Reflectance Measurements of Glossy Petals of Ranunculus lingua (Ranunculaceae) and of Non-Glossy Petals of Heliopsis helianthoides (Asteraceae)

Abstract: A spectrophotometric comparison of the reflectance of glossy petals of Ranunculus lingua (Ranunculaceae) and non-glossy petals of Heliopsis helianthoides (Asteraceae) was made in relation to the angle of incidence of the incoming light. Additionally, the reflectance of petals of R. flammula, R. acris and R. repens (Ranunculaceae) was measured for comparative purposes. In the examined Ranunculus species, gloss is present around mirror geometry over the whole spectral range measured, including the UV region where it accentuates the UV peak, and even at the basal UV-absorbing area of the petals. According to a colour hexagon evaluation of the reflectance data, these gloss phenomena diminish the colour contrast of the petal against the background. Nevertheless, due to their brightness, they may serve as an attractant or predictor for pollinators and other visiting insects, possibly acting as a beacon while approaching the flower. The position of the reflectance maximum in the UV around 340 nm is in accordance with the sensitivity maximum of the UV photoreceptor of potential pollinators like Apidae. The mean reflectance values of the four examined Ranunculus species do not show any clear correlation with their anatomical make-up     

Characterization of seven polymorphic microsatellites for the study of two Ranunculaceae: Ranunculus nodiflorus L., a rare endangered species and Ranunculus flammula L., a common closely related species

Ranunculus nodiflorus and Ranunculus flammula are two closely related Ranunculaceae. In France, the first one is rare and endangered, whereas the second is common. To compare their population genetic structure, seven polymorphic microsatellite markers were characterized. We found no polymorphism in R. nodiflorus, whereas R. flammula was polymorphic at each locus. The total number of alleles per locus varied from three to eight. Observed heterozygosities ranged from 0 to 0.261. This set of microsatellites offers an efficient tool to study population genetic structure and to compare the results between closely related endangered and common species.

禺毛茛复合体及其近缘种过氧化物酶同工酶研究

对国产禺毛茛（RanunculuscantoniensisDC．）复合体及其近缘种8个种的15个居群52个个体的根进行了过氧化物酶同工酶研究,结果表明：①居群内过氧化物酶谱略有变异。同工酶酶谱或多或少能显示居群特征。供试的8个种中没有任何2个种的酶谱完全一致,这说明在种级水平酶谱呈现出高度的分化现象。②根据染色体、孢粉和过氧化酶同工酶的资料推测,除R．silerifolius（2x）外,R．cantoniensis（4x）还有1个亲本。该亲本应具有“短m-型”染色体组,散沟和波状覆盖层的花粉,在其根的过氧化物酶酶谱中至少含A1、A2、C4和C64条酶带。③来自形态、染色体孢粉及同工酶的证据均证实R．vaginatus（5x）可能起源于（R,diffusus（4x）×R．sieboldii（6x）的杂交后代。     

Ranunculus ailaoshanicus W. T. Wang,a new species of Ranunculaceae from Yunnan,China

Ranunculus ailaoshanicus W. T. Wang, a new species of the Ranunculaceae from Yunnan, China, is described and illustrated. This species in habit shows striking resemblance to Ranunculus dongrergensis Hand.-Mazz., and differs from the latter in its lower leafless scapes, smaller flowers, and smaller, oblong-elliptic petals with obscure nerves. In R. dongrergensis, the stems are 5–15 cm tall and bear cauline leaves, the flowers are larger, 1–1.8 cm in diam., and the petals are larger, obovate in outline, 4–9 mm long, 2.2–7 mm broad, and nervose.
