Acacia phlebophylla, an Acacia also known by the names Buffalo Sallow Wattle and Mountain Buffalo Wattle, is a straggling shrub to small, twisted tree reaching up to 5 meters in height. It is a close relative of Acacia alpina.[2] It has large, elliptic, flat, commonly asymmetrical phyllodes 4-14 cm long, 1.5-6 cm wide, with coarse veins, a leathery feel, prominent nerves and reticulated veins. Deep yellow rod-like flowers appear in spring (June-December in Australia), widely scattered on spikes 4-7 cm long, followed by 7-10 cm long legumes in November-March, narrow, straight or slightly curved, releasing 5-10 elliptical seeds, 5-7.5 mm long. Solitary or twinned spikes, to 6 cm long. Only known from the high altitude granite slopes of Mt. Buffalo National Park, Victoria, Australia, where it occurs above 350 meters in woodlands and heathlands often amongst granite boulders.

This is one of the purest natural sources of the psychedelic drug dimethyltryptamine, also known as DMT, which occurs as the predominant alkaloid throughout the plant. However due to conservation issues this species is not considered a viable source of tryptamines, as outlined below. A much more common species such as Acacia obtusifolia, should be researched instead.

Recent reports on regrowth after the 2006 bushfires indicates that the phyllodes of young plants have little to no dimethyltryptamine content. This is presumed to be due to the young age of the plants versus the old growth that stood before the fire.


  • Care must be taken with this species as it consists of one population or metapopulation which has been ravaged over the years by bush fires and fungal infections. Acacia phlebophylla is listed as rare and threatened by the Victoria Department of Sustainability and Environment. There is significant concern for the viability of this population, particularly with the threat of fungal pathogens and other disturbances. (A particular species of local wasp may be associated with the transmission of this fungal pathogen.)
  • Looking/walking amongst them from stand to stand has been strongly advised against, due to the risk of spreading the fungal pathogen which at the moment is their greatest threat.
  • Though there are many accounts of bountiful regrowth, this species should not be used for the extraction of drugs for conservation reasons. Attempts at ex-situ cultivation have been mostly unsuccessful and have usually resulted in plants dying at 3 years. If cultivation is successful, it is important that plants are allowed to mature and produce seeds for eventual rehabilitation rather than used for tryptamine production.

Healthy plants exist in private gardens near Gatton, Qld, as well as in Ireland, indicating the plant is not as recalcitrant in cultivation or restricted to its alpine environment as was once thought.

If attempting cultivation, the following have been found successful for achieving healthy plants beyond 3 years:

- Filing or sanding two places on the seed coat until the inner white germ appears, then planting about 1.5 cm below the surface, and keeping the soil moist but not wet. Doing this usually achieves germination in less than one month.

- "Innoculating" the soil around the seed with soil from the root area of another healthy Phlebophylla, other Acacia, or other Fabaceae, so that root-symbiotic microbes will be present. (Comments regarding the fungal pathogen matter are welcome here.)

- Planting in genuinely well-draining, well-composted, mature, rich soil. (Seed raising mix could do temporarily in an emergency, but is not advised. Commercial composts or potting mixes are unsuitable, due to their nitrogen-stealing high-sawdust content.)

- Avoiding over-fertilising.

- Noting that the first set of leaves are typical Acacia-like, and not mature Phlebophylla-like.

- Noting that it tolerates frosts well, and does best in highly exposed and sunny positions.

- As its roots rapidly travel far down, ensuring it is planted in the land or in tall pots (the larger the better).

- Whenever possible, land planting is better than pot planting. To prevent transplanting, allow for an eventual diameter of two metres.

- Ensuring that water is ALWAYS available to its root tips, but that overall the soil is fairly dry. (Placed on a dry berm nearby a constantly running stream is ideal. If in a pot, water from above - just enough to ensure that the shallow catch-pan it sits in is always full. Ensure the pan is cleaned regularly, to avoid a salts build up.)

- Not watering with heavily chlorinated tap water (which would harm beneficial soil microbes).

Please add your own successful cultivation protocols and practices, so that other specimens can benefit.
