- arrow_drop_downarrow_drop_upCollecting details
Collection 19598 was collected by E.J.H. Corner on 15th August 1929 in Peninsular Malaysia:Johor:Gunong Panti, MALAYSIA (approx. 1.8344°N, 103.9006°E, altitude approximately 500 m above sea level - Google maps). No ectomycorrhizal plants were recorded.
The surrounding habitat was described as tropical woodland with a substrate of soil, corresponding to the IUCN habitat We map from the collector's description of the habitat to the International Union for Conservation of Nature (IUCN)'s definition using a standardised set of rules. Please see this page for a full list of IUCN habitats. 1.5: Forest – Subtropical/tropical dry.
According to the GPS data the collection was in the Peninsular Malaysian rain forests WWF ecoregion The World Wildlife Fund (WWF) have divided the world into 867 terrestrial ecoregions. The ecoregion here is estimated by mapping from the GPS coordinates of the collection using data made available by Dinerstein et al (2017).
