A charming little plant, worthily dedicated to its discoverer, who has 

 added more to our knowledge of the New Zealand orchids than any other 

 observer of late years. It is closely allied to the Western Australian T. varie- 

 gata Lindl., principally differing in the much smaller size, in the solitary 

 flowers, and in the column-wing scarcely crested on the back behind the 

 anther. Mr. Matthews informs me that the remarkable spiral twist or 

 coil in the leaves is constant in all the specimens he has seen. This pecu- 

 liarity is also more or less observable in T. varieqata.

In the Manual I have alluded to the fact that at least three of the New 

 Zealand species previously referred to Cardamine differ from that genus 

 in the seeds being 2-seriate, the species in question being C. fastigiata, 

 C. latesiliqua, and C. En>jsii. Scliulz, in his monograph of Cardamine 

 (Engl. Jahr., 32) excludes all three from the genus, but does not make any 

 other disposition of them, lie also removes C. stijlosa, in this instance
