RHAMNACEAE. — PALIURUS 211 



Folia pleriimque 5-10 cm. longa, apice sublto in acumen 3-5 mm. longum 

 producta; alae fructuum ut videtur satis crassae, vix 5 mm. latae.

 Fructus ala angusta plerumque trilobata einctus, tomentosus.

ENUMERATIO SPECIERUM. 



1. Paliurus orientalis Hemsley. See p. 209. 



2. Paliurus hirsutus Hemsley in Kew Bull Misc. Inform. 1894, 388. 

 Kwangtung: C. Ford (No. 280, type). 



According to the descriptions of Hemsley and Pitard this species may be closely 

 related to P. tonkinensisj but without having seen ripe fruits of P. hirsutus I can- 

 not decide if the two species are the same. 



3. Paliurus sinicus Schneider, n. sp. 



Arbor spinosa, ad 5-metralis; ramuli hornotini pubescentes, deinde nigricantes, 

 glabri v. tantum supra gemmas puberuli; spinae in speciminibus visis rarae, parvae, 

 vix 5 mm. longae. Folia membranacea, ovata, interdum ovato-oblonga, basi 

 obtusa^ V. rotunda, sed semper subito brevissime in petiolum producta, obliqua, 

 apice in acumen 5-12 mm. longum attenuata, margine crenato-dentata, supra 

 viridia, glabra v. tantum initio ad nervos primarios tres parce pilosa, subtus 

 paullo pallidiora, tota facie puberula v. fere glabra, nervis primariis et secundariis 

 satis prominentibus, 2.5-7 cm. longa, 1.5-4 cm. lata; petioli breves, tantum 2-4 

 nam. longi, pubescentes. Inflorescentia axillaris, cymoso-panlculata, vix ad 

 1 cm. longa, pilosa; fiores flavescentes, circiter 5 mm. diam,; pedicelli fiuctiferi 

 10-12 mm. longi; sepala triangularia, acuta, petalis pro genere normalibus subae- 

 quilonga. Fructus maturus rubro-brunneus, glaber, supra planus, ala 6-S mm. lata 

 mclusa 1.5-2.3 cm.latu8,sine ala ad 5 mm.altus et 9 mm.latus; semina levia, oliva- 

 ceo-brunnea, fere orbicularia, 2-2.5 mm. lata, ventre applanata, dorso leviter

Yunnan : Mengtze, alt. 1800 m., woods, A. Henry (No. 9427, type; shrub 1.25 j^^ 

 or tree 4.75 m. tall, yellow flowers; No. 9427**; trees 2,5-5 m. tall, greenish-yeUow 

 flowers). 



Possibly this species is the true P. australiSj var. orientalis Franchet (see P. 

 orientalis) . It is well distinguished from the allied species by its very short petioles. 

 The fruits are smaller than those of P. orientalis Hemsley or of P. Spina-Christi 

 Miller.
