Austrian Gold of Pleasure. Fl. May, Ju. Clt. 1795. PI. 1 ft. 



Cult. Notwithstanding the ridiculously pompous English 

 name of Gold of Pleasure which these plants bear, and which 

 seems a satire on the articles of which it is composed, as yield- 

 ing nothing but disappointment, they are not worth cultivating 

 except in general collections. Both perennial and annual species 

 can only be increased by seeds. They require no care. 



LXIV. EUDEMA (in honour of Eudemus of Rhodes, a 

 pupil of Aristotle). Humb. et Bonpl. pi. -ffilquin. 2. p. 133. 

 t. 123 and 124. D. C. syst. 2. p. 518. prod. 1. p. 202. 



LIN. SYST. Tetradynamia, Siliculosa. Silicic ovate, with 

 many-seeded cells and concave valves, with the dissepiment per- 

 forated at the top. Style filiform. Seeds oval. Cotyledons 

 (from the figure) incumbent. Small tufted perennial herbs, with 

 crowded, ciliated, blunt small leaves, and axillary, stalked, solitary 

 white flowers. 



1 E. RUPE'STRIS (H. et B. pi. sequin. 2. p. 133. t. 123.) leaves 

 linear ; calyx shorter than the corolla ; cells of pods 8 or 10- 

 seeded. If. . G. Native of South America in mountains near 

 Quito on high and cold rocks. Draba Humboldtii, Desv. jour, 

 bot. 3. p. 171. Root woody, fusiform, branched. Flowers 

 white. Leaves smooth, not ciliated. 



Rock Eudema. PI. 2 or 3 inches. 



2 E. NUBI'GENA (H. et B. pi. sequin. 2. p. 136. t. 124.) 

 leaves spatulate ; calyx longer than the corolla ; cells of pods 4- 

 seeded. If.. G. Native of the Andes about Quito on high rocks. 

 Root elongated, fusiform, almost simple, much longer than the 

 herb. Flowers white. Leaves ciliated. 



Cloud Eudema. PI. 1 inch. 



Cult. As there has not yet been a species of Eudema intro- 

 duced into Britain, it is difficult to say what method of cultiva- 

 tion would suit them best, but we would recommend their being 

 kept in pots which should be well drained with potsherds, and 

 planted in a mixture of sand, loam and peat, and placed in a 

 green-house or frame, so that they may be protected from the 

 frost. It is evident from the nature of the plants that they must 

 be either increased by seeds or cuttings ; but they are not worth 

 cultivating except in botanic gardens. 



LXV. NE'SLIA (meaning not explained.) Desv. journ. 3. 

 p. 162 and 163. D. C. syst. 2. p. 519. prod. 1. p. 202. 



LIN. SYST. Tetradynamia, Siliculosa. Silicle almost glo- 

 bose, indehiscent, with concave valves, 1 -seeded and 1 -celled 

 from the want of a dissepiment. Seeds somewhat globose, pen- 

 dulous. Cotyledons ovate, thick, incumbent. An annual erect 

 herb, with somewhat the habit of Camellna saliva. Stems round, 

 sparingly branched, whitish, pubescent, or a little hispid at the 

 base. Cauline leaves alternate, sagittate, stem-clasping, oblong- 

 lanceolate, entire. Racemes terminal, elongated. Pedicels fili- 

 form, bractless. Flowers small, yellow. 



1 N. PANICULA'TA (Desv. 1. c.) 0. H. Native of corn-fields 

 and sandy places almost throughout the whole of Europe, from 

 Turkey to Sweden, and from Spain to Petersburgh, also in 

 Iberia about Tiflis ; in the south of Tauria and in Siberia be- 

 tween Zmeof and the Irtish. Myagrum paniculatum, Lin. spec.

Panicled Neslia. Fl. July, Aug. Clt. 1683. PI. 1| foot. 



Cult. This plant is not worth cultivating except in botanic 

 gardens. It only requires to be sown in the open border, and 

 treated like other hardy annuals. 



LXVI. EUTRE'MA (from tu, eu, well ; rprifia, trema, an 

 orifice ; dissepiment incomplete.) R. Br. in app. Parry's voy. 

 append, p. 9. t. A. 



LIN. SYST. Tetradynamia, Siliculosa. Silicle short, 2-edged, 

 with keeled valves, an incomplete dissepiment, and many-seeded 

 cells. Plant with the habit of Braya. Root thick, fusiform, 

 from which spring numerous simple few-leaved stems. Radical 

 leaves stalked, ovate-lanceolate, quite entire or a little toothed, 

 thickish, the uppermost cauline ones sessile. Corymbs dense, 

 7-8-flowered. Flowers white ; anthers yellow. Dissepiment 

 complete at the base and apex, but not so in the middle. Perhaps 

 the genus Braya ought to have been inserted here. 



1 E. EDWA'RDSII (R. Br. 1. c.) %. H. Native of Melville 

 Island in the neighbourhood of Winter Harbour. Plant smooth. 



Edrvards's Eutrema. Fl. April, May. PI. 2 to 3 inches. 



Cult. This plant should be grown in small pots filled with a 

 mixture of peat, loam and sand, well drained with potsherds at 

 the bottom. It should be treated as other alpine plants. It 

 can only be propagated by seeds. 



LXVII. ORE' AS (from optiac, oreias, nymph of the moun- 

 tains, in allusion to the habitat of the plant.) Cham, et Schlecht. 

 Linnaea 1. p. 29. 



LIN. SYST. Tetradynamia, Siliculosa. Silicle lanceolate, com- 

 pressed, 1 -celled, from the dissepiment having vanished; valves 

 flattish, with a nerve running through the middle. Seeds nu- 

 merous, egg-shaped, hanging from the upper part of the placen- 

 tarious nerve by long umbical funicles. A small alpine perennial 

 herb, with the habit of Carddmine bellidifolia. Leaves radical, 

 stalked, smooth. Bracteas crowded under the pedicels, appear- 

 ing like an involucre. Flowers in short racemes, white, some- 

 times veined with dark-purple. Calyx loose, equal at the base. 

 Petals entire, unquiculate, equal. Filaments equal, toothless. 

 Style very short, crowned by a capitate stigma. This genus is 

 sufficiently distinct, in the dissepiment being absent, as well as 

 the glands. 



1 O. INVOLUCRA'TA (Cham. 1. c. t. 1.) 2/.H. Native of the 

 island of Unalaschka on the tops of the mountains among stones.
