The sandbox tree can grow to 60 metres (200 ft) in height, [7] and up to 13 metres (44 ft) in girth at 1.8 metres (6 ft) above the ground; [8] its large ovate leaves grow to 60 cm (2 ft) wide. The trees are monoecious, with red, un-petaled flowers. Male flowers grow on long spikes, while female flowers grow alone in leaf axils.
A notable example is the sandbox tree (Hura crepitans), which can fling seeds 100 meters (300 ft) and has been called the "boomer plant" due to the loud sound it generates. Another example is Impatiens, whose explosive dehiscence is triggered by being touched, leading it to be called the "touch-me-not".
I scanned the trees and saw that a maple tree had "exploded". The explosion caused a big crack in the tree about three feet high. When a winter wind stirs the frozen trees, they sometimes appear to burst vertically. When it was 40 degrees below zero at night, I lay awake and listened to the trees explode. That's a true wilderness thermometer!
Published reports of DMT in the leaf [7] derive from a misreading of a paper that found no DMT in leaves of this species. [8] Besides this, there are independent claims of DMT in leaves and bark based on human bioassay, [2] and traces of 5-MeO-DMT, DMT and NMT were tentatively identified by TLC in twigs. [9]
The leaves are ovate to elliptic, simple, and have shallow, rounded teeth on the margins. [8] The seed pods have five valves which coil back rapidly to eject the seeds in a process called explosive dehiscence [9] or ballistochory. This reaction is where the name 'touch-me-not' comes from; in mature seed pods, dehiscence can easily be triggered ...
The crown of leaves is almost spherical in shape, the point of each leaf perfectly marking the shape of the imagined sphere. The leaves crown the trunk in a crowded whorl of long, wiry leaves. They are arranged in a spiral, forming an erect tuft when young and spreading as they mature, with the oldest leaves dying and forming a hanging skirt ...
Tovex Firebreak II used on Upper Bear Creek Trail in the Angeles National Forest. Tovex (also known as Trenchrite, Seismogel, and Seismopac) is a water-gel explosive composed of ammonium nitrate and methylammonium nitrate that has several advantages over traditional dynamite, including lower toxicity and safer manufacture, transport, and storage.
The leaves are microphylls, each containing only a single vein and measuring less than 1 cm (0.4 inches) long. Two types of microphylls are formed, green trophophylls that cover most of the aerial shoots, and yellow to tan sporophylls that form the strobili, and contain the sporangia .
