1923] SCHNEIDER, NOTES ON HYBRID BERBERIS 201 



p. 94 as a purple-leaved form of B. canadensis. B. Fischeri of Kirchner, 

 Arb. Muse. 135 (1864) came from the nurseries of F. Booth & Sons at 

 Flottbeck, and seems to be the same as plants I have had before me which 

 well agreed with B. macracantha. Kirchner says, "ein ausgebreiteter 

 Strauch mit rutenformigen Zweigen," a description fitting at least one 

 form of our hybrid. Of the same origin seems to be the following variety 

 which I wish to propose. 



Berberis macracantha var. pulchra, nov. var. (vel probab. planta hybrida 



origine di versa). 



Frutex ut videtur satis tenuiter elongato-ramosus; ramuli annotini 

 flavescentes vel sordide cinereo-brunnescentes, rarius distinctius saturate 

 brunnescentes, paullo vel versus apicem distinctius angulati, biennes 

 cinerascentes, teretiusculi, vetustiores cinerei; internodia 2-3.5 cm. 

 longa; spinae pleraeque 3-fidae, divaricatae vel versus apicem ramulorum 

 simplices, flavo-brunneae, teretiusculae, subtus sulcatae, mediae 0.5-2 

 cm. longae, lateralibus longiores. Folia ad 8-fasciculata, inaequalia, 

 matura chartacea, satis crassa, ramulorum fertilium oblanceolata vel 

 anguste obovato-lanceolata vel subspathulata, apice obtusa vel breviter 

 acuta, mucronulata, basi sensim in petiolum subnullum vel ad 5 mm, 

 longum attenuata, margine basi excepta distincte sed graciliter spinuloso- 

 serrata dentibus patentibus 0.5-1 mm. longis utrinque circiter 8-15, 

 superne saturate viridia, subtus pleraque laete viridia, utraque facie 

 satis anguste elevato-reticulata (cellularum margines epidermidis faciei 

 superioris levissime undulatae, inferioris distincte undulatae), minimis 

 exceptis 2 : 0.8 ad 4.5 : 1.6 cm. magna; folia ramulos novellos fulcientia 

 majoribus ramulorum fertilium similia, sed ad 5.5 : 1.8 cm. magna petiolo 

 longiore incluso, surculorum latiora, ovato-elliptica, grossius remote et 

 interdum subsinuato-serrata, apice obtusiora, basi subito in petiolum ad 

 8 mm. longum contracta, ad 5 : 2.5 cm. magna, subtus fere semper distincte 

 pruinosa, laxius reticulata. Inflorescentiae elongato-racemosae, pedunculo 

 ad 2.5 cm. longo incluso ad 4 cm. longae, 5-8-florae, cum ramulis pendentes, 

 rubescentes; pedicelli interdum versus apicem pedunculi subverticillatim 

 aggregati, 5-7 mm. longi, bracteis anguste lanceolatis acuminatis ad 3 mm. 

 longis suffulti; fructiferi apice leviter incrassati; flores ut videtur aurei, 

 aperti circiter 9-10 mm. diametientes ; sepala externa prophylliformia 

 anguste triangularia mediis obovato-ellipticis duplo minora, interna late 

 obovata, mediis fere duplo longiora, ad 7 mm. longa; petala 6.5-7 mm. 

 longa, late elliptica, apice rotundata, Integra, basi paullo contracta, 

 glandulis 2 ovoideis distinctis aurantiacis separatis praedita; stamina 

 petalis }/% breviora, apice truncata vel vix leviter apiculata; ovarium 

 ovatum stylo distincto, stigmate mediocri, ovulis plerisque 3 subsessilibus. 

 Fructus elliptici ut videtur cerasini et pruinosi, 10-11 : 5-6 mm. magni, 

 stylo distincto ad 0.5 mm. longo excluso; semen plerumque 1, purpuras- 

 cens, fere laeve.
