MS Oct, 2019/14 Citrus sp. (macroptera?) for ID : 4 posts by 2 authors. Attachments (4)
Location : Near Mawmrang, Mizoram

Altitude : ca 1,500 m.
Date : 06-11-2019
Habit : Shrub or small tree
Habitat : Wild
Shape of the fruit is confusing me although leaves and other aspects appears similar to Citrus macroptera as per
But some images how similar shape as per
Wikipedia states as below:
The species is sometimes divided into four varieties, or alternatively into three separate species, as follows:[5]
  • C. macroptera var. macroptera
  • C. macroptera var. annamensis Tanaka -> C. combara Raf.
  • C. macroptera var. combara (Raf.) Tanaka -> C. combara Raf.
  • C. macroptera var. kerrii Swingle -> C. kerrii (Swingle) Tanaka
Pl. check.
On further checking, it is given as a syn. of Citrus hystrix DC. by Catalogue of Life.
Images on Google seems to match with it.

Going by keys between this (Citrus macroptera syn. of Citrus hystrix DC. as per POWO) and Citrus ichangensis (syn. of Citrus cavaleriei H.Lév. ex Cavalerie as per POWO) at BSI Flora of India and Flora of China and details, it appears to be Citrus cavaleriei H.Lév. ex Cavalerie.

Citrus hystrix?:
Can anyone confirm that this is Citrus hystrix ?
It was found growing deep inside almost virgin forest, one full day’s walk from the nearest village, on Khayangphung Mountain, Ukhrul District, Manipur at approx’ 2000m asl.
In theory it is possible that the plants seen here have become naturalised from discarded seeds left by hunters as the area has been used previously as a camp.

Efi site link: Citrus hystrix

Based on key in Flora of China first looks more likely
Leaf blade margin entire to finely crenulate, apex acuminate. 2 C. cavaleriei
+ Leaf blade margin conspicuously crenulate, apex obtuse to subrounded and sometimes mucronate. 3 C. hystrix

citrus species from Phenk (Nagaland) : 2 posts by 2 authors. Attachments (1) – 4 mb.
Please identify the citrus species from Phenk (Nagaland)

I think Citrus hystrix as per images and details herein.

Going by keys between this (Citrus macroptera syn. of Citrus hystrix DC. as per POWO) and Citrus ichangensis (syn. of Citrus cavaleriei H.Lév. ex Cavalerie as per POWO) at BSI Flora of India and Flora of China and details, it appears to be Citrus cavaleriei H.Lév. ex Cavalerie.

This looks like Citrus hystrix. Citrus cavaleriei is a native of China. I don’t know if it is cultivated here.

It is distributed in Evergreen forests of the E.Himalayas, Arunachal Pradesh and Nagaland; S.W. China as per BSI Flora of India (Citrus ichangensis Swingle).

Keys and details clearly indicate this.

Okay …,  I did not know about its distribution in East Himalaya.
The plant specimen of Citrus shown by … in Nagaland is Citrus ichangensis not Citrus macroptera. The fruit characteristics  of Citrus macroptera are different shown in Photograph. The Taxonomy of citrus is confusing. In my publication of Systematic Pomology, we have tried to update it.
