A sundew need not be covered in a wide ring of leaves to show its most useful identifying feature. In Drosera androsacea, the closely packed stipules form a conspicuous pointed structure at the centre. Watching that crown through the season reveals a different picture from the permanently lush miniature rosette often imagined when someone says “pygmy sundew”.
Name and field appearance
Drosera androsacea Diels is a Western Australian species published in 1904. World Flora Online records its Western Australian distribution and nomenclatural reference. World Flora Online species record.
A firsthand field account describes small rosettes around 1.5 cm across, flat-spreading leaves and a tightly stacked, pointed stipule bud. During flowering, some plants retain only a few recent leaves, giving a roughly five-sided arrangement. White to pale pink flowers may carry pink streaks, especially visible beneath the petals. The account associates the species with exposed, poor substrates in inland mallee habitats. Fierce Flora field profile.
A Melbourne University herbarium specimen independently records the species from gravelly heath in Western Australia. A specimen label documents a particular collection rather than the entire ecological range, but it is useful supporting evidence that the species should not be characterised as a tropical rainforest plant.

Understanding the crown
Stipules are structures associated with the leaf bases. In pygmy sundews they can become a prominent part of the central crown. They are not an underground tuber, and a compact stipule bud should not lead to the storage methods used for tuberous sundews.
Photograph the crown from the side as well as from above. A top-down picture may show a small pale centre without revealing its pointed profile. Keep a date with each image: a flower-season plant carrying few leaves should not be compared uncritically with a fully leafy individual photographed at another stage.
This is also why leaf number alone is a poor health test. The field account documents a sparse seasonal appearance. The relevant question is whether the plant is following a coherent cycle and retaining a sound centre, or whether it has suffered an abrupt, unexplained decline.
Cultivation at pygmy scale
The general pygmy-sundew approach supplies a starting framework: bright growing conditions, a nutrient-poor medium, suitable water and minimal root disturbance. It does not establish a universal summer watering recipe. The ICPS describes the importance of the seasonal cycle and warns that the delicate, often long roots make transplanting risky. ICPS pygmy sundew guide.
For D. androsacea, avoid deriving a potting mixture directly from the words “compacted” or “clayey” in a field description. Soil at a natural site interacts with a much larger moisture profile than a small container. A copied surface texture may behave very differently indoors or on a nursery bench.
Keep an established accession's successful routine intact while documenting any adjustments. Record whether the crown becomes more compact, how many fresh leaves remain and when growth resumes. This profile does not give a tested species-specific minimum temperature, tray depth or dry-rest duration, because the consulted sources do not establish those limits.
Propagation and the integrity of a collection
The pygmy group is famous for gemmae, which are vegetative propagules rather than seeds. Where a verified accession produces them, label the batch immediately and place them deliberately in their destination pots. A tiny displaced propagule can later create a confident-looking but incorrect species label if it lands among other pygmies.
Allow sufficient space to observe each developing plant. Repeatedly moving rooted juveniles to improve a display can be more damaging than accepting an initially sparse arrangement. Multiplying one accession also preserves one lineage; the number of pots does not measure genetic diversity.
Flower colour can help document the accession, but it should not become a cultivar claim without the required evidence and name history. Pale pink and white flowers reported within a species are not automatically separate botanical varieties.
Reading the landscape and the record
A seasonal plant can be easy to overlook outside its conspicuous phase. Absence from one visit or photograph is not a population census. For the same reason, a cultivation account should follow the plant across a full cycle before presenting an apparent disappearance as either death or a successful dormant rest.
The encyclopedia places D. androsacea with pygmy sundew diversity, alongside species whose central buds, floral structures and growth habits provide better distinctions than overall size. Its pointed crown is an invitation to look more closely at the part of a sundew that remains when the display of leaves changes.
