the wliigs. Placentas S^ eacli bearing a single laterally-attached ovule. After 

 flowering; the ovary tux'ns down into the calyx, enlarges very obliquely, the 3 

 wings forming 2 small points on one side near the base. Fruit dry, inde- 

 hiscent, with a thin pericarp. Seed solitary, reniform, with a hard, rough, 

 almost rauricate testa. Embryo involute, as in most Capparidem. — Shrub oi* 

 nndershrub, with opposite leaves and axillary flowers. 



This curious genus consists of only a single species peculiar to Australia. 



. 1. E. calceoliflora, Z MaelL Iragm, ii. 3, i. 11. A prostrate shrub or 

 nndershrub, harshly pubescent, resembling in habit some species oi Scavoluy 

 and assuming a yellowish hue when dry. Leaves mostly opposite or nearly 

 so, lanceolate or elliptical, acute, mostly 1 to 1^ in. long, narrowed into a 

 short petiole, wavy on the edges, and very harsli. Stipulary spines very mi- 

 nute, often wanting. -Flowers on very short axillary pedicels. Calyx about 

 3 lines long, rather herbaceous, divided to about the middle into 5 brond lobes. 

 Corolla about twice as long, broadly oblong, pubescent. Torus about 4 lines 

 long, pubescent on the thin edges, nearly glabrous along the thickened centi'e. 

 Pericai-p glabrous, 3 or 4 lines broad.

Sepals 4, free, the 2 outer ones valvate in the bud. Petals 4, 3, or none, 

 clawed. Torus elonrated, bearin:]!: at the base on one side a tubular, erect 

 appendage. Stamens 4 to 8, inserted on the summit of the torus. Ovary on 

 a long stalk within the stamens, 1 -celled; pbicentas 3 or 4, with many 

 ovidcs in 3 rows. Stigma small, ses^^ilc. Berry cylindrical. Seeds nearly 

 globular ; cotyledons convolute. — Shrubs, unarmed or prickly. Leaves 

 simple, or in species not Australian 3-folioIate or wanting. Flowers axillarj^ 

 or in terminal racemes or corymbs. 



The gen«9 extends over Africa auJ tropical Asia ; the only Australian species is also iH

 slender claws longer than the calyx, and ovate Inmuia) of unet^nal size, but not 

 exceeding 4 lines, tlic fourth with a shorter, broader claw, and small Inriuna. 

 Stalk-like torus longer than the calyx, with a much shorter tubular process at
