Diagnostic characters of Clematis armandi
Clematis armandi is widely distributed in China, Myanmar, and Vietnam. In China, it occurs in Chongqing, southwestern and northern Fujian, southern Gansu, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, southern Shaanxi, Sichuan, eastern Xizang, Yunnan, and southern Zhejiang ( Huang et al. 2024b). Morphologically, this species is well characterized by being woody vines and by having ternate leaves, leaflets entire, ovate-lanceolate, oblong-ovate to ovate, glabrous on both surfaces, conspicuous scales of axillary buds often present at the base of cymes, pedicels not bracteolate, stamens glabrous, filaments not rugose, anthers narrowly oblong to linear (Chang 1980, Wang & Bartholomew 2001, Huang et al. 2024b). Moreover , C. armandi is a spring-flowering species, usually in full blossom from March to April. The type specimens of C. armandi and five non-type specimens from the type locality, i.e. Baoxing county in western Sichuan, are shown in Figures 22 View FIGURE 22 , 23 View FIGURE 23 . It is to be noted that although the presence of large scales at the base of cymes is one of the most important diagnostic characters of C. armandi , this character often does not occur or at least is not conspicuous on some branches, particularly on those of current year ( Huang et al. 2024b; Fig. 22A–D View FIGURE 22 ).
All these diagnostic characters of Clematis armandi have been confirmed by our observations of living plants within the six populations we visited in 2024 ( Table 1 View TABLE 1 ; Figs. 6–21 View FIGURE 6 View FIGURE 7 View FIGURE 8 View FIGURE 9 View FIGURE 10 View FIGURE 11 View FIGURE 12 View FIGURE 13 View FIGURE 14 View FIGURE 15 View FIGURE 16 View FIGURE 17 View FIGURE 18 View FIGURE 19 View FIGURE 20 View FIGURE 21 ). The plants are woody vines; leaves are ternate; leaflets are entire, ovate-lanceolate, oblong-ovate to ovate, glabrous on both surfaces; large scales of axillary buds are present at the base of cymes borne on branches of last years, but often absent on branches of current year; pedicels are not bracteolate; stamens are glabrous, with filaments not rugose, anthers narrowly oblong to linear. The plants are usually in full blossom from March to April.
