Xerophyte

Central Spines

1-4(-6), one much longer (1-2,5cm ), spreading or turned downward.

Seeds

0,8-1 mm, bell-shaped broadest at the hilum, somewhat, tuberculate, shiny and black.

Description

Parodia concinna subs. agnetaeSN|3536]]SN|15619]] var. aureispina is small cactus species forming a flattened and much-ribbed sphere that could develop up to seven golden-yellow flowers simultaneously in early summer spring. It one of the several forms of the very variable Parodia concinnaSN|15619]]SN|3536]] which form a complex of related taxon. It distinguish for the dense thin yellowish spines and more closely set areoles. It is still unclear whether this variable complex is one or several species. There is so much variation in spination that most authors choose to lump them together until further studies are done.

Flowers

1-5 produced together at the apex, bright yellow, funnel-shaped, large, about 5 to 8 cm across. Outer perianth-segments narrow, acute, reddish, inner perianth-segments oblong, yellow almost transparent, except the reddish tips, acute. Stigma-lobes scarlet. Scales on the ovary hairy in their axils. Perianth-tube slender.

Blooming Season

It produces several flowers at a time from spring to early summer that  remain open for about three days.

Spines

10 to 12, spreading, setaceous, hair-like to bristle-like, some more or less curved to twisted, brown, partly whitish to yellowish often poorly differentiated as centrals and radials.

Ribs

about 16 to 20, with somewhat conspicuous chin-like tubercles between the areoles

Stem

Simple, broadly globular or somewhat depressed at apex, eventually longer in age, about 3-10 cm tall, and 4-10 cm across, light or dark glossy green, ribbed and warty at the top.

Radial Spines

9 to 25, about 5 to 7 mm or more long adpressed and interlaced.

Fruits

Green ovoid to globular approx. 1,5 cm cm long, thin-walled, splitting or disintegrating at maturity with more than 100 seeds per fruit.

Areoles

Young areoles white-felted.
