of Jlanna Loa at elevations of 5000-5300 feet in company with Acacia lua. Myo- 

 porum sandwiccnse, Sophora chrysophylla, and Santahim Fihjcri. 



Until now the plant had only been recorded from Niihaii. Kauai and ]\Iaiii, 

 and that from a lower elevation. 



It is really astonishing to find this curious plant on the slopes of ^lauua Loa 

 in the upper forest zone in company with Sophora and Acacia koa: it is here 

 that the plant reaches a height of more than 30 feet, growing mainly on the 

 many wooded extinct cinder cones and at the bottom of extinct craters as well 

 as all through the forest where it is easy to overlook the plant on account of its 

 leaf whorls being hidden in the branches of Koa and Jlanidni trees. 



At Puuwaawaa. but especially Waihou forest, the plants are numerous, but 

 do not reach such a height as on Mauna Loa. 



Asa Gray says in Proc. Am. Acad, that D. subcordata belongs to this species, 

 but nothing can be more different in habit than these two species; D. siihcordata 

 is a small branching shrub of the habit of a Clermontia (as far as branching is 

 concerned), while D. undulata is not branched and has a single straight slender 

 stem of often more than 30 feet in height. The flowers of D. subcordaia are also 

 larger than in D. undulata. In the Gray Herbarium is a specimen collected by 

 J. Remy on Kauai no. 300 marked Delissea undulata var. attcnuata; the jjlant is 

 identical with D. rhytidospcrnni ilann from the same island. The plants from 

 Niihau collected by Remy are much more robust, the stems being nearly 5 cm in 

 diameter. In the Paris Herbarium are two sheets, one no. 300 ter coll. Remy, 

 leaves deeply serrate on long petioles, no locality given ; the other Remy no. 300 

 bis — from Kauai or Niihau. A duplicate of the latter is in the Gray Herbarium.

Not collected by the writer. 



The plant was first collected by J. Remy on Kauai, but had never been pub- 

 lished by him. There is a specimen in the herbarium JIus. Paris, Remy no. 300 

 without name, which belongs there; a duplicate with the same number is in the 

 Gray Herbarium, ex herb. Paris, labeled "Delissea undulata var. atenuata" and 

 again marked with pencil, "7>. acuniinala."
