temperature than the Peruvian Ismenes, and not to grow so 

 vigorously as they do out of doors in this country. The 

 bulbs should not be watered in winter." W. H. 



Mr. Herbert has favoured me with the foregoing notice 

 of this curious little yellow and green flowered Amaryllida- 

 ceous plant. 



152. MIMOSA marginata. 



M. marginata (Eumimosa § 2. DC.) inermis, hispido-pilosa, foliis conjugato-pin- 

 natis pedunculo filiformi villoso monocephalo duplo brevioribus, petiolo 

 stipulis ovatis squab, fobolis 13-jugis ovalibus marginatis ciliatis, bracteis 

 spathulatis fimbriatis, calyce minuto in setis fisso, petalis 4 connatis, legu- 

 minibus capitatis oblongis compressis hispidissimis. 



A shrubby plant, half-hardy, prostrate, running over 

 any thing near it, and producing long slender shoots, which 

 have an elegant appearance if allowed to hang down from 

 the rafters of a greenhouse. The flowers are in small dull 

 purple heads, upon peduncles at least twice as long as the 

 leaves, and are produced abundantly in the months of July, 

 August, and September. Nothing is more easily than the 

 cultivation and multiplication of this plant ; for the branches, 

 if allowed to remain upon the ground, emit roots at every 

 joint. It is said to have survived the winter of 1836 and 7 

 in the open border ; in the nurseries it is sold under the 

 names of Mimosa mexicana, sca?idens, and 'prostrata. 



153. SATYRIUM candidum. 



S. candidum ; foliis binis subrotundo-ovatis glabris, vaginis caulis utriculatis 

 inflatis distantibus margine pellucidis laevibus, bracteis oblongo-lanceolatis 

 acutis reflexis, sepalis linearibus obtusis patentibus, petalis conformibus 

 minoribus ascendentibus apice recurvis, labello inflate- obtuso apice inflexo 

 dorso carinato, calcaribus pendulis ovario longioribus. 



One of the terrestrial Orchidacese of the Cape of Good 

 Hope, concerning which so little is as yet known in Europe. 

 It was brought home by Sir John Herschel, with whom it 

 flowered in Hanover Terrace, Regent's Park, in October ; 

 its flowers are pure white, and emit a most delightful 

 aromatic fragrance. In many respects it is like S. cucullatum, 

 which Sir John Herschel has also succeeded in flowering, 

 especially in having the sheaths of the stem inflated, and so
