1923] SCHNEIDER, NOTES ON HYBRID BERBERIS 203 



this Berberis is a cross between B. chitria and B. Lycium. To B. chitria 

 point the brownish twigs, the large hardly papillose leaves, the partly- 

 paniculate inflorescence, and the long fruits, while the stiff inflorescence 

 with the long pedicels, the distinctly pruinose and somewhat papillose 

 leaves seem to indicate the influence of B. Lycium. 



X Berberis Spaethii, hybr. nov. 



Frutex squarrosus latus patenter ramosus, ad ultra 3 m. altus; ramuli 

 annotini pallide flavo-brunnei, teretiusculi, laeves, biennes vetustioresque 

 cinerascentes vel nigrescentes; internodia 2-3.5 cm. longa; spinae saepis- 

 sime simplices, flavo-brunneae, teretiusculae, 0.5-2 cm. longae. Folia ad 

 8-fasciculata, inaequalia, matura chartacea, ramulorum fertilium elliptica, 

 ovato-oblonga vel obovata, apice acuta, rarius obtusa, mucronulata, basi 

 cuneata, in petiolum ad 5 mm. longum attenuata, minimis exceptis 3.5 : 

 1.5 ad 6 : 2.3 vel 5:2 cm. magna, margine satis distincte spinuloso- 

 serrata dentibus utrinque 8-15 versus apicem decrescentibus 1-2 mm. 

 longis patentibus, superne satis obscure viridia, subtus pallide viridia vel 

 cinerascentia, pruinosa, utraque pagina laxe elevato-reticulata (margines 

 cellularum epidermidis faciei superioris rectae, inferioris leviter undulatae) ; 

 folia ramulos novellos fulcientia aliis similia, interdum paullo longiora, 

 surculorum late ovata vel elliptica, saepe subintegerrima, obtusiora, ad 

 5.5 : 3 cm. magna. Inflorescentiae paniculato-racemosae vel racemosae, 

 satis densiflorae, ad ultra 6 cm. longae, axi satis crasso; pedicelli 5-8 

 mm. longi, apice leviter incrassati, bracteae novellae floresque juveniles 

 satis evoluti nondum visi. Fructus elliptici, circiter 11:6 mm. magni, 

 initio opaci, dein purpurascentes pruinosi, brevissime stylares; semina 2, 

 circiter 7 mm. longa, atrobrunnea, levissime punctulata. 



This is a very striking hybrid which came to the Arboretum in 1902 

 from the well known nurseries of L. Spath at Berlin-Baumschulenweg, 

 with the name B. angulizans which is nothing but B. canadensis according 

 to the figure by Massias in Hesdorffer's Monatsh. Blumenfreunde (1896) 

 100, tab. col. The plant, however, distributed by Spath under this name 

 represents a hybrid of unknown origin. It flowered in the Arboretum in 

 September 1906, and I collected fruits of the same plant in October, 1916 

 (no. 4578). It needs further observations and seems to represent a 

 remarkable form.
