Persicaria microcephala (Wall. ex D.Don) Sasaki ??

Thank you.

Saroj Kasaju

[J.M. Garg]

Yes, appears close as per images at 
https://efloraofindia.com/efi/persicaria-microcephala/

There is a closely related species as 
https://efloraofindia.com/efi/persicaria-greuteriana/

Google AI give the following differences between the two:

Persicaria greuteriana and Persicaria microcephala are closely related, often confused perennial knotweeds (Polygonaceae family) originating from the Himalayas and Asia, with P. greuteriana previously considered a variation of P. microcephala. P. microcephala (e.g., 'Red Dragon') is known for variegated foliage and white flower heads, while P. greuteriana is a distinct species in some classifications. 

Persicaria microcephala (Tiny-Head Knotweed) 

• Characteristics: Perennial herb, 40-60 cm tall, with stout rhizomes and erect/decumbent, branched stems.
• Flowers: Tiny white flowers in 5-7 mm diameter heads.
• Leaves: Often feature variegated, colorful patterns (especially in 'Red Dragon'), often with a v-shaped mark.
• Habitat: Moist, boggy soil or beside water. 

Persicaria greuteriana

• Taxonomy: Accepted as a distinct species in some databases (e.g., POWO), native to the Himalaya to China (Yunnan) and N. Thailand.
• Notes: Previously closely associated or confused with P. microcephala (often referred to as Persicaria wallichii Meisn.).
• Habitat: Temperate biome. 

Differences

• Taxonomic Status: P. greuteriana is listed as an accepted, separate species, whereas P. microcephala is a well-known, widely cultivated, and often variegated species.
• Morphology: Galasso noted P. greuteriana as a possible variation of P. microcephala, suggesting high similarity, though they may have different hairiness on the stems or bracts (ocreae).
• Usage: P. microcephala 'Red Dragon' is popular in horticulture for its foliage
