Scarlet/ Lemon Bottle Brush;

As has been clearly specified in Trees of Delhi (Pradip Krishen) none of the specimens grown in Delhi belong to C. citrinus. They actually belong to C. viminalis (Soland. ex Gaertn.) Cheel., the two similarly looking species are distinguished as under:
C. viminalis: Tree with drooping slender branches; leaves linear-lanceolate, up to 10 cm long and 4-7 mm broad; flowers scarlet--red in up to 7 cm long dense spikes; filaments united at base; fruits not persisting on old wood.
C. citrinus: Shrub or tree with short arching branches; leaves broadly lanceolate, rigid, up to 7 cm long, 6-12 mm broad; flowers scarlet red in up to 10 cm long spike; filaments free at base; fruits persisting on 2--3 year old branches.

The Weeping Bottlebrush tree [C.viminalis] is larger than the Red Bottlebrush tree [C.citrinus], but is mainly differentiated from the latter by having stamens that are united in a ring at the base [whereas in the latter the filaments are free]. 

Differences between C. citrinus and C. viminalis:
--C. viminalis has longer, more weeping branches. It is generally a tree of moister, wetter soils and climates. Bark is distinctly furrowed, with corky ridges. Inflorescences are longer, to approx. 15cm in length. Flower color is typically dull, light red, though pink and some darker red forms exist.
--C. citrinus is generally shrubby, though can reach small tree (to 8-9 m) status in favorable, dry sites. It does not thrive in moist, humid climates. Bark is tight, flaky, and can be peeled easily in long strips. Inflorescences may be erect to nodding, seldom completely pendant, to approx. 10-12 cm in length, 2/3 as wide. They are typically bright red, more densely packed on the stem than C. viminalis. Color forms in mauve to purple also exist.

Attached are pictures of Callistemon citrinus captured at Ooty in November 2013.
Earlier posted on the forum and were identified.
dx of citrinus without leaves?
I think C. rigidus
so many persistent fruits, stiff leaves
i meant leaves at the top/distal end of the flower spike? do they play a role in diagnosis?
There might be some confusion, this was earlier identified as C. citrinus by yourself here
Could you please have a relook?
This should be C. citrinus only as leaves are shorter and lanceolate.
 
Requesting to please ID this cultivated tree captured in Ooty in November 2013.
Is this C. rigidus?
Should be C. citrinus, old fruits persistent and lanceolate leaves.
Thank you ... for the ID..
