Strobilanthes tonkinensis is a species of plant.
Names[edit]
Many sources still refer to the plant by the synonym Semnostachya menglaensis, but this name is not a validly published name as the herbarium where the type specimen is located was not specified.[7]
In Chinese it is called 糯米香 (nuò mǐ xiāng "glutinous rice fragrance").[7]
Taxonomy[edit]
S. tonkinensis appears related to S. maculatus, but has much larger flowers, leaves, and bracts; as well as having denser trichomes.[1]
Description[edit]
The plant is herbaceous with a woody base and shrubby, roughly four-sided, pubescent branches.[1][7] When dry the plant is fragrant.[7]
The leaves are ~23×12 cm or a little smaller and egg-shaped, starting wide and narrowing quickly to the acuminate apex (tip). The margins are nearly entire, with irregular sinuous 'teeth'. The leaf petioles are 3–4 cm long.[1] Adaxially there are prominent striated cystoliths.[1][7]
S. tonkinensis has white flowers that are opposite, arising from pedunculate, tomentose spikelets in the upper axils.[1] The bracts are 10×3 mm, slightly spathulate, obtuse, and densely tomentose.[1] Bracteoles are 6×1 mm in size, lanceolate, obtuse, and densely tomentose.[1] The calyx is also obtuse and tomentose, and about 8.5×1.4 mm.[1] The corolla lobes are short and 6x6 mm with a subacute and sinuate apex.[1] The stamen filaments are hairy and laterally bifurcated at the base with a pubescent line running down.[1] Anthers are 3.5 mm long.[1] The pollen grains are 85×60 μm.[1] The stylus 20 mm long and glabrous with a 3 mm stigma.[1]
The capsule is 15 mm long and 4 mm wide, with a compressed base and acute apex.[1] It's minutely glandular-pubescentand contains 4 glabrous seeds.[1]
Distribution[edit]
The plant can typically be found in tropical and subtropical moist broadleaf forests at 200–1500 m in elevation in Vietnam, Thailand, China (Yunnan and Guangxi),[7] and Myanmar (Chin State and Tanintharyi Region).[8]
The type was found by Benjamin Balansa in Tonkin (Northern Vietnam) in the forests of the Ba Vì mountain range at 400 m in elevation.[1]
Ecology[edit]
S. tonkinensis flowers from April–June and in December, and fruits in June and July.[7]
