Another entry from Taisha today:
Today’s picture is of Ipomoea pileata. Thank you to a regular contributor to the Botany Photo of the Day Pool, Bart Wursten (aka zimbart@Flickr). This photo was taken on April 30, 2013 in Gorongosa National Park, which is in Mozambique’s Sofala Province.
The large boat-shaped bracts of Ipomoea pileata are what caught my eye– the pink (to white) funnel-shaped flowers just pop right out. This species is an annual or perennial twining herb with ovate leaves that are cordate, or heart-shaped, at the base. The stem can reach up to 3 meters long and grows from a thick taproot.
This species is in the Convolvulaceae, or the morning-glory family. The genus Ipomoea is the largest within the family, with over 500 species. A familiar member in this genus is Ipomoea batatas or the sweet potato.
