In writing the following descriptions, the view held by recent 

 authors that the organs found, when they do occur, usually at the throat 

 of the calyx of ThymeleacecB are petals, has not been followed. That 

 view was not without support among older writers ; thus Lindley 

 calls the organs in question " scale-like petals," and Eichler alludes 

 to them as ** Kronblatter (Schlundschiippchen)," which ma}^ be re- 

 garded as a sort of " sitting upon the fence " ; but Meisner, whose work 

 upon the group is of great importance, always speaks of " squamulse," 

 while Endlicher boldly names them sterile stamens. Baillon, while 

 adopting the " scale " view, says of Dicranolepis that the scales 

 resemble a corolla. In spite of this extreme case and of a certain 

 analogy with Dichapetalum, it seems not improbable that these 

 organs are really not petals at all, but either transformed parts of the 

 andrcpcium or new structures arising independentlj^ and functioning 

 in the pollination of the respective species bearing them. In any 

 event, it would seem better at the present stage to use a non-committal 

 term rather than the definite one now coming into fashion. 



Struthiola epacridioides C. H. Wright, District of George, 

 Trake de tow ; Bowie, 22. 



Struthiola Pentheri, sp. no v. Fruticulosa, ramis erectis rigidis 

 omnimodo crebro foliosis pubescentibus ; foliis subarcte imbricatis 

 ovatis vel oblon go-ova tis obtusis nisi obtuse acutis jDaucistriatis coria- 

 ceis nitidulis giabris ; fiorlhus ex axillis pluribus oriundis ; hracteolis 

 cymbiformibus ciliafcis apice villosulis ; calycis tubo superne leviter 

 amplificato ipso sub limbo subito paulloque dilatato parum incur vo 

 glabro lobis brevibus late ovatis obtuse acutis ; sqiiamis 8 oblongis 

 obtusis incrassatis pilos cingentes superantibus ; antlieris inclusis

South Africa, Zitzikamma ; Penther, 429. 



Folia 5-7 x 2-3 mm., in sicco viridi-grisea. Bracteolae 2'5-3 mm. 

 long. Calycis tubus infra articulum 1 mm., supra idem 8-9 mm. 

 long., hie inferne '5 mm. superne 1 mm. lat. ; lobi 1*5 mm. long. 

 Squamse 1'2 mm. long. Anthera? squamis sequilongse. Ovarium 

 •7 mm long. 



Distributed as S. Thomsoni Oliv., a native of Tropical East 

 Africa. It is close to S. Macowani C. H, Wright, differing from 

 it mainly in the broader and obtuse leaves and the shorter calyx with 

 but a slight enlargement immediately under the limb.

Struthiola concava, sp. nov. Fruticulus ramosus ; ramulis 

 quadrangularibus foliosis primo ascendentibus postea patentibus
