Xerophyte

Central Spines

1-4, one much longer about 26 mm long, spreading or turned downward light brown, hardly distinguishable from radial spines

Seeds

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

Description

Parodia concinna subs. agnetaeSN|3536]]SN|15619]] is small cactus species forming a flattened and much-ribbed sphere that could develop several 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 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.

Roots

Fibrous.

Flowers

1-5 produced together at the apex, funnel-shaped, bright yellow, large, about 5 cm long and wide. 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. The flowers are self-incompatible.

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

16 to 30 about 6 mm broad at the bas, with chin-like tubercles between the areoles

Stem

Simple, broadly globular to inverted pear-shaped 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 white to light brown, with darker dots.

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, then bare, rounded, up to 3 mm in diameter and about 6 mm apart.
