A bird-pollinated carnivorous plant? Absolutely! Utricularia menziesii is Australia's own bird-pollinated carnivore, with large, pinkish-red flowers attractive to the Western Spinebill (Acanthorhynchus superciliosus) #ozflora #botany #nature #utricularia https://academic.oup.com/aob/advance-article-abstract/doi/10.1093/aob/mcy163/5087939 …pic.twitter.com/6sITP0uR3E

It is spring in Victoria, and the orchids of the seasonally arid regions of western Victoria are going off now—this is the bloom of the bow-lipped spider orchid, Caladenia toxochila, mainly known from the Little Desert region near Nhill #botany #ozplants #ozflora #orchidaceaepic.twitter.com/iLNx6nLZ0Y

A labelled pen & ink technical illustration of Drosera indica—a carnivorous sundew—prepared for a botanical publication. Inset is a vascularised glandular hair (adapted from Mauseth, 1988) and a unicellular eglandular hair from a scanning electron micrograph (Wise, 2014) #botanypic.twitter.com/KERfjcC1eF

Primula hirsuta growing beneath a partly frozen waterfall; some of the adjacent plants were encased in ice following an ice storm on the flanks of Monte Legnone, above Pagnona, Provincia di Lecco, Lombardy, Italy #botany #primulaceaepic.twitter.com/Q3ykcPycwJ

Fabaceae runs riot in Western Australia, with hundreds of species in many genera. A favourite is Isotropis cuneifolia—Granny bonnets or Lamb poison—the latter name being apt as they contain a potent nephrotoxin, iforrestine; few people have grannies this funky #botany #ozplantspic.twitter.com/t7BUAxDAa1

Corybas incurvus is a relatively small, winter (June to September)-flowering helmet orchid native to VIC, TAS, SA and NSW, Australia. This terrestrial species is widespread and can be locally abundant, but habitat loss has erased numerous former populations #Botany #orchidspic.twitter.com/UmItfE0P1e

Ophrys corsica (1), O. sicula (2) & O. lutea (3), all snapped in Puglia, Italy, are bee orchids separated by differences that some observers would consider inconsequential (labellar flexion, aperture size &c). The real Q is whether these account for different pollinators #botanypic.twitter.com/jmIiBfBYuw

The impossibly hardy Saxifraga oppositifolia (1) growing on a ridge (2) near Rifugio Duca D'Aosta, adjacent to Corno Grande (3), highest point of the Gran Sasso massif & centrepiece of the Gran Sasso e Monti della Laga National Park, Abruzzo, Italy. There are people in 3! #Botanypic.twitter.com/OvTdEc8Fg7

Nepenthes bokorensis is a robust and colourful tropical pitcher plant restricted to Phnom Bokor in Cambodia. These pitchers have developed alongside a widespread sticky carnivore, the sundew Drosera lunata. Seen here at 990 metres elevation on an upland plateau #Botanypic.twitter.com/9SKwjgC2Qw

An undescribed species of dwarf riparian Spathoglottis growing on banks of ultramafic rock that line a river in eastern Sulawesi, far and away the smallest Spathoglottis species I've ever seen in terms of plant and flower size #botany #orchidpic.twitter.com/9QHEFbAjmL

Living up to its name, Coelogyne rupicola (rupes-=rock, cliff; -cola=dwelling) growing on bare, ultramafic rock beneath glaring sunlight at 2700 m elevation on the summit of Tambuyukon, a mountain in the Kinabalu National Park, Sabah, Borneo #botany #orchidpic.twitter.com/1SbhSjQC7w

The cryptic leaves of the Malesian orchid Nephelaphyllum pulchrum can make it a challenge to spot when not in flower, but the blooms of this form are a shock of pink amongst the deep leaf litter of Mount Kinabalu, in Sabah, north Borneo #botany #orchidpic.twitter.com/ScfnsD9vaE

Drosera schizandra may not look like a carnivorous plant as its adult leaves often lack dew. It is believed that this Queensland rainforest-endemic sundew is evolving away from carnivory owing to the inefficacy of flypaper traps in habitats with high atmospheric humidity #botanypic.twitter.com/xjwmML7VxF

Stichorkis pandurata flowering in southern #Sabah, Borneo. Often producing significant amounts of nectar, they are popular with ants, though ants are too small to effect pollination in this species, as indicated by the size of the column #botany #orchidspic.twitter.com/y0XxXHOdeg

Though frequently rare and threatened by habitat loss, bee and wasp mimicking orchids occur widely across Europe, the steno-Mediterranean and westernmost Asia. This is Ophrys promontorii, flowering at one of the strongholds for the genus in Puglia, southern Italy #botany #orchidpic.twitter.com/7meTGYa7QX

The open pitchers of Nepenthes inermis produce a mucopolysaccharide that pours to the ground like diluted honey when they're upended. This substance allows the pitchers to both function as pseudo-flypaper traps & to retain prey during heavy rains. Barisan range, S Sumatra #botanypic.twitter.com/s8JM9jv5dI

Liparis alpina (Orchidaceae) is an ultramontane terrestrial found only in the alpine region of New Guinea, where night temperatures can fall to 0 ºC, 3200 m elevation, Lake Habbema region, West Papua #botany #orchid #florapic.twitter.com/lgcic0os6D

Detail of the flowers of Glomera erythrosma, observed on Mount Puna, central Sulawesi, at 1500 m elevation. This species was hitherto recorded from W Malaysia, Thailand, Laos, Sumatra, Java and Ambon #botany #orchidpic.twitter.com/RF1h58qPr6
