Syntypes.

Chile, Quillota, parasitic on Adesmia , [in Chile 1828-1831] C. L. G. Bertero s.n. (P, not seen); Chile [from the collection number this was in "various localities in the Andes", during the period from 27 Oct.-26 Nov. 1841], T. Bridges 1273 (BM, not seen, K, not seen).

Note: Tepals purple to brown with clearer margins (Fig. 6A), 9-18 in number, stamens in 4 whorls (spirals), with> 70 pollen sacs. Growing in older stems of Adesmia shrubs in Chile, Argentina, Peru, and Bolivia ( Figs 2 , 3 ). Our morphological (Suppl. material 2) and molecular data ( Fig. 1 ) show that the species is nested among other species of Pilostyles , indicating that Gardner’s transfer was erroneous.

Figures

Figure 1. Phylogenetic relationships in Apodanthaceae obtained under maximum likelihood from the mitochondrial gene matR (A) and the nuclear ribosomal RNA gene 18 S (B). Shown in red are the specimens we wanted to identify to species. Numbers indicate bootstrap support> 70 %.

Figure 2. Geographic distribution of Apodanthaceae based on label information from 785 herbarium collections.

Figure 3. Phylogenetic relationships among the hosts of Apodanthaceae (legume relationships from Wojciechowski et al. 2006) and among the species of Apodanthaceae (from Bellot and Renner in review). Identical colors link parasite species and their host (s) and are also used in Figure 2. Dashed lines represent associations with rarely reported hosts; hosts in bold are the most common ones.
