Abstract:

Narrowly lanceolate leaves occur frequently in the genus Aster. It was often employed as a distinguishing character in the taxonomy of this genus. The origin of this particular leaf shape, however, has never been investigated using comparative methods. In this study, we reconstructed a comprehensive phylogeny that includes most species of Aster with narrowly lanceolate leaf. We then gathered data on riparian habitats and the presence or absence of narrowly lanceolate leaves, and investigated the evolutionary association between them in a phylogenetic context. Our analysis indicated that the sp

Abstract:

Randia lanceolata and R. stenophylla (Gardenieae, Rubiaceae) are found to be conspecific and here transferred to the Philippine endemic genus Villaria (Octotropideae), and the new combination is here proposed. Villaria lanceolata is distinct from the other six members of the genus in showing a rheophytic habit and possessing narrowly lanceolate leaves, red fruits when ripe and prominent parallel ridges along the fibrous exostesta cells. The new member of Villaria is here comprehensively described, illustrated and typified.

Abstract:

Heterophylly is the phenomenon of leaf forms varying along the longitudinal axis within a single plant. Populus euphratica, a heterophyllous woody plant, develops lanceolate leaves and dentate broad-ovate leaves on the bottom and top of the canopy, respectively, which are faced with different intensities of ambient solar radiation. However, the mechanism of the heteromorphic leaf response to the microenvironment in P. euphratica remains elusive. Here, we show that the dentate broad-ovate leaves have advantages in tolerating high light intensity, while lanceolate leaves are excellent at capturi

This species is now being reported for the first time from the Nilgiri Hills. It is characterized by a pleurocarpous habit, erectopotent stems, and hamate, hooked, and lanceolate leaves that are densely arranged along the stem. The leaf cells are multi-papillose. This species differs from Macromitrium nepalense in having hamate, lanceolate leaves and multi-papillose mid-laminar cells.

Abstract:

Stellaria multipartita sp. nov. (Caryophyllaceae) from Chongqing, China, is described and illustrated based on morphological and molecular data. The new species is similar to S. radians by the palmately fimbriate petals with more linear divisions. Different characters are: shape of the leaves (oblong-triangular to ovate-triangular vs. oblong-lanceolate to ovate-lanceolate in S. radians), petals (10–12-cleft vs. 5–7-cleft in S. radians), and seeds (with mamillate ornamentation vs. scrobiculate ornamentation in S. radians). A molecular phylogenetic analysis supports the recognition of Chongqing
