Plentifully at Cave hill, near Belfast. Mr. Templeton. At Staffa, 

 and near Kirkaldvj also on the Giants' Causeway, where Mr. 

 Templeton had previously found it. Dr. Hooker. 

 Perennial. July. 



Root of numerous rather woody fibres, creeping along the unequal 

 surface of the basaltic rocks, under a superincumbent soil of 

 about five inches of decayed rock and zeolite. Mr. Templeton 

 could never perceive the roots to be parasitical. Dr. Hooker 

 observes that this species is entirely confined to basaltic rocks, 

 covered with a very thin coat of earth. The whole plant is of a 

 rusty purplish red, the bracteas rather browner. Stem a foot 

 high, tumid and densely scaly at the base, clothed above with 

 glandular viscid hairs. Fl. about 20, not very densely spiked, 

 their scent powerful, resembling a honey-suckle, or pink. Cal. 

 of 2 narrow, lanceolate, undivided leaves. Cor. but little in- 

 flated ; upper lip cloven, lower in 3 rounded segments, all the 

 margins crenate, and fringed with short glandular hairs. Fllam. 

 fringed and glandular at the base ; Dr. Hooker says at the 

 summit also. Anth. and stigma red; the latter sometimes with 

 3 lobes. Style partially glandular and hairy. Germen smooth.
