Hoya lacunosa — Poonsak (IML 1648)
Explain the historical Poonsak/IML1648 relationship without authenticating all similarly labeled plants.
Explain the historical Poonsak/IML1648 relationship without authenticating all similarly labeled plants.
Overview
A 2007 Stemma account links Poonsak with IML1648 and a Thai collection. Its reported narrow foliage and ascending shoots distinguish the material described by that author, but do not establish a diagnosis for unidentified plants.

What We Know
- Collection and name: Randal associates this collection with southern Thailand and describes Poonsak as David Liddle’s guide. The accession number and reported history are retained together, pending original collection and distribution records.
- Leaves and growth: The account describes narrow, bright-green leaves with visible veins and upward shoots that bow as leaves develop. These observations describe the source’s material; they are not measured care requirements.
- Using the label: Keep the received name and any acquisition records. An accession number can point toward documentary history, but a copied label cannot establish continuity by itself.
What We Are Still Learning

What would help: Original naming or acquisition records, identified material, dated observations and documented conditions appropriate to this question.
What is the precise collection locality?

Common Misconceptions
- Narrow leaves alone cannot authenticate IML1648.
- The collection account does not establish the wild origin of every plant carrying Poonsak.
