Gn. 49, p. 151. G.C. II. 26:425; III. 8:665. G. 18:693; 

 21:661. G.W.5:367, 571; 12:413. Thrives in drier 

 soil. Var. major, Hort., is a very strong-growing form. 



AA. Lvs. of ordinary or even small size. 



arenaria, Cheesem. Prostrate and creeping plant 

 making extensive patches in damp sandy land in New 

 Zeal., the rhizome stout and clothed with bases of old 

 foliage: Ivs. 2^ i n - or I GSS l n g> thick, only slightly 

 hairy, the blade less than 1 in. and broadly ovate 

 or oblong, crenate or somewhat lobed: male peduncles 

 usually longer than Ivs., and female much shorter 

 at flowering time; female fls. densely crowded into 

 a short oblong spike: drupes very small, fleshy, yel- 

 lowish red. 



dentata, Kirk. More slender, forming extensive 

 patches in wet subalpine places in New Zeal. : Ivs. many 

 and tufted, prominently hairy, the blade 1 in. or less 

 long and varying from ovate to oblong and elliptic- 

 lanceolate, coarsely dentate: male spikes about equal- 

 ing the Ivs., the female short and hidden at the base of 

 the Ivs., but the spikes in fr. sometimes surpassing the 

 Ivs.: drupes minute (ruin, long). 



magellanica, Lam. A very small species with dark 

 green Ivs.: stolonif erous : Ivs. orbicular-reniform, cre- 

 nate, 2]/z in. or less broad: male scape surpassing the 

 Ivs., female shorter: fls. apetalous, the male pedicelled, 

 the female sessile. Chile south, and Falkland Isls. 



G. brephogea, Lind. & Andre. A large species: Ivs. tall-petiolate, 

 the limb peltate, concave, orbicular-reniform, rather shallowly 

 7-9-Iobed and the lobes again somewhat lobed or angled, the mar- 

 gin with many small acute inflexed teeth and black-purple: female 

 fls. in a lax spike-like panicle, on a purplish scape. Colombia. 

 I.H. 19:111. -G. minima, Hort.=G. magellanica (?). G. perpensa, 

 Linn. Lvs. long-petioled (12-18 in.), orbicular.-reniform, cordate 

 at base, 6-12 in. across, uniformly and closely crenate-toothed: 

 scape surpassing the Ivs., becoming 2-3 ft. high; fls. monoecious, 

 the males in the upper part of the slender spikes. S. Afr. in moist 

 places. B.M. 2376. L. H B 



GURANIA (Anagram of Anguria). Cucurbitdcex. 

 Tall climbers, perennial herbs or shrubs, with simple 

 tendrils: Ivs. entire, lobed, or 3-5-f oliolate : fls. direcious 

 or rarely monoecious, small, bractless, the petals pale 

 yellow; male fls. in long-peduncled clusters, the calyx- 

 tube cylindrical or ventricose and the limb 5-parted, 

 the corolla 5-parted into linear or triangular papillose 

 thickened segms., the stamens 2 and free; female fls. 

 solitary on fascicled or capitate on the top of the 

 peduncle, staminodia none, ovary oblong and bearing 

 a bifid style: fr. oblong, terete, many-seeded, the seeds 

 ovate and compressed. There are about 50 guranias in 

 the American tropics, one of which, G. malacophylla, 

 Rodr. (G. eridntha, Andre, not Cogn.), has recently been 

 mentioned in horticultural literature abroad. This 

 is a strong villous climber with simple broadly ovate 

 sometimes 3- to 5-lobed Ivs. 4-8 in. long: male fls. 

 reddish, in a globose head on a peduncle 6-16 in. 

 long; petals linear-subulate, pubescent ; female fls. 

 not described. Upper Amazon. B.M. 8085. R.H. 

 1904:388. L . H. B. 



GUSTAVIA (Gustavus III, King of Sweden). 

 Lecythidacese. Trees and shrubs of the American tropics 

 with large showy fls., of which G. speciosa, HBK., is 

 offered in S. Calif. It is a thick-lvd. tree with 6-petaled 

 white fls., suitable for planting in the open. For fuller 

 account, see Japarandiba. 



GUTHNICKIA. Two plants now referred to 

 Achimenes, one of which, A. foliosa, is perhaps some- 

 times cult. (See Vol. I, p. 208.) 



GUTIERREZIA (personal name). Compdsits:. Herbs 

 or subshrubs, often resinous, mostly western North 

 American, rarely planted in borders. 



Much branched from the base, and have narrow 

 alternate entire Ivs. and clusters of small yellow heads 

 with flat receptacles and hairy achenes. About 18 



species. Easily cult, in Calif.; doubtfully hardy on 

 Atlantic coast north of Washington. 



Euthamiae, Torr. & Gray. More or less wood}' at 

 base, seldom to \Yi ft. high: Ivs. linear, crowded: 

 involucre turbinate, 2 lines long; rays and disk-fls. 

 each 3-9: achenes silky-pubescent; pappus of about 

 9 chaffy scales. W. N. Amer. N. TAYLOR.t 



GUZMANIA (A. Guzmann, Spanish naturalist). Bro- 

 melidcese. Includes Caraguata and Massdngea. Tropi- 

 cal American bromeliads, of which several are fairly 

 well known ornamental glasshouse subjects. 



They closely resemble the erect-growing tillandsias, 

 but differ in technical characters: fls. in a simple spike- 

 like terminal cluster, tubular, the outer segms. or calyx 

 oblong and obtuse, the inner or petals shorter than 

 the tube; anthers inserted on the throat of the tube, 

 and united by their edges around the style. About 

 75 species. Grown in the warmhouse, along with Bill- 

 bergia and Tillandsia, which see for culture. Closely 

 allied to ^Echmea. Many species are cult, in fanciers' 

 collections in the Old World. For G. picta, see Nidu- 

 larium. For G. Legrelliana, see Hohenbergia. G. rosea, 

 a name which has appeared in the American trade, is 

 probably an .Echmea. 



A. Calyx corolla-like, exceeding the petals. 



musaica, Mez. Lvs. strongly decurved, beautifully 

 and densely marked with undulating, interrupted, irregu- 

 lar brown lines: infl. 3-4 in. long, on a short peduncle, 

 the bracts golden, striped with rose; fls. l%-2 in. long. 

 Colombia. B.M. 6675. I.H. 24:268. 



AA. Calyx not corolla-like, shorter than petals. 



B. Corolla (or segms.) purple or red. 

 lingulata, Mez (Caraguata linguldta, Lindl. C. 

 splendens, Bouche. C. lingulata splendens, Hort.). 

 Epiphyte: Ivs. many, lanceolate or ensiform, 1J^ ft. 

 long, remotely toothed: spike becoming drooping, 

 showily red-bracted; expanded fl. about as long as the 

 long-pointed bracts, the tube yellowish and the limb 

 blue-purple. W. Indies, Cent. Amer., and S. Amer. 

 B.R. 1068. F.S. 11:1091. Handsome. Var. cardinalis, 

 Andre (Caraguata cardinalis, Andr6). Bright scarlet: 

 very showy. Colombia. I.H. 27:374. R.H. 1883:12. 



BB. Corolla (or segms.) white. 



tricolor, Ruiz & Pav. (G. frdgrans, Hort., at least 'in 

 part. G. grdndis, Hort., in part. G. maculdta, Hort., in 

 part. G. monostdchya, Rusby). Lvs. several to many, 

 broad and more or less recurved, entire on the edges, 

 usually shorter than the stout, erect spike: lower bracts 

 green streaked with black, upper ones red-tinged: 

 corolla white. W. Indies, Cent. Amer., S. Amer. 

 L.B.C. 5:462. F.S. 9:918. B.M. 5220. Var. variegata, 

 Hort. Lvs. striped with white. S. Fla. Interesting 

 because of its combination of green, red and white. 

 Some, at least, of the horticultural plants which pass as 

 G. fragrans belong to Mchmea eburnea, Baker (Canis- 

 trum Lindenii, Mez. Nidularium Lindenii, Regel). This 

 species is further mentioned under Nidularium. 



Devansayana, Morr. (Caraguata Devansaydna, 

 Morr.). Lvs. about 20, narrow linear or ensiform, 

 brown-striped on the back: fls. white, in a dense, oblong 

 spike, the scarlet bracts oval. Ecuador. 



BBB. Corolla (or segms.) yellow. 



Melinonis, Regel (Caraguata Melindnis, Morr.). Lvs. 

 strap-shaped, green above and brown-tinted beneath: 

 fls. yellow, subtended by oblong red bracts. French 

 Guiana. GEORGE V. NASH.f 



GYMNOCLADUS (from Greek naked, plus a branch, 

 which refers to the stout branches with few branch- 

 lets). Legiimindsx. Trees, useful for bold planting. 



Flowers dioecious or polygamous, regular, not 

 papilionaceous; calyx tubular, 5-cleft; petals 5, oblong,
