200 Mr. J. Miers on the Ehretiaceae. 



take, reversed its position, he was quite correct in stating that 

 the embryo is enclosed in a rather thick fleshy albumen, not- 

 withstanding that Prof. A. De Candolle mentions that he had 

 been unable to find it. The calyx and corolla resemble those 

 of Crematomia, only that the lobes of the border in Bourreria 

 are simple, not auriculated ; the style is more shortly bifid ; 

 the ovary has the placentation of Rhabdia. 



Bourreria, Browne; — Beurreria, Jacq. ; — Ehretise sect., DC. 

 — Calyx ad medium tubulosus, coriaceus, superne in lobos 5 

 (rarius 6) acutos divisus, marginibus crassis, tomentosis, 

 a3stivatione valvatis-, firme adhaerentibus, demum solutis, vel 

 interdum false 2-3-lobus, persistens. Corolla gamopetala, 

 tubo calyce paulo longiore, limbi laciniis 5 (rarius 6),oblongis 

 vel rotundatis, patentibus, tubo paulo longioribus, ajstiva- 

 tione valde imbricatis. Stamina 5 (raro 6), alterna, longius- 

 cule exserta aut vix exclusa; Jilamenta subulata, carnosula, 

 medio tubi vel sub fauce afhxa, sajpe cum costis totidem 

 decurrentibus continua ; antherce oblongre, 2-lobee, lobis 

 coriaceis, sa?pe rugulosis, imo a medio divergentibus, superne 

 collateraliter adnatis, utrinque rima longitudinali nivea late- 

 raliter dehiscentibus, sinu dorsali ad filamentum breviter cur- 

 vatum versatiliter affixaj : pollen globosum, tela tartarea in- 

 termixtum. Ovarium oblongum, striatum, disco parvo suf- 

 fultum, semiseptis e parietibus 2 oppositis intergerivis, mox 

 in crura magna utrinque divaricatim recurvis, septa 2 pa- 

 rallela subincompleta efformantibus, marginibus ovulum 

 singulatim amplectentibus, hinc pseudo-4-loculare, 4-ovu- 

 latum : columella compressa, membranacea, septis parallela, 

 axem sistens et fibros nutritorios intra loculos emittens. Stylus

 ramis stigmate peltato singulatim clavatis. Driqja carnosa, 

 globosa, 4-pyrena ; pyrenai intus angulataj, extus convexa?, 

 bigeminatim per paria materiei placentari laxe adhasrentes, 

 dorso oblique spongioso-cellulosas et reticulato-favosa?, aliter 

 osseas, 1-loculares, singulatim latere unico (invicem dexti'o et 

 sinistro) locello spurio infossatas, loculo vero circum spurium 

 paulo curvato, 1-spermo. Semen loculum implens, cylin- 

 dricum, teres, paulo curvatum, juxta locellum spurium 

 jnmcto medio appensum : integumenta tenuia, raphe lineari 

 ab hilo ad chalazam basalem descendente notata : embryo in 

 albumini subamplo carnoso semianatropus et paulo cur- 

 vatus, radicida tereti, supera, cotyledonibus ajquilatis, sub- 

 compressis, hilo parallelis, aequilonga.
