R. criniger, Linton. Whinnj Hill, Aghaderg Glebe, 

 Co. Down (Eef. No. 17), July 20, 1897. " I think a form 

 of R. Koehleri, allied to var. cognatus, though the subsessile 

 basal leaflets are abnormal in that species. Ref. Nos. 2, 

 35, 37, 42 and 43 seem the same."— W. M. R. 



R. radula^ Weihe, var. echinatoides^ Rogers. In a 

 rhododendron bush, Aghaderg Grlebe, Co. Down (Kef. No. 

 45), July 30, 1897. "Apparently the same form as Mr. 

 Lett's No. 16, 1896. See last report'"— VV. M. R. 



R. Neiohoiddii, Bab. and allied forms. "The Aghaderg 

 July 29, 1895 ('H'), plant, seems identical with our Salop 

 and Cheshire Newhouldii. The Mill Hill Lane, Ballintag- 

 gart, Aug. 9, 1895 ('M'), plant seems a strong form of 

 the same, somewhat gomg off towards R. Bahingtonii, In 

 the 30th June, 1896 ('3'), plant we have nearly, if not 

 quite, the same panicle as in ' H,' with considerably 

 different stem pieces. Rather further away apparently, 

 though still somewhat allied, are the two 1897 plants with 

 Ref. Nos. 16 and 18."— W. M. R. 



R.Juscus, W. and N. Mill Hill Lane, Ballintaggart, 

 P. of Aghaderg, Co. Down (Ref. No. 4), July 16, 1897. 

 " I think most probably a form of R. Newhouldii^ Bab., 

 though hardly identical with any of the plants above re- 

 ferred to under that name." — W. M. R. 



Nos. 1, 5, 6, 8, 13, 24, 29 and 38 (1897) seem only 

 slightly varying forms of one type and not separable from 

 Nos. 15, 16 and 20 of 1896. A year ago I wrote of these 

 1896 specimens, " Distinct from and yet in some respects 

 strongly recalling R. liibernicus^'' but I could suggest no 

 name. It appears to be a well-marked plant, in panicle 

 armature approaching R. Koehleri, though in stem, leaves, 

 &c., differing from that as much as it does from R. hibernicus. 

 Now that I have a good series of specimens I shall be in a 

 better position for further study, but it is most desirable 

 that Mr. Lett should carefully trace its distribution and 

 range of variation in his neighbourhood, as it may prove to 

 be a new and widely spread species in N.E. Ireland. The 

 degrees of variation in stem armature are especially re- 

 markable. No. 46 (1897) seems also to belong to the series, 

 near No. 16 (1896), though with different leaves. No. 44 

 may also be an allied weak form. — W. M. R.
