Representatives of Williamsoniacae (Bennettitales) are usually restored as small-leafed shrubs or low-growing trees with densely interlaced stems bifurcating or trifurcating at broad angles—a growth form referred to as divaricating. A divaricate plant architecture has evolved independently in at least 18 modern plant families, of which the majority occur in New Zealand, where they constitute more than 10 % of the flora. Botanists favour two or three hypotheses on the benefits of a divaricating… 
Jurassic Flora in Southern Mexico: Anomozamites Schimper, 1870 Emend. Pott et McLoughlin, 2009 from Mixteco Terrane, Phytogeographical Implications of Williamsoniaceae Family (Bennettitales)
Anomozamites is a fossil-genus of leaf attributed to the Bennettitales, with a distribution mainly in the Kingdom of Laurasia and a stratigraphic range of the Upper Triassic to the Lower Cretaceous.
Exceptionally well-preserved Early Cretaceous leaves of Nilssoniopteris from central Mongolia
Abstract Two new Early Cretaceous (Aptian-Albian) species of fossil bennettitalean leaves are described from central Mongolia and assigned to the genus Nilssoniopteris. Nilssoniopteris tomentosa
Biota and palaeoenvironment of a high middle-latitude Late Triassic peat-forming ecosystem from Hopen, Svalbard archipelago
Abstract A siliceous permineralized peat block recovered from Hopen in the Svalbard archipelago hosts a low-diversity Late Triassic flora dominated by autochthonous roots and stems of bennettitaleans
The diversity of Australian Mesozoic bennettitopsid reproductive organs
TLDR
The extremely low representation of reproductive organs vis-à-vis foliage is interpreted to reflect a combination of physical disintegration of the seed-bearing units while attached to the host axis and, potentially, extensive vegetative reproduction in bennettopsids growing at high southern latitudes during the Mesozoic.
Eobowenia gen. nov. from the Early Cretaceous of Patagonia: indication for an early divergence of Bowenia?
TLDR
Fossil foliage Almargemia incrassata from the Lower Cretaceous Anfiteatro de Ticó Formation in Patagonia, Argentina is re-examine in the light of a comparative cuticular analysis of extant Zamiaceae, and phylogenetic analyses indicate that a newly erected genus could be related to extant Bowenia.

TLDR
Wielandiella definitely forms a separate genus within the Williamsoniaceae that is distinct from Williamsoniella and Williamsonia and circumscribes a whole-plant concept that includes branched axes bearing leaves, immature seed cones, and monosporangiate, flowerlike reproductive structures.
SELECTIVE FORCES INFLUENCING THE EVOLUTION OF DIVARICATING PLANTS
TLDR
Divaricating plants evolved in New Zealand as one of the responses of a sub-tropical flora, isolated from sources of artic-, alpine-, and desert-adapted plants, to the onset of harsh glacial climates.

Abstract:  Rögla is the northernmost locality yielding Mesozoic plant fossils in Scania, southern Sweden, and is one of the northernmost Rhaetian assemblages in Europe. The assemblage consists of

It is now generally recognised that the Benettitales occupied a dominant position in the vegetation during part of the Mesozoic period, and the elucidation of their reproductive structures is

Photoinhibition under drought and high light loads in New Zealand's divaricate shrubs
TLDR
The absence of a strong difference in the amount of photoinhibition between divariacte and non-divaricate congeners mean that high irradiance and drought stress are unlikely to have been a key factor in the evolution of the divaricate habit.
Relationships between moas and plants
TLDR
The preliminary conclusion reached is that mammals are equivalent to moas only in a limited site-specific sense, in particular, on lowland highfertility sites such as river terraces, and the effects of introduced mammals are either relatively minor or are a major new effect on the vegetation.
