132 ON SOME MOUNTAIN PLANTS FEOM NOBTnEKN CHINA. 



the Lam-tai-wu mountain, near Amoy. It has glandularly pubescent 

 foliage and flowers, the latter solitary or 2-3 together from lateral 

 scaly buds, and borne on peduncles nearly twice as long as them- 

 selves ; the calyx tube is conoideo-campanulate, with oblong reflexed 

 sec^ments glandularly toothed, nearly equalling the tube, the petals 

 conspicuous, oblong-orbicular, the ovary smooth and elongated, tipped 

 with a very long style ; the leaves are short-stalked, oblong, acute, 

 with a thickened glandular margin and fine serratures. This is very 

 likely P. humiUs, briefly described in Bunge's Enum. pi. Chin. bor. ; 

 if not, it is apparently new. jS'otwithstanding the shorter calyx tube, 

 I think the affinity of this species is certainly with the small group 

 desio-nated Microcerasus by P. B. Webb and Spach ; its habit is entirely 

 that of P. prostrata, Labill. (including P. iiicana^ Stev., and Cerasus 

 pectinata, Spach), P. microcarpa, C. A. M., and Cerasus incisa, Boiss., 

 as far as can be judged by herbarium specimens. 



Rulus {suffruticosi, corcliorifolii) cratmgifolius^ Bge. 

 PirxLS {Malus) haccata, Linn. 



PiErs {Sorhus) pohuashanensis, sp. nov. — Frutescens, gemmis 

 lanatis, foliis parvis 6-7 jugis, foliolis parum inaequalibus apicalibus 

 paulo minoribus e basi oblique rotundata ovato-lanceolatis acuminatis 

 argute serratis supra ad nervos sparsim hirtellis subtus flavido-cinereis 

 venisque saturatioribus reticulatis cum petiolo dense tomentosis, 

 stipulis subdimidiato orbibulatis inciso- serratis foliolis multo minori- 

 bus, corymbis dense multifloris, peduncuKs villoso-tomentosis demum 

 glabratis, floribus bracteolis linearibus scariosis stipatis, calyce tomen- 

 tello, pomo ovali 7 millim. longo (ex sicco sordide aurantiaco), calycis 

 baud immersi dentibus rigidis conniventibus, disco dense hirsute. IsTear 

 the top of the mountain. 



Approaches nearer to P. Aticuparia, Gaertn. (Britannia! Gallia!) 

 and P. gracilis, S. and Z. (Japonia, Maxim. !) than to P. samhucifolia, 

 Cham, and Schlecht. (Sachalin, Glehn !) Though not nearly so large, 

 the stipules are not unlike those of the Japanese shrub. It appears 

 quite distinct, and is a most interesting discovery. 



Oresitrophe rupifraga, Bge. " Fleurs roses. Crott sur les rochers 

 nus. Pas de feuilles." 



Deutzia grandiflora, Bge. (Maxim. Revis. Hydrang. As. orient. 

 t. iii., fl". 1—13.) 



Deutzia parviflora^ Bge. (Maxim. Rev. Hydr. As. or. t. iii., ff. 

 18—32.) 



Riles {Grossularia) wacrocalyx, Hance. This seems more nearly 

 allied to some of the Noith American than to any North-East Asiatic 

 Bpecies. 



Riles {Rilesia, nigra') nigrum, Linn. This seems to agree very 

 well with a Dahurian example of Turczaninow's R. paucijiorum, 

 gathered by him in 1833 ; but in Dr. Bretschneider's specimen the 

 leaves, which are very young, have the petioles and principal nerves 

 beneath pretty thickly clothed with white paleaceous hairs usually 

 tipped with an orange-coloured gland, and the glandular dots are less 

 numerous than usual. 



Alelia Davidii, Hance. Flowering specimens now received enable 

 me to complete my original imperfect diagnosis. (Seem. Journ. Bot., 

 vi., 329.) Foliis nunc irregulariter pauci-inciso-serratis, floribus
