学名

Crepidiastrum lanceolatum (Houttuyn) Nakai

ホソバワダン（細葉海菜、Crepidiastrum lanceolatum）は、キク科の多年草である。近縁種のワダン C. platyphyllum より葉が細いことから命名された。


分布は島根県・山口県の日本海側から沖縄、朝鮮半島南部・中国の海岸の岩場から山裾にかけて生育する。高さ約20～30cmで、地表面にロゼット状の葉を広げ、長さは20〜30cmに達する。長楕円形のものと羽状に深裂した葉の2形がある。基部から多くの茎を出し、太く木化する。
花は10〜11月に、黄色の舌状花を約12個もつ頭花を散状に開く。2〜3.5cmほどの痩果になる（冠毛は3〜5mm）。


近縁種のアゼトウナ C. keiskeanum に酷似しているが、ホソバワダンは葉が茎の基部を抱くことから区別できる。


強い苦味を持ち、沖縄県では、葉をニガナ（ンジャナ）の名で食用としている（日本に自生するニガナ Ixeris dentata は別種）。

How to fix TextFormField cause rebuild widget in Flutter

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box; } 0 I've got the same issue at #9280. I tried all solutions from that topic with/without GlobalKey for Scaffold and Form but the problem wasn't fixed. I tried to build a authentication form with login and signup. But the keyboard doesn't show when I tap the TextFormField at the first time. Then I try to input some letter from physical keyboard, the widget is rebuilt. Like this: login screen Nothing to be log when I run flutter run --verbose, so I logged manually. Every tapping on field, the widget called dispose -> init -> build.

in spring boot 2.1 many test slices are not allowed anymore due to multiple @BootstrapWith

Image
1 I tried to upgrade a yummy sandwich made of two test slices (@JsonTest and @JdbcTest in my case, crunchy test code in between) adding spring boot 2.1 flavour to it. But it seems it was not much of a success. I cannot annotate my tests with many @...Test since they are now each bringing their own XxxTestContextBootstrapper. It used to work when they all used same SpringBootTestContextBootstrapper. @RunWith(SpringRunner.class) @JdbcTest @JsonTest public class Test { @Test public void test() { System.out.printn("Hello, World !"); } } The error I get from BootstrapUtils is illegalStateException : Configuration error: found multiple declarations of @BootstrapWith for test class I understand I might be doing something wrong here but is there an easy way I could load both Json and Jdbc contex...
