Dioscorea alata: Photographed on my property at Shahapur [dead centre in photograph 1, D.bulbifera is to it's left]. It was planted. D. alata can be mistaken for D.bulbifera [plenty of my photographs of which are available in the archives of this group]. According to Dr. Almeida's 'Flora of Maharashtra', one of the main differences between the 2 is that in the former the "stem climbs to the right" [in a clockwise direction - photographs 8 & 9], whereas in the latter, the "stem climbs to the left" [in an anti-clockwise direction]. Also seen are the characteristic 4 - winged / 4 - angled stems [photographs 5 & 6], often with 'bulb-like' tubers [photographs 6 & 7]. Spoke to Dr. Almeida - this plant does not occur in the wild but is cultivated as the "most esteemed yam of Europeans". As it is an exotic, I will be destroying it. Also don't think that ... plant posted a few days ago is D. alata. Nice to see pictures of this Yam. This is the one that is Purple from inside? Sorry to know that you will be destroying it. I would have loved to grow it in our Nasik garden. Please do not destroy it.
Species : Dioscorea alata L. (syn. Dioscorea alata var. purpurea (Roxburgh) A. Pouchet; D. purpurea Roxburgh.) H & H : wild twiner inside a boundary wall, having said thus this does not imply that it was not wild Date : 29/10/12, 10.05 a.m. Place : Hooghly In Photograph 7 it is clearly seen twining around to the right in a clockwise direction. A simple exercise would be to try it yourself with 2 strings and 2 sticks. Thank you ..., I have noted the pic no. 7 (6080,jpg), but had some confusion, for FoP does not have D. alata and D. bulbifera is clockwise in FoP, but ""twining to left" in FoC.
Root Vegetable For ID : Purple : Mumbai : 030514 : AK-7 : 6 posts by 4 authors. Attachments (3). Another root vegetable seen in Mumbai which is purple from inside. Pictures taken on 19/4/14. Would like to know the id please. It looks like sweet potato (Ipomoea batatas) Dioscorea sp Thanks ... Images on searching look like Dioscorea alata, Purple Yam. ..., doesn't seem to be Sweet Potato. Ok thank you. Are they the bulbils or the tubers of Dioscorea alata? There are two types of storage organs. Nobody here sells yam in markets/bazaar. And sweet potato with its varied coloured skin can also look pretty same. Since it is from Mumbai I am not sure. However, D alata var. purpurea meets the criteria, description attached herewith. The question is how long a purple yam can be stored in open air? Climber seen at Lalbagh on 28/7/14. Cultivated, ornamental plant. No flowers. Dioscorea alata. Many thanks for the id of this Climber from Lalbagh. Edible yam: Dioscorea alata Dioscoria For me this looks like a Dioscorea species.

Attachments (2) - 1 & 5 mb. Attachments (1)- 6 mb. ... recently pointed out many type of leaves in this species. Flora of China states: Leaves alternate basally on stem, opposite distally on stem, simple; petiole green or purplish red, 4--15 cm; leaf blade green or purplish red, ovate, 6--15(--20) × 4--13 cm, papery, glabrous, base sagittate to deeply cordate, apex shortly acuminate or caudate. Pl. also see high resolution specimens at GBIF These look like typical cultivated D. alata. Twining direction I noted is anticlockwise in D. alata, clockwise in D. bulbifera. Leaf in D. bulbifera in monsoon becomes huge, nearly orbicular and showy, in summers size gets reduced drastically......... it would be interesting to record them in summers and compare with what we see in rains.
