356 WILSON EXPEDITION TO CHINA 



3200-3800 m., thickets, October 1910 (No. 4134; shrub 2-2.5 m. 

 tall, fruit red, ovoid; a form with larger leaves and inflorescence). 

 Pan-lan-shan, west of Kuan Hsien, alt. 2300-3000 m., June 1908 

 (Nos. 2856, 2859; bush 3 m. tall, flowers yellow); same locality, 

 thickets, alt. 2600-3000 m., October 1910 (No. 4307; bush 2 m. 

 high); Min valley, Mao-chou, alt. 1600 m., October 1908 (No. 1177; 

 bush 1-2 m. tall, fruit coral red). 



The type of this species had been collected by Potanin in northern Szech'uan 

 (ad fl. Nereku, July 26, 1885). Originally I described the leaves as green on both 

 sides, but this is an error. After comparing the type specimen with Wilson's 

 specimens, I think the latter agree very well with B. Tischleri. Not having seen 

 the flowers before, I have given above the more complete description. 



In the nervation of the leaves this species much resembles B. yunnanensis, but 

 in its inflorescence with more numerous and smaller flowers and in the more elon- 

 gated fruits B. Tischleri differs from that species. At first sight our species looks 

 much like B. Silva-Taroucana Schneider as there indicated. 



In the Arnold Arboretum there is a cultivated plant, bearing the nimiber 181, 

 which seems to be nearly allied to B. Tischleri. 



Here may be added the description of a new species of this section based on 

 material not collected during the Arnold Arboretum Expeditions : 



Berberis Ambrozyana Schneider, n. sp. 



Frutex 0.50-1 m. altus, ut videtur dense et graciliter ramosus; ramuli juniores 

 (hornotini nondum vidi) brunnescentes, glabri, leviter angulati, vetustiores 

 cinerascentes; internodia brevia, 0.3-1 cm. longa; spinae 1-3-fidae, graciles, 

 flavescentes, acutae, mediae ad 12 mm. longae, subrotundae. Folia parvula, ad 8 

 fasciculata, lanceolata v. oblanceolata integerrima apice obtusa, minime mucronu- 

 lata, basim versus angustata, sessilia, supra viridia, subtus albo-pruinosa, utrinque, 

 sed superne distinctius, reticulata, ramulorum floriferorum 8:1.5 ad 12:4 mm. 

 magna. Flores singuli, satis magni, lutei; pedicelli 2-3 mm. longi, basi bracteia 

 rubescentibus circumdati; prophylla et sepala externa non vidi; sepala interna 

 eximie lanceolata, acuta, fere ad 9 mm. longa; petala sepalis minora, anguste 

 oblanceolata, apice bifida, basi vix unguiculata, glandulis 2 oblongis instructa; 

 stamina apice distincte apiculata; ovaria stylosa, ovulis 5 (an semper?) sessilibus 

 instructa. Fructus ignoti. 



Western Szech'uan: without locaUty, alt. 3200-3400 m., June 1904 (Veitch 

 Exped. No. 3146"; shrub 0.5-1 m. tall). 



In the leaves this species closely resembles B. minutiflora Schneider, III. 

 Handb. Laubholzk. II. 914 {B. brevipes (Franchet) Schneider, non Greene), 

 but this Yunnan plant has much smaller flowers; the leaves have a different 

 nervation and the fruits bear a sessile stigma. Berberis Ambrozyana may be more 

 nearly related to Berberis parvifolia Sprague, in Kew Bull. Misc. Inform. 1908, 

 445, which differs from it in its puberulous branchlets and in the smaller and more 

 numerous flowers. I have not yet seen the type of Sprague's species (Wilson No. 

 3154*). In the form of the sepals and petals Berberis Ambrozyana resembles the 

 well-known Japanese Berberis Thunbergii. 



The specific name is in honor of Baron Istvdn Ambr6zy, the Hungarian patron 

 of botany and garden making, to whom I am indebted for much assistance.
