regular, and has Ave ribs terminating in 

 five pointed teeth ; the corolla is funnel 

 or bell-shaped ; the stamens (four with the 

 rudiment of a fifth) have divergent an- 

 thers, which are either glabrous or covered 

 with long hairs, and afford excellent cha- 

 racters for distinguishing the different 

 otherwise very similar-looking species; 

 the capsule is linear and flat, its partition 

 placed contrary to the direction of the 

 valves; and its numerous winged seeds 

 are in single rows. [B. S.] 



The same name has been applied to a 

 genus of papilionaceous Leguminosce, con- 

 sist] n g of cli mbing shrubs, with trif oliolate 

 leaves, and axillary flowerstalks bearing 

 numerous tufts of blue flowers. The calyx 

 is bell shaped, two-lipped; the vexillum 

 erect, provided with a membranous ap- 

 pendage on each side at the base ; stamens 

 ten, diadelphous; ovary sessile ; style fili- 

 form ; pod sessile, linear compressed, thick- 

 ened at the sutures, many-seeded— the 

 seeds separated one from the other by 

 transverse cellular partitions. 



The generic name is derived from the 

 Greek stenos 'narrow,' in allusion to the 

 structure of the pods. The species are 

 natives of Tropical America. [M. T. M.] 



STENOMESSON". An amaryllidaceous 

 genus of bulbs, chiefly from Peru. They 

 produce linear or lanceolate leaves, and a 

 solid terete scape, bearing a few or many- 

 flowered umbel of erect or drooping 

 blossoms, which have a slender cylindra- 

 ceous tube constricted in the middle, 

 and subventricose in the upper part; and 

 with a six-cleft regular limb, and a six- 

 toothed coronet bearing stamens between 

 the teeth. The style is filiform, with a 

 clavate dilated apex. The flowers are yel- 

 low orange-coloured or scarlet, and very 

 handsome. [T. M.] 



STENOPETALTTM. A genus of Cruci- 

 ferce from Australia, consisting of herbs 

 with linear leaves, entire orthe lower ones 

 lyrately pinnatifid, and terminal racemes. 

 The pouch is obovate or elliptical, slightly 

 compressed, parallel to the septum, the 

 valves slightly concave ; the seeds nu- 

 merous, with short seed-stalks. [J. T. S.J 



STENORHYNCHUS. A terrestrial genus 

 of orchids belonging to the JS'eottcce. 

 About ten species have been described, 

 inhabitants of Tropical America and the 

 West Indian Islands. They are herbs with 

 fascicled roots, broad radical leaves, spikes 

 densely imbricated with large coloured 

 bracts, and the flowers generally hairy 

 and showy. It differs from Spiranthes, to 

 which it is closely allied, in its large showy 

 flowers and coloured bracts, and the want 

 of calli at the base of the lip : while from 

 Pelexia it differs in its large flowers and 

 bracts, and in the rostelluru being hard 

 and horny, remaining as a rigid spine 

 upon the apex of the stigma after the 

 pollen-masses have fallen away. The name 

 is derived from stenos 'narrow' and 

 rln/nchos ' a beak.' [W. B. H.] 



STEXOSEMIA. A genus of acrostichoid 



ferns of the reticulated series. The two 

 or three known species are dwarf plants 

 with temately divided fronds, having the 

 two pinnse very oblique and bipinnatifid, 

 and bulbiferous in their axils. The fertile 

 fronds are cut up into many irregular 

 narrow segments. The lowermost venules 

 anastomose, so as to form costal areoles, 

 while the ultimate or marginal ones are 

 free. The plants are natives of the Indian 

 Archipelago. [T. M.J 



STENOSIPHON. A genus of Onagracem, 

 in which the tube of the calyx is narrow 

 and long ; the corolla is of four petals, the 

 two posterior largest ; and the stamens 

 eight in number, the four opposite the 

 petals being longest. The only species is 

 a native of Texas, of herbaceous habit, 

 with slender branches ; the leaves alter- 

 nate, very narrow, and rigid ; and the 

 flowers white, in dense spikes. The name 

 is from the Greek stenos 'narrow' and 

 siphon 'a tube,' and refers to the narrow 

 tube of the calyx. [G. D.] 



STENOSIPHONIUM. A genus of Acan- 

 thacece, containing four species of shrubs 

 from India. They have toothed leaves, 

 and axillary and terminal spikes. They 

 differ from Ihiellia in having the calyx 

 divided to the middle, and in the slender 

 tube of the corolla opening upwards into 

 a campanulate limb. [W. C.J 



STENOSTOMUM. A small West Indian 

 genus of Cinchonacece, consisting for the 

 most part of low trees, with elliptical or 

 oblong leaves furnished with deciduous or 

 persistent stipules, and sometimes covered 

 with a sticky resinous exudation on the 

 upper surface; and bearing axillary two- 

 branched flower-spikes, having the flowers 

 (which are small whitish and stalkiess) 

 arranged along the inner sides of the 

 branches, with one also in the fork. It is 

 characterised by the flowers having the 

 short free part or limb of the calyx four 

 or five-toothed or almost entire, and per- 

 sistent on the mature fruit ; by the salver- 

 shaped corolla, with four or five overlap- 

 ping lobes, and with the stamens (which 

 have narrow anthers and very short fila- 

 ments) inserted below its throat, and 

 either entirely included within the tube or 

 half protruded; and by the two to six-celled 

 ovary with a simple style and round-headed 

 stigma, the ovary ultimately forming an 

 unopening fruit, containing a two to six- 

 celled stone, with as many cylindrical 

 seeds. [A. S.J 



STEPHANANDRA. A Japanese shrub, 

 with alternate broadly ovate lobed or cut 

 leaves, and small flowers in loose terminal 

 cymes, forming a genus of Rosacece allied 

 to Spircea, and resembling some of its 

 species in habit. It differs essentially, 

 however, in the ovary being reduced to a 

 single carpel with two pendulous ovules ; 

 and in the fruit, which is a small follicle, 

 with one or two globular albuminous 

 seeds. 



STEPHAjS'OPHYSUM. A genus of
