12. Trachypus longifolius Noguchi

[ Trachypodaceae ]

Among the species of Trachypus Reinwardt & Hornschuch , this species has a distinctive oblong-lanceolate leaf blade with very long, narrow and acuminate acumen ( van Zanten 1959). Its previous Philippine record is from northern Luzon (Tan and Iwatsuki 1991). The range extension of this species from northern Luzon to southern part of the Philippines, and notably its presence in Mindanao, suggests that it does not belong to the phytogeographical category of Taiwan-Philippine (Luzon) endemic group. Indeed, additional searches among the neighboring island groups south of Mindanao may show that this species actually has a broader range, representing, instead, the Wallacean biota or Central Malesian phytogeographical group ( Vallejo 2011; van Welzen et al. 2011; Vane-Wright 1990).
