BERBERIS 



241 



spine-tipped, and with one or more spiny teeth at each side ; the terminal 

 leaflet is stalked and ovate to lanceolate, the others sessile and shorter. 

 Flowers yellow, and produced four to eight together towards the end of a 

 raceme 2 to 3 ins. in length ; each flower on a slender stalk about ^ in. long. 

 Fruit blue, becoming dry and inflated at maturity, enclosing six to eight seeds. 

 Native of the hot, dry, south-western United States (Texas, Arizona, etc.). 

 A striking and handsome species, but too tender for the open ground except 

 in the milder counties. It may be grown on a south wall, and, wherever 

 cultivated, should be given the sunniest position available. The only species in 

 cultivation likely to be confused with this is B. trifoliolata, which has leaflets 

 of the same form and very glaucous hue, but only three of them to each leaf. 



B. GAGNEPAINII, C. K. Schneider, 



(Bot. Mag., t. 8185, erroneously us B. acuminata.") 



An evergreen shrub with clustered stems, free from down in all its parts, 

 at present 2 to 3 ft. high (perhaps ultimately 4 or 5 ft.), the branches set 

 with three-parted spines ^ to f in. long. Leaves 

 of firm texture, ii to 3 ins. long, ^ to ^ in. 

 wide ; linear - lanceolate, tapering to a fine 

 point ; dark dull green, the margins undu- 

 lated and set with slender, forward-pointing 

 teeth. Flowers in clusters of about six (some- 

 times ten or twelve) at each tuft of leaves, 

 each flower on a slender stalk J to f in. long, 

 bright yellow, | in. across. Berry black, 

 covered with blue bloom, oval, ^ to f in. long, 

 j in. wide. 



Native of Szechuen, China, introduced for 

 Messrs Veitch by -Wilson about 1904. This 

 barberry is one of the most promising of 

 Wilson's introductions from China, being ever- 

 green, of compact, neat hab"it, and flowering - 

 abundantly. Allied to B. Hookeri, it is of 

 more graceful habit. It is quite hardy at Kew, 

 and free growing. It flowers in late May. 



B. HAKEOIDES, C. K. Schneider. 



(B. congestiflora var. hakeoides, Hooker fil., BoL 

 Mag., t. 6770.) 



An evergreen shrub of loose, rather ungainly 

 habit, as much as 12 ft. high in favourable 

 situations ; branches erect, not downy, slightly 

 furrowed and but little branched. Leaves pro- 

 duced mostly in pairs, and very variable in size, 

 ranging from \ to 2^ ins. in length ; usually 

 almost orbicufar, with a heart - shaped or 

 rounded base ; thick and hard in texture, pale 

 or slightly glaucous beneath, the margins 



armed with extended spiny teeth. On the BERBERIS HAKEOIDES. 



lower, bigger leaves of the branch the stalks 



are as much as i^ ins. long, but towards the end of the branch the leaves become 

 smaller and the stalks shoiter, until finally they are sessile, The leaves spring
