Changing name to reflect the actual size of this material. -SBL 4/7/2015] According to the SSR study by Lattier et al. (2022), this accession is tetraploid and clustered together with another tetraploid identified as C. gotoana 'March Jewel', which was introduced by Camellia Forest as a dwarf cultivar; together, they were found near another cluster containing mostly hexaploid C. spicata, as well as some pentaploids that might represent hybrids between the two species. Based on the evidence, it appears that this is closely related to 'March Jewel', a dwarf selection of C. gotoana that was introduced by Camellia Forest; it is possible that this accession is actually an overgrown 'March Jewel', but it is clearly not dwarf. Its close relationship to C. spicata shown by the SSR markers may simply align with other studies that suggest C. gotoana and C. spicata share the same karyotype and appear to be closely related; based on that, this may be the only true C. gotoana in USNA collections at this time. -SBL | 2147967 | NA 67499 |

Its close clustering with 'Longwood Chimes' (NA 70027-H) strongly suggests that this material derives from the same source material as NA 53233, which was collected in the wild by Dr. Clifford Parks and from which 'Longwood Chimes' was made a named cultivar after distribution of seedlings to Longwood Gardens.

This material agrees with C. glandulifera as recognized in the Flora of China. The lone individual of this accession has been selected at USNA for evaluation as a potential cultivar based on its unusually good floral and habit qualities; its flowers are a bright, rich yellow color with a strong primrose/lemon fragrance and are borne densely along the branches in compact, dense clusters; the branches are especially stout and thick relative to many other Corylopsis, and the plant maintains a rounded, compact habit with pleasing zig-zag stems. The leaves are an attractive dark blue-green color with thick substance when grown in adequate sunlight. According to the SSR study by Lattier et al.

According to the SSR study by Lattier et al.

'Winterthur', and another odd diploid identified as C. glandulifera; there is a chance that all of these are hybrids between C. pauciflora and diploid forms of either C. glabrescens or C. gotoana. -SBL | 2144619 | NA 37205 |

Four plants (from cuttings) from Brookside in March 1985 [We may have distributed one of the Hillier plants to Brookside early on, and the plants in the Asian Collections may not be genetically identical to the plant on the bank along Hickey Lane. They do seem to be a bit different, the Asian Collections plants being more fragrant and robust. -SBL] This accession was reidentified as C. sinensis Hemsl. var. calvescens Rehd. & Wils. by Peter Mazzeo and Frederick G. Meyer according to a 7/27/1987 identifications sheet; at that time, current revisions lumped a number of distinct taxa (like C. platypetala and C. veitchiana) together under this name. According to the SSR study by Lattier et al. (2022), NA 36588 (including sampled 36588-H, -CJ, and -CL) is tetraploid and clustered together with good bootstrap support with a group of other 4x individuals mostly identified as C. platypetala, and separate from other C. gotoana (including C. gotoana var. coreana). -SBL | 2144590 | NA 36588 |
