| 0 | NA 87164 | (crested selection) | Cyrtomium falcatum (L. f.) C. Presl | | NA | | Not Available | 2022 | | | | | | | Clone | Full name as recorded at U.S. National Arboretum: Cyrtomium falcatum (crested selection). A single "sporeling" (or more likely, a mutation of one) formerly recorded under NA 69370-H that was discovered on 7/20/2022 to have ornamentally crested tips, a phenomenon possibly not seen before in this species; it is highly ornamental. All of the plants received from USBG and accessioned under the old number were grown from spores of 'Rochfordianum', but none are alike. This plant may not have had crested leaves initially, and could even have developed them more recently. Information from the parent accession, NA 69370: USBG98-1109 through 98-1122 excluding 98-1117; all from the same seed/spore source. [Note: although they evidently arose from spores of a plant labeled 'Rochfordianum', all of the plants in this accession alive in 2022 are quite different in appearance, with few (if any) resembling 'Rochfordianum'. One bears crested tips, which appears to be novel for this species at this time, and will be reaccessioned as NA 87164 and treated as a selection. -SBL] | 2155202 | NA 87164 |

[Note: although they evidently arose from spores of a plant labeled 'Rochfordianum', the few plants remaining alive in 2022 are not identical in appearance and cannot be said to be identical to 'Rochfordianum'. One individual has been discovered to produce crested tips, which appears to be a novel trait for this species at this time, and that plant has been reaccessioned as NA 87164 and treated as a selection. -SBL] | 2148366 | NA 69370 |

Presl | Honshu, Japan | NA | | Not Available | 1978 | COLLECTED | 10/17/1978 | Ishikawa Prefecture: Noto Peninsula: Saruyama. | | 91 | Semi-shade. Elevation: 300 feet. | Wild material | Full name as recorded at the U.S. National Arboretum: Cyrtomium falcatum subsp. littorale. The only plant growing next to the 44948-H label in 2022 is actually C. fortunei, and it appears that this accession and NA 45190 were mixed up during a temporary relocation to the lath, after which they were replanted but spread around the Cryptomeria Walk. One plant in BON-CRYP-L that is probably this accession (and not NA 69370) is quite compact, and one in BON-CRYP-R has particularly smooth pinnae. Further examination pinpoints this accession as C. falcatum subsp. littorale, which produces more spores per sporangium (supposedly 64, although ours seem to have many more than that) and has smaller laminae that are hard-leathery and rather thick compared to typical C. falcatum. | 1953614 | NA 44948 |
| 6 | NA 45190 | NA 45190 | Cyrtomium fortunei J. Sm. | | NA | | Not Available | 1978 | | | | | | | Wild material | Full name as recorded at U.S. National Arboretum: Cyrtomium fortunei. Several plants had originally been planted on the terrace side of the Cryptomeria Walk in the National Bonsai and Penjing Museum, along with plants of C. falcatum NA 44948. Some or all were apparently dug and planted in the lath temporarily, and then replanted in the Cryptomeria Walk, prior to 2003. I noticed that the plant found growing with the 44948-H label was actually C. fortunei, not C. falcatum (it has pale green, papery leaves), and since the collectors were perfectly familiar with the differences and collected both species during the expedition, it is evident that the plant is really a second individual of 45190 (and has now been reassigned to 45190-J). The plant that was relocated in BON-CRYP-R after being in the lath had the 45190-H label and is correctly identified. -SBL | 2145151 | NA 45190 |
