 The iliscovery of A', articiilnliiiii in its type locality hasenalileil us to drai' u]i t he 

 confusion that has arisen in reference" to this species, which has liecome a pcrplexiuf: 

 ii.trtrrc^atc. Leiherx^'s specimens seem to he exact ihi|)licates of those of < Jeyei-. It is 

 evident that the numerous later c<illections that have hei'U named /■,'. nrlirii/nliiiii 

 ha\f lu'en wrouii'ly rel'i'i-red, and umst he looked foi' elst'where. In <'onnection with 

 the oriLrinal desci'iption Hooker piihlishes a lield note of < ieyer, which desciilies the 

 hahit of the plant so well that \\t' ([iiote it as I'ollows: 



"In April the yonnir plants are wholly suhmcr^ed, and presi'iit the ap|iearanie of 

 some articulated .hnii-iis, the Icaxi's, or rather the petioles, heuifx similarly terete and 

 jointed. < U\ emer<:injr above the water tlu'.sc pctioU's expand into laiidn.i' at t he top, 

 retaining the jointed swollen character in the costa. The radical petioles are s to In 

 inches lonjr. Those of the stem, in proportion as they are out of the water, become 

 flattened and the maririn spinuloso-ciliate.""
