It is interesting to observe the changing face of flora in Sanjay Gandhi National Park, Mumbai. Last month a small open area below Kanheri Caves was covered by lovely blue flowers of Neanotis montholoni amidst growing spikes of Silver Spiked Cockscomb and the much smaller Common Small Justicia flowers. Yesterday almost the entire area has erupted with the taller plants of the gregarious Common Balsam, Impatiens balsamina. I did not see any N.montholoni flowers.

 

Isaac Kehimkar calls it succession of flowers. If conditions for one species is ideal then that species takes over and rapidly spreads itself smothering other species.

Good observation, Kiran ji,
 
Here are some extracts from Wikipedia link on Impatiens balsamina (Garden Balsam or Rose Balsam): http://en.wikipedia.org/wiki/Impatiens_balsamina

Impatiens balsamina (Garden Balsam or Rose Balsam) is a species of Impatiens native to southern Asia in India and Myanmar.It is called kamantigue in the Philippines.[1]

It is an annual plant growing to 20–75 cm tall, with a thick, but soft stem. The leaves are spirally-arranged, 2.5–9 cm long and 1–2.5 cm broad, with a deeply toothed margin. The flowers are red, pink, purple, or white, and 2.5–5 cm diameter; they are pollinated by bees and other insects, and also by nectar-feeding birds.[2]

Different parts of the plant are used to treat disease and skin afflctions; the leaves, seeds, and stems are also edible if cooked. Juice from balsam leaves treats warts and also snakebite, while the flower can be applied to burns to cool the skin.[3]

It is widely cultivated as an ornamental plant, and has become naturalised and invasive on several Pacific Ocean islands.[4]

Dear Kiran

Your observation at SGNP may be termed as 'succession'.

However, the description that you have given for meaning of
'succession' is not correct. When different seasonal plant species
emerge, flower, fruit & die in a short span, and allow some other
plant species to emerge and grow, one after the other that is called
'succession'. You can see this at Valley of Flowers where the summer
season is very short and gives very liittle time for all seasonal
plants to complete their life cycle. Here various plants have evolved
to grow in succession in the same region. Their span of life cycle
also becomes short. In a way they create their own seasonal niches
and keep evolving. You should observe the VOF for a longer duration
and you will be able to see amazing dynamic succession of plants.
There is change in flowering pattern, almost every fortnight.

However, when plants take over the region and do not allow the
original vegetation to grow, it is called 'invasion'. That is how
weeds take over even forest patches.

Best wishes

Appears more closer to images at Neanotis lancifolia (Hook.f.) W.H.Lewis rather than those at Neanotis montholonii (Hook.f.) W.H.Lewis
