Dr. Sherwin Carlquist Collection

In honor of National Library Week, BRIT Library would like to highlight a recent acquisition of the BRIT Library & Archive collection.

In July of 2018, BRIT Library acquired the collection of botanist Sherwin Carlquist. This acquisition includes 100,000 color field photograph slides, 5,000 microscope slides, and 15 field notebooks.

Carlquist is a Guggenheim fellow and a plant anatomist based at Santa Barbara Botanic Garden Herbarium (SBBG) in California and continues to publish on his research findings to this day. Over the course of his career, the primary focus of his research has been on island biogeography and island flora. The most active years of his field research span from 1953-1989 and include regions such as Western Australia, New Zealand, Hawaii, Japan, Malaysia, and Africa.

Carlquist often collected three types of specimen samples while out in the field collecting: a wood sample, a sample for liquid preserve, and a sample for the main herbarium collection. Carlquist’s wood collection, liquid preserve collection, as well as his main herbarium specimen collection are housed at Rancho Santa Ana Herbarium (RSA). There are upwards of 5,000 Carlquist specimens in the RSA collection.

Carlquist’s fifteen field notebooks, now housed in BRIT Library & Archive, range to include his research from 1951-2012, which was conducted in the regions of Australia, Tasmania, New Zealand, New Guinea, Kenya, Western Australia, New Caledonia, Japan, and South Africa.

Part of the value of field notebooks is that they often provide important date, locality, and determination (identification) information regarding the specimen collected. The specimen and field notebook are typically correlated by way of a collection number assigned to the specimen by the botanist. Oftentimes, without the information provided in the field notebooks, collections of specimens cannot be processed and accessioned into herbaria collections, and therefore cannot be used for research.

While out collecting in the field, Carlquist also took field photographs of specimens before they were collected. Field photographs include photographs of plants as well as photographs of habitats and they are taken in situ primarily for two reasons. The first relates to the specific environment of collection: some aspect of the geography, microclimate, and ecosystem of the specimen locality is valuable to the identification of the specimen. The second pertains to the structure of the plant: some physical element of the specimen will not be preserved in its collection, pressing, and drying. Carlquist took field photographs of both plants and habitats.

Botanists and horticulturists love a challenge. That’s why this year we’re introducing a new feature in the newsletter: What Is This Thing? This month, Martha L. of Fort Worth asks us to identify a plant with small flowers than never open. The answer tells a fascinating story about the reproductive strategies of plants–and why some prefer closed to open marriages.
