REPORT FOR 1913. 



469 



Callitriche truncata Guss. Westerham, Kent, June 25, 1913. — 

 C. E. Salmon. " A nice specimen, but, as usual, sterile when 

 occurring in running water." — ^J. Groves. " Probably the var. 

 occidentalis R. and F." — G. C. Druce. 



Peplis Fortula L., var. dentata Druce, in Npav Phyt. 1911, p. 313. 

 [Ref. No. 373.] Poaka Beck Reservoir, v.-c. 69 b, Sept. 5, 1913. 

 Not previously recorded for N. Lanes., and interesting as being totally 

 submerged for the greater pai't of the year. — W. H. Pearsall. 



Epilobium parvijiorum Schreb., forma. Sand dunes, Blundell- 

 sands, S. Lanes., v.-c. 59, Aug. 5, 1913. A robust plant with short 

 fruits and a remarkably pyramidal panicle. — J. A. Wheldon. "I 

 cannot distinguish this from type." — E. 8. Marshall 



Epilobium hirsutum ^ x montannin 9- Artificially produced first 

 generation hybrid. Cross made in 1911: grown at Tewkesbury, 1912-13. 

 Interesting as a contrast to the reciprocal hybrid distributed last 

 year. The flowers are well formed, the petals intermediate in size 

 and shape between the parents. A certain amount of pollen is 

 produced, but apparently no good seeds. The plant flowers early, 

 with E. montanum and before E. hirsutum. The shape of the leaves 

 and the pubescence differ distinctly from the reciprocal hybrid. As 

 in other hybrids, the long runners of E. hirsutum are recessive. The 

 plants are from 2-3 feet high, and bear a general resemblance in 

 habit to E. hirsutum. — R. H. Compton. 



Epilobium hirsutum L., var. villosisshnum Koch. Grown in a 

 Tewkesbury garden (side by side with typical E. hirsutum) from seed 

 collected by Mr R. S. Adamson at Hayling Island, 1911. Simple 

 hairs are much more abundant than in the type, especially on the 

 upper side of the leaves and the inflorescence ; glandular hairs are 

 proportionately fewer. The lower parts of the plant and the runners 

 show no noteworthy differences from the type. — R. H. Compton. 

 " An interesting form. The species varies much in hairiness." — E. S. 

 Marshall. 



Epilobium tetragonum L., var. stenophyllum (E. adnatum, forma 

 stenophylla Hausskn.) Mo7i. Epilob., p. 98 (1884). These plants are 

 obtained from seeds of a plant gathered at Hurst. (See Fl. Berks., 

 p. 230, 1897). They have proved constant in my garden. From 

 their narrow leaves and profusely branching habit they appear 

 varietally different from type. July 1913. — G. C. Druce. 



Epilobium rosnum Schreb., f. umbrosa Hausskn. (fide A. Bennett). 

 Lane side, back of Shavington Avenue, Chester, July 29, 1913. — C. 

 Waterfall.
