Pirton Village Hall, High Street, Pirton, near Hitchin, SG5 3PS 2 Acanthocalycium violaceum (Lobivia spiniflora) by John Grourk Acanthocalycium violaceum can grow to be some 60cm tall and 15cm in diameter. This means mine is still a ‘baby’ at only 8.5cm tall and 10cm in diameter. It is growing up rapidly though, having got some 2cm taller and added another 2cm in diameter over the past year. I have had the plant for about two years and it flowered for the first time in 2013 with a flush of six flowers in June, followed by two more in August. Then, in September 2013, it produced a further 13 flowers, shown here. Unfortunately, as with most plants in this group, the flowers only lasted for about three days. After this, the flowers resembled a candle-like shape with the violet colour remaining for some time. A violaceum will not normally flower until it is at least four years old, and it must have bright sunlight to encourage flowering. The blooms will close up when the sun goes in, and also at night. Although my plant was kept in a bright conservatory I still placed it outside in full sun whenever possible. During the summer period I watered roughly every three weeks and added a high potassium feed on three occasions. I do not water from October onwards, and give a cool period during the winter to encourage flowering next year. I What's in a name? In 'The New Cactus Lexicon' 2006 Acanthocalycium violaceum became Echinopsis spiniflora. In 'The New Cactus Lexicon Illustrations' 2013, the genus Lobivia is reinstated (minus some of its previous members) and so E spiniflora became Lobivia spiniflora. Editor Do you have a plant of which you are particularly proud? Perhaps it flowered for the first time this year, or has done exceptionally well. If so I would like to feature it in the Essex Succulent Review. Please let me have some details, together Above: A violaceum in John’s collection, and with pictures (contact details on page 2).

The young plants are globular, then columnar up to 1m tall, 12 cm diameter and about 30 ribs. Old plants cluster from the base. Flowers are yellow, 5 cm diameter, at the top of the plants, but only if adult (at least 20 cm tall) It produces very attractive, yellow, silky textured, funnel-shaped flowers in summer and is very popular even though it will take around five years to produce its first flowers. They start off having a spherical shape but become more columnar as they age and will naturally cluster from the base. Good for xeriscape and gravel gardens but perhaps best suited to growing in containers where they can be brought indoors in winter.

  • Variación En La Anatomía De La Madera De Pachycereus Pecten-Aboriginum (Cactaceae)
    Anales del Instituto de Biología, Universidad Nacional Autónoma de México, Serie Botánica 72(2): 157-169. 2001 Variación en la anatomía de la madera de Pachycereus pecten-aboriginum (Cactaceae) SALVADOR ARIAS* TERESA TERRAZAS** Resumen. Se estudiaron 17 muestras de Pachycereus pecten-aboriginum procedentes del occidente de México con el objetivo de describir la madera y evaluar su variación con relación a la latitud, altitud y altura del individuo. Se encontró que la madera de P. pecten-aboriginum corresponde a una madera fibrosa mesomórfica típica de la subfamilia Cactoideae. La longitud de la fibra, el número y diámetro de los vasos tuvieron una asociación significativa con la latitud, mientras que la altura de los radios se correlacionó con la altura del individuo significativamente. La altura del individuo no mostró correlación con los elementos traqueales (fibras y elementos de vaso). La variación anatómica de algunos caracteres de la madera de P. pecten-aboriginum evaluados confirman el comportamiento registrado para otras especies de amplia distribución geográfica. Palabras clave: madera, variación latitudinal, Pachycereus, Cactaceae. Abstract. Seventeen samples of Pachycereus pecten-aboriginum wood from western Mexico were studied with the main purpose to describe its wood and to evaluate its variation in relation to latitude, altitude and tree height. We found that P. pecten-aboriginum has the typical fibrous and mesomorphic wood of Cactoideae subfamily. Fiber length, vessel number and diameter correlated significantly to latitude, whereas ray height showed a significant correlation with altitude. However, tree height did not show any correlation with tracheary elements (fibers and vessel elements). Moreover, some of the anatomical characters of P.

Chloroplast DNA sequences of the trnK intron, including the matK gene, were sequenced for 70 ingroup taxa and two outgroups from the Portulacaceae. In order to improve resolution in three major groups of Cactoideae, trnL-trnF sequences from members of these clades were added to a combined analysis. The three exemplars of Pereskia did not form a monophyletic group but a basal grade. The well-supported subfamilies Cactoideae and Opuntioideae and the genus Maihuenia formed a weakly supported clade sister to Pereskia. The parsimony analysis supported a sister group relationship of Maihuenia and Opuntioideae, although the likelihood analysis did not. Blossfeldia, a monotypic genus of morphologically modi®ed and ecologically specialized cacti, was identi®ed as the sister group to all other Cactoideae.

  • ON the TAXONOMY of CACTACEAE JUSS by the EVIDENCE of SEED MICROMORPHOLOGY and SDS-PAGE ANALYSIS Lamiaa F
    European Journal of Botany, Plant Sciences and Phytology Vol.2, No.3, pp.1-15, October 2015 ___Published by European Centre for Research Training and Development UK (www.eajournals.org) ON THE TAXONOMY OF CACTACEAE JUSS BY THE EVIDENCE OF SEED MICROMORPHOLOGY AND SDS-PAGE ANALYSIS Lamiaa F. Shalabi Department of Biological and Geological Sciences, Faculty of Education, Ain Shams University, Cairo, Egypt. Biology Department, Faculty of Sciences, Jazan University, Jazan, Saudi Arabia. ABSTRACT Numerical classification of 16 taxa of Cactaceae was studied using combination of micromorphological characters of seeds (using L.M and SEM) and SDS- PAGE analysis. Aspects of seed micromorphology and seed protein variation as defined were recorded and scored comparatively for the OTU's into a data matrix. Phenetic relationships of these taxa were established based on UPGMA-clustering method by using Jaccard coefficient of the NTSYS-pc 2.2 program. The results were compatible with the traditional relationships of some taxa as the split-off of Opuntia humifusa and Astrophytum myriostigma, at separate lines, these results are compatible with their placement in tribes Opuntieae (subfamily Opuntioideae) and Cacteae (Subfamily cactoideae) respectively, at the time, the placement of three taxa Pseudorhipsalis ramulosa, Rhipsalis baccifera Accession 1, and Rhipsalis baccifera Accession 2 together, the clustering of Hylocereus triangularis and Neobuxbaumia euphorbioides together at a unique tribe Phyllocacteae. The findings contradict in a number of cases the traditional studies, as the grouping of Trichocereus vasquezii with the two represents of genus Parodia despite of their placement in different tribes. KEYWORDS: Cactaceae, SDS-PAGE, Seed micromorpgology, SEM INTRODUCTION The Cactaceae are an exciting and problematic group of plants because of their varied morphology, succulence, and their showy flowers (Barthlott and Hunt 1993).
