Australian National Botanic Gardens

Plant Enquiry Service

The Australian National Herbarium provides plant identifications and advice on most botanical subjects. Enquiries submitted will be replied to by letter. Some may need to be referred to experts elsewhere, in which case you will be advised.

Fees

General public and scientific or educational enquiries are free; commercial enquiries may attract a charge of up to $20-00 per specimen for a complete identification.

Lodging Specimens

Specimens should wherever possible be brought in person to the Visitor Centre during open hours (9.30 - 4.30 every day except Christmas Day). If this is not possible, specimens may be sent by mail after they have been pressed and air-dried (see guidelines below).

Specimens will not in general be returned unless this is specifically requested.

Up to ten specimens per batch will be accepted; larger batches can only be accepted by specific arrangement with the Herbarium.

Public Reference Herbarium

The Public Reference Herbarium is located in the Visitor Centre, and contains sample specimens for comparison with the material to be identified. It is being developed to cover all native and introduced taxa on the South Coast and Southern Tablelands. A library of reference books is also available. The Public Reference Herbarium is for do-it-yourself identifications, although assistance can be provided on request.

Student Enquiries

Post-graduate student enquiries should be arranged with the Herbarium Curator (Bob Makinson, ph. 250 9466, email rom@anbg.gov.au). University undergraduate student enquiries, if related to assignments, cannot in general be accepted unless the enquirer has tried using the Public Reference Herbarium and associated library; all students are encouraged to use the P.R.H. and the associated reference books, in the Visitor Centre.

Collecting

For regular collecting, or for occasional trips where a lot of material is being gathered, please contact us and we will issue you with a more detailed booklet of collecting techniques, and an ANBG collecting book (which has useful prompts for what data to collect). We can also offer training sessions.

Permits

Please remember that permits are required to collect plants of certain species in certain areas, particularly in reserves. Permit procedures differ, but details can be obtained from the wildlife management authorities (usually national Parks and Forestry services) in your state or territory.

Identification Enquiries

In order to give you a positive identification, we need to know:

• Where the plant was collected (distance from a town along what road, etc), and whether the plant was growing in full bush, disturbed or semi-urban bush, pasture, or in a garden. For wild plants, what sort of country was it - wet, dry/scrubby, tall forest, rocky slopes, river flat, etc. What other plants were around? Also note altitude, rock-type, soil-type, and latitude and longitude if known.

• What it looked like. Was it a tree, shrub, prostrate (flat to ground) shrub, or a herb (non-woody plant), or climber? What colour were the flowers when fresh? What colour and texture was the bark? Did it root-sucker?

• A good specimen. Samples about 30 cm (1 foot) long are usually adequate. They should be as complete as possible; i.e. they should include buds, flowers and/or fruits as well as a piece of stem bearing typical leaves. If leaf shape or size vary greatly on the plant, make a note and take separate pieces from different parts of the plant to represent the variation. For some genera, fruits and/or seeds are essential for a positive identification; e.g. Hakea, and many in the families Asteraceae (daisies), Ranunculaceae (buttercups), Chenopodiaceae (saltbushes), Caryophyllaceae, and Geraniaceae.

Preparing Specimens

Plants should be pressed as soon as possible after collection, before wilting. Specimens should be pressed flat and dried between sheets of semi-absorbent paper (e.g. newspaper) interleaved with sheets of thick cardboard or light plywood. The whole lot can be strapped together in a plant press, or stacked carefully with weights on top. Good air circulation is essential; presses dry well on a car roof-rack in fine weather. Some plant groups are difficult to identify and we require special information:

Ferns

Include both fertile (spore-bearing) and sterile fronds, as well as part of the rhizome (creeping "root") if there is one, and the base of the stipe (leaf stalk). For Tree Ferns, collect a portion of a fertile frond, and the base of the stipe with any scales or hairs.

Herbs

For small herbs, collect one to several whole plants, including any underground storage organs (bulbs or tubers), or if plant is locally rare then leave these in ground and make notes on what these parts looked like (this allows the plant to regenerate - especially important for rare species, including many orchids).

Grasses (and grass-like plants, including rushes and sedges)

Collect whole plant or small clump, including roots. For grasses, make a note of whether the plant was easy to pull up (annual) or difficult to pull (usually a perennial). Grasses and sedges are best collected after the flowers have opened but before the fruits have dropped.

Eucalypts

There are over 700 species, some very hard to distinguish. Specimens should include adult leaves, flower buds (better than open flowers!), fruits, and (when present) juvenile leaves from low on the plant or from suckers near the base of the trunk. You must make notes describing:
• the habitat (e.g. alpine, along a river bank, grassland or forest, disturbred area)

• the habit (height, one- or several-trunked)

• the type of bark (smooth, smooth with scribbles, rough stringy, rough flaky, rough and strongly ridged, etc). If the bark is even partly rough, how far does this extend (just a sock near base, up to first branch, over trunk and main branches only, over fine twigs as well)? If bark is more or less smooth all over, what colour(s) and patterns?

Acacias

Even more species than eucalypts. Collect adult leaves, juvenile leaves if present, flower buds just before opening, and mature pods if possible.

Grass Trees (Xanthorrhoea)

Note the lengths of the flowering and non-flowering parts of the spike ("spear"), and of the trunk (if any) below the leaves . The middle part of the spike (including the base of the flowering/fruiting portion and the top of the smooth portion) should be collected, as should a few complete leaves, including the leaf bases if possible. Be very careful not to damage the plant when collecting leaf bases; Xanthorrhoeas grow very slowly and may be a hundred or more years old.

Water Plants

Do not keep in water after collection. Drain excess water off and lay the plant between newspaper sheets for a few minutes, then press and dry between fresh papers.

Algae

Will not be identified by the ANBG herbarium. Small (often microscopic) algae from blooms in rivers or dams can be collected in a waterproof container in the water in which they were found; keep refrigerated. They can be identified by the local Water Resources authority, who will give instructions on how to send samples. Large algae (e.g. seaweeds) can be collected as for water plants (above), and should be sent to The Enquiry Counter, National Herbarium of NSW, Mrs Macquaries Rd, Sydney NSW 2000.

Mosses, Lichens, Liverworts

Try to include fruiting bodies (tiny capsules or disks or "umbrellas" on stalks, or cupped to spherical appendages). Remove a few square centimetres of the plant mat gently from the substrate or (if adhering closely to bark, soil crust, or rock) cut or chip away pieces of the substrate with the plant in place. If specimen is bulky or very wet, flatten it very carefully. Do not squash or press - place each specimen in a separate paper (not plastic) bag with a collection number and notes, and allow to air-dry. Pack well to avoid squashing before mailing.

Fungi

Try to collect a range of individuals from immature to adult, and record colours and substrate. Dig out the whole fungus, including the base of the stalk. Wrap in greaseproof paper or place in brown paper (not plastic) bag. A spore print is useful - cut off an adult cap (if present), and place gill-side down on a sheet of white paper; cover with a bowl or bucket for a couple of hours until the spores drop onto the paper; send this carefully with the specimen. Speed is essential, especially with fleshy species.

Specimens for the Herbarium

Your specimens, even of common species, are scientifically valuable, and may be incorporated into the Herbarium. Good data is essential for such collections. It is worth remembering also that many new species turn up initially as one-off collections by wildlife management personnel who see an anomalous plant and send it to an accredited herbarium for identification.

Bibliography and self-help

An annotated selected bibliography of useful referecnces is available at the Visitor Centre. Many of the books in this bibliography are also availble for public use at the Public Reference Herbarium at the centre and members of the public are encouraged to identify their own specimens.
