Black knot fungus

This knotty, black growth on a tree branch is black knot fungus (Dibotryon morbosum). It infects cherry, plum, apricot and chokecherry trees and kills the infected part of the tree and provides a habitat for insects. Treatment is fungicides and cutting the affected branch several centimetres below the infected site.

Having a look in the hindgut of termites

If you get a chance to go to Yosemite by car, you should see an insane number of rotten logs in the woods. A ranger explained to me that it’s because of a snow storm causing toppling of trees. All those logs on the floor are progressively rotting and eventually in spring will form a…

Polyad Pollens of Madras Thorn or Manila Tamarind (Pithecellobium dulce)

Polyad is a type of pollen arrangement in which many pollens are joined together to create round structure. Pithecellobium dulce pollens are polyad. In Mumbai, near my house, Madras Thorn or Manila Tamarind is flowering right now. I collected its flowers and took pictures using Foldscope. Pollens look beautiful, each polyad must be around 30-50…

Cells of red leaves of Poinsettia

The bright petals of Poinsettias, which look like flowers, are actually the bunch of upper leaves of the plant, called bracts. Poinsettia flowers are small, green or yellow, and grow inconspicuously in the center of each leaf bunch. The ancient Aztecs (the Mexican Indians) prized the Poinsettia as a symbol of purity. Centuries later, Mexico’s…

To the many Foldscoping thrills ahead of me in Cape Town! If you were to tell me a year ago that I’d be in Cape Town for a quarter off my university studies, I probably would’ve looked left and right, then accepted my ignorance by saying “Uhh, what? Where exactly is Cape Town, and what’s…
