I agree with Lanjouw that Sandwithia is much more closely related to Sagotia than to the Crozophoreae and that the valvate or imbricate aestivation of the calyx-lobes has little systematic value.
The distinction from Sagotia however is quite clear because of the nonaccrescent female calyx in Sandwithia. The calyx is not deeply incised and is more like the calyx of the Hippomaneae. The tribal segregation of Cluytieac, Gelonieae and Hippomaneae still requires the thorough revision to which Bentham already called attention.
