A Paramo Parasite

The harsh conditions of the high altitude regions has forced many plants to take major adaptive measures. This plant from the genus Aetanthus solves its problems by parasitizing trees in much the same way as mistletoes do. Its hard to find information on many of these plants but, supposedly, the plants germinate on open wounds of trees where they are able to tap into the sap flow. These are found in the Polylepis forests at around 10-13000ft in the Andes. The long orange flowers are a sure indication of pollination by hummingbirds and the Shining Sunbeam is a likely suspect in the areas where these grow. The Shining Sunbeam is a beautiful hummingbird which is mostly orangish-brown with a patch on its rump that can shine almost any color but often looks like its plated with gold.

Passion Flowers

The large vines from the genus Pasiflora dont just have some of the most beautiful, and extravagant flowers I have ever seen but, also produce some of the most delicious fruit! I have never seen the fruit for sale in the United States, despite the fact that "Passion fruit" is such a common flavor. The granadilla (P. lingulares) is the most common in Ecuador and the probably is the best for eating alone, because it is sweet and juicy. The taxo and the maracuya (P. mixta, P. edulis) are more acidic and have a very strong flavor which is great for juice. One of these is the "passion fruit" that North Americans are familiar with. I once had one growing on a wall in my bedroom opposite a west window, and it quickly spread over the whole area. Unfortunatly, there was just not enough light there for it to bloom but it was nice having a

green wall. They are widely cultivated, mostly for their flowers. Here in Albuquerque hardy varieties are sold but they are not practical, because the require lots of water.

Paramo Lithophytes

When you get "down" to about 12-

11000ft, orchids become more varied and common. Venturing off the trail to explore rock faces such as the one

in the photo below, reveal a hand-full of lithophitic species. A few species of Stelis, Pachyphyllum, and

a few other pleurothallids grow from mossy cracks in rocks. The little vandacious Pachyphyllum always seem to be in every stage of budding, seeding

and blooming at the same time. These orchids are easy to find if you look in

the right places but if you really want to see their flowers, a magnifying lens is

nescesary. I carry a "loupe" which is a very small but very powerful magnifying glass, and its small enough that I can wear it around my neck. The clump of Pachyphyllum must be dozens of years old yet it is only about6 inches tall and each growth is about 1/2 inch wide! The Stelis too can be very miniscule. I found a species with leaves only half an inch tall and flowers so small that even the loop didnt show much. They are known for being extremely difficult to identify so I didnt even try.

Myrosmodes

Add this to the number of times orchids have blown my mind! I usually keep my eyes peeled for them on any hike but I was surely not expecting to find them at 15000ft on the side of a mountain I was climbing! These Myrosmodes are the most extreme example of this adaptable family I have ever encountered. Growing where the intense sun quickly burns exposed skin, yet the bitingly cold wind robs all warmth from a resting hiker, these plants like most others that are able to grow here lie low and even recess themselves into the ground if they are able. Effectively out of the wind, the leaves are able to become quite warm in the day, however, camping nearby revealed that the temperatures sink below freezing at night. This means that these plants grow with a 30-40 degree F difference between day and night.

I googled the genus name and found a botanical drawing that showed the the vast majority of the plant is underground. The rosette seen in the photos is the tips of the leaves which sink another few inches into the soil. Their proportionally massive spikes(although it is only a couple of inches tall) illustrate the true size of the orchid. The one to the left shows a spent spike which has forced its way up through the layer of cushin plants as well as the tiny recessed leaf-crown. There were perhaps two species because I also found plants with much longer, thinner spikes, but it could be environmental conditions that cause that change.
