer stamen about 7- 8/7000 of shortest nearly 5/7000

Conspicuous difference— Dryed plants rewetted by Boiling water.
