 looked of recent years, possibly on account of its tendency to stand

Not commercial. 



MONEYWORT 

 Lysmachia nummularia, or Moneywort, is also known as Wandering 

 Jew, Creeping Jenny, Herb-twopence and Mouse-ear, the latter names and 

 Moneywort no doubt being derived from the rounded shape of the leaves. 

 It is very common in all the Eastern States, growing in damp places, 

 usually in lowlands near or bordering streams. Considering that it is 

 scarcely even a bog plant, it does remarkably well in the aquarium, where 

 it grows straight up to the surface of the water, regardless of where the 

 light comes from. If kept submerged the leaves gradually dwindle in 

 size, so that it is best to gather a new stock once a year. 



LACE PLANT 

 This extraordinary plant, Ouvirandra jenestralis, is a native of 

 Madagascar. Its dark-green skeleton leaves appear very fragile, but
