Elaeagnus indica Servett. (Endemic to Andhra pradesh, Karnataka, Kerala and Tamilnadu- Flower, fruit- March to June) Elaeagnus latifolia L. (S-India, Sri Lanka, Myanmar [Burma] (Bago, Kachin, Kayin, Mandalay, Sagaing, Shan, Yangon), Malesia, Andamans (Middle Andamans, South Andamans), Nicobars (Central Nicobars, Great Nicobar Isl., Little Nicobar Isl.), Pakistan (I), Bangladesh as per Catalogue of Life)- Karnataka, Kerala, Orissa and Tamilnadu- Flower, fruit- November to March) Confusion in Elaeagnus species in Flora of Peninsular India : 11 posts by 3 authors. Flora of Peninsular India gives the following species with details as below: Elaeagnus indica Servett. (Endemic to Andhra pradesh, Karnataka, Kerala and Tamilnadu- Flower, fruit- March to June) Elaeagnus latifolia L. (Syn: Elaeagnus conferta Roxb.; Elaeagnus kologa Sch. in DC.) (S-India, Sri Lanka, Myanmar [Burma] (Bago, Kachin, Kayin, Mandalay, Sagaing, Shan, Yangon), Malesia, Andamans (Middle Andamans, South Andamans), Nicobars (Central Nicobars, Great Nicobar Isl., Little Nicobar Isl.), Pakistan (I), Bangladesh as per Catalogue of Life- Karnataka, Kerala, Orissa and Tamilnadu- Flower, fruit- November to March) I could not find the difference between the two on net. I could not find the difference between the two on net. Can someone solve this mystery ? What are the observations in Flora of Maharashtra ? In one of the resources that I refer to - the entry is as follows: Elaeagnus infundibularis Momiy. (= Elaeagnus latifolia auct non L.; Elaeagnus conferta Roxb.) Reference: The Gazetteer Department - महाराष्ट्रातील वनस्पतीशास्त्र आणि वनसंपदा I am not aware of contents in Flora of Maharshtra. Thus there is some connection of Elaeagnus latifolia auct non L. with E. conferta Roxb. in Flora. In sites like The Plants List, POWO, GBIF, the listing could be different. Thanks, … I think Flora by Almeida ji may be of some help in this matter. Useful Tropical plants on Elaeagnus latifolia says as below: Elaeagnus latifolia, Elaeagnus conferta and Elaeagnos triflora are sometimes treated as three distinct species and sometimes as a single entity (under Elaeagnus latifolia). There is also disagreement over the range of the species, with Elaeagnus latifolia variously stated to be native to the Indian Continent or to continental southeast Asia. In this treatment the three are treated as distinct, following the Flora Malesiana. Many taxa in this genus are separated only by quantitative characters, and better information on population variation is likely to lead to a significant reduction in the number of species recognized. Indeed, recent studies (Du, Fl. Yunnan. 12: 749-776. 2006) suggest that some species of Elaeagnus should be combined. Synonyms given are as below: Elaeagnus infundibularis Momiy. Elaeagnus kologa ceylanica Servett. Elaeagnus kologa grisebachii Servett. Elaeagnus kologa macrophylla Servett. Elaeagnus kologa wightii Servett. Elaeagnus punctata |
