Yungasocereus inquisivensis

 Yungasocereus inquisivensis is a species of cactus native to Bolivia(La Paz), the sole member of its genus, Yungasocereus.

It is a columnar cactus, appearing either as a tree or shrub, ranging up to 4-5 meters in height. The 6-7 cm diameter stems are dark green, with 6-10 ribs. The 1.5-3 cm spines are in groups of 4-12, with no differentiation into central and radial types, and range from a brownish to grayish color. The flowers are white, appearing in groups of 5-8 near the stem tips.

This cactus is known only from Yungas and Inquisivi provinces of La Paz Department, where it is found at elevations of around 2000m.

Cárdenas described the species in 1957 from Inquisivi, placing it in Samaipaticereus. Ritter later found the same species in Yungas, and in 1980 gave it its own genus Yungasocereus. After a period in Haageocereus, this was again separated into Yungasocereus

Botanical Name: Zamioculcas zamiifolia ZZ Plant has become increasingly popular in recent years and I believe it deserves all the attention it’s been getting. The Aroid family has given us more dependable house plants than any other group and Zamioculcas zamiifolia is no exception. This is a worthwhile house plant to add to your collection. ZZ makes a great room accent and practically thrives on neglect. This easy-going house plant is forgiving if you forget to water, tolerates low light, and rarely needs fertilized. Want more? It also seems to shrug off pests. Growing from rhizomes, it has thick, upright stems bearing narrow, dark-green glossy leaves. Keep the leaves clean by gently wiping them with a damp cloth. Don’t use leaf shine products, which can damage the plant. Small, insignificant flowers — consisting of a spadix surrounded by a spathe — may appear at the base of plants in summer, although ZZs rarely flower indoors. A slow-grower indoors, ZZ plant rarely needs...
