Hoya lacunosa — Perangin Durian
Compare the received Perangin Durian name with historical Perangin Durian and Langkawi Island labels carrying IML 1896.
Compare two differently worded IML 1896 label occurrences without assuming a connection to the material recorded under the received Perangin Durian name.
Overview
Perangin Durian is retained here as a received name in cultivation. The historical checklist pairs that name with IML-1896, while MyHoyas captions IML 1896 as Langkawi Island. These records raise a question about label history. Neither record links the received-label material to that accession or establishes that the records refer to the same plant.

What We Know
- The historical checklist records “Hoya lacunosa cv. 'Perangin Durian' IML-1896”. This preserves the checklist wording, including cv.; it does not authenticate a cultivar, a wild locality or current ownership.
- MyHoyas uses the caption “Hoya lacunosa 'Langkawi Island' IML 1896”. Its visible album update is 11 July 2019, which does not date the accession’s origin or introduction.
- The shared number occurs with Perangin Durian in one record and Langkawi Island in the other. The records do not explain that difference or connect either occurrence to the material recorded under Perangin Durian here. That connection remains unresolved.
- Measured descriptions of leaves, flowers and growth are not documented for the received-label material here.
What We Are Still Learning
Why do the Perangin Durian and Langkawi Island records share IML 1896?
What would help: The original IML 1896 accession card or catalogue, dated label changes, locality records and any associated voucher. Establish whether the words describe a location, a received name or a later label error.
Can material received as Perangin Durian be traced to IML 1896?
What would help: Original labels and dated acquisition and propagation records connecting this specific plant to that accession. A matching name or leaf appearance cannot supply that chain.
Which traits persist through growth and propagation?
What would help: Dated observations and measurements following the same identified material and its cuttings, with recorded growing conditions.
What are its flowers and flowering behaviour?
What would help: Dated observations and identified flower photographs, with measurements and explicit notes about scent, bloom duration and conditions.
Are distinctive growing requirements supported?
What would help: Scientific observations or controlled cultivation comparisons of identified material, with reported methods and conditions.
Common Misconceptions
- A received cultivation name or similar leaf pattern does not authenticate a cultivar or clone.
- A descriptive name does not establish leaf colour, trait stability or a particular light requirement.
- An accession number shared by two label records does not by itself establish that their living plants are identical.
- A place word in a checklist or collection caption does not establish a wild collection locality.
