HYMENOSPORUM 



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. 



fl4vTim, F. Muell. Lvs. usually alternate, sometimes 

 opposite or subverticillate, 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

HY0PH6KBE (Greek, food for swine; referring to 

 the fruits, probably). Palmdcew. 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 II. Verschaffeltii is yellow, while in ff. amari- 

 caiiUs 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 collpfti'.ii'* Tliuy would

 for the palm commercially known as Arrrn luhxreiis, 

 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 1.

Hyophorbe is allied to Chamasdorea 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 fis. 

 are monoecious in the same spadix and disposed in 

 small, elongated heaps : in Cham^dorea the fls. are 

 dioecious or monoecious in different spadices and spi- 

 rally disposed. Hyophorbe contains stout, spineless 

 palms with liiitjcd caudices, cylindrical, or sw.ilii-n bf-

 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, Linn. Annual or biennial, 1-2K ft. 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.
