I. longifolia ; caule prostrate angulato glabro, foliis breviter petiolatis oblongo- 

 lanceolatis obtusis mucronulatis crassiusculis glabris, pedicellis unifloris 

 folio subaequilongis supra medium articulatis minute bibracteolatis, se- 

 palis ellipticis obtusis glabris. Bentfiam plant. Hartweg. p. 16. no. 97. 



A truly beautiful pjant, introduced by the Horticultural 

 Society from Mexico, where Mr. Hartweg found it in the 

 pastures about Leon, called Quehra platos. It has been ex- 

 tremely well characterized by Mr. Bentham in his very useful 

 Pla7it(B Hartwegiance. 



The large and semi transparent flowers diffuse a delicious 

 perfume, resembling noyeau. 



It is a half-hardy perennial, with a long spindle-shaped 

 root and a stem from four to five feet long, without any side 

 branches ; unless supported by some other plants or tied up 

 to a stick it would probably become nearly prostrate. 



The time of flowering is from July to September ; each 

 flower opening in the morning and lasting all day, if not ex- 

 posed to the mid-day sun, and each stem producing a fresh 

 flower nearly every day. Being very fragrant it is well worth 

 placing in the sitting-room during the blooming season, 

 especially as the plant, when in flower, seems to require 

 shade. 



It appears diflficult to increase except by seeds, which 

 probably will be produced freely when the plants become 

 older ; but it may be multiplied by the young shoots, which 

 spring from the crown of the root, when about two or three 

 inches long ; and as each root produces three or four shoots
