Publication Notes on Cultivated Plants, Acta Botanica Neerlandica 4: 167 (-168), fig.1 (1955).
Type : Boom n°28046, plante cultivée aux jardins botaniques de Darmstadt (Allemagne) qui aurait été récoltée en Amérique par C.A. Purpus; conservée au Rijksherbarium, Leiden (NHN-L: holotype).
"S. brevifoliae (Torr.) Schum. & Sydov. affinis, caulibus, foliis bracteisque pulchre purpureoviolaceis, calyce glabra, corolla rosea, filamentis subglabris differt. Planta perennis, ad 40 cm alta. Caulis suberectus vel ascendens, purpureoviolaceus, lineis viridibus notatus. Folia sessilia, oblonga, acuta, basi amplexicaulia, margine longe ciliata, supra glabra vel pilis ± arachnoideis albis obsita, obscure purpureoviolacea, pruinosa , basi virentia, subtus glabra, purpurea, basalia rosulata, 14-18 cm longa, 2-2,7 cm lata, caulinia minora. Vagina 1-2,5 cm longa, ciliata. Inflorescentia pauciflora, sessilis, bracteis involucrantibus 2, acu- minatis, sessilibus, bracteolis triangularibus, membranaceis. Pedicelli ± 4 mm longi, glabri, apice longe albopilosi. Sepala 8-10 mm longa, oblonga, glabra. Petala 15-20 mm longa, pallide purpurea, basi cuneata, ± connata. Filamenta ± aequilonga, basi corollae adnata, purpurea, exteriora glabra vel pilis 1-2, interiora pilis 3-8 obsita, antheris aureis. Ovarium glabrum. Capsula ? Habitat: Mexico.
I found this fine plant in the botanical gardens at Darmstadt ( Germany) without a name. The curator of this garden, Mr. F. Boerner, informed me that Mr. CA Purpus, who travelled in the beginning of this century in Central and North America, introduced this species together with a lot of Orchids. He sent many plants to his brother, the curator of the botanical gardens at Darmstadt.
The genus Setcreasea is indigenous to Mexico and adjacent countries. S. purpurea comes near to S. brevifolia (Torr.) Schum. & Sydov, the latter being distinguished by shorter and green leaves, the white corolla and pilose stamens. From S. buckleyi Johnst. (Tradescantia speciosa Buckley non L.) our plant differs in the more robust habit, the purple colour of the vegetative parts and the nearly glabrous filaments. The colour of the leaves varies and depends with cultivated plants on the conditions in the glasshouse. Well cultivated the colour underneath the leaves comes the nearest to HCC 934/3 (Plum-purple),... The color of the top is not determinable with this chart. The color of the petals is H.C.C. 634/1 (Cobalt-violet).
The type is in the Rijksherbarium, Leiden, coll. Boom n°28046. This plant seems to be most suitable for baskets and is very easy to cultivate."
