An updated account of the generic richness of Mexican vascular plants records 2,804 native genera, distributed in 304 families. The flowering plants include the largest number (2,663 genera), 2,117 of them dicotyledons (Magnoliophyta) and 546 monocotyledons (Liliopsida). In addition, 127 genera of ferns and fern allies and 14 of gymnosperms are recorded. A list of generic names is provided, as well as a brief discussion about their richness patterns and their geographical and ecological distribution. Of the total generic richness of Mexico, 7.8% (219 genera) is considered to be endemic to this country.

Vascular plants are integrated into coherent bodies via plant-specific synaptic adhesion domains, action potentials (APs) and other means of long-distance signalling running throughout the plant bodies. Plant-specific synapses and APs are proposed to allow plants to generate their self identities having unique ways of sensing and acting as agents with their own goals guiding their future activities. Plants move their organs with a purpose and with obvious awareness of their surroundings and require APs to perform and control these movements. Self-identities allow vascular plants to act as individuals enjoying sociality via their self/non-self-recognition and kin recognition. Flowering plants emerge as cognitive and intelligent organisms when the major strategy is to attract and control their animal pollinators as well as seed dispersers by providing them with food enriched with nutritive and manipulative/addictive compounds. Their goal in interactions with animals is manipulation for reproduction, dispersal and defence. This article is part of the theme issue ‘Basal cognition: multicellularity, neurons and the cognitive lens’.

Penelitian tentang inventarisasi spesies tumbuhan di pulau Barrangcaddi yang berpenduduk padat telah dilakukan. Tujuan penelitian ini adalah untuk mengetahui jenis-jenis tumbuhan asli, tumbuhan introduksi dan tumbuhan invasif di Pulau Barrangcaddi. Kegiatan sampling dilakukan dengan metode purposive sampling. Data diambil dengan mencatat semua spesies tumbuhan yang ditemukan selama penjelajahan di pulau Barrangcaddi. Seluruh sampel di foto. Sampel tumbuhan yang tidak diketahui namanya, di ambil bagian-bagiannya, kemudian dikoleksi dan diidentifikasi di laboratorium Ilmu Lingkungan dan Kelautan, Departemen Biologi, Fakultas MIPA, Universitas Hasanuddin. Identifikasi sampel menggunakan buku: An Annotated Check-List of The Vascular Plants of The South China Sea and Its Shores oleh Turner et al. (2000) dan Mangrove Guidebook for Southeast Asia oleh Wim Giesen et al. (2007) untuk spesies hutan pantai; Tropical flowering plants: a guide to identification and cultivation oleh Kirsten Albrecht Llamas (2003) untuk spesies tanaman hias dan tanaman budidaya/introduksi serta Nonnative Invasive Plants of Pacific Coast Forest. A Field Guide for Identification oleh Gray et al. (2011) dan Guide to The Naturalized and Invasive Plants of Southeast Asia oleh Arne Witt (2017) untuk spesies tumbuhan invasif. Dari hasil penelitian di pulau Barrangcaddi tercatat sebanyak 142 spesies tumbuhan dari 51 suku. Sebagian besar didominasi oleh tanaman hias dan budidaya (introduksi) dengan 103 spesies dari 42 suku diikuti spesies asli (native species) dengan jumlah 29 spesies dari 19 suku. Spesies invasif tercatat paling sedikit dengan jumlah 10 spesies dari 5 suku. Sebagian besar tutupan vegetasi dari spesies asli telah hilang akibat alih fungsi lahan menjadi permukiman.

Since the rise of photosynthesis, life has influenced terrestrial atmosphere, particularly the O2 and the CO2 content (the latter being originally more than 95%), changing the chemistry of waters, atmosphere, and soils. Billions of years after, a far offspring of these first unicellular forms conquered emerging lands, not only completely changing landscape, but also modifying geological cycles of deposition and erosion, many chemical and physical characteristics of soils and fresh waters, and, more, the cycle of various elements. So, there are no doubts that vascular plants modified geology; but it is true that also geology has affected (and, more, has driven) plant evolution. New software, PyRate, has determined vascular plant origin and diversification through a Bayesian analysis of fossil record from Silurian to today, particularly observing their origination and extinction rate. A comparison between PyRate data and geological history suggests that geological events massively influenced plant evolution and that also the rise of nonflowering seed plants and the fast diffusion of flowering plants can be explained, almost partly, with the environmental condition changes induced by geological phenomena.
