RHAMNACEAE. — RHAMNUS 249 



serrata dentibus incumbentibus callosis, 1-2.2 cm, longa, 0.6-1.5 cm. lata; 

 petioli graciles, superne sulcati, pilosi, 3-6 mm. longi; stipulae pilosae, petiolia 

 subaequilongae v. paullo breviores, plus minusve persistentes. Flores axillares, 

 singuli V. bini, tetrameri, glabri, dioeci, tantum masculos vidi; sepala lanceolata, 

 triangularia, sensim acuminata, receptaculo fere duplo longiora; petala lanceolata, 

 sepalis fere duplo breviora, staminibus sublongiora; ovaria perparva, reducta. 

 Fructus obovato-globosus, circiter 5 mm. crassus; pedicelli glabri, 4-7 mm. longi; 

 semina 2, obovata, laevia, dorso aulco tantum basi aperto instructa. 



Korea: Hallaisan, alt. 1800 m., July 1907, U. Faurie (No. 1890, tj^e; bush 

 1 m. tall); Quelpaert, "in sylvis Yeng sil " (?). alt. 1000 m., August 17, 1908, 

 Taquet (No. 1210); "in sylvis Hallaisan," June 1909, Taquet (No. 30S1). 



This seems to be a dwarf, very branched, alpine species, which may be closely 

 related to R, glohosus Bunge as interpreted above. 



23. Rhamnus Meyeri Schneider, n. sp. 



Frutex, ut videtur valde ramosus, spinosus; ramuli suboppositi, homotini 

 graciles, tenuiter puberuli, flavo-cinerei v. leviter brunnescentes, vetustiores 

 cinerascentes; gemmae parvae, ovato-globosae, squamis paucis rotundatis ciliatis 

 obtectae. Folia opposita, crasse papyracea, decidua, ovata v. ovato-rotunda v. 

 orbicularia, raro ovato-oblonga, basi rotunda v. fere subcordata v. obtusa, rare 

 acuta, apice acuta v. subito breviter-acuminata, supra viridia, opaca, tenuissime 

 sparse pilosa, subtus paullo pallidiora, praesertim ad nervos utrinseeus 2-3 paullo 

 prominulos pilosa et barbata, margine satis dlstincte crenato-dentata, latiora 

 1.5-3 cm. longa, 1-2.5 cm. lata, angustiora ad 3 cm. longa ct 1.3 cm. Iata;_petioli 

 graciles, 3-8 mm. longi, supra sulcati, pilosi. Flores non vidi. Fructus solitarius, 

 globosus, circiter 6:5 mm. crassus, ? niger; semen obovato-oblongum, ollvaceum, 

 dorso sulco lato elongate distincte aperto instructum. 



Shantung: near Lung-Tung, September 28, 1907, F. N. Meyer (No. 249). 



To this species may possibly belong a specimen of the same collector from 

 Shan8i,Tsin-tse,May 5, 1907,(No. 406) with the same thin minutely pubescent spiny 

 branchlets, very young puberulous leaves and male flowers, which may be de- 

 scribed as follows: flores masculi, tctrameri, axillares, 1^-fasciculati, tenuissime 

 puberuli; pedicelU vix ad 3 nmx. longi; sepala late ovata, acuta, receptaculo vix 

 longiora; petala lanceolata, acuta, sepalis duplo breviora, staminibus aequilonga; 

 ovaria valde reducta. Folia valde juvenilia ut videtur lanceolata. 



It seems somewhat doubtful, however, if these two specimens really belong to 

 the same species, certainly No. 249 represents a good species, which may be nearly 

 related to R. globosiis Bunge, though the seeds with their broad furrows are rather 

 different.

Korea : " Syon ouen," 1901, U, Faune (No. 233, type), " Ouen to " (No. 235), 

 "Ouen san," 1901 (No. 236), 1906 (No. 502); without precise locality, "m 

 dumosis," June 1906, U. Faurie (No, 512); Pingyang, September 18, 1908, J.G. 

 Jack (bush 0.25-0.5 m. tall). 



This species seems to be closely related to R. glohosus Bunge, see above, and 

 also to R. parvifolitcs Bunge, see p. 250. 

 The leaves are alternate or subopposite.
