“ I believe there are 28 speciess and one family of bromelidads : Brewcaria sp. Maybe it is in Wikipedia. Now there are botanists naming a probable new family of plants I collected, a new species of Utricularia I pick up at Ptari-tepui and a new species of algae from Chimanta tepui.” - Charles Brewer-Carías
Concerning his fascinating research into the feeding structure of the carnivorous plants, genus Heliamphora, also known as sun pitchers, Charles said the following, quote -
“What I really found and discovered happened at Cerro de la Neblina in 1971, when I was the first one to stop in front of an Heliamphora and guessed how the insects were attracted and let them get wet and sank due to a lower surface tension at the water due to some saponin. Then at the boyom of the pot were some filarias that would digest the insect bodies and the plant then feeds with the filarias excrements... Then I was able to determine how the water of the cup would not flood the cup while raining and how the plant kept the level of the water tank in certain place due to some siphon procedure with some bristle hairs organized like a brush that acted by capillary. This I observed using the blan indian drawing ink from G.C.K. Dunsterville, the botanist and painter of orchids that was my fellow companion. Until then, all the botanista had studied the plants flat pressed between newspapers....
All this I explained in two humble articles that has been cited by many authors.”- Charles Brewer-Carías
