AMH^BSTIA (Countess Amherst and her daughter, 

 Lady Amherst, promoters of botany in India). Legu- 

 mindsce. One of the noblest of flowering trees, native 

 to India, where it reaches a height of 40 ft. and more. 

 Gaudy red fls. 8 in. long, with wide-spreading petals, the 

 upper ones gold-tipped, and colored petal-like bracts, in 

 long, hanging racemes : Ivs. pinnate, nearly 3 ft. long. 

 The tree first flowered in Eng. in 1849. It requires hot- 

 house treatment. The fls. last only 2 or 3 days. Demands 

 rich, loamy soil, and abundant moisture during the grow- 

 ing season, after which the wood must be ripened firm.

AMIANTHIUM. See Zygadenits. 



AMMdBIUU (Greek, living in sand). Comp6sitce. 

 Hardy herb, cult, as an everlasting or immortelle. Florets 

 Perfect, yellow, surrounded by a dry, silvery white invo- 

 lucre, and subtended by chaffy scales; pappus of 2 bris- 

 tles and 2 teeth. Commonly treated as an annual, but 

 seeds are sometimes sown in Sept., and the plant treated 

 as a biennial. Of easiest culture, the seeds being sown 

 where the plants are to grow. In the N., sow seeds in 

 spring. Cut the fls. before they are fully expanded, and 

 hang in a dry, shady place. They will then remain white. 



aUtum, R. Br. Three ft. or less high, erect and 

 branchy, white-cottony, the branches broadly winged : 

 early root-lvs. ovate at the ends and long-tapering be- 

 low (Javelin-shaped); st.-lvs. linear or linear-lanceolate, 

 entire or nearly so : heads 1-2 in. across, the involucre 

 becoming pearly white. Australia. A large-headed form 

 is var. grandi£16run. L. h. B. 



AMMOCHABIS (ammos, sand; cftaWs, beauty). Ama- 

 rylUddeem. Greenhouse bulb from Cape of Good Hope. 

 J. G. Baker, Amaryllidese, p. 96. For cult., see Bulbs. 



ialc&ta, Herb. Bulb ovoid, sometimes 6-9 in. in diam., 

 with brown tunics : Ivs. 1-2 ft. long, 1 in. wide, strap- 

 shaped, spreading, produced before the Ivs. : fls. 20-40, 

 in an umbel, bright red, fragrant. Winter. Probably 

 the fruit figured in B.M. 1443 is that of a Brunsvigia, 

 mismatched with the flowers. 



Ammocharis falcata requires rich, loamy soil. It 

 starts to grow in the spring. Give plenty of water during 

 growing season in summer. It can be cultivated out-of- 

 doors. When perfected and finished in autumn, the bulb 

 can be put under the greenhouse bench ; keep moder- 

 ately dry in sand or earth ; can be potted in January, 

 after which it will soon throw out its fine, fragrant 

 blooms. Cult, by H. A. Siebrecht.

AMOBFHOFHALLUS (Greek-made name). Aroldeai. 

 Giant aroids, from the eastern tropics, grown as curiosi- 

 ties in hothouses. Spathe (or "flower") springing from 

 the great bulb-like tuber in advance of the Ivs., the latter 

 usually pedately compound : differs from Arum and re- 

 lated genera by technical characters. Monogr. by Engler 

 in De Candolle's Monographise Phanerogamarum, vol. 2, 

 1879. 



Amorphophalluses are propagated by offsets of the 

 tubers. Towards the end of March the plants should be 

 taken from their winter quarters and placed on the 

 stages of a moderately warm greenhouse and kept moist, 

 where, if the tubers are strong enough, they will soon 

 flower. The leaves begin to grow immediately after the 

 flowering season. Towards the end of May they should 

 be planted out in the open ground, or they may be used 

 in subtropical bedding. Plants .should be lifted in the 

 fall, before frost, and potted in any good, rich soil, and 

 placed in a warm greenhouse to ripen off the leaves, after 

 which they may be stored away under the greenhouse 

 stages, or any convenient place where the temperature 

 does not fall below 50°, giving just sufficient moisture to 

 keep the tubers from shriveling.
