“…1B), concurring with previous studies reporting L. minor also to be a diploid ( Table 1). The similar appearance, genome sizes, and ploidy levels revealed in this study suggest a close relationship among L. graminifolia, L. longipedicellata, and L. minor with L. minor Fukai et al, 2008;Ge et al, 1987;Hasegawa, 1968;Matsuura and Suto, 1935;Oinuma, 1946Oinuma, , 1949Sato, 1942 L. muscari L. graminifolia var. densiflora 2n = 36 Fu and Hong, 1989;Ge et al, 1987;Zhang, 19982n = 72 Oinuma, 1946Westfall 1950;Zhang, 1998 2n = 112 y Zhang, 1998 L. platyphylla L. muscari, L. muscari var.…”

“…Previous karyological studies have demonstrated the basic chromosome number for liriopogons to be x = 18 (rarely x = 17) with high levels of polyploidy in many species (Table 1). Also, Fukai et al (2008) investigated ploidy level and relative genome size through flow cytometry of six species (plus cultivars) of liriopogons (Table 1). Oinuma (1946) reported polyploid forms of liriopogons exhibited increased vigor and grew over a wider geographic distribution than diploid forms.…”

Liriope Lour. and Ophiopogon Ker Gawl., collectively known as liriopogons, represent important evergreen groundcovers grown throughout the world for their ornamental features and medicinal qualities. As a result of the diversity of desirable traits and evidence of wide hybridization, there is considerable potential for breeding and improvement of liriopogons. However, confusion over taxonomy and proper identification and lack of information on ploidy levels and cytogenetics of individual clones and cultivars have constrained breeding efforts. Objectives of this study were to validate the identification and nomenclature and determine genome sizes and ploidy levels for an extensive reference collection of species and cultivars of liriopogons. Identification was accomplished using existing keys, nomenclature was corrected, and numerous accessions were reassigned based on morphology. Genome sizes were determined by flow cytometry. Ploidy levels for each species were confirmed by traditional cytology. Results confirmed a basic chromosome number of x = 18 for liriopogons with aneuploidy, polyploidy, and cytochimeras found in some cases. The Liriope examined included diploids (L. graminifolia, L. longipedicellata, L. minor, and some of the L. platyphylla), tetraploids (L. muscari and the remaining L. platyphylla), and hexaploids (L. exiliflora and L. spicata). The Ophiopogon studied included diploids (O. intermedius, O. jaburan, O. planiscapus, and O. umbraticola) and a tetraploid/hypotetraploid species (O. japonicus). Monoploid (1Cx) genome sizes varied by genus and species with 1Cx values ranging from 4.27 pg in L. exiliflora to 8.15 pg in O. jaburan. These results clarify nomenclature and taxonomy and provide specific information on genome sizes and ploidy levels of cultivated liriopogons. This information and associated reference collection will aid future taxonomic revisions and enhance efforts to develop new cultivars of liriopogons.

and SHIMOMURA, Takashi : Classification of Trachelospermum cultivars circulated as landscape and ornamental plants in Japan Abstract : Trachelospermum. asiaticum and T. jasminoides var. pubescens are native to Japan and used in many landscaping situations. In addition to wild species, cultivars of this genus are commercially distributed. However, the genetic relationship between cultivars and wild species is unknown and no comprehensive classification has been held regarding Trachelospermum cultivars. In this study, we compared the morphological characters of reproductive and vegetative organs between native species and 35 accessions of cultivars collected from nurseries and plant suppliers. As a result, those accessions were classified into six cultivars of adult T. asiaticum, two cultivars of juvenile T. asiaticum, two cultivars of adult T. jasminoides var. pubescens and five cultivars of juvenile T. jasminoides var. pubescens. From these results we clarified that there are some Trachelospermum cultivars given incorrect commercial names and it resulted in the confusion of their names in the green industry.
