15. ** § Mimosa craspedisetosa Fortunato & Palese

Described in 1999 based on incomplete material (fruiting only, the flowers at that time unknown). J.R.I. Wood et al. 22858 (LPB, K, USZ) is apparently the first flowering collection and confirms placement in ser. Leiocarpae of sect. Batocaulon as proposed by Fortunato & Palese (1999).This placement is further supported by its robustly supported inclusion in Clade N of the molecular phylogeny of Simon et al. (2011), which includes ser. Leiocarpae pro parte. This species is now recorded from four localities in eastern Bolivia: Cerro San Miguel, the type locality; Quimome, old rd to El Tinto (J.R.I. Wood et al. 22858, LPB, K, USZ); 60km E of Roboré (J.R.I. Wood et al. 24488; J.R.I. Wood & Pozo 26084; J.R.I. Wood 27127, LPB, K, USZ) and Taperas (J.R.I. Wood et al. 27874, LPB, K, USZ). This suggests that this species is perhaps restricted to Cerrado Chaqueño (Abayoy) habitats rather than being restricted to Chaco woodland as originally described. Although M. craspedisetosa is still, as far as known, endemic to eastern Bolivia, it appears to be spreading along the line of the road from Santa Cruz to Brazil ( Wood 2011), the population at Taperas being found for the first time in 2013 in an area visited frequently in earlier years.
