XLIV. ESCALLONIE^. 



Escallonie-e, R. Broun in Franklin's Voyage, 766. (1824.) [Saxifragaceje. § Escallonica?. 



Dec. Prod. 4. 2. (1830.)] 



Diagnosis. Polypetalous dicotyledons, with definite perigynous stamens, 

 concrete carpella, an inferior ovarium of several cells with indefinite ovula, 5 

 sepals, and petals cohering in a tube. 



Anomalies. 



Essential Character. — Calyx superior, 5-toothed. Corolla consisting of 5 petals, alternate 

 with the segments of the calyx, from within which they arise, forming- by their cohesion a tube, 

 but finally separating- from eacli other ; aestivation imbricated. Stamens arising from the ca- 

 lyx, alternate with the petals; anthers bursting longitudinally. Disk conical, epigynous, 

 plaited, surrounding the base of the style. Ovarium inferior, 2-celled, with two large poly- 

 spermous placentas in the axis; style simple ; stigma 2-lobed, Fruit capsular, 2-celled, sur- 

 mounted by the persistent style and calyx, splitting by the separation of the cells at their base. 

 Seeds very numerous and minute; with a transparent membranous inteeument ; embryo mi- 

 nute, in the apex of oily albumen, its radicle at the opposite extremity of the hilum.— Shrubs 

 with alternate, toothed, resinously glandular, exstipulate leaves, and axillary conspicuous 



Affinities. Distinguished from Grossulaceae by the cohering petals, and 

 by the radicle of the embryo being at the extremity most remote from the hilum ; 

 the albumen t^also oily, not horny, and the placentae are not parietal. From 

 Philadelpheaa they are known by their glandular leaves and minute embryo ; 

 from Vaccmieae by the final separation of the petals, and by the anthers. 



Geography. All found in the temperate parts of South America, particu- 

 larly Chile. 



Properties. Unknown. Handsome shrubs, with evergreen leaves. 



Example. Escallonia. 



XLV. GROSSULACE.E. The Currant Tribe. .

 2. 897. (1815) ; Lindl. Synops. 106. (1829.) 



Diagnosis. Polypetalous dicotyledons, with 5 perigynous fertile stamens, 

 concrete carpella, an inferior ovarium with one cell and parietal placentae, bac- 

 cate fruit, and distinct petals and sepals. 



Anomalies. 



Essential Character. — Calyx superior, 4- or 5-parted, regular , coloured. Petals 5, minute, 

 inserted in the throat of the calyx. Stamens 5, inserted alternately with the petals, very short. 

 Ovarium 1 -celled, with 2 opposite parietal placentas ; ovules numerous ; style 2-3-4-cleft. Berry 

 crowned with the remains of the flower, 1-celled; the cell filled with pulp. Seeds numerous,
