yunnanensis, but in that species the leaves are much paler, rather whitish beneath, 

 and the inflorescence is finely pilose. S. verrucosa and S. yunnanensis reqmre 

 further study. 



S3Tinga tetanoloba Schneider, n. sp. 



Frutex ad 4-metralis; ramuli juniores glaberrimi, fusco-brunnei, 

 lenticellis minimis flavis sparse obtecti; gemmae glabrae, perulis 

 breviter acuminatis. Folia ramorum floriferorum e basi subacuta lan- 

 ceolata, apicem versus acuta v. subacuminata, circiter 8-9 cm. longa, 

 3-3.5 cm. lata, supra viridia, glabra, costa media incisa, subtus pallidiora, 

 basin versus ad costam barbata, margine minute ciliato-denticulata 

 scabra; petioli 10-14 mm. longi, tantum supra pilosi. Inflorescentiae 

 juniores (evolutas non vidi) fere glaberrimae, purpurascentes; flores 

 albo violacei?; pedicelli 1-2 mm. longi, plerumque glaberrimi; calyx 

 circiter 2 mm. longus, glaberrimus, margine truncatus v. subdenticu- 

 latus; tubus corollae 8-9 (-10) mm. longus, laciniae 3-6 mm. longae, 

 angusto-lanceolatae, obtusiusculae, post anthesin explanatae (an 

 reflexae?). Fructus ignotus. 



Western Szech'uan: toward Sungpan, thickets, alt. 3600-4000 

 m., August 1910 (No. 4569). 



Though the specimen is rather meagre, this form can be readily distinguished 

 from S. Sweginzowii Koeline & Lingelsheim and from all the other species of this 

 group by the extremely long lobes of the corolla. 



Syringa Rehderiana Schneider, n. sp. 



Frutex ad 6-metralis ut videtur robustus; ramuli juniores vetustiores- 

 que dense cano-tomentelli. Folia ramorum sterilium e basi rotundata 

 late elliptica,apice breviter acuta v. subacuminata, supra intense viridia, 

 laxe puberula, subtus cinerea, distinctius sed baud dense pubescentia, 

 praesertim ad nervos barbata, margine ciliata, 8-10 cm. longa, 3.5-5 

 cm. lata, ramulorum floriferum ut videtur plus minus lanceolata; 

 petioli breves, 6-10 mm. longi, hirsuti. Inflorescentia magna, ad 

 17 cm. longa et 14 cm. lata, cano-tomentella v. breve hirsuta; flores 

 albi; pedicelli subhirsuti, calycibus tantum infra mediam pilosis mar- 

 gine truncatis vix denticulatis 1-1.5 mm. longis breviores; tubus 

 corollae circiter 10 mm. longus, apicem versus vix dilatatus; laciniae 

 corollae post anthesin explanatae et reflexae, circa 2 mm. longae, ovato- 

 obtusae; antherae superiori parte tubi insertae, sed faucem corollae 

 baud attingentes. Fructus ignotus.
