Morphological characteristics
Trees, 10-15 m high; glabrous except for young, inflorescence, and ovary slightly pubescent; bark brown or light brown, rough, with longitudinal ribs. Branchlets have small, dense lenticels. Pinnate compound leaves 12-25 cm long; petiole 1.5-3 cm long; stipules caducous; leaflets (3-)4-5(-6) pairs, nearly leathery, ovate or elliptic, long ( 2.5) 4-7(-9) cm, width 2-3.5 cm, 1 leaflet at the top of the compound leaf is the largest, descending downward, the base 1 is only 1/3 of the length of the top leaflet, and the apex is acuminate or acute Blunt, basally rounded or broadly cuneate; petiole 3-5 mm long. Panicles axillary, 8-10 cm long, 6-7 cm in diam., branched into corymbose; peduncle 3-5 cm long; basal bracteulate nearly triangular, 0.5 mm long, secondary calyx bracteolate Wide ovate, ca. 1 mm long; flowers ca. 5 mm, initially crowded at the apical branch appressed, then gradually alienated; pedicel ca. 1 mm; calyx ca. 2 mm, below 1 calyx tooth longer, lanceolate The rest of the eggs are broadly ovate and cuspidate; corollas are milky white or yellowish, and each is approximately equal in length. Each has a petal shank of about 1 mm in length, and the flag is heart-shaped. The shank is about 5 mm long and the upper part is about 3 mm wide. Apex flattened, slightly indented, wing flap oblong, keel half-moon shaped, dorsal arch; stamens 9, simple; ovary narrowly elliptic, long-stalked, stalk ca. 2.5 mm, ovules 1-2 grain. Capsule oblong, 4.5-8 cm long, 1.5-1.8 cm wide, slightly basally hairy, blunt or pointed at base, abruptly narrowing base to connect with slender fruit neck, fruit neck 5-10 mm long, Fruit flap leathery, the part of the seed is obviously raised, shaped like a piece, up to 5 mm in thickness, with 1 (-2) seeds.

[3] Trees, 10-15m high, except for young, inflorescence, and ovary slightly pubescent, the others are glabrous.
Branchlets have pale, dense lenticels. Odd pinnate compound leaves 12-25cm long; petiole length 1.5-3cm; leaflets 9-13, dilute to 7, nearly leathery, ovate or elliptic, 4-7cm long, 2-3cm wide, apex acute Blunt, base rounded or cuneate; panicles axillary, pedicel 8-10 cm long; bracts and bracts broadly ovate, ca. 1 mm; flowers small, numerous, ca. 5 mm; calyx campanulate, About 2mm long, split teeth 5, 1 lower teeth below; corolla yellowish or milky white, flagged nearly petaloid, apex slightly dimpled, wing petal oblong, keel crescent, each valve clawed; stamens 9 , monomer; ovary narrowly elliptic, style short. Follicles long oblong oval, 4.5-8cm long, fruit flap leathery, with a network of veins, seed 1, thin 2. Flowering from March to April, fruiting from October to November.
Indian Dalbergia
Large deciduous trees. Bark gray, dark brown with heartwood; branchlets puberulent. Total petiole curved and alternate; leaflets 3-5, broadly elliptic or ovate, 2.4-7.2 cm long, apex acuminate, pubescent when young, gradually glabrous after fully growing. Indigo grows panicle clusters; peduncles, pedicels, branches and pods are coats. The upper two teeth are nearly circular, the rest are lanceolate; the flowers are yellowish-white, nearly sessile; stamens 9, simple; ovary pubescent, style shorter than ovary. Capsules linear-lanceolate, 4-10 cm long; seeds 1-3. Flowering March-April, fruit ripening November.
Face
shield is a protective device commonly used to protect wearer's entire face (or part of it) from hazards such as flying objects and road debris, chemical splashes (in industry), or potentially infectious materials (in medical and laboratory environments).
The shield can be made of PC, PVC, wire mesh for use in different workplace.
