Diversity and use of trees and shrubs in smallholder farming • Accepted: 27/Oct/2020 systems in the Colombian Andes. Caldasia 43(1):49–64. doi: https://dx.doi.org/10.15446/caldasia.v43n1.84230. • Online Publishing: 9/Nov/2020 ABSTRACT This article describes the diversity and use of trees and shrubs in smallholder farming systems in three municipalities of the department of Boyacá in the Colombian Andes, and tests the relations between spe- cies richness, use, and a set of socio-economic and structural variables. We conducted ethnobotanical walks and semi-structured interviews on 24 farms to characterize all tree and shrub species. In total, we recorded 142 species with a predominance of natives (88) versus exotics (54). Species richness ranged between four and 40 (X = 25.17; SD = 10.13) per farm and was homogeneous among the municipalities (P > 0.05, Kruskal-Wallis test). We recorded 52 wild species, eight of them endemic, all representative of the surrounding native flora, of which 23 % had some type of use. Cultivated species were mostly represented by exotics that had been planted primarily as live fences, ornamentals, or edibles.

  • Observations on the Distribution and Ecology of Sida Hermaphrodita (1.) Rusby (Malvaceae)
    OBSERVATIONS ON THE DISTRIBUTION AND ECOLOGY OF SIDA HERMAPHRODITA (1.) RUSBY (MALVACEAE) DAVID M. SPOONER Departmentof Botany, The OhioState University Columbus, OH 43210, U.S.A. ALLISON W. CUSICK Ohio Dept. of Natural Resources,Division of Natural Areas & Preserves Columbus, OH 43224, U.S.A. GEORGE F. HALL Departmentof Agronomy,The Ohio State University Columbus, OH 43210, U.S.A. JERRY M. BASKIN School of Biological Sciences, University of Kentucky Lexington, KY 40506, U.S.A. ABSTRACT Sida hermaphrodita (L.) Rusby (Malvaceae) is a perennial herb of riverine habitats in the northeastern and midwestern United States that presently is under consideration for listing as a federally endangered or threatened species. Although the species is rare in most sections of its range, it is locally common in a limited area along the Kanawha and Ohio rivers in West Virginia and Ohio. In contrast to previous reports, evidence is presented that Sida hermaphrodita is indigenous to the Great Lakes drainage. Its disttibution and abundance is not limited either by soil type or by low seed viability or germination potencial. Gametophytic and sporophytic chromosome numbers are 14 and 28, respectively. Al- though Sida hermaphrodita is not immediately in danger of extinction, its habitat continues to be severely altered by man, and no populations of this species presently are protected from destruction. INTRODUCTION Sida hermaphrodita (1.) Rusby (Malvaceae) (Virginia mallow, River mallow) is a polycarpic perennial herb of open, moist, sunny to partly shad- ed riverine habitats. The species is the only member of Pseudonapaea A. Gray, a section without close affinity to any other section in the genus (Clement 1957; Fryxell 1985).

ABSTRACT During past several years, there has been growing interest among the usage of various medicinal plants from traditional system of medicine for the treatment of different ailments. A number of herbs belonging to the specie Abutilon are noted for their medicinal benefits in traditional system of medicine. A lot of medicinally important attributes have been assigned to the plants of this specie. The important plants of this specie which have been so far explored include A. indicum, A. theophrashti, A. grandiflorum and A. muticum etc. Also, large number of reports on Abutilon spp. indicates continuous scientific research on it with special reference to their medicinal cultivation and biotechnological applications. In light of this, the present review aims at exploring current scientific findings on the various plants of this specie. Keywords: Abutilon, scientific findings, traditional system of medicine. *Corresponding author Email: [email protected] October – December 2010 RJPBCS 1(4) Page No. 718 ISSN: 0975-8585 INTRODUCTION The Abutilon L. genus of the Malvaceae family comprises about 150 annual or perennial herbs, shrubs or even small trees widely distributed in the tropical and subtropical countries of America, Africa, Asia and Australia [1]. Various plants of Abutilon species are traditionally claimed for their varied pharmacological and medicinal activities. Furthermore, different plant parts contain specific phytoconstituent responsible for their biological activity.

Throughout most of its geographical distribution however, it is considered threatened and only two populations are known from Canada. The biology and ecology of S. hermaphrodita are still poorly understood and although few studies have been performed to determine the factors that contribute to the species rarity, it is considered threatened potentially due to the loss of habitat caused by exotic European Common reed (Phragmites australis subsp.
