|
texture |
epidermis, trichome |
Containing deposits of silica, thus hardened and abrasive. |

= medullose |
texture |
|
Loose or spongy internally, denser and firmer externally. |
|
friable |
= brittle |
texture |
|
Dry, firm and easily broken. |
|
chartaceous |
= papery, papyraceous |

|
leathery |
= coriaceous |
texture |
|

fatiscent |
= crumbling; > farinaceous, mealy |
texture |
|
Easily disintegrating in relatively small pieces, either spontaneously or under pressure. |
|
limp |

texture |
|

mucilage |
|
substance |
|
A slimy exudate. |
|
latex pl. latices, latexes |

SUBSTANCE |
|
A moderately viscous and sticky exudate, often milky, sometimes otherwise colored or clear. Overlaps conceptually with gum. |
|
gum |
