Most nearly allied to G. metimfolhim, from which it differs in having larger leaves, the outer bracts 

 somewhat larger and all obtuse, the whorls many-flowered and the upper lip of corolla entire, not 

 emarginat;?. The habit also is usually different in G. ovatum; the stems are ascending and only rooting 

 near the base, in G. melissifoiium prostrate or scandent and longer, often rooting below for half their length. 

 The varieties differ a good deal in appearanc?, but there are no good diagnostic marks except absence 



of pubescence in var. flaccida, which bears to the type precisaly the relationship borne to G. strobilinum 

 its var. arid is.
