Still, the F train has proved more popular than its above-ground counterpart.
Its roots penetrate more than 18 feet deep, and its above-ground shoots can spring from either the underground stems or the roots.
The design presented to the commission last week shrank the museum's profile from the original plan, moving part of the building underground and reducing its above-ground square footage by 17 percent.
Such usage forces the water district to tap into its above-ground water tanks, which hold 1.25 million gallons and act as reserves in the event of a fire or when there is unusual demand.
This month, the San Francisco Municipal Railway opened an extension of its above-ground F line, which since 1995 has used a small fleet of streetcars from the 1920's, 30's and 40's on a round-trip route along Market Street between Castro Street and the Transbay Terminal, downtown.
Its above-ground portions die during summer, and its root becomes the storage organ and therefore becomes heavier, a mechanism that implies more harvest yield than at other growth stages.
The kind of data we deal with in a case study of vegetatively propagating woodreed (Calamagrostis epigeios) is called 'identified individuals with unknown parents' (Logofet, 2008, 2013c): we determined reliably the age-stage-specific status of each individual plant from the morphology of its above-ground part, but the parent progeny rhizome links remained reliably hidden in the ground.
For all its above-ground newness, the subterannean Los Angeles has proved, over the years, to be an archaeological museum of Native American, Spanish and European artifacts.
MTRCL indicated in rail merger discussions that it would carry out a review of the feasibility of installing public toilets at or in the vicinity of its above-ground railway stations.
If the stem or roots of the plant are damaged -- for example your toddler sits down on top of your 18 inch plant, snapping it near its base -- you can often save the plant anyway, by burying much of its above-ground stem and lower branches again, as you did to 75% of the plant when you first placed it in the ground.
