Several years ago I received a parcel in a padded bag. Taken for reuse in September, I found some dark-brown triangular nut-like seeds in it which were planted and some germinated within days. The first picture shows one of the resulting plants. The leaves are opposite with glands along veins on rear and around the margins. The white flowers are carried at the head of the stem and on shoots from the leaf axils. The second, the seed formation. The tallest plants have reached 35 cms. What are they, please?
