📚 Overview
Description
Global description
Bulbostylis hispidula is composed of a tuft of long, strongly hispid fluted flowering axes. Leaves, poorly developed, remain at the base. The inflorescence is subtended by 2 bracts. It is composed of 3 to 7 spikelets of ferruginous color, more or less long pedicellate. The fruit is a trigona achene transversely wrinkled and surmounted by a trifid style.
First leaves
The first leaves develop in tuft. They are filiform and hispid, with very short hairs. They are 2 to 6 cm long and 1 mm wide. At their base is a short membranous sheath. The limb is shaped like a gutter.
General habit
The plant is tufted. It is mainly composed of flowering axes that can reach 35 cm in height. The leaves remain at the base of the axes.
Underground system
The roots are fasciculate. They are very numerous, simple and filiform.
Stem
The stems are filiform and cylindrical, with a diameter of 0.5 mm. They are grooved longitudinally and strongly hispid.
Leaf
The leaves are poorly developed and remain at the base of the flowering axes. The blade is filiform and hispid, with very short hairs. It is 2 to 4 cm long and 1 to 2 mm wide. It is shaped like a gutter. At the base of the lamina is a cylindrical sheath that completely surrounds the floriferous axis.
Inflorescence
The flowers are assembled in spikelets 5 to 7 mm long and 2 to 3 mm wide. At the top of flowering axes is a sessile spikelet framed by 3 to 7 spikelets more or less long pedicellate. The inflorescences are subtended by 2 linear bracts 1 to 3 cm long.
Flower
The flowers are bisexual, including a trifid ovary and stamens in the same glume. A spikelet comprises 5 to 10 flowers arranged spirally. The glumes are oval, 2.5-3.5 mm long. The glumes of the base bear a point at the end, those of the summit are only mucronated. They are ferruginous red in color and dotted with short hairs.
Fruit
The fruits are trigonal achenes, obpiriform, yellowish in color. They are long and 1 mm wide and 0.5 mm thick. The summit is surmounted by a trifid style 2 mm long and finely pubescent. The three faces are traversed by 6 to 8 transverse wrinkles.

Life Cycle
Northern Cameroon: Bulbostylis hispidula is observed throughout the crop cycle but its abundance decreases considerably after the first weeding and is only very weak at the end of the crop cycle. This species does not tolerate repeated weeding (weeding, hilling). Germination occurs mainly at the beginning of the cycle (May or June) for one to two weeks. Flowering occurs rapidly, ie 2 to 4 weeks after germination. It is followed a month later by fruiting. This ends with the drying of the plant in late October-early November, at the very beginning of the dry season.

Ecology
Northern Cameroon: Bulbostylis hispidula is a characteristic species of well-drained soils with a sandy or pebbly surface horizon. It is particularly frequent on ferruginous soils and more abundant when the soil is degraded and the plots are old, whether they are grown in a traditional or intensive way. It is not very sensitive to cotton preemergence herbicides. It is an indicator species for the decline of soil fertility. It is completely absent from very young plots (newly cleared) or parcels on vertisols or planosols with a high clay content and high water retention.

Local nuisance
Northern Cameroon: Bulbostylis hispidula occurs in 30% of cultivated plots, from the Sahelo-Sudanian regions to the Sudanian regions. Its abundance increases according to the regional rainfall. On the other hand, it is more abundant at the beginning of the crop cycle than in the middle of the cycle, to be only very weakly represented at the end of the season.
