Stone Jaguar Posted August 17, 2016 Report Share Posted August 17, 2016 Greetings after a prolonged absence. After having flowered and hand-pollinated a sexual pair of Squamellaria kajewskii for the past nine months, I was very pleased to note that one of my 15 month-old S. guppyana opened its first flower yesterday. I have included an image for reference. I was struck by how small the corolla is compared to its putative sibling species. The anthers are in contact, almost looking fused and reminiscent of some asclepiad flowers. Both of these Solomon island hydnophytines are remarkable for the speed with which they grow in cultivation in my collection. Of the two, S. guppyana is by far the faster; indeed, by a wide margin it is the fastest growing hydnophytine I have experience with. The confusion that surrounds some of the characteristics differentiating these two species, originating with a mixed collection for one of the types, appears to have again crept into the key included in Chomicki and Renner's recent revision of the genus. The floral characters (corolla length x width) they cite are mixed. As is evident here, it is S. kajewskii that has a long, slender corolla tube, not S. guppyana The leaves and caudexes are as described in the paper. As an aside, S. guppyana appears to be somewhat intolerant of very bright light when greenhoused. Unlike S. kajewskii and most other hydnophytines in cultivation, I would recommend some shade over the plants to avoid premature leaf drop.
