OF ARTS AND SCIENCES: OCTOBER 14, 1862. 37 



1. Characters of some New or Obscure Species of Plants, of 

 Blonopetalous Orders, in the Collection of the United 

 States South Pacific Exploring- Expedition under Captain 

 Charles Wilkes, U. S. N. With various Notes and Re- 

 marks. By Asa Gray. (Continued from Vol. Y. p. 352, 

 November, 1861.)* 



Cyrtandrce Polynesienses. 



Since the publication of the diagnoses of the Cyrlandrce of the 

 Sandwich Islands, specimens collected in our Expedition at the Soci- 

 ety and Samoan or Navigators' Islands, accidentally mislaid, have 

 come to light. C. hiflora, the original of the genus, is the only one 

 recorded from the Society Islands. But we have now tolerable mate- 

 rials of two other Tahitan species, as well as four or five from the Sa- 

 moan or Navigators' Islands. 



Ctrtandra biflora (Forst.) : arborea, pube furfuracea crocea 

 nascentium partium mox delapsa glaberrima ; foliis (3 - 5-pollicaribus) 

 ovato- seu lanceolato-oblongis utrinque subacutis Ijevibus subtus palli- 



* Cyathodes Douglasii, of the preceding paper, p. 325, proves to be C. imhricata, 

 Stschelglew, in Bull. Soc. Mosc. 32, p. 10, a memoir published in the year 1859, 

 which I had overlooked. 



Nama. The following is supplementary to the revision of this genus published 

 in the preceding paper, p. 337 : — 



Specimens of two new species of Nama, collected somewhere in the interior of 

 California, probably in the southern part of the country, by Mr. Lobb, have been 

 communicated to me from the Hookerian herbarium. They do not fall well into 

 place under any of the divisions in my revision ; but one of them might stand 

 next to N. origanifolia, although it has the inflorescence of N. sericea ; the other 

 should be placed between N. hispida and N. sericea, having the white villosity of the 

 latter and the slender sepals of the former. The distinctive characters are annexed. 



Nama Lobbii (sp. nov.) : albo-pilosa ; caule basi suflFruticuloso ; foliis anguste 

 spathulatis basi longe attenuatis vix petiolatis subtus pilis arachnoideis albo- 

 villosis ; floribus subsessilibus congestis ; sepalis angustissime linearibus sursum 

 attenuatis corolla tubum (limbo paullo longius) subsequantibus ; ovario stylisque 

 hirsutis. Corolla 5 lin. longa. — California, Lobb, No. 108. 



Nama ststtla (sp. nov.) : viscosohirsutula ; caule debili ; foliis ovatis petiolatis ; 

 pedunculis gracilibus cymoso-plurifloris ; sepalis angustissime linearibus superne 

 baud dilatatis hispidis corolla triplo brevioribus ; stylis longe ultra medium connatis 

 inferne cum ovario hispidis. Corolla semipolHcaris, angusta. — California, Lobb, 

 No. 164. The connate styles, united for more than two thirds their length, are 

 peculiar to this species.
