Diestostemma Amyot & Serville, 1843 is a diverse sharpshooter genus with 32 species. A description and illustrations of Diestostemma nasutum Schmidt, 1910 are provided. The species, previously known from Ecuador, is newly recorded from Colombia. Both the male and female genitalia are described for the first time. This is the first detailed description of the female genitalia of a Diestostemma species. Diestostemma nasutum can be distinguished from the other species of the genus by the following features of the aedeagus: shaft with the distal third distinctly curved dorsally; base of basiventral aedeagal process with a lobe directed anteriorly; and basiventral aedeagal process bifurcated on its basal portion. The style of D. nasutum, whose apical portion is broad, distinctly curved inward, and with the apex subtruncate, is also quite distinctive. We compared the female genitalia of D. nasutum with those of other Proconiini genera. Our results confirm the perception that the female genitalia in this tribe can be a source of useful taxonomic characters.

Quintais são espaços de fácil acesso e cômodos para os moradores cultivarem uma diversidade de espécies que desempenham funções de estética, lazer, alimentação e medicinal, dentre outras. O objetivo deste trabalho foi o de descrever a composição florística e a respectiva utilização em quintais urbanos de Mirassol D'Oeste, MT, (15º 45'30"S e 058º16'36"W), com a coleta de dados envolvendo: entrevistas estruturadas e semi-estruturadas aplicadas a 29 moradores; coleta simultânea do material botânico das espécies indicadas, incorporação destas no Laboratório de Botânica da UNEMAT, Cáceres e análise da freqüência absoluta e relativa das espécies mais citadas e encontradas nos quintais. Foram registradas 397 denominações locais de plantas (etnoespécies), 275 taxa reunidos em 79 famílias destacando-se com maior número de espécies: Solanaceae (23), Asteraceae (17), Lamiaceae (14), Rosaceae (12) e Verbenaceae (9). Os atributos alimentar e ornamental representam, individualmente, 35% das espécies e o medicinal, 29%. Algumas plantas detêm até quatro potencialidades. Do universo vegetal conhecido e utilizado localmente as espécies nativas correspondem a 8%, resultado considerado baixo comparando-se aos obtidos em populações mato-grossenses radicadas no Cerrado e Pantanal. Essa população manifesta por meio de suas práticas uma tradição agrícola em interface às características de uma sociedade urbano - industrial coabitando em espaços comuns, o quintal.

A home garden is a small track of ground next to or surrounding a house where its residents can cultivate a diversity of plants, whose function is aesthetic, leisure, food, medicinal among others. The aim of this work was to study the floristic composition of urban homegardens in the city of Mirassol D'Oeste, state of Mato Grosso, coordinate 15º45'30"S and 58º16'36"W. For colleting data we interviewed 29 residents using structured and semi-structured interviews; and, simultaneously collected botanical species which we analysed at the Mato Grosso State University Botanical Laboratory, in Cáceres. We made statistical analyses using absolute frequency and relative frequency to quantify and specify the botanical species found in the gardens. We registered a total of 397 ethnobotanical species and grouped 275 taxa in 79 botanical families. The highest numbers among them were 23 species of Solanaceae, 17 Asteraceae, 14 Lamiaceae , 12 Rosaceae and 9 species of Verbenaceae. Food and ornamental attributes represented 35 % of the species and medicinal 29% . Some species had up to four potentialities. From the known plant universe used locally, native species corresponded to 8%. This percentage was considered low when compared to that of the population living in the Pantanal and cerrado areas. This population demonstrated an interface between agricultural tradition and the characteristics of urban-industrial society living in common spaces: the homegardens.
