MATEEIALS FOE A FLOEA OF FOEMOSA. 9 



exception, two parietal placentae, which connate themselves in the 

 innerside of the capsnles. But, it is quite otherwise with the 

 present plant, which bears only a placenta rising b}^ itself to mid- 

 way from the base of the ovary, i.e. a central placenta, as is the 

 case with Scrophulariaceous plant. The genus is, therefore, not to 

 be referred to Hydrophyllacese, but should be referred to 

 Scrophularine93. There is a little difference between his state- 

 ment and Mr. Making's drawings, regarding the placenta. So far 

 as I can judge from the latter figures, the ovary is perfectly two- 

 celled, with axial placentae. Bnt, in the figures given in Hookee's 

 Icônes Plantarum, the ovary is nearly, but not perfectly, two- 

 celled, as the placentae are free at the apex. Although these 

 differences exist, they are, in my opinion, to be regarded as 

 results of individual mutability, to which all plants are more or 

 less subject. Taking all these things into consideration I think 

 the plant should be referred to »Scrophularineae, as was stated 

 formerly by Bâillon and quite recently by Prof. Beand. Finally, 

 1 may mention one more plant which is also extremely difficult 

 as to its reference. It is Triplostegia glandulifera Wall. The 

 genus was first established by Wallich on a Himalayan plant 

 in liis manuscript and also in DC. Mem. VII. t. 4, referring it 

 to Valériane«), as we see in "DC. Prodr. IV. p. 642." 

 The genus is, however, transferred to Dipsaceae by Bentham 

 and HooKEE, f. in their Genera Plantarum II. p. 158, with the 

 remark "Genus liucusque ad Valerianeas quibus inflorescentia 

 accedit adscriptum, sed involucellum, semen albuminosum, folia 

 et indumentum omnino Dipsacearum ct odore Valerianearum 

 caret," and also on p. 1230, with another remark, " Stamina per- 

 fecta saepe 3 tantum ut in Valeriana aflhiibusque, et genus 

 omnino medium tenorc vidctur inter Valerianeas et Dipsaceas,
