1	With one distal bulb	2
	With a pair of distal bulbs	3
2	With marked constriction between the apical and basal parts of the bulb: basal section strongly curved	L. trifolii
	With slight constriction only, between the apical and basal parts of the bulb: basal section not strongly curved	L. sativae
3	With bulb rims circular (not drawn out anterio‐ventrally); evenly sclerotized	L. bryoniae
	With bulb rims spiralled (i.e. drawn out anterio‐ventrally): strongly sclerotized anterio‐ventrally	4
4	With bulbs meeting in the midline only at their rims	L. huidobrensis
	With bulbs meeting in the midline from their rims to their bases	L. strigata
