Characteristic

A Midori Natsu-related herb [¹]. The rhizome is short and becomes aggregated and stands diagonally, and there is squama and produces a leaf a lot. I reach 100cm, and it is colored straw, but the base is slightly big, and, as for the leafstalk, a color is sometimes dark 40-60cm in length. There is hair, but I gradually fall off and suffer from hairlessness, and there is squama again in a base. The squama of a rhizome and the hypopodium is 1.5cm in length, 3mm in width with a big thing in a lancet arch. There is hair on quality of film, a relationship and the surface with ecru from brown, and a base makes it quality of wood to some extent, and the surface of the part which therefore I had after falling off may become rough.

When the blade is 50-100cm in length, but the small thing is big from 30cm; to 130cm. The width is 30-60cm, but may reach 90cm. The tip is double life from three times feather form incision with the wedge that tsukidashi, the base are large with an egg-formed long oval wide for rough shape slightly. The feather piece had a pattern, but pinnule did not have a pattern, and the base opened diagonally; become wedge-shaped. The base of the sliver plays to a small shaft of a quill and becomes a connection, the narrow wing. Dull saw teeth form a line, or the edge of the sliver is shallow, and it is split into a feather form more or less. I branch 2 tines whether the lateral vein does not branch it, and the sputum not to hold does not reach the edge. I hang the leaf side in the leaf side from quality of grass, a leafstalk in light green from yellow green, and there is much hair.

The sorus forms a line at the midrib of the sliver and the middle with the relationship and is, and the indusium is small, and kidney-shaped, there is hair.

By being a princess bracken, and the Japanese name being similar to a bracken, but knowing a leaf more finely, and, furthermore, being thin, and being seen feebly [²]. By the way, it is big, and Ikehata writes whether this is because "it has style" than a bracken to say ヒメ [³].

Distribution and growth environment

It is from Middle Tohoku region and to the south in Honshu and is seen in Shikoku, Kyushu and I hang it in Australia from Southeast Asia in the foreign territory and am distributed widely. In addition, I am naturalized in North America [⁴]. I am not distributed over Ryukyu Islands, but アラゲヒメワラビ which is a later basic variety is seen in each island [⁵].

I am seen from the sun of the low land to the village and have a weed-like property [⁶]. I am seen in the fields and mountains commonly [⁷].

Intraspecies mutation

The basic variety is called アラゲヒメワラビ T. torresiana var. torresiana. Hair occurs with a large pattern than this variety more thickly [⁸]. In addition, that there is more multicellular hair, and the thing consisting of 5 cells is included [⁹]. That I am seen than this variety in the south and am in Izu Islands, South Shikoku, West Kyushu, southern part, Ryukyu and appear well along the forest relationship and the river of the sun [¹⁰].

In addition, I call a thing without the hair like this seed with トウヒメワラビ T. oloigpphlebia, and Tagawa does this with variety var. oligophlepis of this kind [¹¹]. It is said that this is found in Japan in the southern part of China, but, in Iwatsuki, in compilation (1992), "the distinction seems to be not to admit as difficulty" in this [¹²].

Close species, similar kind

A thing, a sliver having a pattern in pinnule with a plant similar to the whole take the big angle for an axis, and the parallel direction can distinguish congeneric ミドリヒメワラビ T. viridifrons to a main shaft at lengthening points [¹³]. Besides, there are some a lot of congeneric kinds with the similar thing. But there are many kinds similar to the thing which is not closely related like later description in this kind.

Thing with the name of ヒメワラビ

The plant with the name of ヒメワラビ is seen how many on plural courses of the fern. They are considerably surely similar by the appearance, and all have a leaf of the above-mentioned jugum with a green soft plant twice. As for these, there are many things named as a thing similar to this seed whereas this seed was named by the comparison with the bracken [¹⁴]. As a result, to a thing having the name of the bracken, for example, like Ko-ya bracken and Ceratopteris thalictroides apparently at all bracken and 似 てもにつかないものがあるのに vs. do it, and there are many things similar to the thing having a name of ヒメワラビ even if far-off systematically with the appearance [¹⁵]. I put below them up.
