JUGLANS 



JUNCUS 



and broad ridges at the sutures. Originated in France 

 and in several places near Boston and probably else- 

 where. G.F. 7:435 (adapted in Fig. 2019). R.H. 1870, 

 p. 494. Gn. 50, p. 478. The form figured by Carriere 

 seems much nearer to J. cinerea^ while the form origi- 

 nated near Boston is more similar to J. regia. 



2017. Juglans Sieboldiana var. cordiformis. (Natural size) 



Besides these described above, several other hybrids have been 

 reported. Luther Burbank raised a hybrid between J. Hindsii and 

 J. nigra, named "Royal," with large nuts of excellent flavor, and one 

 between J. Hindsii and J. regia, named "Paradox," a very vigorous 

 grower, but a shy bearer. There are supposed hybrids between J. 

 mandschurica X J. regia, J. cinerea X J. nigra and J. cinerea X J. ru- 

 pestris; J. longirostris, Carr. (R. H. 1878, p. 53), may be a hybrid 

 between J. regia and J. major, which often has a fr. similar in shape 

 to the one figured. J. austrdlis, Griseb. Allied to J. rupestris. Lfts. 

 13-21, large, ovate-oblong, abruptly acuminate, serrate, viscid- 

 pubescent: nut ovoid, acute, small, slightly grooved. Argentina. 

 J. cottdpsa, Dode. Allied to J. mandschurica and probably only a 

 variety, but nut less rugose, less sharply angled, with ovoid de- 

 pressions. Probably from N. China. J. kamadnia, Dode (J. regia 

 var. kamaonia, DC.). Allied to J. regia. Lfts. 5-11, oblong-elliptic 

 to oblong-lanceolate, puberulous on both sides, rufous-pubescent on 

 the veins beneath: nut globose, rather hard-shelled. Himalayas. 

 J. stenocdrpa, Maxim. Closely allied to J. mandschurica. Lfts. 

 narrower, more coarsely serrate, more pubescent, the terminal 1ft. 

 very large: fr. more oblong, less strongly ridged. Manchuria.

JUjCfiE: Zizyphus Jujuba. 



JULIANIA (Julian Cervantes). Doubtfully associated 

 with the Anacardiacese, but now made the type of the 

 family Julianiacex. Tortuously branched resinous 

 dioecious shrubs or small trees of Mex., perhaps not in 

 cult.: Ivs. alternate, unequally pinnate, the Ifts. 3-11: 

 fls. small, green; male fls. and infl. much like those of 

 the oak, "a single, hairy, thin perianth, divided nearly 

 to the base into 5 or 7 acute segms., with as many 

 stamens alternating with the segms."; female fls. 2-4 

 in an involucre, the whole having the appearance of a 

 single fl., of curious structure: fr. composite, dry, with 

 an exceedingly hard involucre, indehiscent, germina- 

 tion taking place through the apex. The known spe- 

 cies are 4, one of which, J. adstringens, Schlecht., is 

 figured in G.C. III. 43:99, by Hemsley (adapted from 

 Trans. Roy. Soc. of London). Aspect somewhat like 

 some species of Rhus: Ifts. 5-7, sessile or the terminal 

 very short-stalked, 1-1 ^ in. long, obovate or oval, 

 dentate: fr. 2 in. long, enlarging upward. J.Huaucui, 

 Gray, of Peru, is referred to Orthopterygium; probably 

 not in cult. 



J0NCUS (classical name, to join). Juncacese. 

 RUSHES. Grass-like plants growing in wet, rarely in 

 dry, places and used for planting in bogs and around 

 aquatic gardens. 



Plants send up from the rootstock several unbranched 

 cylindrical sts. which bear a terminal, or sometimes 

 apparently lateral, cyme of greenish or brownish very 

 small fls.: Ivs. grass-like terete or flat: perianth of 6 

 rigid chaffy parts in 2 whorls; stamens short, either 3 

 or 6: caps. 3-celled or rarely 1-celled, many-seeded. 

 Rushes differ from the true grasses and sedges in hav- 

 ing a true perianth and a many-seeded pod. The 

 genus includes a host of species distributed throughout 

 the temperate regions, but most of these are not in 

 cult. Rushes are sold by dealers in native and aquatic 

 plants. The kind used in making mats in Japan is 

 procurable from dealers in Japanese plants. 



A. St. without Ivs.: cymes apparently lateral. 

 effftsus, Linn. (/. communis, Hort.). COMMON 

 RUSH. Fig. 2020. St. soft, 1-4 ft. high: cyme diffuse, 



2018. Juglans intermedia var. Vilmoreana. ( X Vz) 



2019. Juglans quadrangulata. ( X 1 A) 



1-2 in. long, the fls. separate; sepals acute, equaling 

 the short retuse and pointless or mucronate greenish 

 brown caps.; stamens 3: seeds not tailed. North Tem- 

 perate Zone. Used also for weaving into mats, and the 

 like. Var. compactus, Lej. & Coutt. (var. congestus, 

 Hort.). Fls. small, %-!% lines long: cyme congested 

 into a spherical head: culms rather stout, finely many 

 striate. Much of the J. conglomerate of the trade is 

 probably this variety. Var. conglomerates, Engelm., 

 is similar to the last, but the culm coarsely few (12-15) 

 striate, and perianth very dark. Var. solutus, Fern. & 

 Wiegand. Fls. medium, 1%~2}4 lines long; perianth 

 semi-appressed : cyme open: culms coarse with usually 

 pale basal sheaths, at least when dry. Var. Pylaei, 

 Fern. & Wiegand. Fls. medium; perianth spreading:
