Dracaena scabraThe sword-leaved Dracaena is also known as the Cambodian Dracaena. Sword-leaf Dracaena is an evergreen tree-like plant with a stem height of 5-15 meters. The stem is thick and has many branches. The bark is grayish white and smooth. The bark of the old trunk is grayish brown and peels off in sheets. The young branches have ring-shaped leaf scars. The leaves are clustered at the top of the stem, branches or twigs, overlapping each other, sword-shaped, thin leathery, 50-00 cm long, 2-5 cm wide, slightly narrowing towards the base and then expanding, clasping the stem, and sessile. This species often exudes a small amount of reddish-brown sap at the base of leaves and injured stems and branches. The inflorescence axis is densely covered with papillary short hairs, making it easy to identify. Hainan Dragon Blood TreeHainan Dracaena, also known as the small-flowered Dracaena, is a member of the Liliaceae family. It is a tree-like tree 3 to 4 meters high, with unbranched or branched stems, gray-brown bark, and young branches with dense ring-shaped leaf scars. The leaves are clustered at the top of the stems and branches, almost overlapping each other, sword-shaped, thin leathery, up to 70 cm long and 1.5-3 cm wide, slightly narrowing towards the base and then expanding, clasping the stem, and sessile. It is distributed in the southwest of Hainan, growing on dry sandy soil in the leeward area, and is also distributed in Vietnam and Cambodia. National second-level protected endangered species. Dwarf DracaenaSmall shrub, less than 1 meter high, with thick roots. Stems unbranched or sometimes slightly branched, with sparse annular leaf scars. The leaves grow at the top or top of the stem, at a certain distance from each other, elliptical or elliptical-lanceolate, 20-30 cm long, 6-8 cm wide, with a slightly obvious midrib, and a petiole, 3-6 cm long. The raceme is terminal and about 15 cm long; the flowers are borne 1-3 at a time and are recorded to be about 2 cm long; the pedicels are 3-4 mm long, with the joint at the top. The berries are 10-13 mm in diameter and contain 1-3 seeds. The flowering period is unknown, and the fruiting period is August. Produced in southern Yunnan.

Produced in Guangdong (Hainan Island), Taiwan (Kaohsiung, Tainan) and Yunnan (estuary). It grows on dry sandy soil in forests or under bushes at lower altitudes. Widely distributed in Southeast Asia. Twiggy DracaenaLarge shrub, 1-5 meters high. The stem often has many branches, the branches are relatively thin, and have sparse annular leaf scars. The leaves grow at the top or near the top of the branches, at a certain distance from each other, narrowly elliptic-lanceolate or linear-lanceolate, 10-15 cm long, 2-3 cm wide or wider, with a distinct midrib, petiolate, and a petiole 1 cm long. The panicles grow at the top of the branches and are relatively short, less than 10 cm long; the flowers are usually solitary and have been recorded to be up to 2.2 cm long; the pedicels are up to 1 cm long, with the joint at the top.
