Philpatrick Posted February 20, 2019 Report Share Posted February 20, 2019 Myrmecodia cf. pulvinata notes and images. Here are some observations on a Myrmecodia cf. pulvinata; to see how it compares to Myrmecodia tuberosa "pulvinata" and possibly find out more about the origin, identity and characteristics. The plant has been growing in a terrarium under grow lights. It is growing fast and large. When the flowers emerge, to me, it looks like molars surfacing through gums. The characteristics I find most interesting are the translucent petioles that are sharply keeled and the clubbed spines. Myrmecodia tuberosa "pulvinata" is noted to be a heterostylous species. Some plants of the population will produce brevistyle flowers and some plants will produce longistyle flowers. After examining the flower, it appears that this particular plant is producing longistylous flowers with a long style reaching to the apex of the corolla. The anthers were expired and it was difficult to determine a location. The anthers did not have any pollen when I checked the flowers, so I have not noticed if this plant has the characteristic pollen with a single vesicle (fluid filled sac). The bottom of the corolla had a ring of hair like a whisker biscuit, like those used in archery for holding the arrow. I noticed something strange about the flower; there was a "shield" of flower tissue capping the corolla with the stigma pressed against it. More detailed images can be taken when it's next flower matures. Another thing I noticed, is that ants have been putting debris around and on top of the flowers. Also, the flowers have roots surrounding them on the alveoli rim. I think the high humidity in the terrarium could be causing the aerial roots to develop. The caudex has several aerial roots as well, the stem does not have any roots. I am not sure how Anthorrhiza derived that name but doesn't Anthorrhiza translate to flower-root? Is this a trait of Anthorrhiza also? Has anyone noticed roots growing around the alveoli and flowers of other species? Quote Link to comment Share on other sites More sharing options...
