Abstract

Isidrogalvia, which has been included in Tofieldia s.l. since 1805, is indigenous to South America. Cladistic analyses suggest that its closest relatives are Pleea and Harperocallis rather than Tofieldia s. str. or Triantha. Isidrogalvia differs substantively from its Northern Hemisphere relatives in having styles that are united to their apices or nearly so, tomentose leaf margins, and a seed appendage that is decurrent along the seed body. In addition, it differs from Tofieldia and Triantha in having scapes that bear many bracts, most of which are above the middle, racemes of erect flowers that are Subtended by a calyculus of free bracts, and large, multi-veined tepals that are longer than the stamens and enclose the capsules. The five species of Isidrogalvia fall into three groups, which are readily separated using capsule and bract characters: 1. falcata has 3-ribbed capsules and calycular bracts that are longer than wide; I. sessiliflora (comb. nov.) and I. robustior (comb. nov.) have incompletely 9-ribbed capsules and calycular bracts that are longer than wide; and I. schomburgkiana (comb. nov.) and I. duidae (comb. nov.) have 9-ribbed capsules and calycular bracts that are wider than long.
