1. E. Tetralix, Linn. Cross-leaved Heath. " Leaves four 

 in a whorl, revoluto-linear, ciliated; flowers capitate, pedi- 

 celled ; sepals linear, ciliated and pedicelled, downy ; corolla 

 ovate ; anthers awned, included ; style nearly included." Bab. 

 MSS. Br. Fl. 1. p. 176. E. Fl. v. ii. p. 226. E. Bot. t. 

 1014. 



Moist heaths and boggy ground. FL July, Aug. T? The (longer) 

 almost linear and revolute leaves of this species, noticed by Mr. Ba- 

 bington in the above description, serve along with other characters to 

 distinguish it from the following. 



2. E. Mackaiana, Babington. Many-branched Cross-leaved 

 Heath. " Leaves four in a whorl, ovate, ciliated, smooth ; flow- 

 ers capitate, pedicelled ; sepals ovate, ciliated, smooth ; pedi- 

 cels villous and downy ; corolla oblongo-ovate ; anthers awned, 

 included ; style exserted." Bab. MSS. 



On the declivity of a hill by the road side within three miles of Round- 

 stone, Curmamara ; Mr. W. M'Calla. FL July, Aug. T? . Speci- 

 mens of this presumed new species were left forme in Sept. 1835, by 

 Mr. Babington, and soon after I received others from the discoverer, 

 when at first sight it struck me as being different from any species I 

 was acquainted with. In its ovate, ciliated leaves, it much resem- 

 bles E. ciliaris, while in its mode of flowering and awned anthers 

 it agrees with E. Tetralix ; it however differs from that species in its 

 more shrubby habit and in the disposition of its branches, which, in- 

 stead of having the flowering ramuli generally springing from one 

 point (determinate ramosi) they are irregularly disposed and much 

 crowded towards the top of the main branches. Doctor Hooker, who 

 has kindly sent me a figure of this, is not as yet decided in his opinion 

 whether it will ultimately prove a distinct species from E. Tetralix. 

 There is however, I think, no doubt of its being at least a very distinct 

 variety. 



3. E. cinerca, Linn. Fine-leaved Heath. Anthers crested; 

 style a little prominent; stigma capitate ; corolla ovate ; leaves 

 three in a whorl. Br. Fl. 1. p. 176. E. Fl. v. ii. p. 226. E. 

 Bot. t. 1015. 



Dry heaths, woods and thickets, common. FL July, Aug. T? . 

 Stem from one to one and a half foot high in exposed situations j in 

 woods at Mucruss, it attains the height of five or six feet. Flowers nu- 

 merous, in dense leafy panicles, drooping, reddish-purple, occasionally 

 white. Leaves nearly linear, glabrous. 



4. E. mediterranea. Mediterranean Heath. Anthers with- 

 out awns, and as well as the style exserted ; corolla narrow, 

 urceolate ; bracteas about the middle of the peduncle ; calyx 

 coloured ; flowers axillary ; leaves four in a whorl. Bot. Mag. 

 *. 471.

$. On the western declivity of Urris-beg mountain near Roundstone, 

 Cunnarnara, Sept. 1830, covering a space of nearly three acres. It 

 has since been found by John Wynne, Esq. of Hazle-wood, and others
