ULMUS UMBELLULARIA 621 



U. VEGETA, Lindley. HUNTINGDON or CHICIIESTER ELM. 



This fine elm, according to information given to Loudon by Mr John 

 Wood of Huntingdon, in 1836, was raised in the nursery of his firm about 

 the middle of the eighteenth century from seed gathered in Hinchingbrook 

 Park. It is, no- doubt, a hybrid between U. montana and U. nitens, and like 

 many hybrid trees, is of remarkably vigorous growth. One of the largest 

 of all elms, it reaches 100 ft. in height, forming a thick short trunk 5 or 6 ft. 

 in diameter with ascending branches. Leaves up to 5 or 6 ins. long, more 

 than half as wide, smooth above and downy beneath only in the leaf-axils. 

 Fruit oval, up to ^ in. long, the seed not reaching to the notch at the top. 

 This last character and its less downy leaves distinguish it from U. major, 

 of presumably the same parentage. The veins, too, are more numerous 

 (fourteen to eighteen pairs) than in U. major. According to Elvves it has 

 the defect of splitting in the trunk due to its habit' of forking low down. 

 This, however, can be prevented by timely pruning. The tree produces 

 suckers. 



U. VIMINALIS, Loddiges. 



A narrow-headed, rather slender tree with drooping branches; young 

 shoots slightly downy, slender. Leaves oblanceolate or narrowly oval, 

 nearly always tapered at the base, terminated by a long slender point; i to 

 2 ins. long, \ to f in. wide; very deeply toothed, the teeth narrow, often 

 blunt; upper surface very rough, lower one downy especially in the vein- 

 axils and on the veins. I have never seen it bearing fruit although it 

 flowers. Several varieties of U. viminalis are in gardens : 



Var. AUREA (syns. Rosseelsii; antarctica aurea). Leaves yellow. 



Var. VARIEGATA. Leaf margins variegated with creamy white. 



U. viminalis is a charming small tree for gardens, very elegant and not 

 growing fast. It is of uncertain origin, but is probably a seedling of some 

 hybrid elm. 



U. BETUUEFOLIA, Loddiges, appears to be allied to U. viminalis, and is 

 also of uncertain origin, possibly a hybrid in whose origin U. nitens has 

 shared. The leaves are narrowly obovate, up to 2^ ins. long by I \ ins. wide, 

 the margins deeply toothed, the teeth narrow, incurved, often again toothed, 

 very harsh to the touch above, downy in the vein-axils beneath. The habit 

 is elegant on account of the pendulous young branchlets. 



UMBELLULARIA CALIFORNICA, Nuttall. CALIFORNIAN 

 LAUREL. LAURACE^:. 



(Oreodaphne californica, Nees ; Bot. Mag., t. 5320.) 



An evergreen tree, So to 100 ft. high in favourable situations in 

 California, with a dense head of very leafy branches; young shoots at 

 first minutely downy. Leaves alternate, leathery, with a pungent aromatic 

 odour when crushed, narrowly oval or oblong, but tapered at both ends ; 

 2 to 5 ins. long, j to ij ins. wide; not toothed, dark green and glossy 

 above, paler beneath, almost smooth on both surfaces except when just 

 unfolding. Flowers \ in. across, yellowish green, produced during April 

 in terminal and axillary umbels f in. wide, on a common stalk i in. 

 long. Fruit roundish pear-shaped, 'i in. long, f in. wide ; green changing 

 to purplish.
