亞科



  • 莧亞科 Amaranthoideae


  • 甜菜亞科 Betoideae


  • 藜亞科 Chenopodioideae


  • 千日紅亞科 Gomphrenoideae


  • 鹽角草亞科 Salicornioideae


  • 豬毛菜亞科 Salsoloideae




莧科[註 1]（学名：Amaranthaceae）包括160属大约2,400种植物，多为草本或灌木，稀有乔木或藤本[1][2]。


莧科广泛分布在全世界，一般分布在亚热带和热带地区，但也有许多种也分布在温带甚至寒温带地区[1][2]。


2003年的APG II 分类法将藜科合并到苋科中来，两者的唯一区别是苋科花被膜质，藜科附着粉状或皮屑状物；苋科蒴果，藜科胞果[1][2]。


不包括藜科的苋科仅有65属大约900种，大部分生活在热带非洲和北美洲，许多品种可以在盐碱地生长，有的品种是杂草，也有花卉品种。如鸡冠花、千日红和老来少等[1][2]。


苋科植物单叶对生或互生，叶缘有齿，大部分无托叶。

Run scheduled task as local user group (not BUILTIN)

Image
0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
