The two new species Pentzia somalensis , from areas of gypseous soil in northern Somalia, and P. arabica from the limestone plateau of Hadramaut in southern Yemen, are described and illustrated. P. somalensis is the only member of Anthemideae known from Somalia, and the occurrence of Pentzia on both sides of the Gulf of Aden in the Horn of Africa region represents a major extension of the distribution of the genus that is otherwise restricted to southern Africa except for two species in Morocco, Algeria and Tchad.  相似文献

The new species Polygala praetermissa , a dwarf perennial herb growing in stony places on limestone, and P. dasanensis , a shrublet apparently confined to gypsum, are described. Both species occur in the Cal Miskaat Range in north-eastern Somalia, but P. praetermissa has a wider distribution in northern Somalia.  相似文献

The new combinations K. nogalensis and K. lunulata are made, and the recently described K. isabellae from eastern Ethiopia is placed in synonymy of K. lunulata.  相似文献

The new species Vigna monantha ( V. subgen. Vigna sect. Catjang ) from coastal dunes of northern and central Somalia, and V. virescens ( V. subgen.

The following new species, all related to the Somali endemic Jatropha nogalensis in/. sect. Spinosa subsect. Spinosae , are described and illustrated: J. humifusa (coastal dunes of central Somalia), J. inaequispina (north-central Somalia, on limestone), and J. collina and J. spinosissima (both rocky ground in north-eastern Somalia). A hybrid between J. humifusa and the rather distantly related J. pelargoniifolia is reported.  相似文献

Background

For more than a decade, most parts of Somalia have not been under the control of any type of government. This “failure of state” is complete in the central and southern regions and most apparent in Mogadishu, which had been for a long period in the hands of warlords deploying their private militias in a battle for resources. In contrast, the northern part of Somalia has had relatively stable control under regional administrations, which are, however, not internationally recognized. The present study provides information about drug abuse among active security personnel and militia with an emphasis on regional differences in relation to the lack of central governmental control—to our knowledge the first account on this topic.

Methods and Findings

Trained local interviewers conducted a total of 8,723 interviews of armed personnel in seven convenience samples in different regions of Somalia; 587 (6.3%) respondents discontinued the interview and 12 (0.001%) were excluded for other reasons. We assessed basic sociodemographic information, self-reported khat use, and how respondents perceived the use of khat, cannabis (which includes both hashish and marijuana), psychoactive tablets (e.g., benzodiazepines), alcohol, solvents, and hemp seeds in their units. The cautious interpretation of our data suggest that sociodemographic characteristics and drug use among military personnel differ substantially between northern and southern/central Somalia. In total, 36.4% (99% confidence interval [CI] 19.3%–57.7%) of respondents reported khat use in the week before the interview, whereas in some regions of southern/central Somalia khat use, especially excessive use, was reported more frequently. Self-reported khat use differed substantially from the perceived use in units. According to the perception of respondents, the most frequent form of drug use is khat chewing (on average, 70.1% in previous week, 99% CI 63.6%–76.5%), followed by smoking cannabis (10.7%, 99% CI 0%–30.4%), ingesting psychoactive tablets (8.5%, 99% CI 0%–24.4%), drinking alcohol (5.3%, 99% CI 0%–13.8%), inhaling solvents (1.8%, 99% CI 0%–5.1%), and eating hemp seeds (0.6%, 99% CI 0%–2.0%). Perceived use of khat differs little between northern and southern Somalia, but perceived use of other drugs reaches alarmingly high levels in some regions of the south, especially related to smoking cannabis and using psychoactive tablets.

Conclusions

Our data suggest that drug use has quantitatively and qualitatively changed over the course of conflicts in southern Somalia, as current patterns are in contrast to traditional use. Although future studies using random sampling methods need to confirm our results, we hypothesize that drug-related problems of armed staff and other vulnerable groups in southern Somalia has reached proportions formerly unknown to the country, especially as we believe that any biases in our data would lead to an underestimation of actual drug use. We recommend that future disarmament, demobilization, and reintegration (DDR) programs need to be prepared to deal with significant drug-related problems in Somalia.  相似文献

The new species Cucumis hastatus (widespread in southern Somalia, in deciduous bushlands), C. pubituberculatus (central Somalia, on open coastal dunes), C. Jeffrey-anus (southwestern Somalia and eastern Ethiopia, on alluvial soils), and C. baladensis (south-central Somalia, on fixed dunes), are described and illustrated. C. figarei is shown to be illegitimate, the correct name for the species apparently being C. pustulatus.  相似文献
