1923] SCHNEIDER, NOTES ON HYBRID BERBERIS 199 



Berberis hauniensis, nov. spec, vel hybr. 



Frutex ut videtur satis dense subelongato-ramosus; ramuli annotini, 

 flavo-rubri vel ut biennes sordide rubro-brunnei, distincte angulato-sulcati, 

 lenticellosi sed satis laeves, vetustiores nigro-cinerascentes; internodia 1-2 

 cm. longa; spinae simplices, patentes, brunnescentes, 1-2 cm. longae, 

 subtus sulcatae vel 3-fidae et laterales mediis breviores. 



Folia ad 8-fasciculata, inaequalia, matura tenuiter chartacea vel char- 

 tacea, ramulorum fertilium obovato-oblonga vel anguste oblonga, apice 

 fere semper obtusa vel rotundata, basim versus subito in petiolum ad 

 5 mm. longum attenuata, margine integerrima vel satis minute serrulata, 

 dentibus gracilibus utrinque 4-5 vix 1 mm. longis, superne intense viridia, 

 subtus discoloria et pruinosa, utraque pagina laxe tenuiter elevato-re- 

 ticulata (margines cellularum epidermidis utriusque faciei aequimagnarum 

 rectae vel subrectae), minimis exceptis 2-4 cm. longa et 0.9-1.7 cm. lata; 

 folia ramulos novellos fulcientia saepe oblongiora, acutiora, grossius 

 serrata, ad 5.5 : 2 cm. magna petiolis ad 1 cm. longis inclusis, surculorum 

 majora, obovato-oblonga vel obovato-elliptica, saepissime densius brevi- 

 serrata, ad 6 : 2.5 cm. petiolis inclusis magna. Inflorescentiae inferiores 

 distincte paniculato-racemosae, superiores racemosae, omnes densiflorae, 

 10-20-florae, nutantes, 2-3.5 cm. longae, rubescentes, axis satis tenuibus; 

 pedicelli graciles 4-6 mm. longi basi bracteis anguste lanceolatis acuminatis 

 2-3 mm. longis suffulti; flores ut videtur aurei et extus paullo rubescentes, 

 aperti circiter 8 mm. diametientes; sepala externa triangulari-lanceolata, 

 mediis elliptico-oblongis minora, interna circiter 5 mm. longa, obovata; 

 petala circiter 6 mm. longa, satis anguste elliptica, apice distincte inciso- 

 emarginata, basi vix contracta, glandulis 2 distantibus aurantiacis satis 

 parvis oblongis separatis praedita; stamina petalis fere duplo breviora, 

 apice vix vel brevissime apiculata; ovarium elliptico-oblongum stylo 

 nullo vel indistincto, stigmate mediocri, ovulis 2(-l) subsessilibus. Fruc- 

 tus ut videtur elliptici, ? cerasini, circiter 10 mm. longi et 5 mm. crassi, 

 estylares vel stylo brevissimo coronati; semen fere semper 1, cinnamomeum, 

 levissime punctulatum, circiter 6 mm. longum. 



This is another striking form of very uncertain origin. I received 

 from the Botanical Garden at Copenhagen flowering specimens of June 

 10th and fruiting specimens of October, 1916, under the name B. cretica. 

 The lower parts of the dense inflorescence is distinctly paniculate and, so

Willd. The texture and dentation of the leaves is not unlike those of 

 B. aristata DC. The fruit sometimes shows a short distinct style but I 

 have never found more than two ovules. The somewhat paniculate 

 inflorescence seems to indicate an influence of B. ckitria Hamilt., while

incialis. The spines resemble those of B. aristata or 

 B. chitria. The bracts are relatively long and acuminate as in B. chinen- 

 sis Poir. There are no stomata on the upper surface of the leaves, and 

 nothing indicates that B. cretica may be one of the parents.
