662 JASMINUM JUGLANS 



green above, paler and brighter green beneath ; stalk of terminal leaflet up to 

 f in. long ; of the others, very short or absent. Flowjers yellow, fragrant, pro- 

 duced in terminal corymbs of six, twelve, or more together. On very vigorous 

 shoots the terminal inflorescence is augmented by two or three axillary ones, 

 making the whole cluster forty- to fifty-flowered, and about 5 ins. across. 

 Corolla | to i in. across ; calyx-lobes about one-third as long as the cup, 

 triangular. 



Native of Afghanistan and the north-west Himalaya. It varies somewhat in 

 size of leaf, and the jasmines known in gardens as J. Reevesii and J. triumpbans 

 are this species. It is nearly allied to J. Wallichianum (g.v.\ and like it is 

 sometimes cut back in winter, but as it flowers from June onwards on the shoots 

 of the year this is not of much consequence. Still, a sheltered spot should be 

 given to it. Belonging to the same group of alternate-leaved jasmines with very 

 short calyx-lobes is J. HUMILE, Linnceus, a native of S.E. Europe. It is a 

 dwarf plant with nearly always ternate leaves, and one to four flowers on a 

 stalk. It was cultivated by Tradescant in 1656, but being rather tender, and 

 not so ornamental as either revolutum or Wallichianum, has probably dis- 

 appeared from cultivation. It used to be known as "Italian iasmine" 

 (Bot. Reg., t. 350). 



J. WALLICHIANUM, Lindley. 



(Bot. Reg., t. 1409.) 



A nearly evergreen shrub, with slender, angled, smooth branchlets. Leaves 

 alternate, composed of seven to thirteen leaflets which are lanceolate to ovate, 

 taper-pointed, \ to i\ ins. long, \ in. or more wide; the terminal one much the 

 longest and largest, dark green ; both blade and stalk sometimes more or less 

 downy. Flowers yellow, J in. long, \ in. across the rounded, spreading lobes ; 

 produced in a cluster at and near the end of the shoot, solitary on the stalk, or 

 often in triplets. Calyx-lobes about one-third as long as the cup, triangular, 

 downy. 



Native of Nepal ; introduced about 1812. It is most nearly allied to 

 J. revolutum, differing in the greater number and smaller size of the leaflets, 

 in the few flowers on the cyme, and in being less robust. Both these species 

 differ from the two other alternate-leaved jasmines in the very short, com- 

 paratively broad calyx-lobes. 



JUGLANS. WALNUT. JUGLANDACE^:. 



The walnuts, of which eight or nine species are in cultivation, are 

 deciduous trees, or occasionally shrubs, with pinnate leaves aromatically 

 scented. Flowers unisexual, both sexes on the same plant; the male 

 flowers very numerous in slender, pendulous catkins, with many stamens 

 produced in the axil of a lobed scale .; female flowers few. The male 

 catkins (rather elegant in the Asiatic species) are borne towards the 

 end of the previous year's shoots; the nut-bearing spike terminates the 

 young shoot of the current season. Fruit a hard-shelled nut, surrounded 

 by a thin or fleshy husk. The cultivated species are from Europe, 

 N. Asia, and N. America, but two or three species of which little is 

 known are found in S. America. The only other genus of trees with 

 which Juglans is likely to be confused is Carya (the hickories), but among 

 other differences, Jugfans is distinguished by the pith of the young shoots 

 being in thin transverse plates, thus dividing the hollow portion of the
