Description
Appearance and leaves
Burchardia species grow as perennial herbaceous plants. These geophytes form as storage organs underground tubers of which are covered with parchment -like scales. The roots may be bulbous. The aboveground plant parts are bare. The upright stems are leafy.
There are usually one to five undergraduate, rarely alternate, spirally arranged on the stem or two lines, sedentary leaves available, which are divided into leaf sheath and blade. The simple leaf blade is folded, linear or lance-shaped and parallel-veined.
Inflorescences and flowers
The inflorescence stem is simple or has one to four branches. One to four bracts are under the inflorescence. The flowers are rarely individually or mostly up to twenty together in terminal, doldigen inflorescences. There are flower stems available. Bracts absent.
The hermaphrodite flowers are radial symmetry and threefold. The six equal multiform bracts are free. The color of the bloom depending on the type or green to greenish white to pink. Near the base of the bloom nectaries are usually present. There are two circles, each with three fertile stamens present. The inserted at the base of the bloom, with each free stamens are short and somewhat flat. The dorsifixen, motile anthers are bent outward and open with longitudinal slots. Three carpels are fused to a constant above, dreikammerigen ovary. Each ovary chamber contains a central angle constant placentation some ovules. The short style splits into three branches, stylus.
Fruit and seeds
The septizidalen capsule fruits contain some seeds. The wrinkled seeds contain oil-containing endosperm and designed with a Phytomelane brown seed coat ( testa). The straight embryo has one cotyledon ( cotyledon )
Systematics and distribution
Five of the six Burchardia species occur only in Western Australia and is widely used in all Australian states except the Northern Territory and Western Australia.
The genus Burchardia was erected in 1810 by Robert Brown in Prodromus Novae Florae Hollandiae, p 272. Type species is Burchardia umbellata R.Br.. Burchardia The genus name honors the German botanist Johann Heinrich Burckhardt ( 1676-1738 ). Synonyms for Burchardia R.Br. are Reya Kuntze and Burckhardia T.Post & Kuntze orth var. Burchardia R.Br. is in accordance with ICBN rules ( Vienna ICBN Art 14 & App. III) conserved ( nom. cons. ) compared to the Parahomonym ( Vienna ICBN Art 53.3 ) Burcardia Heist. ex Duhamel 1755 nom. rej .. Another homonym is Burchardia Neck. published in Noel Martin Joseph de Necker: Elementa botanica ...., 2, 1790, pp. 76 and genus within the Myrtaceae.
Burchardia is the only genus of the tribe Burchardieae JCManning & Vinn. within the family Colchicaceae DC.; it was formerly classified in the family Burchardiaceae Takht. , Liliaceae and Uvulariaceae. The tribe was Burchardieae by Annika Vinnersten and John C. Manning in A new classification of Colchicaceae In: erected taxon, Volume 56, Issue 1, 2007, pp. 163-169.
There are about six Burchardia types:
- Burchardia bairdiae Keighery: It occurs in Western Australia.
- Burchardia congesta Lindl. It occurs in Western Australia.
- Burchardia monantha Domin: It occurs in Western Australia.
- Burchardia multiflora Lindl. It occurs in Western Australia.
- Burchardia rosea Keighery: It occurs in Western Australia.
- Burchardia umbellata R.Br.: It comes in all states before except the Northern Territory and Western Australia.
Use
From Burchardia umbellata the underground plant parts are eaten raw or cooked. The taste is unclassifiable. It is similar to a lot of strength as in raw potatoes contain.
