Submerged leaves are thread-like with 12–20 leaflets. Intermediate leaves are thicker with 6–8 short pinnae, transitioning into smooth linear terete forms. ''Myriophyllum crispatum'' is monoecious. The male flower has 4 cream to dark brown or purple petals. The female flower lacks petals.

Water Milfoil
''Myriophyllum'' (water milfoil) is a genus of about 69 species of freshwater aquatic plants, with a cosmopolitan distribution. The centre of diversity for ''Myriophyllum'' is Australia with 43 recognized species (37 endemic). These submersed aquatic plants are perhaps most commonly recognized for having elongate stems with air canals and whorled Leaf, leaves that are finely, pinnately divided, but there are many exceptions. For example, the North American species ''M''. ''tenellum'' has alternately arranged scale-like leaves, while many Australian species have small alternate or opposite leaves that lack dissection. The plants are usually heterophyllous; leaves above the water are often stiffer and smaller than the submerged leaves on the same plant and can lack dissection. Species can be monoecious or dioecious. In Monoecy, monoecious species, plants are hermaphrodite, while in Dioecy, dioecious species, plants are either male or female, the flowers are small, 4(2)-parted and us ...

Monoecious
Monoecy (; adj. monoecious ) is a sexual system in seed plants where separate male and female cones or flowers are present on the same plant. It is a monomorphic sexual system comparable with gynomonoecy, andromonoecy and trimonoecy, and contrasted with dioecy where individual plants produce cones or flowers of only one sex and with bisexual or hermaphroditic plants in which male and female gametes are produced in the same flower. Monoecy often co-occurs with anemophily, because it prevents self-pollination of individual flowers and reduces the probability of self-pollination between male and female flowers on the same plant. Monoecy in Flowering plant, angiosperms has been of interest for evolutionary biologists since Charles Darwin. Terminology Monoecious comes from the Greek words for one house. History The term monoecy was first introduced in 1735 by Carl Linnaeus. Darwin noted that the flowers of monoecious species sometimes showed traces of the opposite sex function, ...

Flora Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae ('' Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae (''Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the large ...
