214 JOURNAL OF THE ARNOLD ARBORETUM [vol. iv 



5-5.5 mm. longa, obovata, apice leviter emarginata vel subretusa, basi 

 paullo attenuata, glandulis 2 satis magnis ovoideo-oblongis aurantiacis 

 separatis praedita; stamina normalia ut in B. vulgari; ovarium oblongo- 

 ellipticum, stigmate satis lato sessili, ovulis 2 subsessilibus. Fructus 

 oblongo-elliptici, circiter 10 : 5 mm. magni stigmate sessili excluso, ex cL 

 Schrader initio pallide sanguinei, deinde saturate sanguinei vel coccinei; 



semina?. 



Schrader's type is a very uncertain form supposed to have come from 



America. I first thought it might be nothing but B. vulgaris brought back 



from America because it has no connection whatever with B. canadensis. 



At present I am inclined to consider B. laxiflora a cross between B. chinensis 



and some form of B. vulgaris. The long racemes bear some resemblance 



to those of B. amarensis as I said in 1907 but this species had not yet been 



introduced at Schrader's time. Later B. laxiflora mostly has been taken 



for B. vulgaris but there are so many forms in cultivation under the name 



B. laxiflora that it is impossible to decide which form a certain author 



may have had in mind. It is not without some hesitation that I propose 



to keep Schrader 's name for what I regard as a cross between B. chinensis 



and B. vulgaris. There seem to be in gardens also some rather different 



forms of this origin which may be distinguished as follows: 



Hamuli annotini flavo-cinerei vel cinereo-brunnescentes (non satis brunnescentes 



vel violascentes). 

 Folia ramulorum floriferorum anguste obovato-oblonga, circiter 10-20 mm. lata, 



subobtusa, satis parce vel indistincte serrato-denticulata vel subintegerrima. 



var. typica. 



Folia ramulorum floriferorum oblanceolata, 6-15 mm. lata, acutiora, satis dense 



breviter serrulata var. oblanceolata. 



Hamuli annotini satis distincte purpureo-brunnei, etiam biennes brunnescenti- 

 cineraacentes; folia ramulorum floriferorum obovato-oblonga vel obovato- 

 elliptica, breviter vel grossius satis distanter serrato-dentata var. Langcana. 



X Berberis laxiflora var. oblanceolata, var. no v. 



Frutex ad ultra 1 m. altus, habitu ut videtur B. chinensis ramis elongatis, 

 ramulis plus minusve dependentibus ; ramuli annotini flavo-cinerei vel 

 cinereo-brunnescentes, sulcato-angulati, biennes cinerascentes ; internodia 

 1.5-2.5 cm. longa; spinae satis debiles, simplices vel inferiores 3-fidae 

 (surculorum non visae), leviter brunnescentes, subtus vix vel paullo sul- 

 cata*, mediae ad 8 mm. longae. Folia ad 8-fasciculata, matura papyracea, 

 ramulorum fertilium oblanceolata, apice acuta vel subacuta, basi sensim 

 in petiolum vix ad 5 mm. longum attenuata, margine distincte serrulata 

 dentibus utrinque 8-15 minimis vel ad 0.75 mm. longis, 2-4 cm. longa et 

 0.6-1.3 cm. lata, superne viridia, subtus paullo discoloria, (vel subciner- 

 ascentia?), utraque facie satis anguste vel superne laxius reticulata 

 (margines cellularum epidermidis utrinque aequimagnarum distincte 

 undulatae) ; ea ramulos juveniles fulcientia vel surculorum ut videtur ma- 

 joribus simillima (vel in formis similibus folia surculorum latiora), elliptica, 

 vel ovato-elliptica, obtusiora, minus dense vel vix serrata, basi subito in 

 petiolum brevem contracta, 3-5 cm. longa et 1.3-2 cm. lata. Inflore-
