(not ovate, acuminate, widest one-third way up), and scales with the 

 limb twice as broad as long (not as broad as long). 



S. Esquirolii Leveille and S. viscosum Praeger are hairy plants 

 with long-stalked leaves and flowers. 



Sedum triphyllum, sp. nov. Species sinensis sectionis Japonicce 

 Maximowicz, ramis sterilibus longis, ramis floriferis brevibus, foliis 

 oblongo-oblanceolatis obtusis, inflorescentia cymosa densa pei-foliosa, 

 sepalis spathvilatis vel lineari-spathulatis, squamis planis, ab speciebus 

 aliis ternato-foliatis sectionis ejus distinguenda. 



Herba glabra pei-ennis senipervirens, late repens, e nodis radices 

 copiose emittens. Rami steriles 15-22 cm. longi, foliosi, apicibus 

 adscendentibus. Bami floriferi ramis sterilibus similes sed breviores 

 vel baud altiores, simplices, foliosi, in parte superiore dense mammil- 

 lati. Folia ramoinim sterilium ternata, internodia jequantia vel 

 superantia, integra, oblongo-oblanceolata, infra attenuata, subpetiolata, 

 ajiice rotundata, plana, subcarnosa, marginibus mammillatis, pulchre 

 viridia, subtus pallida, 15-20 mm. longa, 4 mm. lata, parte inferiore 

 erecta, jmrte superiore patentia ; calcar obtusum, plerumque deltoideuni, 

 noniunujuam bitidum ; ramorum floriferorum folia eis ramorum steri- 

 lium similia, superiora sa?pe alterna. Injiorescentia terminalis, per- 

 foliosa, densa, plana, 3-5 cm. diametro, e ramis dichotomis tribus 

 composita, flore infimo breviter pedicellato, floribus reliquis subses- 

 silibus vel sessilibus ; bracteae coarctatse, amplje, foliis similes, calcaratae, 

 marginibus mammillatis. Flores lutei, 16 mm. diametro. Sepala 

 injequalia, obtusissima, fere ad imum libera, obtuse calcarata, majora 

 s])athulata, 7 mm. longa, minora spathulato-linearia, 4 mm. longa. 

 Petala lineari-lanceolata, acutiuscula, 9 mm. longa, 2 mm. lata, 

 apicibus cucullatis. Stamina 10, petalis paullo breviora, 8 mm. longa, 

 epipetalina infra medium petalorum inserta, antheris aureo-rubris. 

 Squamce parvai, quadrate, aureae. Carpella gracilia, erecta, virides- 

 centi-lutea, 7 mm. longa, stylis gracilibus. 



ILih. Yunnan. Raised from seed collected by Rev. E. E. Maire, 

 on "rocheis a mi-mont, altitude 2990 metres," near Tong-tchouan, 

 in 19ir, Flowered at Glasnevin and in my own garden in August, 

 1917. 



Related to S. sarmentosum Bunge, S. lineare Thunb., and 

 S. Chattveaudi R. Hamet, all of which have also ternate leaves. 

 From the two first it may be distinguished by its blunt leaves broadest 

 near the apex, its copious axillary rootlets, its dense, very leafy inflor- 

 escence, and blunt broad-tipped sepals. It comes near aS'. Chauveaudi, 

 but that plant has tall (12-18 cm.) erect flowering shoots (not short, 

 ascending), short (3-6 cm.) barren shoots (not long, 18-22 cm.) 

 smaller leaves, those of barren shoots about 10x3 mm., of fertile 

 shoots about 9x3*5 mm. (not all similar and about 15-20x4 mm.). 

 In >S'. triphj/IIum, moreover, the flower-stems are densely mammillate 

 (a character not mentioned in Hamet's full description of Chau- 

 veaiidi), and the scales are flat (not subterete).
