LOASE.E 581 



Loasa vulcanica, Andr. 



Hypocotyl finely glandular-pubescent, variable in length accord- 

 ing as the seeds are germinated in heat or out of doors. 



Cotyledons ovate-rotund, glandular-pubescent on both surfaces, 

 and 4-5 mm. long, 4-6 mm. wide, with a slender petiole channelled 

 above, 1-75-7 mm. long. 



Stem annual, erect, terete, densely covered with patent, glandular 

 hairs of different lengths ; 1st internode 1-4 mm. long. 



Leaves cauline and very similar to those of L. lateritia. 



First pair ovate, obtuse, distantly serrate-dentate.

Fruit and Seed. This small Order has a superior one- 

 celled ovary and three parietal placentas on which the numerous 

 ascending anatropous ovules are arranged in a double series. 

 The fruit is capsular, many-seeded, and dehisces loculicidally 

 throughout its length by three valves. The seeds are oblong- 

 cylindrical, sometimes with a prominent raphe and chalaza, 

 reticulate or covered with small depressed areas and slightly 

 curved. They are furnished with a membranous aril along 

 the same side as the raphe. The endosperm is copious and 

 fleshy. The embryo is straight, axile, and narrow, with 

 plano-convex cotyledons and an elongated radicle. 



Seedlings. The only seedling of this Order coming under 

 my notice is Turnera elegans (fig. 372) . The cotyledons are 

 ovate, petiolate, with a distinct midrib and two faint lateral 

 nerves. The first two leaves are opposite, oblong-lanceolate, 

 incise-serrate, while succeeding ones are alternate. A peculiar 

 feature of the venation is that the primary veins run into the 

 sinuses, not the teeth of the leaves. In some species of 

 Turnera and Wormskioldia the ultimate leaves are pinnatifid. 



Turnera elegans, Otto (fig. 372). 



Hypocotyl erect, terete, pubescent or hairy with upcurved and 

 incurved hairs, pale green, 1-1'5 cm. above soil.
