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 number 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 bracteis 
rubescentibus cireumdati; 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 locality, alt. 3200-3400 m., June 1904 (Veitch 
Exped. No. 31465; shrub 0.5-1 m. tall). 
In the leaves this species closely resembles B. minutiflora Schneider, Ill. 
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 István Ambrózy, the Hungarian patron 
of botany and garden making, to whom I am indebted for much assistance.
