In the strictest terms, a double ower is one in which the sex organs (anthers and pistils) are transformed into petal- like structures; such owers are thus sterile. This use possibly accounts for an erroneous statement by Barwick (2004) with reference to the mutant, that ‘this double- owered form lacks a functional pistil and does not produce fruit.’ The owers produce both pistils and anthers. The pistil matures earlier than the anthers; the style elongates and exposes the stigma before the bud opens. This facilitates cross fertilization. The mutant form of W. coccinea (‘double’ Chaconier) Fruit and seed are formed normally. Seed germination is easily accomplished, but seedling establishment is problematic.

If you saw it creeping along the driveway at Asa Wright, you might mistake it for an earthworm. It is about the same size, has the same pinkish hue, and prefers moist and dark places. But look closer and you will see some important di erences. The velvet worm has two long feelers with which it probes the ground in front of it. It moves, not by slithering, but by walking on stubby, caterpillar-like legs. Examine its head and you will nd two nozzles on either side of its mouth.

Lately he has ventured into understanding the life cycle of the butter y, with a particular interest in the Monarch butter y species as his garden has been experiencing a large in ux of these butter les since the beginning of 2018. His rearing of Milkweed plants attracted this rather unexpected number of beautiful pollinators to his garden and no sooner, the photographer’s eye was captivated and a new interest was sparked. Coming out of his own research, he which he nurtured from caterpillar to has heeded a recent international call adult stage during the Easter school by environmentalists and butter y vacation, for several days, revisited conservationists for the incubation regularly and followed Raimundo and nurturing of the Monarch butter y about the garden.

(Rubiaceae) but with conflicting circumscriptions. In the present study, phylogenetic analyses based on nrITS and trnT-F sequence data of 78 taxa are performed to evaluate the dif- ferent circumscriptions of Sabiceeae, the generic limits within Sabiceeae, and the biogeography of Sabicea. The polyphyly of Sabiceeae sensu Andersson is confirmed, and Pentaloncha and Temnopteryx are shown not to belong to Ixoroideae s.l. but to the subfamily Rubioideae. Our results favour a broad circumscription of Sabiceeae that includes Ecpoma, Hekistocarpa, Pseudosabicea, Sabicea, Schizostigma, Stipularia, Tamridaea and Virectaria.

They are also characteristic of the identities of different ethnographic groups in tropical America. However, information regarding the botanical characterization of chacras is scant. In tropical rural communities, there is a gender bias hypothesis that makes women potential reservoirs of traditional chacras plant knowledge. We present an experimental study in order to demonstrate if this knowledge difference really exists and to plan accordingly. We performed workshops in an isolated Kichwa community from Amazonian Ecuador. We calculated the cultural signififcance index (CSI) for 97 local flora plants. Our results revealed statistically significant differences. They were coherent with the Kichwa worldview and the structure of their society. We concluded that gender perspective must be taken into account in biodiversity conservation programs, such as, for example, those to implement the resilient agricultural practices of tropical contexts promoted by The United Nations Sustainable Development Goal 2 (SGD2).

Walking forested areas, along roads and paths, we try to convey the diversity of the flora of the Eastern Andes of Ecuador. Our exploration progresses through the main vegetation formations of a corridor traced between Quito and Vilcabamba, with side trips to the Cloud Forest on the eastern slopes. During the trip, we had brief evening gatherings to identify some of the readily described flowers up to level of genus. We photographed flowers belonging to 184 genera and 74 families. Among them, I identified 220 flowers to the species level. These 220 species included 34 plants endemic to Ecuador, 55 specialties unique to Ecuador and either Colombia or Peru, and 16 species only available in the territory covered by the three countries. In the end, our 14 day adventure generated a list of 105 range restricted flowering plants identified to species, which can be seen only in the Andes of either Ecuador or its neighbouring countries. Most of them occurr in habitats which also represent a reduced extension of native vegetation, for example: the Andean Paramos and the Dry Inter-Andean Valleys.

  • A SURVEY of the SYSTEMATIC WOOD ANATOMY of the RUBIACEAE by Steven Jansen1, Elmar Robbrecht2, Hans Beeckman3 & Erik Smets1
    IAWA Journal, Vol. 23 (1), 2002: 1–67 A SURVEY OF THE SYSTEMATIC WOOD ANATOMY OF THE RUBIACEAE by Steven Jansen1, Elmar Robbrecht2, Hans Beeckman3 & Erik Smets1 SUMMARY Recent insight in the phylogeny of the Rubiaceae, mainly based on macromolecular data, agrees better with wood anatomical diversity patterns than previous subdivisions of the family. The two main types of secondary xylem that occur in Rubiaceae show general consistency in their distribution within clades. Wood anatomical characters, espe- cially the fibre type and axial parenchyma distribution, have indeed good taxonomic value in the family. Nevertheless, the application of wood anatomical data in Rubiaceae is more useful in confirming or negating already proposed relationships rather than postulating new affinities for problematic taxa. The wood characterised by fibre-tracheids (type I) is most common, while type II with septate libriform fibres is restricted to some tribes in all three subfamilies. Mineral inclusions in wood also provide valuable information with respect to systematic re- lationships. Key words: Rubiaceae, systematic wood anatomy, classification, phylo- geny, mineral inclusions INTRODUCTION The systematic wood anatomy of the Rubiaceae has recently been investigated by us and has already resulted in contributions on several subgroups of the family (Jansen et al. 1996, 1997a, b, 1999, 2001; Lens et al. 2000). The present contribution aims to extend the wood anatomical observations to the entire family, surveying the second- ary xylem of all woody tribes on the basis of literature data and original observations. Although Koek-Noorman contributed a series of wood anatomical studies to the Rubiaceae in the 1970ʼs, there are two principal reasons to present a new and com- prehensive overview on the wood anatomical variation.
