Nepenthes 'Joanne Holland'

Originated by Thomas Gibson, Univ. of Wisconsin, Dept. of Botany, Madison, WI 53706. This selection resulted from crossing Nepenthes glabratus x Nepenthes veitchii during 1986. The overall appearance of 'Joanne Holland' is intermediate between the parent species. Plants are vining and branched like N. glabratus, but with larger pitchers with broadly flaring peristomes like N. veitchii. The distinctive pitchers are colorfully red-flecked.

The cultivar is named for Dr. Joanne Holland of Madison, Wisconsin.

Foliar part of leaf is about 22 cm. long, 6 cm. wide, thin, pale green and slightly hairy, with bristled margins. The cultivar has not been seen in flower.
