365Caws is now in its 14th year of publication, and was originally intended to end after 365 days. It has sometimes been difficult for me to find new material, particularly during the winter months, but now as I enter my own twilight years, I cannot guarantee that I will be able to provide daily posts. It is my hope that along the way I may have inspired someone to a greater curiosity about the natural world. If so, I can rest, content in the knowledge that my work here has been done.

The Icing On The Cake
Day 259: Yesterday, I introduced my readers to two of the most common species of Paintbrush to be found in Mount Rainier National Park. Today, it is my pleasure to show you a rare variety.
First, I want you to notice that I used the word "variety" in that last sentence. This is not a rare plant, per se, but it is a rare colour. Just like pansies, petunias and poppies can be found in a variety of colours, so can some of our native wildflowers. Their genetic differences are not sufficient to categorize them as separate species or even as sub-species despite the fact that they are visually quite different from others of their same species.
Castilleja parviflora var. oreopola is a case in point. This "Magenta Paintbrush" has white bracts. If you compare a "leaf" of magenta-coloured Paintbrush (C. parviflora) to a "leaf" of this white Paintbrush, you should be able to tell that they are identical in all respects except colour. The white form is rather rare in the Park, previously reported from the Sunrise area. Following a lead from a botanizing friend, I was pleased to be able to observe not one but two specimens near Paradise on a morning hike today.
