AGDI^STIS (a mythical hermaphrodite monster, the 

 penus being an anomalous one in its order). Phytolac- 

 vi}ce(F. Amonotvpicgenus. Tender climbing shrub from 

 Mex. Cult, in Calif, 



clematidea, Moq. & Sesse. Lvs. alternate, petiolate, 

 cordate: fis. axillary or in terminal, branched, racemose 

 cymes, white, star-shaped; sepals 4; petals 0. 



AGERATUM {Greek for not growing old, probably 

 applied first to some other plant). Comp6sit(e. About 

 40 species of trop. Amer. herbs, with opposite stalked 

 lvs. and blue or white fis. in small terminal cymes or 

 panicles. 



conyzoides, Linn. (A. Mexlcdnum, Sims, and Hort.). 

 Fig. 51. Annual and pubescent: Ivs. ■ ovate-deltoid, 

 rrenate-serrate : fls. blue or white, or varying to rose. 

 Ordinarily a rather loose-growing plant a foot or two 

 high, but there are dwarf and compact forms ; also va- 

 riegated forms. Trop. Amer. B.M. 2.524.— This is the 

 common ageratum of gardeners and florists. It is easily 

 grown from seeds, sown in the border where the plants 

 are to stand, or started in the house or hotbed, if the 

 plants are to be used for bedding, they should be placed 

 a foot or less apart. They thrive in any garden soil and 

 exposure. They bloom all summer ; and if sown in 

 late summer or faU, they give winter bloom under glass. 



The plant sold as A. co}ispin<}<m is an Eupatorium ; 

 and that sold as A. Lasseiyiixii is a CouocUnium.

AGKIMONUA 



AGLAIA {Greek, splendor; from the order and gen- 

 eral appearance). Melidcece. Tender tree from China, 

 with minute, yellow, fragrant fls., said to be used in per- 

 fuming certain teas. Prop, by cuttings. 



odor^ta, Lour. Lvs. alternate, 5-7 pinnate : fls. in axil- 

 lary, branching panicles. Cult, sparingly in Calif. 



AGLAONfiMA {Greek, ?>Wf7/i/^;(rearf). AroUav. About 

 15 species, of trop. Asia and Africa, allied to Arum, 

 Alocasia and Dleffenbachia, and requiring essentially 

 the same treatment as those genera. Evergreen, often 

 beautifully variegated. Aglao- 

 ueraa may be divided, or cut- 

 tings may be taken from 

 plants that become too tall 

 and weak. In either case the 

 cuttings and divisions should 

 be put into the sand-bed pre- 

 vious to potting, to develop 

 new roots. All of the kinds 

 will succeed in fibrous loam 

 enriched with rotted ma- 

 nure, with the addition of 

 a moderate quantity of 

 leaf-mold, sand, and some 

 crushed charcoal. 



Cult, by G. W. Oliver. 



pictum, Kunth. Dwarf : 

 lvs. somewhat unequilateraI,ob 

 long or elliptic, ovate (4-7 in. 

 long and 2-H in. wide), very dark 

 green, blotched with white, the 

 central markings usually ex- 

 tending the whole length of the 

 midrib : spathe white or whit- 

 ish, 1-lHin. long. Sumatra. 

 I.H. 29: 445. 



nebulosum, N. E. Brown.

 (5-8 in. long, l^in. or less 

 wide», more acuminate, the 

 markings rather more broken 

 and not so continuous along the 

 midrib. I.H. 1887:24. A.G. 16: 

 361, and F.E. 7:961, as A. pic- 

 tum. — This and A. pictum are 

 confused in the trade. Both 

 species deserve more attention 

 than they have received in this 

 country. 



costd-tum, Veitch. Very dwarf 

 and compact: lvs. heart-shaped, 

 thick, 3 in. 

 wide, one- 

 third longer

 ceeding5in.

 ivory-white and scattering 

 blotches of white. Holds its 

 tufted lvs. through the win- 

 ter. Moluccas. 



50. Agave maculosa. 



A. commutdtum, Schott.=Seindapsus Cuscuaria. — A. Roe- 

 blimi, Hort., is"a fine decorative plant, with thick, leathery fo-
