Accordingly, she decided to publish all her new species in this specialized field in a new series, Mesembryanthemum and allied Genera. These descriptions began appearing in 1927 and were published in three parts (1928, 1928-1935, and 1936-1958) by the Univer• sity of Cape Town. From 1960 to 1969 the descriptions were continued under the same title in the Journal of South African .

In 1919 Louisa published a small booklet, Elementary Lessons in Systematic Botany. This was followed later by two more ambi• tious books, A Book of South African Flow• ers (1925) and A Second Book of South African Flowers (1936), both contained col• ored illustrations. The University of Stel- lenbosch awarded Louisa an honorary D.Sc. degree in 1936. She was a member of the International Organization for Succulent Plant Study (IOS). In May 1969, Louisa was named a Fellow of the CSSA. The in• scription on the award certificate: "Curator of the Bolus Herbarium, University of Cape Town for 43 years; describer of about 1,700 species of succulents, primarily Mesem• bryanthemum; author of many publica• tions." Louisa's last publication, Notes on the Mesembryanthemum and Allied Genera, appeared in the May 1969 issue of the Jour• nal of South African Botany and at the con• clusion of the article appeared the usual "To be continued."

She died at age 93 in Cape Town on 5 April 1970. •
