Bamboo subfamily

Bamboo subfamily(Bamboo Aka,Bambusoideae) IsPoaceaeIt is one subfamily of.BambooEtc. are included.

In the past, a very large group was sometimes referred to as the Bambusoideae, but now it isGrass Phylogeny Working Group "Bambusoideae in the narrow sense" defined by (GPWG) in 2001Bambusoideae sensu stricto) ”Is standard.

In English, the (narrowly defined) Bambusoideae Bamboo Collectively called (Bamboo Is sometimes used in a narrower sense), in this sense Bamboo Is usuallyBambooTranslated as.

Positioning within the Gramineae family

In the past, there is a theory that it was the first branch in the Gramineae family.Bambusoideae (Bambusaceae) Was sometimes made independent.

In the currently known strain,OryzoideaeAlong with (Poaceae), it is included in BEP clade, which is an evolved group in the Gramineae family. "BEP" is the name of three subfamilies Bambusoideae,Ehrhartoideae,Pooideae OfAcronym.


According to the classification by GPWG, the subfamily Bambusoideae is Takeren (bambuseae) When Olyreae It was divided into reams.

TakerenKimotoBamboo (woody bamboos) Also called, in a broad senseBamboo(SasaEtc.). Although it is said to be "wooden", it is secondary to normal woody, although it is made into wood.Hypertrophic growthI don't.on the other hand,Olyreae RenHerbBamboo (herbaceous bamboos), Which is a normal herb.

But Sungkaew et al. (2009)[1]According to the molecular phylogenetic analysis of Bambusoideae, the Bambusoideae are not monophyletic but divided into two strains, tropical Bambusoideae and temperate Bambusoideae.Tropical big bamboos with OlyreaeSister groupsThe temperate Kimoto bamboos are sister groups to all of them.From this result, they selected temperate woody bamboo from Takeren. Arundinarieae It should be divided into reams.

The base of the leaf wraps around the stemLeaf sheathForm, butSedge familyIt is unlikely that both ends of the petiole will fuse to form a tube.In addition, a fin-like protrusion is formed at the tip of the leaf sheath, which is called (yozetsu).The leaf blade may swell all the way to the leaf sheath, which is called the leaf ear.There are many groups that use leaf tongue and leaf ear as a guide for species identification.

StemHas knots, leaves are attached to each knot, and roots appear on the circumference.The stems are often hollow, with sharp knots.Stems can become woody and stiff, especiallyBamboo subfamilyThings are strong enough to be used for timber.however,CambiumBecause there is no such thing, it does not grow and become fat.Depending on the classification system, Bambusoideae may be separated from Gramineae and treated as Bambusoideae.

Growing environment

There are many kinds, and some grow in various environments.森林,(I.e.Some grow in, butPrairieIs often composed mainly of gramineous plants.

In grasslands where dicotyledonous plants grow, the top layer tends to be concentrated and the inside tends to be dark, but the grasslands formed by grasses have stems and leaves, so the light reaches the roots. Enters.

A group of people with excellent skills will soon文明There is a historical background that has prospered as.

Typical usage example

The Gramineae are some of the early branched subfamilies that are primitive and estranged from each other.BEP clade(Rice, wheat, bamboo, etc.),PACAD cladeIt is divided into two large monophylies (corn, millet, Japanese millet, Japanese pampas grass, etc.).BEP clade と PACAD clade Are sister groups to each other.[2]

There are various theories about how to divide them into subfamilies and reams, but they are becoming more and more organized as the lineage becomes clear.Shown hereGrass Phylogeny Working Group[3] There are about 12 subfamilies of 40 subfamilies.moreover Micrairoideae There is also a theory that admits subfamilies[4]But according to recent research Micrairoideae Is not a monophyletic[2]The position is uncertain.

Subtribes are omitted, and only important genera and species are listed.

Primitive grass family

Anomocroa subfamily Anomochlooideae

It is the most basic group of Gramineae, and is a sister group to all other Gramineae groups. Both of them belong to one genus, and both grow on the floors of lowland forests in Central and South America.

  • Anomochloeae : Anomochlia Anomocroa genus
  • Streptochaeteae : Streptochaeta Streptochaeta


  • Phareae


  • Puelieae
  • Guaduelleae

Spikelets tend to degenerate from the tip in the case of many flowers and two flowers.
