As a horticulturist with a keen interest in tropical fruits, I've often been asked to differentiate between lychees and other similar fruits, such as the rambutan. Both lychees and rambutans are members of the Sapindaceae family and are native to parts of Asia, which is why they are often confused. Let's delve into the characteristics that make each fruit unique.

Lychee (Litchi chinensis):

1. Size and Shape: Lychees are generally smaller than rambutans, with a distinctive heart shape. They are about 2 to 4 cm in diameter.

2. Outer Skin: The lychee's skin is red when ripe, which is a key identifier. Unlike the rambutan, the lychee's skin is rough and bumpy, often compared to the texture of a golf ball.

3. Flesh: Inside the rough exterior, lychees have a translucent, white, and juicy flesh that is sweet and slightly tart. The texture is often described as similar to that of a grape.

4. Seed: At the center of the lychee is a single, inedible seed that is dark brown and somewhat hard. The seed is large, leaving little room for the surrounding flesh.

5. Taste: Lychees have a distinctive flavor that is often described as floral and sweet with a hint of citrus. They are highly aromatic and are known for their refreshing quality.

Rambutan (Nephelium lappaceum):

1. Size and Shape: Rambutans are slightly larger than lychees and have a round to oval shape.

2. Outer Skin: The rambutan's skin is also red when ripe, but it is covered in soft, hairy protuberances, which give the fruit its name ("rambut" means "hair" in Malay).

3. Flesh: The flesh of the rambutan is described as sweet, creamy, and rich, with a floral undertone. It is similar in texture to the lychee but is often considered more succulent.

4. Seed: Like the lychee, the rambutan has a single seed in the center, which is surrounded by the edible flesh.

5. Taste: The taste of the rambutan is often compared to that of the lychee but is generally considered to be sweeter and less tart.

Key Differences:
- Texture of the Skin: The most noticeable difference between the two is the texture of the outer skin. Lychees have a rough, bumpy skin, while rambutans have a hairy, soft exterior.
- Size: Rambutans are generally larger than lychees.
- Taste: Although both fruits are sweet and have a floral note, the lychee is often described as having a more tart flavor compared to the richer, creamier taste of the rambutan.

When it comes to consumption, both fruits are enjoyed fresh, and they can also be used in a variety of culinary applications, from desserts to cocktails. They are both highly perishable and should be consumed soon after purchase.

Now, let's transition into the Chinese translation of the above information.
