Leaves drilled, 4-6 mm long, green, early fall. Radial, 5--6.5 cm in diam.; torus obovoid, 3.3-3.5 cm long, 1.7-2.2 cm in diam., apical truncated and concave, base attenuate, green, sparsely conspicuous, small warts, short trichomes , spineted bristles and burrowed spines; verrucose tepals broadly obovate to narrowly obovate, 10-25 mm long, 6-12 mm wide, apex cuspidate or rounded, apical, yellow, with green ribs Petaloid tepals obovate or spatulate-obovate, 25-30 mm long, 12-23 mm wide, apex rounded, truncate or dimpled, margin entire or shallowly eroded; filaments yellowish, long 9- 11 mm; anthers ca. 1.5 mm, yellow; styles 11-18 mm long, 1.5-2 mm in diam., pale yellow; stigma 5, 4.5--5 mm long, yellowish-white. Berry obovoid, apex depressed, base narrowed to stalk, 4-6 cm long, 2.5-4 cm in diam., smooth surface glabrous, purple-purple, with 5 to 10 raised larvae per side, small With short wool, barbed bristles, and diamond-shaped thorns. Seeds numerous, oblate, 4-6 mm long, 4-4.5 mm wide, 2 mm thick, margin slightly irregular, glabrous, yellowish brown, flowering 6-10 (-12) months.
2 internal structure
The internal structure of the cactus stem is identical to that of other dicotyledons, with a layer formed between the xylem on the inner side and the phloem on the outer side. However, most of the stems consist of thin-walled cells that contain mucinous substances that protect the plants from water loss. The stem of a cactus is the main organ that produces nutrients and stores nutrients.

Clinical PW A detection
Port wine stains ( PWS ) is always a birthmark . It is caused by a vascular anomaly. PA imaging could provide real-time information about the thickness of the skin and diameter. depth, distribution of blood vessel , which provide significant help with clinical diagnosis and treatment.
PAI VS. OCT
Image depth : PA 2 mm
OCT 0.4 mm
Functional identification : With optical fingerprint characteristics ,P A could specificity imaging blood vessels , eliminates the interference of hair follicle, sebaceous glands.
The clinical testing has been carried out in 301 and guangzhou military general hospital , testing and statistic all kinds of PWS lesions in patients with vasculal parameters , in order to establish the classification and quantitative treatment of PWS.
