This ant plant belongs to the little-known genus Myrmephytum . It differs from the more familiar Myrmecodia in the arrangement and structure of its flowers and inflorescences, and is particularly striking due to its large, blue flowers.This plant originates from near Nabire, in the Indonesian county of Papua Tengah in New Guinea.
Myrmephytum 'longissimum' is a so-called 'nomen nudum', meaning "naked name." This means that while this plant has a botanical name, there is no scientific description of the species. A plant with similar leaves, but without a known caudex or flowers, was recorded as " Myrmedoma longissima " on a herbarium specimen, but the identity of this plant was never definitively established, and it was never described as a species. A revision integrated the genus Myrmedoma into Myrmephytum , resulting in the new combination " Myrmephytum longissimum ." However, this is not a described species! In the revision of the genus by Huxely & Jebb (1991), it is therefore referred to as " Myrmephytum species 1." Since it is now more commonly known as M. longissimum , we offer it under this (naked) name.
The caudex is elongated, with spiny ridges, and in nature the plant usually hangs upside down from large trees in the lowland rainforest. The surface is covered with numerous small holes.
The long, drooping leaves are particularly striking in this species. They grow to about 45 cm long and 3 to 4 cm wide. The flowers are among the most beautiful and largest in the genus. They are blue, about 5 cm across, and only open for a few days. After a short time, elongated, orange fruits develop from the flowers.
Myrmephytum grow surprisingly quickly with proper fertilization. This bizarre, hanging species is a highlight in any larger terrarium or grow tent.

[expand Title=" About Ant Plants "]
Myrmephytum are so-called "ant plants" from the Rubiaceae family. They are widespread from Southeast Asia to Australia and from Papua to the Solomon Islands, and usually grow epiphytically on trees. They belong to the myrmecodomen ant plants, meaning they provide nesting sites for ants. Their thickened stem, also called a "caudex," is riddled with numerous tunnels and chambers inhabited by specialized ants, mostly from the genus Philidris . The ants do not create the chambers or the entrances themselves; these are formed solely by the plant, regardless of whether ants are present or not.
The plant has a mutually beneficial relationship with the ants that live in it. The ants protect the plant and their nest, and fertilize it with leftover food, droppings, and other waste. The plant contains several different types of chambers: some with smooth walls and others with warty walls. The warty chambers, in particular, are specially adapted for absorbing nutrients. The ants use the smooth chambers for nesting and the warty chambers as a waste disposal site, thus supplying the plant with nutrients. In some highly specialized ant-inhabiting plants, the ants even pollinate the flowers and plant the seedlings!
Over many years, the colonies of ants and ant-attracting plants spread across a tree, and other epiphytes associated with ants, such as Hoya , Dischidia , Lecanopteris , and orchids, also join them. A so-called " ant garden " is created.
Not every ant-friendly plant is actually inhabited by ants in nature. In fact, there are numerous species where ants have never been detected! This also means that no ant-friendly plant necessarily needs an ant colony to survive or thrive. All of our cultivated ant-friendly plants are, of course, ant-free! The caudex forms exactly the same way as it does in nature, even without ants.

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect.
Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr
