فَقْرَةٌ

2.
Accord. to the K, it signifies also A certain plant; and its plural [or rather the coll. gen. n.] is فَقْرٌ: but the singular [or n. un.] is correctly فَقُرَةٌ, with fet-h and then damm, mentioned by Sb as a word of a rare form, of which the plural [or coll. gen. n.] is فَقُرٌ, as it has no broken plural; and explained by Th. (TA.)
