HYMENOSPORUM 



in. S. Calif. It lias oorj-mbs of tubular yellow fls. each 

 1 In. or more across. The genus has only one species, 

 an evergreen Australian shrub, with the habit of Pittos- 

 porum and resembling that genus in having thick, 

 leathery capsules and an indefinite number of seeds, but 

 in Pittosporum the seeds are thicker, not so much flat- 

 tened and not winged. 



£14vuni, F. Muell. Lvs. usually alternate, sometimes 

 opposite or subvertieillate, becoming nearly 9 in. long, 

 obovate, leathery, entire: co- 

 rolla with 5 obovate lobes, silky 

 outside, marked with red at 

 the throat ; stamens 5. B.M.

HY0PH6RBE (Greek, food for swine; referring to 

 the fruits, probably). Pabndcece. Three species of pin- 

 nate palms from Mauritius, 2 of which are cult, under 

 glass North and outdoors South. Much of their distinc- 

 tive beauty is in the color of the petiole and rachis, 

 which in JT. VerschaffelHi is yellow, while in H. amari- 

 eaulis the petiole is maroon and the rachis orange. The 

 first species also has its leaves handsomely veined with 

 white. 



These two species are highly ornamental palms, and 

 are frequently found in trade collections. They would 

 probably be grown in greater quantities were it not for 

 the fact that they are not very rapid growers while in a 

 young state. They are naturally heat-loving plants, and 

 flourish under similar treatment to that recommended 

 for the palm commercially known as Areca liitescens, 

 namely, a good loamy soil well enriched with stable 

 manure and with a moderate addition of bone dust, firm 

 potting, an abundance of water, and a night tempera- 

 ture of G5°, while in common with palms in general 

 when grown under glass, it is found necessary to shade 

 from full sunshine during the period between March 1 

 and November I. 



Of the two species, H. VerschaffeUii is much the bet- 

 ter, and is one that should be found in all collections, 

 its stout and usually triangular stem and well furnished 

 foliage giving it a distinction that readily attracts at- 

 tention. Seeds of Hyophorbe should be sown in a light 

 compost, pure peat giving good results for this purpose, 

 the seed pots being placed in a bottom heat of 80° and 

 kept moist. The seedlings are delicate in their earlier 

 stages, and should be kept in a warm place until thor- 



oughly established ; they also require careful watering, 

 the roots of these small plants being quite tend,er. 



Hyophorbe is allied to Chamaedorea and Roscheria, 

 which are cultivated. Hyophorbe is spineless and the 

 leaf segments are acuminate, while Roscheria has spines 

 and segments 2-cut at the apex. In Hyophorbe the fls. 

 are monoecious in the same spadix and disposed in 

 small, elongated heaps : in Chamsedorea the fls. are 

 dioecious or monoecious in different spadices and spi- 

 rally disposed. Hyophorbe contains stout, spineless 

 palms with ringed caudices, cylindrical, or swollen be- 

 low the middle or interruptedly swollen : lvs. terminal, 

 equally pinnatisect, the subopposite segments linear- 

 lanceolate, acuminate, plicate-nerved, with the thick- 

 ened margins recurved at the base; petiole subcylindri- 

 cal, the upper surface slightly furrowed, 3-sided at the 

 base; sheath large, swollen, entire: spadices with short 

 peduncles, twice-branched, the branches slender, spread- 

 ing ; spathes numerous, imbricated in 2 rows : fls. pale 

 greener yellow: fr. small, pear-shaped or olive-shaped, 

 straight or curved, gibbous or bigibbous at the base, 

 orange or blue. 



amaricatilis, Jlart. {Areca specidsa, Hort.). Palm 

 60 ft. high, with a bottle-shaped caudex, 15-21 in. in 

 diam. near the ba.se, slightly diminishing upwards to 

 the base of the leaf-sheaths and there abruptly con- 

 stricted : petiole 12-18 in. long, somewhat trigonous, 

 grooved on the face ; segments in 40-GO pairs, 18 in. 

 long, 2 in. broad, with the central and 1 lateral vein on 

 each side prominent above, the veins clothed below with 

 rather rigid, lanceolate, appressed scales I.H. 13:462.

VerschaSf^ltii, H. Wendl. {Areca Verscliaffiltii, 

 Hort.). Caudex 25-30 ft. high, 6-12 in. in diam. at the 

 base, bulging after a few feet, reaching 12-24 in. in 

 diam. in the middle, thence contracting upward : petiole 

 3 in. long, subterete, slightly grooved on the upper sur- 

 face, witli a yellow band extending from the upper part 

 of the leaf-sheath along the face of the petiole to the 

 base of the blade : segments in 30-50 pairs, 20-30 in. 

 long, 1 in. wide, only the central vein prominent, clothed 

 on the under surface toward the base with short, linear 

 scales. Mauritius. I.H. 13:462. G.C. 1870:418.

HYOSCtAMUS (Greek, hog's iean). Solandceoe. 

 Henbane is a coarse, clammy, ill-smelling, annual or 

 biennial wayside weed which is cultivated for medicinal 

 purposes. An extract is commonly sold in drug stores. 

 About 15 species of herbs, biennial or perennial, pilose 

 or glabrous: lvs. wavy-margined, coarsely toothed, or 

 pinnatifid, rarely entire : corolla pallid, or lurid and 

 netted-veined, funnel-shaped, with 5 unequal lobes : 

 capsule circumscissile above the middle. The nearest 

 ally of garden value is Datura. Henbane grows wild in 

 Eu., W. Asia and Himalayas and is naturalized in 

 Amer. It is found in sandy and waste places. Seeds 

 can be obtained by the pound or less. For medicinal 

 purposes, only the leaves of the second year's growth 

 should be used. 



nlger, Ijinn. Annual or biennial, l-2Kft. high: lvs. 

 3-7 in. long, the upper ones stem-clasping, irregularly 

 lobed or pinnatifid: fls. greenish yellow, with purple 

 veins. June-Sept. B.B. 3:138. 



HYF^RICUM (old Greek name of obscure meaning 

 used by Dioscorides). Syperiedcece. St. John's-Wokt. 

 A genus of about 200 species, consisting of herbs, un- 

 der-shrubs and shrubs, and scattered over the whole 

 world, but particularly abundant in S. Europe, W. Asia 

 and N. Amer.; few species of any value in the garden. 

 The leaves are opposite, oblong or lanceolate, exstipular, 

 sessile or subsessile, entire, subevergreen or deciduous, 

 dotted with pellucid or opaque glands, rich in volatile oil. 

 Flowers polypetalous, terminal, solitary or disposed in 

 single or compound cymes, appearing .July-Oct., but 

 particularly in early August ; sepals 4-5. more or less 

 united at the base and unequal, petals commonly yel- 

 low, 4-5, oblique or contorted, hypogynous, alternate 

 with the calyx; stamens numerous, free or connate, in
