was not placed near Mimofa, in the firft feaion of that na- 

 tural order. Swartz, Ind. Occ. 9S0, fpeaks of Browne s 

 figure of the flower of Zygia, as exadly like h:s own Mimofa 

 comofa, Prodr. 85 ; but he adds that the plants ar^ different, 

 without any further elucidation of the former. There is no 

 fpecimen of Zji^^ia, amongft the plants in the Linnxan her- 

 barium, colleded by Browne, and fent by Solander to i^n- 

 iiKus. In a manufcript catalogue of Jamaica plants, in Dr. 

 Browne's own hand, given to the writer of this article by 

 A. B. Lambert, efq., Mimofa Zygia ftands between /a^i- 

 folia and Unguis Cati, with this remark, which is not m the 

 author's Hiftory of Jamaica, " folia btjugala, Jvefujeiitacu- 

 lis bipartitis, fnguHs diphyllis." This plant is there called 

 Yoke-wood. In the printed work it is denominated Horfe- 

 wood, or Hoop-wood, the wood being " pretty tough, 

 and fometimes cut for hoops. The (hrub is very common 

 in St. Mary's, growing chiefly in low moid lands ; but is 

 fometimes found in the mountains, where it commonly rifes 

 to the height of ten or twelve feet, or better." Thefe 

 are all the particulars we can gather relative to Browne's 

 Zygia. 



Zygia, in the Injlrumental Mufic of the Ancients, a flute 

 peculiar to weddings, according to Apulcius. (Metam. 

 lib. iv.) The word zygia is a Greek adjeftive, which im- 

 plies nuptial. The zygia was probably a double flute ; for 

 Julius Pollux (Onomaft. lib. iv. c 10.) fays, " there was 

 alfo a flute air for the wedding ; executed on two flutes, one 

 longer than the other." 



Zygia, in Entomology, a genus of infcAs belonging to 

 the order of coleoptera, the charafters of which are, that 

 the antenna are moniliform, the palpi unequal and filiform, 

 the lip elongated and membranaceous, and the jaw uni- 

 dentated. There is one fpecies, viz. 



Oblonga. Found in the Eaft, oblong, red, with head 

 and wing-flieaths cyaneons. 



ZYGIANA, in Ancient Geography, a country of Afia 

 Minor, in Bithynia. Ptolemy. 



ZYGIS, in Botany, the fpecific name of a fpecies of 

 Thymus, (fee that article, n. 9,) fuppofed to be the 

 fi/)i,- of Diofcorides. De Theis, who writes this word 

 |iyi.-, without any authority that we can find, derives it 

 from ifi>"/<K, the hum of bees, which is confirmed, appa- 

 rently without his knowledge, by the modern Greek 

 name of the fame plant, irf/x'51, the delight of bees. Such 

 an appellation is pecuharly fuitable to a plant well known 

 to be highly grateful to thofe infefts, and which is fup- 

 pofed to give its aromatic flavour to the famous honey 

 of mount Hymettus, a fpot where this Thymus abounds. 

 Undoubtedly there are other fpecies of the fame genus, as 

 well as of Thymbra, Salureia, &c., found in the fame neigh- 

 bourhood, which contribute to produce this flavour, in as 

 powerful a degree perhaps as the above. 



Z YGIT.(E, in the Roman Galleys, a term ufed to exprefs 

 thofe rowers in the triremes, or three-rowed galleys, who 

 fat on the fecond row, that is, above the thalamitae, and be- 

 low the thranitae. 



ZYGOMA, Zvycijitt, in Anatomy, a bone of the head, 

 otherwife called os jugale ; or, it is the bony arch under 

 which the temporal mufcle pafles. 



The word is formed from ^fjytvjj.i, I join ; fo that zygo- 

 ma, properly fpeaking, is the junfture of two bones. See 

 Cranium. 



ZYGOMATIC Process of the temporal bone and

becaufe it contributes largely to the formation of the zy- 

 goma. See Cranium. 



ZYGOMATICUS, Major and Minor, mufcles of the 

 face, conncfted to the corner of the mouth. See Deglu- 

 tition. 1 



Zygomaticus is alfo an epithet given to the future that 

 binds the two procelTes of the zygoma together. 



ZYGOPHYLLUM, in Botany, fo named by Linnseus, 

 from ^vyo;, a yoke, and ifuX'.&v, a leaf, each leaf, of mod ot 

 the fpecies, being compofed of a pair of leaflets, yoked, 

 as it were, together, and fomewhat refembling the foliage 

 of the garden bean, Vicia Faba ; whence this genus ob- 

 tained, from Dodonseus and Tournefort, the name of Fa- 

 bago. Hence alfo arofe its Englith appellation of Bean- 

 Caper, given by Gerardc. Fabago was properly deemed 

 inadmiflible, being compounded of another name, though 

 of one no longer in ufe as generic. We may obferve more- 

 over, that it conveys an erroneous idea ; for the plant in 

 queftion does not " bear beans," but leaves, refembling

Gen. Ch. Cal. Perianth inferior, of five ovate, obtufe, 

 concave, ereft leaves. Cor. Petals five, dilated upwards, 

 obtufe, emarginate, rather longer than the calyx. Neftary 

 of ten converging, pointed leaves, or fcales, fometimes di- 

 vided, embracing the germen, each of them attached to 

 one of the filaments near its bafe. Stam. Filaments ten, 

 awl-fhaped, attached to the outfide of the ne£tary, fnorter 

 than the corolla ; anthers oblong, incumbent. Pifl. Ger- 

 men fuperior, oblong, tapering at the bafe ; ftyle awl- 

 fliaped, the length of the ftamens ; ftigir.a fimple. Peric. 

 Caplule oblong, or roundifh, with five angles and five inter- 

 mediate furrows, five cells and five valves, the partitions 

 linear, from the middle of each valve. Seeds feveral, roundiflx 

 kidney-fliaped, iuferted alternately, in two rows, into the 

 middle of the valves. 



Obf. Linnaeus remarks, that the feed-veflel differs in 

 fhape in the different fpecies, and that in feme the flowers 

 are four-cleft and octandrous. Schreber records an obferva- 

 tion of Reichard, merely taken from the Mantijfa of Lin- 

 naeus, that Z album has iivc Jligmas ; but we do not find 

 this to be corred. Our fifteenth fpecies is faid to have five 

 diftina7?y«. 



Eff. Ch. Calyx of five leaves. Petals five. Neftary 

 often fcales, embracing the germen, and bearing the ftamens. 

 Capfule of five cells, fuperior. 



The plants of this genus are, for the moft part, fhrubby, 

 with fimple or twin Laves, (rarely ternate or pinnate,) which 

 are oppofite, moftly ftalked, entire, often foetid, of a thick 

 or fucculent texture, accommodated to the dry and funny 

 fituations where the greater part of the fpecies grow. A 

 very few are found in South America, or Guinea ; the reft 

 are natives of Syria, Arabia, Siberia, and efpecially of 

 fouthern Africa, about the Cape of Good Hope. The 

 Jloiuers are folitary, axillary, yellow, white, or reddifti, often 

 brilliant and rather handfome. The feed- 'vejfel, though an- 

 fwering in general to the above defcription, which is made 

 from Z. Fabago, is varioufly fhaped in the different fpecies, 

 and in fome appears to be lined with a fort of horny elaftic 

 coat, analogous to the tunic of tht feeds, fo remarkable in 

 the genuine Rutacee. Such is the cafe in Z. microphylhtm,
