Nectaniira sp. 



Plate CX, figure 3. 



Description. — Leaves very large, ovate-lance- 

 olate in outline, the acmnen gradually nar- 

 rowed and greatly extended. Margins entire. 

 Texture subcoriaceous. Estimated length 

 about 2.5 centimeters. Maximiun width about 

 7 centimetere. Midrib stout and prominent 

 on the lower surface of the leaf. Secondaries 

 stout, prominent, numerous, distant, opposite 

 to alternate, ascending, camptoch'ome. They 

 diverge from the michib at difl'erent angles, 

 acute below, more open above, and curve 

 upward, regularly below, more abruptly above, 

 until they become subparaUel with the lateral 

 margins. Tertiaries obsolete. 



This extremely large and handsome form is 

 imfortuiiately represented by fragments, the 

 most complete of which is figured. Since no 

 complete specimens have been found, I have 

 not proposed a specific name for this form, 

 although it appears to be entirely distmct from 

 previously described fonns. It is not abmi- 

 dant but appeal's to have had a considerable 

 distribution. 



Occurrence. — ^Lagrange foiTuation (m beds of 

 Wilcox age), Puryear, Henry County, Teim. 

 (collected by E. W. Beri-y). Wilcox group, 

 sec. 28, T. 13 N., R. 12 W., De Soto Parish, La. 

 (collected by G. C. Matson) ; Old Port Caddo 

 Landing, Little Cypress Bayou, Harrison 

 County, Tex. (collected by T. W. Vaughan).

Cryptocarya eolignitica. Hollick, in IlarrLs, G. D., and 

 Veatch, A. C, A preliminary report on the geology 

 of Louisiana, p. 283, pi. 42, fig. 1, 1899. 



Description. — Leaves oblong-ovate and 

 slightly inequilateral in general outline, taper- 



ing rather al)rui)tlv to th(> shortly pointed 

 apex, broadly rounded and slightly decm'rent 

 at the base. Length about 13 centimeters. 

 Maxununi width at or below the middle aljout 

 4.6 centhneters. Marguis fuU, entire, slightly 

 undulate. Texture coriaceous. Petiole stout, 

 about 1.5 centini(>ters in length, sHghth' curved. 

 Midrib stout, somewhat flexuous. A single 

 lateral primary diverges from the mithib on 

 each side about 1 centimeter above the base 

 at a wide angle, cmTes abruptly upward and 

 then slightly outward, somewhat flexuous, 

 arching from the ends of straight lateral 

 branches of the loweiinost secondaries close 

 to the marguis at or shghtly a])Ove the median 

 region of the leaf. The latends are tliinner 

 than the midrib and subopposite. Seconda- 

 ries, tln'ce or four chstinct subopposite or 

 alternate pair's, in the upper hah' of the leaf, 

 diverguig at a wide angle and strongly cm^^ed, 

 camptodrome. Tertiaries thin, mostly per- 

 cmTcnt except for a series of straight-sided llat- 

 arched loops from the outer sides of the lateral 

 primaries, from wliich they diverge at a ^vide 

 angle of almost 90°, the arches appi'oximately 

 parallel with the leaf margins. 



Tliis clearly distinct species is represented 

 by the fine and nearly complete leaf figured liy 

 HoUick, and unfortunately no additional mate- 

 rial has been found. It is clearly a member of 

 the Lam'aceiT? and very likely of the subfamily 

 Lauroideae (tribe Cryptocaryefe), although it 

 resemliles in a general way some species of 

 C^mamomuin, Oreodaphn(>, Nectanch'a, and 

 the hke, of the subfamdy Persoidese. 



In a note appended to Ins paper on the plants 

 from Louisiana Holhck cal's attention to cer- 

 tain Chilean species described by Engelhardt 

 from the South American Tertiary as Goep- 

 pertia,' particidarly troeppertia spectahilis, with 

 wliich he is disposed to identify the leaf from 

 Coushatta. I have compared the two forms 

 carefully and also compared them with the 

 material representing Goeppertia in the her- 

 barimn of the New York Botanical Garden. I 

 do not tliiiik the foi-m from Louisiana is iden- 

 tical wntli that from Cliile. Cryptocarya R. 

 Brown comprises oidy 10 South American 

 species, the 30 additional fonns being widely 

 distributed in southeastern Asia, Africa, Oce- 

 anica, and Australia. The genus Aydendron,
