Vidi specimina viva spontanea numerosa. 
The depth to which the calyx is divided is variable, 
This plant like many others which have a wide range in altitude upon the Himalaya has a high-level form and a low-level 
form so distinct in habit that the gardeners near Darjeeling believe them two species, and there are traces in the Calcutta Herbarium of 
several attempts to subdivide this species. 
The low-level plants have the corolla whitish-lilac with an elongated tube and a very loose panicle : the high-level plants 
have the corolla dark violet-purple with a shorter tube, and the flowers almost fasciculate towards the ends of the panicle branches. There 
is a zone of country between the high-level and low-level forms from which the plant is generally absent. This is the case with some 50 
Sikkim plants which have a high-level and a low-level form separated by «a barren area, viz., the region of cultivation. The Lepchas like 
to live entirely between 2000 and 5000 feet elevation in outer Sikkim. Up to 2000 feet the dry Sal Forest extends : above 5000 feet comes 
in the giant dripping forest. In the region of cultivation between, many plants are wanting though found plentifully both above and be- 
low it. As another striking example I may mention the fern Angiopteris evecta which grows a gigantic size in the upper wet forest, but 
has quite a different aspect in the lower forest and is considered by the Lepchas (as well as by some botanists) a different species alto- 
gether.
