Orobanche / Orobanche fasciculata

I think I have the correct ID for this Orobanche plant - Clustered Broomrape. Not the most photogenic cluster, but I love seeing this plant on very rare occasions.

"Orobanche (broomrape or broom-rape) is a genus of over 200 species of parasitic herbaceous plants in the family Orobanchaceae, mostly native to the temperate Northern Hemisphere.[1] Some species formerly included in this genus are now referred to the genus Conopholis. The broomrape plant is small, from 10–60 cm tall depending on species. It is best recognized by its yellow- to straw-coloured stems completely lacking chlorophyll, bearing yellow, white, or blue snapdragon-like flowers. The flower shoots are scaly, with a dense terminal spike of between ten and twenty flowers in most species, although single in O. uniflora. The leaves are merely triangular scales. The seeds are minute, tan-to-brown, and blacken with age. These plants generally flower from late winter to late spring. When they are not flowering, no part of the plants is visible above the surface of the soil.

As they have no chlorophyll, they are totally dependent on other plants for nutrients. Broomrape seeds remain dormant in the soil, often for many years, until stimulated to germinate by certain compounds produced by living plant roots.[2] Broomrape seedlings put out a root-like growth, which attaches to the roots of nearby hosts. Once attached to a host, the broomrape robs its host of water and nutrients.

Some species are only able to parasitise a single plant species, such as ivy broomrape Orobanche hederae, which is restricted to parasitising ivy; these species are often named after the plant they parasitise. Others can infect several genera, such as the lesser broomrape O. minor, which lives on clover and other related Fabaceae." From Wikiedia.

This photo of Broomrape / Orobanche was taken on 21 June 2015, along the trail to Crandell Lake, in Waterton Lakes National Park.

I was so lucky to be invited to join friends Sandy and Heide on a three-day trip to Waterton Lakes National Park, from 19-21 (inclusive) June 2015. We met up with other members of the Alberta Native Plant Council for their annual Botany Alberta weekend. Most people who attended stayed at the Crooked Creek Campground, a 5.6 km drive east of the Waterton Park Gate on Highway 5, but my friends and I stayed at the Crandell Mountain Lodge on the edge of Waterton town. The ANPC people had a list of species that they hoped to find, and they were very successful.

Our stay down south overlapped the annual Waterton Wildflower Festival, but we came across very few people on our various drives and hikes. Needless to say, I was extremely fortunate to spend three days with people who are very knowledgeable about plants (and other things). This meant that I got to see many wildflower species, including several that were new to me, such as the gorgeous Mariposa Lily. It was one of the flowers that was on my Wish List - and there were hundreds of them to be seen! I had also never seen the spectacular Bear Grass and I was so thrilled that there were still several plants in bloom. Absolutely made my day!

Our two main hikes of the weekend were the Bertha Lake Trail as far as the Bertha Falls (on 20 June), and the Crandell Lake Trail (on 21 June). Makes me smile when a described "short, easy hike" in a book or on the Internet turns into a full day of exploration along the trail, taking hours to reach the destination, though returning to the cars in a much shorter time. Our walks/hikes are very slow-paced with endless stops to look at/for plants and to take photos. This makes it possible for me to go along.

The wind made photographing plants a real challenge, including the beautiful Mariposa Lilies in the meadow along the Hay Barn road. Though I took plenty of photos, I wasn't sure that I would end up with any that were sharp enough. Trying to catch a quick shot when a flower is blowing in and out of the viewfinder is not easy! Unfortunately, I'm no longer able to get down and take macro shots (my lens needs to be about 4" away from the subject), so my photos have to be telemacro.

I've just been trying to find a list of plant species in Waterton Park, but have so far been out of luck. I do have the book, "Wildflowers of Waterton Park" by Jacinthe Lavoie and Ian Wilson, which has an Index of Plant names, but I was hoping to find a list that I could print out.
