Justification
Lachenalia martiniae is known from four to five locations. It has lost habitat to citrus cultivation. It is potentially threatened by future road widening, further crop cultivation and future urban development. It has an extent of occurrence (EOO) of 959 km², and is therefore listed as Vulnerable under criterion D.
