1Labelling Three Rock-Crest Plants Without Relying on a Single Character
During a botanical survey of a laterite rock crest in the Eastern Ghats (annual rainfall 900 mm, dry season seven months), four students collect three plants within a 10 m quadrat. Plant P is a mat-forming, 2 cm tall organism anchored by rhizoids; it has a dichotomously branched thallus and, after the first monsoon showers, bears umbrella-shaped structures at the tips.

A nursery manager in coastal Andhra Pradesh is propagating a woody ornamental climber by stem cuttings. Cuttings from the basal 30 cm of vigorous shoots root in 18 days with 78% success, but cuttings from the distal 30 cm root poorly at 12%, even though both are treated with 2,000 ppm IBA and kept at 28 °C and 85% relative humidity.
