Added to the herbarium collection during this period were 14 mounted specimens (total of 7,824). Thomas `Tom' W. Turner (R2A3) submitted two specimens; Julieta Brambila, Entomology Section, Gregory A. Brown (R2A4), Scott D. Krueger (R3A5), Floyd J. McHenry (R1A2), and Amy A. Simington (R2A7) each submitted one specimen which were added to the herbarium. For this period, 110 specimens were submitted for identification, and 727 were received from other Sections for identification and/or name verification (total 837). Some of the samples are described below:

This pin nematode was extracted from tropical peat lumps containing root fragments of this plant and other weeds. The tropical peat originated from peat deposits of drained lakes in central Florida and used for the preparation of potting soil mixes.
Panicum hemitomon (maidencane)- Helicotylenchus dihystera (Cobb, 1893) Sher, 1961, a spiral nematode (Orange County; N01-01055; Wayne W. Smith and Ping Qiao; 19 July 2001). This spiral nematode was also extracted from tropical peat lumps containing root fragments of this plant and other weeds. Pin and spiral nematodes are commonly found in tropical peat containing partially decomposed roots of maidencane and other grasses.
Bromelia sp. (a bromeliad)- Pratylenchus brachyurus (Godfrey, 1929) Filipjev and Schuurmans Stekhoven, 1941, a lesion nematode (Dade County; N01-01115; Karen W. LeBoutillier; 27 July 2001). This lesion nematode was extracted from roots of this ornamental. Pratylenchus brachyurus and P. scribneri Steiner in Sherbakoff and Stanley, 1943 are the most common lesion nematodes occurring on bromeliads.
