from the axils of 3 larger bracts ; that the centre one 

 has but one bract while the lateral ones have each 

 three, namely a larger exterior coiTcsponding with 

 the middle one, and two interior lateral ones, thus 

 giving only 5 bracts to the 3 flowers, in place of 3 to 

 each, required by the character. In this species the 

 bracts of the lateral flowers are longer than the 

 calyx, and are prolonged into a long awn-like point. 

 As shown in figure 1, they appear almost like a 

 middle large hermaphrodite flower with a female one 

 on each side, which is simply owing to the lateral 

 flowers being younger than the centre one; figure 

 4, which is one of the lateral flowers more advanced, 

 shows the true structure. 



1770. Chamissoa NODIFX.OBA (Mart.), herbaceous, 

 ascending, branchy, glabrescent : leaves pctioled, spa- 

 thulate or spathulato- wedge-shaped, or oblong, obtuse, 

 with a short point; glabrous or more or less pube- 



the fruit. In this, the seed is enclosed in the thick- 

 ened persistent indehiscent case or utricle, while in 



Amarautus the case splits all round, as in Chamissoa^ 



permitting the seed to di-op out. In modern botanical 

 works the former has received the name of " Utricle,'* 

 while the latter is designated a "Pyxidium." In all 



other respects they are the same. In regard to the 

 characters taken from the bracts and sepals of this 

 species it may be remarked, in passing, that scarcely 

 two plants are alike and that little trust can be 

 placed in them. The species of Euxolus and Ama^ 

 rantm are most difficult to discriminate. 



1774. Banama THYRSiFLORA (Moq.), herbace- 

 ous, erect, branched, glabrous: leaves rhomb-ovate 

 or ovato-lanceolate, acuminate: flowers^ tribra^teate, 



spikes terminal, thyrsoid. 



Eastern slopes of the Neilgherries, from about 

 4000 feet of elevation upwards \ not uncommon. The 



scent : heads of flowers globose, lateral and sub-sessile long pale whitish spikes of this plant render it a 

 or terminal and shortly peduncled : flowers shortly conspicuous object. 

 pediceUed : sepals somewhat longer than the bracts. 



acuminated, keeled, one-nerved : utricle globose. 



1775. PsiLOTRiCHUM KUDTjM (Moq.), stcffi sufiru- 



A common and most variable plant, at least as ^°«^' T^* ''\. sometimes clxmbmg among bnshes : 

 regards size. The specimen represented is a small ^^^^y^^ «^'^^* petioled ovato-lanceolate or ovate, acute, 

 rilid almost shrnbb/one, bnt presents a form not ! ?-ns- -^ ?^J:^^:^^^^^<-r 



uncommon in poor sandy soils. 



1771. Chamissoa dichotoma (Moq.), suffi'uticose 

 or herbaceous, dichotomously branched : leaves short 

 petioled, ovate oblong, obtuse, short pointed, pube- 

 scent, finely ciliate ; heads of flowers lateral, sub-ses- 

 sile, globose, dense ; flowers shortly pediceUed : sepals 

 equaling the bracts, keeled ; keel rough : utricle glo- 

 bose ; seed smooth. 



A diffuse procumbent or slightly ascendmg plant* 

 The station of the specimen represented is not given, 

 but I have specunens, differing somewhat in form, 

 from Courtallum. 



1772. Chamissoa asfeea (R. W. Celosia aspera^ 

 Roth), stems herbaceous, branchy, ascending or more 

 or less diffuse, rough with bristly hairs; or in old 

 plants innocuous prickles : leaves hispid, sub-sessile, 

 from linear blunt to oblong, lanceolate pointed: heads 

 of flowers sub-sessile, globose, dense : bracts as long 

 or longer than the sepals, aristate, pilose: sepals 

 keeled, hahy on the keel : utricle ovoid. 



In com fields in Mysore and Coimbatore. I look 

 upon the plant represented as certainly the same 

 species though it does not quite correspond with 

 Roth's description. This I have ascertained from 

 comparing it with other specimens which do accu- 

 rately correspond, but which I had not before me 

 when the drawing was made. 



1773. EuxoLus cAUBATus (Moq.), stem erect, an- 

 gularly striated, glabrous, green : leaves long petioled, 

 ovate or rhomb-ovate, narrowing^ at both ends, blunt- 

 ish, emarginate, glabrous, gi-een : spikes ascending. 



ers dense, very hairy: sepals much longer than the 

 interior short very broad oblique acuminated bracts. 



In subalpine jungle, sometimes climbing to the 

 extent of several feet among bushes or other sup- 

 port. 



Moquin Tan don has two genera, the present and 

 Ptilotus^ the distinctive characters of which are so 

 much alike that I can scarcely tell to 'which this 

 plant belongs, but I place it here on account of its 

 having opposite leaves, those of the other being alter- 

 nate. With that exception, it seems to me the writ- 

 ten characters are about equally referable to this 



Ptilotus ovatus^ but of th 

 specimen for comparison

1776. This plate furnishes an example of a very 

 unusual error, that, namely, of embodying parts of 

 two very distinct though somewhat similar looking 

 plants. The plant forming the body of the plate is 

 one species, while the flowers that furnish the ana- 

 lyses appertain to another. 



This rather cmious mistake I did not discover 

 until long after the whole impression had been struck 

 off". It originated in the accidental cbcumstance of 

 the specimen represented having been mixed with a 

 number of others, which were given to the artist to 



select from, and being the most suitable in size was 

 naturally chosen, while the flowers of the other, being 

 larger and more easily dissected, were taken for the 

 analysis; the result is the combination in the same 

 plate of 2 very distinct genera, but fortunately both 

 appertaining to the same order and tribe. The plant 

 forming the body of the plate furnishes the type of a 

 new genus, while the dissections represent analyses of 

 thft old crenus JErva, To correct this blunder, per- 



din 



somewhat interrupted below, more compact and sub- 

 cylindrical above : flowers sessile, aggregated in dense 

 glomemles, green: bracts longer than the sepals: 

 utricle globose, pointed^ very rough. 



A common plant, frequent about Coimbatore in 

 waste ground and among rubbish. 



This very common plant is introduced for the pur- 

 pose of illustrating by the analysis the diflference be- 

 tween this genus and Amarantus. This is found in JErva Jloribmda^ accompanied by dissections
