Remarkably for T schusteri is the variation of length ratio of floral bracts to the sepals on the spike. The latter are usually somewhat shorter than the floral bracts; however they can also be equally long or even longer than. The floral bracts in a fresh condition, in culture are yellowish green to weak red, but at location are lively coloured, the Rhachis both at postfloral and as herbarium material is fully visible. The floral bracts when fresh are smooth but when dried are strongly nerved and have a hyaline, undulating edge.
According to statements from P. Koide growing in the near vicinity to T. schusteri you also find the yellow flowering T. bourgaei Baker and the violet flowering T. rodrigueziana Mez. Nevertheless it is not considered that T schusteri is a hybrid between both. —SeeRauh 1988ep. 38(5): 214-215
