Said to have been found at the head of Glen Curragh, Kerry, by 

 Dr. "W. Andrews, and there is a leaf of this plant in Mr. Ilewett 

 Watson's herbarium, sent by Dr. Andrews amongst a number of 

 leaves to illustrate the variations in form of S. umbrosa which 

 occur in Ireland. 



Ireland ? Perennial. Summer. 



A very remarkable plant, which appears to be quite intermediate 

 between the Hobertsonian Saxifrages and those of the Continental 

 group Aizoon, so that it has been suspected to be a hybrid of garden 

 origin. This supposition derives confirmation from the seeds being, 

 as far as is known, always abortive. The mode of growth is quite 

 similar to that of S. nmbrosa ; but the leaves are very different, IJ to 

 4 inches long, tapering insensibly from near the apex to the base, 

 with a very conspicuous pellucid cartilaginous margin, and with a 

 very distinct pore on each crenature. The flowers are larger than 

 in any of the forms of S. umbrosa, -| inch in diameter, and they are 

 arranged in more distinctly corymbose cymes at the extremity of 

 the long naked branches of the panicle ; the hairs too are gland- 

 tipped, and the sepals adhering to the base and to the ovary, and only 

 very slightly reflexed, give characters which show a nearer approach 

 to the Aizoontes than the Uobertsonige. The petals are conspi- 

 cuously dotted with red. The leaves are glabrous, except towards 

 the base from the point where the serratures cease and along the 

 petiole, where they are ciliated with hairs formed by the production 

 of the cartilaginous margin ; the pores on the crenatures have not the 

 covering scale distinctly white and crustaceous as in the Aizoontes. 

 Professor Babington, in his "Manual of Botany," places S. Andrewsii 

 in the section Avitliout barren shoots at the base : they are, however, 

 nearly similar to and as abundant as those of S. umbrosa.

Section IV.— HIRCULUS. Gaud. 



Stem leafy, with barren shoots at the base. Leaves narrow, 

 alternate. Sepals nearly free from each other and from the ovary 

 and reflexed, or combined at the base and there adhering to the 

 ovary and spreading. Plowers yellow or white. Hairs continuous 

 with the substance of the leaves.
