Cortesia is a halophytic and monotypic genus endemic to Argentina that belongs Ehretiaceae (Boraginales). It morphologically distinct from the other members of family in having cuneate leaves with 3-dentate apex, an involucrum fused bracts, spatulate calyx lobes, white drupes two-parted endocarp. Its single species, cuneifolia, here treated illustrated based on study numerous herbarium collecti...

Improved knowledge of Dipsacales phylogeny provides a solid framework for studies of character evolution. Although the polarity of many characters can now be confidently established, for others it remains unclear. This results largely from uncertainty about the broader relationships of Dipsacales and is especially problematic for characters that differentiate the two basal lineages, Adoxaceae a...

The effects of Silver Thiosulphate (STS) and Naphtalene Acetic Acid (NAA) (0,45%NAA+1,2% NAA-amide at 500 mg.l) on flowering bud development, anthesis duration, bract longevity and bract photosynthetic rate were studied in Bougainvillea spectabilis ‘Killie Campbell’ plants, under interior conditions. The relationships between bract longevity and the above parameters were also investigated. NAA ...

Slips are side-shoots or fruit with large crowns that grow from buds on the pineapple ( Ananas comosus L.) peduncle. The slips widely used for vegetative propagation when left attached to is marketed. There a difference between two most popular low-acid hybrids grown worldwide. ‘Pineapple Research Institute 73-50’ (CO-2, MD-1) develop few roots planted compared 73-114’ (MD2). slow rooting of 73...

Onosma anatolica Binzet, is described and illustrated as a new species from Niğde province in southern Anatolia, Turkey. It belongs to sect. Onosma L. subsect. Asterotricha (Boiss.) Gürke. The new species is closely related to Onosma subulifolia Riedl from which it is distinguished. Onosma anatolica is readily distinguished from Onosma subulifolia by its sterile shoots, the green-grey stem indu...

A new genus of Compositae, Shangwua, is described to accomodate all species formerly placed in Saussurea sect. Jacea. This genus is distinct from the other genera of tribe Cardueae in its unique combination of states of characters including involucral bracts, receptacle, paleae, anther, style, achene and pappus. Phylogenetic analyses based on molecular data suggest that this new genus belongs t...
