1. Polygala longeracemosa H. Perrier  

in Bull. Trimestriel Acad. Malgache ser. 2, 14: 9. 1932.

Lectotypus (designated here [second step]): MADAGASCAR. Prov. Toliara: Bassin supérieur du Mandrare (SE): Mont Amboahangy prÈs d’Esira , [24°15’S 46°39’E], 1000- 1150 m, 25.XI.1928, fl., Humbert 6830 ( P [ P00375348]!; GoogleMaps   isolecto-: P [ P00375346, P00375347]!) (Lectotype [first step] designated by PAIVA, 1998: 258). GoogleMaps   Paralectotypus: MADAGASCAR.Prov. Toliara: Massif de Beampingaratra (SE): Mont Papanga , versant NW, c. 1200 m, 3-4.XI.1928, fl. &fr., Humbert 6405 ( P [ P00375343]!;   isoparalecto-: P [P00375344, P00375345]!).  

Observations. – PAIVA (1998) cited Humbert 6830 (P) as the holotype of the name P. longeracemosa   and effected lectotypification in accordance with the ICBN (MCNEILL & al., 2012, Arts. 9.2, 9.11). However, the gathering of Humbert 6830 at P consists of three specimens. Consequently, we designate the sheet [P00375348] as the [second-step] lectotype as allowed under Art. 9.17 because it is the most complete specimen and the label was annotated with the word “type” in Perrier’s hand.

Distribution and habitat. – Polygala longeracemosa   is distributed in the mountains of southeastern Madagascar, including the massifs of Andohahela, Kalambatritra and Ivakoany and on the Horombe Plateau at elevations from 900- 1750 m. The species occurs in secondary or degraded grasslands, ericoid shrublands, and forests edges, usually in rocky areas ( Fig. 1 View Fig ).

Conservation status. – Polygala longeracemosa   is known from 13 locations and subpopulations, four of which are situated in Protected Areas (Andohahela National Park and Kalambatritra Special Reserve), but with a somewhat restricted Area of Occupancy (minimum of 140 km 2) and Extent of Occurrence (c. 14,000 km 2), it is assigned apreliminary conservation status of “Near Threatened” (NT).
