Is it Spring (Beauty) time already?! pt. III

Oh yes, I think it is finally here… Spring Beauty time!!!

2014-02-22 10.47.31Pictured above is an emergingĀ Claytonia “yorkii” plant, found growing in the southern Sierra Nevada at Cross Mountain (Jawbone Canyon) in Kern County almost two weeks ago.

2014-02-22 12.27.47Unfortunately, I didn’t find any plants flowering on this windswept ridge (all were emerging or in bud), so I tried my best not to disturb the ones I did find as I proceeded to dig up a few tubers. I managed to safely transport a few plants to their new homes at Rancho Santa Ana Botanic Garden (where I am conducting my research). To my surprise (I don’t have a green thumb by any means), the buds continued to develop and the first flowers are just beginning to open!

2014-03-05 09.46.18Now if I can just manage to get a few more species into the greenhouse in the near future, I might be able to try a crossing study or two. What I’m really interested in is whether or not these ‘strongly out-crossing’ tuberous perennials are capable of self-pollinating like many of their close relatives (such as in the Claytonia perfoliata complex).

2014-03-03 15.59.52So why should you care, exactly, whether or not it is Claytonia time?!

2014-03-04 12.56.14 Well… you can help me study something really fascinating about Claytonia, that’s why! Send me your pictures so we can get to the bottom of this — How much variation is typical in terms of petal shape, size, and color for a given population of Claytonia?! My collaborators and I have noticed quite a bit of variation among populations of different species, but what may be even more interesting is the amount of variation in petal morphology within populations of a species. It might bend your brain the next time you kneel down and take a look around at the Claytonia blooming in your area. Better yet, take a picture of 50-100 flowers from directly facing the flowers (trying to center the gynoecium in the flower as best as possible), and then compare them (or send them my way). Crazy, right?

2014-03-05 09.43.25This could turn out to be a very interesting experiment indeed šŸ˜‰

…but only if you can get out into the field, and remember to send me your pictures of Claytonia!!! Eastern or Western species of North America, Northeastern Asian species, it doesn’t matter — show off your Spring Beauties!

What are those stamens doing?

1

(Above) How weird is that?!Ā The filaments curl back onto the petals and the anthers shed pollen at the same time that the stigma is receptive in some species of tuberous perennialĀ Claytonia!

4

(Above) In others, the filaments begin to curl back when the anthers start shedding pollen, with the stigma become receptive shortly thereafter. Excellent!

(Below) In this species, the filaments curl back andĀ the stigma becomes receptiveĀ after most of the pollen has seemingly been released. Gnarlatron!

2

(Below) And still in others it seems like the filaments don’t reflex much toward the petals at all. Whoa!

5But what does it all mean?! That is a good question… I’ll have to get back to you on that one.
