A couple of endangered orchids

 Orchids are fascinating to find. There have been 19 species known from Rondeau, with all but one being native. Of course probably the best known of these is the Nodding Pogonia, which for the past several decades, has only been known in Canada from Rondeau. And of course due to its small size and extreme rarity, is probably the least often seen, as its whereabouts are kept fairly confidential. It only flowers in August, so I will feature that species a little later in the season.

One of the orchids that I like to keep close tabs on at Rondeau is the Puttyroot (Aplectrum hyemale).

 

  

I have mentioned this species in previous posts, as during the late fall and through until spring, its leaves are quite distinctive and visible. But as it puts up a flowering stem, the leaves have all but disappeared, or at least look very shriveled. I have seen this species in 6 different areas of Rondeau, although two of the spots have either not been checked in recent years, or in the case of one, seems to have disappeared altogether. I managed to find a new population earlier this year. 

In several of the places where it has been found the number of leaves have been quite few, usually less than about 6. The number of leaves in a population is the best idea to get some sense of how many plants there are, as very few will put up flowering stems, which is why I try and check on the various populations in early spring. The largest population that I have been following for several decades, have had as many as about 75 leaves on occasion, but I have seldom seen more than about 15 flowering stems appearing in that one. This year in that population, I only saw two flowering stems.

Another endangered orchid is the Large Twayblade (Liparis liliifolia). It is not, at least at this time, known to occur at Rondeau, but it might be tucked away somewhere and yet to be found! It is known from Clear Creek Forest Provincial Park in a rather out of the way location. When I first went out this late spring to see how it was progressing, this is what it looked like.

 

And this is what it looked like in peak flowering condition shown next. Another individual in leaf form only is visible right next to it. Maybe it will flower next year?? 

 Close-up views of the individual, delicate flowers are always fun to photograph!

And while I was looking for this one, another species was developing close by. It is the Fen Orchid (Liparis loesellii), not an endangered species, but not common either. It occurs in one out-of-the-way location at Rondeau, although I haven't looked for it lately. A careful look at this individual will show a very small flowering stem starting to appear, as well as the remains of last year's flowering/seed stem.
