1923| SCHNEIDER, NOTES ON HYBRID BERBERIS 215 



scentiae racemosae, ad 5.5 (vel 7) cm. longae, pedunculo nudo 1-2 cm. 

 longo incluso, satis laxiflorae, cum ramulis pendentes; pedicelli graciles, 

 infimi ad 10, superiores 5-7 mm. longi, bracteis anguste lanceolatis acu- 

 minatis circiter 2 mm. longis suffulti; flores lutei (?), aperti circiter 7 mm. 

 diametientes (?); sepala externa prophylliformia ovato-lanceolata, media 

 ovato-elliptica vel elliptico-oblonga illis fere duplo majora, interna obo- 

 vata vel obovato-oblonga, satis angusta, 3.5-4 mm. longa; petala obovato- 

 elliptica, 4-4.5 mm. longa, apice breviter inciso-emarginata, basi vix vel 

 distinctius subunguiculata, glandulis 2 aureis oblongis separatis medio- 



cribus praedita; stamina petalis % breviora, apice truncata; ovarium 



elliptico-oblongum, stigmate satis crasso sessili, ovulis 2 sessilibus. Fructus 



elliptico-oblongi, ad 11 : 4-5 mm. magni, ut videtur pallide vel atro- 

 sanguinei, interdum paullo pruinosi; semen 1, ad 7 mm. longum, atro- 

 purpureum, minutissime punctulatum. 



This variety comes very near the typical B. laxiflora but looks rather 

 different at first sight with its mostly much narrower leaves which have a 

 richer and closer serration. Apart from this serration and the yellow- 

 grayish color of the young twigs one might take it for B. chinensis. As 

 the type I regard specimens from the Harvard Botanical Garden collected 

 on May 27, 1880 (flowers) and October, 1879 (fruits), and preserved in 

 the Herbarium of the Arnold Arboretum. Plants cultivated in that 

 Arboretum in 1903, of which flowers have been collected by Rehder on 

 May 22, agree well with the type. A plant from the Kew Arboretum, 

 collected in October, 1906 (as B. sinensis no. 2), seems also to belong to this 

 variety. 



X B. laxiflora var. Langeana, var. no v. 



Frutex erectus, ut videtur habitu B. vulgaris, ramis satis crassis, ramulis 

 ut videtur pendentibus, ad ultra 1.5 m. altus; ramuli annotini distincte 

 purpureo-brunnescentes, sulcato-angulati, etiam biennes brunnescenti- 

 cinerei, deinde cinerascentes vel vetustiores nigrescentes, internodia 1.5-3 

 cm. longa; spinae summis exceptis satis validae, simplices vel 3-fidae, 

 brunnescentes vel flavo-brunnescentes, subtus sulcatae, mediae 1-3.5 cm. 

 longae, latioribus angulo recto patentibus vix longiores. Folia ad 8- 

 fasciculata, valde inaequalia, matura crasse papyracea, ramulorum fer- 

 tilium obovato-oblonga vel obovato-elliptica, apice satis obtusa, basi 

 cuneato satis subito in petiolum 3-12 mm. longum attenuata, margine 

 integra vel parce et subtiliter serrata, rarius (majora inferiora) distincte 

 et satis anguste serrulata, minimis exceptis 2-6 cm. petiolo incluso longa 

 et 0.8-2.5 cm. lata, superne intense viridia, subtus pallidiora, leviter 

 glaucescentia, pruinosa, utrinque paullo laxius quam in B. vvlgari reticu- 

 lata (margines cellularum epidermidis paginae superioris subrectae, in- 

 f erioris paullo undulatae) ; ea ramulos novellos f ulcientia majoribus alteris 

 similia vel majora et distinctius serrato-dentata, surculorum ovato- 

 elliptica, acutiora, subito in petiolum brevem contracta, pleraque distincte
