It may be recognized by its thickened rootstock with tuber-like roots 

 — characteristic of the Telephium group — and its leaves and flowers 

 as above. 



Description. — A glabrous herbaceous perennial. Rootstock thickened, with 

 small carrot-shaped tuberous roots. Stems annual, many, 4-6 inches long, 

 erect or arching, round, smooth, unbranched, leafy. Leaves alternate, fleshy, 

 shortly stalked, linear-lanceolate, blunt, flat on face, rather rounded on back, 

 J to I inch long, with a few large scattered teeth ; upper leaves narrower, very 

 fleshy. Inflorescence flattish, corymbose, i inch or more across, rather dense. 

 Buds ovate, blunt, pink. Flowers shorter than the pedicels, J inch acrosa 

 Sepals green, fleshy, linear, rather acute. Petals 4 times the sepals, ovate-lanceo- 

 late, acute, wide spreading, pinkish white. Stamens spreading, shorter than 

 the petals, filaments white, anthers purple. Scales white, longer than broad. 

 Carpels white, erect, equalling the stamens, erect in fruit ; styles pink. 



Flowers July-August. Hardy. 



Habitat. — North China. 



A pretty plant, not in cultivation, so far as I am aware, until 1913, 

 when Mr. F. N. Meyer, of the American Legation at Pekin, sent to 

 Kew specimens collected by him at 3,000 metres at Hsiao Wutai 

 Shan, Chihli, China. Named after Alexander Tatarinow, author of 

 a catalogue of Chinese drugs (1856).

A well known and distinct garden plant, abnormal in the Telephium 

 section in its creeping habit and the presence of barren shoots. Its 

 long, sinuous, bare, decumbent stems, entire rounded leaves, and dense 

 heads of dull purple flowers, sufficiently distinguish it. 



It occurs in two forms: — (a) typica, with orbicular to obovate 

 glaucous leaves about | inch long by f inch broad and prostrate habit ; 

 and (6) majus mihi, of stronger, more erect growth with longer greener 

 leaves (up to ij inch long by ^ inch broad) and larger inflorescence. 



Description. — A procumbent glaucous semi-evergreen perennial. Stems 

 long, procumbent, occasionally rooting, sinuous, bare below, smooth, round, 

 ascending and leafy above, the flowering shoots about 6 inches high. Leaves 

 of barren shoots alternate, sessile, flat, comparatively thin, entire, obovate to 

 orbicular, rounded above, sometimes slightly retuse or apiculate, ^-i inch long 

 by i-J inch broad, tapered below ; those of the flowering shoots larger, ovate, 

 cordate, with a small flat spur. Inflorescence cymose, very dense, surface convex. 

 Buds ovate, blunt, plum-colour. Flowers not opening widely, i inch across, dull 

 purple, shorter than the pedicels. Sepals lanceolate, blunt, glaucous, separate 

 nearly to the base. Petals purple on face, glaucous-purple on back, ovate- 

 lanceolate, blunt, T^ inch long, | longer than the sepals. Stamens equalling the 

 petals, filaments purple, anthers yellow or purplish. Scales spathulate, thrice 

 as long as broad. Carpels erect, equalling the stamens, styles short.
