material. It ia more than probable, although the fact has 

 not come under my notice, that in many of the species with 

 exalbuminous seeds the cotyledons are subterranean after 

 germination. 



Polygala rarifolia, DC. (fig. 195). 



Hypocotyl suffruticose, erect, terete, pubescent, pale green, 

 5'5 cm. above the soil. 



Cotyledons broadly oblong, obtuse, shortly petiolate, cordate at 

 the base, glabrous, pale yellowish-green, subcoriaceous ; lamina 

 1-15 cm. long, one of them rarely slightly smaller, 7 mm. broad, 

 petiole 2 mm. long. 



Stem suffruticose, erect, terete, hairy, pale green ; 1st internode 

 2-5 cm. long ; 2nd 9 mm. ; 3rd 8 mm. ; 4th 1-25 mm. ; the 

 numerous succeeding ones crowded. Individuals, however, differ 

 in the relative lengths of the internodes. 



Leaves simple, entire, cauline, alternate, exstipulate, shortly 

 petiolate, hairy on both surfaces, pale green ; petioles terete, hairy, 

 about 1-1-5 mm. long. 



Nos. 1 and 2. Oblong, obtuse, minutely cuspidate. 



Nos. 3 and 4. Linear-oblong. 



Nos. 5-7. Oblong, the numerous succeeding ones linear-oblong, 

 obtuse, minutely cuspidate.

The ovary in this small Order consists of two to five 

 carpels, but three is the most prevalent number. It is one- 

 celled with as many parietal placentas as there are carpels, 

 and the numerous small ovules are arranged in a double 

 series. They are amphitropous or subanatropous, ascending 

 on long slender funicles with an inferior micropyle. The fruit 

 is a capsule dehiscing by as many valves as there are carpels. 

 The small seeds are oblong or obovoid, with a crustaceous testa 

 and a linear raphe. 



The embryo is small, axile, and straight, the latter rather 

 unusual in cases where the ovule is amphitropous. This 

 is probably due to its small size, and the fact of its being
