Notes on some Acanthaceous Genera and Species of Controversial Position
Acta botanica neerlandica , Volume 4 - Issue 5 p. 644- 655
The genus Stenandriopsis was created by S. Moore in Journ. of Bot. 44: 153. 1906 for a plant collected first by Vaughan Thompson and afterwards by Baron in an unspecified part of Madagascar. As the plate by which the description is accompanied depicts the specimen collected by Baron (n. 6708), the latter is to be regarded as the type. Stenandriopsis was referred by its author to the Justicieae, but this tribe is apparently accepted by him in the delimitation it received in Bentham and Hooker’s “Genera Plantarum”, and as it is in this sense a most heterogeneous mixture, this does not greatly enlighten us. Of more importance is that Moore compares it with Crossandra Salisb. and Stenandrium Nees, i.e. with genera belonging to my subfamily Acanthoideae and referred by me respectively to the Acantheae and the Aphelandreae. However, in my paper on “The Acantheae of the Malesian Area. I. General Considerations” in Proc. Kon. Ned. Akad. v. Wetensch., Ser. c. 58: 166. 1955, I pointed out that it can not belong to the Acantheae as the corolla throat lacks the incision in the adaxial side which is characteristic for that tribe. It can not belong to the Aphelandreae either as the corolla limb is subactinomorphous instead of distinctly bilabiate. As I had to rely at that time entirely on Moore’s description and on the plate by which the latter is accompanied, I was unable to arrive at a conclusion, but I suggested that the genus might represent a new tribe of my Acanthoideae. Since then I have had the opportunity to inspect in the herbarium of the British Museum of Natural History the material on which the genus was based, for which I tender my best thanks to the Keeper, and now I am able to express a more definite opinion.
