Jessenia—continued. 
(three species) of stove, unarmed Palms, allied to 
Euterpe, natives of South America. Flowers mediocre, 
moncecious on the same spadix; spathes two, fusiform ; 
spadices pendulous, shortly pedunculate. Leaves terminal, 
yery numerons, equally pinnatisect; segments crowded, 
opposite, ensiform. J. amazonum is grown at Kew, but 
it is not in general cultivation.

JUGLANS. To the species and varieties described 
on pp. 210-11, Vol. II., the following should be added. 
Several species formerly classed hereunder are now 
referred to Carya and Pterocarya. 
J. regia. The following varieties may be mentioned: hetero- 
phyla, leaflets laciniate; maxima (SYN. macrocarpa), nut very 
large; monophylla, leaves with only one leaflet, a curious 
form; and serotina. 
J. Sieboldiana (Siebold’s). The correct name of J. ailanti- 
Solia. 
J. Vilmoriniana (Vilmorin’s). jr. globular. 7. having about 
five pairs of ovate, coriaceous, glabrous leaflets. The origin 
of this tree is uncertain; but it is said to be a hybrid between 
J. regia and J. nigra. (G. & F. 1891, p. 52, f. 11, 12.) 
JUJUBE LOTUS. See Zizyphus Lotus. 
JULIANA. A synonym of Choisya (which see). 
JULIDZ. This is one of the families into which 
the Order Chilognatha is split up by natnralists. It 
contains the very familiar Millipedes (which see), and 
is characterised by having a cylindrical body; by the 
possession of more than thirty rings, and many eyes in 
a cluster. All the species usually met with are more or 
less injurious. The best known is J. terrestris. 
JUNCAGINEZ. Included under Naiadacee (which 
see). 
JUNCUS. Including Tenageia. According to Hooker, 
sixteen species of this genus are natives of Britain. 
JUNGIA (named in honour of Joachim Jung, of 
Liibeck). Syns. Dumerilia (of Lagasca), Martrasia, 
Rhinactina, Trinacte. Orpd. Composite. A genus com- 
prising about a dozen species of stove or greenhouse, 
erect or somewhat climbing, sub-shrubs or tall herbs, 
natives of South America from Chili to Brazil, and 
extending as far as Colombia. Flower-heads yellow or 
pink, small or mediocre, homogamous, paniculate at the 
Eupatorium pur- 
Jungia—continued. 
tips of the branches ; inyolucre cylindrical or campanulate, 
the bracts in one or two series. Leaves alternate, 
varying from orbicular to linear. It is doubtful if 
J. rugosa (J. spectabilis of gardens), the only species intro- 
duced, is still in cultivation. 
JUNIPERUS. Junipers may be increased by grafting 
on the common species in spring, and plants so raised 
make good-sized specimens in less time than those 
raised from cuttings. Young, well-ripened shoots of 
the previous summer’s growth should be selected, and if 
they are placed in a warm close case a union -will be 
effected in a few weeks’ time, after which they should be 
gradually hardened off, neatly staked, and grown on in 
cold frames until ready for planting out the following 
spring in nursery rows in the open ground, the soil most 
suitable being composed of fibrous loam and leaf-mould. 
Some of the dwarf-growing forms are well suited for 
planting on rockeries. A few of the best are J. sabina 
and its varieties, J. procumbens, J. littoralis, J. com- 
munis, and J. c. awreus. 
Dispases. Junipers are attacked by several species of 
fangi, one of the worst being Trametes radiciperda 
(Fomes annosus), which causes the well-known Root-Rot 
upon J. communis and certain other Conifers (see Pinus 
—Fungi, Vol. III.). <A very distinct species causing great 
destruction on the Continent is Herpotricha nigra (sce 
Pine-Leaf Fungi). Then there are no fewer than four 
species of very complex fungi belonging to the genus 
Gymnosporangium (which see), whose teleutospore stage 
is passed upon the Common Juniper or some of its 
near allies. G. clavarieforme produces in late spring 
somewhat leathery yellow masses from swollen spots on 
the branches ; the ecidium, or cluster-cup, stage is passed 
upon the Hawthorn or upon the Pear or a close ally. 
G. sabine is found upon several ‘species of Juniper, the 
teleutospores being of a dirty-brown colour ; the xcidium- 
stage causes the disease known as Pear-Leaf Rust 
(Roestelia cancellata), described and illustrated in Vol. III. 
G. confusum, as regards its ecidinm-stage, is passed upon 
the Medlar and the Quince, and the shredded cluster- 
cups may be found on the hardened orange spots on the 
infested leaves. G. juniperinum forms its teleutospores 
upon the Common Juniper and J. c. nanus, but passes 
its «cidium-stage upon Mountain Ash foliage, where the 
torn cluster-cups are found upon deep orange spots. 
In all these cases the remedy is to get rid of one o1 
other of the host-plants, often a most difficult matter, 
as they may be situate some distance from the infested 
area, 
To the species and yarieties described on pp. 211-14, 
Vol. IL., the following should be added : 
J. communis aureus (golden). An elegant, drooping form, 
golden-tinted. 1896. 
J. conferta (crowded). A synonym of J. Jittoralis. 
J. davurica (Dahurian), 7. opposite or in whorls of three; 
those on the male plant very small, imbricated in four rows, 
shortly pointed; those on the females whorled, linear, aw]- 
shaped, spreading, sharp-pointed, densely disposed, channelled 
and whitish above, convex at back. Branches terete, forked, 
widely spreading. Dahurian Mountains, 1791. 
J. foetidissima (very fetid). 7. on the branches and primary 
branchlets ovate or lanceolate, acuminate, quadrifariously 
opposite; those on the secondary branchlets ovate-rhomboid, 
slightly acute, convex on the back. Branches terete, erect; 
branchlets somewhat tetragonal. Orient. A shrub (lOft. to 
12ft. high) or tree, often confused with J. excelsa. 
J. littoralis (shore-loving). fr. tawny-brown, with a violet 
bloom, globose, rather above 4in, long. 7. thickly placed in 
threes, linear, three-sided, rigid, openly imbricated, sharp- 
jointed, 4in. long, half a line wide; upper side channelled and 
ongitudinally white-marked, the under one convex and keeled. 
Japan. Allied to J. rigida, but the leaves are more crowded. 
Syn. J. conferta. 
J. mexicana (Mexican). 7. in opposite pairs, only ;,in. long, 
ovate, closely imbricated on the small branches in four rows, 
dull greyish; those on young plants mostly in threes. Branches 
angular, horizontal, ascending at the ends. h. usually 20ft. to 
30ft. Mexico. Only hardy in warm situations. 
J. pseudo-Sabina (false Savin). J. those on the lower 
branches linear, pungent, those on the terminal branchlets 
quadrifarious, closely imbricated, appressed, the largest 4in. 
long, rather spreading, the smallest j,in. long, rhombic-ovate. 
Temperate Himalayas, &c. A robust shrub or tree. 
J. Sanderi (Sander’s). A compact, dense-growing, dwarf 
species, said to have been introduced from Tibet. 1899.
