Determined by Alfred Rehder and E. H. Wilson. 

 SABIA Colebr. 



Sabia Ritchieae Rehder & Wilson, n. sp. 



Frutex scandens, 2-metralis; ramuli annotini glabri v. initio 

 sparse puberuli, hornotini luteo-virides, fuscescentes, vetustiores 

 obscure fusci; gemmae perulis ovatis acuminatis glabris minute 

 ciliolatis. Folia decidua (nondum plane evoluta), elliptico-ovata v. 

 oblongo-elliptica, acuminata, basi late cuneata, margine scariosa 

 initio minute ciliolata, supra initio ad costam sparse puberula, cete- 

 rum glabra. Flores subpraecoces, axillares, solitarii, obscure pur- 

 purei, penduli; pedicelli 1.2-1.5 cm. longi, puberuli; sepala minuta, 

 vix 1 mm. longa,semiorbicularia, glabra; petala erecta, caduca, obovata, 

 apice rotundata, circiter 7 mm. longa; stamina petalis paullo breviora 

 filamentis complanatis glabris, antheris ovoideis introrsis; discus 

 annularis, glaber; pistillum petala aequans, glabrum, stigmate simplice. 



Western Hupeh: Hsing-shan Hsien, mountain-sides and grass- 

 clad places, alt. 1000-1200 m.. May 1907 (No. 2533). 



This new species is closely related to S. leptandra Hooker f . & Thomson which 

 has purplish green flowers with exserted stamens and beautifully reticulated leaves. 

 It must also be closely related to S. Cavaleriei Leveill^, which we have not seen 

 but which is described with oblong leaves, tomentulose peduncles and yellow 

 petals. 



Henry's No. 6780 from Hupeh probably belongs here. The specimen is in ripe 

 fruit and has sub-coriaceous, elliptic to elliptic-oblong, abruptly acuminate leaves 

 broadly cuneate at the base, glabrous and dark green above, pale below, 5-8 

 cm. long and 2.3-4 cm. broad, the primary and secondary veins and the veinlets 

 prominent on the under surface. 



Sabia Ritchieae is named for the wife of Mr. W. W. Ritchie, Postal commis- 

 sioner at Chengtu in 1910, in appreciation of kindly services to me during the 

 autumn of that year. E. H. W. 



Sabia latifolia Rehder & Wilson, n. sp. 



Frutex scandens, 2-3-metralis; ramuli hornotini sparse villosi, 

 annotini glabri, luteo-virides, rarius purpurascentes, vetustiores lenti-
