THE genus Getzia was first described by Wydler in 1830, when he gave a drawing of 
the typieal species, founded on a plant discovered by him in Puerto Rico in 1828, which 
he referred to Hbenacee (Linn. v. 423, tab. 8). Espadea was established and figured by : 
Richard in 1838 (Fl. Cub. ii. 147, tab. 65), the typical species having been brought from 
Cuba in 1835 by Ramon de la Sagra. Although classed by Richard in Verbenacee, it does 
not belong to that family, as shown by M. Bocquillon (Adans. iii. 262), who, however, 
- was unable to determine its true position. The plants of these genera have a common 
resemblance to Chrysophyllum, having bright, coriaceous, alternate leaves, with closely 
parallel nerves, as in that genus; their inflorescence is extraaxillary, either on solitary 
. pedicels or in short 2-3-flowered racemes. The calyx in Getzia is globosely tubular, with 
six lanceolate erect segments, and is fixed upon a broad torus; in Æspadea it is tubular, 
with four, five, or six short, erect teeth, with a valvate æstivation, the tube being par- 
tially adnate to a large pulvinate disk, above which it is free. The corolla in Getzia is 
somewhat hypocrateriform, narrow and hexagonal at its base, soon becoming gradually 
enlarged into a funnel shape, with a regular mouth, surmounted by a border of six equal, 
sublanceolate, suddenly reflected segments, valvate in «estivation; in Espadea it is much 
shorter, infundibuliform, curving outwardly, and swelling into an oblique mouth, with a 
border of four, five, or six short, erect, acute teeth, the posterior tooth being a trifle 
larger, their sestivation being also valvate. The stamens in Getzia are six in number, 
alternate with the lobes of the corolla; their long filaments are fixed near the base of 
the tube, equal in length, straight, erect, distinct, exserted as far as the extremity of the 
segments; in Espadea there are from four to six stamens, alternate with the segments, 
and fixed near the base of the tube, the filaments, somewhat unequal in length, all con- 
verge to, and press against, the posterior segment, thence curve over the centre, extending 
considerably beyond the segments. The hypogynous disk in Getzia, on which the ovary 
is seated, is flat, broadish, and hexagonal; in Æspadea it is tall, broad, pulvinate, and 
fleshy, partially adnate to the calyx, free above, slightly hollow in its summit, with its 
raised margin swollen into five or six rounded fleshy lobes, which are sometimes expanded 
into as many nectariferous, long, acuminate, connivent appendagesı The ovary in 
Getzia is a depressed cone, smaller than the disk on which it is seated, and thickly 
pilose ; it is two-celled, each cell with one or two appended (?) ovules, according to Wydler : 
in Espadea it is similar in form, tomentose, much smaller than the disk, in which it is 
partially imbedded ; it is two-celled, the cells being antical and postical, each containing 
two small globular collateral ovules fixed in the basal angle.
