Hub. Yunnan, Haised at Griasnevin in 1916 from seed sent by 

 Rev. E. E. Maire from Tong-Tchouan, 2900 metres, in 1915. The 

 plants flowered, one in October, 1916, and the rest in August, 1917. 

 They died in the autumn of 1917, but 1 think this was probably due 

 to over-flowering rather than to a natural biennial duration of the 

 plant. 



From the other species of Sedum of the large series Joponica 

 which have also relatively broad leaves (ovate or spathulate) and 

 yellow flowers, S. Mairei may be distinguished as follows: — 



*S'. Alfredi Hance has ligulate (not ovate) petals three times (not 

 slightly) longer than the sepals, rotund-truncate (not cordate-stipitate) 

 scales, and carpels connate half way up (not nearly free). 



S. Dugueyi R. Hamet is a minute plant with tiny crowded ovate- 

 deltoid leaves. 



>S'. Q-iajai R. Hamet is a small hairy plant, with leaves only ^ inch 

 long. 



S. Moroti R. Hamet has blunt spurred obovate sepals, oblong- 

 hnear petals, terete scales. 



*S^. Schoenlandi R. Hamet is easily separated b}^ its hairy leaves, 

 racemose inflorescence, and the presence of only five stamens. 



S. Someni R. Hamet has only five stamens, and is described as 

 annual. In some respects it appears to resemble S. Mairei^ but it has 

 sepals entire and very obtuse at the apex (not papillate-margined and 

 apiculate), petals " subsemioblong " subactate, widest above the middle
