'''''Myoporum viscosum''''', commonly known as '''sticky boobialla''', is a plant in the figwort [[Family (biology)|family]], [[Scrophulariaceae]] and is endemic to [[South Australia]]. It is unusual in that sometimes, especially when the leaves are crushed, it has an extremely unpleasant smell.

==Description==
''Myoporum viscosum'' is a shrub which sometimes grows to {{convert|2|m|ft|sigfig=1}} in height with young branches that are flattened and sticky. The leaves are arranged alternately and mostly {{convert|20-52|mm|in|sigfig=1}} long, {{convert|7-20|mm|in|sigfig=1}} wide, thick and stiff. The base of the leaf partly wraps around the stem and the leaf blade is folded or curved with serrated edges and has many oil dots.<ref name=Chinnock>{{cite book|last1=Chinnock|first1=R.J.

The flowers appear in the leaf axils in clusters of 5 to 8 on a stalk {{convert|4-8|mm|in|sigfig=1}} long. There are 5 triangular [[sepal]]s and 5 [[petal]]s joined at their bases to form a bell-shaped tube. The petals are white with a slight purplish flush and purple spots. The petal tube is {{convert|3-4|mm|in|sigfig=1}} long, the lobes are about the same length and the inside of the tube as well as the bases of the lobes are hairy. The main flowering period is from June to November and is followed by fruits which are succulent, rounded purplish [[drupe]]s around {{convert|3-5|mm|in|sigfig=1}} in diameter.<ref name="Chinnock" /><ref name="eflora" />

==Taxonomy and naming==
''Myoporum viscosum'' was first formally described by botanist [[Robert Brown (Scottish botanist from Montrose)|Robert Brown]] in ''[[Prodromus Florae Novae Hollandiae]]'' in 1810<ref name="APNI" /><ref name=Brown>{{cite book|last1=Brown|first1=Robert|title=Prodromus Florae Novae Hollandiae|date=1810|location=London|page=516|url=https://www.biodiversitylibrary.org/item/21871#page/384/mode/1up|accessdate=3 December 2015}}</ref> from a specimen collected at [[Memory Cove]]. The [[Botanical name|specific epithet]] is derived from the [[Latin]] word ''viscum'' meaning "bird-lime" with the ending ''-osus'' "abounding in", that is, "sticky" or "viscid".<ref name="Chinnock" /><ref name="Sharr">{{cite book |author=Francis Aubie Sharr |author-link=Francis Aubie Sharr |title=Western Australian Plant Names and their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, Western Australia |isbn=9780958034180 |page=337}}</ref>

==Distribution and habitat==
For many years this species has been confused with the much more common species ''[[Myoporum petiolatum]]'' which has thinner, noticeably [[Petiole (botany)|petiolate]] and non-odorous leaves.<ref name="Chinnock" /> ''Myoporum viscosum'' has a restricted distribution encompassing [[Kangaroo Island]] and coastal areas of the [[Eyre Peninsula|Eyre]] and [[Yorke Peninsula|Yorke]] peninsulas.<ref name="Chinnock" />

==Use in horticulture==
Sticky boobialla is a hardy plant which can tolerate salt spray and can be used as a low screening plant. It is readily propagated from cuttings and grows best in full sun.<ref name=Wrigley>{{cite book|last1=Wrigley|first1=John W.|last2=Fagg|first2=Murray|title=Australian native plants : a manual for their propagation, cultivation and use in landscaping|date=1983|publisher=Collins|location=Sydney|isbn=0002165759|page=272|edition=2nd}}</ref>
