CORRECTIONS AND ADDITIONS TO VOLUME I 435 



haud distincte papillosa, utrinque distincte elevato-reticulata. Inflorescen- 

 tiae 1-3-florae, pedunouli nulli v. brevissimi; flores ab iis B. diaphanae vix 

 diversae, petalis paulo angustioribus, ovulis 7-11; pedicelli fructiferi 2-3 cm. 

 longi. Fructus aurantiaci, ut videtur leviter pruinosi, ovato-elliptici, 15-18 mm. 

 longi et 8-10 mm. crassi, apice paulo attenuati (an semper?) et stylo brevissimo 

 coronati; semina matura 3-5. 



Western Szech'uan: near Was-han (No. 930, type; see p. 353); without 

 exact locality (Veitch Exped. No. 3145, in part, flowering specimens; see p. 354). 



On account of the dark-colored branchlets which are bright red on the cultivated 

 specimens this species has to be kept distinct from B. diaphana. Young plants of 

 B. aemulans cannot be distinguished from those of B. Tischleri Schneider, but this 

 species is very distinct in its mostly elongate subracemose inflorescence and in its 

 elongated almost rostrate fruits. 



Berberis diaphana, var. circumserrata (p. 354). This variety differs in several 

 respects from the true B. diaphana Maximo wicz, especially in its ovaries contain- 

 ing only 4 ovules (not 6-12) and in its habit. It seems to represent a good species 

 which inhabits a different geographical area. It may be described as follows: 



Berberis circumserrata Schneider, n. sp. 



Frutex erectus, satis dense ramosus; ramuli homotini annotinique flavescentes, 

 flavo-brunnescentes v. paulo rubescentes, glabri, striato-angulati, vetustiores 

 cinerascentes ; internodia 1.5-3 cm. longa; spinae normales 3-fidae, flavescentes 

 V. brunnescentes, interdum ad 5-fidae v. reductae 1-fidae, dorso sulcatae, mediae 

 Burculorum ad 2.5 cm. longae. Foha ramulorum fertilium ad 5 fasciculata, matura 

 chartacea, obovato-oblonga v. late obovata, apice rotunda v. leviter emarginata, 

 basim versus in petiolum ad 0.5 cm. longum sensim v. subito contracta, 1.5-3.5 cm. 

 longa et 0.5-2. .5 cm. lata, superne intense viridia, subtus albescentia, pruinosa 

 V. in planta vetustiori paUide viridescentia, utrinque distincte satis anguste v. 

 laxius ut in B. diaphana graciliter elevato-reticulata, margine circumcirca dense 

 spinuloso-serrulata, dentibus 0.5-2 mm. longis gracilibus 3-8 pro 5 mm., folia 

 surculorum (juveniUa longe petiolata excepta) majora v. latiora, ovato- v. elliptico- 

 rotunda v. late elUptica v. obovata, minus dense grossius spinuloso-serrata v. 

 etiam fere integra, 1.5 : 1 cm. ad 4 : 3 cm. v. ad 3 : 3 cm. magna, subtus distinctius 

 albescentia, saepe laxius reticulata. Inflorescentiae 1-3 florae, pedunculo ad 2.5 

 cm. longo; flores lutei, circiter 10 mm. diametientes, ab iis B. diaphanae v. B. 

 Tischleri vix diversi, sed staminibus apice vix apiculatis; ovula pleraque 4, inter- 

 dum 3 V. ad 7. Fructus (plantae cultae) anguste elliptici, apice plus minusve ut 

 in B. Tischleri in stylum elongati, flavo-rubri, partim leviter pruinosi, stylo incluso 

 circiter 13-15 mm. longi et 5-6 mm. crassi; semina 1-3, aurantiaca, laevia; pedi- 

 celli 10-17 mm. longi, bracteis acuminatis ad 2-2.5 mm. longis suffulti. 



Shensi: Tai-pei-shan, 1910, W. Purdom (No. 4, tji^e; with flowers); same 

 locality, February 8, 1911, W. Purdom (Seed Nos. 604, 604% 608); young plants in 

 the Arnold Arboretum, fruiting co-type). 



There are also young plants in this Arboretum under No. 182 of Purdom 

 of which a record is wanting. These plants have not yet flowered and may possibly 

 represent a somewhat different form. B. circumserrata seems to be a good species, 

 resembling in its fruits B. Tischleri but in its inflorescences and in its growth much 

 more B. diaphana. It does not form such regular dense bushes as the latter species 

 and it grows much less vigorously than B. Tischleri. 



Berberis yunnanensis (p. 355). This species does not occur in western Szech'uan. 

 The plants mentioned under B. yunnanensis should be referred to B. Tischleri
