1. 单瓣型Single.
It has one row of not over eight petals, which can be regular, irregular or loosely arranged about a central, conspicuous stamen cluster, but without petaloids. 'Spencers Pink', 'Kamohonnami', and 'Alba Simplex' are typical examples. The Japanese, who favor the single type, have again divided this group into six classes:

| 11 |
Standard 单瓣标准型 筒咲き |
This is the typical wild Camellia japonica flower form with five to seven irregular, overlapping petals in a single row and a more or less columnar stamen cluster. |  |
| 12 |
Campanulate 单瓣喇叭型 ラッパ咲き |
This is the trumpet shaped single of petals with narrow bases and reflexed apices and a columnar or tubular stamen cluster. |  |
| 13 |
Wabisuke 佗助型 猪口咲き（ワビスケ咲き） |
This is a miniature to small single form, usually vase shaped with an abortive stamen centre. |  |
| 14 |
Cup-shape 杯型 盃状咲き（盃咲き） 椀咲き |
Known as sake cup shaped in Japan. In this form the base of the petals are broader and the bloom, when open, is truly cup shaped with none or little reflecting of the apex. Stamen cluster can vary from columnar to spreading. |  |
| 15 |
Spherical 包圆型 抱え咲き |
This is called the 'male-in-one' form in Japan and refers to single flowers where the petals are incurved to obscure the stamens. |  |
| 16 |
Saucer-shape 肥后型或碟型 平開咲き |
In this case the single blooms open almost flat with a strong stamen centre. The typical Higo camellia, if not more than eight petals, falls within this type. The stamens can be circular or spreading. |  |
2. 半重瓣型semi-double.
It has in excess of eight petals in two or more rows, with a conspicuous stamen centre, with no petaloids. The petals may be regular, irregular or loose. Examples are 'The Czar', 'Akashigata', 'Finlandia' '. In Japan this class is divided into three types:

| 21 |
Standard 荷花型 蓮華咲き |
It has two or three rows of imbricated petals. In China this form is known as the lotus. |  |
| 22 |
Magnolia 玉兰型 八重咲き |
In China the magnolia form is a single of the shape of a Mignolia denudata bloom. |  |
| 23 |
Doubleness(hose-in-hose) 双层瓣型 二段咲き |
This has the appearance of a second flower superimposed on the first and, in Japan, is fairly common with the larger 'snow camellia' (C. rusticana) cultivars, although rarely seen in the West. |  |
3. 托桂型Anemone form.
This form is the same in the Orient or the West, and has one or more outer rows of large petals while, in the centre, the stamens have become almost totally petaloid and form a convex mass in the centre of the flower.

| 31 |
Single 托桂型 唐子咲き |
It has one row of outer petals and a very compact centre. 'Anemoniflora' and 'Bokuhan' are typical examples. |  |
| 32 |
Multiple rows of outer petals 外瓣多层 |
It is larger with two or three rows of outer petals and a more open central mass, sometimes with many small petals as well as petaloids. 'Elegans', 'C.M. Wilson' and 'Extravaganza' are examples. |  |
4.牡丹型Peony form.
It also known as the informal double.
| ID | Standardized Name | Description | Sample Photo |
| 41 |
Peony 松散牡丹型 牡丹咲き |
The loose informal double, or the incomplete informal double. This has loose petals, usually irregular or wavy, becoming smaller-to the centre, where they are divided by fascicles of stamens; sometimes the centre is a mixture of small petals, petaloids and stamens. Examples are 'Betty Sheffield', 'Kickoff' and 'Emperor of Russia'. |  |
| 42 |
Full(no stamen) 牡丹型 獅子咲き |
The full or complete peony, or the complete informal double. This is usually a convex mass of a mixture of irregular, twisted petals and petaloids, with the stamens, if any, obscured. Examples are 'Debutante' and 'Madame Picouline'. |  |
5.玫瑰型（蔷薇型）Rose form.
| ID | Standardized Name | Description | Sample Photo |
| 51 |
Standard 标准玫瑰型 バラ咲き |
This has multiple rows of imbricated petals, opening through a bud-shaped centre to show some stamens in a concave centre when fully open. Examples are 'Shiragiku', 'Red Robin' and 'Sharon Rose'. |  |
| 52 |
Bud-centered 牙尖中心玫瑰型 宝珠咲き
|
The centre petals remain firmly embraced, forming a bud like centre. Because this bud centre is similar to the pointed ball pediments known as 'honju', seen in Japan and China on posts and towers, it is named the 'honju' form in Japan. |  |
6. 完全重瓣型Formal double.
It has many rows of regular, overlapping petals and has no stamens. It was called the 'perfection' in the 19th century.
| ID | Standardized Name | Description | Sample Photo |
| 61 |
Imbricate 全重瓣型 千重咲き |
There is the usual, fully imbricated formal double, such as 'Alba Plena' and 'C.M. Hovey'. |  |
| 62 |
Tiered 六角型 列弁咲き |
There is the tiered form where the petals are arranged to form a star shape. This is called the procession form in Japan or hexangular or radiate type in China. 'Incarnata' and 'Hexangularis' often open with this form. |  |
| 63 |
Spiral 螺旋型 |
A rarer form is the spiral form where the petals are arranged in rows in such a manner to form a five armed or seven armed spiral. The most famous Camellia with this form is the Italian ' Vergine di Collebeato '. |  |
