The stems grow either erect or ascending and up to 60cm long. An opened flower at the summit together within its toothed green calyx tube, which is between 6 and 10mm long when flowering. Clustered around the open flower are several as-yet un-opened flower buds.
Lower down the stem are the re-closed but expanding sepal cups (calyx)which are expanding to 10 to 20mm in order to accommodated the fruit (a ribbed nutlet) within.

The leaves are ovate to oblong in shape, with 2 lengths of short hairs.

Opened flowers and flower buds at top; expanding calyxes below developing fruits within.

The toothed calyx fits loosely around the yellow corolla tube. The flower can be various colours besides white. Corolla is small, between 7 to 12mm across and yellow on the inside slowly merging to white at the periphery.

3 weeks earlier. The short hairs have tiny glands at their tips which the longer ordinary hairs lack. Both are short.
Five equilength anthers can be seen lurking just within the opening but the stigma is not discernible.

The sepal teeth splay out slightly to allow the 'trumpet horn' part of the flower to flare out.

The stem is square and has longer hairs than the leaves, but again of 2 differing lengths. Each of the 5 sepals has a fold along the centreline, creating a 10-sided container for the fruit.
The leaves clasp the stem at their base.


Some similarities to : Meadow-Foam (Limnanthes douglasii) which also has flowers which are yellow near the middle turning to white near the periphery.

Uniquely identifiable characteristics

Distinguishing Feature :

No relation to : Monk's-hood (Aconitum napellus), Monkey-puzzle Tree (Araucaria araucana), Monkeyflower (Mimulus guttatus), Monkey Orchid (Orchis simia) nor to Monk's-rhubarb (Rumex alpinus) [plants with similar names belonging to differing families].

Yellow Monkswort is a casual neophyte which can be found growing on waste ground or tips or in old gardens. It occurs in Caernarfonshire and Berkshire but can occur scattered over England and Wales.
