NOTE In Binomials 1 1990 and confirmed in DeRebus I 1994 T. purpurea and T straminea were split with no reason given. Therefore the description has been taken from Mez 1934. In Mez’s key the difference was shown as ‘Floral bracts less or equalling the sepals for T. straminea and floral bracts a little exceeding the sepals for T. purpurea’. BUT in his descriptions he has T. straminea bracts 18mm sepals 16mm, sessile? and T. purpurea bracts 12mm sepals 11mm with pedicel up to 5mm!!! Whereas Baker in 1889 says T. straminea has calyx reaching the tip of the bract and T. purpurea has calyx as long as the bract.
In California Brom trade 1998
purpurea = short stiff leaves (Mez rigid, 20cm x 14mm wide)
straminea = long lax leaves (Mez leathery, 25cm x 10mm wide)

Peter Tristram 02/18 ... "In nature there are Pacific coastal plants with succulent, relatively short leaves generally regarded as purpurea and mountain plants, usually epiphytic, with long, lax, softer leaves that are thought to be straminea.
Then there is cacticola, which I have seen growing with straminea in the Cochabamba area of northern Peru. You also find what could be purpurea in the high Andes and many in-betweeners.
Interestingly none of the plants with distinct branches with more imbricate fb (usually lax after anthesis) that we tend to call cacticola, are fragrant, whereas all of the purpurea and straminea forms I have come across, are. Food for thought. Great bunch of plants!!
Franz Gruber has an amazing collection of these species, from Peru and Ecuador – damned shame about the bloody Xylella restrictions!"
