2i6 The Irish Naturalist. November, 



field collected by Mr. Waddell. They seem to go best with my var. 

 mollissimus ; as probably do the Westmeath (Knock Drin) plant, Linton !, 

 Mr. Marshall's from Mallaranny, West Mayo, and Mr. Bailey's from 

 Carnabridge to Portrush, Derry. 



R. pyramidalis,' Kalt.— 37. Lurgan, PraegerX Lane and bushy 

 ground near the reservoir on the Dublin road, Newry. 38. Saintfield, 

 WaddellX Aghaderg, Lett ! Abundant at Ballynanny, Anacloan. 

 Reported by Mr. Waddell as " common at Saintfield, and in most 

 parts of the county." 39. Cave Hill, DruceX Cushendall ("very 

 little"), F. A. Rogers \ 



R. Ieucostachys, Schleich. — 37. Lurgan, Praegerl Scarva. Near 

 Newry. 38. Aghaderg. Anacloan. Banbridge. Apparently common, 

 though often uncharacteristic, in 37 and 38. 39. Cave Hill, Belfast, &c, 

 Shoolbred ! 



Egr^gii. 

 This group, it will be seen, is more highly represented than any other. 

 R. Lettli, sp. (or subsp.) nov. — " R. Gelertii, Frider. , Letlii, subsp. 

 nov.," Wats. Bot. Bxch. Club, 1900-1901 Rep., p. 14. Stem high-arching at 

 first, stout, bluntly angled, striate, glaucous, clothed with long fine shining 

 hairs ; its acicles very unequally scattered, and stalked glands very rare or absent. 

 Prickles mostly subequal and nearly confined to angles, remarkably com- 

 pressed and straight, long, slender, nearly patent, hairy, occasionally gland- 

 tipped. Leaves usually snate-pedate, concave, pale greyish-green, very soft 

 beneath with close shining hairs, often greyish-felted at first ; petioles long, 

 with many unequal partly gland-tipped organs. Leaflets somewhat imbricate 

 at first ; terminal slightly obovate, with fairly long cuspidate-acuminate 

 point, subcordate base, and compound teeth ; basal shortly stalked. 

 Panicle long cylindrical, lax below and usually only slightly narrowed at 

 the top ; about \ ultra-axillary ; the lowest branches moderately long, and 

 nearly erect. Rachis with very close grey felt under the long hairs, armed like 

 the stem though usually much more glandular and aciculate, with some 

 of the long slender prickles gland-tipped ; the prickles almost invariably straight, and 

 mostly patent or subpatent. Sepals (like rachis and pedicels) remarkably 

 grey-felted, rejlexed, often long-pointed, usually quite unarmed and 

 eglandular. Petals narrow, white or faintly pinkish. Stamens exceed- 

 ing styles. Young carpels somewhat hairy. Fruit abundant and 

 excellent. 



While recalling R. Gelertii among the Egregii, and in earlier groups R. 

 Questierii and R. micans, this seems most closely allied to R. criniger 

 Linton, from which it may, however, without difficulty be distinguished 

 by the long remarkably compressed slender prickles, the somewhat 

 obovate terminal leaflet with more finely pointed teeth and less gradually 

 acuminate point, and the cylindrical panicle with stronger gland- 

 tipped organs, shorter more ascending lower branches, and broader 

 top. The extraordinary greyness of the whole plant is also a very 

 marked feature. 



Under Canon Lett's guidance I saw it in great abundance in Aghaderg, 

 Anacloan, and Banbridge parishes along the western boundary of Co.
