A New Species

Habenaria luquanensis from Yunnan Province is described and illustrated. This new species most closely resembles H. delavayi in having a basal leaf rosette, flowers with a concave and abaxially keeled dorsal sepal and linear petals. It is distinguished by herbaceous, loosely arranged rosette leaves (versus tightly adpressed to each other), a lip which is 3-lobed only to 1/3–1/4 from the base and has narrowly oblong lateral lobes (versus deeply 3-lobed nearly to the base with linear-cuneate lateral lobes). Another similar species is H. finetiana, but this species can be distinguished by its cauline leaves, longer floral bracts, petals forming a hood with the dorsal sepal, a lip which is 3-lobed only in the upper half and  rhombic, serrate lateral lobes, a spur which is nearly as long as the ovary, and central rostellum lobe not clearly visible.

<p><em>Salvia multicaulis</em> is a widespread species of Lamiaceae family in Iran. There are many discussions about its infraspecific variations. Although some varieties were definite for this species in various parts of the world, no infraspecific taxon was reported in Iran and all samples of this species were named as S. multicaulis. In this study, morphological characteristics of S. multicaulis populations, naturally growing in Iran, was examined. Twenty-two traits were examined in 94 individuals of this species to<br />identify their phenotypic difference. Most of the investigated features were showing a high degree of variability, but it was highly pronounced for some characteristics such as basal leaf shape, basal leaf width, basal leaf length/ width ratio and basal petiole length. Significant positive/negative correlations were observed between some morphological variables. Furthermore, significant negative correlations were found between the eastern distribution of populations with basal leaf petiole length and basal leaf length/ width ratio. Based on the UPGMA cluster analysis, populations were divided into two main branches. The first branch contained four populations, while the second branch was bigger and clustered in two sub-branches. In one of them,<br />three populations and in another one the rest populations arranged in two groups. CA joined plot confirmed that each of studied populations or group of populations had distinct morphological trait(s), which were useful in identification of them. Our findings supported population no. 13 had unique morphological traits such as the largest bracts and basal leaf petiole, highest flower number of each inflorescence cycle, widest and largest calyx. The conservation of the highly diverse populations of<br />Iranian S. multicaulis is recommended.</p>

African Genus

Following field and herbarium investigation of the subequatorial African and mainly western southern African Ferraria Burm. ex Mill. (Iridaceae: Iridoideae), a genus of cormous geophytes, we recognize 18 species, eight more than were included in the 1979 account of the genus by M.P. de Vos. One of these, F. ovata, based on Moraea ovata Thunb. (1800), was only discovered to be a species of Ferraria in 2001, and three more are the result of our different view of De Vos’s taxonomy. In tropical Africa, F. glutinosa is recircumscribed to include only mid- to late summer-flowering plants, usually with a single basal leaf and with purple to brown flowers often marked with yellow. A second summer-flowering species, F. candelabrum, includes taller plants with several basal leaves. Spring and early summer-flowering plants lacking foliage leaves and with yellow flowers from central Africa are referred to F. spithamea or F. welwitschii respectively.

African Genus

We describe eight new southern African species in the largely sub-Saharan African genus Moraea L., one from the winterdry Great Karoo and the others from the winter-rainfall zone of the southwest of the subcontinent. M. striata Goldblatt J.C.Manning (subg. Visciramosae Goldblatt) from the southern foothills of the Great Swartberg Mtns has khaki-green flowers with reflexed tepal limbs streaked with dark lines. The acaulescent M. singularis Goldblatt J.C.Manning (subg. Umbellatae Goldblatt J.C.Manning) with terete leaf blades is restricted to the dry, interior foothills of the Kamiesberg in Northern Cape. M. filamentosa Goldblatt J.C.Manning, subg. Acaules (Baker) Goldblatt J.C.Manning, is described from the dry interior of Namaqualand in Northern Cape. The species is closely allied to the widespread M. falcifolia Klatt. In subg. Polyanthes (Goldblatt) Goldblatt J.C.Manning, we describe M. thermarum Goldblatt J.C.Manning (sect. Hexaglottis (Vent.) Goldblatt) from southwestern Namibia, allied to M. brevituba (Goldblatt) Goldblatt, and M. lazulina Goldblatt J.C.Manning (sect. Pseudospicata Goldblatt J.C.Manning) from the Little Karoo, until now confused with M. exiliflora Goldblatt but differing in its larger flowers with strongly reflexed tepals. The new M. petricola Goldblatt J.C.Manning (subg. Vieusseuxia (D.Delaroche) Goldblatt), is restricted to higher elevations of the Pakhuis Mtns of northern Western Cape. Lastly, in subg. Homeria (Vent.) Goldblatt J.C.Manning, we recognize M. doleritica Goldblatt J.C.Manning with pale yellow flowers and anthers exceeding the style branches, restricted to dolerite outcrops in the Great Karoo, and M. eburnea Goldblatt J.C.Manning from the northern foothills of the Klein Swartberg, which has a single, basal leaf and pale yellow flowers with filaments free distally. Moraea now has 222 species, including 203 in southern Africa, of which 200 are endemic to the region. In addition to describing new species, the paper brings to light range extensions of a further eight species: M. barnardii L.Bolus, M. elliotii Baker, M. exiliflora Goldblatt, M. falcifolia Goldblatt J.C.Manning, M. fenestralis (Goldblatt E.G.H.Oliver) Goldblatt, M. louisabolusiae Goldblatt, M. tulbaghensis L.Bolus and M. unguiculata Ker Gawl. Each of the species falls into one of the subgenera mentioned for the new species except M. fenestralis which belongs in subg. Galaxia.

Canopy Management

Vigorous, Geneva Double Curtain-trained Okanagan Riesling vines were subjected over a 2-yr period (1987–1988) to four canopy manipulation practices: shoot positioning; shoot positioning plus postbloom hedging to 12 leaves per shoot; basal leaf removal; and an untreated control, in combination with the presence or absence of iprodione (Rovral 50WP) fungicide sprays. Shoot positioning and shoot positioning plus hedging reduced weight of cane prunings relative to control vines in 1988, but increased yield, cluster weight, and berries per cluster. Shoot positioning, shoot positioning plus hedging, and basal leaf removal reduced °Brix in 1988, but tended to reduce titratable acidity in both seasons. Shoot positioning plus hedging reduced pH in 1987, while shoot positioning and shoot positioning plus hedging reduced pH and potassium (K+) in 1988. Neither Rovral nor canopy manipulation appeared to have any significant impact on the percentage of bunch rot-affected clusters. Shoot positioning of Geneva Double Curtain-trained Okanagan Riesling is recommended as a method to reduce titratable acidity, pH and K+, hence improving potential winegrape quality.Key words: Vitis, grape, hedging, shoot positioning, leaf removal, canopy management

Shape And Size

Rheum telianum is described as a new species from Kayatepe village (south-eastern Anatolia, Turkey). It is morphologically related to the west-central Asiatic R. ribes and R. rhizostachyum from which can be easily distinguish by its stem surface (slightly verrucose), leaf number, shape, and size (usually 1-basal leaf or rarely with a small one at base, reniform-rotate, 6.5–100 × 4.5–56 cm), achene shape and size (cordate-triangular, 8–15 × 8–16 mm). The distribution, notes on ecology, and conservation status of the new species are also provided.

Main Distinguishing Feature

Crepis lacera is a diploid species (2n = 8), mostly occurring in Italy, with a disjunct population in Albania. The names C. lacera, C. latialis and C. lacera f. titani are here lectotypified, and their taxonomic value is discussed. For the latter name, based on morphological, biogeographical and karyological results, we propose here the subspecific rank (C. lacera subsp. titani stat. nov.). In addition, basal leaf morphology variation, the main distinguishing feature between the two subspecies, is discussed in the light of paedomorphosis, and a distribution map for both subspecies is presented.
