Lapeirousia oreogena flowers guide their pollinator to find the way 
Although it seems incredible (as often Evolution is), in the flowers of the South African species, Lapeirousia oreogena (Iridaceae), the clearly visible pattern of six white arrow-markings pointing towards the narrow entrance of the long corolla tube, are visual markings that guide its sole pollinator, a long-proboscid nemestrinid fly, towards a concealed nectar reward.
A study focused on the role of the nectar guides in this species, showed that although the arrow-marking removal has little effect on the approaches by flies to flowers from a distance, it dramatically reduces the likelihood of proboscis insertion.

Here’s one of the many reasons why I grow cacti from the genus Eriosyce. ;) Delightful pink flowers. The body is an interesting reddish-brown colour as well. I’ve been making an effort to treat this plant meaner since it used to look comically bloated with the slightest amount of watering. It could possibly do with a little water, but I like the almost melting-chocolate look it has to it.

Disocactus flagelliformis / Rat Tail Cactus
Timberline Gardens, Arvada, Colorado

While touring the grounds, owner Kelly Grummons mentioned a few of his favorite plants, including this rat tail cactus, which he has had since his youth.  He said it is like a mascot for the nursery - and it is quite beautiful.

Fragile Dapperling

The pictures show a top view and a side view of the mushroom Leucocoprinus fragilissimus (Agaricaceae), a species with wide distribution in many continents, quite characteristic by its shape and color. 

Although the cap of this mushroom is bell-shaped when young, it becomes broadly convex and uplifted in age. The caps are up to 4.5 cm wide, and its surface is translucent-striate from the margin of the disc, pale yellowish white, resembling the paper umbrellas used to decorate cocktails.

Underside the gills are white.The stalk is thick and extremely fragile, pale yellow when fresh, darkening in age, and coated overall with tiny yellowish scales.

Growing strawberries on a trellis is pretty amazing, isn’t it? It sure makes picking them a lot easier.

This is everything I’ve ever dreamed of.

I love this more and more every time I see it.
