Description

Eriophyllum is an annual or perennial shrub or subshrub, some species growing to a height of 200 cm (6.7 feet). Leaves present generally alternate and entire to nearly compound, with woolly hairs on some of the species. The inflorescence contains numerous yellow flower heads in flat-topped clusters. The involucre structure is obconic to hemispheric. Phyllaries are either free or more or less fused; the receptacle presents typically flat, but naked. The ray flowers are present in some species but not in others. Fruits are angled in the outer flowers, but are generally club-shaped for the inner flowers; the pappus is somewhat jagged.[6][7]

Selected species
gollark: Oh, minoteaur actually has that (not the threading bit) in its Markdown parsing code.
gollark: Thus, praise ~~Rust~~ ~~Ferris~~ Nim?
gollark: It compiles in reasonable time *and* makes a 600KB binary in debug mode which is much nicer than equivalent Rust.
gollark: I only need something like two routes so a full web framework is overkill.
gollark: ```nimimport optionsimport asyncdispatchimport httpximport tiny_sqliteimport macrosimport karax/[karaxdsl, vdom]import ./dbmacro includeFile(x: string): string = newStrLitNode(readFile(x.strVal))const css = includeFile("./src/style.css")let database = openDatabase("./monitoring.sqlite3")migrate(database)var threadDB {.threadvar.}: Option[DbConn]proc openDB(): DbConn = if isNone threadDB: threadDB = some openDatabase("./monitoring.sqlite3") get threadDBproc mainPage(): string = let vnode = buildHtml(html()): head: style: text css text "Bee deployed" $vnodeproc onRequest(req: Request) {.async.} = if req.httpMethod == some(HttpGet): case req.path.get() of "/": req.send(body=mainPage(), code=Http200, headers="Content-Type: text/html") else: req.send(Http404) else: req.send(Http404)echo "Starting up"run(onRequest, initSettings(Port(7800), "", 0))```This is what I have so far.
