Tulipa akamasica (Ldiaceae) is described as new to science. Its occurrence is restricted to a small area on serpentine substrate in the Akamas peninsula in the western part of Cyprus. The diploid plant belongs to the controversial T orphanidea species group, but differs from its segregates by the delicateness of most organs.

A leaf spotting disease of an ornamental variety of Ophiopogon japonicus was discovered at several locations in northern Thailand. In all cases a species of Phyllosticta was associated with the lesions. Phyllosticta ophiopogonis sp. nov. is distinguished from Phyllosticta species from Liliaceae in conidia size, mucilaginous sheath and appendage thus the species is introduced as new in this paper. The new species which causes unsightly lesions on this ornamental plant is described, illustrated and compared with other similar Phyllosticta species.

In this study, pollen grains and anatomical features of Turkish lilies were investigated under the electron (SEM) and light (LM) microscope. LM and SEM observations showed that the pollen grains are monosulcate, heteropolar, elliptical in polar view and oblate. Numerical results based on combined palynological and anatomical characters were discussed and compared with traditional taxonomic treatments. It was found that the midrib shape, mesophyll type, P/E (polar/equatorial), sulcus length, and lumina width are the most valuable traits in separating the examined taxa. The numerical analysis showed that Lilium candidum L. differs from the rest Turkish Lilium and also confirmed a close relationship between L. szovitsianum Fisch. & Av,-Lall. and L. armenum Miscz. ex Grossh. Also this study is the first report dealing with anatomical and palynological features of all Turkish lilies.

This study aims to determine the age of individual plants of the perennial herb Lilium polyphyllum in its natural habitats. Plant age was successfully estimated as the number of years a seed takes to produce the first stem plus the number of remnants of old shoots visible on the basal plates of the bulbs. Plant age as well as morphological features of shoots and bulbs were recorded at one temperate and one high altitude site. There were significant differences between the sites with respect to plant height, leaf number, bulb diameter and weight. The results show that individuals of similar age differ in morphology between temperate and high altitude sites. At both sites, all flowering plants of L. polyphyllum were 10–12 years old.

To resolve the current taxonomic status of Japanese endemic Fritillaria L., their taxonomic history is retraced. All taxonomic papers are evaluated, together with more recent genetic observations. To determine the wider acceptance of various taxonomic revisions, a range of Floras are also examined. It is evident that articles published in Japanese have not been fully considered by the wider botanical community. Moreover, rivalries between the Tokyo and Kyoto schools of botany and an over-reliance on herbarium material by many authors have undermined the current classification of the Fritillaria `japonica group'.
