Drosera lasiantha is a Western Australian pygmy sundew whose flowering stalks deserve a close look. Its raised crown can suggest a miniature tree, but the different kinds of hairs around the flowers are more useful for identification than the silhouette alone.
Name and recognition
Kew accepts Drosera lasiantha Lowrie & Carlquist, first published in 1992. It records the species as native to south-western Australia. Kew taxonomic record
Boaz Ng documents a small rosette raised above accumulated old growth, pink flowers, and long non-glandular woolly hairs mixed with short glandular hairs on the flowering structures. His field account records lateritic scree and shallow soils around granite in southern Western Australia, including the Porongurup and Mount Lindesay areas. Field observations
The combination of hair types separates it from D. scorpioides, whose conspicuous long scape hairs carry glands, and from other raised pygmies without the same woolly covering. Comparative field account
Photograph the scape in side lighting so individual hairs can be seen. Stem height changes with age and growing history, while an image taken straight down may conceal the pedestal entirely.
Growing guidance from cultivated plants
Carlton Carnivores recommends a deep pot and a sand-rich peat mix for its D. lasiantha, with strong light and gemmae placed on the surface for propagation. This is a grower’s working method, not evidence that all plants require precisely the same mix or that every proposed propagation treatment is equally reliable. Species cultivation account
The practical goal is a root zone that remains manageable through the year. Check both the surface and the lower medium when a plant slows. A surface that looks dry does not establish that the entire pot has dried, just as a wet tray does not reveal the condition of the crown.
Use the general pygmy-sundew chapters for water quality and seasonal context, while keeping the supplied accession’s growing history. These notes apply to established plants; a newly received propagule needs attention to surface moisture while it establishes.
Gemmae and clonal continuity
The Bogman Plantenstein account documents D. lasiantha producing relatively large, pointed gemmae, around 1.5 mm long in its stock. It describes flowers on conspicuously fuzzy stalks. Cultivated accession observations
Label a propagation pot before moving material into it. Keep the parent accession and collection date with the gemmae, and preserve separate source lines rather than combining them because the species name matches. A gemma continues an existing clone; it is not equivalent to a seed produced through sexual reproduction.
What to watch over time
Record the sequence of active leaves, gemma formation and flowering. Include photographs of the crown centre when growth changes. They can help distinguish a recurring seasonal pattern from the immediate effect of transport, repotting or a sudden change in exposure.
The older stem is part of the plant’s structure. Avoid pulling attached dead leaves merely to produce a cleaner photograph. If maintenance is needed, base it on the state of the living crown and medium rather than on the assumption that all brown material indicates disease.
A well-labelled, repeatedly photographed plant becomes more useful with age: it shows both the distinctive floral covering and the way a pygmy sundew builds a raised perennial form.
