LINNEARA 



LINUM 



LINNEARA (named apparently for Linnaeus). 

 Orchidacese. The Rules of Horticultural Nomenclature 

 adopted by the subsection of Nomenclature at the 

 International Horticultural Congress at Brussels, 1910, 

 provide that "multigeneric hybrids receive a conven- 

 tional generic name, preferably that of a distinguished 

 man, to which is added the termination ara. A dis- 

 tinct generic name will be formed for each different 

 combination of genera. Thus all combinations of the 

 genera Brassavola, Cattleya, Lselia and Epidendrum, 

 no matter in what order they may be intercrossed, 

 receive the same generic name which would be, for 

 example, Linneara." The Royal Horticultural Society 

 (London) had proposed to the Congress that "Future 

 multigeneric hybrids (combining three or more genera) 

 should be given a conventional name consisting of the 

 name of some person eminent as a student or as a 

 grower of orchids, followed by the termination 'ara'." 

 "A separate generic name should be coined for each 

 distinct combination of genera. Thus, Brassocattleya 

 X Epilselia, and Brassodendrum x Brassocattleya, and 

 Brassolaslia x Epicattleya, and Brassolselia x Epiden- 

 drum, and all other possible combinations of those four 

 genera would be designated by one name, e.g., Adamara, 

 while a second generic name, e. g., Linneara, would 

 need to be coined for Dialselia x Brassocattleya, and 

 this would stand for all combinations of the four 

 genera Diacrium, Lselia, Brassavola, and Cattleya." 



The Congress adopted Linneara for the hybrids of 

 the genera Brassavola, Cattleya, Lselia, t Epidendrum. 

 The name Adamara was not adopted. Neither name has 

 become current; see also Lowiara. L, jj g 



LINOSPADIX (Greek, linear spadix). Palmacese. 

 Dwarf unarmed palms varying considerably in foliage. 



Flowers monoecious, spirally arranged on the erect 

 spadix which appears among the Ivs.: Ivs. terminal, 

 flabelliform, deeply 2-cut, the apex of the lobes some- 

 times cut and thread-like. Eight species all from New 

 Guinea. The genus is allied to Bacularia, but Bacularia 

 has premorse If.-segms. and erect anthers fastened at 

 the base, while Linospadix has acuminate If.-segms. and 

 versatile anthers fastened on the back. Linospadix 

 is distinguished from Howea (which see) by the sta- 

 mens 6-9; pistillate fls. with 6-9 staminodes: ovule 

 parietal. The best known species, L. Petrickiana, is of 

 uncertain botanical affinity. The name does not appear 

 in botanical literature. This is a handsome pinnate- 

 Ivd. palm of compact growth and well furnished with 

 foliage, at least while in a young state. In its juvenile 

 condition, the Ivs. of L. Petrickiana are simply 

 bifid, the pinnate form gradually appearing as the 

 plant attains age. It was intro. in 1899 by Sander 

 & Co., who say: "The slender, alternate pinnaa are 

 slightly arched. The base is netted with brown fiber, 

 small, hair-like glumes of the same color being apparent 

 on the younger fronds and leafstalks. The young fronds 

 are colored similarly to those of Areca Ilsemannii, and 

 when developing have the luster and brilliancy of new 

 copper." Cultural conditions suited to the needs of 

 calamus and dsempnorops will be most likely to suc- 

 ceed with linospadix, and include a temperature of 70, 

 plenty of water, and some shade throughout the year. 



Petrickiana, Hort. Sander. Pinnse once cut from the 

 apex to a third or fourth the length of the pinna; 

 laterally cut about six-sevenths of the way from the 

 tips of the segms. to the rachis: premature basal Ivs. 

 cut once from the apex to half their length, the 2 lobes 

 uncut. G.C. 111.24:299. 



L. Leopdldii, Hort. Sander. Uncertain as to botanical affinity, 

 perhaps the preceding. Name never published in botanical litera- 

 ture. Shown at Ghent in 1903. G.C. III. 33, suppl. to April 25. 

 L. Micholltzii, C. H. Wright. A low, stemless palm, with a 

 densely crowded cluster of 2-cut, flabelliform, plicate Ivs.: spadix 

 slender, nodding, about 1-2J-2 ft. long, bearing numerous attrac- 

 tive, pale yellow fls. New Guinea. B.M. 8095. Not in cult, in 

 Amer., but an attractive little plant. -NT r r AVTnn 



LINOSYRIS (Linum and Osyris, which genera it 

 resembles). Composite. One species, L. vulgaris, 

 Cass., GOLDILOCKS, of Eu., is a good hardy perennial, 

 growing J^-2 ft. high, and bearing numerous small pale 

 yellow usually rayless heads: sts. strict (from a hard 

 root), striate, glabrous, bearing many alternate, small, 

 linear, entire Ivs. : involucre imbricated, the numerous 

 narrow bracts shorter than the florets and pappus: 

 achene compressed and silky. The plant grows natively 

 in rocky and stony places and along gravelly banks of 

 rivers in England, Wales, and through Cent, and S. 

 Eu. to the Caucasus. It is an excellent late summer 

 and fall bloomer, thriving well in any good garden or 

 border. Prop, by division. 



The genus Lynosyris is referred to Aster by many 

 botanists, the above species then becoming Aster Lino- 

 syris, Bernh. It is also known as Chrysocoma vulgaris, 

 Linn. Horticulturally, it is distinct, with its yellow 

 heads and peculiar habit. From Aster it differs techni- 

 cally in the absence of rays and in yellow flowers, 

 but rayed heads are sometimes found. In this work, 

 the yellow-flowered asters are kept distinct in this 

 genus and Calimeris. As usually separately defined, 

 Linosyris contains several species. L H. B. 



LINUM (classical name). Including Cathartollnum. 

 Linacese. FLAX. Ornamental flowering plants, annual 

 and perennial; one is the fiber-yielding flax. 



Erect-growing plants, bearing tough cortex, with 

 narrow alternate (rarely opposite) and mostly entire 

 Ivs., and showy 5-petaled fls. which open in the sun- 

 shine: stamens 5 and alternate with the petals, usually 

 united at the base, staminodia sometimes present: 

 ovary single, 3-5-loculed, bearing as many styles as 

 locules, and ripening into a dry caps, which may or 

 may not be dehiscent: fls. red, blue, yellow, white, 

 borne, in terminal racemes or cymes, and, although 

 each fl. may be short-lived, the continuity of bloom 

 makes the plant showy. Species 90-100, in temperate 

 and warm regions about the globe, about one-fourth of 

 which are in the U. S.. There are two horticultural 

 sections, the annuals and perennials. All are of easy 

 cult, in an open and warm place, fully exposed to the 

 sun. Seeds of the annuals may be sown where the 

 plants are to bloom or they may be started under glass. 

 The perennials often bloom the first year from seed, and 

 seeds are often used to prop, them; but the plants may 

 be divided. The species with capitate stigma and 

 glandular sepals, mostly yellow-fld., are by some authors 

 separated as Cathartolinum.

1. grandifldrum, Desf. FLOWERING FLAX. Fig. 

 2180. Erect, branchy, 1-2 ft., glabrous: Ivs. many, 

 alternate, broadly lanceolate to oblong, sessile or nearly 

 so: fls. terminating very slender pedicels which are 1-3 

 in. long, the obovate petals wide-spreading (fl. 1-1 J^ 

 in. across, and something like a single-fld. pink) and 

 much exceeding the pointed scarious-edged sepals. 

 N. Afr. B.M. 4956. R.H. 1848:401. Very serviceable 

 garden annual, and popular for its glossy bright fls. 

 The color varies in the shades of red. Var. rilbrum has 

 bright red fls. Var. kermesinum is crimson. Var. 

 coccineum, Hort., is a scarlet-fld. form. In a warm, 

 sunny place, the flowering flax makes a very satis- 

 factory plant of long period of bloom. It is not 

 adapted to cutting, since the fls. are not durable. Will 

 not stand frost.
