          denticulate a character which is I believe very uncommon in that
 genus have you observed it on fresh flowers? For I have often been deceived
 in that respect in examining dried specimens.


 Of the two Grecian labiatae No 1 from Ithaca is [Prasium] major
 [crossed out: the] No 2 from Castri is Stachys swainsonii


 Hyptis floridana appears to be only one of the numerous
 forms assumed by the very variable Hyptis spicata


 The Stachys from Florida differs from any I have but belongs
 to a most intricate net, it comes nearest S. Drummondi from which
 it differs in the form of the leaves which are those of some varieties
 of S. [Stachys] mairei but it has not the flower of the latter. The
 arrangement of the hairs of the stem & other characters remove
 it from S. aspera and hyssopifolia.  I should therefore say it is a
 new one to be placed next S. Drummondii.


 The Pycnanthemum does not appear distinct from [?]


 You will have seen in the Feb'y [February] No of D Hooker Companion
 to the Bot. Mag. a Synopsis of [Gerardoa?] in which the Macranthera
 is properly cited the name Conradia being preocupied. I was
 not aware of two species and should feel very much obliged
 by a specimen of the no 2 (M. Le contei Torr.) the one I prefer is
 Nuttall's with toothed [crossed out: calyx] segments of the calyx. I should 
 be very glad could you procure me tolerably authentic specimens
 of Gerardia fasciculata Ell. [now Agalinis purpurea] G. [Gerardia] plukenetii Ell. G. longifolia Nutt. [now Agalinis nuttallii] 
 G. linifolia Nutt. [now Agalinis linifolia] and G. filifolia Nutt [now Agalinis filifolia] and of Seymeria pectinata
 Pursh in flower.


 I have lately published Part VIII of my Labiatae being
 the last or rather the first as it contains the title General
 Geographical Distribution and Synopsis of the Genera. I will
 send your copy by the first opportunity. As to Scrophulariaceae
 I did not undertake to do them in the same detail as I have
 the Labiatae it takes too much time and the printer's bills are
 too high but I shall probably publish some more partial
