ARALIACEAE. — ACANTHOPANAX 561 



V. lanceolata v. oblongo-oblanceolata (lateralia saepe obliqua et leviter 

 curvata), basin versus angustata et interdum subpetiolulata, apice 

 acuta V. acuminata, margine praeter basin subintegram crenulato- 

 serrulata, glabra, subtus paullo pallidiora, circiter 2-5 cm. longa, 0.5-1.6 

 cm. lata. Umbella in ramulo abbreviate v. elongate terminalis soli- 

 taria, pedunculata pedunculo glabro 2-4 cm. longo v. interdum brevis- 

 simo, pedicellis glabris 5-10 nam. longis; styli 3-5, basi breviter con- 

 nati. Fructus subglobosus, in sicco angulatus, 6-7 imii. diam., niger. 

 Western Szech'uan: ascent of Pan-lan-shan, west of Kuan 

 Hsien, cliffs, alt. 2400-2700 m., June and August 1908 (No. 1972, tyipe); 

 northeast of Sungpan Ting, thickets, alt. 2400 m., August 1910 (No. 

 4561); Tachien-lu, May 1904 (Veitch Exped. No. 3690). 



This species is closely related to A. pentaphyllus Marchal, but is easily dis- 

 tinguished from it by the terminal inflorescence, by the styles being connate only 

 at the base, by the narrower leaflets and by the bristle-like prickles. 



Acanthopanax Rehderianus Harms, n. sp. 



Frutex scandens circiter 3-metralis; ramis satis tenuibus, junioribus 

 minute puberulis cinereis v. flavido-cinereis; aculeis infrastipularibus 

 solitariis v. geminis v. paucis dissitis longe decurrentibus validiusculis 

 recurvis v. fere rectis minute puberulis 0.3-0.5 cm. longis. Folia longe 

 petiolata petiolis 2-7 cm. longis; foliola 5, rarius 3-4, subsessilia, 

 obovata v. obovato-oblonga v. oblanceolata, acuta v. breviter acu- 

 minata, basi sensim attenuata, triente v. interdum dimidio inferiore 

 excepto crenato-serrulata dentibus leviter incurvis, 2-6 cm. longa et 

 0.8-2 cm. lata, glabra, supra lucida, subtus vix pallidiora, nervis in- 

 conspicuis costa media tantum leviter elevata. Umbella in ramulis 

 abbreviatis v. elongatis terminalis, solitaria, pedunculata pedunculo 

 glabro 1-2 cm. longo; pedicellis glabris circiter 1 cm. longis gracilibus 

 interdum 1 v. pluribus ad basin pedunculi evolutis; styli 4-5 breves 

 connati, apice in stigmata 4-5 brevissima patentia v. recurva divisi. 

 Fructus subglobosus, in sicco angulatus, 5 mm. longus, niger. 



Eastern Szech'uan : Wushan Hsien, alt. 1200 m., September 1907 

 (No. 1974, type). Western Hupeh: without precise locality, .4. 

 Henry (No. 5930); without precise locaUty, June 1901 (Veitch Exped. 

 No. 1020). 



This species is most closely related to A. Wilsonii Harms, but the stouter soli- 

 tary infrastipular prickles, the broader leaflets with more crenate serration, the 

 shorter peduncles and the connate styles distinguish it at once. From A. penta- 

 phyllus Marchal with which it agrees in its prickles and in the connate styles it 

 difl'ers chiefly in its terminal short-stalked inflorescence.
