BERBERIDACEAE. — BERBERIS 365 



(levissime verruculosi), vetustiores cinerascentes; spinae 3-fidae, gracilcs, supcrne 

 deficientes, mediae ad 3 cm. longae, flavescentes. Folia satis tonuiter coriacea, 

 ovata V. oblongo-ovata, utrinque acuta, basi in petiolum ad 6 mm. longum con- 

 tracta, supra viridia, nitentia, hypodermate non instructs., .^lubtus fore concoloria, 

 utroque latere, sed subtus distinctius laxe reticulata, 3.3:1 cm. ad 5.5:1.8 cm. 

 magna, margine spinoso-dentata dentibus 1-1.5 mm. longis utrinque 7-11 in- 

 structa. Flores 3-15-fasciculati, mediocres, flavi; pedicelli 0.7-2 cm. longi; pro- 

 phylla late-triangularia, sepala interna late-ovata; petala obovato-oblonga, 

 glandulifera; ovaria ovulis 3 instructa. Fructus ovati nigri?, circiter 9:6 cm. 

 magni, stigmatibus sessilibus coronati; semina 2-3. 



Yunnan: Fang-yang-tchong, woods, October 14, 1887, Delavay (fruiting 

 branches; fruits 1-3, fascicled, pedicels up to 2 cm. long); Houang-li-pin supra 

 Tapintze, woods, alt. 1800 m., March 21, 1887, Delavay (type; shrub 1-1.5 m. tall, 

 flowers 8-15, pedicels shorter); Maen-shan, woods, alt. 2500 m., October 22, 1889, 

 Delavay; Chi-tcho-tze, Houan-li-pin, March 12, 1883, Delavay (No. 485). 



To this species may belong, possibly, Wilson's No. 2879 from western Hupeh, 

 June 1907, consisting of old twigs with rather young leaves, and some flowers 

 (1-5), but the ovate leaves show a somewhat finer and narrower serration and no 

 distinct reticulation on the upper surface. 



In shape, serration and nervation of the leaves B. Delavayi much resembles B. 

 Hookeri Lemaire, but this species is well distinguished by its sulcate young twigs, 

 its large flowers and its large fruits with 4-8 seeds. Berberis Hookeri may come 

 from the eastern Himalaya (Sikkim, Bhootan) and Upper Burma, as indicated by 

 me in Bull. Herb. Boissier, ser. 2. VIII. 197 (1908), but now I am inclined to think, 

 that it possibly may be of garden origin or that it came from South America. 

 Therefore this species has been excluded from the following key. All the forms 

 cited by me under B. Hookeri in the place quoted above may belong to B. Delavayi 

 or to a very nearly related new species. 



As, with the exception of six, all the species of this difiicult group have been 

 enumerated above, a key of all the species of this section may be appended here.
