Genus difference: Thistle is a grass thistle. Reed is a plant of the genus Phragmites. Different growing environments: Thistle mostly grows at the water's edge below 60m above sea level and on the lower uphill, belonging to amphibians. Reed mostly grows in water, swamps and water. The difference of leaf margin: the leaf margin of the grass is very sharp, but the leaf margin of the reed is not particularly sharp.

What is a flower?

Let's talk about rushes. Many friends mistakenly think it is a reed flower, because the similarity with it is still a little high. In fact, I think this kind of flower is more beautiful than reed flower in sense.

Pteris multifida generally grows outside water areas such as dry land or hills. In late autumn, the grass is golden and the flowers are white. Especially the flowers in the sun or sunset are particularly eye-catching, and the way they dance with the wind is even more beautiful.

So, specifically, what's the difference between reed flowers and grass flowers?

First, the attributes are different.

Tilia amurensis is a perennial herbaceous amphibian, mainly distributed in the Yangtze River basin and its south area. Luhua is a tall grass that has been aquatic or wet for many years, mainly distributed in three northeastern provinces, Mongolia and North China Plain.

Second, the branches and leaves are different

Tilia amurensis leaves are flat, broadly linear, 20-50 cm long and 5- 18 mm wide. Both sides are hairless except for the dense hairs on the upper base, and the edges are serrated and rough. The leaves of reed flowers are needle-shaped, 30 cm long and 2 cm wide, hairless, and the top is tapered into filaments.

Third, inflorescences are different.

The panicle of Tilia amurensis sparsely spread into an umbrella, with a length of 10-20cm and a width of10cm. The top of spikelet stem is slightly enlarged, with short stem length 1-2 mm and long stem length of 3-5 mm. The panicle of reed flower is large, 20-40 cm long, 65438 00 cm wide, and the spikelet stalk is 2-4 mm long.

abstract

Reed refers to the flower of reed, and the flower is the flower of Arundo donax. Although they are similar in appearance, they can be distinguished by careful observation.

Reed is a long inflorescence panicle, usually 20-40 cm long and about 10 cm wide, with many branches.

However, when flowering, the ear will be elongated into an umbrella, which is relatively small and the length is between 10-20 cm. It can be distinguished from the inflorescence size.
