funnel-form, white or white with delicate purple lines, on ter- 

 minal pedicels. Stamens 5, 2 long, 2 short, the fifth smaller. 

 Seeds numerous, in oblong capsules slightly over long. In 

 rocky soil and crevices of flat limestone rocks in dry creek 

 bottoms. 



BORA GIN ACE AE. Borage Family. 



Lappula texana (Scheele) Britton. Stickseed. 



Bur Forget-me-not. 



Hairy plants usually branched above and sometimes at the 

 base, with mostly ascending leaves and tiny, white or pale blue, 

 forget-me-not flowers. Leaves simple, alternate. Blades linear 

 or oblong or narrowly spatulate, entire, 1 to 2" long. Corolla 

 white or blue, very small, 5-lobed, subtended by leaf like bracts, 

 along the upper parts of the stem or its branches. Calyx lobes 5, 

 hairy, slightly exceeding the corolla. Fruits 3 or 4 in a cluster, 

 each a small, hard white cup with inturned margin armed with 

 stout prickles. March, April and May. Commonly known 

 through the pestiferous little burs that get into ones clothing 

 when crossing through fields and vacant lots. Common every- 

 where. The genus name has its origin in the Latin lappa, bur, 

 -ula, little, from the fruit. 



Cryptanthe texana (A. DC.) Greene. 



Conspicuously hairy, branched plants with many branching 

 bractless racemes, the flowers having conspicuously bristly-hairy 

 calyxes and tiny white 5-lobed corollas blossoming out of the 

 unfolding coiled ends of the raceme. Leaves simple, few, alter- 

 nate, the blades narrow or oblong or oblong-spatulate, entire, 

 y 2 to 1" long, very hairy. Sepals 5, narrow, covered with short 

 bristly hairs. Corolla small, white, 5-lobed. March, April and 

 May. In sandy soil. Differs from Lappula texana in the nutlets 

 being smooth and not armed with barbed prickles. Hairs stick 

 in the skin when one tries to pull up plants.
