Dendrobium amboinense, a closer look at the lip


The most interesting feature of the flowers of Dendrobium amboinense is their lip.  The flowers in this blooming were relatively small and the plant produced only two.  But as the plant matures and grows taller, I expect it to produce up to four large flowers.

Bulbophyllum Grace Thoms traps a fly



The flower of this Bulbophyllum proved irresistible to a local fly.  The hinged lip pressed the fly into the stigmatic cavity.  The fly got stuck in place due to the stigmatic fluid.  The fly was struggling and trying to escape but without success.  Very gently I released it, the fly fled with admirable alacrity.  So far no other insect has become trapped in the flowers.  I suspect the flower is producing a fragrance with a distinct fecal tone for the flies to be so interested in the them, but so far I haven't been able to detect any fragrance at all.

Liparis saundersiana Rchb. f. a terrestrial orchid from Puerto Rico






In many years visiting the Maricao Forest I had never encountered this species.  Then in December of 2014, as I was looking at a plant of Epidendrum anceps, I noticed that there were several plants of this species a few feet away.  I could have easily missed the plants had I not looked at the right place, they are small and inconspicuous, a rosette of a few leaves flush with the leaf litter.    But once I had noticed the plants, I saw them at several places.  The plants must be deciduous since I have examined the places where they are growing many times and would have noticed them if they had been present.

For some reason all the plants I found were growing among fearsomely thorny plants and reaching them to take a photo was not that easy.  The largest group of plants was nested among a clump of Pitcairnia bromeliads.  A few plants here and there were under some thorny vines.  As I stepped in to take a photo a large thorn stabbed me on the foot through the shoe.  It was very painful.  The sacrifices one makes to get a photo!


All the plants I saw were producing seed pods and seemed in good health.  The plants are quite safe in their habitat as it is unlikely anyone will collect them and they live in a protected area.     Next year when I visit them I will wear thorn resistant clothes and footwear!
