leaves and small flowers, with salver- 

 shaped corollas, and eight or ten ovaries 

 variously united. [J. T. S.] 



DOLICHANDRA. A small genus of 

 Biijri miiacece, inhabiting extratropical parts 

 of Brazil, and remarkable as the only 

 known climber of the order having a cap- 

 sule the partition of which runs in a con- 

 trary direction to that of the valves. In 

 habit it much resembles Macfadyena, the 

 branches being climbing, the leaves either 

 trifoliate or conjugate, and furnished 

 with tendrils, and the flowers in the axils 

 of the leaves; the calyx is spathaceous; 

 the corolla is long and tubular, whilst the 

 stamens (four in number with the rudi- 

 ment of a fifth), as well as the stigma, pro- 

 ject beyond the corolla. The typical spe- 

 cies is B. cynmiclioides. [B. S.] 



DOLICHANDRONE. A small genus of 

 bignoniaceous trees, inhabiting tropical 

 Asia and Australia. Their leaves are either 

 simple or impari-pinnate, and the leaflets 

 either ovate, lanceolate, or, in B. flliformis 

 of New Holland, reduced to very narrow 

 linear bodies. The flowers are white and 

 arranged in panicles ; the calyx is spatha- 

 ceous, and the corolla has a tube twice or 

 thrice the length of the calyx; the sta- 

 mens are four in number, with the rudi- 

 ment of a fifth ; the fruit is a flat cap- 

 sule opening at the margin, but being divi- 

 ded by a partition, which runs contrary 

 to the direction of the valves. Some of the 

 Asiatic species yield timber. [B. S.] f 



DOLICHOS. A genus of leguminous 

 plants, consisting of herbaceous or shrubby 

 plants, 'which for the most part have twin- 

 ing stems. Between sixty and seven ty 

 species are known, and are found equally 

 distributed throughout the tropical and 

 temperate regions of Asia, Africa, and 

 America. The plants, formerly called D. 

 Lablab {Lablab vulgaris), B. sinensis (Vigna 

 sinensis), B. bulbosus (Pacliyrhizus angula- 

 tus), B. Catjang {Vigna Catjang), all produce 

 edible legumes and pulses. The species of 

 Bolichos have trifoliate leaves ; and their 

 flowers are produced, either solitary or in 

 racemes, from the bases of the leaves. 

 The pods are generally more or less flat- 

 tened, and neither winged nor prominently 

 nerved. 



B. sesquipedalis is a native of the West 

 Indies and tropical South America, but is 

 cultivated in warm sheltered places in 

 France, and some parts of the south of 

 Europe. The French call it Bolic asperge. 

 It has smooth twining stems, six or eight 

 feet in height, with large egg-shaped 

 pointed leaflets, and yellowish-green 

 flowers. Its pods are from a foot to a foot 

 and a half long, cylindrical and pendulous, 

 and of a shining light-green colour, con- 

 taining from seven to ten kidney-shaped 

 seeds. The young or green pods of this 

 plant are cooked and used as a table vege- j 

 table, and, being without the tough parch- I 

 ment-like skin of the common pea-pod, I 

 they form an excellent dish. B. tuberosus, \ 

 a native of Martinique, has a fleshy tu- 1 



berous root, which the inhabitants cook 

 as an article of food, and they also vise the 

 pulse for the same purpose. It has a 

 shrubby stem, with twining branches, and 

 leaves with l-oundish-pointed leaflets. B. 

 imifloriis is an annual plant having an 

 erect stem and twining branches, with 

 leaves composed of three egg-shaped leaf- 

 lets, and yellow flowers, which produce 

 narrow flat pods curved something like a 

 reaper's sickle, and covered with soft hairs. 

 This plant is a native of the East Indies, 

 where it is grown for food under the name 

 of Horse Gram. [A. S.] 



DOLIOCARPUS. A small genus of dille- 

 niads, consisting of about half a-dozen 

 species, nearly all of which are climbing 

 shrubs, inhabitants of tropical South Ame- 

 rica. It is closely allied to Belima, but the 

 leaves are not rough, and the flowers are 

 produced from the sides instead of the 

 ends of the branches : besides which, the 

 fruit is pulpy and does not burst open 

 when ripe. B. Calinea is a climbing shrub 

 with woody stems, having oblong pointed 

 leaves, and small white flowers collected 

 into dense heads, a portion only perfect, 

 the rest being male or female. The fruit 

 is a small fleshy shining berry. [A. SJ 



DOLOMIiEA. A genus of Composites, 

 nearly related to Saussurea, but differing 

 in the pappus-hairs being rough instead of 

 feathery. B. macrocephala,the only known 

 species, is a perennial stemless herb found 

 at elevations of 10,000 to 13,000 feet in 

 N. W. India ; it has pinnately parted much- 

 lobed leaves clothed with white down be- 

 neath, while the centre of the plant is 

 occupied by a cluster of shortly-stalked 

 flower-heads, each an inch or more in 

 length, and furnished with an involucre 

 of numerous lance-shaped scales, which 

 enclose many purplish tubulous florets. 

 According to Royle, it is used by the 

 inhabitants of the hills in their religi- 

 ous ceremonies, and is called by them 

 Googlan. [A. A. BJ 



DOMBA-OIL. A fragrant oil obtained 

 from the seeds of Calophyllum Inopltyllum. 



DOMBEYACE^E. A tribe of plants in- 

 cluded in the natural order Byttneriacem. 

 The petals are flat ; stamens fifteen to 

 forty, united at their base, usually some 

 of them sterile. Ovary with five or many 

 cells, having two or more ovules in 

 each. Fruit a capsule ; embryo within 

 fleshy albumen. Trees or shrubs growing 

 in tropical regions of the Old World. 

 In this tribe are included the genera, 

 Pentapetes, Brotera, Bombeya, Me'lhauia, 

 Astrapcea, and a.few others. [J. H. B.] 



DOMBEYA. A genus of handsome 

 African shrubs or small trees of the Bytt- 

 neria family, a goodly number of them 

 cultivated in plant stoves for the sake of 

 their handsome foliage and flowers. They 

 are found in the greatest number in Mada- 

 gascar and Mauritius, and extend as far 

 north as Abyssinia. The leaves are often 

 like those of the maple or the plane, but
