Well,this might do for a start.. And if it looks like this then 'it must be a boojum'!
Individual boojum trees can live for up to 100 years, and possibly up to 300 years, reaching a height of 18 metres. But the wood of their trunks is not very strong, so the plants are susceptible to damage by periodic hurricanes, which probably limit their natural age. The trunks of boojums often branch near the tops, and sometimes contort into strange shapes, even bending to touch the ground. The trunks contain succulent tissues that store moisture, so they are of the general type termed stem succulents. They have greyish-white bark and for most of the year are dormant, protected from water loss by a thick epidermal layer. Thin, pencil-like branches arise along the length of the stem and rapidly produce thin, rounded leaves in response to rain. These leaves soon wither and are shed in drought conditions.
