Si LXiii, STYLIDIE^. \_Leven7iookia. 



stem or Lraiiclies, eacli one pedicellate in the axil of a small, leaf-like bract. 

 Capsule glandular-hispid in all the species. 



The genus is limited to the southern colonies and chiefl}' "West Australia, Although 

 very near StyHdium^ with the foliage and habit of some of the series Teuelloi^ it is curiously 

 distinguished by the irritability residing in the hood-shaped labellum, whilst the column is 

 erect and immovable, whereas iu Stylidlum the irritability is in the long, folded colnmn. 

 De Candolle altered the name into Lee^ncenhoekia^ in conformity with the Dutch ortho- 

 graphy of the name of the natural philosopher Leeuwenhoek, to whom it is dedicated ; but, 

 in transferring that name into Latin, or rather in making a Latin word out of it, the modi- 

 fied spelling used by Brown for euphony's sake is in strict conformity with the practice 

 of Jiinna^us and his immediate followers in similar cases, and gives a pronunciation much 

 easier^ and, at the same time, nearer to the true one, than if the original Dutch letters were 

 preserved in languages where they have not the same value. 



Labellum short, nearly sessile at the throat of the corolla or on a short, 

 broad claw. Style without any (or rarely with a small) appendage 

 under the anthers. 



Corolla-tube much shorter than the calyx-lobes, and the lobes not as 

 long again. 

 Glabrous except the calyx-tube. Flowers in a dense, leafy corymb.

Glandular-pubescent. Inflorescence simple or nearly so. 



Labellum scarcely coloured. Style entire 2. i. duhia. 



Labellum dark purple. Style 2-lobed 3. Z. Sonderi. 



Corolla-tube as long as or longer than the calj^x-lobcs. 



Corolla-tube not much exceeding the calyx-lobes; lobes 3 lines 



long. Style 2-lobed 4. Z. pauciflora. 



CoroIIa-tube slender, tmce or thrice as long as the calyx-lobes. ♦

Labellum on a lonp; claw and nearly as long as the other petals. Co-

1. L. pusilla, U. B}\ Prod. 573. Glabrous except the calyx-tube and 

 capsule, 1 to 2 in. or rarely 3 in. lii^h, densely corymbose in the upper part. 

 Leaves obovate or oblong-spathulate, obtuse, rather thick, rarely above 3 

 lines long including the petiole, the leafy bracts similar or narrovt^er, exceed- 

 ing the flowers in some specimens, rather shorter in others. Pedicels short. 

 Calyx rarely I line long, the lobes rather unequal, but variable in breadth 

 and proportion. Corolla-tube very short, 4 lobes having each a short,
