FIGURES 3–10. Champia farlowii sp. nov. 3. P.B.-A. no. 592, as Champia parvula, from Massachusetts (Collins et al., 1899). Scale bar = 4 cm. 4. Holotype specimen [EC059] from Charleston, Rhode Island. Scale bar = 2 cm. 5.

Cortex of node showing complete lower layer and incomplete outer layer [CWS 09-39-7]. Scale bar = 50 μm. 7. Axial view showing branch originating in internode (arrow) [CWS 1318]. Scale bar = 100 μm. 8. Surface view showing tetrahedral sporangia in outer cortex [CWS 1318]. Scale bar = 50 μm. 9. Nodes showing one and many clustered cystocarps [CWS 1029]. Scale bar = 500 μm. 10. Longitudinal section of cystocarp demonstrating the 'tela arachnoidea' formed between carposporophyte (not shown) and pericarp wall [CWS 1029]. Scale bar = 500 μm.
