HAMELIA (Henry Louis Duhamel du Monceau, 

 1700-1782, prominent French botanical author). Ru- 

 biacese. Ornamental woody plants grown chiefly for 

 their handsome scarlet or yellow flowers and for the 

 attractive black or purple berries. 



Evergreen shrubs with terete branches: Ivs. mem- 

 branous, opposite or sometimes in whorls, petioled, 

 entire, with interpetiolar stipules: fls. short-stalked or 

 sessile in terminal forking cymes; sepals 5, upright; 

 corolla tubular or bell-shaped, 5-ribbed, contracted at 

 the base, limb with 5 short lobes; stamens 5, with the 

 filaments connate at the base and inserted above the 

 base of the tube ; ovary inferior, 5-celled ; style slender 

 with spindle-shaped stigma : fr. a small ovoid or globu- 

 lar berry with numerous minute seeds. About 13 

 species, by some reduced to 6, in Trop. and Subtrop. 

 Amer. 



These are upright shrubs with herbaceous shoots, 

 rather large, generally ovate-oblong acute leaves and 

 yellow or scarlet flowers in terminal clusters followed 

 by small black or purple berries. They can be culti- 

 vated outdoors in subtropical and tropical regions only. 

 Propagation is by seeds and by cuttings of half-ripened 

 wood in early summer under glass. 



Of the best-known species much prized in Florida 



and recommended for northern conservatories under the 

 name of "scarlet bush," E. N. Reasoner writes: 



"Hamelia patens, a native of the West Indies and 

 Southern Florida, along the coast, a beautiful and 

 almost unknown plant, should become a favorite in 

 greenhouse culture. The leaves have a purplish hue at 

 some seasons of the year, and the flowers are of a bright 

 orange-red color. In Florida it must surely become a 

 favorite for open-air planting, as it is there rarely 

 killed down by frost, and when it is it sprouts up readily 

 from the root, and blooms the following summer. It is 

 in bloom for many months, and without doubt could 

 be forced at any season. With age it becomes a woody 

 shrub, 5 to 12 feet in height. The flowers are succeeded 

 by handsome black berries, which are retained a long 

 while." 



A. Plant glabrous or minutely pubescent. 



patens, Jacq. Shrub, to 12 ft. : Ivs. opposite or usually 

 in whorls of 3, elliptic-ovate to oblong, acute or acumi- 

 nate at both ends, minutely pubescent or glabrous, 

 3-6 in. long; petiole Yr-^-Yi i n - long: infl. 2-5 in. across; 

 sepals triangular, short; corolla with narrowly cylindric 

 tube about %in. long, scarlet-orange: fr. ovoid, black, 

 Kin. long. Fla. to Brazil. B.M. 2533. 



ventricdsa, Swartz. Shrub or small tree: Ivs. usually 

 in whorls of 3, rarely 4, oblong-lanceolate, acuminate, 

 glabrous, 3-5 in. long: fls. yellow, about 1^ in. long, 

 tubular-campanulate, constricted above the base in a 

 terminal few-fld. infl.: fr. ovoid. W. Indies. B.M. 

 1894. B.R. 1195. The similar H. chrysdntha, Swartz 

 (L. B.C. 11:1098) has smaller fls. and smaller more 

 obovate Ivs. 



AA. Plant hirsute. 



sphaerocarpa, Ruiz & Pav. Shrub, to 12 ft.: Ivs. 

 usually in whorls of 3, oblong, acute, undulate, hirsute 

 on both sides, 3-4 in. long: fls. in large terminal cymes, 

 orange-yellow, tubular, about 1 hi. long: fr. subglo- 

 bose, hirsute, purplish black. Peru.

HAPLOCARPHA (probably from Greek for single 

 chaff, in reference to the 1 -rowed chaffy pappus). 

 Composite. Stemless perennials with a woody rhizome: 

 radical Ivs. short-petioled, entire or lyrato-pinnatifid, 

 white-tomentose beneath: scapes 1-headed, longer than 

 Ivs.: fr. 3-5-ribbed, provided at base with tufts of 

 hairs, naked or hairy above, with a crown of small, 

 pointed pappus-scales. Four or five species from the 

 Cape region. H. scapdsa, Harv., resembles an acaules- 

 cent species of Arctotis: Ivs. lanceolate to elliptic, 

 3-9 in. long, green above, white-woolly beneath: 

 peduncles many times longer than Ivs., bearing a soli- 

 tary clear yellow fl.-head, 1^-2^ in. across. G.C. III.

 hardy N. L. H. B. 



HAPLOPAPPUS: Aplopappus. 

 HAPLOPHfLLUM: Ruta. 



HARDENBERGIA (after Franziska, Countess of 

 Hardenberg, sister of Baron Huegel, a well-known 

 traveler.) Leguminosse. Vines, grown chiefly for their 

 handsome flowers. 



Twining herbs or subshrubs: Ivs. pinnate with small 

 stipules; Bts. 3 or 5, sometimes reduced to 1, entire, 

 with stipels: fls. papilionaceous, small, on long racemes, 

 ranging from white through pink and rosy purple to 

 violet-blue, often with 1 or 2 green or yellowish spots 

 on the standard; calyx 2-lipped, the upper 2 teeth con- 

 nate; standard orbicular, with inflexed auricles; keel 

 obtuse, shorter than wings; ovary sessile; style short 

 and thick: pod linear, flat or turgid, with several 

 strophiolate seeds. Three species in Austral, often 

 referred to Kennedya, which has larger and differently 

 colored fls. solitary or in short racemes, with the keel 

 usually about as long as the wing. The two species in
