13 A cultivated Old World climber. Range species of Clematis are sometimes called by this name. 



14 Since this handbook went to press, a movement has been started to adopt podgrass as the English 

 name for Triglochin, shore (or seaside) podgrass for T. maritima, and American (or short) podgrass for T. 

 striata. T. maritima, the only species with arrowlike fruit, would be called arrowpod or arrow podgrass.
