“What’s that flower?” The Family asked me as I was stalking a Ceropegia. I looked around at the pentagonal white shapes on a stalk that was about 20 centimeters high. “I don’t know”, I said, as I took a photo for later reference. She soon found that it was not a flower. A flower has sexual organs, and this did not have any. Mandar explained that it was the opened fruit of the Dipcadi montanum. I’d posted about this plant from the Hyacinth family last year after a single sighting.

Dipcadi montanum fruit and flower

This year I’d seen it several times. In fact just a few minutes before I’d seen another stalk which had started fruiting. You can see the fruit towards of the bottom of the stalk in the photo here: a dark green knob. The chance sighting I had last year was of the D. montanum plant standing in a field of bladderwort (Utricularia). Each sighting this year showed the same thing. In fact, the purple spots which you see in the featured photo are purple bladderwort. The linkage between the two just got stronger in my mind because of this statistical improvement. Typically the bladderwort grows in poor soil, and gets nourishment from digesting small insects. There is evidence of a rich ecosystem which grows inside the bladder. Does this ecosystem produce benefits to the thin soil around it which are reaped by the bulbs of the Dipcadi? I don’t see anything written about it.

Dipcadi montanum

I got a sharp photo (above) of a flowering Dipcadi on the nearby lateritic plateau of Chilkewadi. The spots of white that you see in the photo are of globular pipewort (Eriocaulon sedgewickii). These are known to grow in association with bladderwort. In fact the field had some, although they do not appear in the photo. The triple association of Dipcadi, bladderwort and pipewort is very strong, and cries out for an explanation.

Plateau of flowers

I’ve written about the world heritage Kaas plateau before. I went back there over the weekend. The volcanic rock barely holds any soil, and what little is there has little nutrient. The plants that one can see here have evolved in this hard environment. As a result, this 10 square kilometer area at an altitude of about 1.2 kilometers is an island mountain: the flora here is isolated from flora in other plateaus in the region. There’s a brief but glorious flowering at the end of the monsoon. By all accounts the flowers change almost every week.

Kaas plateau: landscape

The most famous plant here is the Topli Karvi (Strobilanthes sessilis) which blooms in mass once every seven years. Last year this was in bloom. This year the general view (see photo above) did not show any of the bright blue flowers of this bush. One had to search hard for the few isolated and idiosyncratic bushes of S. sessilis which flowered this year. Instead the landscape was full of patches of white globular pipewort (Eriocaulon sedgewickii) mixed in with the vivid colours of the carnivorous purple bladderwort (Utricularia purpurascens). In other places we patches of the yellow sonkadi (Pentanema indicum) mixed in with the violet rosemary balsam (Impatients oppositifolia). You can see all four species in the featured photo.

This week the balsam outnumbered everything. Most green patches had highlights of violet. Maybe by next week the sonkadi will dominate.
