 Plate CCXXXVII. 

 A. ciliata, var. Benth. Handbook Brit. Fl. p. 123. 



Rootstock simple or none. Stem proclucini* vciy short decumbent 

 barren shoots and rather short ascending flowering shoots. Lower 

 leaves oblanceolate, much attenuated towards the base ; the upper 

 ones ohovate-oblong or oval, all imbricated, sub-sessile, acute, 

 1-nerved when dry, fleshy, smooth and glabrous except that occa- 

 sionally there are a few hairs on the margins. Flowers few, in 

 dichotomous cymes (frequently reduced to 1 or 2 flowers) ter- 

 minating the stem and branches, with ovate or lanceolate leaf-like 

 bracts. Pedicels equalling or slightly exceeding the sepals, erect. 

 Sepals triangular-ovate, acute, with 3 ill-defined glabrous nerves 

 down the middle ; the lateral ones often scarcely perceptible ; the 

 margins very narrowly membranous and glabrous. Petals oblanceo- 

 late, exceeding the sepals by about half their length. Capsule ovate- 

 ovoid, about as long as the sepals. Seeds roundish-reniform, coarsely 

 shagreened. Plant glabrous, except the upper part of the stem and 

 peduncles, which have short hairs, some of them gland-tipped. 



On loose gravel. Very rare. On the gravel of a serpentine hill 

 immediately to the Korth of Baltasound, Unst, Shetland, where it 

 was discovered by the late T. Edmonston. " Pound in the Orkneys 

 by Sir U. Murchison and Mr. Peach " (Baker, in Report of Thirsk

 Heddle informed me that the island in which it occurred was 

 Korth Pionaldshay. 



Scotland. Perennial or Annual ? Summer and Autumn. 



Boot slender, producing a single stem. Stem dividing near 

 the base into numerous equal divisions, which are 1 to 3 inches 

 high. Leaves closely placed, \ to \ inch long, increasing in size 

 from the base of the stem to the commencement of the cyme ; when 

 fresh appearing nerveless, but showing a rather indistinct midrib 

 when dry. Flowers f inch across, white. Seeds roundish reniform.
