Bulbous Buttercup
Bulbous Buttercup - Ranunculus bulbosus
Short to medium hairy plant with a swollen corm-like base. The flowers are golden yellow 20 to 30 mm on furrowed stems, sepals down-turned.
Often confused with R repens and R acris - all are common in grassland
Basal leaves - a short section of stalk separates final leaf lobe from two basal side-lobes. Sepals turn downwards ('reflexed') alongside the flower stalk; this distinguishes it from R repens

Grassy habitats on well drained calcareous or slightly acid soils. Meadows, pastures, road verges, etc.
March to July.
Perennial.
Very common throughout Britain.
Very common also in Leicestershire and Rutland. In the 1979 Flora survey of Leicestershire it was found in 482 of the 617 tetrads. It is listed as Native and Locally Abundant in the current Checklist (Jeeves, 2011)

Sciapteryx consobrina
The larvae of the sawfly Sciapteryx consobrina feed on members of the Ranunculus family and on Moschatel . Sciapteryx consobrina larvae are highly variable both in colour and black patterning. The ground colour can vary from yellow, grey, green to absolutely black with the complete pattern of the black spots on the one hand to the specimens with the black spots completely missing on the other hand. Likewise, the black head pattern is also highly variable varying from black headed larvae to the quite orange headed larvae with all conceivable intermediate variants between them.
Phytomyza fallaciosa
The larva of the Agromyzid fly Phytomyza fallaciosa mines the leaves of various members of the Buttercup family. A brown blotch is eventually formed, without green patches. Primary and secondary feeding lines are generally clear. Pupation occurs within the mine.
Urocystis ranunculi
Urocystis ranunculi is a smut fungus which affects certain Buttercup species causing stems etc. to blister and eventually erupt, exposing a mass of dark spores.
Phytomyza ranunculi
The larva of the Agromyzid fly Phytomyza ranunculi mines the leaves of various members of the Buttercup family including Lesser Celandine. In this species the grains of frass are closely adjoining or grouped. Identification is more difficult when the mine is in the stem.
Phytomyza ranunculivora
The larva of the Agromyzid fly Phytomyza ranunculivora mines the leaves of various members of the Buttercup family of plants. In this species the mine is linear, whitish, with frass in widely spaced grains.
