2.2 Urtica grandidentata Miq. subsp. lombok K.Becker & Weigend , subspec. nov., Fig. 4

Type:—[ INDONESIA] Oost Java: J.H. Coert 1174 (holotype L! (L_1629139)).

Leaf lamina triangular-ovate, 100–180 × 70–130 mm; leaf margin with one order of dentation; petioles 30–50 mm long.

Note:— This very poorly understood subspecies is currently differentiated by leaf type only–but the differences are very distinctive, by the standards of Urtica systematics. Clearly more material is desirable of this taxon, which was last collected in 1909 and which is apparently restricted to montane forests.

Distribution and Habitat: — U. grandidentata subsp. lombok is restricted to Indonesia and is here reported from the islands of Java and Lombok. The subspecies is known from volcanic mountains at intermediate elevations and grows on moist soil.

Phenology:— U. grandidentata subsp. lombok flowers throughout the year.

Conservation status: —Using IUCN criteria ( IUCN 2016), Urtica Urtica grandidentata Miq. subsp. lombok K.Becker & Weigend is considered “Not Evaluated” (NE).

Representative specimens:— INDONESIA. Java: Oost-Java (Jawa Timur), J.H. Coert 1174 (L_1629139!) ;

Lombok: Rindjani volcanic mountains, north side, Putihtal, Barranco Rindjani-Caldera, 2100–2600 m, many springs, moist from the fog, 06 May 1909, J. Elbert 1121 (L_1629157!); Rindjani volcanic mountains, north side, Putihtal, Barranco Rindjani-Caldera, 2000–2400 m, many springs, moist from the fog, 06 May 1909, J. Elbert 1177 (L_ 1629156!).
