RHAMNACEAE. — PALIURUS 211 



Folifi plerumque 5-10 cm. longa, apice siibito in acumen 3-5 mm. longum 

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



5. P. tonkinensis. 

 Fructus ala angusta plerumque trilobata cinctus, tomentosus. 



6. F. ramosissimus. 



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. tonkinensis, 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 

 mm. longi, pubescentes. Inflorescentia axillaris, cymoso-paniculata, vix ad 

 1 cm. longa, pilosa; flores flavescentes, circiter 5 mm. diam.; pedicelli fructiferi 

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

 quilonga. Fructus maturus rubro-brunneus, glaber, supra planus, ala 6-8 mm. lata 

 inclusa 1.5-2.3 cm. latus, 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 

 convexa. 



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

 or tree 4.75 m. tall, yellow flowers; No. 9427^; trees 2.5-5 m. tall, greenish-yellow 

 flowers) . 



Possibly this species is the true P. australis, 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.

Franchet, PI. David. 71 (1884), cites a specimen collected by David in southern 

 Schcnsi under this name. I have not yet seen it, but I do not believe that the 

 true P. Spina-Christi occurs in China.
