orange-coloured and tubular ; stamens five, 

 concealed within the corolla: ovary tive- 

 celled, surmounted by an epigynous disk ; 

 style simple ; stigma undivided; fruit suc- 

 culent, five-celled, with numerous seeds in 

 each compartment. H. -patens and other 

 species are in cultivation as stove plants, 

 and have handsome flowers. [M. T. M.] 



HAMELINIA. A genus founded by 

 Richard on imperfect female specimens of 

 Astelia Banksii or Solandri, and conse- 

 quently not adopted by other botanists 

 who have had better opportunities of ex- 

 amining these species. [J. T. S.] 



HAMI (adj. HAMATE, HAMOSE). 

 Hooks, hairs, or small spines which are 

 hooked at the point. 



HAMILTONTA. Indian shrubs with 

 fragrant flowers, constituting a genus of 

 Cinchonacece. The flowers have a funnel- 

 shaped corolla with a long tube and a limb 

 divided into five oblong lobes; stamens 

 five, concealed within the tube of the 

 corolla; ovary inferior, five-celled; style 

 simple; stigma with five acute segments ; 

 capsule one-celled, with five one-seeded 

 stones. R. suaveolens and H. scabra are 

 cultivated in stoves, for the sake of their 

 white fragrant flowers. [M. T. MJ 



HAMMERSEDGE. Carex hirta. 



HAMPEA. A genus of the Bombax 

 family peculiar in the nature of its fruits, 

 which are rusty-coloured capsules of the 

 size of a cherry, bursting into two or three 

 portions, each portion containing a single 

 seed with a fleshy aril at its base. There 

 are but two species, one a Mexican bush, 

 the other a tree of New Grenada. Both 

 have alternate long-stalked leaves, like 

 those of the common poplar but larger; 

 and bear on the same tree sterile and fer- 

 tile white flowers, about half an inch 

 across, solitai-y or two to three together in 

 the axils of the leaves. They have a bell- 

 shaped calyx with an entire border, five 

 narrow petals slightly united at the base, 

 and numerous stamens of unequal length ; 

 or, in the fertile flowers, a few barren sta- 

 mens united into a ring inserted on the 

 base of the petals, and surrounding the 

 ovary. [A. A. B.] 



HAMULOSE. Covered with little hooks. 



HAMULUS. A kind of hooked bristle 

 found in the flower of Uncinia. Schleiden 

 regards it as a third glume, free from the 

 two which form the flask. 



HANBURIA mexicana is the sole re- 

 presentative of a genus of Cucurbitacece 

 peculiar to the mountains near Cordoba, 

 Mexico, and named after Daniel Hanbury, 

 a distinguished London pharmacologist. 

 It is a climber, having a pentagonal stem, 

 furnished with simple tendrils, cordate 

 leaves, axillary or terminal white and 

 monoecious flowers, the males being ar- 

 ranged in racemes, whilst the females are 

 solitary in the axils of the leaves. The 

 calyx and corolla are bell-shaped ; the 

 ovary is four-celled, each cell containing 



one seed ; and the fruit is oval, covered 

 with long spines, and bursting open like 

 that of Momordica, propelling the flat 

 circular seeds (resembling those of Feuil- 

 lea) to some distance. The Mexican squir- 

 rels are fond of eating the seeds, but, being 

 unable to open a fruit so well protected by 

 spines, they wait in the morning for the 

 time when the first rays of the sun fall 

 upon the ripe ones and cause them to burst. 

 The Mexicans term the plant Chayotilla, 

 from the close resemblance of its fruit to 

 that of the cayotl or chayota (Sechium 

 edule). [B. S.J 



HANCHINOL. The Mexican name for 



Heimia salicifolia. 



HANCORNIA. A small genus of Apocy- 

 nacece, found in Brazil, and forming small 

 trees or shrubs, abounding in all parts with 

 a viscid milky juice, which is one of the 

 sources of caoutchouc. They have entire 

 opposite leaves, marked with pellucid 

 veins; and sweet-smelling flowers resem- 

 bling those of the jasmine. The calyx is 

 five-parted, without glands; the corolla 

 has a long narrow tube, hairy inside, and 

 the Ave segments spread out when the 

 flower opens, but are previously rolled 

 round each other; the five stamens are 

 inserted into the middle of the tube ; and 

 the ovary is divided into two cells, and has 

 a long thread-like smooth style, and a 

 forked stigma. The fruit is a large globu- 

 lar or pear-shaped fleshy berry, exuding a 

 milky juice when wounded, and contain- 

 ing numerous hard seeds lying in pulp. 



E, speciosa is a small tree somewhat re- 

 sembling the weeping-birch in habit, with 

 drooping branches, and small oblong 

 leaves, sharp at the base, and rounded but 

 with a short point at the apex. It is called 

 Mangaba or Mangava, and bears a most deli- 

 cious fruit, which is a great favourite with 

 the Brazilians, but is only fit to eat when 

 perfectly ripe, or after being kept for a 

 short time. It is about the size of a plum, 

 of a yellow colour marked with red spots or 

 streaks. The milky juice of the tree, when 

 exposed to the air, hardens into a kind of 

 caoutchouc. [A. SJ 



HAND-PLANT. Clieirostemon plata- 

 iwides. 



HANNEBANNE. (Fr.) Hyoscyamus 

 niger. 



HANNOA. The name of a Senegambian 

 tree, forming a genus of Simarubacece. 

 The flowers are unisexual, the males with 

 the sepals combined into a somewhat 

 two-lipped calyx, and the rudimentary 

 ovaries concealed within a large disk. The 

 female flowers are not known. [M. T. MJ 



HAPLANTHUS. A genus of Acan- 

 thaceoE, containing three species, natives 

 of India. They are erect branching herbs, 

 with ovate petiolate leaves, and flowers in 

 few-flowered terminal racemes furnished 

 with small bracts. The calyx is five- 

 parted, the corolla funnel-shaped, with an 

 unequally five-cleft limb; the two stamens
