The typical form of Borreria latifolia has glabrous stems, glabrous or pubescent sheaths, leaves more or less scabrid or shortly puberulous on the upper leaf surface and pilosulous to pilose on the lower surface or with the lower nerves pubescent. Sometimes the leaves may be glabrous above, but more commonly are scabrid above. The stems are usually erect, but may be sprawling or even prostrate. Blue- and lavender-colored corollas are sometimes found in collections of B. latifolia (Wurdack & Adderley 42660; Forest Service of French Guiana 4079, 5080).
