- This page is about the Cassia tora described by Linnaeus. Later authors usually applied the taxon to Senna obtusifolia.
Senna tora (originally described by Linné as Cassia tora) is a legume in the subfamily Caesalpinioideae. It grows wild in most of the tropics and is considered a weed in many places; its native range is not well known but probably South Asia. It is often confused with Chinese Senna or Sicklepod, S. obtusifolia. If it is given a distinct common name at all, it is called Sickle Wild Sensitive-plant.
history of this plant is extremely confused, even by the standards of Senna
. S. tora
and S. obtusifolia
were for long and are often still held to be - and may eventually be verified as - a single species. Hence, taxa
referring to either species
were indiscriminately applied to both.
- Cassia boreensis Miq.
- Cassia borneensis Miq.
- Cassia gallinaria Collad.
- Cassia numilis Collad.
- Apparently a misprint for Cassia humilis, which would have been applied to this species in error as it is properly a synonym of Senna obtusifolia and Chamaecrista kunthiana, depending on the author.
- As discussed above, the Cassia tora of other authors refers to Senna obtusifolia
- Cassia tora L. var. borneensis (Miq.) Miq.
- Cassia tora L. var. b, var. humilis, and var. obtusifolia all refer to Senna obtusifolia
