PELTANDRA (Greek, referring to the peltate an- 

 thers). Aroide<t. Arkow Arum. An east American 

 genus with two species which have been much con- 

 fused. They are stemless herbs, the glossy arrow- 

 shaped leaves arising from strong underground parts: 

 fis. mondcious and naked, the staminate ones on the 

 up])iT part ..f thi- Icing spadix, the anthers sessile and

 noilia: spaihi- ii-ually exceeding the spadix: fr. a 1-3- 

 sceded, mostly leathery berry, borne in large globose 

 clusters. Peltandras are excellent subaquatic plants, 

 their large thick sagittate leaves always adding variety 

 and interest to margins of ponds and to bog gardens. 

 Single specimens or chimps are usually most prized. 

 l'.-ltaridi-;is are ea>y to colonize. .
