Notes.

In describing Amsinckia patagonica , Spegazzini (1902) cited a syntype from Patagonia, Argentina. The gathering consists of a collection he made in Río Santa Cruz, Argentina, in 1882. No specimen corresponding to the material cited in the protologue was located at LP, where Spegazzini worked ( Stafleu and Cowan 1986). However, a duplicate of the syntype in agreement with the protologue is kept at GH. This material matches the diagnosis coined by Spegazzini, and, thus, it is here chosen as the lectotype of the name. Rudolph A. Philippi (1895) based the description of Eritrichium parvulum on three collections made by F. Philippi on a trip to the Atacama Region, Chile, in 1885. The first gathering consists of a collection from Caldera, while the other two were made in Piedra Colgada and Chañarcillo. Four duplicates of the syntype collected in Caldera are kept at CORD, GH, and SGO. Among the other syntypes, a duplicate of each collection is housed at SGO. All specimens are in agreement with the localities and the diagnosis cited in the protologue. The syntype from Caldera is preferred as it shows the best quality of preservation of the important diagnostic features of the taxon. Thus, a duplicate from this collection is here chosen as lectotype of the name.
