sessile ; fruit -with a thick rind, inter j 

 nallj- fleshy. S. cleomoides, a native of 

 Caraccas, is in cultivation as a hothouse 

 shrub. [M. T. M.] 



STERXBERGIA. A genus of Amarylli- 

 dacece, consisting of dwarf bulbous plants 

 found in Eastern and Central Europe, and 

 having linear-lorate leaves, often later than 

 the flowers, and solid scapes bearing a 

 single erect flower of a funnel-like form, 

 with a straight tube widened upwards, 

 and a six-parted semipatent limb ; the six 

 stamens are inserted unequally in the 

 throat ; and the style is filiform, with a 

 1 three-lobed stigma. S. lutea is a well- 

 known garden flower, blooming at the end 

 of summer, and looking like a large yellow 

 autumnal crocus. [T. M.] 



STErDELIA. A genus of Paronychia- 

 cew, the same as Adenogramma, which is 

 the name more generally adopted. 



STEVEXIA. A genus of Crnclferce from 

 Siberia, an annual covered with grey stel- 

 late pubescence, having an ascending 

 branched stem, with oblong linear entire 

 leaves, and corymbose racemes of white 

 flowers; calyx with the two outer sepals 

 bulging at the base; pod oblong, con- 

 stricted between the seeds, with plane 

 valves; seeds two to four in each cell, 

 ovate-compressed, immarginate. [J. T. S.] 



STEYEXSOXIA. Verschaffeltia. 



STEVIA. Esteve was a professor of 

 botany at Valencia. The present genus of 

 plants named in honour of him, consists of 

 numerous species of herbaceous or some- 

 what shrubby Composite?, natives for the 

 most part of Tropical America. The leaves 

 are entire or three-cleft, occasionally whorl- 

 ed, but usually opposite ; and the heads of 

 flowers are arranged in dense corymbs; 

 the involucre is cylindrical, and consists of 

 a few acuminate scales ; receptacle naked ; 

 corollas all tubular, white pink or purple ; 

 stigmas cylindrical, club-shaped ; achenes 

 striated ; pappus scaly, the scales some- 

 times awned. Numerous species are culti- 

 vated as bedding or border plants in this 

 country. [M. T. MJ 



STICHIDIA. A name given to the pod- 

 like processes containing tetraspores in 

 some of the rose-spored Algce, as in Dasya 

 and Odonthalia. [M. J. B.] 



STICHUS. In Greek compounds = a row 

 of anything. 



STICKADORE. Lavandula Stcechas. 



STICKSEED. Echinospermum. 



STICTA. A fine genus of foliaceous 

 coriaceous or membranaceous, velvety 

 tornentose or more rarely smooth lichens, 

 belonging to the same group as Parmelia, 

 with the habit of the ground liverworts 

 (Peltidece), and remarkable for the round 

 white or yellow pits on the under-side, 

 which extend to the medullary stratum, 

 and have been called cyphellse. Several 

 of the species are very large, and even our 

 own ,S'. glomulifera is sometimes three 



feet across. The genus is by no means 

 confined to temperate regions, some of the 

 finest occurring in warm countries. ,5. 

 pulmonariais a popular remedy in diseases 



Sticta pulmonaria. 



of the lungs, under the names of Lung- 

 wort, Hazel Rag, Hazel Crottles, or Rags. 

 S. sylvatica and fuliginosa are remarkable 

 for their fetid fish-like smell. [M. J. B.] 

 1 STICTOPHYLLUM. A genus of Com- 

 posite?, comprising an herbaceous plant, 

 native of Northern India, with linear- 

 oblong sessile leaves, revolute at the mar- 

 gins, and with a thick midrib. The flowers 

 are like those of a Serratula, from which 

 and other allied genera the present one 

 may be distinguished by its persistent 

 feathery pappus of distinct hairs ; and by 

 the scales of the involucre, which are de- 

 stitute of any appendage. [M. T. M J 



STIFFTIA. A genus of Brazilian arbo- 

 rescent Composite?, of the mutisiaceous 

 group, distinguished by its closely-imbri- 

 cated involucre, of which the outer scales 

 are roundish ovate, and the inner linear ; its 

 naked alveolate receptacle; its glabrous 

 regular florets, with five circinately re- 

 curved lobes; its much exserted caudate 

 anthers; its short-armed bifid style; and 

 its glabrous elongated achenes, and mul- 

 tiserial pappus of linear serrated hairs. 

 S. chrysantha is a handsome species, with 

 lanceolate acuminate leaves, and terminal 

 heads of showy orange-coloured flowers, 

 issuing from amongst the long coloured 

 pappus-hairs. It is now more commonly 

 referred to Augusta. [T. MJ 



STIGMA (pi. STIGMATA). That surface 

 of a style, usually at its extremity, to 

 which the pollen adheres when it fertilises 

 the ovules. 



STTGMAPHYLLON (sometimes written 

 STIGMATOPHYLLON). This name is ex- 

 pressive of the leafy nature of the stigmas 

 in the flowers of the genus of Malpighiacem 

 to which it is applied. The species are tropi- 

 cal American shrubs, for the most part of 

 climbing habit, the root usually tuberous ; 

 inflorescence umbel-like, the pedicels usu- 

 ally thickened at the top ; calyx five-parted, 

 the four outer segments with two glands
